Own recent study of air compressors is some knowledge, learn together need it.
How to install the air compressor equipmentThe selected installation site overlooked by most staff. Compressors are often easily find a position after the acquisition, immediately after piping, there is no advance planning. Little do they know the results of such a rash, but the formation of future maintenance problems and the compressor malfunction and poor air quality reasons. So choose a good place to install the proper use of compressed air system but a prerequisite.
1. A good place to be broad daylight, in order to facilitate operation and maintenance;
2. Air relative humidity should be low, less dust, the air clean and well ventilated;
3. Ambient temperature must be below 40 , due to the higher ambient temperature, the compressor output air volume of less;
4. If the factory environment, poor, dusty, pre-filtration equipment to be installed;
5. Reserved for access, qualified crane may be installed to facilitate maintenance;
6. Reserved for maintenance of space between the wall and the compressor should be at least 70 cm above the distance;
7. Compressors distance from the top of the at least one meter or more;
8. For air cooling unit, the proposed installation of the cooling air guide duct derived Outdoor:9. Of water-cooled unit, cooling water supply pressure should be 0.2-0.6MPa, import and export of valves should be installed; if the cooling water may be debri


s, should be retrofitted with filters.
The water quality of cooling water requirements are as follows:
cooling water should be close to neutral PH value of the hydrogen ion concentration should be between 6.5-9.5;
mechanical impurities and suspended organic matter were less than 25 mg / l, oil was less than 5 mg / l;
Temporary hardness is less than or equal to 10o (1o hardness equivalent to 1 liter of water containing 10 mg or 7.19 mg CaO MgO).
Second, piping, and cooling system based on notes
1, the air pipe of the piping notes
Head Road, piping, the piping shall be 1 ~ 2 of tilt, to facilitate the discharge pipe in the condensate.
This tube the pressure drop shall not exceed 5% of set pressure compressor, it is best to use a larger pipe diameters.
feeder pipe must be the top pick a competent way, to avoid the charge of road in the condensation of water downstream to the work of the machine, the compressor air outlet pipe should ideally be one-way valve.
several compressors installed in series, should be installed at the end of the competent way valve or automatic drain valve, to facilitate the condensation discharge.
Do not charge any narrow way, if you have to reduce or enlarge pipe reducers to be used, otherwise there will be mixed in the joints occurs, resulting in large pressure loss, but also affect the life of the pipeline.
After the compressor dryer and so if the buffer tank and purification facilities, the ideal air compressor piping should be a storage tank before the water separator filter dryer filter after the fine filter. This tank can be part of the condensed water filter, while the temperature of the gas tank of compressed air are also reduced functionality. Lower temperatures and less moisture the air and then into the dryer, dryer or filter can reduce the load.
If the system is large and the amount of air time is very short, instantaneous gas consumption large installation of a gas tank as a buffer should be used (its capacity should be greater than or equal to 20% of the maximum instantaneous gas), thus reducing the compression Frequent loading unloading unit number of actions to reduce the number of control components, to maintain the reliability of the compressor is running great benefits. Under normal circumstances, you can choose a capacity of 20% of the gas tank exhaust.
system, compressed air under pressure 1.5MPa, flow within the pipeline shall be 15m/sec the following, in order to avoid excessive pressure drop.
minimize the use of elbow pipe and various valves to reduce pressure loss.
ideal line around the pipe is in charge of the entire plant, so any location can be obtained in both sides of the compressed air. If the sudden increase in gas consumption in a branch, you can reduce the pressure drop. Trunk line in the ring configuration and the appropriate valves in order to cut maintenance purposes.
2, basic
foundation should be based on hard ground aerodromes, the foundation shall plane the whole pre-installation levels, in order to avoid vibrations caused by compressor noise.
If the compressor installed in the upstairs, should take the anti-vibration handle, to prevent transmitted vibration downstairs, or the resonance of the building have their own compressors and security pitfalls.
screw compressor vibration generated by small, so no need to do a fixed foundation. To be placed on the ground but its flat, and not for the soft ground soil. Compressor base of the cushion covered with 5-10mm or shock pad to prevent vibration and noise.
3. Cooling System
When you use air-cooled compressor, consider the ventilation. Compressor may not be placed in the vicinity of high temperature equipment to avoid inhalation of hot air causes the compressor discharge temperature is too high to affect the normal operation of the unit.
When using the conditions compressor installed in a smaller confined space, it should be installed pumping, ventilation equipment for air circulation cycle, pumping, ventilation equipment, compressor cooling capacity must be greater than the amount of exhaust fan, and the exhaust outlet location for the compressor to heat the exhaust exit location.
