Description

[0001] The present invention relates to a control system for water hammer prevention,

More particularly, the present invention relates to a water hammer prevention control system, and more particularly, to a water hammer prevention control system in which impurities such as oil are fed through a high-pressure compressed air generated by an air compressor and then pressurized to adjust the level of water contained in the air chamber. Pressure compressed air so as to supply the compressed air generated by compression in the air compressor to the air chamber so that impurities are filtered and pressurized in the air filter to be delivered to the air chamber by a software algorithm To a water shock control system that can quickly respond to a water impact.

Generally, in a water piping system, in case of a sudden stop of a pump or a sudden closing of a valve, a transient condition occurs in which the flow rate and the pressure suddenly change. Such a phenomenon is called a water hammer or a water hammer phenomenon, Quot; As a result of this water shock phenomenon, the pressure in the piping rapidly increases due to the shape of the pipe due to the propagation of the pressure wave due to a sudden flow change in the pipe, or the pressure in the pipe falls below the saturated vapor pressure of the water, And may cause collapse or breakage of the pipe due to shock waves during the process of column separation & return.

The water hammer phenomenon is caused by the sudden rise of the water pressure when the water flowing in the pipe is suddenly blocked by the valve, resulting in the sagging pressure, which causes the water hammer to reciprocate in the pipe, resulting in noise and vibration . The generated noise and vibration are transmitted to the surrounding structure through the pipe, causing the water hammer phenomenon, which is the generation of the shock wave in the pipe. Particularly in the case where a liquid is supplied in a limited cross section such as a pipe or the like, the problem of this change in pressure becomes more serious. When there is a change in the flow rate, such as suddenly closing the valve of the pipe or stopping the pump, the kinetic energy of the fluid changes into pressure energy, so that this pressure change is transmitted at the propagation velocity. When this pressure wave returns, the sign of the pressure is reversed, and it continues to reciprocate in the channel, causing the water hammer action.

In general, the type of water impact (or water hammer) phenomenon can be classified according to the form in which the pressure is abruptly changed at any point in the piping system. That is, it can be classified into the case where the pressure in the pipe rises sharply (high pressure) and the case where the pressure rapidly decreases (low pressure). In order to prevent a high pressure in the piping, a relief valve, a safety valve or a dash-port check valve is installed to discharge the fluid from the piping system. In order to prevent low pressure, a method of introducing air or fluid into a piping relation is used by using an air / vacuum valve (Air / Vaccuum Valve) or a one way surge tank, A sealed air chamber is used as a device for preventing the above problems.

Accordingly, the applicant of the present invention intends to propose a system for automatically recognizing the water hammer phenomenon through the water hammer control to reduce the water hammer phenomenon through the programmed control logic to control the water hammer prevention.

7 is a block diagram showing the internal configuration of the drive control logic in-set unit 550 of the water impact prevention control system of the present invention. The drive control logic internal setting unit 560 mainly includes a water level adjustment setting unit 551, A setting unit 552, a water hammer setting unit 553, a valve setting unit 554, a compressor setting unit 555, and a light setting unit 556.

In the water level setting of the water level adjustment setting unit 551, a set value or a bracket value is displayed as a default value, and the detailed information set through the water level adjustment setting unit is as follows.

(1) Target operating level (L3, 050%): This item is set so that the water level in the air chamber can be kept constant. It includes air compressors (OUT 01 and 02) and air supply solenoid valve (OUT 05) (OUT 06) is stopped.

The output of all the air compressors OUT 01 and 02 and the air supply solenoid valve OUT 05 which are activated when the water level in the air chamber 100 reaches the set value of the " (OFF) the output of the "air exhaust solenoid valve (OUT 06)".

(2) Main compressor operating level (L4, 055%): When the water level in the air chamber rises to "2nd main compressor operating level", the first (leading) air compressor (OUT 01 or OUT 02) And stops the air compressor when "1.Drive target water level" is reached. When the air compressor starts to operate, if the "Solenoid Solenoid Valve (OUT 05)" is present, "Solenoid Solenoid Valve" is output (OPEN, ON). However, "OUT 05" is output only when "22. Supply solenoid valve (ON / OFF)" is "ON."

