Abstract

The invention provides a pressure plate type lubrication pump convenient to exhaust. The pressure plate type lubrication pump comprises an oil bucket and an oil pumping assembly. The oil bucket is internally provided with a guide rod and is in sliding fit with a pressure plate along the guide rod. The edge of the pressure plate and the inner wall of the oil bucket are slidably sealed. An oil storage space of the lubrication pump is provided with an exhaust channel. Air inlets of the exhaust channel are located in the edge of the pressure plate. The exhaust channel extends towards the center of the pressure plate in the radial direction. According to the lubrication pump, the structures of the pressure plate and the guide rod are subjected to innovative design, the air inlets are formed in the edge of the pressure plate, thus, air in the oil storage space of the lubrication pump can be exhausted out only from the air inlets in the edge of the pressure plate so as to be exhausted completely, and the situation that oil is overflowed the pressure plate can be effectively avoided through the structure that the exhaust channel extends towards the center of the pressure plate in the radial direction. Through the lubrication pump, the problems that gas in an existing lubrication pump cannot be exhausted completely, and oil is discharged are solved, air is automatically exhausted while the oil is injected, and the exhaust effect is good.

Description

technical field

[0001] The invention relates to a mechanical lubricating pump, in particular to a pressure plate type lubricating pump which is convenient for exhausting. Background technique

[0002] In the prior art, when lubricating grease is injected into the lubricating pump with a pressure plate, in order to facilitate the exhaust, an air vent is usually opened on the upper part of the oil drum, or a hole is opened on the pressure plate to connect a coiled hose, and the gas is introduced into the top cover from the inside Vent. Exhausting the grease during grease injection through the existing exhaust method, often part of the grease will be discharged from the vent hole, which especially affects the cleanliness of the environment; moreover, it is difficult to discharge all the gas in the pump, and some of it will remain in the lubrication pump, which is not easy to discharge , affect the use effect of grease, and it is very inconvenient to use.
