Abstract

An electronic control system is disclosed to control and to prevent damage to a standalone or a network of oil free, two stage compressor packages. The electronic control system uses pressure and temperature sensors to detect actual shutdown conditions or predict shutdown conditions based on the operating state of the compressor package and the current temperatures or pressures of the air at strategic locations in the compressor package. It has been determined through experimentation that, if the pressure at the inlet of the stage two compressor is less than the discharge pressure of the stage two compressor by more than an allowable value, then a high temperature condition will occur in the stage two compressor and cause the compressor to seize. It has also been determined that pressure differential occurs first in this situation and that the electronic control system can predict the failure based on the pressure differential data and to shut the compressors down before the stage two compressor failure occurs. The electronic control system then records the shutdown event in an area of nonvolatile memory and displays the reason for the shutdown on a LCD display visible to the compressor operator. A plurality of electronic control systems can be connected in a peer-to-peer network to coordinate control of a plurality of compressors connected to the same air distribution system. A modem connected to the electronic control system supports remote diagnostics, monitoring, and control. Methods for controlling the operation of the compressor packages using the electronic control system are also disclosed.

Description

482878 Λ? —— ___— ^ V. Description of the Invention (ί) Background of the Invention (Please read the precautions before filling this page) The present invention relates to electronic control systems and control methods for operating one or more machines. More specifically, the present invention relates to electronic control systems and control methods for operating one or more oil-free compressors. More specifically, the present invention relates to electronic control systems and to control one or more oil-free two-stage screw compressors. Rotary screw compressors, such as the compressor disclosed in U.S. Patent No. 4,435,119, have been used industrially to provide compressed air. This type of rotary screw compressor typically includes two rotors ' mounted in a working space which is defined by two end walls and a tube wall extending therebetween. The wall is in the shape of two crossed cylinders, each cylinder surrounding one of the rotors. Each rotor is provided with helically-extending blades and grooves with cross-engagement to establish an armband-shaped compression chamber. In these chambers, gasoline fluid is placed and compressed from the input channel to the output channel via a screw compressor. Each compressor chamber is connected to this input during the intake phase, undergoes a continuous decrease in volume during the compression phase, and is connected to the output during the exhaust phase. This type of rotary screw compressor is designed to control a single-phase oil film rotary screw compressor. The oil in the compressor can perform many functions. First of all, provide lubrication to prevent contact and wear of moving parts. The second 'oil acts as a sealant to fill all possible leak paths for compressed air to escape. The second 'acts as a heat conducting medium to absorb some compression heat. The oil is discharged from the compressor to the oil separation tank through compressed air, where the oil and air are separated. Although ‘some oil remains in the air, but it ’s only at the one-millionth level. It is known that these compressors can be controlled by electronic circuits. For example, it is disclosed in the US paper scale that the Chinese National Standard (CNS) is applied.

Explanation of the invention (>) National patent Nos. 4,336,001 and 4,227,862 show electronic control start and stop paths and bypass slide valve control to change the pressure of the compressor output to maintain the selected set point. U.S. Patent Nos. 4519,748, 4,516,914 and 4,548,549 and 4,609,329 show additional electronic control systems for compressors. However, these systems operate primarily designed for refrigerant compression. U.S. Patent No. 4,502,842 discloses a single electronic control system that can be connected to control several different size compressors. The system collects data about the operating characteristics of the controlled compressor during the calibration phase and then uses this information to load and unload the compressor during operation, maintaining a preset pressure that can be programmed and changed over time. The high and low pressure set points are programmed into the electronic control system and the compressor is selectively loaded and unloaded in a predetermined front-back relationship. However, this type of centralized master controller shows a single point of failure for all compressed air systems, and it lacks variability because the controller only provides limited options for control styles. U.S. Patent No. 4,33 5,582 shows that the screw compressor system is not used for unloading refrigeration systems. The sliding valve is connected so that it is automatically driven to the fully unloaded position when the compressor is stopped. This operation is achieved by air pressure rather than electronic control systems. The disclosure of U.S. Patent No. 5,713,724 is incorporated into a reference, which solves many control problems for this type of single-phase oil film rotary screw compressor by providing a complete and diverse solution to control and maintenance problems.

