Generally speaking, the quality of the diaphragm of the pulse valve is very important, which can directly affect the effect of the operation and the service life. The higher quality of the pulse valve diaphragm will reduce the capital money. This kind of high-quality diaphragm needs Very strong flexibility and high sealing performance.
- Select imported high-quality brands: electromagnetic pulse valve is the heart of dust removal equipment, and its total cost is about 5% of the total cost of pulse dust collector; the total cost of selecting high-quality imported pulse valve is only 1-2% higher than selecting domestic pulse valve . Therefore, better diaphragms are more durable.
- The production quality of electromagnetic pulse valve is consistent: the valve manufacturing must adopt a fully automatic production line, equipped with a robot and a numerical control center. The production quality caused by the treatment process is different. In the ash cleaning system, due to valve leakage, the entire system is often paralyzed.
- Selection of low-resistance pulse valve: The internal structure of the shut-off valve pulse valve needs to ensure large jet air volume and long diaphragm stroke, and the shell structure is designed according to fluid mechanics to reduce valve resistance. Due to improper valve body design, some valves with 3quot; ports can only reach valves with ports 1~2. If a submerged pulse valve with low resistance and high injection volume is selected, each valve can clean a larger area of filter material, saving the overall cost of the injection system.
- Choose electromagnetic pulse valves that can be used for high, medium, and low pressure limiting: the pressure limit of the underwater pulse valve of the gate valve is at least 1-8kgcm~2. How to assume that during use, when the resistance of the filter material increases with time, adjust the air bag pressure to ensure that the filter material does not stick to the bag, so as to achieve the superior operating resistance of the dust collector.
