vacuum unit

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
Screw type oil-free mechanical vacuum pump, also known as dry screw vacuum pump, is the use of gear transmission synchronous reverse rotation of the mutual mesh without contact with the left screw and the right screw for high-speed rotation, the use of pump shell and mesh helix will be separated into a number of Spaces, the formation of a number of stages, the gas in the equivalent of each groove (cylindrical pitch) for transmission movement. The two screws are finely balanced, supported by bearings, and installed in the pump shell. There is a certain gap between the screw and the screw, and the screw and the pump body. There is no friction between the pumps when they work, smooth operation, low noise, and no lubricating oil in the working chamber. It can completely replace oil-sealed mechanical pump and water-sealed mechanical pump to become a new generation of main vacuum acquisition equipment.

Summarize
JZJWLW series Roots oil-free vertical vacuum unit is composed of ZJ type Roots vacuum pump as the main pump and oil-free vertical vacuum pump as the front pump pumping system, which is the trend of vacuum industry in the new century, designed and manufactured for our company and customers to pursue environmental protection, high efficiency and recyclable goals.

Summarize
JZJH, JZJ2H series of Roots slide valve vacuum unit is composed of Roots vacuum pump as the main pump and slide valve vacuum pump as the front pump pumping system. It has compact structure and convenient operation. 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, pre-pumping in vacuum coating equipment.

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.

Summarize
JZJG/JZJGP series Roots screw dry vacuum unit is a dry oil-free vacuum unit composed of ZJ type Roots pump as the main pump and NEG/NEGP series screw vacuum pump as the front pump. After the first stage screw vacuum pump works, the vacuum gauge and vacuum relay control the starting of Roots pump.

Summarize
JZJP series Roots water jet vacuum unit is composed of ZJ type Roots pump as the main pump, and all-plastic horizontal water jet vacuum pump as the front pump to form an pumping system, which can remove corrosive gases. The unit is widely used in vacuum drying, vacuum steam room, vacuum concentration and other processes, and is widely used in metallurgy, petrochemical, paper making, food, electronics industry.
