The advantages and disadvantages summary - dry screw vacuum pump

dry screw vacuum pump is mainly using screw pair, is characterized by two screw through the dynamic equilibrium in the balance, and is supported by bearings, is installed in the water pump shell, and there is a certain gap between screw and screw, thus made the dry screw vacuum pump. In the process of work, there is no friction between each other, smooth running, low noise, no lubrication in the studio, and dry screw pump can remove dust contains a lot of water vapor and a small amount of gas, and have the highest vacuum degree is higher. However, China's use of screw pump is mainly rely on imports, the price is very expensive.

dry screw vacuum pump, it will use a pair of screw pump suction and discharge pump out of shell, in order to simultaneously reverse rotation at a high speed. Its advantages to make up for the deficiency of the oil seal vacuum pump, we call it the updated version of oil seal vacuum pump. However, the cost of dry screw vacuum pump and its shortcomings. Next, this paper mainly introduces its advantages and disadvantages:

the advantages of the dry screw vacuum pump 1, the working chamber and the screw rotor surface shall be corrosion resistant coating, can adapt to the harsh conditions

2, gas compressed in the pump, not suitable for the extraction of condensable gas

3, no fuel consumption, no drip

4, simple structure, easy to maintain.

5, the gases pumped directly from the pump body, do not pollute the water, there is no pressure environment, easier to recycle gas.

the disadvantages of the dry screw vacuum pump

1, because of the screw pump and processing difficulties, the screw water pump used in our country mainly rely on imports, the price is very expensive.

2. Not suitable for pumping explosive gas.

3, too much is not suitable for removing oxygen gas.

with the development of Chinese industry, manufacturing and processing in the semiconductor industry, liquid crystal display and so on, more and more high to the requirement of clean vacuum environment, the traditional oil vacuum pump has not satisfy this requirement. The screw type dry vacuum pump has a wide speed range, simple and compact structure, suction cavity parts without friction, long life, low energy consumption, the advantages of no pollution, has more advantages in the field of manufacturing and application. Vacuum pump market plays an important role. In developed countries such as Europe and the United States and Japan, dry screw vacuum pump in many areas has gradually replaced the traditional oil pump.

The importance of water pump has increased as pool cover drain pump have become a must in our daily life.

Overwhelming customers with too much information or the slew of benefits water pump provides–even if they're all valid–is a surefire way to lose their attention.
But we do think that reckoning with supply chains of water pump is a really important step. Even super simple switches in material, or sourcing, or shipping, or worker benefits seems like good place to start.
