Recently, the power to introduce new technology - with pressure on the hole technology, has been used in our enterprise internal production workshop for many times. This technology can not stop, no reduction, stable operation of the production without affecting the case, the low pressure system for opening, thereby saving a lot of manpower and material resources. The electric hydraulic motor drive open hole machine transmission shaft, manual propulsion drive shaft connected to locate the center of the drill bit and open hole knife, connection for flange sealing connection, flange dribbling water or inert gas sealing interface, hole needs to be opened, first in open hole position, welding with short flange, supporting good ball valve or gate valve connection, fully open the valve can be opened hole machine with the valve connection hole, hole after the open hole drill and a knife back to the outside of the valve, close the valve, namely, the completion of opening. And removed when the holes of the circular iron sheet, by locating the center of the drill plates out of stock with, not only to achieve the opening, but also do not cause the removal of iron into the system to produce other effects.
Through this technology and has been used to solve the 4# variable system pipeline valve spool off, Hangtian gasifier to torch vent duct blockage, desulfurization system drop column temperature and gas cleaning tower, Sheung Shui poor blockage, new supercharger system grid and other problems. Each workshop from the initial sense of novelty, to the practical experience of the benefits of this technology, all applaud, think this is indeed a good technology to help produce the problem of solving the problem, it is worth the introduction.
