1. Equipped with genuine imported Cummins engine with greater reserve power to provide longer service life.
2. The CENTRY electronic fuel control system is adopted, which can control the engine speed and fuel pressure according to the dedicated input from the electronic throttle and other equipment. 3, to achieve the best fuel efficiency.
4. The engine has good power performance, and the low speed and high torque can meet the needs of various mining conditions.
1. The multi-stage fuel filtration fuel system is adopted, with a filtration efficiency of up to 99%, which can effectively filter impurities and moisture in the fuel and prolong the life of the engine;
2. The parallel arrangement of multi-stage fuel filters can reduce the resistance of fuel injection and meet the requirements of engine fuel injection;
3. It is equipped with a transparent water storage cup and water level alarm, which can remind the user to perform water discharge operation regularly;
4. In addition, an optional electronic fuel heater can be used to solve the problem of difficult to start the engine in cold areas;
5. The fuel filter is arranged near the aisle, which is easy to maintain and maintain.
Air filtration system
1. The air filter is equipped with Donaldson SSG series heavy gray filter for mining, which can effectively prevent dust from entering and adapt to dusty environment.
2. The position of the air filter is set above the machine shed, which is convenient for disassembly, cleaning and replacement.
3. The air pre-filter is an integrally-installed pre-filter, which is easy to install and remove, and can discharge dust and impurities through the dust outlet to the pre-filter.
The engine mount system uses an independently developed engine shock absorber to reduce engine system vibration.
1. Use positive flow control system:
A) The positive flow control system enables the actions of the hydraulic pump and the main control valve to be performed synchronously, and the positive flow operation sensitivity is better than negative flow.
B) An excavator with a positive flow rate can save more fuel than an excavator with a negative flow control in the case of completing the same workload.
2. Use the main valve solenoid switch valve and proportional valve:
A) It is easier to adjust the opening degree of the spool and achieve fine operation
B) Easier control of working device priorities
1.Hydraulic tensioning system can effectively reduce the impact of walking
2.The independent cooling system can control the engine water temperature and hydraulic oil temperature in a reasonable range and improve the working efficiency of the excavator.
3.High pressure filter reduces oil pollution in the system and increases the life of system components
4.The closed-type slewing system has zero slewing flow when it is not slewing, which improves the system power utilization.
5. Large flow air filter, in order to adapt to the working conditions with large dust, adopt large flow air filter to improve the instantaneous air flow and reduce the pressure fluctuation of the fuel tank.
1. Rotary elevator is used for getting on and off, convenient and quick. Centralized filling system is adopted for centralized filling of fuel oil, hydraulic oil, slewing gear oil, transfer case gear oil, and grease for easy maintenance.
2. The power compartment adopts a modular design. The engine, engine radiator, transfer case, and pump unit are installed in the power compartment as a whole module, which is convenient for installation and transportation.
3. The whole machine adopts a single-line centralized lubrication system, which can accurately control the amount of grease and lubrication interval at each lubrication point to ensure effective lubrication.
4. It adopts overall casting to widen the track shoes, which has high strength and low ground pressure, and can be used in various working conditions.
