Temperature rise in hydraulic cylinder

Temperature rise in hydraulic cylinder will shorten the using life of hydraulic cylinder.
Followed is the reason for temperature rise in hydraulic cylinder.
1. The volume of cylinder block is too small to eliminate heat efficiently. There is no cooling facility or it is too small and lead to temperature rise in hydraulic cylinder.
2. We often choose the oil supply system according to the oil flow speed. There will be a large amount redundant oil flow back to the valve in high voltage when working and it will cause
3. Temperature rise in hydraulic cylinder cause by the damage of unloading return circuit. Hydraulic cylinder could not unload when stop working. The all oil will flow under high voltage, and it will produce heat.
4. The pipe is the system may be too thin or too long, it will cause overmuch pressure loss .
5. The bad quality of spare parts will also cause temperature rise in hydraulic cylinder. Because of the poor precision, mechanical friction will produce luxuriant heat.
6. The fit clearance between fitting pieces is too small and may lead to temperature rise in hydraulic cylinder.
7. The high working pressure will cause temperature rise in hydraulic cylinder. The working pressure in hydraulic cylinder is higher than it needed. For the sealing device is too tight or damaged, we have no alternative but adjust the working pressure to a higher level.
8. The working condition is too high and lead the temperature rise in hydraulic cylinder.
9. Improper selection of hydraulic oil. The thick viscosity will cause more effective resistance. Otherwise, the thin viscosity will cause leakage. All of these will lead to temperature rise in hydraulic cylinder.
10. There has blocking in liquid inlet and make high speed flow, and then lead to temperature rise in hydraulic cylinder.
These ten are the main reason for temperature rise in hydraulic cylinder. Hope every custom can find reason from here and solve the problem of temperature rise in hydraulic cylinder.
