vacuum pump

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.

Generalize
SZ, 2BV type single-stage liquid ring vacuum pump is a horizontal direct connection type.The whole pump consists of an intake and exhaust pump cover, an intake and exhaust disc, a pump body, a mechanical seal and an impeller.This series of vacuum pumps has the advantages of compact structure, easy installation and maintenance, and is mainly suitable for vacuum filling, vacuum sterilization, vacuum forming, vacuum concentration and other processes.

Summarize
2BV, 2BV2 single-stage liquid ring vacuum pump is horizontal direct connection type. The whole pump is composed of intake and exhaust air pump cover, intake and exhaust disc, pump body, mechanical seal and blade. This series of vacuum pump has the advantages of compact structure, convenient installation and maintenance, and is mainly suitable for vacuum filling, vacuum sterilization, vacuum forming, vacuum concentration and other processes.

Summarize
WLW-B.F.T is oil-free (corrosion-resistant) vertical reciprocating vacuum pump is our company and research units jointly developed, continuous improvement of mature products, is to replace the W-type horizontal reciprocating vacuum pump ideal products, compared with the W-type horizontal reciprocating vacuum pump has the following advantages:
1. Energy saving (33%), water saving (50%), and floor space saving (66%).
2. No oil lubrication, can obtain clean vacuum, and facilitate the clean recovery of exhaust gas.
3. Air valve axial device, long service life (4-10 times).
4. Low vibration, low noise.

Summarize
The channel between the two stages is composed of an intermediate disc and a connecting pipe, the rotating part is composed of a shaft and a two-stage impeller, and the fixed part is composed of an inlet and outlet pump cover, two pump bodies, an intake disc and a bearing bracket. The motor and pump parts of the drive are connected by a coupling, and the pump and motor are mounted on a common base. The pump has double stage action and high limit vacuum. Separate design, stable and reliable operation, mechanical seal, to ensure a clean working environment, low vibration, low noise, suitable for a wide range of industrial fields.

Summarize
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.

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.

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.
