Proper use of Polyurethane seal,should pay attention to the following points:
1. Improve lubrication quality, control oil pressure, temperature and flow, and strengthen oil filtering. 2. Use fuel and
lubricants that meet the requirements. 3. In order to control the temperature state of the diesel generator set, it is not
suitable to work under the condition of overcooling or overheating. In cold weather, the diesel engine should be preheated before
starting, and the crankshaft should be turned by hand to allow the oil to enter the friction surface. 4. The surface quality of
the piston rod and journal should be strictly guaranteed. 5. The piston rod clearance should be appropriate. If the generator set
is too large, it will cause an impact, and if the generator set is too small, the lubricity will deteriorate.
