1. Adopt humanized design
The appearance of bulldozers produced in my country and the layout of the cab are still far behind those of advanced countries in the world. This has little to do with the competition in my country's bulldozer industry. In view of my country's entry into the WTO and the gradual removal of trade barriers to foreign equipment, we must follow the example of foreign advanced enterprises and attach great importance to the appearance of our products and the comfort of the cabin interior. The control system is gradually approaching the excavator and automobile industries to reduce the driver's labor intensity. The instrumentation adopts the electronic monitoring device with three-level alarm and the automatic fault diagnosis device. The cab adopts a closed, air-conditioned cab with an air filter device, and adds advanced electronic equipment such as a radio recorder and even a DVD to maximize the humanity of the driver.化Requirement.
2. Application of energy-saving technology
1. The hydraulic system of the working device adopts constant differential overflow technology. In this way, when the working device reversing valve is in the process of small opening throttle speed regulation, the excess oil supplied by the oil pump can be returned to the fuel tank without the safety valve, but directly overflows from the differential pressure valve back to the fuel tank, so that the system pressure during the speed regulation process is only higher than the working pressure. High a certain value of △P to achieve the purpose of reducing hydraulic power loss and lowering oil temperature.
2. The hydraulic system and transmission system of engine and working device adopt full power matching technology. The engine can automatically adjust the power output to the transmission system and the hydraulic system of the working device according to the actual working conditions, so as to maximize the use of the engine power to achieve the purpose of energy saving.
3. Hydrostatic transmission technology. The transmission adopts hydrostatic transmission. The whole machine reduces transmission components such as gearbox, torque converter (main clutch), steering clutch, etc., thereby greatly reducing mechanical power loss, and it is easy to achieve full power matching with the engine to achieve energy saving purposes.
3. Engine emission reaches Euro Ⅱ standard
With the increase in the construction and maintenance of transportation and infrastructure in large and medium cities, and the gradual stricter environmental protection requirements in domestic and international markets, engine emission requirements have reached at least Euro I standards, and some developed countries have even requested Euro II standards. Therefore, the engine equipped with bulldozers must meet this market requirement as soon as possible.
