Normal exhaust from air handling systems

1、Four protection valve exhaust when air intake
Due to the P21 air pressure is lower than 4 kilograms of air pressure when the mandatory exhaust port of the four protection valve began to exhaust, this time the exhaust is a normal phenomenon, continue to pump when the P21 air pressure is higher than 5 kilograms, the mandatory exhaust port to stop exhausting.
2, cut off the exhaust port leakage
Cut off (can obviously hear exhaust sound from the exhaust port), the exhaust port has a blowback compressed air outflow, this time the dashboard pressure gauge air pressure will slowly decline (about 0.6 kg), 30 seconds after the exhaust stops, the air pressure gauge is stable, check the air pressure system whether the leakage, at this time began to record the gauge pressure (30 seconds after the cut off), and then observe the air pressure gauge pressure whether it is declining.
3、Winter start cut off pressure is high
As the air handling unit air inlet from the air compressor moisture, water will freeze in the air inlet after parking, cut off the cut off pressure will be higher than the factory set pressure of about 1 - 2 kilograms, power on the heater began to work for about 30 minutes, cut off the pressure to return to normal. This is a normal phenomenon.
4、Vent leakage
The regulator has 2 ventilation ports (as shown below) for the internal pressure relief port, sometimes there is a small air leakage in the work process is normal.

Air Handling Components

The common components of this part are: regulator, air dryer {with regulator function}, four circuit protection valve or air treatment unit.1. Regulator (see Figure 1): X80 ~ 90 years on China's commercial vehicles (using air brake) commonly used regulator to control the compressed air system pressure and unloading of the compressor.

Compressed air management systems for commercial vehicles

In our country and in Europe, more and more trucks and buses are using air as a power source to realize the control of the vehicle's braking, gating and air suspension systems, etc. We usually call the generation, treatment and storage of compressed air in the respective storage cylinders as required an air management system. The system mainly consists of: air compressor, air handling components (regulator or air dryer, protection valve, air handling unit, etc.), storage cylinder.
