The invention relates to inkjet technology, mainly to devices for the study of inkjet apparatus.

The purpose of the invention is to increase the accuracy of determining the reactive force of the active nozzle.

The drawing shows a schematic of the proposed stand.

The stand for determining the characteristics of the active nozzle of the jet apparatus comprises a housing with a gas hydrodynamic support 1 for mounting the active nozzle 2 in the receiving chamber 3 of the apparatus with axial displacement, a branch pipe 4 for supplying the active medium and connecting 5 with a dynamometer 6 connected to the nozzle 2. The case is made of two parts 7, 8, provided with an additional gas-hydrodynamic support 9, located in another part 8 of the case, and a high-pressure chamber 10 installed between the nozzle 4 of the active medium supply and the other part 8 of the case, th active portion 11 of the nozzle 2 is placed in the high pressure chamber 10 and the rod 5 is disposed between the portions 7, 8 of the housing. Parts 7, 8 of the housing is equipped with annular chambers 12.

Before starting the tests, gas-hydrodynamic supports 1 and 9 supply working gas or liquid in order to hang out the active nozzle 2. Then through the high-pressure chamber 10 into the active nozzle 2 the active medium is fed. The power supply system of the annular chambers 12 prevents leakage into the receiving chamber 3 and the high-pressure chamber 10 from the housing parts 7, 8.

The reactive force generated by the active medium flowing from the nozzle 2 is transmitted by the force 5 to the dynamometer 6. According to the reading of the dynamometer 6, the nozzle 2 is determined, and then the output flow rate of the active flow, the values of which are used to determine the operating characteristics of the jet apparatus and other energy sources. devices.

The introduction of an additional gas or hydrodynamic support makes it possible to hang out the sotslo and measure the net pulling force of the active nozzle, making almost no errors in the measurement, which improves the accuracy of determining the characteristics of the active nozzle and jet apparatus.