(3) Auxiliary Compressor Operation Level (L5, 065%): The air compressor is running, the air supply is insufficient or fault occurs, and the water level in the air chamber keeps rising. When the water level rises to "Auxiliary Compressor Operation Level", the additional auxiliary compressor is activated, and the water level in the air chamber is increased to "1. When the target operating level reaches "-1", the auxiliary compressor is stopped. (Two compressors operating at the same time)

(4) Primary air discharge level (L2-1, 045%): If the water level in the air chamber drops to "4.1 Air discharge level" for some reason, if the compressor is running, , 02) is forcibly stopped and "OPEN (ON)" and "CLOSE (OFF)" operations are intermittently repeated and the intermittent operation time interval is " Time "CLOSE (OFF) the" Air discharge solenoid valve (OUT 06) "when" 1.Drive level "is reached.

(5) Secondary air discharge level (L2-2, 040%): When the water level of the air chamber (100) is lower than the value set in "4.1 Air discharge level" If the air chamber level drops to the "5.2 air outlet level", if the compressor is running, the air compressor is forced to stop (OUT 01, 02) and the "OUT 06" OPEN (ON).

On the other hand, when the chamber water level rises to "3.1 air exhaust level: 45%", the "air discharge solenoid valve (OUT 06)", which was continuously operated, is changed between OPEN (ON) and CLOSE (OFF) 1. When reaching the target operating level "CLOSE (OFF) the air exhaust solenoid valve (OUT 06)".

(6) High water level alarm (L4, 090%): An alarm is generated when the water level in the air chamber rises above the "6. Water level alarm" ) And all set air compressors (OUT 01, 02) are automatically operated and save the data record. (OUT 13, 14) output stops when "3rd auxiliary compressor operation water level: 65%" is reached, and compressor output (OUT 13, 14) stops when it reaches "1st target operation water level".

(7) Lower limit water level alarm (L1, 010%): The water level in the air chamber is "7. Lower limit water level alarm: 10%" because of excessive air that can not prepare the water hammer due to input error or pressure change. (OUT 01, 02), stop all the compressors (OUT 01, 02) and output (OPEN, ON) the alarm output (OUT 13, 14) Save the data record. When the chamber water level rises to "4.1 Air outlet level: 45%", it changes OPEN (ON) / CLOSE (OFF) intermittently by operating the air discharge solenoid valve (OUT 06) continuously.

(OUT 13, 14) output is stopped when "5.2 discharge water level: 40%", and "OP 06" is closed (OFF) when "1.

(8) Excess air discharge level (LA, 020%): The water level in the air chamber drops to "8. Excess air discharge level" due to any abnormality or setting error, and the pressure in the air chamber is " . If it is smaller than the reference pressure deviation "or" 9. Reference standard pressure +10. Reference pressure deviation ", the alarm is generated (OUT 13, 14) and if there is an air compressor running, (OPEN, ON) of the "air discharge solenoid valve (OUT 06)" and stores the abnormal data. When the chamber water level rises to the "primary air discharge level", it changes OPEN (ON) / CLOSE (OFF) by the intermittent operation of the "air discharge solenoid valve (OUT 06) 40% ", the output of the alarms (OUT 13, 14) is stopped. When reaching the" 1st operating water level ", the air discharge solenoid valve (OUT 06) is CLOSE (OFF).

The pressure setting unit 552 is a pressure in which the operation standard pressure (5.0K) of the pump is normally operated. The pressure of the air chamber should be inputted not only at the level on the end view but also the actual pressure including the loss of the valve and the channel And input the value during the comprehensive operation. At this time, there may be a pressure deviation during the number of operation or sequential operation of the pump. In general, in the method of operating the most pumps, the value of "pump operation pressure = chamber pressure" is inputted.

(1) Reference pressure deviation (2.0K): This is the difference between the pressure at normal operation of the pump and the difference in pressure at the time of stoppage. It is recognized as normal operation within the pressure range of this value. Even if it is lowered, the "Air release valve (OUT 06)" will not operate. However, if the "11th water level correction stop time: 60 minutes" elapses, operate the "OUT 06" to adjust the chamber level to "1st target operating level".

