Problems solved by technology

[0003] 1) Since there are many parts in the built-in and external oil replenishment structures, the structure is relatively complicated, and the range of motion between the matching parts is more than 5 mm, which is prone to wear and tear, and the failure rate increases accordingly;
[0004] 2) Most of the components of the built-in and external oil replenishment structures are located inside the hydraulic end, and the pump head, inlet and outlet pipes, and inlet and outlet valve groups must be removed during maintenance, which requires a relatively large workload and complicated processes

Abstract

The invention aims at providing a hydraulic diaphragm pump with an oblique-pulling controllable oil filling structure, and relates to the field of the hydraulic diaphragm pumps. The hydraulic diaphragm pump with the oblique-pulling controllable oil filling structure comprises a pump head, a cylinder body, a hydraulic cavity limitation plate, a diaphragm sheet, a diaphragm protective plate turnover cover, a diaphragm protective plate seat and the oil filling structure, wherein the oil filling structure is mounted on the cylinder body, and comprises a turning handle, an oblique-pulling rod, an oil filling tube seat, a valve seat, a valve core, a spring, a spring seat and an ejection rod. The hydraulic diaphragm pump with the oblique-pulling controllable oil filling structure is simple in structure; the number of parts is few; a failure rate is low; the mounting and dismounting of the oil filling structure can be completed by an oil filling structure mounting hole positioned in the cylinder body, without dismounting the pump head; the operation is easy and simple; and a workload is light.

Description

technical field [0001] The invention relates to the field of hydraulic diaphragm pumps, in particular to a hydraulic diaphragm pump with a cable-stayed controllable oil supply structure. Background technique [0002] The oil charge system is an important part of the hydraulic diaphragm reciprocating pump. Its function is that when the hydraulic oil in the hydraulic chamber of the hydraulic diaphragm reciprocating pump decreases due to leakage, the hydraulic oil can be replenished to an appropriate amount in time through the controllable oil replenishment structure, so that the diaphragm is not easily damaged, so as to maintain the pump. for normal operation purposes. The existing technology adopts the built-in oil replenishment structure and the external structure, and respectively applies the principle of leverage and the principle of inclined plane, which has the following disadvantages: [0003] 1) Since there are many parts in the built-in and external oil replenishmen...
