Compressor installation conditions- YUYAO NINGQI ELECTRIC APPLIANCE CO.,LTD.

The selection of the installation site is most overlooked by the staff. Often after the compressor is purchased, you can find a location at random and use it immediately after piping. There is no prior planning at all. Little do they know that such a sloppy result will cause future compressor failures and maintenance difficulties and poor compressed air quality. Therefore, choosing a good installation place is a prerequisite for the correct use of the air compressor system [12]. 1. A wide and well-lit place is required to facilitate operation and maintenance. 2. The relative humidity of the air should be low, less dust, clean and well ventilated. 3. The ambient temperature must be lower than 40℃, because the higher the ambient temperature, the smaller the output air volume of the compressor. 4. If the factory environment is poor and there is a lot of dust, pre-filter equipment must be installed. 5. Reserve access roads, and those who meet the conditions can install cranes to facilitate maintenance. 6. Reserve space for maintenance, and there must be a distance of at least 70 cm between the compressor and the wall. 7. The compressor should be at least one meter away from the headspace.

　　 Precautions for piping, foundation and cooling system, and air pipe piping [12]: 1. When piping the main pipe, the pipe must have an inclination of 1°~2° to facilitate the drainage of condensate in the pipe. 2. The pressure drop of the piping should not exceed 5% of the set pressure of the compressor, so it is better to choose a larger pipe diameter when piping. 3. The branch pipeline must be connected from the top of the main pipeline to prevent the condensed water in the pipeline from flowing into the air-consuming equipment. The compressor air outlet pipeline should preferably have a one-way valve. 4. When several compressors are installed in series, a ball valve or automatic drain valve must be installed at the end of the main pipe to facilitate the discharge of condensate. 5. Do not shrink the main pipeline arbitrarily. If you must reduce or enlarge the pipeline, you must use a reducer, otherwise there will be mixed flow at the joint, resulting in a large pressure loss and also affecting the service life of the pipeline. 6. If there are purification buffer facilities such as air storage tank and dryer after the compressor, the ideal piping should be compressor + air storage tank + front filter + dryer + rear filter + fine filter. In this way, the gas storage tank can filter out part of the condensed water, and the gas storage tank also has the function of reducing the gas exhaust temperature. The air with lower temperature and less water content enters the dryer again, which can reduce the load on the dryer or filter.

7. If the air consumption of the system is very large and the time is short, and the instantaneous air consumption changes greatly, an air storage tank should be installed as a buffer (its capacity should be greater than or equal to 20% of the maximum instantaneous air volume), which can reduce The frequency of frequent loading or unloading of the compressor unit reduces the number of actions of the control elements, which is of great benefit to maintaining the reliability of the compressor. Under normal circumstances, a gas storage tank with a capacity of 20% of the displacement can be selected. 8. For compressed air with system pressure below 1.5MPa, the flow velocity in the delivery pipe must be below 15m/sec to avoid excessive pressure drop. 9. Minimize the use of elbows and various valves in the pipeline to reduce pressure loss. 10. The ideal piping is that the main line surrounds the entire plant, so that compressed air in both directions can be obtained at any position. For example, when the gas consumption of a branch line suddenly increases, the pressure drop can be reduced. In addition, appropriate valves are arranged on the ring-shaped trunk line to facilitate maintenance and cut-off.

　　Installation foundation 1. The foundation should be built on a hard floor, and the foundation plane must be leveled before installation to avoid the vibration of the compressor and cause noise. 2. If the compressor is installed upstairs, anti-vibration treatment must be done to prevent vibration from being transmitted downstairs or causing resonance, which poses a safety hazard to the compressor and the building itself. 3. The vibration produced by the screw compressor is very small, so there is no need to make a fixed foundation. But the ground on which it is placed must be flat, and the underground cannot be soft soil. The bottom of the compressor should preferably be covered with soft pads or shock-proof pads to prevent vibration and noise.
