Plunger pump with grease stored inside

Abstract

The invention relates to the technical field of plunger pumps, in particular to a plunger pump with grease stored inside. According to an existing general grease adding method, generally, after the plunger pump works for schedule time, a grease adding tool is directly used for adding grease, or a grease cup is directly installed on the plunger pump, the grease is added in the grease cup, once the grease is added, a machine needs to be shut down, the job schedule is influenced, or the structure of the plunger pump is complicated, and the manufacturing cost of the plunger pump is further increased. The plunger pump with grease stored inside comprises a cylinder body and a plunger arranged in the cylinder body. A grease storing and sealing mechanism is installed on the plunger and is in sealing fitting with the plunger and the cylinder body. The plunger pump with grease stored inside utilizes an oil sealing ring and a gasket to store the grease in the plunger pump to achieve the purpose of avoiding follow-up grease addition and lubricating the plunger, the plunger pump can work continuously, and the situation that due to lubricating failure, the sealing part installed on the plunger is damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of plunger pumps, in particular to a plunger pump for internal storage of butter. Background technique [0002] The plunger pump is an important device in the hydraulic system. It relies on the plunger to reciprocate in the cylinder to change the volume of the sealed working cavity to realize oil absorption, oil pressure or water absorption and water pressure. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, and is widely used in high pressure, large flow and flow adjustment occasions, such as hydraulic presses, agricultural irrigation, engineering machinery and ships. [0003] During the use of the existing plunger pump, in order to avoid damage to the sealing ring due to heat generated by long-term operation, it is necessary to add butter for lubrication after a period of use, so that the plunger pump can continue to work normal...

AI Technical Summary

Problems solved by technology

The existing method of adding butter is generally to directly use the oiling tool to add butter after the plunger pump has been working for a specified time, or directly install a butter cup on the plunger pump, and add butter in the butter cup to reach the column. During the operation of the plunger, there is always lubricating oil to keep it lubricated, but the existing way of adding butter is relatively cumbersome. Once the butter is added, it needs to be shut down, affecting the work progress, or complicating the structure of the plunger pump, which further increases the plunger pump.
