Description
Technical field
The utility model relates to a kind of industrial pump, relates in particular to a kind of chemical industry Under Water Pumps.
Background technique
The underwater pump that Vehicles Collected from Market occurs, be made up of the pump housing, pump head, connecting pipeline and control gear, the pump housing comprises shield electric machine and centrifugal pump, and motor and centrifugal pump coaxially connect, and outside forms inseparable entirety according to fluid aspirator; Its major advantage is: the bearing of pump only has hundreds of millimeter, does not have major axis, there will not be vibration problems, operate steadily, and sound is very little, does not does not almost wear and tear, and is applicable to carry the multiple Lightness media such as inflammable and explosive.But it is not suitable for carrying with particle, having extremely strong corrosive high viscosity medium.
Summary of the invention
The purpose of this utility model be to provide a kind of wear-resistant, No leakage, occupation of land less, chemical industry Under Water Pumps easy for installation.
The utility model realizes like this, a kind of chemical industry Under Water Pumps, comprise the pump housing, pump shaft, drain pipe, base, motor cabinet, described pump shaft upper end connects with shaft coupling, pump shaft lower end to be connected and fixed impeller by impeller nut, described pump shaft lower end and pump cover connection place are provided with Lower shaft sleeve, lower axle bush from inside to outside, described pump shaft and packing seal connection place are provided with Upper shaft sleeve, described pump shaft and bearing box connection place are provided with bearing housing, the bearing housing in described bearing box be respectively arranged with deep groove ball bearing and thrust ball bearing up and down.
Further, the outlet end of described drain pipe is provided with two halves flange.
The beneficial effects of the utility model:
1, the utility model pump shaft and pump cover, packing seal and bearing box place are provided with axle sleeve, decrease the wearing and tearing of pump shaft, substantially prolongs its working life.
2, the utility model adopt deep groove ball bearing and thrust ball bearing with the use of, while bearing radial load, also can bear certain thrust load, thus solve the beating of pump shaft, wear problem.
3, the utility model entirety is directly installed on the storage of transported medium by base plate, without additional floor space, thus reduces capital construction input.
4, eliminate mechanical seal, solve other
under Water Pumpsthe worry must often keeped in repair because mechanical seal is is easily worn and torn, has saved the operating cost of pump, has improve working efficiency.