Description of the invention (h) Installation of facilities. Oil film screw compressor technology has been successfully used for many years. However, the demand for oil film form of this technology has become more common. Oil-free compressors can provide clean air. Only the water vapor component is required to be removed in order to use the compressed air in many sensitive devices. Because the EPA has been actively working to remove any pollutants from the environment during the manufacturing process, its oil-free compressor can provide no pollution oil Air. As known, some level (at least a small amount) of oil appears in the compressed air, and the compressed air oil is all known oil Membrane screw compressors. However, oil-free compressors produce compressed air without even a trace amount of oil in the air. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economics As known, oil-free screw compressors are essentially Complex machine. Because of the lack of lubricant in the compressor compression chamber, timing gears are used at the end of the rotor to prevent the rotors from rubbing against each other in oil-free compressors. To seal the small gaps that still exist after processing the compressor, the compression chamber All internal components must be surrounded by wearable materials and act as lubricants inside the compression chamber. Because no oil is present in the compression chamber of oil-free compressors, no oil can absorb the heat of compression, such as oil film compressors. No oil Or other heat-absorbing materials make oil-free compressors very susceptible to rapid, uncontrolled internal temperature increase. Further, if the oil-free compressors are two-stage compressors, the shrinking machine control must control both stages simultaneously. Control Two-stage compressors are very similar to controlling two individual single-stage compressors. The two-stage compressor or oil-free two-stage compressor network requires more complex control methods than the control of a single ® compressor or a single-stage compressor network, such as 6 paper standards applicable to Chinese National Standards (CNS) Eighty-four grid (210X2W public office) Staff of the Central Standards Bureau of the Ministry of Economic Affairs of the People's Republic of China 482878 5. V. Description of Invention (4) Disclosed in US Patent No. 5,713,724. Oil-free two-stage compressor β is unloaded differently at each stage Designed in other two-stage compressors. The reason for the unloading stage is to achieve the lowest unloading horsepower. By unloading two 1-stages instead of just the first stage, unless the control method is fully advanced to detect Measure or predict damage conditions and shut down the compressor before compressor damage occurs. The risk of compressor damage causing significant compressor damage is significantly increased. For example, there are many damage modes / conditions that cause severe compressor damage if they are not detected or predicted in real time. Such conditions are if one of the unloading valves fails to operate due to a condition such as electrical or mechanical damage. An alternative condition is if one of the discharge valves fails to operate due to electrical or mechanical damage and causes damage to the compressor. There are still other compressor damage modes that will occur if cooling system damage occurs. However, another compressor damage mode will occur if the oil pressure of the oil-free compressor is used to lubricate the bearings and gears below the minimum pressure. Another compressor failure mode will occur if the inter-stage pressure between two-stage compressor stages is outside the normal operating parameters for the compressor. Because the pressure changes during this stage, depending on whether the compressor is in a loaded or unloaded state, a control must decide whether the pressure between stages is acceptable based on the state of the compressor to continue operation or the compressor must be stopped to avoid damaging the compressor. Therefore, there is a need for electronic control systems and control methods for overturning / controlling one or more oil-free two-stage compressors. Such systems and methods should control each stage of an oil-free two-stage compressor. Such systems and methods should provide immediate predictions and / or predictions of damage patterns / conditions, which lead to severe compression-7 ~ Paper Waves are suitable for China National Standard (C: NS) A4AL grid (210 x 297 public places (please (Read the precautions before filling in this page)

