Pump

Abstract

The invention discloses a pump which comprises a pump body, a base and an end cover, wherein the pump body is connected with a joint above the pump body; the end cover is installed above the joint; a cavity is arranged inside the joint; a baffle plate is installed in the cavity of the joint; the baffle plate moves along the cavity; the lower end of the baffle plate contacts a rotor; the rotor is arranged in the pump body; a hole is formed on one side in the middle of the upper end of the pump body; the hole is isolated into a liquid inlet through the baffle plate; and a liquid outlet and an alternative liquid outlet are formed in symmetry on two sides of the lower end of the pump body. Compared with an ordinary pump, the pump has the advantages that the rotor of the pump can be tangent to the inner chamber of the pump body and is in tight contact with the lower end of the baffle plate, the pump can do work at a speed larger than zero, and the pump is larger in dust flying, smaller in pulse and smaller in part abrasion than the ordinary pump.

Description

technical field [0001] The invention relates to a conveying device for increasing fluid pressure, in particular to a pump. Background technique [0002] At present, the pumps on the market are divided into water pumps, oil pumps and air pumps. The flow rate of the water pump is large, but the outlet pressure is small, the dust of the single machine is small, and the cavitation allowance is large. In order to obtain the work of high dust and large flow, people have to adopt multi-pole The result is that the overall efficiency of the pump unit will be reduced and the cost of use will be increased; while the oil pump has the disadvantages of high pressure, small flow, and short service life due to pulsation. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a pump with less pulsation and less wear on parts. [0004] The technical scheme adopted in t...
