Bridge crane hydraulic oil pump coupling diagnostic method innovation

Bridge crane hydraulic oil pump coupling 2020 - diagnosis method innovation 11 - Y. s. ho (13 Suzhou modern engineering department) Engineering department actively carry out technical innovation, equipment reform, such as innovation activities, efforts to improve employees' skills level, stimulate employee creativity. The hydraulic oil pump coupling (bridge crane group innovation Note 1) Rapid diagnostic methods. The plan put forward by team members after xue-yong liu and his colleagues studied together, namely in the oil pump bracket to increase a window ( See image below) Intuitive, and can be used to confirm the parts of wear degree, than the original by coupling is audible only to identify the method greatly improves the accuracy of fault. Engineering department immediately on the 23 and 27 bridge crane for verification, the results show that the coupling state caused by the original 2 hours sharply reduced to 2 minutes. Coupling of the maintenance by the original 6 2 days to 3 1 day. A new diagnostic scheme significantly improves the maintenance efficiency, so as to raise the utilization rate of equipment. Engineering department will follow-up to increase the capacity for independent innovation as the core of the department, in order to improve the efficiency, improve quality, innovative technology, safe production as the guidance, continue to extract synergies, contribute to technological progress contribute to promote the company. Note 1: the hydraulic pump is one of an important part of a bridge crane operation, it is the heart of the bridge crane hydraulic system, is responsible for converting mechanical energy to the liquid pressure can. And coupling is connected motor and oil pump in order to transfer the kinetic energy, avoid rigid motion of the flexible components necessary.
