Has been committed to its HMB hydraulic attachments & excavator attachments.
we all know that can not be caught fire because there are many kinds of excavators, some time ago we excavator accessories manufacturers published titled 'excavator parts winter start difficult? Is not necessarily the fault of the battery of! ', solve the generator fault lead to start the difficulty of this problem, today small make up and other reasons to give you for detail.
some of the reasons for out of excavator car, the car won't lead to hit most of the reasons is the cause of the circuit. So how to determine is circuit causes not car?
1。 Check excavator parts of relay fuse box
then began to check the starter relay and fuse box, check whether the joint is loose open relay box, and then open the fuse box is starting circuit the fuse is burnt out.
of course, the excavator attachments start motor or generator fault can also lead to out of a car, among them, the generator failure can lead to a generator to power generation, battery power can't be added, leading to start the motor speed is low or not.
2。 Check the battery pile head
check circuit can begin from fountainhead, first check the battery of excavator parts pile head, clean up the storage battery pile head, again the pile head screw tight tight, all because of a lot of car battery pile head is loose, lead to poor contact, the voltage is not enough. Conditional owners can use the multimeter voltage test battery voltage.
if no fault in the battery the next step is to check the line, down the battery line to check it again, observe whether there is a broken line or connector is loose.
2, there is something wrong with the oil
if turned very powerful start key can hear the start motor, and the engine is not the voice of the abnormal mechanical friction, so the excavator accessories manufacturers can be judged to be the cause of the oil. Direct injection of car oil check easier than ems, for some of the electronically controlled high pressure common rail engine check is more complicated. Generally available from the following steps to check.
1, the engine exhaust air
the reasons of too much water in the exclusion of diesel, if also can't in the car next to check whether diesel mixed with air, first find the location of the excavator parts hand pump, different brand launched a machinist pump installation position is different, have a plenty of installed near the diesel pump, have a plenty of plus electronic pump so you don't need to manually exhaust air.
currently sold in most of the excavator parts above the hand pump installed in the oil-water separator, deflated bolt next to let go of screw pump, according to the hand pump with the hand, until the deflated bolt out all diesel, then deflated bolt tightening completes the exhaust air work.
2。 Oil-water separator drain
in determining the tank has sufficient ignition of diesel, the next step is to oil-water separator, excavator accessories manufacturers found many owners do not every day to the habit of oil-water separator drain, if just use the product quality is not high, they may be due to diesel too much water to be launched.
oil-water separator generally have red buoy, the buoy density between diesel water, so will float on the surface of the water and at the bottom of the diesel, when observing oil-water separator buoys in the middle, excavator attachments manufacturer to remind you to timely unscrewed the oil-water separator at the bottom of the drain bolt draining water, this is so for each oil-water separator.
3。 Check whether there is enough fuel
first to check whether there is oil tank, incredible guys might think this step, but in fact, because there was no oil tank and out of the car users.
oil good car can be observed through the oil tank of oil, but at this time is the best way to excavator parts fuel tank oil level gauge or open the cap to check whether there is enough fuel tank, oil meter, after all, also will be failure.
three, mechanical failure
if the inspection found that the circuit and oil are no problem, then it is possible that the engine produces mechanical failure.
general diesel engine mechanical failure probability is low, but in the event of mechanical failure is faced to overhaul engine, a drawing cylinder excavator accessories machinery common faults and tile burning, cylinder, etc. , in general engine mechanical problems are precursors, such as engine suddenly unable to running in normal operation, or the total smoke and have a sound operating and so on.
excavator parts small make up the dig spare no effort to service the vast number of friends, is to want to dig for the friends to solve practical problems. The last small make up remind you troubleshoot circuit when it is important to note that accidentally wrong easily cause big loss! Suggest beginning ability is not strong dig friends go directly to the garage.
