High Pressure High Flow Irrigation Water Pump

1. pplication Conditions: LQDL (F) is aplicable for conveying the cold and hot cleaning water with the temperatures between -30C and +150C or the liquid which is not flammable or explosive, or they are free of solid particles or fibers. The maximum environment temperature is +40C.  2. Performance Parameters: Flow Q= 1.0~180 3/hHead H= 7~268 mRev n=2950 r/minPower P=0.37~75 kwInlet diameter Dna=25~125mmAllowable working pressure ≤25~40 barRated frequency: 50 Hz or 60 Hz  3. Advantages: Those with "F" means corrosion resistibleSmall sizeEffective Less vibrationEasy maintaing  4. Applications: Circulative pressure increasing Water filtering in waterworksLiving water supplyFire fighting systemAir conditionerfault phenomenonfailure causeelimination methods 1.No power supply or one or two phase power supply is neededCheck all phases of power supply and restore power supply  2.Poor contact of ac contactor and burning of coilRepair or replace contactors can not start3.The power switch is not closed, malfunction or damaged Close the switch and replace it if the power indicator does not turn on 4.Thermal relay trip or damage Check whether the motor is blocked, find out the reason and eliminate it.Manual reset is replaced if it cannot be started Water level is too lowPut water in the sink  The motor burnedRepair or replace the motor  1.Line is looseCheck wiring and tighten connectors  2.Frequency converter malfunctionCheck the fault content, check the cause according to the frequency converter manual, and restart after reset.Or disconnect the inverter power supply for a few seconds, the inverter fault reset before starting.The manual is normal3The frequency converter is damagedRepair or replaceAutomatic transmission failure4.Pressure switch damageRepair or replace 5The pressure transmitter is damagedRepair or replace 6.Switch failureRepair or replacePump non - suction pressure gauge pointer to beat violentlyInsufficient water supply for perfusion, air leakage at the connection between pipeline and instrumentCheck pipeline and bottom valve, refill water diversion. Tighten air leakageThe pump consumes too much power Too much flow, impeller wear Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
