ZJP series air-cooled Roots vacuum pump

ZJP series air-cooled Roots vacuum pumpOverview and Principle

The ZJP type Roots vacuum pump with bypass valve is a derivative product of the ZJ type Roots vacuum pump. The pumping principle is the same as that of the ZJ type pump. It also uses a pair of 8-shaped rotors to maintain a certain gap in the pump casing and rotate in the opposite direction at a constant speed to produce suction and exhaust effects. The difference is that the intake and exhaust ports of the ZJP type Roots vacuum pump with a bypass valve are connected, and a gravity valve is vertically installed on the channel between the two. Its function is that when the product of the pressure difference between the intake and exhaust ports and the effective operating area of the valve exceeds the self weight of the valve head, the valve head will automatically open. This value is the highest pressure difference for the reliable operation of the pump, therefore, this valve is actually an overload automatic protection valve, and it is also the biggest advantage of ZJP type Roots vacuum pump with bypass valve.

ZJP series air-cooled Roots vacuum pumpKey Features:

• Oil free and clean, meeting the requirements of various oil-free and corrosive special working conditions
• Overload automatic protection, suitable for high voltage differential working conditions, safe and reliable operation
• High precision, high speed, high efficiency, reduce usage costs, and improve economic benefits
• No leakage, low noise, low vibration, lower operating and maintenance costs
• Stainless steel mechanical seal, with stable sealing performance and long service life.

Application scope:

The advantage of Roots vacuum pump is that it still has a high pumping rate at lower inlet pressures, but Roots vacuum pump cannot be used alone and must be used in conjunction with the preceding vacuum pump. The Roots vacuum pump can only be started when the current level vacuum pump draws the system pressure to the allowable starting pressure of the Roots vacuum pump.

According to different working pressures and process conditions, the front-end vacuum pump of Roots vacuum pump can adopt oil sealed mechanical vacuum pump, liquid ring vacuum pump, reciprocating vacuum pump, etc. The maximum pressure that can be achieved by Roots vacuum pumps after configuring different types of front-end vacuum pumps varies.
