1 Main technical parameters Running speed Outside construction machinery 2002 Engine type Power quasi-speed kWrmin Maximum torque, 1 Dimensions 1 2 Main structure and technical features Hydraulic vibratory machinery-driven articulated full-hydraulic steering; double-frequency double amplitude vibration quality, work efficiency. Hydraulic pump and motor selection of Sao Sang Sang 90's products, vibration bearings use Sweden's 3 that is the bearing, reliable performance.

2.1 Power System The engine uses the Shanghai-produced 06420 supercharged diesel engine. The machine features stable, reliable quality, low fuel consumption, low noise, clean and environmental protection, rated power is 132kW, rated speed is 2000rmin, and power reserve is large, which improves the reliability of the whole machine.

2.2 Drive system The drive system is driven by a mechanical transmission rear axle. The forward and reverse gears and the gear shift are achieved through the transfer case and gearbox 2.

The transfer case is mainly used for power distribution. The power transmitted from the engine is transmitted to the vibration system and partly to the drive system. The transfer box can change the walking direction of the roller by changing the meshing gear to achieve forward and backward; the gearbox can make the roller get different walking speeds in high, medium and low gear; the drive axle is selected by Xuzhou Meichi Axle Co., Ltd. and manufactured by Rockwell Technology. The special vibrating roller is equipped with a anti-slip differential and a caliper disc brake inside the bridge for reliable performance. The tire uses a low-pressure tubeless engineering tire. The tire is internally filled with a liquid weight, which simplifies the structure of the vehicle, lowers the center of gravity, and improves the stability of the vehicle.

2.3 Vibratory System The vibratory system 3 is a closed circuit, hydraulic transmission, with a stable start of vibration, high efficiency. The vibratory wheel uses two independent vibratory chambers and is equipped with an independent eccentric structure. The vibration is controlled by a vibration switch mounted on the control panel of the console to control the vibration amplitude and excitation force of the pump. Vibration bearing selection 1. Steering cylinder 2. Steering gear 3. Steering pump 4. Vibrating motor 5. Vibrating pump 6. Fine filter 7. Radiator 8. Primary strainer 9.

Tank 10. Air filter SKF bearing, reliable performance. The vibration pump uses a swash plate axial piston variable displacement pump with a solenoid valve equipped with 2 multi-function valves to set the system pressure and protect the components in the system; Oil, to make up for leaks when the system is working; to make the two circuits in the main circuit communicate. The pump is equipped with a displacement control screw to set the displacement of the pump. The vibration motor is a dosing motor with a flush valve, which accelerates the circulation of the oil in the motor housing, reduces the operating temperature of the motor, ensures the cleanliness of the oil in the motor housing, and improves the working environment of the motor.

2.4 Steering System Steering system 3 is fully hydraulically articulated steerable, with a small turning radius and light and flexible handling. It is installed on the front steering wheel of the engine to drive the full hydraulic steering gear, so that the pressure oil enters the hydraulic cylinder through the metering motor, so that the piston rod of the cylinder can be expanded and retracted, so that the front and the back of the roller can be turned around the hinge point to perform steering. When the roller runs straight, the pressure oil is directly returned to the tank via the steering valve in the steering gear; when the engine is off, the steering wheel is turned and the cycloid motor in the steering wheel acts as a manual pump, which can make the roller slower .

2.5 Easy to maintain, easy maintenance of articulated beam frame, so that all components have the best accessibility, easy maintenance and maintenance of the vehicle; level cab and sound-absorbing cab to provide drivers with safe and comfortable work surroundings.

The Seal, also called [oil seal
", the function of the oil seal is to stop whatever fluid is inside from leaking out the clearance between the shaft and housing. The seal may also be used to prevent outside materials, such as dirt, from moving in through the clearance.
Nitrile oil seal is widely used in many applications, including that oil resistance is needed or which low temperature functionality is required. These include automotive, aircraft fuel systems, marine applications and more.
Benefits: Excellent abrasion and tear resistance, cost effective
Limitations: Nitrile is not good at resisting degradation by ozone or weather.
