The mixer truck plays a key role in engineering construction. The concrete ratio it transports is more scientific, the mixing is more uniform, and the work efficiency is also very high, which is also the reason why the mixer truck is popular in the market.
There are many parts on the self feeding cement mixer. These parts perform their own duties and work together to complete the operation of the mixer. Each part has its own unique function, such as hydraulic valves. There are many hydraulic valves on the mixer, and different hydraulic valves have different functions. The hydraulic valve of the mixer is used to control the flow direction, flow and pressure of the hydraulic oil, which can successively meet the action requirements of the hydraulic machinery under different operating conditions. It can be roughly divided into three categories:
1. Pressure control valve: the pressure control valve of the mixer is used to control or regulate the hydraulic oil pressure in the hydraulic system, such as safety valve, overflow valve, back pressure valve, etc.
2. Flow control valve: the flow control valve of the mixer can maintain the flow of hydraulic oil at a certain value to regulate the movement speed of the working mechanism, such as throttle valve, travel control valve, etc.
3. Directional control valve: The directional control valve of the mixer can be used to control the direction of hydraulic oil flow. There are two kinds of directional control valve and one-way valve. The directional control valve is divided into slide valve and rotary valve. In hydraulic control machinery, the directional control valve is used more frequently. In order to reduce the installation volume of the directional control valve and facilitate the connection of the oil circuit, several directional control valves and safety valves are often installed together, or the valve body is made into a whole, which is called the multi-channel directional control valve.
There are certain principles for the maintenance of the hydraulic valve of the self feeding cement mixer: the daily maintenance of the concrete mixer shall be done well at ordinary times, such as "spot inspection" and "special inspection" of the components. If problems are found, corresponding measures must be taken to eliminate them, so as to ensure the normal operation of each hydraulic valve and hydraulic pressure system. If the hydraulic valve fails, the cause of the failure must be found first.
If you can't solve the problem yourself, go to the nearest maintenance station for repair, and do not dismantle and repair blindly, otherwise it is likely to cause more serious consequences. More relevant precautions come to our website http://www.sdzkjf.cn Consult.
