First, the water caused by the impact and failure Moisture is absorbed by the compressor moist air, the formation of the cooling. Moisture makes pneumatic components rusty, affecting the action of pneumatic components. The effects of moisture are as follows: 1. Piping. Resulting in rust inside the pipe; pipe corrosion, resulting in air leakage, container rupture; water retention at the bottom of the pipeline caused by insufficient air flow, pressure loss increases. 2. Components. Pipe rust, accelerate the filter mesh plug, so that the filter can not work; tube rust within the valve, causing poor performance, air leakage; rust bites the components bite, can not be smooth operation; directly affect the components of pneumatic components, Resulting in poor conversion, air leakage and instability; water droplets invade the actuator internal, resulting in poor performance; water droplets into the internal components, so that can not operate smoothly; water droplets flushing lubricants, poor lubrication, valve failure, the implementation of unstable components ; Stagnant water droplets caused by inadequate traffic flow, pressure loss increases; the phenomenon of water hammer damage caused by components. 3. Environment. Discharge water released from the exhaust port, pollute the environment. Faults caused by moisture can be used to deal with failure is the removal of water, that is, the compressor outlet temperature dropped to make the water contained in the water droplets were analyzed and excluded. For this purpose, a cooler and separator should be installed and installed after the compressor, and an air filter should be installed in the compressor population. Horizontal pipe has a certain slope, the drain valve installed at the low end. Install a dryer outlet. Water removal measures can be used as follows. a. Adsorption water removal method: Adsorption of water with a strong adsorption capacity of materials, such as silica gel, aluminum and molecular sieve b, pressure dehumidification: to increase the pressure, so that the volume decreases, the temperature drops, and thus precipitation of water droplets. c. Mechanical water removal: mechanical barrier, cyclone and other water removal. d. Frozen water removal: Cooling equipment to make the air cooled to below the dew point, the water vapor condensation into water precipitation. Second, the oil caused by the impact and failure Compressor oil mist mixed with compressed air, and with the heat sent with the compressed air, compressed air is the cause of oil. The impact of oil is as follows: 1. Seal deformation. Sealing ring shrinkage, air leakage valve failure, the lack of output power of the implementing element; sealing ring bubble swollen, increased friction, the valve can not move or lack of output force of the actuator; ring hardening, friction surface wear, air leakage increased Large; friction increases, the valve and actuator failure. 2. Environment. Industrial raw materials directly contact with the air chemicals place the nature of the chemical changes in raw materials; industrial furnaces and other places in direct contact with the fire caused a fire risk; use of air due to the nozzle of the measuring instruments and plugging failure; require extreme oil environment, due to the valve and actuator Sealing part of the oil leakage caused by environmental pollution, oil removal method is the use of oil filter. For example, use a centrifugal filter to remove oil mist particles, adsorb with activated carbon, or degrease with a porous filter. Third, the dust caused by the impact and fault compressor suction dusty air into the pneumatic device, resulting in friction pneumatic components, damage and increase friction. The effects of dust are as follows: 1. Control element. Control element friction and wear and stuck, malfunction and can not change direction; affect the stability of the regulator. 2. Executive components. Friction and wear the actuator and stuck, the action failure; reduce the output force. 3. Amplifiers and other throttling pieces of pneumatic components. So that the throttle baffle orifice clogged due to oil pollution and failure, dust removal method is installed in the compressor suction air filter, air filter before entering the air filter, the filter on a regular basis to clean or replace.

What is the heating effect of the air heater?
The heating effect of the air heater is not good. Where do you use it? Relatively speaking, the heating effect of the air heater is very good compared with other heating equipment. The air heater is also called industrial air heater, which has a wide range of applications,
Factory workshop: because the workshop space of many large factories is relatively large, it is basically impossible to use ordinary heating methods in such a large space, and it will also cause a lot of waste of infrastructure construction costs and later operation costs. At this time, you need to install industrial air heaters in your workshop. They are specially designed for tall spaces.
Material warehouse: many material warehouses have poor ventilation, and some are directly underground warehouses. They are easy to be wet without sunshine, especially in winter. At this time, it is only necessary to equip an industrial air heater in the material warehouse, which can not only keep warm, but also moisture-proof and dry. The key is to move easily and facilitate the oil mine: for some workers working under the mine, the underground working environment is very bad. Only by improving the working environment can work efficiency be improved, so the heating project is launched, In order to bring greater economic benefits to business owners. At the same time, for some energy mines, it is more related to heating safety, but the industrial heating function is very good and competent for this work
