The pneumatic system knowledge of portable batching plant
The pneumatic system is one of the important components of the portable batching plant production line, its function is to ensure the accuracy of the addition of various aggregates, cement and other raw materials in the batching plant. The pneumatic system of portable concrete batching plant mainly includes six parts, including air compressor, air source treatment, air distribution package, cylinder, two-position five-way solenoid valve and two-position three-way solenoid valve, in which the air compressor is the main part of the source device and plays an important role in the pneumatic system.
The working principle of the pneumatic system is as follows: the high-pressure gas from the air compressor is processed by the gas storage tank and then processed by the gas source triple piece, and enters the electromagnetic valve. When the electromagnetic valve receives the control signal, the corresponding circuit is connected. The compressed air enters the driving original (cylinder, vibrator, and auxiliary air cushion) to complete the corresponding action (the door switch, the vibration start and stop, the arching start and stop).
The pneumatic system of the portable concrete batching plant plays an important role in the work of the concrete mixing plant. There are also many things to be aware of during the use process. The details are as follows:
First, the precautions before use: the air compressor should be placed horizontally, fixed, well ventilated, can not withstand wind and rain, can not be exposed to the sun. When replacing the belt, the entire group should be replaced to maintain the same tension.
Second, the operation of the precautions: the operator should always observe the working pressure of the air compressor, not allowed to exceed the rated value. Check for oil leakage, air leakage, and abnormal noise. If abnormal conditions are found, stop operation and maintain it immediately.
Third, the maintenance of air compressor: First, the timely discharge of condensate from the portable batching plant. After shutdown, open the drain valve under the gas storage tank and let off the condensate. The oil should be replaced regularly, generally, according to the operation time of the air compressor, the new oil is replaced every 1000h or 4 months, the air filter element is cleaned regularly.