If there are several pumps, input about 0.3 kg / cm ² is normally added to the value of "pump head-to-head pressure" in consideration of the difference in pressure fluctuation depending on the number of operations of each pump.

If the chamber level is below "8. Excess air exhaust level: 20%" and the chamber pressure is "9. Operating pressure (+) or (-) 10. Reference pressure deviation" "To discharge air.

(2) Water level correction delay time (60 minutes)

If the pressure in the air chamber is within the range of "9. Operating reference pressure-10. Reference pressure deviation", the "OUT 06" will not operate even if the water level is lowered. However, if the "11th water level correction stop time: 60 minutes" elapses after the water level is lowered, operate the "OUT 06" To adjust the water level.

(3) Stop Rate of Change (per second) (2%, 0.2K) (Continuously increasing and decreasing pressure) If the water level changes more than 2% per second or the pressure changes more than 0.2K per second The "air discharge solenoid valve (OUT 06)" and "air compressor (OUT 01, 02)" and "air supply valve (OUT 05)" do not output (ON).

That is, since the pump that is being operated is stopped and the water level changes, the solenoid valve and the compressor are not operated.

(4) Upper pressure alarm (09.5K): It is a value for monitoring when the pressure is increased due to input error of operation pressure or other device problem. It is larger than "9. Reference standard pressure +15. Enter a value greater than or equal to 0.5 K above the "Hydration Pressure Deviation") and do not operate if water hammer occurs. When the pressure in the air chamber rises above the value of "13. Upper limit pressure alarm: 9.5K", the alarm (OUT 13, 14) is generated and when the pressure drops to reach "9. Reference pressure + reference pressure deviation" Release the alarms (OUT 13, 14).

If the value of "6. High pressure alarm" is set to "0", the function will not be performed.

The upper limit pressure alarm setting value is larger than the "9. Operating standard pressure + 10. Water pressure deviation" value (minimum 0.5 kg / cm ² or more) .

(5) Lower limit pressure alarm (0.5K): When the pressure in the air chamber falls below "14.LOW LIMIT PRESSURE ALARM: 0.5K", alarm (OUT13, OUT14) When the pressure -10. Reference pressure deviation "value is reached, release the alarm.

The lower limit pressure alarm setting value is smaller than the value of "9. Operating standard pressure-10. Water pressure deviation" (minimum 0.5 kg / cm ² Or more), and if it is input more than this, it outputs a message "Setting error" and prevents input.

The water hammer occurrence determination unit 553 is a value for setting the water hammer recognition standard in the presence of pressure fluctuation in comparison with the water hammer, and it is calculated by inputting the value at the time of computational analysis and comprehensive test operation.

10. If the pressure in the air chamber is greater than the value of "10. Hydraulic pressure deviation" (refer to "9. Operating standard pressure + 10th water hammer pressure deviation") as a reference to "9. Operating pressure reference" (Compressor: OUT 01, 02, solenoid valve: OUT 05, 06) and "water shock" is stored in the memory as "water data" And "abnormal data" and generates alarms (OUT 13, 14, 16). At this time, the water pressure deviation value should be kept at least 1 second in order to cut off the abnormal signals such as noise.

The water hammer release delay time (20 minutes) of the water hammer establishing part 553 was normal due to water hammer and water level and pressure. All outputs are in the stop state (OUT 01, 02, 05, 06) during the "water deceleration delay time" and normal operation after this time has elapsed.

This is to prevent the malfunction of the equipment or the occurrence of a larger water hammer due to repeated operation of the delay circuit.

(1%, 0.1 K), the pressure and water level in the air chamber are continuously increasing and decreasing, and the time is gradually changed. The set value for solving the "water hammer control mode" is set to "17. If the water hammer control mode is canceled (ie, the water level changes by less than 1% per 10 seconds or the pressure changes within 0.1K per 10 seconds), if the water hammer change rate (per 10 seconds): 1% Compressor (OUT 01, 02) "or" air supply and exhaust solenoid valve (OUT 05, 06) "normally.

