vacuum pump

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.

H/2H series slide valve vacuum pump is one of the vacuum acquisition equipment for removing general gas and containing a small amount of condensible gas (using gas ballast device). Additional devices should be added to ensure normal use when removing gases with excessive oxygen content, explosive gases, corrosive to ferrous metals, and chemical reactions to pump oil.

This product is one of the main vacuum equipment for obtaining coarse vacuum. It is widely used in chemical, food, building materials and other departments, especially in vacuum crystallization, drying, filtration, evaporation and other processes.

WLW series oil-free vertical reciprocating vacuum pumps produced by the company have been widely used in pharmaceutical, chemical, food and other industries of vacuum transport, extraction, steaming, concentration, vacuum packaging, drying, gas analysis, tail gas recovery and other occasions.

The product is mainly used in the process of coarse vacuum and large extraction volume. Mainly used to remove air and other non-corrosive, insoluble in liquid, containing a small amount of solid particles of gas, in order to form a vacuum in a closed container. A small amount of liquid is allowed to mix in the suction gas.
The pump is widely used in machinery, pharmaceutical, food, petrochemical and other industries.

ZJ, ZJB type Roots vacuum pump is a rotary variable displacement vacuum pump, also known as mechanical booster pump, is currently obtained in the middle and high vacuum of one of the main pumping equipment, its working principle is similar to Roots blower, is the use of two "8 "type rotor, synchronous rotation in the pump housing, from and complete the suction and exhaust.
The difference between ZJB type with relief valve Roots vacuum pump and ZJ type Roots vacuum pump is that ZJB type pump inlet and exhaust are connected, and a self-weight valve is installed vertically on the channel, which is used to keep the pressure difference between exhaust and intake in a controllable value, which is the maximum pressure difference allowed when the pump can be operated. Therefore, this valve is actually an overload automatic protection valve.

Summarize
Variable pitch screw vacuum pump is the use of gear drive 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 to separate the spiral groove into a number of Spaces, the formation of a number of stages, the gas in the various grooves (column deformation 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
ZJ -B Roots vacuum pump is a rotary variable volume vacuum pump, also known as mechanical booster pump, is currently obtained in the middle and high vacuum one of the main pumping equipment, its working principle is similar to Roots blower, is the use of two "8 "type rotor, synchronous rotation in the pump housing, so as to complete the suction and exhaust.
The difference between ZJB -B type with relief valve Roots vacuum pump and ZJ -B type Roots vacuum pump is that the ZJB -B type pump inlet and exhaust are connected, and a self-weight valve is installed vertically on the channel, whose role is to keep the pressure difference between the exhaust and the intake in a controllable value, which is the highest pressure difference allowed when the pump operates reliably. Therefore, this valve is actually an overload automatic protection valve.
