TECHNICAL FIELD

[0002] Oil ring vacuum pump is a kind of equipment that produces vacuum by liquid (usually oil or water) as working medium. The working principle is to use liquid to form annular oil film in pump cavity to seal pump cavity, and discharge gas under the action of pressure difference between inside and outside of pump. Since liquid is involved in operation in pump cavity, condensed water and oil mist often discharge together with gas. In some cases, condensed water and oil may be mixed into emulsion or liquid mixture, which not only affects the efficiency of vacuum pump, but also may cause equipment corrosion, pollution or unable to operate normally. Therefore, oil water separation device is used to clean and recover these condensed liquids to ensure long-term stability of the system.

[0003] At present, the commonly used oil ring vacuum pump unit condensate oil water separation device adopts filtering mode to filter and collect oil and water in gas generated during operation of oil ring vacuum pump unit, then precipitates and stratifies the filtered and collected oil and water, and then separates the stratified oil and water. The step of filtering and collecting oil and water in this mode is relatively cumbersome to use, and is not simple and convenient. In addition, when oil and water are precipitated and stratified, if the external temperature is low, the oil liquid will solidify on the inner wall surface of the oil water separation device, so that the oil liquid is not easy to discharge from the device.

[0004] Therefore, we propose an oil ring vacuum pump unit condensate oil water separation device to solve the above problems. UTILITY MODEL CONTENTS
