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?
檢查裝載機(jī)的低壓油路,因?yàn)橛吐烦霈F(xiàn)阻塞、供油不暢,會(huì)破壞供油連續(xù)性,供油油路進(jìn)氣,噴油器霧化不良或出現(xiàn)卡死,使得各個(gè)缸工作不均勻便會(huì)導(dǎo)致游車。
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.
大家在檢查井下裝載機(jī)游車故障的時(shí)候,要仔細(xì)檢查油路是否存在故障;如果油路沒(méi)有故障,再去檢修噴油泵的調(diào)速器、校驗(yàn)噴油泵。
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.
噴油器低速工作不良的現(xiàn)象,主要是因?yàn)閲娪推髂p或制造質(zhì)量差,從而導(dǎo)致低速的時(shí)候不霧化或在滴油,而在中高速的時(shí)候工作可以正常;噴油泵怠速供油不足,將怠速油量調(diào)高之后,游車現(xiàn)象就會(huì)消失;怠速限位螺釘調(diào)整不當(dāng),造成怠速游車,要及時(shí)調(diào)整怠速限位螺釘。
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.
