When purchasing vacuum equipment, we should not only pay attention to the quality and performance of the equipment, but also pay attention to the installation of the equipment in the actual application process. Correct installation can not only improve the working efficiency of the water ring vacuum unit, but also improve its service life.
1. When the water ring vacuum unit is installed within the anti rust guarantee period, it is not necessary to dismantle and wash it. In case of any abnormality or beyond the anti rust guarantee period, it shall be disassembled and cleaned, and the following requirements shall be met: the disassembly sequence of parts and components shall comply with the provisions of the equipment technical documents; the parts and components shall be free of rust, and a thin layer of lubricating oil shall be applied to the mating surface after the cleaning is qualified; the gaskets at both ends of the impeller shall be changed in strict accordance with the thickness and quantity specified in the equipment technical documents, so as to ensure the water ring Working efficiency of vacuum pump.
2. The leveling and alignment of the water ring vacuum unit should be carried out according to the regulations, and should not be satisfied with the situation.
3. Before commissioning, the following requirements shall be met: the turning gear shall be flexible and free of blocking; the vacuum regulating valve shall be adjusted to the appropriate opening; the cooling water pipe at the filling box of the water ring vacuum pump shall be unblocked; the pump body shall be filled with clean water, and the turning gear shall be cleaned before starting.
4. The test run shall meet the following requirements: the pump shall be operated at the specified speed and within the working range, and the continuous test run shall not be less than 30min; the water supply of the pump shall be normal, and the water temperature and water supply pressure shall comply with the provisions of the technical documents of the equipment; the temperature rise of the bearing shall not be higher than 30 ℃, and the temperature shall not be higher than 75 ℃; all connecting parts shall be tight without leakage; there shall be no leakage during operation Abnormal sound and vibration; after the commissioning, the water in the pump should be drained, and then the pump should be washed with clean water. In order to avoid bad appearance.
5.
