Front end hydraulic cylinder common problem:
First, the fuel tank leakage or leakage
1. serious overload. Due to the internal sealing lip cylinder cannot withstand excessive pressure and leakage.
2. Serious partial load
3. The top of the cylinder is not installed vertically, the user caused by improper operation of the upper bracket deformation or displacement.
4. User improper operation caused by cylinder deformation. Cabin in the lifting or lowering work violently shaking or overturning, so that the cylinder was a strong impact, causing the cylinder deformation or bending
5. Barrel strain.
6. due to unreasonable design, so that the top of the cylinder work, and the carriage interference caused by the cylinder strain
7. Cylinder trunnion and bracket hole with the gap is too large (2 mm) caused by the top cylinder partial load caused by bar strain.
8. Cylinder head nut loose caused by the top cylinder cover scratches the barrel caused by strain.
Second, chaos cylinder (cylinder is not to lift)
1. Improper operation caused by the user cylinder or cylinder deformation (overturn, cylinder by external impact, the use of emergency brake unloading, etc.)
2. the cylinder bore internal fine particles produced after the arrest of the guide ring, causing chaos cylinder.
Third, the cylinder rod out of line or stuck
1. missing (welding) limit plate limit valve failure.
2. Limit valve internal failure caused by cylinder out of line.
3. To improve the trip, the user adjusts the limit valve stem without permission, causing the limit valve failure caused by dislocation of the cylinder rod or stuck.
4. Limit valve stem cannot return caused by fuel tank stuck.
Limit valve is to control the normal use of key components of the cylinder, once the failure, most likely to cause very serious consequences, can be summarized as: small parts, major faults. Please pay attention to the installation of parts inspection, and guide the user to use the proper maintenance.
