How to choose the advantages of vacuum plasma vacuum pump unit _

vacuumizing speed is to determine the vacuum plasma cleaning machine working efficiency is one of the important factors. Dust collection speed is mainly decided by the vacuum pump. When it comes to processing products of size is large, with large cavity must be used ( More than 80 l) Vacuum plasma cleaner. If only the use of a vacuum pump, vacuum speed will slow down, and the time needed for vacuum will be very long. Therefore, cavity vacuum plasma cleaner is usually equipped with vacuum pump in order to improve the speed of vacuum. Today we will introduce the plasma cleaner used in types of vacuum pump and vacuum pump selection set of considerations.

vacuum pump combination of two or more of the vacuum pump series of structure, can greatly accelerate the speed of vacuum pump to send. In vacuum plasma cleaner usually use three types of vacuum pump group, is a kind of rotary vane vacuum pump and roots pump; The other is a dry vacuum pump + roots pump; The last is a mechanical pump and molecular pump.

1。 Rotary vane vacuum pump + roots pump

rotary vane vacuum pumps and composed of roots pump pump can also be referred to as the pump group. This pump group is one of the most common pump in our vacuum plasma cleaning machine group. It is driven by rotary vane vacuum pump. and roots water pump as a secondary pump combination. This type of pump group is usually used for vacuum plasma cleaner, including cleanliness requirements is not very tall and cavity is large.

rotary vane vacuum pump and roots pump is the most common pump in the vacuum plasma cleaning machine group. Has many advantages: first of all, it can greatly improve the pumping speed and reduce the vacuum time. Second, the structure is relatively simple, easy to maintain; Third, cost-effective, has the price advantage.

2。 Dry screw vacuum pump + roots pump

dry screw vacuum pump and roots pump dry pumps. Pumps used as pump at the bottom of the dry screw vacuum pump, the use of roots pump as the auxiliary water pump. Because they are composed of dry vacuum pump, so there is no oil pollution, the cleaner is higher than the pump group. Dry pumps are normally used for high cleanliness requirements of the industry, biological medicine, for example, semiconductor and aerospace.

stem pump group has superior performance, has many advantages: a high cleanness, avoid oil pollution; Second, high vacuum speed, improve work efficiency; Three, stable performance, low voice. Fourth, low requirement for working environment, can deal with all kinds of bad working environment.

3。 Mechanical pump and molecular pump

mechanical pump and molecular pump to form a special group - pump Molecular pump group. Molecular pump group can be formed using the clean ultra-high vacuum environment, so the molecular pump group is often used to need high vacuum coating machine and equipment, including etching machine.

molecular pump group is so strong, it have what advantage? First, molecular pump group started quickly, the speed is very fast. Second, do not use the oil molecular pump group, will not cause oil pollution. Third, simple maintenance.
