Manufacture Electric Water Vertical Multistage Centrifugal Pump

 

Manufacture Electric Water Vertical Multistage Centrifugal Pump1, CDLF series light stainless steel vertical multistage pump

 
CDLF series light stainless steel vertical multi-stage centrifugal pump (hereinafter referred to as multi-stage pump) is a non self-priming vertical multi-stage centrifugal pump designed and manufactured by absorbing domestic and foreign technology. It adopts standard vertical motor and quick installation mechanical seal, which is easy to replace.
The overflow part of the pump is made of stainless steel (304-316), which is suitable for mild corrosive medium. This product can replace similar products such as Cr and CrN abroad. After the product is put into the market, it is deeply loved
by the majority of users for its high efficiency, energy saving, good quality and wide range of use.
 
2, CDLF series light stainless steel vertical multi-stage pump features:
 
1. The use of excellent model and hydraulic technology greatly improves the service life of the pump. 2. As the shaft seal is made of cemented carbide and fluororubber, the temperature of pump running and conveying medium can be increased. 3. The overflow part of the pump is made of stainless steel plate stamping and welding, which makes the pump suitable for mild corrosive medium. 4. It has compact structure, small volume, light weight, low noise, remarkable energy saving effect and convenient maintenance. 5. The water inlet and outlet of the multi-stage pump are located on the same horizontal line of the pump seat, which can be directly used in the pipeline. 6. Using standard motor, users can easily equip motor according to their needs. 7. According to the needs of users, intelligent protector can be equipped to effectively protect the pump from dry running, phase loss and overload. 3, CDLF series light stainless steel vertical multistage pump conveying medium: 1. Thin, clean, non flammable and explosive media without solid particles or fibers. 2. Such as mineral water, softened water, pure water, clean oil and other light chemical media. 3. The main material of the pump is stainless steel, which can be used to transport mild corrosive medium.

Fault phenomenon
                        Possible causes
                     Exclusion method
 
 
 
 
 
 
1.The water pump doesn't come out
 
 
 
A.The inlet and outlet valves are not      opened, the inlet and outlet pipelines are blocked, and the runner impeller is blocked
B.The running direction of the motor is wrong, and the speed of the motor is slow due to the lack of items
C.Air leakage of suction pipe
D.The pump is not filled with liquid and there is air in the pump chamber
E:The inlet water supply is insufficient, the suction head is too high, and the bottom valve leaks
F:The pipeline resistance is too large and the pump selection is improper
A:Check and remove obstruction
B:Adjust the motor direction and tighten the motor wire
C:Tighten all sealing surfaces to remove air
D:Open the pump cover or open the exhaust valve to exhaust air
E:Shut down for inspection and adjustment (this phenomenon is easy to occur when the grid connected water pipe is used with suction
head)
F:Reduce the pipeline bend, re select the pump
 
 
2. The flow of water pump is insufficient
A:Press 1 to check the cause
B:The pipeline and the impeller of pump passage are partially blocked, and the valve opening is insufficient due to scale deposition
C:The voltage is low
D:Impeller wear
 
A:Press 1 to exclude
B:Remove the blockage and readjust the valve opening
C:Voltage stabilization
D:Impeller replacement
 
 
3.Excessive power
A:Use in excess of rated flow
B:Suction head too high
C:Pump bearing wear
 
A:Adjust the flow and close the outlet valve
B:reduce
C:Replace the bearing
 
 
 
4.Noise and vibration
A:Unstable pipeline support
B:Liquid mixed with gas
C:Cavitation is produced
D:Bearing damage
E:Motor overload operation
A:Secure the piping
B:Increase suction pressure, exhaust
C:Reduce the vacuum
D:Replace the bearing
E:Adjust by pressing 5
 
 
5.Motor heating
A:Excessive flow, overload operation
B:local friction
C:Motor bearing damage
D:Insufficient voltage
A:Turn down the outlet valve
B:Check and eliminate
C:Replace the bearing
D:Voltage stabilization
 
 
6.Water pump leaking
A:Wear of mechanical seal
B:There are sand holes or cracks in the pump body
C:Uneven sealing surface
D:Loose bolt installation
A:replace
B:Welding repair or replacement
C:Trimming
D:Tight confinement
