How to promote the application of vacuum system in domestic paper machine? - - - - - -

the key equipment of vacuum system to analyze the influencing factors, how to apply the vacuum system in domestic paper machine in ascension. Vacuum pump system software is one of the auxiliary system software of paper machine, its key function is to assist the paper of dehydration, also both paper amplitude migration, clean clothes, and so on. With the machine, the rapid expansion of scale of operation, the effect of vacuum pump system software increasingly highlighted, but in increasing dehydration high efficiency, save floor, machine equipment project investment and saving vacuum water pump energy consumption of the system software with step expansion, causing the operation cost rise, so choose a suitable vacuum system for paper machine manufacturer is critical.

the properties of the vacuum system:

the equipment after the first time since the start, all the operation process can maintain automatic control. Its work, the various parts of the vacuum system of vacuum degree from beginning to end within the permitted category about ups and downs, the ups and downs category can be adjusted according to the customer to carry out. First starting to not vacuum pump on the second starting to do after delimit vacuum water pump set to do the first and second pause circulatory system work, this equipment when no one is actually operating condition system to carry out the automatic control system, can fully automatic closed when power vacuum system. Additional control cabinet can maintain vacuum water pump motor load and short-circuit fault.

the vacuum system is equipped with the key influencing factors of

1. Net of paper of water

2. Quantitative analysis sheet

3. Slurry water filtrate

4. Slurry type

5. Machine equipped with

6. Sealing water temperature

7. Paper machine speed

8. Fleece moisture content and fleece

9. Vacuum degree and the total number of dehydration components

how to apply the vacuum system in domestic paper machine for? Vacuum pump of high and new science and technology offer professional and technical personnel from the following several aspects to consider:

(1) wet suction box. Out of wet suction box manipulation was within 3%, in order to ensure that all concentrated water to rush pulp, on the basis of speed can be set 3 - per hour Four wet suction box.

2 low vacuum deposit-taking tank. Outside the production according to the ascension of the mesh density to relieve the load tube of dehydration.

(3) high vacuum deposit-taking tank. Several gas slightly larger low vacuum tube equipped with deposit-taking water tank, vacuum 15 ~ 30 kpa is advisable.

(4) composite area high vacuum box. Because for vacuum degree is higher, it is better to separate vacuum pump.

5] coucher vacuum pump. Set a vacuum pump suction fat, vacuum degree is in commonly 50 ~ 60 kpa, suction is commonly 300 mm wide.

[6] vacuum roll. Smoke gas is not suitable for high, degree of vacuum in 40 ~ 60 kpa, can apply a liposuction area, width is 150 ~ 200 mm.

paper machine is the key to to sheet molding in papermaking industry and industrial equipment, although the vacuum system is to assist the dehydration of the paper machine reasonable driving force, but if set too high, it will be the system software electric energy waste, but also will increase damage carpet and dehydration components, thus, described about several aspects of the vacuum system of the equipment to promote content is very important, hope everyone can pay great attention to, this way can guarantee the system software is smooth, reduce energy consumption and generate more profit.
