Domestic roots pump according to the current standards are still about 30% of substandard products, if compared with the international advanced level, the overall performance gap greater. Mainly manifested in: serious serious shaft seal, domestic shaft seal can not withstand long-term operation, oil leakage is more common; vibration, noise. Some products are poorly balanced, and some gears and bearings are not accurate enough. According to the industry standard, the zero-flow compression ratio and the maximum allowable pressure drop of some products can not meet the standard requirements. Some enterprises are outdated in production technology and equipment and can not guarantee that parts The machining accuracy and assembly accuracy. Due to the above problems, the performance of the Roots pump is not reliable and the failure rate is high. Some pumps will be repaired a few months of operation, with the German company LH Roots pump operation for several years without a huge contrast to repair.
