Problems solved by technology

[0002] At present, in order to improve the service life of the mining roller cone bit, the bearing of the roller cone bit needs to be lubricated. In the prior art, oil is injected into the inner cavity of the roller cone bit bearing, and vacuum oiling can better avoid Moisture and impurities enter the inner cavity of the bearing. The vacuum oiling device in the prior art first uses a vacuum pump to evacuate the inner cavity of the bearing when injecting oil, and then injects oil in a vacuum state. It is easy to be sucked into the pipeline of the vacuum pump. When injecting oil in a vacuum state, the injected oil is easy to be sucked into the vacuum pump pipeline. The vacuum oil injection system using the traditional oil nozzle is used to avoid the above problems. A vacuum control valve and an oil inlet control valve are set in the system. , making the entire system complex and cumbersome to operate

Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The invention provides a vacuum grease nozzle, comprising:

[0043] A valve body with a hollow cavity, the hollow cavity includes an upper cavity and a lower cavity connected with each other, the inner diameter of the upper cavity is larger than the inner diameter of the lower cavity, and the bottom end of the valve body is a connector for connecting the oil injection pipe;

[0044] The spool pierced through the hollow cavity of the valve body, the spool is hollow, the top end is provided with an upper joint for connecting the vacuum device, and the bottom end is provided with a low...

Abstract

The invention relates to the field of oil injection equipment, in particular to a vacuum oil injection mouth, a vacuum oil injection system and a vacuum oil injection method. According to the vacuum oil injection mouth, a cavity of a valve core is a vacuumizing channel, an oil inlet channel is arranged on a valve body, the oil inlet channel is in a closed state during vacuumizing, oil cannot be injected into a vacuum pump pipeline in a pumping mode, and when oil is injected in a vacuum state, due to the fact that the vacuumizing channel and an oil injection channel departs from each other, oil cannot be injected into the vacuum pump pipeline in a pumping mode. The vacuum oil injection system is simple in structure and convenient to operate.
