Description

Technical Field

[0001] The utility model relates to the field of diaphragm boxes, in particular to a diaphragm box vacuum pumping and oil injection device. Background Technique

[0002] A diaphragm box is a component used in the industrial field. Its main function is to protect or isolate the internal part of a device, instrument or system, preventing the external environment from affecting it. Diaphragm boxes are usually used in occasions where sealed protection is required.

[0003] At present, when using a diaphragm box, it is necessary to pump vacuum and inject oil into it, which can better lubricate and protect the diaphragm box. However, when pumping vacuum and injecting oil currently, usually the air inside the instrument and equipment is pumped out by a vacuum pump, and then oil is injected into the diaphragm box through an oil injection pump. In this way, before oil injection, air still enters the diaphragm box, resulting in insufficient vacuum degree inside the diaphragm box, and then reducing the effect of vacuum oil injection. For this reason, we propose a diaphragm box vacuum pumping and oil injection device to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a diaphragm box vacuum pumping and oil injection device to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:
