  2. Oil leakage of common faults of vibrating hydraulic brick machine

     2020/5/18

    he reason for the oil leakage of the vibration box of the hydraulic brick machine may be the quality of the box, the quality of the oil seal, the quality of the lubricating oil, the air pressure inside and outside the box, etc. If too much lubricating oil is added, it will also cause overflow. What about oil leakage from the vibration box of the brick machine? Xiamen Boerwo Machinery Owen answers how to prevent the oil leakage of the vibration box of the hydraulic brick machine?


    Method / step by step:


    1. The internal pressure of the vibration box of the hydraulic brick machine is greater than the external atmospheric pressure is the main reason for the oil leakage. The greater the pressure difference, the more serious the leakage. Therefore, reasonable pressure equalization measures can be taken. If the vent cap and vent plug are designed on the tank cover, if the diameter of the vent cap and vent plug is too small, it will increase the internal and external pressure difference and cause oil leakage. Therefore, the main check should be made when selecting. The upper cover of the vent cap can be opened. After a few minutes of high-speed operation of the reducer, the vent hole should be touched by hand. If there is hot air, the aperture is too small. You can change a large vent cap.


    2. The oil return of the vibration box of the hydraulic brick making machine is not smooth. The oil splashed on the inner wall of the box cannot flow back to the oil pool in the box as soon as possible, and it may gradually leak outward along the axis. To make the oil accumulated on the inner wall of the tank or the shaft section flow back into the tank as soon as possible, these two methods can usually be used: 1) An oil seal is set on the vibration box head of the hydraulic brick machine, and the oil spill is used to block the oil leakage. Let it flow back to the oil sump. 2) An annular oil return groove is designed on the parting surface of the machine base, so that the oil flows back into the tank, and part of it flows to the bearing for lubrication.


    3. If the lubricating oil leaks due to the poor quality of the casting, you can first clean it with gasoline, etc., then inject 20% hydrochloric acid, remove the hydrochloric acid and clean it one day later, rely on the chemical reaction to generate ferrous chloride to block the trachoma or gap .

    4. Use high-temperature, wear-resistant barrel machinery special grease, or one-third of the gear oil, two-thirds of the butter is well blended, it is recommended not to add gear oil;
