Analysis of how air compressors can safely survive the high temperature season

High temperature alarm in summer is the most common problem. High temperature will lead to increased oil content in the exhaust, increase the consumption of lubricating oil, increase the load of oil removal in the downstream filter or increase the oil content of the air end, which will affect the wear of parts in severe cases. Shorten the service life of parts.

I. Three easy ways to spend the summer

Let customers' air compressors be fearless in the face of high temperature and high humidity, and easily get rid of the downtime caused by high temperature and high humidity in summer. The three tricks are:

1. Blowing cold air air conditioning method: its purpose is to reduce the temperature of the cooling medium and ensure sufficient cooling air volume. For air-cooled units, the corresponding method is to ensure that the ambient temperature of the air compressor station does not exceed 35 °C. Otherwise, some cooling measures should be taken, such as blowing cold air conditioners or setting the inlet of the air duct in a cool corner to reduce the inlet temperature of the cooling air and ensure sufficient cooling air intake.

2. Frequent bathing method: Pay attention to the maintenance and cleaning of the cooler. The cooling fins of the air-cooled unit need to be cleaned frequently to avoid dirt and blockage. The cooler of the water-cooled unit is fouled. Regularly discharge the sewage in the water tank, clean and descale the Y-type filter in the cooling water pipeline, and add algaecide or fresh water to the circulating cooling tower water. Due to the high temperature in summer, the circulating water itself has a large amount of evaporation, so it is necessary to prevent the air compressor from being shut down at high temperature due to lack of water in the system.

3. Breathe well: maintain the equipment on time and replace the filter element, the purpose is to ensure that the air compressor breathes smoothly and the oil circuit is unblocked. The three filters and one oil of the air compressor must be regularly replaced and maintained, which is one of the essential measures. The purpose of replacing the oil is to ensure that the "blood" of the air compressor lubrication system is clean, smooth and smooth. It is necessary to check whether the oil level is sufficient every day, check whether the temperature control valve is in good condition, and ensure that the air compressor has enough oil before running every day. The normal operation of the temperature control valve is reliable.

II.The cooling measures should keep the following points in mind

1. High temperature will make the cooling effect of the motor worse, and the winding temperature will rise, which may cause the motor to overheat and burn out in severe cases. Strengthen the ventilation in the station room of the air compressor. If the air compressor is not well ventilated, the cabinet door needs to be opened or it needs to be connected to the outside world.

2. When the temperature of the inverter is too high and the cooling is not good, a high temperature alarm will also occur, which will reduce the service life of the electronic components. Therefore, it is necessary to ensure that the ventilation of the inverter cabinet is good, and the radiator of the inverter is not dirty and blocked.

3. Drainage can not be less. The reasons for this are as follows:

A. High humidity will increase the water content in the exhaust and oil-air separator of the unit, and the lubricating oil with water will cause the danger of emulsification and deterioration of the lubricating oil. At the same time, this also increases the water removal load of the downstream equipment refrigerated dryer and suction dryer, resulting in excessively high moisture content in the exhaust air. Therefore, it is necessary to regularly maintain the air compressor steam trap to remove internal rust and other dirt to ensure its normal operation.

B. The air moisture content is high. If the trap effect is not good, the components will rust. Dirty blockage will affect the small passages in the trap. In severe cases, the unit will not be able to load and unload normally, and the pressure rise will cause the safety valve to detonate. Regular maintenance of steam traps and replacement of maintenance parts is an essential measure.

C. Under high temperature and high humidity, the parts of the unit are more likely to rust and the service life is shortened, so the rainproof measures of the air compressor station should be guaranteed.

D. There is a trick to long-term downtime

The danger of failure caused by the long-term shutdown of the air compressor will be more serious. When the machine is shut down for a long time, the air humidity will reduce the insulation of the unit, and the circuit will be short-circuited due to moisture. In addition, the head screw and the cavity are also prone to rust, and in severe cases, there may be a stuck phenomenon. Therefore, the air compressors that have been shut down for a long time should be started regularly to drive away the moisture, and measures should be taken to keep the interior of the unit clean and dry if there is no power supply for a long period of time.

III. summer air compressor safety operation measures

1. The air storage tank is one of the most used equipment in the entire compressed air system. It has a simple structure and can stabilize the pressure of the pipe network system, remove some pollutants, reduce the frequent start and stop of the compressor, and prolong the service life of the compressor and effect. An automatic drainer is installed, the safety valve is checked regularly, the pressure gauge indicates normal, and the pipe and valve for draining oil and water are installed at the lower end of the air storage tank. Strengthen the management and maintenance of equipment, improve the safety awareness of operators, manage the equipment by special personnel, and regularly discharge and clean up waste to reduce the occurrence of accidents.

2. The air compressor is safe to use electricity. The selection of the diameter of the power cord during the installation of the air compressor is also a serious test in the high temperature season in summer. The air circuit breaker matched with the air compressor must be in the disconnected position during the maintenance of the air compressor, and during the maintenance and maintenance, a warning sign shall be attached to indicate that the equipment is under power outage maintenance, and the contact information of the maintenance person shall be marked. Others must not close the switch without reason. During the summer inspection of the air compressor, the special grounding wire device should also be checked to prevent the occurrence of dangerous situations such as leakage. During normal inspection, attention should be paid to the change of the pressure gauge. If the pointer changes, it is forbidden to use it again. During normal inspection, if there is a malfunction or abnormal sound, smell, or vibration, it should be stopped immediately for maintenance, and it can continue to be used after the malfunction is eliminated. When the unit is running, it is forbidden to perform maintenance or repair work on the equipment. No flammable and explosive materials or sundries are allowed to be stacked in the computer room in summer. Non-operating personnel are not allowed to enter the computer room without permission. Entering the computer room for work reasons must obtain the consent of the relevant personnel before entering.

3. Matters needing attention in safe operation and operation

After the air compressor is started, check that the surrounding protective devices are in good condition, and there is no obvious oil leakage and air leakage. During the operation, pay attention to the changes of current, voltage and temperature rise, always pay attention to whether there are abnormal noises in various operating parts, and whether the sensor data such as temperature and pressure of the air compressor have changed significantly from the past. The motor and air compressor of the air compressor have special noises, local temperature rises, pressure soars, lubrication interruption or cooling fan shutdown due to failure, serious oil leakage, and air leakage are all potential safety hazards, and must be shut down for maintenance. Regularly maintain equipment, make maintenance records, and prepare first-hand information for equipment management. Ensuring the safe operation of air compressor equipment is the first task in summer, and summer is also the month where safety accidents are most likely to occur. Good maintenance and normal inspection are the first elements to ensure the safety of air compressor equipment in summer. Operation and management personnel at all levels We must attach great importance to prevent accidents, do a good job in safety production tasks, and be the first responsible person.
