How to ensure the maintenance and management of micro water pumps

Release date:2020-07-16 Author: kf Click:

The power of the micro pump depends on the size of the volume power, hydraulic power and echanical power. Strengthening the maintenance and management of the micro pump can increase the volume power, hydraulic power and mechanical power of the pump. After the pump runs for a period of time, the gap between the leakage reducing ring and the inlet of the impeller may increase due to conflict, which increases the water loss, and then reduces the volumetric power.

Regular inspections should be carried out. When the wear gap of the leakage reduction ring is found to be too large, it should be replaced in time, and the gap between the leakage reduction ring and the impeller should be reduced as much as possible under the premise of ensuring operation and design permitting. When water flows through the miniature pump, friction loss and impact loss will occur. For the honeycomb, pitted surface or deformation of the impeller and pump casing due to cavitation or sand abrasion, it should be coated, repaired or replaced in time; most of the pump should be used Time runs in the high-efficiency section to reduce impact loss.

In order to improve the mechanical power, the mechanical loss should be reduced. For the operation management personnel, the following points should be paid attention to in the research and development of the miniature water pump: the installation and repair are strictly in accordance with the technical requirements of the bearing, and the smoothness and cooling target of the bearing should be monitored in accordance with the operating rules. The power loss of the bearing; strictly control the tightness of the packing gland. If the packing pressure is too tight, the conflict force will increase, and the mechanical loss will be large. It may even burn the packing and the packing is too loose. Although the mechanical loss is reduced, The amount of water leakage increases; in addition, the damaged packing should be replaced in time to ensure a good working condition of the packing seal.
