The common fault relief valve of the loose pressure valve is installed in the cylinder head of the air compressor. It works in the compressed air environment for a long time, and the compressed air contains certain oil, water and dust, and the working temperature of the air compressor is very high. High, in addition, if the vehicle is stopped for a long time, it is easy to cause corrosion of various parts in the loose pressure valve, the valve stem will become inflexible or even stuck in the valve body, and the spring will lose its elasticity or break, thus showing Various faults. 1) The valve stem is stuck. When the valve stem of the loose pressure valve is stuck at the lower end, the air intake valve of the air compressor is always open, the air compressor is idling, no compressed air is discharged from the exhaust valve, and no compressed air enters the wet Air reservoir. When the valve stem of the loose pressure valve is stuck at the upper end, the intake valve of the air compressor is always closed, and the valve stem can never open the intake valve. No matter how the air pressure regulating valve is adjusted, the compressed air cannot be limited to a certain The pressure range is constantly rising. At this time, the loose pressure valve does not work. The air compressor generates a large amount of compressed air. When the pressure of the compressed air in the wet air reservoir is greater than the pressure set by the safety valve, the compressed air will be safe. The valve is discharged. When the valve stem of the loose pressure valve is stuck in the middle position, the air compressor inlet valve is in a half-open or semi-closed state, causing the air compressor to pump slowly or even not pumping. 2) Spring spring failure or breakage When the spring force of the loose pressure valve is exhausted, it is often necessary to wait until the pressure of the air reservoir drops below 550 to 589 kPa to supply air to the air reservoir. When the spring of the loose pressure valve is broken, the spring force of the spring disappears. The valve stem of the loose pressure valve always opens the intake valve under the action of the air pressure in the return air pipe, so that the cylinder of the air compressor is open to the atmosphere, and the air compressor cannot be pumped. After several times of braking, the pressure in the air reservoir cannot be quickly increased after the pressure is lowered, and the intake valve can be closed when the air pressure in the return air pipe is freely released through the small hole at the bottom of the regulating valve. Maintenance and maintenance of the loose pressure valve When the loose pressure valve has a valve stem stuck, spring elastic failure or breakage, etc., the loose pressure valve should be inspected, disassembled and cleaned in time to check the movement of the valve stem in the valve body. If the valve stem is issued, it should be flexible and free to check the technical condition of the spring, and the problem should be replaced or repaired in time. In the daily use of the vehicle, special attention should be paid to the inspection and maintenance of the loose pressure valve when maintaining the air compressor, so as to ensure that the technical state of the loose pressure valve is intact, so that the air compressor is always in a timely and continuous working state during driving. When the brake system is well sealed, the check valve works normally, and the compressed air consumption is not large, the working time of the air compressor will be shortened, which reduces the working load of the air compressor and prolongs its service life. 90 Degree Flat Top Chain Curve Unit Pallet Transfer System,Curve Belt Conveyor,Pallet Conveyor Belt,90 Degree Curve Belt Vitrans Automation Equipment Co.,Ltd , https://www.vitrans-conveyor.com
