Air-cooled Roots Vacuum Pump Construction

Because the series of pumps are processed by NC machining center, O-ring seals are used between the pump body, the two side caps and the two end caps. The cylindrical pins are positioned, and the parts are interchangeable and easy to maintain. Roots pump can not be used alone, only series front pump can be used.

Different vacuum pumps can be selected as the front pump, such as screw pump, oil seal pump, liquid ring pump, etc. It is worth mentioning that when screw pump and liquid ring pump are used as the first stage pump, they are especially suitable for the occasion where a large number of suspicious gases need to be removed.hot-sale-double-stage-rotary-vane-vacuum-pump

The company's patented technology is used in the dynamic seal part, and the imported oil seal is used to control the jump of the shaft seal less than 0.02mm, so there is no oil leakage at the shaft seal part. A self-weight valve is installed between the intake and exhaust ports of the pump. Its function is to open the valve automatically when the pressure difference between the exhaust ports and the intake ports exceeds the self-weight of the valve. This pressure difference is the pressure difference that the pump can operate reliably. Therefore, Roots pump with relief valve has the function of automatic overload prevention.Energy-saving-rotary-vane-vacuum-pump
