ZW Series LPG Compressor with Oil Pump Lubricating
ZW series of liquefied petroleum gas recycle compressor is vertical, single acting, air-cooled, oil-free lubrication, reciprocating piston unit. This series compressor cylinder & packing components are oil-free to ensure the purity of its working medium. Crankshaft, connecting rod, crosshead components are pressure lubrication (Oil Pump lubrication) to ensure the reliability of lubrication.
Characteristics
Safety and Reliability This unit adopts the optimistic design and corresponds to the standard of JB/T8052-96 “Non-oil lubrication LPG Cycling Compressor” and reaches the level of quality product. It is of energy saving equipment and installed with double anti-“liquid punch” device to secure its smooth running and eliminate the “cylinder cover burst out” accident.
Low Investment Since its complement, energy saving and excellent performance, especially no need to install the additional inlet separating tank and outlet buffer tank, and the related change-over valve and their pipeline and accessories, it saves the customers lots of cost.
High Recovery Rate The cost from the recovering the residual liquid and remained gas will enable the customer to regain the value of the unit in short time.
