Abstract

The invention relates to an equipment for processing abrasive slurry water-jet microporous nozzle internal runner and a method for detecting and controlling real-time flux. The equipment comprises an oil tank, a slurry box and a high-pressure material tank; a high-pressure pipeline and an oil returning pipeline are communicated with the oil inlet of the high-pressure material tank and the oil tank; a material inlet pipe and a material supply pipe are communicated with the material inlet of the high-pressure material tank and the slurry box; the oil inlet of the high-pressure material tank is provided with a high-precision flowmeter; a processed microporous nozzle is communicated with a material supply interface; the inlet of the material supply joint is provided with a check valve; the material supply joint is arranged on a clamping device; the real-time oil inlet quantity of the high-pressure material tank, namely the real-time flux of the processing microporous nozzle, is measured by the high-precision flowmeter; the real-time slurry flux detection data is input to a controller; when the slurry flux reaches a given value, the controller outputs a control signal to close the check valve, thus stop processing. The equipment has high grinding efficiency and high precision.

Description

Technical field:

[0001] The invention relates to an abrasive slurry jet micro-hole nozzle internal flow path processing equipment and a real-time flow detection and control method. Background technique:

[0002] In industrial production practice, the application of fluid flowing through microporous nozzles is very extensive. For example, in the fuel injection system of internal combustion engines, high pressure is used to inject fuel from the microporous nozzles of the injector body to atomize the fuel; In the engine, the cooling system cools the system by spraying cooling gas through the microporous nozzle; in the high-precision bearing system, the microporous nozzle is used to spray lubricant to lubricate the bearing and so on. In applications such as these, the control of the micro-orifice nozzle flow is very important, and small differences in flow error can affect the overall performance of the product.

[0003] In practical applications, when the aperture of the micro...
