The hydraulic transmission device for milk turntable machine is composed of two parts: hydraulic motor and reducer.
The working oil of the hydraulic motor is No. 46 anti-wear hydraulic oil, which is provided by the hydraulic system to convert the pressure energy into mechanical energy after providing the pressure oil, and then obtains a large torque output through the reducer. The reducer is filled with No. 90 industrial gear oil. The normal oil change cycle of gear oil of the reducer is: the first oil change is carried out after 3 months of work, and the next 6 months is an oil change cycle to ensure the normal lubrication of the reducer. The hydraulic system oil change cycle is the same, it should be noted that after the release of hydraulic oil, the inside of the tank must be thoroughly cleaned, because the hydraulic system will precipitate a thick layer of oil-like impurities at the bottom of the tank after several months of operation, which are fatal to the hydraulic system, often leading to hydraulic valve jamming, hydraulic pump and hydraulic motor wear aggravation. Therefore, clean oil plays a key role in the normal operation of the whole milk turntable machine.
Other maintenance of the hydraulic system: about one month to regularly check whether the oil suction filter and the oil return filter are blocked, if there are impurities must be eliminated immediately, you can also listen to the sound of the hydraulic system during normal operation, if there is abnormal noise should be repaired immediately. The pump will produce foam and abnormal sound when suction empty, so listening to the sound of the hydraulic pump station frequently can also avoid major system failures.
In addition, always pay attention to the temperature of the oil thermometer. Milk turntable machines generally work continuously, and the control of oil temperature is particularly important, because the rise of oil temperature will cause the wear of all hydraulic components to increase. It is recommended that the index of the oil temperature gauge work below 50 degrees, because the oil thermometer shows the temperature of the hydraulic tank, such as the oil thermometer shows 50 degrees, the actual hydraulic motor and hydraulic pump have been working at about 65 degrees, so the temperature of the oil thermometer must be controlled below 50 degrees, it is recommended that the hydraulic system of each farm is equipped with a water cooler, which can greatly improve the service life of the milk turntable machine.
The hydraulic transmission is the actuator on the milk turntable machine, so it is particularly important. We must maintain frequently, in addition to the periodic replacement of reducer gear oil, the new replacement of the hydraulic transmission device must also pay attention to the following matters: (1) must ensure the parallelism of each hydraulic transmission device and the turntable, to ensure that the rubber wheel and the turntable are parallel meshing, if it is found that the rubber wheel is easy to wear or the hydraulic transmission device is often damaged, it should be paid attention to. (2) A turntable is driven by 4 hydraulic transmission devices, and the force balance of 4 transmission devices should be ensured during installation, that is to say, the tightness of the tension of the spring is very critical, such as adjusting too loose transmission device can not output torque, such as adjusting too tight will lead to transmission bearing damage and rubber wheel wear is serious. Therefore, reasonable installation is also to ensure the normal operation of the milk turntable machine. (3) The hydraulic motor leakage oil pipe should be immediately upward after it comes out to ensure that the inside of the hydraulic motor housing is filled with hydraulic oil, because the lubrication of the hydraulic motor depends on the hydraulic oil itself, and the leakage oil pipe must be directly returned to the oil tank, not connected with the main oil return circuit or connected to the oil return oil filter, this problem has occurred before Feidong Ranch. The leakage oil pipe is connected to the oil return filter after returning to the oil tank, when the oil return filter element is blocked and the oil leakage is returned to the oil tank normally without oil, and the pressure of the hydraulic motor housing rises to cause oil leakage, so the leakage oil pipe must be returned directly to the oil tank. (4) When the maintenance personnel find that the output of the milk turntable machine is weak, they can check the amount of oil flowing out of the leakage oil pipe of the hydraulic motor. Milk turntable machine is driven by 4 hydraulic motors, each hydraulic motor has a separate leakage oil pipe, maintenance personnel can judge whether the hydraulic motor works normally according to the leakage oil flowing out of each hydraulic motor, if it is found that the leakage oil flowing out of the hydraulic motor is in the shape of a jet, it means that the hydraulic motor has been damaged and should be replaced as soon as possible. If the leaking oil flowing out of the 4 hydraulic motors is normal and the turntable machine is still weak, you should check whether the rubber wheel is engaged normally, if the rubber wheel is also normal, the cause is likely to be damage to the hydraulic pump or stuck hydraulic valve.
