subject: Zksg Filter Air Compressor - Filters - Filtration And Separation Industry [print this page] Cement grinding process of production more than the ambient air containing high concentrations of dust. Air compressor used dust filter over the original design for the screen type secondary dust. As the dust collecting area is small, Netease plug wire can only filter the larger dust filter is very poor. Fine dust into the air compressor through the suction pipe, the part of the dust remaining in the body increasing the cylinder wear, suction valve piece, seat, springs and other parts have to be the disintegration of the monthly cleaning, replacement. Resulting material, accessories expensive, failure and more, equipment efficiency is low, an increase of labor intensity.
Recent years, we applied ZKSG type muffler combined air filter (referred to as a new filter) to replace the original filter. The filter is a cyclone, oil bath, oil and dust filters and other functions both as one of the muffler of a new, highly efficient, low-noise air filter, whose role is to reduce the suction port noise, improve the environment to reduce the air compressor air inhalation of dust and impurities contained.
1 new filter structure As shown, air flows through the line for the A? B? C? D ~ E? F. New filter for the cylinder type, cylinder divided into three parts: the outer tube 5, the inner cylinder 4, muffler cap 1. The inner cylinder upper plate 3 for the cyclone (or vane) and filter 2, the lower end tube connected with the outer cylinder with compressor oil.
3 Principles of the intake filter and silencer
3.1 Filtering Theory Air is sucked along the tangent direction outside the tube, and high-speed rotating outer cylinder, air flow under the centrifugal force dust particles to be separated from the impact of people outside the tube wall and falling oil pool. Air passing over the oil surface, the generated wave, air entrained some of rotation, including the cylinder wall oil film forming. Flow of dust particles stuck on the film, again separated by secondary purification. Film along the downward movement of the inner cylinder wall, forming the oil screen, by the time the air in through the oil bath, so that part of the dust particles are separated. Tube rotation, including increased air flow across the board after the cyclone speed rotation, the air entrained oil droplets in the rejection of people as part of tank inflow tube through return pipe end, some within the tube wall along the back, washing cylinder wall oil film, trapping the end of the dust fall tube generating new film; air filter to filter through the small final dust and oil droplets, so as to achieve the purpose of purification. Thus, oil changed regularly, you can guarantee that the filtering effect.
3.2 Noise theory Mouth breathing air compressor noise that is around the noise, mainly generated by mechanical air compressor running noise and air noise. Combined air filter silencer with tangential inlet, while the flow of air through the film, oil bath and filter. Increase the air damping and sub-grid to reduce the noise; air flows through multiple expansion, and in the top of muffler muffler cap were to play a good role.
4 Problems in the use of
We use modular muffler filter, installation, commissioning and using special attention Zuodao the following, in order to ensure the results.
(1) use of air muffler filters should be matching with the corresponding displacement of the compressor. I should have a horn suction tube and meet the requirements of the Covers, otherwise it will increase the resistance and noise.
(2) air filter silencer generally installed outdoors, cylinder mounted vertically, keeping the oil surface level, and reinforced to prevent vibration. We Zengyin fixed bad, run the filter input vibration severe, affecting the filtering effect.
(3) air filter silencer with air compressor lubricant grade oil should be the same, and can be used for air compressor oil down, not allowed to refuel when the machine is running.
(4) oil face value to a static subject gap Ah, when the winter run-time heightening the oil surface may be appropriate to maintain the oil within the tube screen.
(5) air muffler or clean the filter after the initial investment in run-time, must be evenly in the oil filter online shower wash.
(6) air muffler filters generally run 3 000h after the oil change, cleaning, specific time determined the number of visible fouling. Three continuous production environment where high dust levels, it is best to conduct a cleansing operation 3000h. Can not believe that the use of air filter silencer effect, the neglect of inspection and maintenance, will result in filter plugging, affecting the filtering effect.
5 Application (1) low noise. Determined by the environmental protection departments to use modular air muffler filters, suction port noise is 80.6dB (A), lower than the national "Industry Enterprise noise standard for>, lower unit engine room noise, improving the working environment, conducive to employee health.
(2) Dust effective. Air compressor to run four months of the dissolution of inspection, almost no dust, smoke exhaust, after calibration Dust efficiency of 98%.
(3) elimination of the air waves of vibration to the surrounding environment. As the air compressor running wave manipulation to the surrounding air to vibrate, the human body, buildings have some impact, use of combined air silencer filter allows effective control of air vibration.
6 Conclusion
Sum up, Combined air filter silencer with good performance. The device or do not have to establish a single large compressor station under conditions suitable for stand-alone package, directly on the outside, reduce construction costs and allow the compressor oil air compressor replacement down to use, has good economic and social benefits.
