The screw rotor, which is the core part of the vacuum pump, is designed and solved by using three-dimensional surface mathematical model. The solid of the model is processed on the five-coordinate CNC equipment. It has high precision, reliable quality and stable performance, and ensures the long-term trouble-free operation of the product.
This product has independent innovation, strong market competitiveness in product quality and price. It can replace imported products in a wide range and has a large market demand. It will cover more than 100 fields such as chemical industry, metallurgy, electronics, petroleum, aerospace, tools, paper making, packaging, food and information engineering, bioengineering and microelectronics. Noodles replace vacuum equipment with low technology content.
The harm of scale produced by screw vacuum pump:
Because the working medium of screw vacuum pump (i.e. supplementary liquid) is mainly to directly use tap water or paper white water. Because of the high hardness of tap water and the complexity of metal ions in white water, scales will be formed after long-term physical and chemical processes when the internal fluid components of vacuum pump work in this medium. The scale produced will affect the normal operation of screw vacuum pump. After scaling, the pumping rate of screw vacuum pump will decrease. Because there are scales between impeller blades and on the intake and exhaust windows, the volume of the sealed chamber is obviously reduced, and the volume of the intake and exhaust gases is naturally reduced. When the fouling almost fills the space between the blades or the intake and exhaust windows are almost filled with fouling, the intake and exhaust volume is almost zero, and the vacuum pump loses the function of extracting vacuum.
Screw vacuum pump in sewage treatment of selection:
Sewage treatment is now necessary for major factories and enterprises, and its use will also reduce water pollution. Choosing a screw vacuum pump to work in sewage treatment can effectively increase the efficiency of water delivery, but in the selection, attention should be paid to the selection of suitable equipment, otherwise it will increase the difficulty in this regard. Screw vacuum pumps are widely used in sewage treatment plants to transport water, wet sludge and flocculant liquids because of their variable transmission, strong self-priming ability, reversibility and ability to transport liquids containing solid particles.
Screw vacuum pump method of maintaining:
Check the loosening of the screw vacuum pump pipeline and joint. Turn the vacuum pump by hand to see if it is flexible.
Check the wear condition of the sleeve regularly, and replace it in time after the wear is serious.
Start the motor. When the screw vacuum pump is in normal operation, open the outlet pressure gauge and the import vacuum pump, and see that it shows the appropriate pressure.
Open the gate valve and check the motor load at the same time.
To stop the screw vacuum pump, first close the gate valve and pressure gauge, and then stop the motor.
