Horizontal Self-priming Centrifugal 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 combining many years design and manufacturing experience of our company.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 needs to have amount of liquid in pump for self-priming before starting pump.So it predigests pipeline system and improves working condition.
Horizontal Self-priming Centrifugal Pump is used in environment protection,construction,fire protection,chemical industry,pharmacy,printing and dyestuff,brewage,electric power,electroplate,papermaking,washing for industry and mine,cool for device.
It can spray by turning water into little drop for farm,garden etc.
It is suitable for clear water,sea water and chemical medium with acid and alkali and mushy slurry (viscosity<=100 centipois, consistency for solid can not exceed 30%of total medium.
It can be used to transport slurry to compressor and filter with compressor and filter.
Horizontal Self-priming Centrifugal Pump adopts the structure of axial flow liquid. Pump case consists 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 ring with high rotary speed in out edge of impeller. Mixture with air and liquid enter into air and liquid separation chamber by diffuse pipe. Meanwhile because flow speed reduces suddenly,lighter air is separated from mixture and rises and put our 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 flows 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 horizontal self-priming centrifugal pump has the particular output air performance,it can transport liquid with air in no need of bottom. It has the good function of cleaning cabin if it is used in tanker. Cool chamber is designed in the bearing bottom of some pumps. 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℃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 wearing to rated condition for long operation to avoid effecting self-priming performance and efficiency of pump.
