How to connect the hydraulic oil pipe of the automatic mixer? A friend often buys the hydraulic oil pipe of an automatic mixer, and doesn't know how to modify it. We need to understand its working principle.
The power take-off on the chassis of the automatic mixer transmits the power of the engine of the automatic mixer to the hydraulic oil pump to generate high-pressure hydraulic oil. The high-pressure hydraulic oil drives the hydraulic motor to rotate at high speed, and the reducer generates large torque to drive the mixing drum to rotate. According to the principle of spiral transportation, the blades in the mixing drum continuously promote concrete mixing to avoid concrete setting.
The power output from the engine of the automatic mixer truck is transmitted to the hydraulic oil pump through the power output. The hydraulic oil pump is equipped with two oil pipes, one connected to the hydraulic oil tank and the other connected to the hydraulic reversing valve (the thickness of the two oil pipes is different). The directional valve has four ports, two of which are connected to the hydraulic motor and the other to the outlet of the hydraulic oil radiator.
In addition, we should also know the advantages of hydraulic transmission: it can realize the stepless speed change control of the mixing tank, and the rotation speed and direction of the tank can be adjusted arbitrarily within the set range. The hydraulic system device is light in weight, small in volume, convenient in installation and flexible in connection. The hydraulic system operates stably, with small vibration, small buffer when reversing, and convenient operation. With automatic overload protection device, self lubrication, long service life. Hydraulic components are highly standardized and easy to repair and replace.
In addition, during the operation of the hydraulic system of the automatic mixer truck, various impurities and foreign matters will inevitably be produced in the oil, mainly including welding slag, paint, rubber, abrasive, dust, moisture, and colloidal substances generated by oil oxidation. These impurities caught in the moving parts of the hydraulic pump motor will damage the lubricating oil film between the parts, scratch the plunger, oil distribution plate, various valves and other sensitive parts, cause pressure leakage and high temperature, and shorten the service life of the pump motor.
If the large particles block the damping hole of the control oil circuit or block the valve core, the equipment will also lose control instantly. If a can of concrete cannot be released in time, it will cause very large associated losses; If the hydraulic oil is not replaced for a long time, the performance of the oil will gradually decline, resulting in weak work, heat, and high temperature, and serious deterioration of the oil, which will damage the internal parts of the pump motor.
Later, there will be answers to the questions about how to connect the hydraulic oil pipes of the automatic mixer truck. You can use this as reference information. Of course, if you have any uncertain choices or matters, you can come to our website http://www.sdzkjf.cn Understand!
