Filter snap ring

Purpose: Oil mist filter fixing sleeve, also known as filter holder, snap ring, buckle, snap ring, etc. Suitable for vacuum pumps such as VC50, VC75, VC100, VC150, VC202, VC303, etc.

The vacuum pump has the characteristics of simple structure, easy operation and convenient maintenance, so it has been widely used in all walks of life. Especially because of its characteristic of isothermal compression, it is easy to suck and compress flammable and explosive gas. The following Shanghai Sueneng Pump Valve briefly summarizes some development trends of vacuum pumps in various application fields.

1. Large-scale

Because of the development of coal, chemical, pharmaceutical, and paper industries, the requirements for vacuum pumps are becoming more and more large-scale. According to incomplete statistics, vacuum products nationwide are mainly used in:
(1) Coal industry
Because the country has strengthened the safety requirements for coal mines, the use of vacuum pumps, especially large-scale water-ring vacuum pumps, to extract gas has become a safety requirement required by the coal industry. Following the country’s further strengthening of safety work, large-scale and extra-large water-ring vacuum pumps Vacuum pumps will be more and more widely used in coal mine systems.
(2) Chemical industry

①Chlor-alkali industry
In recent years, my country has launched many large-scale infrastructure and technological transformation projects, most of which require a large amount of polyvinyl chloride materials, especially the prosperity of real estate, which has further promoted the development of the polyvinyl chloride industry. The development of chlor-alkali enterprises requires supporting water ring vacuum pumps and water ring compressors to extract and compress acetylene and hydrogen.

②Fertilizer industry
The chemical fertilizer industry, especially the production of phosphate fertilizers, is also an industry that is mainly supported in my country's economic macro-control. Because the new projects and the technical transformation of old enterprises are above the level and the scale is mainly, large and super large water ring vacuum pumps have been used. .

③Paper industry
At the end of the last century and the beginning of this century, my country invested a lot in the papermaking industry, and paper mills everywhere rushed to upgrade the level and scale, which greatly stimulated the development and production of water ring vacuum pumps.

④Pharmaceutical industry
Vacuum concentration dehydration, drying, and distillation are the main technological processes of pharmaceutical companies, and the technological transformation of pharmaceutical companies is also at a higher level and scale, which is more significant in some large pharmaceutical companies. In addition to the above industries, the vacuum systems of the food and beer companies in the light industry, as well as the metallurgy, power generation, petrochemical, and building materials industries, are all developing to large-scale.

2. Complete set
In the past two years, in the equipment bidding for technological transformation projects in the chemical and pharmaceutical industries, complete sets of equipment accounted for an increasing proportion. Generally, separators, coolers (heat exchangers), replenishment pumps, valves, instruments, pipe fittings, and The control device forms a closed cycle, and is required to be connected to the company's OCS system to perform online control of liquid level, pressure, and air power. The requirements for this kind of integrated electromechanical equipment are becoming more and more common in many industries.
