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/h Head H= 7~268 m Rev n=2950 r/min Power P=0.37~75 kw Inlet diameter Dna=25~125mm Allowable working pressure ≤25~40 bar Rated frequency: 50 Hz or 60 Hz   3. Advantages:  Those with "F" means corrosion resistible Small size Effective Less vibration Easy maintaing   4. Applications:  Circulative pressure increasing Water filtering in waterworks Living water supply Fire fighting system Air conditioner 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.

fault phenomenon
failure cause
elimination methods
Â
1.No power supply or one or two phase power supply is needed
Check all phases of power supply and restore power supply
Â
Â
2.Poor contact of ac contactor and burning of coil
Repair or replace contactors
Â
can not start
3.
The power switch is not closed, malfunction or damaged
 Close the switch and replace it if the power indicator does not turn on
Â
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
Â
Water level is too low
Put water in the sink
Â
Â
The motor burned
Repair or replace the motor
Â
Â
1.Line is loose
Check wiring and tighten connectors
Â
Â
2.Frequency converter malfunction
Check 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 normal
3The frequency converter is damaged
Repair or replace
Automatic transmission failure
4.Pressure switch damage
Repair or replace
Â
5The pressure transmitter is damaged
Repair or replace
Â
6.Switch failure
Repair or replace
Pump non - suction pressure gauge pointer to beat violently
Insufficient water supply for perfusion, air leakage at the connection between pipeline and instrument
Check pipeline and bottom valve, refill water diversion. Tighten air leakage
The pump consumes too much power
Â
Too much flow, impeller wear
 Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow
