Underground loader, also known as mine loader or explosion-proof loader, is generally used in places such as mine tunnel internal mineral transportation, narrow roadway and tunnel construction. When the diesel engine of the loader is running, the speed will change periodically from high to low within a certain range, which is called traveling block. Sometimes traveling occurs when idling, or traveling occurs when the accelerator pedal is at a certain position, or traveling occurs under a certain load. The traveling block of the loader is essentially a breakdown of the normal speed regulation function of the diesel engine. Generally, the resistance of the moving parts in the governor or fuel injection pump components is too large, and the sensitivity of the governor is reduced, leading to traveling block; Of course, if the fitting clearance of the internal parts of the governor or fuel injection pump is too large, which causes the change of fuel supply to lag behind, it will also cause the traveling block of the loader. If the loader travels, what should we pay attention to?

检查装载机的低压油路，因为油路出现阻塞、供油不畅，会破坏供油连续性，供油油路进气，喷油器雾化不良或出现卡死，使得各个缸工作不均匀便会导致游车。

Check the low pressure oil circuit of the loader. Because the oil circuit is blocked and the oil supply is not smooth, the continuity of oil supply will be damaged. The oil supply oil circuit will intake air, the atomization of the fuel injector is poor or stuck, and uneven operation of each cylinder will lead to traveling block.

大家在检查井下装载机游车故障的时候，要仔细检查油路是否存在故障；如果油路没有故障，再去检修喷油泵的调速器、校验喷油泵。

When checking the traveling block fault of the underground loader, you should carefully check whether there is any fault in the oil circuit; If there is no fault in the oil circuit, repair the governor of the fuel injection pump and calibrate the fuel injection pump.

喷油器低速工作不良的现象，主要是因为喷油器磨损或制造质量差，从而导致低速的时候不雾化或在滴油，而在中高速的时候工作可以正常；喷油泵怠速供油不足，将怠速油量调高之后，游车现象就会消失；怠速限位螺钉调整不当，造成怠速游车，要及时调整怠速限位螺钉。

The poor operation of the fuel injector at low speed is mainly due to the wear or poor manufacturing quality of the fuel injector, which results in no atomization or fuel dripping at low speed, but normal operation at medium high speed; The idle fuel supply of the fuel injection pump is insufficient. After the idle fuel volume is increased, the traveling block phenomenon will disappear; If the idle limit screw is not adjusted properly, causing idle traveling block, adjust the idle limit screw in time.
