Pharmaceutical, chemical, semiconductor and other enterprises with higher requirements for clean vacuum, the demand for screw vacuum pump is greater. In the purchase of the equipment, we generally pay more attention to the equipment how much this problem, in fact, usually in the thousand yuan or so, mainly by the brand and performance of the impact.
Screw vacuum pump brand
Different brand of screw vacuum pump, of course, the price will be different, because the brand is different, so in many aspects, such as awareness, word of mouth there is different, many consumers will buy brand manufacturers products, this is because the brand manufacturer of higher product quality, service better, of course the price will be relatively higher.
Screw vacuum pump performance
Products in the usual use process, for the performance requirements are very high, any performance defects should not be used in the practice of production, only high performance to obtain consumer recognition, and the price of high performance of course will be relatively high.
The following to introduce the high cost – effective dry screw vacuum pump, for your reference.
Using a pair of screw, made in the vacuum pump shell synchronous high-speed reverse rotation to produce suction, exhaust system of extraction equipment. In the process of the usual work,
We call it the improved version of oil seal type vacuum pump.
Screw vacuum pump advantages:
1, no oil design, no oil consumption, no drip and leakage defects.
2. Anti-corrosion coating is added on the outside and inside of the body of the vacuum pump, which can better adapt to the environment than oil seal.
3. There is no gas compression in the vacuum pump, so condensable gas can be extracted.
4. The structure is not complicated and the maintenance operation is simple.
5. Environmental friendly and convenient.
Screw vacuum pump loss analysis:
Because 1, the vacuum pump will feed medium containing SO ₂, water, etc. Can be combined to generate, corrosive material to prevent corrosion damage by the vacuum pump components, the rotor and the vacuum pump cavity surface coating corrosion resistant coating.
2. Failure of solid particles or dust. Check the vacuum pump inlet equipment carefully before operation.
3. Damage analysis of colloidal carbon. The entrance contains Ee, C, O, etc., which are polymerized substances such as butadiene and sulfoxide adhering to the pipe. If the substance adheres to the vacuum pump chamber and rotor surface, it will destroy the surface coating of the equipment and cause damage to the vacuum pump.
4, the vacuum pump in the process of high-speed operation, bearing will produce normal heat.
5. Bearing damage. Bearing roll and bearing retainer damage after the bearing overheating, bearing damage should be replaced in time.
6, the bearing preload strength is large, this time will make the bearing clearance cut or no clearance, resulting in the bearing heating.
7, vacuum pump equipment jitter influence, when the vacuum pump body or bearing jitter abnormal bearing temperature will occur too high, carefully check to find out the reason, solve the abnormal temperature normal.
8, when there is a valve plate cracking, the pressure on both sides of the impeller produces unbalanced force, then the rotor will produce axial force, heavier bearing load, continuous operation will make the bearing temperature rise. Encountered this situation, the need to replace the valve plate in time.
If possible, kindly suggest please your working industry/process, working pressure, working medium, etc. Given detailed request helps to gain better-matched customized solution. Thanks for your patience.
