rotary vane vacuum pump

The eccentrically mounted rotor in the pump is tangent to the fixed surface of the stator, and two (or more) rotary vane slide in the rotor groove (usually radial) and are in contact with the inner wall of the stator, dividing the pump chamber into several variable-volume rotary variable-volume vacuum pumps.Usually, the gap between the rotary vane and the pump chamber is sealed with oil, so rotary vane vacuum pumps are generally oil-sealed mechanical vacuum pumps.

A vacuum unit is a device composed of a vacuum pump, a vacuum gauge, a vacuum valve, a vacuum pipe and a control element, which can obtain different vacuum degrees.

Summarize
One of the basic devices used to remove gas from a closed container. It can be used alone, or as a booster pump, diffusion pump, molecular pump before the use of pump. This series of pumps are widely used in metallurgy, machinery, electronics, chemical, petroleum, medicine and other industries of vacuum smelting, vacuum coating, vacuum heat treatment, vacuum drying and other processes.

The 2XZ rotary vane vacuum pump is the basic equipment used to remove gas from sealed containers.It can be used alone or as a pre-stage pump for booster pumps, diffusion pumps, molecular pumps, maintenance pumps, and titanium pumps; this series of pumps has the advantages of low sound, no oil return when the pump is stopped, and easy to start. The pump is equipped with an air ballast valve, which can remove a small amount of condensable steam.This vacuum pump cannot remove excessive oxygen content, corrosive, explosive or toxic (except for 2XZFL explosion-proof rotary vane vacuum pumps), and gases containing fine particles of dust, nor can it be used as compression pumps or air delivery pumps.

Summarize
The JZJS(Y) series Roots water (liquid) ring unit is a pumping system composed of a ZJ-type Roots vacuum pump as the main pump and a two-stage water ring pump as the pre-stage pump. In addition to general gases, it can also be used to suck gases containing moisture or a small amount of dust.Compared with ordinary water ring vacuum pumps, it has the characteristics of high vacuum and high pumping speed under high vacuum conditions.Therefore, it is an ideal vacuum acquisition equipment for drying, dehydration and vacuum waste gas treatment processes in textile, food, chemical and other industries.

The XD series rotary vane vacuum pump is a type of vacuum pump with a relatively complete design that can operate at any inlet pressure.Therefore, it has a wider range of applications than conventional rotary vane vacuum pumps. Currently, this type of pumps is widely used for vacuum packaging of various types of food products, forming vacuum blisters in the rubber and plastic industries, transporting paper in the printing industry, vacuum impregnation and sealing of food products. various castings, vacuum fixtures, vacuum drying, vacuum filtration, vacuum dynamic testing and vacuum suction in hospital operating rooms. Vacuum treatment is within the vacuum range that this pump can provide.

Summarize
The JZJX series Roots rotary vane vacuum unit consists of Roots vacuum pump as the main pump and rotary vane vacuum pump as the front pump. The structure is compact and easy to operate. Suitable for pumping air and other non-condensable and non-corrosive gases, widely used in various vacuum systems requiring large pumping speed and high vacuum. Such as: vacuum smelting, power capacitors, transformers, vacuum impregnation treatment, vacuum coating equipment in the pre-pumping.
