【摘要】：鉆井往復(fù)泵是鉆探機械設(shè)備的重要組成部分,被譽為鉆機的心臟,良好的潤滑是鉆井往復(fù)泵正常工作的前提。本文對三缸單作用鉆井泵的潤滑系統(tǒng)進行了設(shè)計與分析。 本文介紹了鉆井往復(fù)泵各運動摩擦副有關(guān)摩擦、磨損和潤滑的基本理論,根據(jù)鉆井往復(fù)泵結(jié)構(gòu)特點和功率流向圖,將鉆井往復(fù)泵的潤滑系統(tǒng)總體設(shè)計為由傳動端的壓力油循環(huán)潤滑系統(tǒng)和液力端的噴淋水循環(huán)潤滑冷卻系統(tǒng)兩個子系統(tǒng)組成。 設(shè)計了壓力油循環(huán)潤滑系統(tǒng)。推導(dǎo)了十字頭滑道摩擦力做功計算公式,提出了一種十字頭滑道摩擦副潤滑油量的近似計算方法,并用積分法精確計算驗證其可行性和可靠性。對壓力油循環(huán)潤滑系統(tǒng)中潤滑油量、齒輪油泵、油箱、管路及其他部件進行了設(shè)計計算或選型。 設(shè)計了噴淋水循環(huán)潤滑冷卻系統(tǒng)。將壓力油循環(huán)潤滑系統(tǒng)中機體油箱的冷卻水管串聯(lián)接入噴淋水循環(huán)潤滑冷卻系統(tǒng),實現(xiàn)了結(jié)構(gòu)的優(yōu)化,建立了兩個系統(tǒng)的聯(lián)系。 運用一維流體仿真軟件Flowmaster對壓力油循環(huán)潤滑系統(tǒng)進行了穩(wěn)態(tài)仿真,得到了潤滑系統(tǒng)的各元件流量、流速和壓力參數(shù)分布圖,為驗證潤滑系統(tǒng)設(shè)計的合理性提供一定的參考價值。
[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.
