Description

Engine control device for controlling flow rate, head-adjusting type industrial engine pump (including fire engine pump) and engine pump {omitted}

In the present invention, a cruise control system is added to a general engine controller to memorize the number of revolutions of the engine with a switch incorporated in the engine control device. In addition to displaying the number of revolutions of the engine through the engine rpm sensor And monitors the number of revolutions. When the number of revolutions changes, the actuator connected to the accelerator is driven to adjust the number of revolutions so as to suppress changes in the number of revolutions of the pump and the engine, And relates to utilizing and controlling the performance of the engine as the power varies with the number of revolutions.

In the present invention, when the engine is running, the engine is stopped at the number of revolutions at which the engine can start at a speed that is most commensurate with the characteristic of the engine (the position of the switch can be adjusted) If the accelerator has an engine stop function although it depends on the type of the engine, the actuator that controls the accelerator is driven in the reverse direction to stop the engine (selectable) and has the function of returning the accelerator by the rotation speed In particular, it is possible to adjust the position of the switch in accordance with the characteristics of the engine (swing angle and shape of the accelerator) used as a switch built in the actuator (position memory in the case of a small servomotor) , An engine for controlling a head-adjusting industrial engine pump (including a fire engine pump) and an engine pump It is a tube device in Troll

In addition, the present invention provides a safety mode function to prevent a serious accident by giving the engine control device a function of returning to the automatic mode in the manual mode in which an artificial mistake is compensated after the manual operation is performed. The battery is charged to the battery by using the generator of the engine itself, and when the battery is stored for a long time, 220V power supply is connected in order to discharge the battery, so that the battery can be charged by using the built-in charger.

The number of revolutions of the engine used as the power source in the industrial engine pump including the engine pump for the firepower in the presently used engine pump is selected based on the customized specification (design specification of the consumer, hereinafter referred to as the customized specification), and approximately 1800 rpm Is set in. It designs the pump based on the number of revolutions of the four-pole motor and applies the pump used in the motor to the engine as it is.

The characteristics of the pump are characterized by increasing the flow rate and head by increasing the number of revolutions. As shown in Fig . 10 diesel engine performance curve and Fig. 11 gasoline engine performance curve, when the number of revolutions of the engine increases, .

Using these characteristics, if the flow rate and head (pump: pressure / kg / cm ² in units expressed by m in units expressed in meters) at 1800 rpm are selected and the number of revolutions is increased, a is exerted

Experiments were carried out to confirm the above contents, as shown in FIG . 7 and FIG .

All piping design and withstand-pressure tests currently carried out are carried out at 150% of the actual working pressure and are specified in the KS and ASME standards.

Particularly, in the Fire Service Act, the cut-off (maximum) pressure is within 140% of the operating pressure, and 150% of the operating flow is specified as 65% or more of the operating pressure.

According to the present invention, the engine is operated in a section having good engine efficiency according to the specifications and the specifications of the engine, and the engine speed is changed by adjusting the accelerator of the engine with one small pump and a small engine corresponding thereto, , The number of revolutions of the engine corresponding to the pump performance of the next higher level is stored in the engine control device and the engine used as the power source changes in accordance with the change of the power The actuator connected to the accelerator is used to precisely control the accelerator to prevent the rotation of the engine and the pump from being changed, thereby suppressing the change in pressure due to the change in the flow rate as shown in Fig. 9 , Saving.

Until now, there has been no way to charge the battery of the industrial engine pump necessary for starting the engine and driving the engine control device without connecting the 220V power source, so that the battery is replaced when the battery is discharged. However, When the engine pump is used in a place where there is no battery, the generator is installed in the engine to enable the battery to be charged through self-power generation during the pump operation. In case of storage or fire pump, Thereby preventing the battery from being discharged.

Especially, in the case of a fire engine pump, it is necessary to carry out a test operation regularly. Since current engine controller is inconvenient to automatically switch by using a changeover switch or a toggle switch, it is possible to prevent a serious accident However, in the present invention, a safety mode function for automatically switching to standby after a predetermined period of time is prepared in preparation for a case in which no automatic artificially switching is performed after the operation test.

