Promote the development of energy conservation and consumption reduction in petrochemical circular arc gear pumps, as well as the selection of hard materials

【1】

Japan proposed the TPM system in the 1970s to promote the development of energy conservation and consumption reduction for circular arc oil pumps in the petrochemical industry. The so-called TPM system refers to the full staff production and maintenance system. With the development of the times, the TPEM system has also emerged, and the system reform is essentially an upgraded version of TPM, which is the production equipment management system.

. This system emphasizes the production and maintenance of equipment, as well as the participation of all staff. By applying this new type of equipment maintenance system, petrochemical enterprises have made new breakthroughs in equipment management and maintenance work. This is a new type of dynamic management model, and the main purpose of this system is to integrate equipment maintenance into the rigid regulations of enterprise production. For petrochemical enterprises, if they want to extend the service life of the circular arc pump equipment as much as possible and optimize the internal equipment maintenance and management work, if the equipment operators do not pay sufficient attention to this problem in daily use and do not conduct regular maintenance and repair after use, the degree of equipment wear and tear will inevitably be very serious

If a large number of equipment stops running or is damaged, it will seriously affect the normal production and economic benefits of the enterprise. Only by achieving the optimization goal of equipment maintenance can the operational efficiency of equipment be greatly improved, energy consumption of equipment be controlled, and sustainable development be achieved

[2] Selection of Hard Materials for Mechanical Seals of Gear Oil Pumps

The mechanical seal structure of gear oil pumps currently mainly refers to the following types of materials:

(1) Metal materials.

For oil media and transmission fluids with low loads, sealing and resource conservation need to be considered, so they are generally not used as hard sealing materials

(2) Engineering ceramics. When the liquid inside the sealed structure is seawater or medicine, engineering ceramics are usually chosen as hard sealing materials. The probability of load level is in the middle level, and it has very high hardness and properties. It has been widely used in the chemical industry in the past few years, and its practical effect is very good. However, with the rapid development of China's chemical industry, the disadvantages of this material, as the main sealing material, have gradually become apparent: during the operation of the system, it will deform under the continuous action of high temperature, leading to the problem of fluid leakage

(3) Hard alloy. This material is widely used in practice due to its strong corrosion resistance and good toughness. It is also a widely used and effective hard material for sealing surfaces, which is very beneficial for the development of the chemical industry

(4) New ceramic side. This material mainly includes materials such as silicon carbide and silicon nitride, both of which have high hardness properties and strong acid, alkali, and oxide resistance. When used at high temperatures, this material also has very high wear resistance, which can meet the needs of normal production
