Centrifugal Water Pump for Water and Chemical Liquid

Product name: Centrifugal Pump for Water Treatmen, Daily Life, Agriculture, Industry Main uses: High-rise buildings, fire protection, refrigeration systems and industrial, agricultural, hotel, deep well Pumping water, fresh water and sea transport etc. Detailed use: 1, water supply: Water filtration and distribution, water supply main pipe water area, the first increase in pressure, Increased pressure of high-rise buildings. 2, industrial pressure: Industrial production water system, cleaning system, high pressure washing system, fire protection System. 3, industrial liquid conveying: Cooling and air-conditioning system, boiler feed water and condensate systems, machine Matching, acidic and alkaline medium transport. 4: Water treatment system, water treatment system, ultrafiltration system, reverse osmosis system distillation system, Separator and a swimming pool. 5, irrigation: Farmland irrigate, sprinkler irrigation, drip irrigation. The transmission medium: 1, Non flammable and explosive medium, thin, clean, containing no solid particles or fibers. 2, such as mineral water, softened water, pure water, thin sewage water, food oil and other light industry media. 3, pump the main material for stainless steel, can be used in pumping mildly corrosive media. The scope of performance parameter: Performance parameter scope the LDL series altogether has 7 varieties, 185 specification its performance parameter scope is: 1. Current capacity Q=4.9~324m3/h 2. Lifts H=18~310m 3. Rotational speed n=1480r/min 4. Power P=1.5~315kw 5. Induction port diameter Dna=40~200mm 6. Spout diameter DNm=40~150mm fault 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
