What are the requirements for refrigeration compressor installation
What are the general requirements for refrigeration compressor installation? The editor will introduce it to you, and hope to help everyone! 1. Collect the original materials and technical documents of the refrigeration device and system design, and be familiar with all the contents. 2. Check the completeness of all the approach equipment, the number of accessories and other details, with all kinds of installation tools, calibration horns and other materials. 3. According to the requirements of the construction drawings, carry out unpacking inventory and appearance inspection of the refrigeration compressor unit (such as packaging, equipment name, specification model, inspection certificate, instruction manual, distribution book and equipment surface, etc.), and make inspection records. 4. For the refrigeration compressor unit leaving the factory, it should be installed within the specified warranty period, and the oil seal and gas seal should be good, no rust, and the inside can not be disassembled and washed. When the anti-rust shelf life is exceeded or there are obvious defects, the unit should be disassembled and cleaned, and refer to the refrigeration unit factory data and technical documents. 5. When installing the refrigeration compressor unit, it should be leveled and adjusted on the base surface of the foundation and base, and those with vibration reduction requirements should be installed according to the design requirements What are the requirements and installation conditions of refrigeration compressor installation Refrigeration compressor installation conditions 1. Choose a wide and well-lit place to facilitate operation and maintenance. 2. The relative humidity of the air should be low, with less dust, clean air and good ventilation. 3. The ambient temperature must be below 40℃. 4. If the factory environment is poor and dusty, pre-filter equipment must be installed. 5. Reserve a passageway, and those who have the conditions can install a crane to facilitate maintenance. 6. Reserve space for maintenance. The distance between the compressor and the wall must be at least 70 cm. 7. The distance between the compressor and the top space is at least one meter. Precautions for refrigeration compressors Precautions for piping, foundation and cooling system: 1. When piping on the main road, the pipeline must have a slope of 1°; ~2°; to facilitate the drainage of condensate in the pipeline. 2. The pressure drop of the piping pipeline should not exceed 5% of the set pressure of the compressor, so it is best to use a larger diameter for piping. 3. The branch pipeline must be connected from the top of the main pipeline to avoid the condensation water in the pipeline from flowing into the air-consuming equipment. The compressor air outlet pipeline should preferably have a one-way valve. 4. Several compressors are installed in series, and a ball valve or automatic drain valve must be installed at the end of the main pipe to facilitate the discharge of condensate. 5. The main pipeline should not be arbitrarily reduced. If you must reduce or enlarge the pipeline, you must use a reducer, otherwise there will be mixed flow at the joint, resulting in large pressure loss and affecting the service life of the pipeline. 6. If there are purification and buffer facilities such as air tank and dryer after the compressor, the ideal piping should be compressor + air 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 temperature of the gas exhaust. The air with lower temperature and less water content will enter the dryer to reduce the load of the dryer or filter. 7. If the air consumption of the system is large and the time is short, the instantaneous air consumption changes greatly, it is advisable to install an air storage tank as a buffer (the capacity should be greater than or equal to 20% of the maximum instantaneous air volume), which can be reduced The frequency of frequent loading or unloading of the compressor unit, reducing the number of control element actions, has a great benefit in maintaining the reliability of the compressor operation. In general, a gas storage tank with a capacity of 20% of the displacement can be selected. 8. For compressed air with a system pressure below 1.5 MPa, the flow velocity in the delivery pipe must be below 15 m/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 pipeline surrounds the entire plant, so that you can get double compressed air at any location. For example, when the gas consumption of a certain branch increases suddenly, the pressure drop can be reduced. And configure appropriate valves on the ring main line to facilitate the maintenance and cut-off.
