Plastic pump shaft assembling machine

Abstract

The invention provides a plastic pump shaft assembling machine, and belongs to the technical field of machinery. The plastic pump shaft assembling machine comprises a rack and is characterized in thatthe rack is provided with an annular sliding groove, and a plurality of sliding blocks are slidably arranged in the sliding groove and can circularly move in the sliding groove; each sliding block isprovided with a clamping mechanism used for fixing a main shaft; the rack is further fixedly provided with a first air cylinder used for pushing the sliding blocks to move leftwards, a second air cylinder used for pushing the sliding blocks to move rightwards and a third air cylinder used for pushing the sliding blocks to move upwards; the first air cylinder is located over the rack, the second air cylinder is located under the rack, and the third air cylinder is located on the side, far away from the second air cylinder, of the rack; and a first containing bracket is fixedly arranged on therack, and the two ends of the first containing bracket are each provided with a first conveying mechanism used for conveying a left protecting shell or a right protecting shell. The plastic pump shaftassembling machine has the characteristic of being high in assembling efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, in particular to a pump shaft assembly machine for plastic pumps. Background technique [0002] Problems caused by pump cavitation: The main reasons for pump cavitation are large pump inlet pipe resistance, more gas phase of the conveying medium, insufficient filling of the pump, and insufficient energy head at the pump inlet. Cavitation is the most harmful to the pump. When cavitation occurs, the pump vibrates violently and the balance is seriously damaged, which will cause damage to the plastic pump bearing and pump shaft. [0003] The current plastic pump shaft material is made of silicon carbide or ceramics. These two materials are easy to break under improper operation or when the pump shaft is locked, the pump shaft and the motor are not concentric, idling, dry hitting, etc. [0004] Now a new type of pump shaft is used, which requires multiple parts to be assembled, which will lead to i...

Problems solved by technology

[0002] Problems caused by pump cavitation: The main reasons for pump cavitation are large pump inlet pipe resistance, more gas phase of the conveying medium, insufficient filling of the pump, and insufficient energy head at the pump inlet, etc.

Cavitation is the most harmful to the pump. When cavitation occurs, the pump vibrates violently and the balance is seriously damaged, which will cause damage to the plastic pump bearing and pump shaft.

[0003] The current plastic pump shaft material is made of silicon carbide or ceramics. These two materials are easy to break under improper operation or when the pump shaft is locked, the pump shaft and the motor are not concentric, idling, dry hitting, etc.

[0004] The new type of pump shaft is now used, which requires multiple parts to be assembled, which will lead to inefficiency if assembled manually