Description of the invention (9) Like the POWER $ YNC® control system, the present invention is used to control a screw air compressor. The POWERSYNC control system 52 controls the compressor assembly 50, which is based on temperature and pressure measurements at necessary locations. The POWERSYNC ^ n control system 52 uses a modified microprocessor board. This board is used in the POWER $ YNC® control system with a daughter card to operatively connect to the main circuit board for determining the need to effectively control more complex oil-free Over-temperature and pressure input of the stage compressor 50. The POWERSYNC® Π control system 52 uses the same relay panel and display / keypad, such as those used in the POWER $ YNC® control system. However, a new warning circuit board is designed to handle the dense warning pattern of this compressor assembly, as described in detail below. The POWER $ YNC® Π control system 52 also has a form system similar to the POWER $ YNC⑧ control system, but displays more information than the POWER $ YNC® control system. The nature of the design difference between the compressors is that oil-free compressor components are the opposite of oil film compressors and require different types of control methods. Printed by the Consumers' Association of the Ministry of Economic Affairs, F. Cooperative. As mentioned above, this POWERSYNC® control system is designed to control a single-stage oil film rotary screw compressor or a network of several single-stage oil film rotary screw compressors. Many goals are achieved in this type of compressor oil. First, the oil provides lubrication to prevent contact and wear of moving parts of the compressor. Second, the oil acts as a sealant to fill all the possible escape paths of the compressed air through the turning screws. Third, the oil acts as a heat transfer medium to absorb some of the heat from the air compression. In an oil film compressor, the oil is discharged from a compressor having compressed air to an oil separation tank, where the oil is removed from the air. Although the residual oil is in compressed air, it is only at the level of one millionth. ______ 12 Wood paper scale is applicable to Chinese national standard (CNS) / \ 4 is now (210X 29? Public Office) '482878 Λ? ----- 一 _ Η7' .----------- ------------ V. Description of the invention (, C) The two-stage oil-free compressor assembly 50 is basically two compressors driven by an input shaft. The discharge from the compressor 54 is fed to the input port of the second compressor 56. Oil is not used inside the air compression chamber of the oil-free compressor assembly 50 because the moving elements of each compressor are covered with anti-wear materials, such as polytetrafluoroethylene (FEP), which is also well known

Telford. Because there is no oil to absorb any heat generated by the air compression of this type of compressor assembly, the air discharge temperature is higher than the air discharge temperature of the oil film compressor. There is also no separation tank because there is no oil separation from the air. Controlling a two-stage compressor is partly the same as controlling two separate compressors. The big difference between the POWERSYNC® control system and the POWERSYNC® control system 52 requires controlling not only one stage, but two compressor stages. And because the two-stage compressor is an oil-free compressor assembly 50, the compressor is more complicated than a standard single-stage oil film screw compressor. The Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs printed the POWER $ YNC®n control system 52 of the present invention to measure the discharge temperatures from the two compressors 54, 56 at 58 and 60, and the inlet temperature to the 62nd Stage 56 and compressor component discharge temperature (not shown). These temperatures are more important for the effective operation of oil-free two-stage compressor components than oil-film single-stage compressors because these temperatures are typically at higher levels than standard oil-film compressors and these temperatures are subject to more rapid changes. If any of these temperature rises exceed the limit, such as limited to the manufacturing setting sheet, which is not visible to the user, and can be set to an appropriate number, for example, the exhaust gas system is typically set to about 435 degrees Fahrenheit (435T) with input temperature To the second stage of the compressor and the discharge temperature of the compressor assembly is ________13 This paper size applies the Chinese National Standard (CNS) Λ4 specification (210X297 public place) " 482878 V. Description of the invention (, 丨) Set to approximately 120 degrees Fahrenheit ( 120 ° F), the POWER $ YNC®n control system 52 shuts down the compressor assembly. After the compressor assembly is shut down, the POWER $ YNC®n control system 52 will record the four measured temperatures used to shut down the compressor assembly, and the time and date when the shutdown occurred. The POWER $ YNC®n control system 52 has a POWER $ YNC® control system which is more intensive warning pattern and will indicate where the pattern occurs during shutdown. The more intensive warning pattern is used to very quickly indicate that a major shutdown has occurred without the operator needing to read the displayed message on the LCD screen. Because of the higher temperature of the oil-free compressor assembly 50, a cooler 70 for inter-stage air is required. During this stage, air is discharged from the first-stage compressor 54 to the input port of the second compressor 56. Because the catastrophic damage of the cooler 70 will block the voltage of the air flow, the POWER $ YNC®n control system 52 measures the discharge of the first-stage compressor whose air pressure is 72. If the pressure rise during this period exceeds the set limit of approximately 