Composition In Hydraulic System Of Self Loading Concrete Mixer Truck
The hydraulic system of self loading concrete mixer truck is the key power transmission and control part, mainly composed of oil tank, oil pump, control valve, actuator components (such as motor, oil cylinder), and hydraulic pipeline. The oil tank is responsible for storing hydraulic oil, while the oil pump is responsible for extracting and pressurizing the hydraulic oil from the tank to deliver it to various actuator components. The control valve plays a role in regulating the flow direction, pressure, and flow rate of hydraulic oil, ensuring that each actuator can work according to the predetermined action requirements. The hydraulic motor and hydraulic cylinder are connected to an actuator, which converts hydraulic energy into mechanical energy and ultimately drives each actuator to move.
Hydraulic Oil Tank
This is the “heart” of the hydraulic system, used to store hydraulic oil. The oil tank not only ensures sufficient hydraulic oil supply to the system, but also plays a role in heat dissipation and impurity precipitation. The design and material selection of the fuel tank are crucial for ensuring the cleanliness of hydraulic oil and the stable operation of the system.
Hydraulic Pump
Hydraulic pump is the power source of the entire hydraulic system, which converts mechanical energy into hydraulic energy and provides the required power for the entire hydraulic system. The performance of hydraulic pumps directly affects the pressure and flow output of hydraulic systems, so it is crucial to choose high-performance and durable hydraulic pumps.
Hydraulic Valve
Hydraulic valve plays a controlling and regulating role in the hydraulic system. They can control the flow direction, pressure, and flow rate of hydraulic oil, thereby achieving precise control of movements such as lifting, rotating, and tilting of the mixing tank. Common hydraulic valves include directional control valves, pressure control valves, and flow control valves.
Hydraulic Motors and Hydraulic Cylinders
Hydraulic motors and hydraulic cylinders are the actuators of hydraulic systems, which convert hydraulic energy into mechanical energy and drive the mixing tank to perform various actions. Hydraulic motors are usually used to drive the rotation of mixing tanks, while hydraulic cylinders are used to achieve the lifting and tilting of mixing tanks.
Radiator and Hydraulic Oil Filter
The radiator is used to reduce the temperature of hydraulic oil and prevent system failures caused by excessive oil temperature. Hydraulic oil filter element is used to filter impurities in hydraulic oil, ensuring the cleanliness of hydraulic oil and preventing impurities from causing damage to the system.
These components together constitute the hydraulic system of the self loading concrete mixer truck, and they work together to ensure the normal operation and efficient operation of the mixer truck. In practical use, it is necessary to regularly inspect and maintain the hydraulic system, promptly identify and solve potential problems, in order to extend the service life of the system and improve work efficiency.
Working Principle Of Hydraulic Control System Of Self Loading Concrete Mixer Truck
The working principle of hydraulic system of self loading concrete mixer truck is based on Pascal’s law, which means that when a liquid transfers pressure in a closed container, the pressure at each point is equal. When the oil pump is working, it extracts hydraulic oil from the tank and pressurizes it. Through the adjustment of the control valve, the high-pressure oil is transported to the corresponding actuator. The executing components work under the action of oil, such as the motor driving the rotation of the mixing drum, and the oil cylinder controlling the lifting of the mixing drum. The hydraulic control system achieves various functions of the self loading mixer truck by precisely controlling the flow direction and pressure of the oil.
