In fact, asphalt mixing plants are not uncommon in our daily life. They are mainly a unit that specializes in the mixing of asphalt. What we really don’t understand is the pneumatic system of the asphalt mixing plant, only the correct maintenance. And the operation, in order to exert its maximum production effect, then what are the faults of the asphalt mixing station in the gas path?
The following three points are common faults in the asphalt mixing station:
First, the phenomenon of asphalt mixing station gas source failure:
In fact, there are many faults in the asphalt mixing station, and the components that appear are not fixed. The internal pressure reducing valve, compressed air processing components, piping and air compressor are all relatively easy. Gas source failures often occur, but the solution is also relatively simple and convenient.
The following is an example of an air compressor. It is often the case that the check valve and the piston ring are damaged, or the air filter is severely blocked, and the whole pressure is rising slowly, etc., but if it is a pipeline If there is a leak in the position of the joint, the hose will leak.
There is also the failure of the pressure reducing valve is also more common, the most common should be the pressure can not be adjusted up, resulting in serious impact on the operation and use of the equipment, due to severe pressure cracking of the spring, or the diaphragm rupture Etc., such phenomena can cause the pressure to not be adjusted.
Second, the failure of the asphalt mixing station in the reversing valve:
The most common one should be that the asphalt mixing station cannot be reversed on the reversing valve, or the entire reversing action is slow, causing serious damage to the sealing ring of the valve plug, as well as the pilot solenoid valve in the intake hole, and the row. Severe blockage occurred on the vent, resulting in the normal reversing of the entire directional valve.
The above-mentioned failures of the reversing valve of the asphalt mixing station must ensure that the oil mister is in a good state under working conditions, and that the lubricating oil is applied properly, and that the normal cleaning of small parts is in place to ensure a good condition. Cleanliness, in the end, is the timely replacement of damaged parts, reducing the incidence of failure.
