Strengthening the stable operation and improving reliability of circular arc gear oil pumps through research

Strengthen the stable operation and improvement of gear oil pump

In the practical operation of gear oil pump mechanical seal technology, attention should be paid to its stability. However, some units and technical personnel lack the operation process and details, which makes it difficult to smoothly apply the mechanical seal technology for pumps. This mainly includes: the lack of stable operation in the flushing system, and the lack of stable operation during maintenance and assembly. The instability of this operation will form a prerequisite for the hidden dangers of problems under overheating conditions. Therefore, the lack of stable operation in practical applications also has a significant impact on the performance of mechanical seals used in pumps.

Stable operation is not a single and one-sided simple process, but a rational system layout. Based on the essence of the study on the operability of gear oil pump mechanical seals, "operability" is closely related to "stable operation", as follows:

① The sexual operation of the flushing system should be set up, and the flushing frequency, flushing intensity, etc. should be reasonably adjusted to ensure the normal operation of the flushing system;

② Strengthening the precision of maintenance and assembly is mainly aimed at the actual needs of pump mechanical seals, that is, assembly precision. Only with assembly precision can it be conducive to the continuity of pump mechanical seal operation;

③ Monitoring the operation status of the mechanical seal of the gear oil pump throughout the process can start from the above-mentioned issues, that is, "investigating each factor one by one". If problems occur, they should be rectified in a timely manner, and relevant auxiliary systems and equipment should be used reasonably to lay an important foundation for the continuous operation of the mechanical seal for the pump.

[2] Research on improving the operational performance of circular arc gear oil pump

Chemical circular arc gear oil pumps typically transport high-temperature, flammable oil and gas as the medium, and operate under harsh conditions. They are equipment prone to malfunctions and play an important role in the production process. The number of circular arc gear oil pumps in the petrochemical industry of refineries can reach thousands, and the cause of each failure is different. The operation of high-temperature circular arc gear oil pumps is related to the production of enterprises and has a direct impact on their economic benefits. To avoid accidents and production, monitoring and managing the status of high-temperature circular arc gear oil pumps is an important task in the management of chemical circular arc gear oil pump equipment. At present, most enterprises are still in the stage of offline monitoring, manual inspection, and regular and planned maintenance. Provide an online monitoring system for the status of circular arc gear oil pump group for these small key rotating equipment, which can collect vibration and temperature information of the pump at regular intervals, automatically perform statistical analysis on the operation status, display the current operation status, historical operation data, and alarm push and analysis of the circular arc gear oil pump on mobile terminals and PC terminals, realize online monitoring and management of the status of the circular arc gear oil pump group, facilitate timely detection and handling of faults, and promote enterprise production.

The malfunction of chemical arc gear oil pump equipment is likely to cause serious accidents, so the production process of chemical enterprises needs to monitor the operation of the equipment in real time. Applying modern management techniques to equipment management can effectively achieve real-time monitoring of equipment and timely upload the detected data to relevant departments, which helps to formulate preventive maintenance measures and meet the development needs of equipment management work.
