self priming centrifugal oil pump

CYZ-A series self-priming centrifugal oil pump is a new modified centrifugal pump which is developed on the basis of absorbing domestic and overseas advanced technology of the same product and combing many years design and manufacturing experience of our company.

It is widely used to transport gasoline,kerosene,diesel oil, oil for aviation in oil ware house, oil ≤station, oil tanker, dock, tank truck, airdrome etc. It can also be used in chemical industry, pharmaceutics, brew age, electroplate, printing and dyeing, papermaking, electric power, mine etc.

Medium temperature range:-20 Celsius degree to 80 Celsius degree, viscidity≤100centipoise, particles consistency can reach 30%. Working principle and structure indication The pump adopts pump case structure of axes direction back liquid.

The pump case consist of suction chamber, liquid deposit chamber, turbination chamber, back liquid bore, air and liquid separation chamber. After start the pump normally, impeller sucks liquid in suction chamber and air in suction pipeline and mixes them.

In centrifugal efficiency, liquid mixed air stream to outside of turbination chamber and turns into white spumy strap and liquid separation chamber by diffuse pipe.meanwhile because flow speed reduce suddenly, lighter air is separated from mixture and rises and put out of pump outlet from mixture.

Liquid from mixture is back to deposit chamber and enters into impeller by back liquid bore and mixes with air in suction pipeline once more, in efficiency of high rotary speed impeller, the liquid flow to edge of impeller\\\\ The process goes on continuously, air in suction pipeline reduces continuously and exhausts.

After finishing self-priming, pump is in normal work, because the pump has the particular output air performance, it can transport liquid with air in no need of bottom it has good function of cleaning cabin if it is used in tanker. Cool chamber is designed in some bearing bottom.

Cool liquid can be poured in to circulate and cool by any cool liquid pipe connecter in cool chamber when bearing temperature rises to 70 Celsius degree for heat. Seal unit is front seal ring in case of pump, and behind seal ring on bearing body, it can avoid leakage of liquid from high pressure area to low one.

The seal ring should be renewed when wear to rated condition for long operation to avoid effecting self-priming performance and efficiency of pump.

CHARACTERISTIC 1: it is self-priming centrifugal pump It stands out the advantage of simple structure, convenient operation and maintenance, stable working,high efficiency, long life, good self-priming performance etc.it need not bottom valve in the pipeline.

It just need to have amount of liquid in pump for self-priming before starting pump .it can be used as pump for cleaning off cabin in tanker and water supply of ship with high efficiency.2: it is made up o f material of high quality. Seal is hard alloy mechanical seal. So the pump has a long life.

It need not security valve in output pipeline and no bottom valve in suction pipeline ,so that it predigests pipeline system and improves working condition
