| Analysis of domestic product quality seals | 20 years, through the joint efforts of domestic scientific research and technical personnel, the establishment of a complete range of integration with ISO/TC131/SC7 seal Jianan Zhuang national standards body cavity. Also established with various international standards seals seals size series, sealing performance and appearance quality seals, seal packing, storage, transportation and other seals national standards. Thus, to facilitate the construction machinery and other medium and high pressure hydraulic mechanical seals in seal systems design and selection. However, there are still many shortcomings in practice there is. The main reason is too weak industrial base, raw materials, quality and variety is not satisfactory, management of non-standard and so on. Especially in gas-liquid pressure cylinder gap, hydraulic pumps, hydraulic motor and gearbox oil seals and hydraulic rotary cylinder reciprocating dynamic sealing of the product quality is the worst. ZL50C loader drive axle for the wheel side seal life, I have done a comparative test installed by a domestic unit with assistant lip developed within the framework oil seal, installed by the road test after only 50km began to leak, and assessment also installed a foreign company BABSL oil seal, use the last 3 years not leak. Another example: construction machinery components, hydraulic cylinder seals of quality, to meet the 5000 standards abroad for hours without leakage, and the general life of seals made for 1 / 10, some even less than 100 hours of work.
