Caractéristiques du produit

●Traveling speed realizes stepless speed change

The driving hydraulic system is a closed circuit composed of a manual servo two-way variable plunger pump and two fixed plunger motors.,The manual servo bidirectional variable plunger pump is connected with the diesel engine through the transfer case.,Two fixed plunger motors respectively drive the front and rear vibrating wheels to travel through the planetary reducer.,By pushing the handle of the manual servo valve on the drive pump,The road roller can realize stepless speed change and advance.、The function of retrogression。

●Double Steel Wheel、Dual drive、Double amplitude

Double drive of front and rear wheel,Ensure that the roller has good driving performance,The two vibrating wheels are driving wheels.,And is favorable for improving the quality of the pavement.,Front and rear wheels vibrate(It is also possible to vibrate the front or rear wheels individually),And improve that work efficiency and the compaction quality.。

●And that brake is safe and reliable

The drive hydraulic system is a closed circuit,When the manual servo handle on the drive pump returns to the neutral position,Drive pump and swashplate centering,The displacement of the drive pump is zero,Drive hydraulic system neutral self-locking stop,Road roller to realize service braking。

The two planetary reducers that drive the front and rear wheels are equipped with multi-disc brakes.,When the diesel engine shuts down or the brake valve coil on the drive pump loses power,Brake oil control oil cut-off,Play a braking role,Reliable parking brake of road roller。

When the service brake fails due to the damage of the pressure oil pipe or other components in the driving hydraulic system and an emergency occurs,Emergency braking measures can be taken.,The emergency stop switch is pressed,Power loss of brake valve coil on the drive pump,Cut off the oil in the oil chamber of the controller,Braking function of brake,Road roller to realize emergency braking,At the same time, the manual servo valve also makes the swash plate of the drive pump return to the center due to oil cut-off.,The displacement of the drive pump decreases to zero.,The safety of the man-machine is effectively protected.。

●Achieve short distance dragging

When the road roller is out of order and unable to run by itself,It shall be towed away from the construction site in time.,So as not to affect the construction,XG6071DThe driving hydraulic system of the tandem vibratory roller adopts the patent technology---Manual oil supply and towing hydraulic mechanism of road roll(Patent No:ZL00 2 29862.7),This function can be easily realized.。

When the roller breaks down(For example, the diesel engine cannot be started.)When unable to walk on its own,By operating the ball valve installed between the high and low pressure oil chambers of the drive hydraulic system,,O that the high and low pressure oil chambers of the hydraulic system of the driving valve are communicated,Manually supply oil to the brake oil chamber by operation.,Leave the brake in the released state,Use other existing traveling machinery on the construction site for traction,Short distance dragging can be realized,Remove the failed roller from the construction site.。

●Vibrations can start and stop quickly

High grade highway has a high requirement for the smoothness of asphalt pavement.,Unevenness of the asphalt surface due to local over or under compaction of the asphalt pavement shall be avoided,Therefore, compaction equipment for asphalt pavement is required.─The vibration stop or start speed of the tandem vibratory roller shall be fast.。

BecauseXG6071DThe high quality relief valve is used in the vibration hydraulic system.,Its response time is short.,About 20ms,The set pressure of the relief valve is much higher than the working pressure of the vibration system.,It can ensure the rapid start of vibration.。The front and rear wheel vibration hydraulic system is an independent closed hydraulic system.,When the swash plate of the vibratory pump returns to the neutral position,The vibration can stop quickly.。

●Start and stop of vibration、Sprinkler can be controlled automatically or manually

Set the vibration and sprinkling in the automatic control state according to the work requirement,According to the preset speed,When the travel speed of the roller reaches the set value,Automatic vibration and automatic watering;Vibration and watering can be stopped automatically when the driving speed of the road roller is reduced to the set value.。

●Adopt the products of famous international companies

XG6071DDrive pump、Vibrating pump、The vibration motor is usedSAUER-SUNDSTRANDThe company's products,Vibrating bearings are usedSKFThe company's special vibration bearings,Sprinkler pump is usedFLOJETThe company's products,The drive motor and the planetary reducer adoptREXROTHThe company's products,Used for electrical instrumentsCURTISThe company's products,The battery is usedOPTIMAThe company's solid battery。

●The front and rear wheels are independent vibration system

The vibration hydraulic systems of the front and rear wheels are mutually independent vibration hydraulic systems consisting of a vibration pump and a vibration motor respectively.,The vibration of each vibration wheel can be switched freely during operation.;Damage to hydraulic parts does not affect each other。
