Compressor installation and safety
| One. Installation Install selected sites of the most neglected by the staff. Often just to find a position after the compressor purchase, immediately after the pipe, there is no advance planning. Little do they know so hasty results, but the reason for future compressor failure and poor maintenance difficulties and the formation of air quality. So choosing a good place to install the proper use of compressed air system but a prerequisite. 1. Wide well-lit place to be, in order to facilitate the operation and maintenance. 2. It should be low relative humidity, less dust, clean air and good ventilation. 3. The ambient temperature must be below 40 ℃, because the higher the ambient temperature, the less the amount of output air compressors. 4. If the factory environment is poor, dusty, pre-filtering equipment should be installed. 5. Reserved access, qualified crane may be installed to facilitate maintenance. 6. Reserve maintenance space shall be at least 70 cm above the distance between the compressor and the wall. 7. Compressor spatial distance from the top of at least one meter or more. II. Piping, foundation and cooling system Notes 1. The air line tubing Notes (1) main line pipe, the pipe must have an inclination of 1 ° ~ 2 °, to facilitate the condensate discharge pipe. Pressure (2) pipe passage of the drop shall not exceed 5% of the set pressure of the compressor, it is preferable to use a larger diameter of piping. (3) Extension pipe must be connected to the main line from the top, to avoid condensation of water downstream pipeline to gas equipment, compressor air outlet tube should ideally be a one-way valve. (4) several compressors installed in series, it should be installed in the main line valve terminal or automatic drain valve, to facilitate condensate discharge. (5) Do not arbitrarily narrow main line shall be used if necessary to reduce or enlarge the line when the tapered tube, otherwise the joints will be mixed to happen, resulting in a large pressure loss, but also affect the life of the pipeline. (6) After the compressor cylinders and dryer if other purification buffer facilities, ideal for piping should be before the compressor + tank + filter + dryer + filter + fine filter. So part of the condensed water tank can filter, while the gas tank also reduced functionality exhaust gas temperature of. A lower temperature and less moisture, the air and then into the dryer, the dryer can reduce or control the filter load. (7) If the system of a large amount of air and the time is very short, the instantaneous gas consumption vary widely, should install a gas tank as a buffer only (its capacity should be greater than or equal to 20% of the maximum instantaneous gas), so you can reduce the number of compressor Frequent loading or unloading, reducing the number of operations control element to maintaining the operational reliability of the compressor have great benefits. Under normal circumstances, you can choose a capacity of exhaust 20% of the gas tank. (8) 1.5MPa less compressed air system pressure, flow rates within the pipeline that need to be in 15m / sec or less, in order to avoid excessive pressure drop. (9) pipe bends and minimize the use of various types of valves to reduce the pressure loss. (10) The ideal pipe is the main line around the entire plant, so at any position can get double aspect of compressed air. As a branch, the sudden increase in gas consumption, can reduce the pressure drop. And a trunk line in a ring configuration appropriate valves in order to cut maintenance purposes. |
