Brief Introduction：
We try to use the drive equipment to its full capability according to the different situation when we are designing programs.
Dredge pump system is designed with the function of stroke setting. With set stroke, dredge pump system could avoid the pressure of pump becoming too high during the bulge test or normal drilling. Furthermore, it will help to realize the replacement of pump during cementing.
We specially used the energy-loss brake as the auxiliary brake in the AC-driving program. Because we try to realize the high-speed trip, ensure the frequency converter under normal condition as well as save space of drilling platform by this method.
Our brake power could reach 3000kw.
