How to choose a pulse bag filter
The electromagnetic pulse valve is the heart of dust removal equipment, and its total price is about 5% of the total price of the pulse bag filter. It is an air box pulse bag dust collector; The 1% cost of using electromagnetic pulse valves only increases the total cost by 1-2% compared to using domestically produced valves. So saving equipment costs on pulse valves while bearing the risk of the entire dust removal system failure is not worth it. Choose a valve manufacturer with a long history: Valve manufacturers have more than 10 years of production history and successful operation cases, so that pulse electromagnetic pulse valve products have a complete system and can achieve 100000 injection times for 5 years. Choose a 5-year free warranty period: The insufficient number of experimental actions of the pulse valve indicates that the valve is low, and the diaphragm has been tested by natural aging factors over time. So valve suppliers provide a free warranty period for diaphragms and electromagnetic coils, usually 5 years. Action express, with minimal power and lightweight shape. The response time of electromagnetic pulse valves can be as short as a few milliseconds, and even pilot operated solenoid valves can be controlled within tens of milliseconds. Because it forms its own circuit, it responds more quickly than other self-control valves. A well-designed electromagnetic pulse valve coil has low power consumption and is considered an energy-saving product; It can also automatically maintain the valve position by triggering the action, without consuming any electricity during normal operation. The electromagnetic pulse valve has a small shape and size, which saves space and is lightweight and beautiful. The adjustment accuracy is limited, and the electromagnetic pulse valve with limited applicable media usually only has two states: on/off, and the valve core can only be in two positions, which cannot be continuously adjusted. (There are many new ideas that are trying to break through, but they are still in the experimental trial stage) Therefore, the adjustment accuracy is still limited. Electromagnetic pulse valves have a relatively high level of cleanliness for media, and cannot be used with media containing particles. If impurities are present, they must be filtered out first. In addition, viscous media cannot be used together, and the viscosity range of media used for specific products is relatively narrow.

Due to temperature changes, the fan shaft may change, resulting in an unbalanced operation and causing vibration. Moreover, during idle operation. The star shaped unloader has a compact structure and is easy to use; Smooth operation and low noise; Due to the distance between the bearings and the gearbox from the housing, there is significant lubrication for high temperatures. The specifications of the star shaped unloader can be designed and manufactured according to user requirements. This ash discharge valve uses No.00 reducer lubricating grease. Please check and add oil regularly. The star shaped unloader is the main equipment for dust removal, air supply, and other equipment feeding, suitable for powdery and granular materials. How to choose an electromagnetic pulse valve for environmental protection, metallurgy, chemical industry, and grain? Electromagnetic pulse valve is the heart of dust removal equipment, and its total price is about 5% of the total price of pulse jet dust collectors; It is 1% of the cost of the pneumatic pulse dust collector, and the electromagnetic pulse valve used only increases the total cost by 1-2% compared to the equipment using domestic valves. So saving equipment costs on pulse valves while bearing the risk of the entire dust removal system failure is not worth it. Choose a valve manufacturer with a long history: Valve manufacturers have more than 10 years of production history and successful operation cases, so that pulse electromagnetic pulse valve products have a complete system and can achieve 100000 injection times for 5 years. Choose a 5-year free warranty period: The insufficient number of experimental actions of the pulse valve indicates that the valve is low, and the diaphragm has been tested by natural aging factors over time. So valve suppliers provide a free warranty period for diaphragms and electromagnetic coils, usually 5 years. Choosing an electromagnetic pulse valve with actual injection air volume, rather than just the connection diameter size: the interface size of the pulse valve often cannot determine its dust cleaning function. Some designs of electromagnetic pulse valves use small-diameter diaphragms, but only increase the interface. For example: Application 2; The valve diaphragm is installed on 21/2; Inside the valve housing of the interface. This will result in insufficient air injection from the valve, leading to poor dust cleaning system. Choose a low resistance pulse valve: The internal structure of the pulse valve requires a large amount of air injection, a long diaphragm stroke, and a housing structure designed according to fluid mechanics to reduce valve resistance. Due to improper valve body design, some 3 "interface valves can only achieve the same air injection volume as valves with" 1~"2 interfaces. By selecting electromagnetic pulse valves with low resistance and high injection volume, each valve can clean a large area of filter material, saving 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 have also correspondingly decreased. Therefore, pulse valves that can be used in high, medium, and low pressure ranges should be selected: the pressure resistance range of pulse valves should be at least 1-8kg/cm2. In this way, if the resistance of the filter material increases over time during application, the air bag pressure can be adjusted to maintain good operating resistance of the dust collector, and the filter material will not stick to the bag. Widely used in the food and other industrial sectors. Working principle: When the star shaped unloader is working, dust falls by gravity and fills the star shaped blade spaces on the top and sides The blade rotor is driven by an electric motor through a reducer to rotate the shaft, and the impeller rotates to the lower part to unload the dust by its own weight Star shaped unloaders are generally installed at the lower part of the dust collector ash hopper. In order to ensure a tight connection without air leakage, the upper part of the rotary unloader should regularly maintain (store) a high level of dust. Because when the impeller rotates, the side of the impeller that rotates after removing dust is often free of dust, which makes it easy for air to leak in. In order to maintain a high height of the ash column and prevent it from being emptied, it is fortunate that a material level signal device is installed inside the ash hopper and interlocked with the electric motor of the dust discharge valve.
