SU1343086A1 - Device for determining sprayer flow characteristics - Google Patents

Abstract

The invention makes it possible to increase the accuracy of measurements and reduce the time of testing the nozzle by visualizing the spotting of individual jets at the entrance to the receiving tubes and eliminating the pressing and releasing operations with additional adjustments to the device. To do this, under the diffuser 1, a container 11 is installed coaxially with it and with the possibility of its rotation around the axis of the atomizer. A coaxial drain hole 14 is made in the lower part of the container. In case of complete or partial mismatch of the axes of the nozzle openings of the sprayer with the corresponding tubes 5, the liquid catcher from the tank 11 flows into the hole 14 and through the discharge tube 15 into the liquid collector. By turning the catcher, there is no leakage of liquid from the tube 15. This indicates that liquid jets accurately hit the corresponding holes in the tube-ca. 5 catcher. 2 Il. 1O ate lo 4 CO o oo Oi

Description

11 V

H-loripfTOHne refers to the digger with rpoiMiiiK), for example: to test T (H1NN (11 diesel devices, and can be used to determine the discharge characteristics of the sprayer nozzle by separate nozzle orifices).

The purpose of the in-field test is to continue (1) measure measurements and reduce test time by visualizing the intersection of individual jets at the inlet to the receiving tubes and to exclude the pressing and release operation with additional settings of the device.

FIG. 1 is a diagram of a pre-jiaraeMoi o device; in fig. 2 - catcher with additional capacity, incision.

The device for determining the flow characteristic of the distributor 1 by its separate nozzle holes installed in the body 2 of the nozzle with the supply nipple 3 contains a liquid trap 4, made in the form of tubes 5 whose receiving channels 6 are aligned with the corresponding nozzle holes at a distance specified from them and in series with the catcher D the defoamer 7 and the measuring device 8, made in the form of a series of beakers 9, connected through the antifoam 7 with the help of hoses 10 s 5. The logging apparatus provided with an additional tank 11 installed under the atomizer 1 coaxially with the possibility of turning around its axis rasishitel. At the same time in the container 11 is fixed in the grooves 12 of the clamps 13 of the tube 5, and in its lower part there is a coaxial drain hole 14 connected to the outlet pipe Kof i 15 with the liquid collector 16. The removal of liquid from the measuring device 8 is carried out with a pomop of the locking device 17.

The device is mounted on the bottom plate 18, connected by two columns 19 with the top plate 20, on which the nozzle housing 2 with the tested sprayer 1 is placed. On the bottom plate 18 there are two hydraulic cylinders 21 moving the mobile yoke 22 along the racks 19.

The additional container 11 is placed in the holder 23 and its rotation around the axis of the atomizer 1 is carried out using the handle 24.

Device To determine the pacxd.i characteristic (sprayer works as follows.

The atomizer 1 mustache; tantalized into the cage 23. With the help of hydrocicles 21, the movable yoke 22 is raised to the upper position, in which the end 1) of the aspirator 1 abuts against the end of the nozzle 2. Include the flow of test fluid through the nozzle 3 supply.

In the case of complete or partial misalignment of the axes of the copole openings of the sprayer 1 with the corresponding tubes 5 of the catcher 4, the liquid from the additional tank 11 will flow down into the hole 14 and through the discharge tube 15 into the liquid collector 16. By turning the catcher 4 by means of the handle 24, there is no leakage of liquid from the tube 15, which indicates that the liquid jets accurately hit the corresponding holes of the tubes 5 of the catcher 11.

In this case, the fluid through the hoses 10 through the defoamer 7 enters the beakers 9 of the measuring device 8. After measuring the flow of the fluid by the con

Cut off the liquid supply through the nozzle 3 to the left openings of the sprayer 1, lower the yoke 22 down and remove the sprayer.

The proposed device allows 35 to significantly improve the measurement accuracy and to reduce the test time by about 30% due to the convenience of eliminating jet spraying when installing the spray gun. ten
