Hong-jun ren bulb turbine units outside the guide vane bearing removal tool

Hong-jun ren bulb turbine units outside the guide vane bearing removal tool - 2018 11 - 11 investment group in qinghai sanjiang hydropower companies' my tooling I design the tools I transform 'excellent results show 1 results design concept of bulb turbine units due to special equipment layout, run after a period of time outside the guide vane bearings with seals wear will appear different degree of leakage or bearing jammed phenomenon, bearing is not easy to remove, destructive is dismantled need to purchase new bearing equipment replacement, is bound to cause the cost of production increases. In order to solve the problem of outside the guide vane bearings remove Huang Feng hydropower station, the brothers with the same type unit power plant communication for many times, and access to large amounts of information on the Internet. Sanjiang hydropower company decided to design a set of Huang Feng hydropower station outside the guide vane bearings remove the special tool, since this design need to be customized special hydraulic cylinder, so entrust a specialized manufacturer for production. This special tools must be based on the guide vane of Huang Feng hydropower station outside bearing size, related tools main parts for the piston cylinder, piston rod, seal, adjusting bolt, guide bar, positioning block, fixed bolts, high pressure oil interface, etc. 2 results usage since March 2018 results to complete, remove the guide vane has achievements outside bearing 5, remove the bearing caused no damage in the process. Meet the requirements of the using effect. 3 results economic benefits ( 1) Save equipment purchase cost: about 3. 90000 yuan the equipment built in the sanjiang hydropower company personnel, by host supplier Toshiba hydropower equipment (Huang Feng hydropower station Hangzhou) Co. , LTD. , provide free of charge. ( 2) Now save bearing equipment procurement cost: 800000 yuan outside a guide vane bearing purchasing about $10000, 16 sets Huang Feng hydropower station is a unit outside the guide vane bearings, a total of 5 units, a total of 80 units outside the guide vane bearings, save procurement costs about 800000 yuan. ( 3) Reduce artificial cost about: 1. RMB 20000 / bearing destructive to dismantle one bearing and back pack 6 people need eight days. The tooling to dismantle and back pack 6 people need 3 days, an average of 1 labor calculated at 400 yuan/day, repair a bearings reduce artificial cost 1. 20000 yuan, improve work efficiency, shorten the maintenance time, reduce the labor cost, improve the equipment running time, increasing the benefit. 4 achievement promotion value outside the tool remove guide vane bearing effect is good, can guarantee the guide vane to receive strength evenly in the outer bearing dismantled bearing outer ring, synchronize the bearing to exit. The equipment hydraulic drive it economizes manpower, and make the maintenance period shorten, and reduce the damage rate of disassembled bearing, reduce the production cost. The same type power station unit can draw lessons from. Team introduce hong-jun ren bulb tubular unit outside the guide vane bearing removal tool design renovation team is made up of sanjiang hydropower company hong-jun ren, xiao-chun sun two people. Members: hong-jun ren: male, han ethnic group, 41-year-old, sichuan university network education college of electrical engineering and automation, bachelor degree, senior engineer. Now the sanjiang hydropower company deputy general manager, engaged in tooling design to guide the work in the team. Xiao-chun sun: male, han ethnic group, a 40-year-old, xian university of science and technology and my major is thermal energy and power engineering bachelor's degree, senior engineer. Now the ministry of mechanical and electrical in team engaged in equipment design and professional manufacturer of technical communication, etc.
