Liquid Ring Vacuum Compressor Selection

In fact, the realization of technological process often has a great relationship with the adaptability of equipment. Therefore, the selection of appropriate type and design requirements of water ring vacuum pump is an important prerequisite for completing production tasks and achieving good benefits. The following points are summarized for you:

1. The working pressure should meet the requirement of the limit vacuum and working pressure of the equipment.

2. Choose the working point of the equipment correctly. Each pump has a certain range of working pressure.

3. Under its working pressure, the equipment should be able to discharge all the gas produced in the process.

4. Correct combination. Because the equipment has selective air pumping, sometimes the selection of one equipment can not meet the requirements of air pumping, and several combinations are needed to complement each other to meet the requirements of air pumping.

5. Understand the requirements of equipment for oil pollution. If the equipment is strictly oil-free, we should choose all kinds of oil-free types; if the requirements are not strict, we can choose oil, plus some anti-oil pollution measures, such as refrigeration trap, baffle, oil trap, etc., can also meet the requirements of clean vacuum.

6. Understand the composition of the exhausted gas. The gas contains no condensable vapor, particulate dust, corrosion and so on. Select the appropriate pump for the exhausted gas. If the gas contains vapor, particles, and corrosive gases, it should be considered to install auxiliary equipment such as condenser, dust collector in the intake pipeline of the pump.

7. How does the oil vapor discharged from the equipment affect the environment? If the environment is not allowed to be polluted, oil-free ones can be chosen, or oil vapor can be discharged outdoors.

8. Whether the vibration caused by the working equipment has an impact on the process and environment. If the process is not allowed, vibration-free pumps or anti-vibration measures should be selected.

Above is the key point of water ring vacuum pump selection. In addition, according to the actual situation, we also need to consider equipment operation and maintenance costs, and ultimately choose a suitable equipment.
