Now construction machinery hydraulic parts using mechanical products a lot, whether it is splitting machine efficiency, or hydraulic hammers and other hydraulic system mainly depends on the volumetric efficiency of the pump when the volumetric efficiency drops to 72% when you need to carry out routine maintenance , replace the bearings and seals of aging, to replace or repair beyond the friction with the gap deputy, its performance is restored. Let's maintenance methods to introduce next.
The main way to prevent oil pollution are:
When various hydraulic fittings assembly, prohibit the use of fabrics with fibers (such as cotton) wipe;
Seal must be reliable, prohibit the use of non-oil seals and hoses;
Before installation of the pipes, castings, etc. to be thoroughly cleaned, hydraulic fittings manufacturers system after the completion of the assembly should be thoroughly cleaned;
Sealed tank to be reasonable, to be set up through the atmosphere at the air filter;
Transmission part of the bearing at the factory filled with the right amount of grease (the 1st calcium - Kea), the instrument during continuous work, once every six months should bear grease, fill the bearing space accounts for about a third of .
Instruments often of use, natural wear and tear is normal. Instrument after one year, if found motors, compressors abnormal noise; transmission parts bearing wear, loose or cracked belts, hydraulic fittings failure and other failures, should find manufacturers handle.
hydraulic tube fittings mentioned above maintenance and protection programs.
