2BE type liquid ring vacuum pump and compressor are developed by our company on the basis of many years of scientific research and production experience, combined with advanced technology of similar products in the world. The high efficiency and energy saving products are usually used to suck gases without solid particles, insoluble in water and corrosive in order to form vacuum and pressure in sealed containers.
2BE liquid ring vacuum pump is widely used in papermaking, chemical industry, petrochemical, light industry, pharmaceutical, food, metallurgy, building materials, stone tools, coal washing, mineral processing, fertilizer and other industries.
The single stage rotary vane vacuum pump has two rotary vanes that are eccentrically mounted in the rotor slots in the stator cavity. When the rotor drives the rotary vane to rotate, the rotary vane is pressed against the cylinder wall by the centrifugal force and the rotary vane spring to separate the intake and exhaust ports, and the inlet chamber volume is periodically expanded to inhale, and the exhaust chamber volume is periodically. By the pressure of the compressed gas and the oil pushes the exhaust valve exhaust to obtain a vacuum.
Has been widely used in food vacuum packaging, plastic industry vacuum plastic forming. Printing industry paper transport, vacuum fixtures, and vacuum suction, etc.
Roots Vacuum Pump (Roots Pump) is a kind of rotary varactor vacuum pump. It evolved from Roots blower. According to the different working range of Roots vacuum pump, it can be divided into low vacuum Roots pump with direct air discharge, medium vacuum Roots pump (also known as mechanical booster pump) and high vacuum multi-stage Roots pump.
Roots pump is a common environmental protection equipment, at present, in the food, textile, machinery, electronics industry and other industries have been widely used.
Piston vacuum pump can be used alone or as the front pump of other high vacuum pumps, but it is not used for pumping from one container to another. When extracting excessive oxygen, explosive, corrosive to ferrous metals, chemical reaction to vacuum pump oil, water, dust and other gases, installations should be attached.
It can be widely used in the vacuum impregnation and vacuum drying process of transformers, wires and cables and capacitors in the power industry. Vacuum coating, vacuum smelting, vacuum heat treatment, vacuum oil filtration, freeze drying; Ideal vacuum equipment in aviation simulation test. If there is a small amount of water vapor or dust in the air, the filter should be installed.
How to use oil diffusion pump to obtain ultra-high vacuum? Oil diffusion pump is a kind of pump commonly used in high vacuum system. Ultra-high vacuum can be obtained by some technical measures. Diffusion pump oil with good selectivity At present, high vacuum oil diffusion pump generally uses No. 3 diffusion pump oil, and ultra-high vacuum uses silicone oil. Ultra-high vacuum systems without hydrocarbons are required. Fluorine oil is used in diffusion pumps.
The pumping mechanism of molecular pump is different from that of mechanical pump which depends on the volume change of pump chamber. The principle of momentum transfer is used to make molecule flow directionally and be discharged from the pump, so as to achieve the purpose of pumping.
Application scope covers many fields: analytical instruments, semiconductor industry, optical/glass industry, vacuum coating technology, vacuum metallurgy, leakage detection, scientific research facilities, lighting industry.
It is a kind of suction and exhaust equipment which uses a pair of screw to make synchronous high-speed reverse rotation in the pump shell. The two screw are supported by bearing and installed in the pump shell. There is a certain gap between screw and screw. Therefore, when the pump works, there is no friction between them, smooth operation, low noise and no need to wet the working chamber. Lubricating oil, therefore, dry screw pump can remove a large amount of steam and a small amount of dust gas occasions, the limit vacuum is higher, lower power consumption, energy saving, maintenance-free advantages.
Screw dry vacuum pump is widely used in electronics, nuclear energy, chemical industry, medicine, food industry and other fields.
Dry vacuum pump means that the pump can start pumping from atmospheric pressure, and can discharge the pumped gas directly into the atmosphere. There is no oil or other working medium in the pump chamber, and the ultimate pressure of the pump is the same as that of the oil-sealed vacuum pump. Or close to a mechanical vacuum pump.
For ordinary oil-free vacuum systems, although oil-sealed vacuum pumps can be used with accessories such as cold traps or adsorption traps to prevent backflow, they do not completely solve the problem and make the system complicated. The use of a suitable type of dry vacuum pump can achieve the desired results.
