The system about the eddy current brake in drilling rig is very important and friable component. The temperature will arise with the winch lift the heave object and break, which will affect the winch. The conventional drilling rigs are cooled by air blast or water circulation, which always can’t content the request of drilling rig winch brake system. For this situation, I am to design and manufacture the forced heat-dispersing unit for ZJ70/4500DZ drilling rig winch. This device unified the formerly forced-air cooling and water cooling characteristic, and what’s more, it consists of air cooler, water tank, water pump valves, manifold and instruments. It has lots of advantages, for example: structure compact, easy installation and maintenance and so on. The article in the bases of analyses the ZJ70 drilling rig winch system characteristic and the theory of the formerly heat-dispersing, to introduced the approach of design and composition design… |
