Product Overview: CYZ-A self-priming centrifugal oil pump is the latest pump product developed according to the domestic and foreign technical data after digestion, absorption and improvement. The pump is ideal for the oil industry, land oil depots, and tank trucks. Products, and suitable for marine cargo pumps, bilge pumps, fire pumps and ballast pumps and machine cooling water circulation, respectively, to deliver gasoline, kerosene, diesel, aviation coal and other petroleum products and seawater, water, medium temperature -20 °C - 80 °C, such as the transport of chemical liquids can be replaced with corrosion-resistant mechanical seals.
Features
The pump is a self-priming centrifugal pump, which has the advantages of simple structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming ability. The bottom valve is not required in the pipeline, and only the quantitative oil in the pump body can be stored before the work. When used on oil tankers or water tankers, it can double as a stripping pump and has good stripping effect. It is made of high-quality materials, sealed with a hard alloy mechanical seal, durable, no need to install a safety valve for the discharge pipe, and no bottom valve is required for the suction pipe, thus simplifying the piping system and improving the working conditions.
Product Usage
Suitable for marine cargo pumps, bilge pumps, fire pumps and ballast pumps, and machine cooling water circulation, etc., respectively, transporting petroleum products such as gasoline, kerosene, diesel, aviation coal and sea water, fresh water, medium temperature -20 °C ~ 80 °C, such as Chemical liquid transport can be replaced with a corrosion-resistant mechanical seal.

Troubleshooting
|
malfunction
|
cause
|
Method of exclusion
|
|
Oil pump does not come out of oil
|
1. There is not enough fluid or fluid in the pump casing
2. Inhalation line leak
3, wrong speed
4, suction process is too high or suction line is too long
5, mechanical seal leakage is too large
6, the suction pipe gas can not be discharged from the outlet
|
1, add enough liquid
2. Check and eliminate leakage
3, adjust the direction
4, reduce suction or shorten the suction line
5, repair or replace
6, open the outlet valve
|
|
Large noise and vibration
|
1, unstable foot
2, the pump shaft bending
3, cavitation
4, bearing wear serious
5, there are impurities in the import pipeline
6. Concentricity between spindle and pump
|
1, reinforcement
2, replace or correct
3, adjust the working conditions
4, replace
5, remove debris
6, adjust the concentricity
|
|
Insufficient oil
|
1, debris into the suction pipe or impeller flow is blocked
2, the speed is too low
|
1, remove the blockage
2, adjust to the rated speed
|
|
Shaft power consumption is too large
|
1, excessive traffic
2, the speed is too high
3, pump shaft bending or impeller stuck
4, the pump flow channel blocked or stuck
|
1, increase the export pressure
2, appropriately reduced
3, replacement or correction
4, remove the blockage
|
