Abstract

A reversing mechanism acting on a reciprocating pump, belonging to the technical field of hydraulic control, comprising a left working cylinder end cover and a right working cylinder end cover, a left push slide rod, a right push slide rod, two push slide rod sliding sleeves, Composed of induction push rod, left sliding sleeve, right sliding sleeve and elastic elements; the working principle is clear, and the structure combines the induction sliding rod and the pushing sliding rod. The pushing sliding rod is acted by the spring and has a certain axial bearing capacity. It can prevent the water pressure of the sewage chamber from pushing the reversing rod, which solves the problems of the reversing mechanism such as early movement and reciprocating disorder, increases the stability of the reversing mechanism, prolongs the service life of the reversing mechanism, and further improves the working efficiency of the equipment. improvement.

Description

technical field [0001] The invention belongs to the technical field of hydraulic control, and relates to a reversing mechanism, in particular to a reversing mechanism acting on a reciprocating pump. Background technique [0002] With the increasingly severe environmental situation, the control and treatment of pollutants has become urgent, and the role of equipment in the water treatment industry is becoming more and more important. The application of reciprocating pumps in water treatment is also becoming more and more prominent. The reciprocating pump is recognized as the technological leader of the "reciprocating pumping system" in the world. It can pump sewage filtration residues with a solid content of 56%, and even other slurry and sludge with a solid content of 80%. Reciprocating pumps Hydraulic pressure is used as the drive, and there is a double-circuit hydraulic system in the equipment, so that the lift valves and differential cylinders of the two working cylinders...