50 psi, the POWERSYNC®]! Will stop the compressor assembly. Printed by the Consumer Cooperative of the Central Standards and Leather Bureau of the Ministry of Economy. The cooler 74 is positioned at the discharge of the second compressor 56. Because the devastating damage of the cooler 70 will block the voltage of the air flow, the POWER $ YNC® Π control system 52 measures the emissions of the second-stage compressor 56 at a pressure of 76. If the airflow is blocked and the air pressure rises to an unsafe limit for a model of a high pressure compressor assembly at or above 142 psi, the POWERSYNC control system 52 will stop the compressor assembly 50. The POWER $ YNC®n control system 52 will stop the compressor assembly 50 if the compressor assembly is a standard pressure model and if the air pressure rises to an unsafe limit for approximately or exceeding 1 Upsi. _______ 14 CNS Λ4 & grid (21Gx;: 97); '-482878 V. Description of the invention ((2) When the oil-free compressor assembly 50 is designed to provide oil-free compressed air, With a compression chamber that is partially isolated from the compressed air at each compression stage, it requires lubricant. Because of this lubricant, the POWER $ YNC®n control system 52 measures oil pressure at 78 oil-free compressor components. When POWERSYNC® The control system does not measure the oil pressure in a single-stage air compressor. The oil pressure loss in a two-stage compressor assembly 50 can cause a rapid rise in the bearing temperature of the compressor. If the oil pressure falls below a predetermined limit, POWERSYNC® The control system 52 will stop the compressor assembly before bearing damage occurs. The POWERSYNC ^ n control system 52 also measures the pressure and temperature, after the second stage cooler 74. This pressure and temperature is called the component discharge pressure and discharge Temperature. The component discharge pressure is used to determine when to unload and load the two compressors. The component discharge temperature is conveniently displayed so that the end user can easily know that the pressure is leaving The air temperature of the engine components. If the component discharge temperature or pressure exceeds a predetermined limit, the POWERSYNC® !! control system 52 will stop the compressor components. The Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs will print two of the control systems 52 used in the present invention. The stage compressor assembly, 50 is different from any other two stage compressor assembly currently available if the assembly is designed to allow each stage to be unloaded. The current two stage compressor assembly is well known and available by the inventors It is only designed to unload the first stage. Only unloading the first stage works by shutting off the air flow to the first stage compressor and then seeking the second stage. The disadvantage of this method is that it still has a load on the compressor because The built-in compression ratio. The oil-free two-stage compressor assembly 50 of the present invention uses a poppet valve technology with a single poppet valve that is placed at each stage for 5-756 emissions, such as the following will be ________ · 15 (CNS) (210λ : TΓ ^-; "-2 8 4 A 7 _____ 1Γ *** * 一 _ 丨 _ One —- ^--— — V. Explanation of the invention (!,) The interpreter. Used in this Ming Zhi's poppet valve technology is commonly assigned to US Patent No. 5,556,271, the disclosure of which is incorporated in the reference. The poppet valve in this design destroys the compression ratio when the valve is opened. The POWER $ YNC®n control system 52 series Designed to unload two phases simultaneously. Specifically, POWER $ YNC®n control system 52 is unloaded simultaneously when the component pressure reaches the unloading point. When unloaded, the POWER $ YNC®n control system 52 is turned on A solenoid valve is used to unload any trapped pressure in the inter-stage tube. When the inter-stage pressure drops to a specified level, the pneumatic discharge valve discharged in the second stage is triggered to open. The inter-stage pressure and any trapped pressure are discharged in the second stage. When uninstalled. The component inspection valve isolates the compressor component from the end-user compressed air system. This unloading process reduces the unloading horsepower of the compressor components to an absolute minimum (or only approximately equal to the mechanical loss). Printed by the staff of the China Standards Bureau of the Ministry of Economic Affairs and the cooperative. When the component pressure (end-user system pressure) drops at the load pressure point, the pressure converter detects the drop at the component check valve and controls the compressor below the system load. For the first and second stage poppet valves are closed simultaneously. The inter-stage discharge valve is closed and the inter-stage pressure starts to rise. The pressure signal from the pressure drop between the stages triggers the two pneumatic exhaust valves to close at the set pressure level and the air pressure is established at the second stage exhaust valves until any rear pressure is overcome at the component inspection valve. At this point, compressed