2. Reduce wear and tear of dynamic seals
Most of the dynamic seals are precisely designed. If the dynamic seals are processed properly, installed correctly and used reasonably, they can be guaranteed to work relatively leak-free for a long time.From a design perspective, designers can take the following measures to extend the life of dynamic seals:
(1) Eliminate side loads on piston rod and drive shaft seals;
(2) Protect the piston rod with dust ring, shield and rubber sleeve to prevent abrasions, dust and other impurities from entering;
(3) Design and select appropriate filter devices and easy-to-clean oil tanks to prevent dust accumulation in the oil;
(4) Make the speed of the piston rod and shaft as low as possible.
3. Control oil temperature to prevent deterioration of seals
Premature deterioration of seals may be caused by a variety of factors, an important factor is that the oil temperature is too high.The life of the seals will be halved every 10 degrees of temperature rise, so the efficient hydraulic system or the forced cooling device should be rationally designed to keep the optimal oil temperature below 65 degrees, engineering machinery should not exceed 80 degrees, another factor may be the compatibility of the oil used with the sealing material, the type and material of the hydraulic oil and seals should be selected according to the instructions for use or relevant manuals.Quality to solve compatibility problems and prolong the service life of seals.
