F. The channel plate course of action isn’t slick F. The most extreme misalignment filter press troubleshooting of the channel plate plan isn’t more than 5mm, any other way it will release fluid and the channel plate ought to be organized flawlessly.
4、No progress ahead or in reverse A、Insufficient oil level A、When the oil level can’t be shown by the oil marker, it implies that it ought to be loaded up with oil to guarantee typical activity of the siphon station.
B, high strain or low tension help valve stuck or harmed B, destroy and clean, in the event that actually would not work be able to appropriately might be the point at which the alleviation valve is harmed, to supplant.
C, cylinder siphon harm C, the oil circuit isn’t smooth or would not supply be able to oil, can be decided as a cylinder siphon harm, cleaning, actually can not work as expected then to supplant.
D, engine guiding isn’t right D, see whether the engine fan is turned clockwise, in any case the engine is decided to be associated with the converse, any two lines at the engine bay end can be exchanged.
E, electromagnetic turning around valve no activity E, clean the switching valve or supplant.
5, after the tension would not stop A, electric contact be able to pressure table change esteem is excessively high A, utilization a screwdriver to change the electric contact pressure table on the change screw, as far as possible worth is changed down.
B, electric contact pressure table awful B, when the tension table pointer swing isn’t touchy or pointer can not get back to zero ought to be supplanted when the strain table.
C, the help valve is changed excessively low C, utilize a screwdriver to change the change screw on the electric contact pressure check, as far as possible worth to 5 Mpa.
6、No tension holding A, pressure-holding pipeline spillage A, see whether the pipeline is harmed, supplant the pipeline in like manner or fix the association nut.
B. Pressure-holding valve is stuck or harmed B. Clean the strain holding valve and supplant it in the event that it actually doesn’t work.
C、Safety valve is stuck or breaking down C、Clean the security valve, actually can not attempt to supplant.
