Multifunctional water pump control pneumatic valve in real life what applications

a pneumatic valve, multi-function water pump control profile
JDX series multifunctional water pump control pneumatic valve, whole process is a kind of automatic operation of the new hydraulic pneumatic valve, can achieve automatic centrifugal pump when the pump is open slow, stop the pump when the second phase of fast and slow closed shut, to prevent the reverse the medium inside the pipeline, the pneumatic valve can replace the water pump outlet pipe on the road at the same time operating pneumatic valve, pneumatic valve, double speed slow breath pneumatic valve check valve water hammer eliminator.
2, the design of a few big characteristics
. Main pneumatic valve plate and valve stem form sliding fit, pneumatic valve plate opening can change with size of the flow, thus can shut, when close to zero flow to achieve the most ideal state to eliminate water hammer.
. The diaphragm design control cavity, to avoid the piston cylinder type switch control cavity due to the resistance of the existence of failures. At the same time reduces the pressure, diaphragm material with the first reinforced nylon fibres reinforced neoprene, movement life ten thousand times.
. Than swing check pneumatic valve to reduce electricity %, design main pneumatic valve plate weight reduction, adopted streamlined spacious pneumatic seat design, drag coefficient. , much lower than drag coefficient. The pneumatic swing check valve.
. Convenient maintenance, based on the wide type pneumatic valve cover, without having to remove the connecting flange, to remove all pneumatic components in the valve.

3, operation data of pump model Sh A A motor KW rated speed r/min head m flow m/h test conditions:
. Automatic control of pneumatic valve open a second time, time will be automatically closed Seconds.
. Pneumatic valve in min after kai pump reaches the maximum opening. Four,

we use effect water than using the normal operation of the product months, accumulative total hours, without any faults, display the running state of the pneumatic valve is very stable.
. Meet the requirements of sluice gates were closed centrifugal pump start-up, to ensure the pump motor light load startup, no need for electric and oil pressure, can achieve directly to start-stop control of pump, not only solved the pipeline medium caused by sudden blackout for water hammer shock produced by pumping system, medium backflow, but also greatly reduces the labor intensity of workers.
. To eliminate water hammer effect is ideal, when the pump is going to close the pneumatic valve closed smoothly with no noise, vibration, pneumatic valve, due to this kind of control pneumatic valve depend entirely on the hydraulic automatic control, there is no need to personnel management.
