ZJ series air-cooled Roots reciprocating pump vacuum unit

ZJ series air-cooled Roots reciprocating pump vacuum unitProduct Overview

It is a vacuum acquisition unit with Roots vacuum pump as the main pump and oil-free reciprocating vacuum pump as the front-end pump. This unit uses an electric contact vacuum gauge (or pressure transmitter) and an electrical control system to achieve automatic start and stop of Roots vacuum pumps and reciprocating vacuum pumps, as well as automatic overload and overheating protection; A complete set of vacuum acquisition equipment that automatically controls various instruments and valves.

A reciprocating vacuum pump is a type of vacuum pump that uses the reciprocating motion of the piston to periodically change the working volume of the pump chamber (cylinder) for pumping, also known as a piston vacuum pump. The structure of a reciprocating vacuum pump is similar to that of a reciprocating piston compressor. During operation, the suction pipe is connected to the evacuated container, and the exhaust pipe is directly connected to the atmosphere. A reciprocating vacuum pump is a low vacuum acquisition device used to extract gas from containers with an internal pressure equal to or lower than one atmosphere.

The old-fashioned reciprocating vacuum pump has a horizontal structure, which has many disadvantages. Therefore, the reciprocating vacuum pump with a horizontal structure has been basically eliminated. The new structure is a vertical structure, which has significantly improved the performance and reliability of the reciprocating vacuum pump after improvement. However, the reciprocating vacuum pump still has the disadvantage of a certain failure rate.

It is a rotary variable volume vacuum pump that requires a front-end pump to be used in a wide pressure range, has a high pumping speed, and is insensitive to dust and water vapor in the extracted gas. Widely used in industries such as metallurgy, chemical, food, and electronic coating. Mainly used as the main pump for vacuum units, it requires the assistance of a front-end pump. For example: water ring vacuum pump, slide valve vacuum pump, vertical oil-free vacuum pump, molecular vacuum pump, etc. The domestic Roots vacuum pump maintains a record of 20000L/S.
