Rotary vane vacuum pump - the application in papermaking industry

the papermaking industry is one of the basic industrial production in our country, China's total pulp papermaking industry company is big, spread wide and the old paper machine transmission device choose dc motor driving more work roll drive system method, the transmission system can guarantee the CVT, but because the motor carbon brush beings to make maintenance is very inconvenient. Sales in the market at present stage vacuum pump is generally used to metallurgical industry, chemical, food, electronics, surface coating and other manufacturing industries, however, is concerned, the paper use vacuum pump because the application will be great vibration caused by the work of the vacuum pump, damage the ecological environment in the work; And when to carry out the installation, adverse to carry out the installation, lead to trouble in the actual operation, reduces the installation efficiency. Therefore, papermaking industry special vacuum pump. Rotary-vane vacuum pump efficiency is fast, small size, light in weight and low noise, convenient maintenance, ultimate vacuum advantage of institutions of higher learning, the paper use the rules of the vacuum pump, the next network under make up guys in detail of rotary-vane vacuum pump are used in papermaking industry.

with the high speed development tendency of paper industry, paper machine, import substitution and efficient running of the marketing application in paper industry in our country rotary vane vacuum pumps, rotary vane vacuum pump is divided into single-stage rotary vane vacuum pumps and bipolar rotary-vane vacuum pump, which can fully use of the rotary-vane vacuum pump, environmental protection and energy saving effect and enhancing vacuum degree, considering the contemporary large medium and small paper machine facilities, turned into a paper machine system software a selection of vacuum technology.

in order to consider the contemporary facilities in papermaking industry rules, and obtain satisfactory application effect and advantages of environmental protection and energy saving, rotary vane vacuum water pump in the application should pay attention to the following content:

1. According to the energy dissipation characteristics of rotary vane vacuum pump, according to the different rotary-vane vacuum pump, vacuum pick specifications can obtain satisfactory environmental protection and energy saving effect, and can improve degree of vacuum, do big small and medium-sized paper machine supporting facilities.

2。 Used in paper industry of rotary-vane vacuum pump, applications should be in the vacuum suction mouth before adding small amount of water sealing, sealing water can be used without hard dirt back into the water, the exhaust valve gap and the effect of cooling pump body, can promote work characteristics of the vacuum water pump, but fill the sealing water can not be too much, or you will increase the driving force of the vacuum pump cost.

rotary vane vacuum water pump used in paper industry the favorable effect is:

1, the paper use vacuum pump structure simple, operation is convenient, according to the shores of motor, and based on the design scheme of shells yellow is beneficial to reduce the vibration of the motor work if frequency, is beneficial to reduce the noise, further improve the ecological environment in the actual operation staff work, reduce the noise pollution;

2, this paper use vacuum pump according to the limit switch board is beneficial for the vacuum pump to carry out the installation, and according to the limit switch board move is good for different parts of the vacuum pump installation, improve the convenience of practical operation, reduces the installation difficulty coefficient, increase the work efficiency.
