1, vibratory roller and static vibratory roller comparison, under the same conditions of quality, tamping fruit, tamping after the basic density, reliability, vibratory roller better than static vibratory roller.

2. When the specified compactness is the same, the number of tamping passes is less than that of static vibratory rollers.

3、Because of the use of L-band compactometer in vibratory roller, the driver can find out the weak links in the construction of the road, and take remedial measures at any time and anywhere, which greatly reduces the risk of quality.

Prevention of oil seepage on vibratory rollers

During the operating life of a vibratory roller, the vibratory shaft and the vibratory roller bearings are subjected to alternating vibratory loads that vary from cycle to cycle. Because the vibratory shaft rotates at high speeds, a lubricant must be used. Generally, the grease in the vibration chamber is collided by the eccentric block, and the oil is stirred to carry out splash lubrication, prompting the grease to leak from both sides of the vibration shaft. Vibration wheel is generally inside and outside the cylindrical phase sleeve specification structure, the inner cylinder as a grease cavity, grease can be added to the internal structure, the two sides of the oil marks indicate the amount of oil. Both sides of the vibration wheel is fixed on the T-beam, the outer end is connected with the screw cap, and the screw cap is equipped with a skeleton seal. The eccentric block rotates with the vibration shaft and stirs the oil in the vibration chamber to produce splash lubrication. Important factors that jeopardize the leakage of the vibration chamber are: key structure and manufacturing quality, unscientific selection of skeleton seals, assembly errors, vaporization of the lubricant viscosity shrinkage, operation of the debris or accumulation of high-calorie food. Control methods are: improve the structure, select the appropriate and use the paired skeleton seal.

Vibratory roller control technology specification

1. When working, the roller drum needs to be started before running, and the gas turbine should be put to medium speed first, and then adjusted to fast.

2. When shifting gears and reversing, reduce the speed of the car when shifting gears.

3. Prohibit vibrating the roller on solid ground.

4. When damaging the soft roadbed project, it should be damaged 1~2 times firstly by it, not to vibrate, and then vibrate to damage.

5. When turning over, the vibration frequency should be consistent. For vibratory frequency adjustable vibratory roller, need to adjust the vibration frequency before running, prohibited in the case of no vibration to adjust the vibration frequency.

6. After the main clutch is disengaged, adjustments should be made to the shift clutch, start-up clutch and braking system.

7. When applying the steep slope left and right, it is not allowed to apply the rapid equipment. In the case of sharp curves, when the stranded vibratory roller turns over in the small turning circle, it is forbidden to apply the rapid transmission gear.

8. When traveling rapidly, the roller may not be combined with the vibrating gear.

9. When terminating, terminate the vibration, then place the reversing mechanism in the center position, put the gearbox in the neutral place, and pull the brake system lever on afterwards. The gas turbine is switched off after a few seconds of waiting for speed.