Prior Art 20-2007-0004199 "Control device for engine pump for fire control" is a device for manually controlling the number of revolutions of the engine on the front surface of the case,

As a prior art, there is a "fire engine pump" 20-2013-0005670, the engine speed is controlled in the same manner as the above-mentioned prior art, the engine speed is controlled at 1800-2000 RPM, The speed control lever is controlled by simply feeding back the rotation speed of the engine to the rotation speed of the engine to control the speed control lever according to the change in the rotation speed of the engine. This is a simple function device that causes the idle revolving speed to start the operation at the set number of revolutions after starting and to cause the speed regulating lever to move to the initial position after stopping.

Some of the technical constructions of the present invention have similar functions to those of the prior art, but have a totally different structure, so that there are remarkably different differences. The prior art is limited to fire extinguishing only, has no utility in industrial use, The speed control means is very difficult and difficult to apply due to a small space to be attached to the actual engine. When the speed control means is caused to move the speed control lever to the initial position after stopping the engine, If stopped, a large amount of fuel is injected and the start-up becomes very low.

In particular, the fire engine pump is required to be tested by the Fire Service Law to check the engine pump periodically for abnormalities. However, since it is not a daily repetition, it is not possible to prevent a very serious accident in advance if the test does not switch automatically after a while.

Currently, the industrial engine pump that is manufactured has self-power generation function but there is no power charging function when it is stored for a long time, and the problem of replacing the battery frequently occurs.

In addition, due to excessive competition of the engine pump, further cost reduction can not be achieved. In the market, except for performance and quality, the product is selected only for the price. Cost reduction is required.

If the standard specifications of the pump are different for each manufacturer, and there are standard specifications for each pump, and if the consumer requires any intermediate specifications that are not standard specifications, the pump should be disassembled to reduce the outer diameter of the impeller to the dimensions It is necessary to reassemble the product after it is cut and check it by the quality control department. Therefore, the manufacturer is complaining about the delivery time and cost as the consumer as the manufacturer.

The number of revolutions of the engine used as a power source is selected based on the number of revolutions of the motor in a place where the currently used power electricity can not be used (a place where a pump operated by a motor can not be used) or an emergency engine pump including a fire engine pump And it is set at about 1800 rpm. However, it is impossible to adjust the increase or decrease of fuel by fixing the accelerator according to the customized specifications. As shown in Table 1 of FIG. 7 , according to the flow rate and head of the pump, as severe a revolution speed change this number is the actual circumstances that problems can occur, increasing the number of revolutions was a change in the flow rate and the head seam as shown in the upper and tea, make the performance of the upper pump results also table of Figure 82 of an engine according to the engine .

In addition, all piping design and withstand pressure tests currently carried out are carried out at 150% of actual operating pressure as specified in KS and ASME standards. Particularly in the Fire Service Act, the cut-off (maximum) pressure is within 140% And 150% of the flow rate is set to be 65% or more of the operating pressure, and a pressure more than necessary is applied to the pipe due to corrosion of the pipe due to use for a long time, leading to breakage of the pipe

The present invention relates to an industrial engine pump (including an engine-driven pump) capable of controlling the flow rate and a headlift, and a control system that minimizes the change of the rotational speed due to the change of the power according to the change of the flow rate (cruise control system) will be.

Generally used pumps can be used, but general industrial (including fire fighting) pumps are designed at 1800 rpm, which can cause danger in high-speed rotation. With the development of pumps that can withstand high-speed rotation, By using the effect of large pump and large power by small engine, it is possible to reduce cost and reduce installation area, and it is possible to reduce the cost of the user Can be saved.

3-phase 3-wire or 3-phase 4-wire power input and auxiliary pump motor power output unit included in general fire engine control unit are basically operated by receiving signals from a fire receiver, In addition to being able to charge the battery, it is also equipped with a 220V power supply to charge the engine as in a fire engine pump,

It can be applied to all engines with an actuator fixing bracket and an accelerator connector manufactured according to the engine type by directly driving the accelerator. If the accelerator has an engine stop function according to the engine type, it is designed to stop the engine by driving the actuator in the reverse direction .

The present invention uses a tact switch (tact switch) on the front surface of the engine control device, which is an important safety concern for a fire engine pump, and has an engine control device that corrects a human error by itself .

In order to solve the above-described problems, the present invention provides an actuator and an rpm sensor, an arbitrary number of revolutions, and an engine control device for maintaining a predetermined number of revolutions, thereby achieving the same effect as a pump operated by a motor. By increasing or decreasing the number of revolutions, the flow rate and head can be diversified.

