1, glue repair glue leakage method. Oil tanks, water tanks, tubing, and water pipes may cause small leaks due to cracks or blisters, pores, etc., and can be applied to the clean damaged parts with adhesive glue. 2, add pad governance leakage method. Leakage at the leak-proof gasket of diesel engine oil pipe joints can be added on both sides of the leak-proof gasket with a layer of double-sided smooth thin plastic mats, which can be leak-proof when tightened tightly; When many paper pads of diesel engine bottom case, cylinder head, gear chamber cover, crankcase back cover etc. leak, if the paper pad is in good condition and the joint surface is clean, apply a layer of butter on both sides of the paper pad and tighten the bolts. Leakproof; such as a new paper pad, the new paper pad in diesel soak for 10 minutes, remove and wipe, wipe a layer of butter on the joint surface and then install. 4, paint film leakage method. If the diesel engine tank, water tank, crankcase, etc. are leaking, the paint film can be soaked in alcohol and the paint film can be applied to the clean joint. 5, anaerobic glue leakage method. When leakage occurs at the vent bolts, stud bolts, etc. on the diesel engine, anaerobic adhesive can be applied to the threads or screw holes of the cleaned bolts, which can quickly solidify to form a thin film and fill the gaps of parts; this method is used for diesel engine high voltage Pipe joints at the thread leakage better. 6, liquid sealant leakage method. When interfacial leakage and destructive leakage due to solid gasket defects occur on the diesel engine, apply a liquid sealant to the cleaned solid gasket joint surface to form a uniform, stable and continuously adhered peelable film gasket after curing. , can prevent leakage. 7, the size of the glue recovery method. When the shaft and bushing of a diesel engine, bearings and housings, valves and valves, self-tightening oil seals, packings, etc., are leaking, the size recovery glue can be used to smear the worn parts of cleaned fittings, and the abrasion resistance and mechanical strength can be formed after curing. The higher film layers are then machined to restore the part's geometry and fit accuracy to resolve leaks.
