liquid ring vacuum pumps material requirements

 liquid ring vacuum pump is a kind of equipment that puts the pump body into the water for pumping. Its use is very extensive in our life. However, due to the particularity of its working environment, there are certain requirements for its material. The following is a small series according to the relevant The information is summarized by everyone about the material requirements of the liquid ring vacuum pump:

1. Good chemical stability. The material of the water ring vacuum pump should have strong anti-oxidation and anti-corrosion ability, and does not react chemically with the working medium in the equipment and the gas discharge during the process.

2. The material of the other equipment must have good ductility, mechanical processing performance and welding performance, and it is easy to process into a complex shape shell.liquid-ring-vacuum-pump-in-petrochemical-industry

3. At the working temperature and baking temperature, the saturated vapor pressure should be low enough.

4, to have sufficient mechanical strength and rigidity, so as to ensure that the shell can withstand greater atmospheric pressure, can not be deformed during heating and baking.

5. Under the working vacuum and working temperature, the components inside the vacuum vessel should maintain good working performance.Roots_Vacuum_Pump

6, good thermal stability. Maintains good vacuum and mechanical properties throughout the system's operating temperature range.

7, good air tightness. In operation, it should be kept under a high vacuum environment, so the material of the wall should not have porous structure, cracks or other defects forming leakage, and the permeation rate and outgassing rate should be low.

The material requirements for the liquid ring vacuum pump are the above points, that is to say, the material has a certain strength and stability, and since it is a vacuum device, it requires a good air tightness, so that the device can be further protected.

piston vacuum pump common sense

The sliding piece is embedded in the groove and can slide freely. When the rotation occurs, the sliding piece is sucked onto the pump casing by centrifugation. The sliding plate pump is a volumetric pump, and the adjacent two sliding pieces move to the lower side and the pump. The shell and rotor block the smallest volume, the largest at the top, when the rotor rotates clockwise, the process of the adjacent two slides from the bottom to the top is the volume increase process, so the oil absorption (from the fourth quad to the second Quadrant); from the top to the bottom is the volume reduction process, so the pressure oil (from the second to the fourth quadrant).rotary-vane-vacuum-pumps

Double acting: When the motor drives the rotor to rotate, the sliding piece protrudes outward under the double action of the centripetal force and the pressure oil at the bottom of the sliding piece, and the top is closely attached to the inner and outer parts of the stator. The four sliding vanes on the four-section concentric arc form four sealed working oil chambers with the rotor surface surface, the inner and outer surfaces of the stator and the two distribution plates. These oil chambers change from small to large or large to small as the rotor rotates, and can pass through the oil suction window of the distribution plate (connected to the oil suction port) or the oil discharge window (connected to the oil discharge port). Inhale or pressurize the oil.

During each revolution of the rotor, each working oil chamber completes two oil suction and oil pressure, so it is called double-acting piston vacuum pump. Because the upper and lower pressure chambers are symmetric with each other, the shaft is balanced by force and is unloading.

    The piston vacuum pump is equipped with small power and large flow. It is the best choice for gas stations, oil depots, chemical industry, oil refinery, aviation kerosene and steam refueling.piston-vacuum-pump-structure

Single action: the sliding piece is embedded in the groove and can slide freely. When the rotation occurs, the sliding piece is sucked onto the pump casing by centrifugation. The sliding plate pump is a positive displacement pump, and the adjacent two sliding pieces move to the lower side. The volume with the pump casing and the rotor is the smallest, and the largest at the top. When the rotor rotates clockwise, the process of the adjacent two slides from the bottom to the top is the volume increase process, so the oil absorption (from the fourth quadrant) To the second quadrant); from the top to the bottom is the volume reduction process, so pressurize the oil (from the second to the fourth quadrant).

All drawings are optimized, and innovative new products are developed by using excellent processing equipment.liquid-ring-vacuum-pump-in-salt-production-process

As we all know, Roots vacuum pump and Roots blower are very close in structure and working principle. When it works, the suction port is connected with the main pump of the vacuum vessel or the vacuum system. Roots vacuum pump has many advantages: starting speed is faster than other vacuum equipment, energy consumption is less, pumping speed is larger than other vacuum equipment, efficiency is higher, and it is not sensitive to water vapor and dust contained in the pumped gas, which is very conducive to people's operation.Roots_Vacuum_Pump

At present, Roots vacuum pump has been widely used in vacuum smelting, degassing, rolling, as well as chemical, food and pharmaceutical industries. Although there is a certain gap between domestic and foreign development level of Roots vacuum pump, there is a great development prospect in China's industry, because with the deepening of industrialization, the demand of Roots vacuum pump is constantly increasing and the future is boundless.rotary_vane_vacuum_pump

Oil Sealed Vacuum Pump

Some vacuum processes will produce a lot of dust. If dust is mixed with the pumped gas into the oil seal vacuum pump, it will accelerate the wear of parts in the pump chamber like abrasive, cause wear and damage to the pump rotor and pump chamber, block the oil pipeline or make the pump unable to operate. If dust enters the vacuum valve, the seal will fail and leak out. Therefore, the prevention and filtering of dust has been completed. In order to prolong the service life of vacuum system and improve productivity, dust filter must be used in dusty vacuum system.Roots_Vacuum_Pump

When the dust volume is small, it can be filtered by the pump oil filtration system. But when the dust volume is large, in order to prevent the damage of the vacuum pump and ensure the normal operation of the vacuum pump, the dust collector must be used.rotary-vane-vacuum-pump-in-brewing-industry.

Water ring vacuum pump in fire fighting equipment

Water ring vacuum pump belongs to the category of volume pump. In fire protection, it is matched with centrifugal pumps to drain water for centrifugal pumps.liquid_ring_vacuum_pump

Water ring vacuum pump consists of pump body, pump shaft, impeller, suction port and exhaust port. The cross section of the pump chamber is round, and the impeller is eccentrically arranged in the pump chamber. A certain amount of water is introduced into the pump chamber. By rotating the bias impeller in the pump chamber, the volume of the crescent cavity composed of the water ring attached to the inner wall of the pump chamber and the impeller changes periodically, so as to realize the exhaust and water diversion. When the impeller is in a static state, the water is in the lower part of the pump chamber. When the impeller drives the water to rotate, due to centrifugal action, the water is thrown around by the impeller, forming an equal thickness water ring attached to the inner surface of the pump chamber. The crescent cavity formed between the impeller surface and the water ring consists of several chambers with different volumes. Because the impeller is installed eccentrically, the volume of each chamber increases and decreases periodically with the rotation of the impeller, and the gas pressure in each chamber decreases and increases accordingly. When each chamber rotates through the suction and exhaust ports, it automatically realizes the functions of suction, compression and exhaust due to the effect of pressure difference, so that the centrifugal pump can discharge air and start water diversion and drainage.rotary-vane-vacuum-pumps

The water ring pump has the advantages of simple structure, reliable operation, uniform suction, small wear and tear, and long service life. The disadvantage is to add water to the shell before starting. Water storage tanks need to be installed, occupying a larger space. In severe winter, attention should be paid to prevent the freezing of water in the tank.vacuum-pump-vacuum-distillation
