【摘要】：可靠的軸向力平衡裝置是高壓多級(jí)離心泵實(shí)現(xiàn)長(zhǎng)期安全運(yùn)行的重要機(jī)構(gòu)。針對(duì)高壓離心泵對(duì)運(yùn)行可靠性和使用壽命的要求,創(chuàng)新設(shè)計(jì)了一種壓力室平衡裝置自動(dòng)平衡高壓離心泵的軸向力。在流力基本理論指導(dǎo)下基于試驗(yàn)流體力學(xué)方法研究了3個(gè)阻尼孔直徑對(duì)整機(jī)效率、流量、壓力、功率的影響。針對(duì)D25-30×5多級(jí)離心泵,通過(guò)試驗(yàn)確定了在阻尼孔直徑為ф4~6mm時(shí),得到了較高的整機(jī)效率η=0.701~0.802,效率比原平衡盤(pán)結(jié)構(gòu)最大提高18%。機(jī)組運(yùn)行振動(dòng)小、噪聲低,能長(zhǎng)時(shí)間平穩(wěn)可靠工作。
[Abstract]:Reliable axial force balancing device is an important mechanism for long-term safe operation of high-pressure multistage centrifugal pump. According to the requirements of high pressure centrifugal pump for operation reliability and service life, a pressure chamber balancing device is designed to automatically balance the axial force of high pressure centrifugal pump. Based on the experimental hydrodynamics method, the effects of three damping hole diameters on the efficiency, flow rate, pressure and power of the machine are studied under the guidance of the basic fluid force theory. For D25-30 脳 5 multistage centrifugal pump, when the diameter of damping hole is 4~6mm, a higher efficiency 畏 _ (0.701) ~ (0.802) is obtained, and the maximum efficiency is 18% higher than that of the original balance disk structure. The operating vibration of the unit is small, the noise is low, and the unit can work steadily and reliably for a long time.
