Product Description

OEM ODM Service 380V 5.5kw Silent Piston Oil Free Reciprocating Vacuum Pump
 

Product Description

A reciprocating vacuum pump (also known as a piston vacuum pump) is one of the low vacuum acquisition equipment. Its limited pressure is generally between 1330 and 2660Pa, and its pumping speed range is relatively large, from 50L/S to 600L/S. It is suitable for vacuum impregnation, steel vacuum treatment, vacuum distillation, vacuum evaporation in industries such as petroleum, chemical, pharmaceutical, food, light industry, metallurgy, and electrical engineering. Vacuum concentration, vacuum crystallization, vacuum drying, vacuum filtration, and vacuum operation of concrete to remove gases. Reciprocating vacuum pumps are not suitable for extracting gases with high oxygen content, explosive properties, corrosive properties on metals, or gases containing particulate dust. They are also not suitable for transporting gases from one container to another as delivery pumps.

The working principle diagram of a reciprocating vacuum pump is shown in the figure. The main components of the reciprocating vacuum pump are cylinder 1 and piston 2, which moves in a reciprocating straight line. The drive of the piston is completed by a crank connecting rod mechanism 3 (including a crosshead). In addition to the main components mentioned above, there are also important components such as exhaust valve 4 and suction valve 5, as well as auxiliary components such as the base, crankcase, dynamic seal, and static seal.

WLW vertical oil-free (corrosion-resistant) reciprocating vacuum pump is the upgraded product to replace  W horizontal vacuum pump,and the principal equipment to obtain rough vacuum. As adopt the full sealing device, it realizes the complete isolation of the crankcase from the cylinder; in addition, self-lubricating materials are used for piston ring to achieve the advanced oil-free lubrication.Since no sewage is discharged  this type of vacuum pump is especially suitable for the vacuum distillation, vacuum evaporation, vacuum drying, vacuum concentration, vacuum impregnation and other processes in chemical, medicine, food and other industries.
