Abstract
The utility model discloses a centrifugal mud pump, comprising a vortex shell, a pedestal, a shaft and a belt sheave, wherein the belt sheave ,the pedestal ,the cooling lubrication tank and the impeller are consecutively connected to the shaft, with the cooling lubrication tank fixedly connected with the belt sheave, the vortex shell sheathed outside the pedestal, the rear end of the vortex shell connected with the cooling lubrication tank, the sealing element positioned between the tank and the shaft, the front end of vortex shell connected with an anti-attrition shell, thereby preventing the attrition of the vortex shell, uneasy to be blocked or broken and leak-proof, with a good effect of cooling lubrication, The utility model has the advantages of low cost and low power consumption, high efficiency and long service life, applicable to capture mud in water.
Description
Technical field
The utility model relates to a kind of shell pump that is used to draw silt.
Background technique
Known shell pump mainly is made of volute, impeller, axle, sealing etc.The impeller of this shell pump is the rotary flow type impeller, and when drawing silt, power consumption is big, and easily stops up.Volute, damage in impeller are fast, can't change, and working life is short.Sealing damages easily, gas leakage, user cost height.
Summary of the invention
The purpose of this utility model is that a kind of centrifugal shell pump will be provided, and this pump is low in energy consumption, and the life-span is long, and user cost is low.
The purpose of this utility model is achieved in that this shell pump comprises volute, pedestal, axle and belt pulley, belt pulley, pedestal, cooling and lubricating water tank, impeller are connected in turn on the axle, the cooling and lubricating water tank is fixedlyed connected with pedestal, volute is enclosed within the impeller outside, the volute rear end links to each other with the cooling and lubricating water tank, Sealing is between cooling and lubricating water tank and axle, and the volute front end is connected with the anti-attrition cover.
Described impeller is centrifugal, and the front of impeller is a curved cover plate, and the blade of impeller is distortion gradually from import to outlet.
Volute front end of the present utility model is connected with the anti-attrition cover, has avoided the wearing and tearing of volute.Impeller is centrifugal, and the front of impeller is a curved cover plate, thereby is difficult for stopping up.Sealing is between cooling and lubricating water tank and axle, and cooling and lubricating is effective, seals not fragile.User cost is low, and is low in energy consumption, the efficient height, and the life-span is long, can be used for drawing the silt in the water.
