Electromagnetic pulse valve selection?

Choose the high-quality brand imported: electromagnetic pulse valve is the heart of dust removal equipment, the total price is about 5% of the total price of pulse jet dust collector; it is the 1% cost of air box pulse dust collector, choose zui high quality The imported pulse valve is only 1-2% higher than the total cost of equipment using domestic valves. Therefore, it is not worthwhile to save the equipment cost on the pulse valve and bear the risk of failure of the entire dust removal system.
Choose a valve manufacturer with a long history: the valve manufacturer must have more than 10 years of production history and successful operation cases, so as to ensure that the pulse solenoid valve product has a perfect quality assurance system, truly achieve 100,000 times of 5 years of inspection. .
Choose a 5-year free warranty period: the number of experimental actions of the pulse valve is not enough to explain the quality of the valve, and the diaphragm must pass the natural aging factor of the age. Therefore, valve suppliers must provide free warranty for diaphragms and solenoids, typically 5 years.
The uniformity of the production quality of the pulse valve is selected: the manufacture of the valve must be a fully automatic production line equipped with a robot and a CNC center to prevent the production quality from being inconsistent due to human processing. In a cleaning system, the entire system is often paralyzed by the leak of one valve.
Select the low-resistance pulse valve: the internal structure of the pulse valve needs to ensure a large amount of blowing gas, a long diaphragm stroke, and the internal structure of the housing is designed to make the valve resistance small according to the fluid mechanics design. Due to the improper design of the valve body, the valve injection volume of some 3" ports can only reach the valve injection volume of the "1~"2 interface. The pulse valve with low resistance and high injection volume can clean the valve. A large area of ​​filter material greatly saves the overall cost of the injection system. Due to the reduction in the number of valves, the operation and maintenance costs of the dust collector are correspondingly reduced.

Pulse valves with high, medium and low pressure ranges are available: the pressure range of the pulse valve must be at least 1 to 8 kg/cm2. In this way, if the resistance of the filter material increases with time during the application process, the air bag pressure can be adjusted to maintain the good running resistance of the dust collector, and the filter material can not be affixed to the bag.
