【摘要】：钻井往复泵是钻探机械设备的重要组成部分,被誉为钻机的心脏,良好的润滑是钻井往复泵正常工作的前提。本文对三缸单作用钻井泵的润滑系统进行了设计与分析。本文介绍了钻井往复泵各运动摩擦副有关摩擦、磨损和润滑的基本理论,根据钻井往复泵结构特点和功率流向图,将钻井往复泵的润滑系统总体设计为由传动端的压力油循环润滑系统和液力端的喷淋水循环润滑冷却系统两个子系统组成。设计了压力油循环润滑系统。推导了十字头滑道摩擦力做功计算公式,提出了一种十字头滑道摩擦副润滑油量的近似计算方法,并用积分法精确计算验证其可行性和可靠性。对压力油循环润滑系统中润滑油量、齿轮油泵、油箱、管路及其他部件进行了设计计算或选型。设计了喷淋水循环润滑冷却系统。将压力油循环润滑系统中机体油箱的冷却水管串联接入喷淋水循环润滑冷却系统,实现了结构的优化,建立了两个系统的联系。运用一维流体仿真软件Flowmaster对压力油循环润滑系统进行了稳态仿真,得到了润滑系统的各元件流量、流速和压力参数分布图,为验证润滑系统设计的合理性提供一定的参考价值。
[Abstract]:Drilling reciprocating pump is an important part of drilling machinery and is called the heart of drilling rig. Good lubrication is the premise of drilling reciprocating pump working normally.The lubrication system of three-cylinder single-acting drilling pump is designed and analyzed in this paper.This paper introduces the basic theory about friction, wear and lubrication of every movement friction pair of drilling reciprocating pump. According to the structure characteristic and power flow chart of drilling reciprocating pump,The overall design of lubrication system of drilling reciprocating pump is composed of two subsystems: the pressure oil circulation lubrication system at the transmission end and the spray water circulation lubrication and cooling system at the hydraulic end.The pressure oil circulating lubrication system is designed.The formula for calculating the friction force of the crosshead slide track is derived, and an approximate method for calculating the amount of lubricating oil in the friction pair of the cross head slide track is proposed. The feasibility and reliability of the formula are verified by the precise calculation of the integral method.The lubricating oil quantity, gear oil pump, oil tank, pipeline and other parts in the pressure oil circulating lubrication system are designed and calculated.The spray water cycle lubricating cooling system is designed.The cooling water pipe of the oil tank in the pressure oil circulating lubrication system is connected in series with the spray water circulation lubricating cooling system, which realizes the optimization of the structure and establishes the connection between the two systems.The steady state simulation of pressure oil circulation lubrication system is carried out by using one-dimensional fluid simulation software Flowmaster. The distribution diagrams of flow rate, flow velocity and pressure parameters of each component of the lubrication system are obtained, which provides a certain reference value for verifying the rationality of the lubrication system design.
