射流技术是近年来发展起来的一种新技术,它利用流体在特定的元件中流动的某些物理效应来实现自动控制。射流控制装置比较稳定可靠、经济简单,易于制造和适应性较强,固此近两、三年来得到迅速推广,已在许多方面得到应用。沈阳铸造厂的工人师付在打好铸造工业翻身仗中,发扬了敢想、敢干、敢闯的革命精神,经过反复试验,终于成功地把射流技术应用于水力清砂系统的回水槽液面控制和泵房污 Jet technology is a new technology developed in recent years, it uses the fluid to flow in the specific elements of some of the physical effects to achieve automatic control. Jet control device is relatively stable and reliable, economic simple, easy to manufacture and adaptability, solid nearly the past two or three years has been rapidly promoted, has been applied in many ways. The workers in Shenyang foundry paid for it to take a turn for the better in foundry industry and carried forward the revolutionary spirit of dare to think, dare to do and dare to break through. After repeated tests, it finally succeeded in applying the jet technology to the backwater tank of the hydraulic sand-cleaning system Surface control and pump room contamination
