Abstract
The utility model relates to a self-suction dirty discharging pump which comprises a pump body and an impeller, wherein a pump isolation tongue is arranged between an air-water separation chamber at the lower part of a liquid outlet of the pump body and the impeller, the air-water separation chamber is communicated with a refluxing chamber, and the refluxing chamber is communicated with a pump chamber by refluxing holes. The utility model is characterized in that the pump isolation tongue recesses in the air-water separation chamber and forms a certain spacing with the impeller. The utility model overcomes the defects of complex production process, lower reliability, high failure rate of a general self-suction dirty discharging pump. The utility model has the advantages of simple structure, wide application ranges and high reliability. The utility model is water discharging equipment with good quality for environmental protection, urban construction, etc.
Description
The utility model relates to a kind of self-priming pollution discharge pump.
Existing various self-priming pollution discharge pump, its pump cut water all is arranged on the bottom of air-water separation chamber, and the distance between the impeller is quite near, filth-discharging effect is relatively poor, in order to address this problem, people adopt the method that reduces length of blade in the impeller usually, but the production technology that the self-priming blowdown of this structure is shown is comparatively complicated, reliability is low, and rate of fault in actual applications is higher.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby a kind of self-priming pollution discharge pump of simple in structure, applied widely, good reliability is provided.
The utility model comprises the pump housing and impeller, be provided with the pump cut water between the air-water separation chamber of pump housing liquid outlet below and the impeller, air-water separation chamber and refluxing chamber are communicated with, and refluxing chamber is communicated with pump chamber by return port, the recessed air-water separation of pump cut water is indoor, and and impeller between form certain spacing.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises the pump housing 1 and impeller 2, one side of the pump housing 1 is provided with liquid entering hole 9, be provided with pump cut water 4 between the air-water separation chamber 3 of liquid outlet 10 belows and the impeller 2, air-water separation chamber 3 and refluxing chamber 5 are communicated with, refluxing chamber 5 is communicated with by return port 6 and pump chamber 7, in the recessed air-water separation chamber 3 of pump cut water, and and impeller 2 between form certain spacing 8.Under user mode, be subjected to the drive of prime mover, the impeller 2 of high speed rotating together throws away water storage in the pump and air, and in air-water separation chamber, air water separates rapidly, air is discharged from liquid outlet 10, water enters pump chamber 7 through refluxing chamber 5 by return port 6, and is sucked by impeller 2 again, so repeatedly circulation, until the suction of the air in the inlet tube 11 is clean, pump begins proper functioning.
The utility model is by above-mentioned concrete setting, have simple in structure, applied widely, reliability is strong Deng outstanding advantages, be a kind of high-quality drainage equipment that is applicable to the industries such as environmental protection, urban construction.
