In all normal work of the small excavator, the temperature of the hydraulic press management system is not easy to exceed 50 °C. Once it exceeds 50 °C, the management system may become hot, and if its temperature is greater than or equal to 80 °C, It may cause the shortcomings of the hydraulic press management system of small excavators, and the hydraulic press management system is gradually hot .

If the hydraulic press management system of the small excavator gradually shows a hot situation, it will cause the following series of problems: the working pressure of its work is reduced, the power is insufficient, the output power output is unstable, the operation and care failure, etc., and also It will endanger the continuous work of the hydraulic press management system and cause fatigue. Therefore, it is necessary to make a diversified analysis of the shortcomings of the small excavator hydraulic press management system, and carry out immediate precautions to ensure the stable operation of the small excavator hydraulic press management system.

1. The hot effect of the hydraulic press management system of the small excavator. In the process of the application of the small excavator, the hot hydraulic press management system of the small excavator is a disadvantage that causes repeated problems, and its analysis and solution process is still relatively speaking. Very disorganized. At the beginning of the defect, all functions work normally, but with the continuous rise of the temperature in the hydraulic press management system, some obvious abnormal problems will appear after one hour of continuous work, and endanger everything in the hydraulic press management system. Normal work, prompting its internal organizational system to work slowly, the scope of exploration is not good. Therefore, if the hot fault of the small excavator is not solved immediately, it will cause great harm: ① The viscosity of the hydraulic oil is reduced, which increases the possibility of leakage, and promotes the heating of the management system. vicious cycle; ② the air oxidation rate of the hydraulic oil is accelerated, and the small round holes of the components are blocked, which endangers the application of the hydraulic system; ③ the simple composition of the plastic hose becomes brittle, and the rubber products are ineffective; ④ aggravates the damage of the gasoline pump and the hydraulic solenoid valve damage, or even cause its failure, and cannot be used. ,Analysis of the hot and shortcoming of the hydraulic press management system of the small excavator, 2 factors that endanger the hot management system of the hydraulic press of the small excavator, 1) The system architecture is unscientific, the parts are not up to standard, the unscientific structure of the hydraulic press system and the improper operation may be Its parts are not good enough, such as the pipeline of gear oil is too thin when working, the capacity of the car fuel tank is too small, the pipeline of gear oil is not 90°, and the heat removal ability of the car fuel tank is poor, etc., all of which will cause digging. The heat of the hydraulic press management system.

2. The viscosity of the gear oil is low. The gear oil in the hydraulic press management system of the small excavator is viscous. When the temperature rises, the viscosity of the gear oil will decrease. At this time, it is easy to cause the leakage of the management system and endanger the small excavation. The working output power of the machine. Moreover, the gear oil has a smooth effect, and its viscosity is reduced, the protective film formed on the surface of the management system will become soft, the effect will be reduced, and the damage will be aggravated when the surface is exercised, and the application rate of components will also be reduced. will decrease. In addition, the unscientific application and repair of the hydraulic press management system will increase the possibility of the management system becoming hot. For example, the fact that the actual operation staff blindly follow the trend of oil supply will cause the oil level of the shock absorber tank to be too high, and the management system may become hot at this time; the unscientific repair of the hydraulic press management system will harm the work of the management system. There is a possibility of causing the management system to become hot.

3. The method to solve the hot problem of the hydraulic press management system of the small excavator, (1) to improve the setting of its heat pipe heat dissipation, the setting of the heat pipe heat dissipation in the small excavator is the guarantee for the normal operation of the small excavator hydraulic press management system. The cooling tower can be set up in the hydraulic press management system, to ensure the natural ventilation effect of the cooling tower, carry out an immediate inquiry on the cooling tower's heat exhaust pipe and the transmission belt of the electric fan, improve its heat dissipation effect, and carry out cleaning anytime and anywhere, for the This ensures the heat removal efficiency of the cooling tower. , Be cautious when choosing hydraulic oil filter elements. Because the heat removal baffle is set in the fuel tank of the car, if its insulation effect is weak, it will return to the hydraulic press management system after the cycle time of the hydraulic oil to work. Therefore, it is necessary to carry out a real-time monitoring system for the liquid level aspect ratio in the automobile fuel tank to ensure that it is within the overall planning of everything normal. When carrying out inspection and supervision, you can insist on the vertical type of the arm of the small excavator and the ground, so that the bucket is not very good to touch the ground, and use the car fuel tank level gauge to check the hydraulic oil level. When the car oil tank is refrigerated, make sure that its liquid level gauge is in the middle of the center line and the exit, and when the oil is rolling, the level gauge is smaller than the release. If the level gauge exits lower, the gear oil must be compensated immediately. , Analysis of the hot and shortcoming of the hydraulic press management system of the small excavator, (2) Effective application of the components of the hydraulic press management system, 1) When carrying out the application of the small excavator management system, it is necessary to ensure that the work pressure accepted by its work is effective. the overall plan. It is because, if the overall planning of the working pressure is exceeded, the temperature in the hydraulic press management system will rise, jeopardizing its normal work; if the working pressure of its management system is too low, open the preset working pressure of the speed control valve. If the value is relatively low, it will cause different levels of damage to its pressure relief function, which will easily cause the oil circuit board to be opened again and again, which will cause the management system to overflow again and again and become hot. Therefore, it is necessary to effectively set the working pressure accepted by the work of different oil circuit boards in the hydraulic press management system. , 2) Different applications of the hydraulic system in the hydraulic press management system will damage its components to different levels, so pay attention to its application and repair. Assuming that the damage of the components exceeds the inevitable overall planning and jeopardizes its application efficiency, it will cause the management system to leak, the oil temperature will be high, and then cause the management system to fail, and the management system will gradually become hot. There are two types of leakage in the hydraulic press management system: internal leakage and external leakage. The main hazard factor of high oil temperature in the management system is still leakage. Assuming that the leakage situation is not optimistic, the output working pressure of the pump casing will not be optimistic, and the power will not be able to satisfy its regulations. Therefore, it is necessary to carry out effective application of its components, and carry out timely inquiry and replacement to reduce its management system. possibility of leakage. When replacing the gear oil, it is necessary to carry out a multi-directional inquiry of the hydraulic oil filter element of this product every time to prevent it from being stuck.

4. In the application of small excavators, the operation of the hydraulic press management system has always been valued, which is related to the hydraulic press management system itself. The application of the hydraulic press management system drives the function of the commodity, effectively reduces its energy consumption, and can be consistent with the function of the server, and its operation function is also a huge drive. However, the hydraulic press management system of the small excavator often shows hot defects, which greatly jeopardizes its normal work and causes different levels of damage to the surrounding natural environment. Therefore, it is necessary to do a variety of analysis on the harmful factors of its hot, and to carry out a fundamental study on it, to improve the professional skills of the hydraulic press management system, and to reduce the possibility of its hot defects.
