Correct use of lubricating oil for full-automatic hydraulic brick machine


Correct use of lubricating oil for full-automatic hydraulic brick machine_ Selection and use of hydraulic oil_ Oil leakage problem

Only mechanical equipment can not be exempted from the use of lubricating oil, especially for machinery of hydraulic system, lubricating oil needs to be used correctly. Of course, the full-automatic hydraulic brick machine will also use lubricating oil. Then, how to use lubricating oil correctly? Let's talk about how to use the lubricating oil of the full-automatic hydraulic brick machine correctly.
What aspects should be paid attention to when selecting and using lubricating oil for full-automatic hydraulic brick machine:
When users choose lubricating oil for brick machine equipment, they must see clearly that what you buy is new oil, not old oil. Compared with new oil, the old oil has dim color, serious ambiguity, astringent hand feel, and the impurities in the oil (including metal chips, sand and dust particles, colloidal sediment, etc.) are significantly increased or emulsified.
If you choose to use oil products of different brands than before, you must open the oil drain plug to drain the old oil when the brick machine is hot and various impurities are in suspension, then add kerosene and a small amount of new oil to the standard oil level, drain it after running for 3 ~ 5mm, wipe the oil filler, check and dredge the ventilation or air filter, Fill the new oil to the standard level with a clean filler bucket. When approaching the standard oil level, add oil slowly, observe the scale of the oil scale or dipstick, or unscrew the oil level screw. When there is oil overflow, stop oil filling, seal the oil filling port, insert the dipstick or tighten the oil level screw.
If the grease is to be replaced, clean the old oil in the brick machine with kerosene before disassembling, overhauling or updating the bearing. After draining, add grease according to the specified amount of grease. Generally, the amount of grease is 1 / 3 ~ 1 / 2 of the oil chamber. Apply the new grease in place with a wooden shovel or finger and reinstall it.
During normal equipment maintenance, the oil tank, oil pipe, joint, seal and other hydraulic components shall be carefully cleaned according to the process procedures to remove chips, burrs, rust, oil stain and other mechanical impurities, and dried with clean and dry compressed air.
The solution to the problem of oil leakage in the hydraulic system of the full-automatic hydraulic brick press,
The solution to the problem of oil leakage in the hydraulic system of the full-automatic hydraulic brick machine. The hydraulic oil can be said to be the "blood" of the full-automatic hydraulic brick machine. Once the oil leakage occurs, it indicates that there is a serious fault problem in the hydraulic system of the hydraulic brick machine, which will affect the service life of our machine, or lead to the "strike" of our hydraulic brick machine. Therefore, we must pay special attention to whether there are hidden dangers such as oil leakage in the hydraulic system of the brick machine in production. Let's look at the solutions when the machine leaks oil.
First of all, we should do a good job in daily maintenance, focusing on prevention. For those who often use the equipment, we must pay attention to safety in daily operation. Everyone should know the hidden dangers of safety production caused by oil leakage. So how to prevent it? When there is oil leakage in the hydraulic system of the hydraulic brick machine, events such as part wear should be one of the first factors to be considered, because this is the most common reason. However, for this situation of different machines, it should be observed first and should not be treated the same.
Secondly, we should check the fuel injection valve of the machine in time. When the fuel injection valve is large, the fuel injection quantity is large. Normally, the grease flows from the spray hole to the hollow shaft. If the oil quantity is too large, it will splash to the felt oil seal outside the oil slinger and leak out. In case of this problem, professional technicians are required to adjust the oil quantity of the fuel injection pipe to ensure good lubrication of the bearing, There will be no large temperature rise or even tile burning due to lack of oil.
Then we do the daily maintenance work. After the hydraulic brick machine runs for a period of time, the oil hole on the oil injection pipe is blocked by dust, the oil pressure in the oil pipe rises, the oil injection near the oil slinger hole increases, and the oil splashing outside the oil slinger will also cause oil leakage. Therefore, the oil injection hole should be dredged and cleaned frequently. Another method is to ask the hydraulic brick machine manufacturer to expand the diameter of the oil injection hole in advance, so as to ensure the lubrication of the bearing bush, not easy to form blockage and reduce the probability of oil leakage. This will not easily happen again.
These are some of the main reasons for oil leakage in the hydraulic system of the hydraulic brick machine that we have specially summarized for users in our daily work. When this happens, we must not be careless or panic. We should try our best to keep ourselves calm, and then solve them one by one through these treatment methods and relevant reasons we have summarized for you.
