Technical level of maintenance and installation for petrochemical circular arc gear oil pumps

2022-12-20 06:04:03

{1} Maintenance of Petrochemical Arc Gear Oil Pump

When equipment maintenance personnel carry out maintenance, the main basis for equipment maintenance is the actual operating time of the arc gear oil 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, the large circular arc gear oil pump equipment is different from the small circular arc gear oil 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 circular gear oil pump 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

{2} Improve the sealing and installation technology level of circular arc gear pumps

Sealing and installation problems refer to the problem of inadequate handling of sealing and installation problems during the mechanical seal installation process of circular arc gear pumps, resulting in a decrease in sealing quality.

. In general, there are the following characteristics when seal installation problems occur: firstly, errors in bearing installation occur, which do not match the form of deviations in mechanical seal installation management; Secondly, the selection of bearing models does not meet the requirements of current mechanical sealing management; The third issue is that during the mechanical sealing process of the pump, the back cap of the impeller is not tightened, which reduces the bearing capacity and hinders the treatment effect of the mechanical sealing technology

Based on the work arrangement requirements of mechanical seal management for pumps, improve the installation technology level of mechanical seals for pumps. For example, training on the quality and skills of mechanical seal personnel can improve the skill level of relevant personnel, reduce the probability of accidents in the installation of pump mechanical seals, and provide guidance for optimizing the quality of pump mechanical installation management. As a pump mechanical seal management personnel, it is necessary to integrate the installation management methods of pump mechanical seals. In the control and optimization of their installation management methods, it can provide guidance for the improvement of pump mechanical installation management work