The valve setting unit 554 The value for setting the type of pressure sensor (PT, 4 ~ 20mA) is 20K for 100m or less, 30K for 100 ~ 200m and 50K for 200m or more. The value is input by the user.

(1) Adjustment of zero point of pressure sensor (+/- 0 K) is based on the pressure gauge when there is a difference between the value displayed on the pressure gauge and the value displayed on the controller screen, Add + or - to the displayed value of the pressure sensor and adjust the value displayed on the contoured roller screen to zero.

(2) Adjustment of the zero point of the level sensor (+/- 0 K) means that when there is no water in the air chamber at initial start-up and there is a difference between the value displayed on the liquid level meter and the value displayed on the controller screen, Adjust the value displayed on the controller screen to zero by adding + or - to the value of the water level of the sensor.

(3) The sensor error detection delay time (48 hours) occurs when the pressure sensor (PT, 4 to 20mA) or the level sensor (LT, 4 to 20mA) is abnormal (disconnection, abnormal signal, If there is a large fluctuation of more than 15mA per second, or if there is no change during the set time (48 hours), or if the minimum value (4mA) or the maximum value (20mA) "And" level sensor abnormality "abnormality content recording and alarm output (OUT 13, 14) is output. If" 21. Sensor abnormality detection delay time: 48 hours "is set to" 0 "

The compressor setting unit 555 If the input terminal "IN01" is closed (ON), this item does not send the output (OUT 01) to the compressor No.1 when the item is OFF. If the first compressor is turned OFF as the leading compressor, it is controlled by SKIP by the second compressor. If the first compressor is designated as the leading compressor and the input terminal IN 02 is closed (ON) (overcurrent is generated) .

On the other hand, the compressor No. 2 is an item for selecting whether the compressor operates or not. When the input terminal "IN02" is closed (ON), if this item is OFF, the compressor (OUT02) If the compressor is turned OFF as the leading compressor, it is controlled by SKIP by the second compressor. If the second terminal is designated as the leading compressor and turned ON, the input terminal IN 02 is closed (ON) .

On the other hand, in order to equalize the operation time of each compressor, the first and second compressor alternation periods (120 minutes) are set so that different compressors are operated after a certain time operation (using the integration time) Set the alternating operation time.

In addition, the primary compressor selection (Unit 1) selects the primary compressor. When the compressor designated as the primary compressor is the leading compressor and the compressor is in the operating condition, the compressor designated as the primary (leading) , And the leading compressor is: "28. Compressor alternation cycle" (accumulation time), the main compressor automatically shifts to the next compressor, and if the compressor to be designated as the leading compressor is set to "OFF" Can not be specified.

In addition, although the maximum operating time of the compressor (60 minutes) must be stopped within approximately one hour after the compressor starts operating, if the compressor is operated continuously for a long time due to any abnormality, the durability of the compressor is deteriorated due to high heat and abrasion. Set the time for operation with the compressor. (OUT 13, 14), the compressor is stopped and the next compressor is operated alternately when the compressor reaches the maximum operating time of compressor (accumulation time) The alternating compressor operation continues and the reason for generating the alarm is to allow the operator to confirm whether or not the compressor is abnormal.

The light setting unit 556 sets the light setting by the driving control logic 500, (OUT 13: buzzer, OUT 14: alarm), and when "31. Buzzer Time" elapses or the input terminal "IN 14: ON ", the output of the output terminal (OUT 13: buzzer) is stopped.

At this time, the output terminal (OUT 14) stops output only when the fault is cleared. If the "31. Buzzer Time" is set to "0", this function does not work, The output (OUT 13) continues to be generated

On the other hand, in the case of automatic return after power failure, when power supply is restored due to power failure during operation, it is automatically operated according to the current operating conditions. In the level priority operation, the pressure in the air chamber is indicated by reference. Level.

In addition, if the sensor (pressure, level) detection delay time (fixed value: 02 sec) is in the air chamber pressure or water level value, momentary noise or electric signal is inputted, The output is held for the delay time and the operation is performed according to the value after the delay time elapses.
