Exploring the Ways to Improve the Reliability of Circular Arc Oil Pump Operation and Selection Issues

【1】 1. Develop a management plan for the normal operation of circular arc pumps. In the specific production process, multiple circular arc pump equipment are installed in the normal production of petrochemical units in China. In order to improve the stability of its system operation, it is necessary to develop practical and feasible management systems according to the actual needs of the project, thereby improving the economic benefits of the enterprise. When managing equipment, enterprises should strictly follow the prescribed needs to develop a reasonable plan for the operation and management of circular arc pumps, and develop practical and feasible supporting management facilities. In the implementation phase of the management plan, production quality standards, equipment standards for circular arc pumps, and operating specifications for circular arc pump equipment should be formulated as needed, so that technical personnel can carry out various tasks according to the prescribed requirements

2. Basic operation basic work meets the requirements

Because chemical production is used under specific circumstances, it generally needs to be affected by high temperature and high pressure during normal use. In addition, there are many fault problems with circular arc pumps. Therefore, in the equipment acceptance stage of circular arc pumps, it is necessary to check whether they can operate normally, meet the installation quality standards, and effectively improve the stability of gear pump operation.

3. Acceptance management of chemical arc pumps shall be carried out according to the prescribed standards.

The requirements for chemical arc pump equipment are relatively high, and there is a high level of complexity in installation. The installation of this equipment is a key link in the normal operation of the entire chemical system, and the quality requirements are very high.

. From a specific perspective, the size and position of the foundation of the circular arc pump equipment must meet the requirements of the design scheme, and the position accuracy of the positioning anchor bolts must be accurately determined. In short, the chemical arc pump equipment has a direct impact on the operation of the entire system, and the acceptance process is relatively complex, including many processes and procedures. Generally speaking, the supervision unit should organize various personnel to carry out construction, and it is necessary to inspect and manage each installation process, so that its appearance and size can meet the needs of use

[2] Discussion on Selection of Shaft Seals for Circular Arc Pumps

The selection of shaft seals for circular arc pumps includes three commonly used design schemes, namely packing, double end face mechanical seal, and single end face mechanical seal structure.

. The selection of shaft seal for circular arc pumps is an important part of the sealing performance, which is related to the performance and performance of circular arc pumps

The design schemes for single end mechanical seals and double end mechanical seals have complex production processes and require high costs. Therefore, the prices of these two types of shaft seal products are also high. However, the shaft seal effect of using these two types of shaft seal products is very good, and leakage is rare. They have high performance in the production process of chemical products

The production process of shaft seal products with packing sealing structure is simple, the process flow is not complex, and the cost is very low compared to others. However, the shaft seal effect is not good, and leakage often occurs. It cannot be used for the leakage requirements of chemical products, so it can only be used in some low-cost energy transportation shaft seal processes with low leakage requirements

When selecting mechanical seal structures, it is also necessary to divide them into two types: balanced and unbalanced. The balanced mechanical seal structure can reduce the pressure reaching the sealing end face, so this structure is suitable for environments with high liquid pressure for conveying. The non-equilibrium mechanical seal structure is suitable for environments with lower liquid medium pressure during transportation
