How to use a vacuum diaphragm pump correctly

How to use a vacuum diaphragm pump correctly?

First of all, the vacuum diaphragm pump is used to pump equipment in various gas environments, as the vacuum degree continues to rise, the steam will be more and more, so it will inevitably be pumped into the diaphragm pump, in order to prevent this situation, the general diaphragm pump manufacturers will be equipped with a small filter dried, so the filter drier should be connected between the diaphragm pump and the system before use. When the filter drier is used for a period of time, and it is found that there is a certain amount of water in it, and the vacuum degree of the vacuum diaphragm pump cannot reach the previous level, replace the filter drier in time, and after removing the muffler, it can be restored to the normal state after 1-2 hours of no-load operation.

Second, the vacuum diaphragm pump relies on the reciprocating movement of the diaphragm to achieve vacuum preparation, therefore, the heat of the diaphragm pump is still relatively large, under normal circumstances, the surface of the vacuum diaphragm pump without heat dissipation measures can reach 75-80 °C, which is easy to burn people, so it is generally recommended that the continuous working time does not exceed 2 hours. In order to overcome this problem, Zhengzhou Bohui Precision Technology Co., Ltd. research and development and production of DP-630 series vacuum diaphragm pump, the use of low-temperature lifting motor, in the pump body outside the design of a beautiful and generous shell, and the configuration of large air volume axial fan, so that the heat to get a good heat dissipation effect, the outer surface temperature of the casing is about 45 °C, and the internal motor temperature is also well reduced to below 68 °C, effectively prolonging the service life of the whole machine. In addition, the DP-630G is equipped with a high-precision LCD vacuum gauge to make the vacuum level clear at a glance.

Third, the vacuum diaphragm pump is mainly used to pump vacuum, if it wants to be used for pressure (positive pressure state) operation, it should generally not be greater than 0.1MPa, otherwise, it is easy to cause damage to the diaphragm.

Fourth, the vacuum diaphragm pump should be placed in a well-ventilated place when working, and try to stay away from the heat source.

The correct use of the vacuum diaphragm pump will effectively improve the service life of the vacuum diaphragm pump and reduce the occurrence of failures.
