Connection base on submerged pump and oil cylinder assembly comprising same

Abstract

The invention discloses a connection base on a submerged pump and an oil cylinder assembly comprising the connection base. The oil cylinder assembly comprises a cylinder body and the connection base.The connection base comprises a base body, a water passing channel and a water passing port connected with the water passing channel are arranged in the base body, the upper end face of the base bodyis provided with a clamping block in clamped connection with a pump head assembly of the submerged pump, the oil cylinder assembly comprises the connection base and the cylinder body, the connection base and the cylinder body are both made from rigid plastic materials, the cylinder body is in clamped connection with the connection base, the side face of the cylinder body is provided with a cylinder body pin hole and a connection hole communicating with the cylinder body pin hole, the bottom of the base body is provided with a screw hole, the screw hole is connected with a pin shaft on the cylinder body pin hole through a screw, the cylinder body is provided with a cable outlet and an oil inlet correspondingly, a pressing plate and an oil feeding bolt on the cylinder body are in abutting connection fit with a pressing block and a pressing column of the base body correspondingly. The connection base has the advantages that the manufacturing process is simple, the cost is low, waterproofperformance is good, using firmness is good, and the service life of the submerged pump can be prolonged.

Description

Technical field [0001] The invention belongs to the technical field of components on submersible pumps, and in particular relates to a connecting seat on a submersible pump and an oil cylinder assembly formed by the connecting seat. Background technique [0002] At present, most of the connecting seats on submersible pumps are made of pig iron. Although the cylinder body made of this material has good hardness, its production process is more complicated, the production and transportation costs are high, and it needs to be combined with other parts in use. Connected and used, under normal circumstances, it is stacked up and down, which will be squeezed and offset during use, which will affect the stability and service life of the submersible pump (because it is made of metal, it is generally processed by lathe , It is more difficult to set the block structure); In addition, the existing oil cylinder assembly has poor sealing performance during use, and it is easy for external mois...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the connecting seats on submersible pumps are made of pig iron. Although the cylinder body made of this material has good hardness, its manufacturing process is relatively complicated, the production and transportation costs are high, and it needs to be integrated with other parts during use. When used in connection, in general, they are stacked up and down, which will be squeezed and shifted during use, which will affect the stability and service life of the submersible pump (because it is made of metal, it is generally processed by lathe) , it is more difficult to set up the block structure); in addition, the existing oil cylinder assembly has poor sealing performance during use, and it is easy for external moisture to enter the interior, thereby causing damage to the submersible pump; therefore, it is necessary to improve
