Այն բեռնատար կռունկ, with its multi-functional capabilities and wide range of applications, has gained significant popularity in the market. It’s important to note that the crane component of the բեռնատար կռունկis controlled by a hydraulic system, and the hydraulic oil within this system requires regular replacement. Այսպիսով, do you have a clear understanding of the criteria for replacing this hydraulic oil? And how can you determine whether it’s time for a replacement?
We typically determine whether a replacement is necessary by identifying the viscosity of the hydraulic oil. There are two common identification methods:
Inverted hydraulic oil method: Extract the hydraulic oil from the hydraulic oil tank and obtain standard hydraulic oil. Place them respectively in two identical transparent glass bottles of the same size and seal the bottle mouths. Position the two bottles side by side and invert them. If the bubbles of the tested hydraulic oil rise more rapidly within the bottle compared to those of the standard oil in the other bottle, it indicates that the viscosity of the tested hydraulic oil is lower than that of the standard hydraulic oil. Conversely, if the bubbles rise more slowly, it implies that the viscosity is higher. If the bubbles in both bottles ascend at a similar pace, it suggests that the viscosities are comparable and no dilution is necessary.
Let’s elaborate on this method. The rate at which the bubbles rise is directly related to the viscosity of the oil. A lower viscosity allows the bubbles to ascend more quickly as the fluid offers less resistance. A higher viscosity, մյուս կողմից, slows down the bubble’s ascent. This simple but effective test provides valuable insights into the condition of the hydraulic oil.
Glass plate tilting method: Take a clean glass plate and position it horizontally. Deposit a drop of the extracted hydraulic oil on the glass, and simultaneously, place a drop of standard hydraulic oil adjacent to it. Tilt the glass plate and closely observe the flow rate and the distance covered by the oils. If the flow rate and the distance traveled by the tested hydraulic oil are both greater than those of the standard hydraulic oil, it indicates that the viscosity is lower than that of the standard oil. Ի հակադրություն, if the flow rate and distance are smaller, it suggests a higher viscosity.
Now, let’s discuss the process of replacing the hydraulic oil:
Նախ և առաջ, drain the existing hydraulic oil within the hydraulic oil tank. Thoroughly clean the tank to remove any sediment, debris, or contaminants that might have accumulated. Once the tank is clean, proceed to add fresh new hydraulic oil.
During the cleaning process, it’s essential to use appropriate cleaning agents and tools to ensure all impurities are removed. Any residual dirt or old oil can compromise the quality and performance of the new hydraulic oil.
Remove the main circuit pipe and start the engine, allowing it to idle to operate the oil pump. This step helps to prime the system and prepare it for the subsequent oil replacement process.
The idling of the engine at this stage ensures a gentle and controlled flow of oil through the system, reducing the risk of sudden pressure surges or damage.
Operate each mechanism individually. This action enables the hydraulic oil to push out the old oil within the circuit one by one. Continue this operation until fresh new oil starts flowing out of the main return pipe.
By operating each mechanism separately, you ensure that the old oil is completely purged from all the circuits and components, ensuring a thorough replacement.
Վերջապես, reconnect the main return pipe to the oil tank and replenish the new oil to the tank up to the specified level.
Although this oil change method might be somewhat time-consuming, it offers significant benefits in terms of protecting the integrity and performance of the hydraulic system.
The hydraulic system of the բեռնատար կռունկtransporter is of paramount importance. Different բեռնատար կռունկs might feature hydraulic systems from various brands, but the fundamental maintenance principles remain similar. It is sincerely hoped that everyone takes the maintenance of theբեռնատար կռունկ‘s hydraulic system seriously.
Regular and proper maintenance of the hydraulic system not only extends the lifespan of the equipment but also ensures its efficient and reliable operation. Neglecting this aspect can lead to performance degradation, increased wear and tear of components, and potentially costly breakdowns. By adhering to the correct procedures and schedules for hydraulic oil replacement and system maintenance, you can maximize the productivity and safety of the բեռնատար կռունկ.
