The hot summer has come quietly, especially for everyone to summarize how to maintain the loader in summer. Below we summarize how to maintain the hydraulic system of the loader and how the driver spends the hot summer.
The movement of the loader is complicated. All organizations often start, brake, commutate, change the load, shock and oscillation frequently, and the field work, the temperature and the geographical position change greatly, plus the hot summer climate, so according to the loose loader The operating characteristics and environmental characteristics of the hydraulic system should:
1) With high transmission efficiency, it can give full play to the power and fuel economy of the engine.
2) Adjust the coarse, stiff, and vibration-resistant cooler to reduce the total heat generation of the system, so that the hydraulic oil temperature does not exceed 80 degrees during the continuous operation of the host, or the temperature rise does not exceed 45 degrees.
3) The hydraulic system and hydraulic components have satisfactory reliability under the effect of large load changes and rapid oscillation impact.
4) Due to the large amount of dust on the site of the loader, the hydraulic oil is simply contaminated, so the sealing function of the hydraulic system is better, the sensitivity of the hydraulic components to oil pollution is low, and the entire hydraulic system must be equipped with an oil filter and a dustproof device.
5) Choose hydraulic or electro-hydraulic servo control device, so that the loader sets an automatic control system, and then improve the loader skills and reduce the driver's labor intensity.
The hydraulic system must ensure the following points to fulfill these requests:
1) Make sure that the loading manipulator, arm and bucket can move independently of each other, or they can cooperate with each other to complete the compound action.
2) The operation of the working device and the reversal of the turntable can be stopped individually or in combination.
3) The left and right crawlers of the crawler loader are driven separately, which makes the excavator easy to walk and turn around, and can turn on the spot to check the liveness of the loader.
4) Make sure that all the actions of the loader are reversible and steplessly variable.
5) Ensure that the loader operation is safe and reliable, and that each fulfillment component (hydraulic cylinder, hydraulic motor, etc.) has good overload protection; the reverse organization and walking device have reliable braking and speed limit; prevent the boom from being fast due to its own weight Descent and speeding down the whole machine.
The summer weather is very hot. On the one hand, the driver's energy consumption is large, and it is simple and tired. On the other hand, the high temperature of the whole machine is also prone to shortcomings, so both must be adjusted in time, even if the loader is added with oil suitable for summer, and the Looking at the cooling system, although the high temperature in summer makes it unbearable for both the loader and the loader, the loader must be well maintained, so that the cost of repairing the loader parts can be saved and the loader can add revenue. In summer, the air conditioner in the cab should be repaired and adjusted so that the driver's condition can be better adjusted.
Do the above points well, and choose more and more high-quality loader accessories to achieve their best conditions, so that the loader can smoothly through the hot summer.
