After working for a few years, the loader may gradually encounter various loader problems. The common one should not be able to hit the digger. Many small loaders do their work, and they have to wait for the user's phone or the user to come to work every day. At this time, if the digger can't catch the car, I don't know how worried.
What should I do if the loader does not catch fire
In this article, I will tell you why you ca n’t get in a car, and how to troubleshoot problems.
View battery head
Check the circuit can start from the source, first check the battery pile head, clean the battery pile head, and then tighten the screw of the pile head. Many vehicles are due to the loose battery pile head, resulting in poor contact and insufficient voltage. A qualified owner can measure the battery voltage with a multimeter voltage file.
If the battery is not defective, the next step is to check the line. Follow the line of the battery to check whether the line is broken or the connector is loose.
View relay box fuse box
Next, start to check the initiating relay and fuse box, open the relay box to see if the connector is loose, and then open the fuse box to see if the initiating circuit fuse is burnt out.
Of course, the fault of the motor or the generator can also cause the car to be hit. Among them, the fault of the generator will cause the generator to fail to generate electricity normally, the battery power cannot be replenished, and then cause the speed of the motor to start low or not rotate.
Oil road
In addition to the cause of the circuit, the oil circuit is also a common cause of not being able to get into the car. So, how can I tell if the oil circuit is wrong and can't get into the car?
If you can hear the powerful rotation of the initiating motor when you turn on the key, and there is no abnormal mechanical conflict sound from the initiating machine, you can roughly determine the cause of the oil circuit. The inspection of the oil circuit of the direct injection vehicle is simpler than the circuit, and it is more complicated to check the initiators of some electronically controlled high-voltage common rail. You can generally view it from the following steps.
Oil-water separator drain
After confirming that there is enough diesel in the fuel tank, the next step is the oil-water separator. In fact, many owners do not have the habit of draining the oil-water separator every day. If the quality of the oil used is not high, it may be due to diesel There is too much water to initiate.
The oil-water separator generally has a red buoy. The density of this buoy is between the water of the diesel and it will float on the water and be at the point of diesel. When the buoy of the oil-water separator is in the center, the bottom of the oil-water separator should be unscrewed in time. The drain bolt drains the water, which should be done for every oil-water separator.
Circuit
There are many reasons why the loader can't hit the car, and the reasons that can't hit the car most are the reasons for the circuit. So how do you tell if the circuit is the reason that you can't catch the car?
The fault of the circuit leads to the inability to hit the car. The main reason is that the incineration switch is turned on and there is no response or the motor speed is too low to feel the powerless feeling. If the two phenomena cannot be caught, it can be roughly determined that there is something wrong with the initiating circuit. So, how can we troubleshoot it?
Check if there is enough fuel
First check if there is oil in the fuel tank, maybe everyone will think this step is too incredible, but in fact there are not many users who can't get a car because the fuel tank is out of fuel.
A car with a good fuel gauge can use the fuel gauge to investigate the amount of fuel in the fuel tank, but at this time it is best to still check the fuel tank through the fuel level gauge or open the fuel tank cap to see if there is enough fuel in the fuel tank. .
Mechanical problems
If after inspection, there is no problem with the circuit and the oil circuit, then there may be a mechanical problem caused by the engine.
Generally, the probability of mechanical problems in diesel engines is relatively low, but once the mechanical problems occur, it is necessary to overhaul the engine. Common engine problems include pulling cylinders, burning tiles, ramming, etc. In general, engine problems Mechanical problems are all harbingers, such as the sudden failure of the engine to work in normal operations, or the total smoke and the abnormal sound of the work process.
Engine exhaust air
After excluding the cause of excessive water in diesel, if you still ca n’t get on the vehicle, the next step is to check whether the diesel is mixed with air. The first thing is to find the orientation of the hand pump. The diesel pump is nearby, and some are equipped with an electronic oil pump so there is no need to manually exhaust the air.
Most of the loader hand oil pump devices currently on sale are above the oil-water separator. Loosen the bleed bolt next to the hand oil pump, and press the hand oil pump by hand until the bleed bolt comes out of diesel. Then tighten the bleed bolt. Air exhausting work.
Under normal circumstances, after checking the circuit and the oil circuit, you can drive. If this time is still not, you should consider the mechanical reasons.
