Abstract

The invention discloses an anti-misoperation device for a submersible pump cover pressure testing machine test bench, which is characterized in that it includes a ball valve, an operating handle, a pull wire, an upper horizontal plate, and an iron cover, and the operating handle is fixed on the On the ball valve, the lower end of the control handle is connected to the iron cover through the pull wire, and the iron cover is arranged on the outer side of the upper horizontal plate. The invention adopts the control handle to pull the pull wire to lift or lower the iron cover to close the water pressure system and the oil pressure system to prevent workers from misoperation, and has the advantages of simple structure, safety and reliability, and convenient use.

Description

technical field [0001] The invention relates to an anti-misoperation device for a test bench of a submersible pump cover press tester, which belongs to the technical field of measuring machinery. Background technique [0002] The operation sequence of the submersible pump cover test machine test bench is to put the submersible pump cover into the test bench for the test, first start the oil pressure system, use the hydraulic cylinder to tighten the submersible pump cover, and then conduct the water test; and When removing the submersible pump cover from the test bench, the hydraulic system should be turned off first, then the oil pressure system, and then the submersible pump cover should be removed. However, when workers are tired at work, or when they are not concentrating, they are easy to misuse, which may cause the pump cover of the submersible pump to fall from the test bench and injure the workers. Contents of the invention [0003] The purpose of the present inven...
