1. Backpack-type triathlon squirrel-cage asynchronous high-voltage motor, high-strength anti-vibration, adapt to harsh operating conditions;
2. Low energy consumption, high efficiency, low noise and zero emissions;
3. Class F insulation level and class B temperature rise, suitable for the working environment requirements of engineering machinery;
4. Superior dynamic performance, low speed and large torque, meet the needs of various mining conditions.
1. Adopt high-reliability microcomputer protection system, with functions of missing item, short circuit, overvoltage, overcurrent protection;
2. Set up lightning protection devices;
3, three winding temperature measurement, bearing temperature detection, real-time observation of motor temperature to protect the core components of the motor.
The motor suspension system uses a self-developed motor shock absorber to reduce the vibration of the motor system.
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 is more sensitive than the 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) It is easier to control the priority of working devices.
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. The advanced sound system makes various operations more convenient and comfortable, within reach.
