What are the big problems caused by air compressor glitch?
Q: What are the consequences of a failure of the minimum pressure valve failure?
Answer: There are three reasons, and listen to me slowly.
1. The oil tank cannot rise after the machine starts, causing the air compressor to fail to load.
2. The oil content of the outlet air increases.
3. The on-site air will be poured back into the machine to cause empty tanks. The oil tank pressure cannot be lowered and the air compressor will be injected after parking. Remove the minimum pressure check valve and replace it with new ones if it fails.
Q: What are the consequences of the broken drive belt?
Reply:
1. The machine cannot be loaded after startup;
2. During operation, the oil sump pressure will drop to 0kg and the output pressure will be stopped. Check the cause of the belt break and install a new belt.
Q: What are the consequences of the failure of the intake valve to close?
Reply:
1. The pressure will continue to rise after the air compressor is empty, causing the safety valve to vent.
2. The oil tank pressure rises when empty.
3. When the vehicle is parked, the cooling oil is poured out from the air inlet. Remove the intake valve and maintain it. If it fails, replace it with a new one.
Q: What is the effect of poor contact at the starter connection point?
Reply:
1. The motor operating current rises and causes the motor to be overloaded.
2. The starter heat causes a malfunction.
3. The fuse is burnt. Remove the starter for maintenance.
Q: What is the reason why air compressors have bad gas emissions during work?

1. The mineral oil used contains polar anti-wear additives, and the polar anti-wear additives are mainly phosphorus/sulfur/chlorine. At high temperatures, the air contains a large amount of oxygen, and the polar anti-wear additive oxidizes to produce malodorous gases. Polar anti-wear additives are generally not recommended for use at high temperatures. Just like ordinary gear oils are used on high-temperature chains, the workshop is full of malodorous gases.
2. Ingredients brought in the air, especially those containing phosphorus/sulfur/chlorine. Look around for chemical gases or chemicals containing dust.
3. The rubber hose may be neoprene. The high-temperature lubricating oil dissolves it, and the chlorine is oxidized at a high temperature to generate a malodorous gas. The possible cause is the use of a diester synthetic compressor oil. The diester is easily decomposed, and at the same time, the corrosiveness is relatively large, and the rubber generally swells (partially swells) especially at a high temperature. Neoprene is generally not recommended for use in high temperature and pressure environments.
4. In order to make green, the substitute oil has added a pigment that is not resistant to high temperatures. Most of the pigments contain elements such as phosphorus/sulfur/chlorine, and the pigments have high oxygen to generate malodorous gases. It is best to test the oil, just like testing the blood, directly reflecting the problem.
Q: What effect does our company have to remove the compressor temperature control valve?
Reply:
1. The temperature control valve of the air compressor plays the role of constant temperature control. If the temperature control valve is missing, it will cause the air compressor to trip at high temperature. 2. The temperature control valve is the component that controls the direction of the lubricating oil. If the action is not in place, the temperature of the unit may be too high or too low.
3. Without the temperature control valve, the temperature of the air compressor oil will increase after the work, the high temperature oil will be recycled to the lubrication system to continue to use, the oil temperature will continue to rise, accelerate the deterioration of the oil, increase the load of the equipment, and reduce the friction loss. Seriously, the life expectancy of the equipment is shortened; the operation of the cooler is increased, the power consumption is increased, the operating cost is increased, and energy is wasted.
