Embodiment 1
[0037] to combine figure 1 As shown, a mining dump truck cold start system,
[0038] The oil inlet of the engine 9 is connected to the oil inlet pipe II11, the other end of the oil inlet pipe II11 is connected to the oil-water separator 13, the oil inlet of the oil-water separator 13 is connected to the oil inlet pipe III14, and the other end of the oil inlet pipe III14 is connected to the first interface of the three-way joint II44 , the second interface of the tee joint II44 is connected to the oil inlet pipe I5, and the other end of the oil inlet pipe I5 is connected to the fuel tank 7; the oil return port of the engine 9 is connected to the oil return pipe II12, and the other end of the oil return pipe II12 is connected to the first interface of the tee joint I42 , the second interface of the three-way joint I42 is connected to the oil return pipe I6, and the other end of the oil return pipe I6 is connected to the fuel tank 7;
[0039] The oil inlet of the liquid fuel hea...
Embodiment 2
[0047] A kind of mining dump truck cold start method, on the basis of above-mentioned embodiment one, comprises the following steps:
[0048] Turn on the power supply of the whole machine, turn on the rocker switch 20, and the liquid fuel heater 30 starts to work;
[0049] The liquid fuel heater 30 begins to participate in the internal water circulation of the engine. If the coolant temperature does not reach 15°C at this time, the temperature control switch 17 will not work, and the red indicator light 19 will always be on;
[0050] After the temperature of the heated engine coolant reaches above 15°C, the temperature control switch 17 starts to work, so that the working circuit of the red indicator light 19 is disconnected, and the red indicator light 19 goes out at this time, reminding the driver that the engine can be started;
[0051] Close rocker switch 20 after engine starts.
[0052] combine image 3 As shown, the liquid fuel heater 30 is installed in the cold start ...

Abstract
The invention discloses a cold starting system and cold starting method for a mining dump vehicle and belongs to the technical field of mining machinery. An oil inlet of a heater is connected to an oil suction pipe III, and the oil suction pipe III is connected to a third joint of a three-way joint II; an oil return port of the heater is connected to an oil return pipe III, and the oil return pipeIII is connected to a third joint of the oil return pipe III; a water inlet of the heater is connected to a water outlet of a cooling pipeline in an engine cylinder sleeve through a water inlet pipeI, a stop valve I and a water inlet pipe II; and a water outlet of the heater is connected to a water inlet of the cooling pipeline in the engine cylinder sleeve through a water return pipe I, a stopvalve II and a water return pipe II. By increasing a temperature control switch and an indicating lamp specially for controlling a wiring harness, the heating temperature of a cooling liquid can be controlled precisely, the time is saved, and a near 100% low-temperature start success rate is achieved, so that the integral efficiency is the highest. The service lives of the engine and the mining dump vehicle are ensured, the attendance rate of the mining dump vehicle is improved and normal production is guaranteed.
Description
technical field [0001] The invention relates to the technical field of mining machinery, in particular to a cold start system and method for off-highway mining dump trucks. [0002] technical background [0003] Mining dump trucks have a wide range of applications, and the working environment is extremely harsh, generally in mines and plateaus. With the improvement and development of the overall technology of mining dump trucks, mining dump trucks continue to challenge various extreme climates, including extreme heat, dust, high humidity, and extreme cold. Therefore, according to engineering requirements, mining dump trucks need to work in cold areas such as high latitudes and plateaus all year round. Since most of the power sources of mining dump trucks are diesel engines, the starting performance of diesel engines has a great influence on the reliability and convenience of the whole vehicle. Performance, durability, and fuel economy all have a great influence. Unreliable e...
