ZJB Roots Vacuum Pump Overview

ZJB type roots vacuum pump is a rotary variable volume vacuum pump, also known as mechanical booster pump. It is one of the main air extraction equipment for obtaining medium and high vacuum at present. The "8"-shaped rotor rotates synchronously in the pump casing to complete the suction and exhaust.

 

The difference between ZJB type roots vacuum pump with over flow valve and the ZJ type roots vacuum pump is that the inlet and exhaust ports of the ZJB type pump are connected, and a deadweight safety valve is installed vertically on the channel. The pressure difference is always maintained within a controllable value, which is the maximum pressure difference allowed for the pump to operate reliably. Therefore, this valve is actually an overload automatic protection valve.

 

ZJB Roots Vacuum Pump Application

  • Vacuum degassing, vacuum melting, vacuum surface treatment for metal and non-metal material industries.

  • Manufacturing of electrical equipment, vacuum freeze-drying equipment, etc.

  • After the pump is configured in series with a liquid ring vacuum pump, it is more suitable for vacuum polymerization, vacuum reaction, vacuum decomposition in chemical industry and vacuum distillation, vacuum drying, vacuum crystallization and other technological processes in the food industry.

     

    ZJB Roots Vacuum Pump Features

    • It can have a large pumping speed in a wide pressure range.

    • The pump chamber is free of oil, which prevents oil vapor from polluting the vacuum system.

    • Small vibration and low noise.

    • The mechanical friction loss is small, so the driving power is small.

    • Easy to maintain and repair, low cost and long working life.

    • Suitable for sudden deflation of vacuum system.

    • It can extract condensable gas.

    • It cannot be used alone, and must be used together with the backing It is not allowed to start under atmospheric pressure, and it can be started only when the backing pump has pumped the inlet pressure of the roots pump to the allowable starting pressure. The backing pump is generally an oil-sealed mechanical pump, a liquid ring vacuum pump.

    • Using unique processing technology, the spare parts are interchangeable.

    • The gas circulation part can be treated with electroless nickel plating, infiltration of Hastelloy, sprayed with Polytetrafluoroethylene (PTFE), Ethylene Chlorotrifluoroethylene Copolymer (ECTFE) and made of stainless steel, which can resist various acids and alkalis, organic solvent corrosion.

    • The single-sided mechanical seal can completely eliminate the long-standing problems such as vacuum leakage and lubrication oil leakage caused by the wear of the shaft dynamic seal.

      Note

      • Ultimate vacuum refers to the minimum partial pressure measured at the pump inlet under the combination of the recommended backing pump after fully pumping without any additional container, and the pump port is sealed without air.

      • The performances in the above table are obtained under the condition that the recommended backing pump is used together. Users can choose different backing vacuum pumps according to different situations, but their main performance indicators will vary.

      • Color, motor voltage can be customized according to requirements.
