Domestic oil pump manufacturing industry competition is fier

At present, the oil pump industry in China is very complicated and the competition is fierce. Most of the oil pump plants pursue technological progress and work hard to improve the quality.

And there are some oil pump factory management is not strict, ignore the quality, and even use jerry-building to reduce costs, such as reducing the thickness of the valve body wall, the selection of substandard materials, and even counterfeiting famous brands.

There are also some famous oil pump factories to expand the scope of joint venture, but the loss of management, oil pump quality decreased significantly, hit their own brand.

These years in the petrochemical transformation and expansion projects, fake oil pump has been repeatedly found, which is very dangerous.

There are many types of pump used to control the flow of air, water, steam, corrosive media, mud, oil products, liquid metals and radioactive media.

With the continuous improvement of the process flow and performance of all kinds of complete sets of equipment, the types of oil pumps are still increasing.

 

The domestic oil pump manufacturing industry is spread all over the country, and the number of general oil pump production enterprises has reached 1,300, which has become one of the countries with the largest oil pump output and market demand in the world.

However, China's oil pump industry is mostly small and medium-sized enterprises, the good and bad are uneven, the annual output value of more than a dozen yuan, even compared with other domestic machinery industry, whether in the device or the level of technology there is a big gap, really have independent research and development of high-end products are very few units.

The specifications and models of oil pump products in China have reached more than 40,000, most of which have been standardized and serialized, and some of which can be produced according to international standards.

The highest service temperature of the oil pump has reached 570℃, the lowest temperature has reached -196℃, and the highest pressure has reached 600MPa.

 

General general oil pump basically meet most of the needs of petrochemical production, but special oil pump such as safety valve, globe valve, check valve and other products, due to the lack of sealing materials, improper sealing material matching, heat treatment process can not meet the requirements, affect the performance and service life of oil pump.

Automatic oil pump such as safety valve, pressure reducing valve, trap, lack of test means, some products are not stable performance.

Butterfly valve, throttle valve and other control valves, due to the lack of test means, there is generally no adjustment characteristic curve and resistance coefficient curve.

The control level of electric actuator is low, the control is not effective, and the accuracy is not high.

 

The technical level of foreign general oil pump is high and the development speed is fast. The main performance is as follows: the oil pump is developing towards the direction of large scale, high parameter, automation and integration, the product series is increasing continuously, the new oil pump products have high quality, reliable sealing and long service life;

It is specialized in oil pump research and has a scientific research and test base, which can carry out tests on thermal performance, dynamic performance, abrasion resistance, earthquake resistance, fire prevention, reliability and other kinds of tests, and can carry out performance tests on products in various aspects.

With the development of petrochemical industry and the requirements of technological progress, the demand for high-parameter general oil pump increases, such as high temperature oil pump service temperature reaches 500 ~ 900℃;

The service temperature of low temperature oil pump reaches -40 ~ -196℃;

The service pressure of the high pressure oil pump reaches 300 ~ 500MPa;

Especially flammable and explosive, strong corrosion, toxic medium oil pump, etc., the oil pump safety, reliability of function and service life and other aspects put forward higher and more strict requirements.