Regardless of the size of the motor, the number of revolutions is determined according to the number of poles. The number of revolutions is determined according to the number of poles. The quadrupole motors are determined at 1800 rpm and the bipolar motors are determined at 3600 rpm. . On the other hand, the engine can be freely controlled, and the number of revolutions, depending on the type of engine, but the difference is usually in the case of diesel engines 2000~2500 rpm (see Fig. 10), in the case of a gasoline engine 2500~3000 rpm (see Fig. 11 ), And the power is also increased when the number of revolutions is increased.

According to the above contents, the number of revolutions of the engine is increased or decreased, so that the performance of various kinds of pumps can be exhibited by one kind of pump. Especially, among the types of pumps used in the fire pump, If the number of revolutions is increased for a pump having a smaller number of stages, it is possible to realize the pump performance of the next higher level.

For example, when a single stage three-stage pump (MV80-3S) is rotated at a standard speed (1750 rpm) in a multi-step route pump, the standard performance flow rate is 0.6 m ³ / min and the head is 54 m (MV80 - 4S) performance (flow rate 0.6 m3 / min, heading 72 m) when rotated at 1975 rpm and rotating at 2310 rpm, the performance of the nominal 80 stage 5 stage (MV80-5S) (Flow rate: 0.6 m3 / min, heading: 90 m). When the rotor is rotated at 2420 rpm, the performance (flow rate: 0.6 m3 / min, Performance (flow rate of 1.0 m3 / min, pressure of 45 m) of stage (MV100-2S) and performance of 22 stages (flow rate of 1.0 m3 / min, 67 m of head) .

In other words, the engine pump EMV80-3S can be used with one engine pump to implement the specifications of the six pumps, and each pump has its own standard specification (each manufacturer has its own standard specification slightly different) It is not necessary to disassemble the pump and cut the outer diameter of the impeller into the dimensions calculated in the design, and reassemble it. In the engine pump of the present invention, the engine speed can be adjusted by the number of revolutions of the engine, the manufacturer can supply the standard pump and adjust the engine speed to meet the specification, It is very economical and quick because it can be widened. Because it uses a small engine and a small pump, cost reduction can be achieved. Since the installation area is small, the construction cost and maintenance cost can be reduced . It is the purpose of the invention to make it possible.

As described above, when the engine control device for maintaining the engine speed according to the actuator, the engine rpm sensor, the engine speed setting, and the engine speed setting are used, the engine rotation It is possible to prevent the change of the number, to operate in the rotation section with good engine efficiency, and to use the specifications of the upper or lower engine pump with one small engine pump, Can be attributed to the reduction of the operating costs used in the system.

All piping design and withstand-pressure tests are carried out at 150% of the actual operating pressure as specified in the KS and ASME standards. Particularly, in the Fire Protection Act, the cut-off (maximum) pressure is within 140% Of the operating pressure is specified to be more than 65% of the operating pressure at 150% of the operating pressure. As a result of long period of use, more than necessary pressure is applied to the piping due to corrosion of the piping.

When the engine pump is operated in a place where there is no power source It is possible to charge the battery by self-power generation by attaching engine generator which is an indispensable device in industrial engine pump, and it is built in engine control device in storage and standby state. 220V power supply through the charger to prevent charging and discharging the battery,

When the engine is stopped, the actuator is configured so that the engine stops at a speed at which the engine starts at a good starting speed in preparation for the next start. This makes it possible to start the engine at the highest rotation speed (which varies depending on the characteristics of the engine) Lt; / RTI >

Although there is a difference depending on the type of the engine, it has a function of stopping the engine by driving the actuator for controlling the accelerator in the reverse direction, and returning to the rotation speed at which the engine is started.

Especially, in the case of fire engine pump, it is necessary to carry out trial operation periodically (Fire Service Law is obligatory), current engine controller is inconvenient to switch automatically by artificially using switch or toggle switch, However, according to the present invention, there is provided a safety mode function that automatically switches to standby mode after a predetermined time by itself when the automatic test mode is not switched after the operation test, thereby preventing unexpected unexpected accidents.

