The 1st hydraulic excavator was designed successfully by the French Poclane manufacturer. Because of the application of hydraulic technology, in the 1940s, a hydraulic backhoe was developed on the tractor suspension-kind excavator. The typical excavator structure includes a power device, a working machine, a rotary mechanism, an operating tool, a transmission mechanism, a walking mechanism, and auxiliary structures. The 3 most essential parameters of excavator supervision are operating weight (mass), engine power, and bucket capability. I expect to see your excavator assistance in destiny!
(1) To guarantee the satisfactory performance of the method is compact cooling device, before penetrating the spring, should look at the diverse parts of the cooling technique is a complete scan times, tense and lubricity, counting as cleansing the size of the cooling procedure(including thermal scale on a neat sweep frequency), the advanced cooling efficiency, cooling system, to maintain smooth of inertia and the speed of the cooling water has been replicated.
(2) Research and analyze the driving instrument and the strap of the water pump, and the electric fan. After prolonged-term application, the driving man and strap will create exhaustion and deformation, which will decrease the cooling impact of the system. When the transmission belt is returned, concentration should be delivered to the different styles and lengths, and the accurate adjustment of the tightness of belt.
(3) The examination and the water tank joint hose, the oil resistance assessment of the water tank hose is insufficient, the early evolution of hard deterioration, so that the sociable response water reserve, forcing students to start the car man-machine height is too high. Examination of the break and water leakage stage, to ensure convenient and practical elimination.
At the exact time, to maintain a relatively acceptable amount of cooling water, the capability to notice the lack of convenient addition.
(4) To ensure the accurate operation of the whole apparatus, timely concentration should be paid to the assignment of the water temperature meter, and dimensions should be accepted when the temperature exceeds 90°. You can select the nearest shade to idle down to cool down, pay attention not to presently turn off, to control the engine's man-machine interior overheating induced by the cylinder waiting calamity.. After the measure declines, we should also examine the electric fan drive belt pull matters..
(5) into a spring can be before a needle to look at all elements of the lubrication management design components to do an interpretation analysis test, to assemble the butter storage plan, and the gearbox storage plan is accurate. Look at the oil in the gearbox, distance variable, and driver axle by completing a knowledge system survey, from the quality of the oil to the amount of oil, and to be capable of keeping the command oil clean.
(6) in the summer awning, the digit of tire coatings of the small loader in the inside and outside more than 14 layers, heat transfer is more immediate than the large tire, it is challenging to emerge tire overheating, so that the memory improvement, promote the tire rubber performance, so that the tire burst. If you are familiar that tire gas is being held and the tire count is too elevated, you should stay in the shade and cool down before driving. It is not authorized to use deflating strategies to decrease air storage in the tire or to pour cold water on the hot tire.
(7) Repeatedly investigate and examine the brake efficiency of the entire machine, to catch and destroy the failure of the comprehensive design management of the brake as soon as practicable, and prevent traffic casualties.
Long-term work functional application of braking, a measurement of the brake hub and one piece is too elevated, arrangement on braking and people, should be capable of instantly stopping the cooling, lest it bring hazards to the machine design personnel's safety, a hidden crisis. Nonetheless, it is not authorized to use cold water to pour the brake to force cooling.
(8) Secure battery electrolyte level height; The moderate temperature in summer is high, the boiling amount is enormous, and the liquid level increases fast. According to the proof and the passion, the steam water or electrolyte (pay attention to its innocence) is not counted in time, so that the liquid level is 10 to 15mm higher than the top plate of a plate structure, so as to control students from influencing the oxidation of the plate.
