Safety protection system of 15 hp air compressor industrial

1, motor overload protection

There are two main motors in the air compressor system, one is the main motor driven by the air compressor, the other is the cooling circulation fan motor. Under normal conditions, the operating current of the motor shall not exceed 10% of the rated current (e.g. due to voltage drop, three-phase unbalance, etc.). When the motor running current exceeds the limit set by the power protection device, the over-current protection device will automatically cut off the main power supply and the air compressor will stop. Such as motor internal loss, motor underphase operation, safety valve does not operate, system setting failure, oil separator blockage, etc. If the motor is found to be overloaded in operation, it should immediately contact the manufacturer and send staff to check and find out the reason, otherwise the motor will be burned out. 15HP Air Compressor Industrial

Water-cooled air compressors generally reduce heat transfer efficiency due to scaling and blockage of cooling copper pipes, leading to high temperature tripping. The cause of overloading of the highest common motor in air compressor design: human operation error. Such as self-adjustment of exhaust pressure, improper system adjustment, etc. Mechanical reason. 15HP Air Compressor Industrial

2, exhaust temperature too high protection

The maximum exhaust temperature set by the system is 105-110℃. If it exceeds that, the power supply will be cut off by the system itself. General exhaust temperature is too high for many reasons, but the most common reason is the failure of the oil cooler. If the heat sink fin of the air-cooled oil cooler is blocked by dust, the cold air cannot pass through the cooler freely, then the lubricating oil will gradually rise and lead to high-temperature shutdown. Therefore, every once in a while, the pressure air must be used to remove the dust on the cooling fin. If the plug on the fin can not be blown clean, it is best to use cleaning liquid or solvent cleaning. The ambient temperature is 45℃. If the ambient temperature is higher, the exhaust temperature is higher. Therefore, it is necessary to choose a place with low ambient temperature and good ventilation to place the air compressor. When the intelligent controller detects that the temperature exceeds the set value, it will automatically cut off the power supply. The system cannot be rebooted at this time, unless reset again. In order to avoid overtemperature shutdown as far as possible, the system should be equipped with an early warning device. When the exhaust temperature reaches 100-105℃, the controller will issue a warning signal to remind the operator to pay attention. 15HP Air Compressor Industrial

3, exhaust pressure is too high protection

When the system exhaust pressure exceeds the rated exhaust pressure by more than 0.5bar, the system will automatically cut off the power supply. When the gas consumption is zero (when the oil pressure of the supply brake system is lower than 0.15-0.2Mpa, the pressure switch sends a signal to make the motor stop running and protect the main engine from lack of oil and the valve is closed). When the discharge volume is less than the intake volume, the system pressure will rise rapidly to cause the relief valve to act and deflate. In order to avoid the frequent operation of the safety valve and increase the safety factor of the machine, it is necessary to set this protection. 15HP Air Compressor Industrial

4, lubricating oil pressure is too low protection (user choice)

When the oil pressure of the system is lower than 0.15-0.2Mpa, the pressure switch sends a signal to stop the motor to protect the host from burning out due to lack of oil. 15HP Air Compressor Industrial

5. Alarm device

There are three alarm devices: air filter blocking, oil filter blocking, oil separator blocking are displayed on the LCD panel. When the panel has a fault indication, it means that a filter has been blocked. The user must replace the spare parts in the shortest time, otherwise the performance and safe operation of the air compressor will be affected. 15HP Air Compressor Industrial
