The destructive effect caused by gear oil pump suction is the same as maintenance

{1} The destructive effect caused by the suction of the circular arc gear pump mainly refers to the extraction of air from the sealed pump. The suction phenomenon is common in mechanical seals used in pumps, but improper operation of the suction can cause many problems. The main destructive effect of vacuum on the pump seal is the "phase change", which leads to the formation of seal vibration. Once seal vibration occurs, it will cause the leakage of gas and water inside the pump, thereby affecting the operation of the mechanical seal of the circular arc gear pump

In response to the impact of suction damage on the operational performance of gear pump mechanical seals, the "suction" operation should be standardized and clarified in depth from the suction process, suction method, etc., to avoid pump seal vibration caused by suction operation. The main methods to avoid internal vibration during the pumping process are still "stable operation", "standardized operation", "standard operation", etc. At the same time, it is necessary to learn and introduce suction technology. The application of mechanical seal technology in "pumps" is not a fixed mode, but a method and means of technology and breakthrough. Only through technical exchanges, problem discussions, and learning and citing suction technology can the performance and stability of mechanical seal operation in pumps be improved

{II}, Petrochemical Gear Pump Maintenance

When equipment maintenance personnel perform maintenance, the main basis for equipment maintenance is the actual operating time of the gear pump equipment.

. In general, after the operating time of small-scale pump equipment reaches 240 hours, a primary maintenance operation needs to be carried out. After the accumulated working time reaches 720 hours, a secondary maintenance operation needs to be started. After reaching 1000 hours, maintenance should begin. However, large gear pump equipment is different from small gear pump equipment, with a cumulative operating time of 1000 hours for primary maintenance, 3000 hours for secondary maintenance, and 10000 hours. When maintenance personnel carry out maintenance, they mainly include the following aspects

Firstly, technicians need to inspect the appearance of the equipment for any issues, including all exposed parts and the transmission structure of the equipment. Secondly, technicians need to check the condition of the transmission structure to determine if there is any looseness or corrosion in the structure. If there are loose positions, tools should be used for reinforcement. In addition, the wear of the bearing parts of the transmission structure should be checked. If the wear is too severe, components should be replaced in a timely manner. 3、 Technical personnel need to check the lubrication of the equipment, including various indicators of lubricating oil testing, status detection of oil filters, and other issues. After checking for accuracy, the oil level should be observed. If the oil level is insufficient, it should be replenished in a timely manner. If there are problems with the quality of lubricating oil, it should also be replaced and not used again to prevent leakage and blockage during subsequent operation. 4、 Technicians should carefully inspect the electrical system of the connected equipment. In order to maintain the cleanliness of the motor, they should frequently use cleaning tools to wipe the motor equipment. In addition, it is necessary to check the wiring ports between the motor and the cable for any poor contact. Afterwards, the insulation and grounding devices of the circuit should be inspected
