Dry vacuum pump In operation, we must operate according to the correct steps to achieve good results. If the operation is wrong, it will cause all sorts of troubles. It is also very important to purchase qualified products. Let's learn about it together. Dry vacuum pump What are the points of attention when purchasing?
The limit pressure of dry vacuum pump should meet the working pressure of the process. Usually, the limit pressure of the pump is about an order of magnitude lower than the technological requirement. Each pump has a certain range of working pressure, so the working point of the pump should be selected in this range, and it can not be allowed to work at external pressure for working pressure. Under the working pressure, the vacuum pump should be able to drain the total amount of gas generated in the process of vacuum equipment. If the process is not allowed, no vibration pump or vibration control measures should be adopted.
We must understand the composition of the gas being extracted. The gas contains no condensable steam, whether there is particle dust or whether it is corrosive or not. When selecting a vacuum pump, it is necessary to know the composition of the gas and select the corresponding pump for the selected gas. If the gas contains steam, particles and corrosive gases, auxiliary devices such as condensers and dust remover should be installed on the intake pipe of the pump. When choosing an oil sealed vacuum pump, we should consider the environmental impact of the oil vapor discharged from the vacuum pump. If the environment is not allowed to be contaminated, an oil free vacuum pump should be selected or the oil vapor discharged to the outside. When a vacuum pump is unable to meet the requirements of pumping and vacuum, several pumps are needed to complement each other to meet the technological requirements.
The above are the points for attention when choosing dry vacuum pumps. We can refer to them and purchase them strictly according to the regulations in the future purchase process. We can avoid unnecessary trouble. If you do not understand, you can call for advice. We will give you reasonable suggestions according to your actual requirements.
