The installation of the pump cover and the pump shell of the explosion-proof wine pump (self - sucking pump) is divided into the following steps:

The first step is to install the pump case on the machine seat. The second step is to assemble the components of the explosion-proof pump, the pump cover and the pump body into the pump casing, and then install the whole machine on the machine seat. The key to assembly is to ensure that the impeller is in a normal working position. Depending on the mating surface of the pump cover and the pump body, the coaxality of the sealing ring of the impeller population and the pump body is ensured. The gasket between the pump body and the pump cover has double functions of sealing and adjusting the axial position of the impeller.

When installing, the gasket shall be mounted first, then the impeller and the pump cover shall be pushed into the human pump body along the axial direction, the pump cover bolts should be tightened, and the pump shaft should be screwed at the side to move the pump shaft. If there is any friction between the impeller and the sealing ring, it should be adjusted in time. The sealing pad can be made with rubber plate or rubber asbestos board and other materials. After the adjustment of the gap between the various parts, the use of bolts to fasten the pump cover and the pump shell together.
