The correct choice of Schindler vacuum pump needs attention
1. The working pressure of Schindler vacuum pump should meet the ultimate vacuum and working pressure requirements of vacuum equipment. For example, a vacuum drying process requires a working vacuum of 10 mmHg, and the vacuum degree of the selected vacuum pump should be at least 2 mmHg, preferably up to 1 mmHg. The ultimate vacuum of the pump is usually chosen to be half an order of magnitude higher than the vacuum of the vacuum equipment.
2. Correctly select the working point of the Schindler vacuum pump. Each pump has a certain working pressure range, such as: 2BV series water ring vacuum pump working pressure range 760mmHg ~ 25mmHg (absolute pressure), in such a wide pressure range, the pump's pumping speed changes with pressure (details refer to the pump) The performance curve), its stable working pressure range is 760~60mmHg. Therefore, the working point of the pump should be selected within this range, and it should not be allowed to work for a long time at 25~30mmHg.
3. Schindler vacuum pump should be able to remove all the gas generated during the process of vacuum equipment under its working pressure.
4. Combine the Schindler vacuum pump correctly. Since the vacuum pump has selective pumping, sometimes a pump cannot meet the pumping requirements, and several pumps need to be combined to complement each other to meet the pumping requirements. For example, a titanium sublimation pump has a high pumping speed for hydrogen.
But can't twitch, and the three-pole sputter ion pump,
(or a two-pole asymmetric cathode sputtering ion pump) has a certain pumping speed for argon, and the combination of the two will result in a better vacuum of the vacuum device. In addition, some vacuum pumps cannot work at atmospheric pressure.
Pre-vacuum is required; some vacuum pump outlet pressure is lower than atmospheric pressure, and the foreline pump is required, so the pump needs to be combined.
5. Requirements for oil pollution from vacuum equipment. If the equipment is strictly required to be oil-free, you should choose various oil-free pumps, such as: water ring pump, molecular sieve adsorption pump, sputter ion pump, cryopump, etc. If the requirements are not strict, you can choose to have an oil pump, plus some oil proof
Contamination measures, such as the addition of cold traps, baffles, and oil traps, can also meet the requirements for clean vacuum.
6. Understand the composition of the gas to be pumped. The gas contains no condensable vapor, no particle dust, and no corrosiveness. When selecting a vacuum pump, you need to know the gas composition and select the appropriate pump for the pumped gas. If the gas contains vapors, particulates, and corrosive gases, consider installing auxiliary equipment such as condensers, precipitators, etc. on the inlet piping of the pump.
7. How does the oil vapor from the Schindler vacuum pump affect the environment?
If the environment does not allow contamination, you can choose an oil-free vacuum pump or discharge the oil vapor to the outside.
8. The vibration generated by Schindler vacuum pump during operation has no effect on the process and environment. If the process does not allow, choose a vibration-free pump or take anti-vibration measures.
9, Schindler vacuum pump price, operation and maintenance costs.
