Description
Technical field
The utility model relates to a kind of water pump and water pump water outlet valve, relates in particular to the linkage of a kind of water pump and water pump water outlet valve.
Background technique
The valve basic control principle is to utilize the working principle of reversible magnetic starter to realize the clockwise and anticlockwise control to valve, and the button of often opening that utilizes valve to reach on the spot on the operation screen simultaneously parallelly connected with the normally opened contact of corresponding contact device in the magnetic starter is realized valve on the spot with concentrated open and close, stopped operating.As shown in Figure 1, after water pump was opened, operator judged that rule of thumb water pump pressed Open valve button SB2 or concentrated Open valve button SB5 on the spot during proper functioning; Open the charged work of valve contactor KM1 coil; Its normally opened contact adhesive forms self-locking in control loop, simultaneously to the valve driving machine main circuit power supply; The charged work of valve driving machine, valve begins to open.This working method mainly relies on operator's experience to realize the control to valve, is easy to cause the long-time zero delivery operation of water pump, brings unnecessary electric energy loss.After water pump is stopped transport; Operator rule of thumb judge and press throttle down button SB3 or concentrated throttle down button SB6 on the spot when water pump has quit work, close the charged work of valve contactor KM2 coil, its normally opened contact adhesive; In control loop, form self-locking; Simultaneously to the valve driving machine main circuit power supply, the charged work of valve driving machine, valve begins to close.This working method relies on operator's experience to realize the control to valve equally, is easy to cause water hammer, shortens the working life of water pump.In addition, after the water pump fault is jumped car,,, can produce water hammer to water pump equally so valve can not closed automatically because valve does not have self-closing device.
Overcome above problem, must realize the interlock of water pump and valve.Water pump and valve linkage manner commonly used at present have: utilize software realization in the microcomputer protecting device, this mode is behind the pump motor divide-shut brake, to realize the switch of valve for switching signal of valve through certain time-delay (by software set); Another kind of mode is to utilize the auxiliary contact of pump motor circuit breaker to realize; When the pump motor circuit breaker divide fashionable; Synchronous deciliter of auxiliary contact utilizes auxiliary contact and auxiliary reclay, time delay relay to realize the switch of valve after certain time-delay, for switching signal of valve.Can prevent the appearance of operation of water pump zero delivery and water hammer generally speaking with upper type; But the time that prolongs is set through calculating or experience by the people, and along with the variation of water pump operate outside environment such as absorbing well, absorption well water level, the time of prolongation often not exclusively conforms to field condition; In addition; Need purchase software or the relay delay circuit is installed, need by high-tension switch cabinet to valve control loop cabling, so investment is big, the fault point is many.
