In recent years, according to the requirements of users, the equipment manufacturers have changed the classification of industrial dust vacuum to open the form, so that the bag repair and maintenance, can not enter the bag room operation. Pulse control instrument using pressure difference method. Improve the diaphragm service life - At present, the domestic factories and mines in the use of classification of industrial dust vacuum generally reflect the pulse valve diaphragm service life is short, spare parts in short supply. Through the dust collector top movable cover plate to work, the working conditions of the maintenance personnel. Using the upper cover, maintenance condition - classification of industrial dust vacuum for external filter continuous cleaning. The filter bag room is located on the side of the dust bearing air flow. When the side door is used, the dust collector cannot enter the filter bag room during operation, and the working conditions of the maintenance personnel are also bad when the machine is shut down for maintenance. The fatigue strength of the diaphragm in China is only 40 ~ 50 thousand times, and the life of the diaphragm is about 1 month. As a result, the spare parts of the diaphragm have become the burden of maintenance work in the classification of industrial dust vacuum used in various factories and mines. The current domestic production of cloth bag dust removal equipment, dust collector resistance is limited to 120 mm water column range. Analysis of the reason: mainly domestic classification of industrial dust vacuum generally adopt regular periodic blowing, that is, every 30-60 seconds blowing once, each time 0.1 ~ 0.3 seconds. The general fatigue strength of the diaphragm, the index is L 50,000 times, under the condition of continuous operation of the dust collector, the diaphragm life is 2/3 months. The correct selection of filtration speed, dust collector purification rate - filtration speed of industrial dust vacuum is directly related to the dust resistance of dust collector and the concentration of dust at the inlet of flue gas treatment.
classification of industrial dust vacuum maintenance:
1. When starting up, the compressed air should be connected to the gas storage tank, the control power supply should be connected, and the ash discharge device should be started. If there are other equipment in the system, the downstream equipment should be started first.
2. When the cloth bag dust collector is working normally, the dust discharging device can not stop working, otherwise, the dust bucket will soon be filled with dust that spills into the bag room, forcing the classification of industrial dust vacuum to stop working.
3. The oil-water separator in the gas storage tank and air source triplet should blow down once per shift, and the oil-water separator should be cleaned once every 3 to 6 months. The oil mist should check the oil storage situation frequently and refuel in time.
4. If the electromagnetic pulse valve fails, it should be swept away in time. If there are impurities and moisture inside, it should be cleaned up.
5, management personnel should be familiar with the classification of industrial dust vacuum principle, performance, use conditions, and master the adjustment and maintenance methods.
6, the use of timing type cleaning controller, should be determined regularly whether the cleaning period is accurate, otherwise should be adjusted. When using fixed-resistance pulse controller, the working condition of the pressure switch should be checked regularly, and whether the pressure port is blocked and cleaned.
7, reducer, ash delivery device and other mechanical moving parts should be in accordance with the provisions of oil filling and oil change, found abnormal phenomenon should be cleaned in time.
8, shutdown, after the process system stops, should keep classification of industrial dust vacuum and exhaust fan continue to work for a period of time, in order to dust the moisture and dust in the equipment, note that, When the classification of industrial dust vacuum stops working, the classification of industrial dust vacuum is repeatedly cleaned (manual cleaning can be used), and the dust on the dust filter bag is removed. To prevent moisture from burning the bag.
9. When stopping, it is unnecessary to cut off the compressed air source. When the fan is working, the compressed air is provided to the lifting valve cylinder to open the lifting valve.
10. Regularly measure the process parameters of the cloth bag dust collector, such as smoke volume, temperature, concentration, etc. If any abnormality is found, the cause should be found and promptly disposed of.
