prevent leaking fuel pump of the technical measures

     strengthen the fuel supply system maintenance, the use of sedimentation and filtration, after full diesel fuel tank regularly released, sedimentation Cup and thickness and filter impurities in the water, and cleaning them, so as to reduce the wear-and precision.

     correct fuel pump assembly. Assembly, the parts must be thoroughly cleaned, to prevent impurities in the adhesion with the surface parts. Dismounting plunger pack filling valve counterpart, it is necessary to remove the pair, installation and replacement. Plunger should not arbitrarily selected and, if necessary, do a good job marking, so as to avoid confusion, resulting in a dual meet plunger gap too large oil spills. Do not pay attention to the loss and leakage loaded plunger positioning screw sets the copper washers. Technical manuals in accordance with the provisions of torque (60 N.m ~ 70N.m) Tightening the tight oil valve seat. Not a hard twist, it is non-standard installation governor caused. Return OUR request author personally inspect the installation from start to finish again. After listening to the users and analysis, I am skeptical. I personally governor is installed, the installation size and flexibility are good. However, it will not able to say specific reasons. Open governor inspection, all normal, pulling teeth-examination, felt that they were two-cylinder plunger sensitivity there Lag card phenomenon, but it is not very obvious. Removing a plunger, piston kit found deformed copper pads, as if shallow plate-shaped, with the body-checked and found that a little depression. Cause is the cause of the malfunction: users found that the pipeline after the oil spill in the pipeline forced pull tight to prevent the nut before the event, and pull force to bear on tight oil valve, the pressure over copper pads affordability deformed with a plunger sets of deformation, Plunger activities that obstructed the sky above fault. Approach:

     inspection cylinder plunger which is a failure, a release valve tight oil blocks, with hammer blow to adjust gear to restore vertical plunger, then slowly and gradually pull tight, the pull of the tight control in allowing dirt range. Approach:

     gasket with a pair of scissors Qiaoqi part re-installation, the pull of the tight control in a certain range, the machine testing, fault solved.
