Fine management of maintenance and installation issues for gear oil pump equipment

Firstly, the refined management of maintenance and repair of circular arc pump equipment.

The management plan for circular arc pump equipment.

. In the process of carrying out maintenance and management of chemical arc pump equipment, in order to achieve targeted and targeted management, it is necessary to first develop a management plan for the arc pump equipment, and incorporate various work contents in the maintenance and repair of the arc pump equipment into the management plan, to achieve unified, specific, and evidence-based maintenance and repair of the arc pump equipment. Management personnel and corresponding staff can carry out maintenance and repair work according to the management plan, ensuring the implementation of the maintenance and repair work of the arc pump equipment

Institutionalized maintenance and repair work. Include the inspection of the transmission parts of the gear pump equipment, cleaning of components, and recording of the operating time of the circular arc pump equipment in the maintenance and repair work system of the circular arc pump equipment. Use the system to standardize the staff, thus achieving the standardization and institutionalization of the maintenance and repair work of the circular arc pump equipment

Clearly define responsibilities. The management personnel of the circular arc pump equipment are responsible for the maintenance and repair of the entire circular arc pump equipment, and once a problem occurs, the chemical enterprise directly seeks the responsible person's problem, which can promote the sense of responsibility of the maintenance personnel, refine the daily management and maintenance of the circular arc pump equipment by the responsible management personnel. At the same time, in order to ensure the normal operation of the equipment, the responsible management personnel will inevitably strictly require the on duty staff, so as to achieve timely detection and resolution of fault problems

Performance rewards and dynamic maintenance. The main purpose of implementing performance rewards in chemical enterprises is to motivate the responsible persons and staff to have a responsible and enthusiastic attitude towards the maintenance and repair of circular arc pump equipment. In addition, the dynamic maintenance mode throughout the entire process is mainly to achieve mastery of the operation status and fault situation of circular arc pump equipment. The main purpose of implementation is to reduce energy consumption of circular arc pump equipment, reduce the probability of hidden dangers and operational problems of circular arc pump equipment

Secondly, the installation problem of mechanical seals for circular arc gear oil pumps

1. The greater the spring compression, the better the sealing effect.

Excessive spring compression can cause sharp wear or instantaneous burning of the friction pair; It will also cause the spring to lose the ability to adjust the end face of the moving ring, leading to the failure of the sealing of the circular gear oil pump

2. The tighter the sealing ring of the moving ring, the better

Tight sealing ring of the moving ring is harmful and not beneficial. One is to intensify the wear between the sealing ring and the shaft sleeve, leading to premature leakage; Secondly, it increases the resistance to axial adjustment and movement of the moving ring, making it difficult to make timely adjustments when the working conditions change frequently; Thirdly, the spring is prone to damage due to excessive fatigue; The fourth is to deform the sealing ring of the moving ring, which affects the sealing effect

3. The tighter the static ring seal, the better

The static ring seal is basically in a static state, and the sealing effect is better when it is relatively tight, but being too tight is also harmful. One is that the static ring seal is excessively deformed, which affects the sealing effect; The second is that the material of the static ring is mostly graphite, which is generally brittle and can easily cause fragmentation under excessive stress; The third difficulty is installation and disassembly, which can easily damage the static ring

4. The tighter the impeller lock nut, the better

In mechanical seal leakage, leakage between the shaft sleeve and the shaft (inter shaft leakage) is quite common

It is generally believed that inter shaft leakage is caused by the impeller lock nut not being tightened. In fact, there are many factors that can lead to inter shaft leakage, such as the failure of the inter shaft sealing gasket, deviation, impurities, significant positional errors at the fit between the shaft and the shaft sleeve, damage to the contact surface, excessive clearance between various components on the shaft, and excessive thread length at the shaft head, all of which can cause inter shaft leakage. Excessive locking of the lock nut will only lead to premature failure of the shaft gasket. On the contrary, moderately locking the lock nut will maintain a certain degree of compression elasticity of the shaft gasket. During operation, the lock nut will automatically lock in a timely manner, ensuring that the shaft gasket is always in a good sealing state

5. Disassembling and repairing is always better than not disassembling

Once the mechanical seal of the arc-shaped gear oil pump leaks, it is urgent to disassemble and repair it. In fact, sometimes the seal is not damaged, and only adjusting the working condition or adjusting the seal appropriately can leak. This not only avoids waste but also verifies one's fault diagnosis ability, accumulates maintenance experience, and improves maintenance quality