10 is a performance curve of a light oil engine provided by an engine manufacturer, and FIG. 11 is a performance curve of a gasoline engine provided by an engine manufacturer

The characteristics of the pump are characterized by increasing the flow rate and head by increasing the number of revolutions. Taking advantage of these characteristics, if the number of revolutions is increased by using the small pump 2-2, the small pump 2-2 will exhibit the upper or lower pump performance.

As shown in Fig. 10 diesel engine performance curve and Fig. 11 gasoline engine performance curve, when the number of revolutions of the engine increases, the power also increases.

By using the above characteristics, the small-sized engine pump connected to the small-sized pump 2-2 and the small-sized engine 2-1 exhibits the performance of high specification of large flow rate and high heading.

The general pump can be used, but the ordinary pump is designed at 1800RPM, which can cause danger in high-speed rotation. Therefore, the small pump (2-2) is designed using a pump (2-2) And the corresponding small-sized engine 2-1. In consideration of the characteristics of the engine 2-1, the engine 2-1 is operated at 1800-2500 rpm for the diesel engine and 2000-3000 rpm for the gasoline engine The efficiency of the pump 2-2 can be increased and the engine can be operated in a section with high efficiency.

As an industrial engine pump including a fire engine pump, it includes general functions such as a three-phase power input, an auxiliary pump motor output, and a power output, which are included in a fire control engine control device 1-1 as shown in FIG. Not only is it possible to charge the battery while the engine pump is operating by installing the generator 1-4, as well as charging the 220V power supply as in the case of the fire engine pump,

The present invention is characterized in that an actuator 1-2 with an accelerator connector 1-23 directly drives an accelerator (not shown, shape and swing angle differs for each type of engine for each engine manufacturer) The actuator fixing bracket 1-25 and the accelerator connector 1-23 manufactured in accordance with the type of the engine 2-1 can easily be mounted to any engine pump and the actuator 1-2 So as to stop the engine 2-1.

When the operation signal of the engine 2-1 is inputted to the engine control device 1-1 from the fire receiving unit by using the engine pump operation signal or manually by using the switch on the front surface of the engine control device 1-1, The electric power of the battery is supplied to the fuel pump or the fuel supply valve 1-5 (some engines are not provided with the fuel pump or the fuel supply valve according to the engine type) attached to the engine 2-1, After the power is supplied to the preheating plug 1-6 for a predetermined period of time (limited to the light oil engine), the engine 2-1 is started by applying power to the engine starting motor 1-7.

When the engine 2-1 is started, the engine control device 1-1 applies voltage and current to the small DC motor or the small servomotor 1-21 of the actuator 1-2 and supplies the small DC motor or the small servo motor 1-21, An accelerator connector 1-23 connected to the output shaft of the speed reducer 1-22 (an accelerator (not shown) of the engine (not shown) is connected to the output shaft of the speed reducer 1-22 by rotating the gear connected to the inside of the speed reducer 1-22, ), And an accelerator (not shown) connected to the accelerator connector 1-23 operates.

When the accelerator is that the engine operation (2-1) is the acceleration is a switch mounted on the other end of the accelerator connector (1-23) of the reducer (1-22) sensing plate (1-24) is as illustrated in Figure 3 to help " A "position to the" B "side, and the number of revolutions of the engine 2-1 increases.

The engine rpm sensor 1-3 detects the number of revolutions of the engine 2-1 and transmits the number of revolutions of the engine to the engine control device 1-1. ), The engine control device 1-1 compares the preset rotation speed with the preset rotation speed, applies a current and voltage to the small DC motor or the small servo motor 1-21 of the actuator 1-2, When the rotation speed is approached, the current and voltage are gradually reduced to a small DC motor or small servo motor 1-21 of the actuator 1-2 so that the set value can be reached precisely.

The accelerator maximum position switch 1-27 on the "B" side senses the maximum position of the accelerator (not shown). When the accelerator maximum position switch 1-27 is detected, Stop.

When the discharge valve 4-3 of FIG. 6 is opened, more flow rate is discharged from the pump 2-2, the head is lowered, and the pump 2-2 requires more power. As a result, the number of revolutions of the engine 2-1 is reduced and the number of revolutions of the engine 2-1 sensed by the engine rpm sensor 1-3 is sent to the engine control device 1-1, The engine control device 1-1 applies a small DC motor or small servomotor 1-21 voltage and current of the actuator 1-2 so that the small DC motor or the small servomotor 1-21 performs forward rotation The accelerator connector 1-23 connected to the speed reducer 1-22 is rotated forward and the accelerator connected to the accelerator connector 1-23 is rotated forward to compensate the rotation speed of the engine 2-1.

