Vacuum pump system solution

When using a pump can not meet the requirements of pumping and vacuum, several pumps need to be combined to complement each other to meet the process requirements. The combined vacuum pump is called vacuum pump system. The vacuum pump system can make the vacuum system obtain better vacuum degree and exhaust volume, and the vacuum pump system with high adaptability can make the working condition application obtain high application efficiency. Therefore, we should choose the vacuum pump system correctly.

The application of vacuum pump system needs to do the corresponding preparations, such as the selection of vacuum pump system, assembly settings, etc.

The vacuum pump system shall be selected and applied according to the medium conditions, environmental requirements and working condition specifications of the application project. When extracting the gas, it is necessary to know the composition of the gas and the composition of the extracted gas. The gas contains no condensable steam, whether there is particle dust, whether there is corrosiveness, etc. Select the appropriate pump for the extracted gas. If the gas contains steam, particles and corrosive gas, auxiliary equipment, such as condenser, dust remover, etc., shall be installed on the air inlet pipeline of vacuum pump unit.

When using the vacuum pump system with oil seal vacuum pump, it is necessary to determine whether the vacuum system has requirements for oil pollution. If the equipment is strictly oil-free, all kinds of oil pumps should be selected, such as: water ring vacuum pump, low temperature pump, etc. In addition, the impact on environmental pollution should be considered. If the environment is not allowed to be polluted, the oil-free vacuum pump should be selected, or the oil vapor should be discharged to the outdoor. If the requirements are not strict, oil pump can be selected, and some anti oil pollution measures, such as adding cold well, oil trap, baffle, etc., can also meet the requirements of clean vacuum.

The vacuum pump system is designed to meet the special needs of high vacuum degree. It is a high efficiency vacuum pump system composed of different types of vacuum pumps in series. Vacuum pump system obtains vacuum by means of mechanical, physical, chemical or physical chemical methods.

Vacuum pump system has a wide range of applications, but in the long-term use of vacuum pump system for vacuum circulation, some factors will inevitably lead to the decline of its vacuum degree.

1. The oil circuit in the pump is blocked or blocked, and there is not a certain amount of oil in the pump cavity. Solution: check whether the oil circuit is smooth, and add the same type of vacuum pump oil.

2. Increase the clearance of the fit. This is a long-term exhaust body containing dust and so on, which causes the gap between the rotor and the stator to increase after wear. Solution: check whether the clearance is too large and replace new parts.

3. When the unit is under low electrical load, the end extraction is a micro negative pressure. At this time, if there is a leakage point in the extraction system or the low-pressure heater connected with it, the vacuum of the unit will be reduced. When the electrical load of the unit increases, positive pressure will gradually form at the end of the extraction steam, which can seal the above leakage point, and the vacuum will gradually increase.

4. If the seal water temperature is too high, increase the cooling water inlet of the heat exchanger or clean the heat exchanger (the heat exchanger is dirty).

5. The temperature rise of the vacuum pump is too high, which makes the vacuum pump oil thin and the tightness poor. Cooling water or electric fan shall be used for cooling. Meanwhile, the fitting clearance of relevant parts shall be checked and repaired or replaced according to the specified accuracy requirements.

The above is the preparation and application basis of EVP water ring vacuum pump manufacturers for you to summarize. For more information, please contact email.
