Problems solved by technology

After the large flow hydraulic diaphragm pump is installed, overhauled or stopped for a long time, it takes a long time for the traditional hydraulic system to replenish and drain the oil.
In addition, when the diaphragm in the prior art is in use, the position-limiting stability of the diaphragm is poor, and the sealing liquid is poor, so it is urgent to develop a dual-channel rapid oil replenishment structure to solve the problems in the prior art

Abstract

The invention relates to a double-channel rapid oil supplementing structure. The structure comprises a cylinder body, wherein a pump cavity is formed in the cylinder body, an oil pool is formed in the cylinder body, a plunger moving along the pump cavity is arranged in the pump cavity, a pump head is arranged on one side of the cylinder body, one-way valve sets are arranged at the upper end and the lower end of the pump head, a rapid emptying valve communicating with the oil pool is arranged at the upper end of the cylinder body, a sealing cavity is formed in the cylinder body, a first reversing valve is arranged between a rapid emptying valve and the pump cavity, a rapid oil supplementing valve communicating with the oil pool is arranged at the lower end of the cylinder body, a second reversing valve is arranged between the rapid oil supplementing valve and the pump cavity, a diaphragm is arranged in the sealing cavity, a limiting valve is arranged on the side, close to the diaphragm, of the pump cavity, and a pressure relief emptying group valve communicating with the pump cavity is arranged at the upper end of the cylinder body. The double-channel rapid oil supplementing structure is adopted, rapid oil supplementing and emptying can be achieved, oil supplementing and emptying by a pump can be completed within extremely short time, and the pump can rapidly enter a normal operation state.

Description

technical field [0001] The invention relates to the technical field of diaphragm pumps, in particular to a dual-channel rapid oil replenishment structure. Background technique [0002] The core technology of the hydraulic diaphragm pump is the pressure balance and stability of the hydraulic circulation system. The traditional hydraulic system is a single channel structure. After the large flow hydraulic diaphragm pump is installed, overhauled or stopped for a long time, it takes a long time for the traditional hydraulic system to replenish and drain the oil. In addition, when the diaphragm in the prior art is in use, the positioning stability of the diaphragm is poor, and the sealing fluid is poor. Therefore, it is urgent to develop a dual-channel rapid oil replenishment structure to solve the problems in the prior art. Contents of the invention [0003] The object of the present invention is to provide a dual-channel rapid oil replenishment structure to solve the proble...