When the check valve 4-3 of FIG. 6 is locked, the flow rate discharged from the pump 2-2 decreases and the pressure increases. The power of the pump 2-2 is reduced. As the load decreases, the number of revolutions of the engine 2-1 increases, so that the engine control device 1-1 outputs a reverse voltage and a reverse voltage to the small DC motor or small servomotor 1-21 of the actuator 1-2, The small DC motor or the small servomotor 1-21 rotates in the reverse direction to move the accelerator (not shown) in the "A" -direction so as to lower the rotation speed of the engine 2-1.

The engine control device 1-1 controls the operation of the small DC motor or the small servo motor 1 of the actuator 1-2 according to the amount close to the set number of revolutions -21) is characterized by P control (Proportional Control) or PID control (Integral and Derivative Control) which enables to reach the set value precisely while gradually reducing current and voltage.

The engine control device 1-1 has a selection switch incorporated therein for selecting the type of the engine 2-1 when the engine 2-1 is stopped,

Applied to the engine (2-1) the accelerator to stop the function to drive the switch in a direction opposite to emergencies or actuator (1-2) in a standby state for a long time to start-up position at which the well when the start-up in Figure 3, if no detection plate (Gasoline or light oil) is appropriately placed in the cylinder of the engine 2-1 (when the fuel is in an excessive state) : When knocking phenomenon occurs, startability is not good, when the engine is running at the lowest RPM (IDLING RPM): It does not start well when stored for a long time] After powering up, the power supplied to the fuel pump or the fuel supply pump Thereby stopping the engine 2-1,

When the applied engine 2-1 has a stop function in the accelerator, it is set as a selection switch in the engine control device 1-1, and an actuator 1-2 connected to an accelerator (not shown) The switch detection plate 1-24 is moved in the "C" direction through the "A", the engine start position switch 1-26 is turned off after the engine is turned on, and the engine stop position switch 1-28 are turned ON and when the engine 2-1 is stopped, the engine rpm sensor 1-3 confirms that the engine 2-1 is completely stopped and then the engine control device 1- 1 shifts the small detecting DC motor or the small servomotor 1-21 of the actuator 1-2 to rotate the switch detecting plate 1-24 through the "A" to the "B" When the position switch 1-28 is turned OFF, the engine start position switch 1-26 is turned ON and then turned OFF, To the position (1-26) to stop when the ON and stops at the position where the well is started in the stand-by state of the emergency information or a long period of time. This allows the accelerator (not shown) to always start the engine in the correct position.

The industrial engine pump must be capable of charging during operation. In the case of fire engine pump, it is always possible to charge by connecting the power source. However, when the power is not used, it can not be used because the battery is discharged.

Therefore, when the engine 2-1 is activated by installing the generator 1-4 in the engine 2-1, the generator 2-1 is charged with electricity by generating electricity, and when storing the battery for a long time, So that the battery can be charged.

The safety mode function is the most important function in the fire engine pump. In the present engine controller, the switches used in the front side are artificially operated by using physical switches such as a changeover switch and a toggle switch. This can cause a big problem in safety due to human error.

Programmable Read Only Memory (PROM) 1 of the engine control device 1-1 is connected to the front surface of the engine control device 1-1 of the present invention by using a tact switch (micro pushbutton switch) ) Or EPROM (Erasable Programmable Read Only Memory), and it automatically switches itself when there is no manual operation for a certain period of time by inputting an automatic switching program, thereby preventing artificial mistakes and serious accidents A safety mode function is installed and a hidden switch is set by using the switches located on the front side of the engine control device 1-1 and the important switch is set by pressing the hidden switch.

The Hidden Switch is a switch that is used when a factory inputs various characteristics such as the type of the engine 2-1, the manufacturer of the engine, and the type of the pump 2-2. It is a special switch function which enables to set the switch and time in the internal program so that important settings can not be accessed, and to switch to the setting mode by pressing the set 2 ~ 3 buttons for more than a few seconds
