Abstract

The issues of studying the operating parameters of the elements of lubrication systems for high-speed internal combustion engines preceded the creation of the stand. The engine lubrication system D-246.4 was chosen as a prototype. With the help of this stand it became possible to study the lubrication system for the following characteristics: change the performance of the engine oil pump D-246.4, change and control the engine oil temperature, control the pressure drop on the oil filter, control the engine oil flow, throttle oil at the inlet to the oil pump and on the conditional supply line to the friction units, measuring the vacuum of the system on the suction of the oil pump and recording the parameters of the pulsation of the oil pressure generated by the oil pump. To build mathematical models of the components in the lubrication systems of marine internal combustion engines there is a need to determine their operating parameters. In real operating conditions, such measurements cannot be obtained due to the lack of the necessary test equipment (TE) and the possibility of its installation. The authors describe in detail all the components of the stand for studying the parameters of the elements of lubrication systems of high-speed internal combustion engines, their technical characteristics, describes the diagnostic complex, which recorded the results of research, the results of measuring engine oil pressure pulsation. The stand is used to study the operating parameters of the oil pump and filter used for water. Signals are registered using the Autoscanner diagnostic system. The diagnostic complex is a 64-channel oscilloscope that is connected to a personal computer. This stand for studying the operating parameters of the elements of the lubrication system provides sufficient opportunities to simulate the operating conditions of the elements of the supply and purification of oil and register them both visually and with digital sensors and diagnostic system Autoscanner, digital oscilloscopes or other measuring instruments capable of recording and storing the received data.

表示高速内燃机润滑系统各元件的研究参数
研究高速内燃机润滑系统元件的运行参数的问题先于台架的建立。发动机润滑系统D-246.4被选为原型。借助该台架,可以研究润滑系统的以下特性:改变发动油泵D-246.4的性能,改变和控制发动机油温度,控制机油滤清器上的压降,控制发动机油流量,在油泵入口和条件供给线上节流油到摩擦单元,测量系统对油泵吸力的真空度,记录油泵产生的油压脉动参数。为了建立船舶内燃机润滑系统中各部件的数学模型,需要确定其工作参数。在实际操作条件下,由于缺乏必要的测试设备(TE)及其安装的可能性,无法获得此类测量。详细介绍了高速内燃机润滑系统各元件参数研究台架的各组成部分及其技术特点,介绍了诊断台架,记录了研究结果,测量了发动机油压脉动的结果。该台架用于研究水泵和滤水器的运行参数。信号使用Autoscanner诊断系统进行注册。诊断系统是一个连接到个人电脑的64通道示波器。这代表研究润滑系统元件的操作参数提供了足够的机会来模拟油的供应和净化元件的操作条件,并通过视觉和数字传感器和诊断系统Autoscanner,数字示波器或其他能够记录和存储接收数据的测量仪器进行注册。
