    Roots Pumps Systems With Rotary

    Model:ZJP1200/H-150


    Use:
    Roots pump systems with rotary piston pumps have features of obvious effect of saving energy, high vacuum and high pumping speed in high vacuum. It is widely used for transformer and electrical wire of electric utility industry, vacuum soaking and vacuum drying of capacitor. It is a perfect vacuum equipment of vacuum coating,vacuum smelting, vacuum heat treatment, vacuum filtering oil, vacuum cooling and drying. If it is used for pumping the gases mixed with a little vapour and dust, it is necessary that a filter is fitted in the gas inlet pipe.

     


    Structure and Features
    Roots pump is used as main chief pumps, rotary piston pump is as backing pump. They are connected in series. By the vacuum electric relay and electricity trigger manometer, roots pump and rotary piston pumps own some features of start and stop automatically, automatic protective overload function. The system is installed on the chassis. Equip pipe, valve, electric control box, cooling water pipe,
    According as cubage of the pumped system and the ultimate pressure, the ratio of the nominal pumping speed between the pump and other pump is the range between 4:1 and 10:1. The front is suitable for bigger vacuum system and operated for long time with the lower inlet pressure or ultimate pressure. In order to preventing that the oil return to the system, it is equipped an electromagnetic vacuum break valve on the gas inlet pipe of the rotary piston pump. Its action and the motor of rotary piston pump carry out linkage. When the rotary piston pump is stopped, solenoid vacuum break valve charge the inlet port of pump with gas, ensure oil return to oil box from the pump housing and avoid vacuum oil polluting vacuum system.
    There are designs as follow according as different ultimate pressure.
    ●A Roots pump systems with single stage rotary piston pump
    ●A Roots pump systems with double stage rotary piston pump
    ●Two Roots pump systems with single stage rotary piston pump
    ●Two Roots pump systems with double stage rotary piston pump
