| Abstract: | This paper studies the steadystate motion law of triplex drilling pump with friction considered. It used the numerical evaluation of gradual approximation to solve the interdepence problem between friction force and torgue of friction and the law of motion of the pump. Taking 3NB—1000 friplex drilling pump as an example, the paper also discuses and analyes the speed fluctuation and torgue fluctuation of the crank in all kinds of working conditions, points out that the change of certain favourable working condition indicates the change of running performance of the pump. It proposes that torque fluctuation coefficient should be regarded as the main basis for evaluatiog the running smoothness of the pump. |
