Screw air compressor water cooling transformation and air compressor maintenance
ZEGA screw air compressors have a wide range of applications in many fields, and they are equipped with built-in cooling systems, which are simple to install, high in efficiency and reliable. However, in practical applications, screw air compressors equipped with air cooling systems often have the problem of high oil temperature, which seriously affects the work efficiency of the equipment. In this regard, the equipment can be water-cooled to do a good job in the maintenance of the air compressor to ensure its safe and reliable operation.
ZEGA screw air compressors are widely used in many fields, and they are equipped with built-in cooling systems, simple installation, high working efficiency and strong reliability. However, in practical applications, screw air compressors equipped with air cooling systems often have the problem of high oil temperature, which seriously affects the work efficiency of the equipment. In this regard, the equipment can be water-cooled to do a good job in the maintenance of the air compressor to ensure its safe and reliable operation.
Second, the basic principle of water cooling transformation water cooling system, is to use the basic law of heat transfer, the use of cold water to absorb the heat emitted during the operation of the equipment, in the air compressor equipment, water cooling transformation is mainly to the cooling tower, equipment and heat exchanger to build an internal circulation system, when the circulating water loss needs to be replenished in time. During the operation of the air compressor, the internal high-temperature lubricating oil and high-pressure compressed gas will enter the heat exchanger, and the cooling water inside the shell heat exchange, after the temperature drops to a certain extent, the lubricating oil will return to the host to continue to participate in the circulation, the compressed air will be discharged from the air outlet, the cooling water takes away the heat, will enter the cooling tower, after cooling through the water pump pressurization, and enter the system circulation again. In this process, the cooling water can be continuously fed into the heat exchanger, so that the cooling can be carried out at any time, and the cooling effect is significantly enhanced compared to the air cooling system.
The actual operation process of water cooling transformation is as follows: First, the pool is set, select the appropriate position, excavate a pool of about 300mm on the ground, the size is determined according to the actual situation, after the bottom of the pit is compacted, a layer of pebbles is laid, and then the bottom is reinforced concrete to ensure that the sealing effect is good. The main body of the pool adopts a brick-concrete structure, the peripheral size is set to 1780×1780×1490mm, the wall thickness is 130mm, and the overall capacity of the pool is 2m3. From the bottom of the pool upwards, add two No. 10 steel bars every 500mm, and evenly apply waterproof paint on the inside of the wall to improve the waterproof sealing performance; The second is the foundation of the water pump, in order to ensure that the pump can be stable during operation and avoid the negative impact that vibration may cause, the channel steel is used to make the pump base, the size is 100×50mm; The third is the heat exchanger foundation, and stainless steel square tubes are selected to make a special base to ensure the stability and reliability of the foundation.
The fourth is the installation of the cooler, which can be installed in the appropriate position on the roof of the air compressor room, which can not only improve the actual effect of water cooling, but also effectively reduce the chance of impurities entering the water cooling system and avoid blockage problems; Fifth, pipeline connection, it is necessary to connect the water pump, heat exchanger and water pool together, connect the heat exchanger, air compressor oil circuit and gas pipeline together to build a perfect water cooling system. After the transformation, the overall operation effect of the air compressor is good, the oil temperature of the operating state is detected, and it is found that it has dropped from the original 110 °C to 80 °C, no longer trigger the high temperature alarm, and there is no longer a high temperature shutdown problem, at the same time, after the air cooling system is replaced by the water cooling system, the operating noise of the air compressor is significantly reduced, and the vibration problem has been solved.
Third, after the system maintenance water cooling transformation, it is also necessary to regularly maintain the air compressor to ensure its stable and reliable operation. The maintenance of the water cooling system includes daily maintenance and regular maintenance, daily maintenance, need to do a good job of recording the operating parameters of the unit every day, after the unit running time of more than 24h, need to clean the refrigeration and cooling water filter, combined with the pressure gauge on the control cabinet, to ensure that the pressure of the unit evaporator and condenser is normal, clarify the change of water temperature, once the abnormality needs to be dealt with in time. For any shutdown fault, it should be paid enough attention, analyze the cause of the fault, and deal with the fault in time.
Regular maintenance can be divided into weekly, monthly, or semi-annually to ensure the normal and stable operation of the equipment. A monthly maintenance frequency is used to fully inspect the cooling tower, clean the water pan and replace the circulating water. In the normal use process, the sewage valve should be opened regularly according to the specific situation to ensure that the pipeline is unblocked.
Fourth, the conclusion In summary, Chigo screw air compressor in the process of operation, may not timely heat dissipation resulting in high temperature shutdown problem, in most cases is due to the poor heat dissipation performance of the air cooling system, in this regard, in the case of conditions permitting, the air compressor can be water-cooled transformation to improve the heat dissipation effect. After practical testing, the efficiency of the air compressor after the water-cooling transformation has been greatly improved, and the stability and reliability of operation have been effectively guaranteed, which can provide some reference for the transformation of similar equipment.
