Sliding rotating conveniently-maintained horizontal single-stage pump

Abstract

The invention discloses a sliding rotating conveniently-maintained horizontal single-stage pump. The sliding rotating conveniently-maintained horizontal single-stage pump comprises a pump body, an electric motor combined component, a sliding rotating device, a positioning locking device and a base; the pump body is fixedly arranged on the base, the pump body and the electric motor combined component can be detachably connected, a guide rail is arranged on the base, the sliding rotating device is arranged on the guide rail, the electric motor combined component is arranged on the sliding rotating device, and the positioning locking device is used for fixing the sliding rotating device to the base. During maintaining or repairing, the electric motor combined component and the pump body only need to be detached, the electric motor combined component slides out along the guide rail and then is rotated, an impeller, a mechanical seal and a seal ring in the pump and a pump cover, a water stop ring and an electric motor outside the pump are maintained or replaced, the positioning locking device enables the pump body and the electric motor combined component to be precisely positioned, and normal work of the sliding rotating conveniently-maintained horizontal single-stage pump can be ensured.

Description

technical field [0001] The invention relates to the technical field of fluid general machinery, in particular to a sliding-swing, easy-to-maintain horizontal single-stage pump. Background technique [0002] Existing horizontal single-stage pumps are usually composed of pump body, impeller, pump cover, mechanical seal, sealing ring, water retaining ring and motor, which are assembled and then installed on the base; in actual use, maintenance is difficult and operation Inconvenient troubles, because when this kind of pump needs maintenance, although the pump body can be kept on the base, it is necessary to remove the connecting bolts between the motor and the base, and then remove the connecting bolts at the joint between the pump cover and the pump body. Then it is necessary to use lifting equipment to remove the heavy motor, pump cover, impeller, mechanical seal and other components, so that the impeller, mechanical seal, sealing ring in the pump and the external pump cover,...

Problems solved by technology

[0002] Existing horizontal single-stage pumps are usually composed of pump body, impeller, pump cover, mechanical seal, sealing ring, water retaining ring and motor, which are assembled and then installed on the base; in actual use, maintenance is difficult and operation Inconvenient troubles, because when this kind of pump needs maintenance, although the pump body can be kept on the base, it is necessary to remove the connecting bolts between the motor and the base, and then remove the connecting bolts at the joint between the pump cover and the pump body. Then it is necessary to use lifting equipment to remove the heavy motor, pump cover, impeller, mechanical seal and other components, so that the impeller, mechanical seal, sealing ring in the pump and the external pump cover, water retaining ring and motor can be maintained or repaired. It is necessary to restore the assembly after the maintenance is completed; it can be seen that the maintenance operation is not only time-consuming and labor-intensive, but also the labor intensity of the operator is also high.
