孔式喷油嘴偶件的高压液体流量测量,在国内尚未正式开展,所用试验设备也处于空白状态。本文介绍了研制的可用于批量生产中的喷油嘴高压液体流量试验台,从测量原理和方法,到试验台的基本技术参数、结构、控制系统、测量系统和使用操作。该试验台操作使用方便,工作可靠,直接读出高压液体瞬时流量值(L/min),测试快捷,测量精度高。希望能对柴油机油泵油嘴行业开展喷油嘴偶件高压液体流量测量,从而为提高产品质量,起到积极作用。 Hole type nozzle even high-pressure liquid flow measurement, not yet officially launched in China, the test equipment used in a blank state. This paper introduces the developed high pressure liquid flow test bench for injectors, which can be used in mass production, from the measurement principle and method to the basic technical parameters, structure, control system, measuring system and operation of the test bench. The test bench operation easy to use, reliable, direct reading of high-pressure liquid instantaneous flow rate value (L / min), fast test, high accuracy. Hope that the diesel oil nozzle industry to carry out the nozzle high pressure liquid flow measurement, which in order to improve product quality, play a positive role.
