Product Description

Centrifugal submersible pump with stainless steelvertical multistage

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.
Product overview

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
