Main performance characteristics of XCMG GR215-LNG grader (two)

The main performance characteristics of XCMG GR215-LNG grader include economy, power, safety, reliability and operation comfort.

Security

The biggest difference between the GR215 - LNG grader and the diesel engine grader is the use of LNG fuel and LNG compression cylinders, so its safety performance depends directly on the reliability of the LNG fuel and LNG cylinders. LNG as a liquid fuel and the gas density is very low, about 1/2 of the air, if there is leakage will open to the sky flying, even if it is not easy to fire in a confined space, because the LNG ignition and explosion limit are very high, so the security of LNG is guaranteed.

GR215-LNG grader LNG cylinder adopts special materials to meet manufacturing requirements of the national standard, impact resistance and high strength, between the outer wall and liner using vacuum treatment, and in accordance with the national standard of vibration, fire and drop performance test, to ensure the safety of gas cylinders can.

reliability

The working device adopts a friction type turbine box and a rotary support, and a clutch structure is composed of a pressing plate, an adjusting shim, a friction plate set, a wear-resistant pad and a locking nut between the worm wheel and the gear shaft. The internal friction force of the clutch is determined by the pressure applied to the platen, and by adjusting the number of shims, the platen is subjected to different stresses. The impact force on the blade through a rotary ring and pinion gear and gear shaft after the transfer to the clutch friction plate group, when the external impact force is greater than the preset force when the clutch friction plate group, clutch slip, and drive the small slip, thereby reducing the impact of worm gear. When an external effect on the blade impact force is too large, the friction piece group of worm gear box clutch sliding teeth drive wheel slip, turn, thus reducing the impact of gear box, to avoid the premature damage of related parts. Maintenance free slewing bearing supports the hydraulic upper limit pressure of multi way valve, which can realize 360 degree slewing of working device.
