Product Description

Products Name:Horizontal multistage centrifugal pump

Specifications
1. high efficiency& save energy
2. long lasting
 
Application
LQDWF type pump are mainly used in industrial field:
Air-conditioning system
Cooling system
Industrial cleaning
Water treatment(Water purification)
Aquiculture
Fertilizing / metering system
Environmental application
Other special applications
Applicable medium
Thin and clean non-flammable and non-explosive liquid without solid granules and fibers.
Mineral water, soft water, pure water, edible vegetable oil and other light chemical mediums.
When the density or viscosity of to-be-conveyed liquid is larger than that of water, it is necessary to select a driving motor of high-power.
Whether a specific liquid is suitable for the pump depends on many factors, among which the most important ones are chlorine content, PH value,temperature, solvent and oil content.
Operation condition
Liquid temperature:
Normal temperature type: -15 celsius~+70 celsius
Hot water type: +70celsius~+110celsius
Highest ambient temperature: +40celsius
Max.operation pressure :10 bar
Max.inlet pressure is limited by max.operation pressure
Pump
Horizontal multistage non-self-priming centifugal pump, attached with long shaft electric motor.
Compact structure renders small size of pump;axial inlet and radial outle

fault phenomenon	failure cause	elimination methods
	1.No power supply or one or two phase power supply is needed	Check all phases of power supply and restore power supply
	2.Poor contact of ac contactor and burning of coil	Repair or replace contactors
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
	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 low	Put water in the sink
	The motor burned	Repair or replace the motor
	1.Line is loose	Check wiring and tighten connectors
	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
	5The pressure transmitter is damaged	Repair or replace
	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	Too much flow, impeller wear	Check whether the pump shaft is bent, replace the impeller, close the outlet valve to reduce the flow