air is passed into the end-user compressed air system. This load method g is not the same as any used in a single-stage compressor and is not the same as any POWERSYNC ^ n control system applied to a single-stage compressor. The two-stage oil-free compressor assembly used in the present invention is not part of the stomach _ 16 This paper size applies to the Chinese National Standard (CNS) Λ4 specification (2 丨 0x2W) 482878 V. Description of the invention (μ) The compressor assembly is included. Oil-free shrink units are either fully loaded or completely unloaded. In contrast, controlled by this POWER $ YNC® control system is designed to be a partially loaded compressor. In other words, the compressor is not only designed to produce full load capacity, but some levels of air capacity are between full load and unloading. The POWER $ YNC®n control system 52 printed by the employee ’s consumer cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs uses pressure and temperature to determine whether the shutdown condition exists during the operation of the oil-free two-stage compressor assembly. In some cases, the pressure condition has been determined. This is a quick indication of emergency high temperature shutdown conditions than actual temperature measurement. For example, because air pressure is detected between the stages of the pipeline and pressure is discharged from the compressor components of the second stage, this type of measurement can conveniently determine whether there is a high incremental pressure over the second stage compressor. The high incremental pressure across the compressor of stage two will cause a very high temperature rise in the compressor of stage two. This temperature rise can occur very quickly and in some cases will occur too quickly for the current POWER $ YNC®n control system 52 temperature measurement circuit to detect and respond to this type of temperature rise. before. By measuring the critical pressure, it is possible to predict when high temperature conditions occur and stop the compressor assembly before any damage occurs. The POWER $ YNC® control system cannot use pressure to predict that a high temperature shutdown will occur in a single-stage compressor. The control system used in oil-free compressor components uses pressure and temperature sensors to detect real shutdown conditions or predict shutdown conditions, which are based on the operating status of the compressor components and the current temperature or pressure of the compressor. For example, it has been decided through experiments that if for some reason the input port of the compressor in stage two is less than the discharge pressure of the compressor in stage two, the excess _____ 17__ This paper size applies the Chinese National Standard (CNS) A4JI see the grid (210XM7 public V.) ~ 482878 V. Description of the invention (<) Allowable 値, then high temperature conditions will occur in the compressor of stage two and cause the compressor to capture. The pressure difference first occurs in this state and the control system expects damage based on the measured pressure difference data and stops the compressor assembly before phase two compressor damage can occur. The limit is established by calculating a number 値. This number is calculated by measuring the discharge pressure of the second stage compressor and the discharge pressure of the first stage compressor. When the second stage compressor discharge pressure is greater than about 80 psi (> 80 psi) and the first stage compressor discharge pressure is less than about 10 psi (< 10 psi) during about 10 seconds, the alarm is shaken and the controller will stop The compressor assembly. The control system then records the shutdown event in the non-volatile memory area and displays the reason for the shutdown on the LCD display to the compressor operator. Printed by the Central Standards Bureau of the Ministry of Economic Affairs and Consumer Cooperatives When other shutdown conditions found through experiments occur, if the compressor is cycled and unloaded too frequently. This condition may occur if the compressor is installed with insufficient air storage. Because the compressor assembly does not include a pump to separate oil from compressed air, and is an oil-free compressor assembly, the air storage jf is required to restrict circulation. The control system is not designed to stop the air compressor because of fast cycling, but the system does record the number of cycles per minute that occur. However, rapid cycling will cause high air temperature shutdowns of the compressor components under certain conditions, and this will not be avoided due to installation. However, if a high air temperature shutdown does occur, a record of compressor cycle conditions before the shutdown will be displayed to the compressor operator. Other shutdown conditions are low oil pressure, high air temperature from the first stage discharge, second stage output, second stage discharge or component discharge, high second stage discharge pressure, high component discharge pressure, and possible reverse motor overload_ ___ _ 18____ This paper size applies to Chinese National Standard (CNS) Λ4 specification (210X297 cm) 482878 V.

The compressor assembly 1002 is connected to a drive motor 100, which provides rotation to a compressor input shaft (not shown) and transmits rotations to gears (not shown) in turns. The compressor assembly 1002 begins to divert and air is drawn to the input filter 100A. The filter 100A provides protection from air contaminants from entering the compressor assembly 1002. The first stage compressor 102 compresses the air to about 30 psi. This compressed air is transferred from the first stage compressor 102 to the inter-stage line 104. Compressed air flows through line 104 to interstage cooler 106. The cooler 106 reduces the air temperature to about 300 degrees Fahrenheit (300 ° F). The cooler 106 is connected to the discharge of the first stage compressor 102 via a coupling plate 108. Printed by the staff of the Central Bureau of Standards of the Ministry of Economic Affairs and printed by cooperatives. Compressed air is sent via interstage cooler 106 to another interstage pipeline 112. This line 112 is connected to the dehydrator 110 via a connection plate 108A. The dehydrator 110 is connected to the inter-stage pipeline and is guided to the second-stage compressor 114 via the inter-stage cooler 106, which is also connected to the dehydrator 110 via the connection plate 108B. Any moisture collected in the compressor 102 from the first stage is collected and processed in the dehydrator 110. This type of processing is well known and well known to those skilled in the art. The compressed air is sent to the input of the second stage compressor 114. The first stage compressor 102 compresses the air by another approximately 70 psi, which raises the air to approximately 100 psi. The compressed air is transferred from the second-stage compressor Π4 to the second-stage compressor discharge pipe Π8. This pipe 118 is connected to another discharge pipe. ____19___ This paper scale is applicable to China's national standard (C: NS) A4ML grid (210X 297 public garbage) 482878 V.

The timer is labeled TR4 to be operatively positioned in the circuit and is operatively connected to a circuit with another timer labeled TR3. The coil is labeled CR3 for operative connection to timer TR3 and a set of connectors. When the compressor assembly is shut down and the solenoid valve SP5 is normally closed, the energy is reduced without water flow. For the flow switch to observe any water flow, the flow switch current must delay the signal that the solenoid valve SP5 is stopped. This is achieved by using a timer to activate relay CR3, which allows the compressor assembly to start. When the compressor assembly started, the water shutoff valve was activated and opened so that water flowed to the compressor assembly. At this point, the timer is suspended and CR3 is released. When CR3 is released, it should have water flow. If there is no water flow, CR4 connected to the flow switch FS1 will be turned on. The CR4 relay was added to the circuit because the connector provided by the flow switch FS1 was not sufficiently heavy to carry the current load. The advantage of the next two steps is that a set of 32 paper sheets are normally sealed. The Chinese paper standard (CNS) A4ML grid (210X:> 7) is used. 482878 5.
