Welcome to the official website of Changsha Xiangneng Oil Filter Machine Manufacturing Co., Ltd.!

ZJ series vacuum pumping unit


The working vacuum of the unit is ≤ 133Pa, and the limit vacuum that can be reached is ≤ 5Pa. The unit has the characteristics of fast starting, large pumping speed, etc. It can be used for vacuum metallurgy, welding, chemical, petroleum, vacuum devices and other industrial vacuum pumping, especially for the vacuum pumping operation of power equipment such as transformers.



I. Purpose and Functions

Working vacuum of the unit; 133Pa, the limit vacuum that can be reached≤ 5Pa, the unit has the characteristics of fast starting, large pumping speed, etc. It can be used for vacuum metallurgy, welding, chemical, petroleum and vacuum devices and other industrial vacuum pumping, especially for power equipment such as transformers

 

II. Main Features

The unit takes Roots pump as the main pump and the rotary vane vacuum pump as the front pump. An electromagnetic differential pressure valve is connected in series between the front pump and the main pump, which acts with the opening of the front pump

To ensure the reliable operation of the unit, the unit is also equipped with vacuum pump oil circulating filter and circulating water cooling device. Ensure that the unit vacuum pump oil is not aged and the circulating water is kept at the normal operating temperature of the pump. If a larger pumping rate is required, two roots pumps can be equipped to make the pumping speed faster under high vacuum conditions

 

III. Optional Accessories

Germany Robert RBT Ball Valve

Double zone/single zone micro CNC vacuum gauge
