(54) HYDRAULIC STAND

fastening the measuring tank pallet, suspended springs.

The measuring tank is located in the cavity of the drain cup 8, connecting:; The vertical stand through the valve 1O connects to the sewage system and, passing inside the supply tank, the 3 upper parts end with a telescopic ycTpoECT & oMs which is fixed to the pressure tank I .. A discharge line 12; connected through Kpaii 13 to the water supply system, it passes through the cavity of a vertical stand-Sh and connects to the supply tank 1. Expendable tank with the help of pipeline 14; passing through the telescopic connection} is connected to the pressure tank 11,

A closed fluid flow in the stand is created by a pump 15s connected to a pressure line through valve 1.6,

Measuring the flow. the liquid-t through the working area is made by filling the measuring tank 5. The time is determined from the electric stopwatch 17e activated by the contact 18 The valve of the 6-dimensional measuring tank is connected to the handle 19 by means of a cable

The vertical stand is reinforced with a piezoelectric: sl-mt 2O for measuring pressure perepad on the working section and a cylinder 21 with tinting; -the liquid introduced into the working section during the study of conical and turbulent flows

Works on. the stand is carried out as follows.

When operating in a closed circuit, the taps Yu and 13 are closed, the drain tank 8 is filled with shdkost- From the tank 8 through the drain pipe 9, the liquid enters the pump 15 and through the valve 16 is fed into the supply tank 1, from where the main cruise goes to the working section 2, and A small amount of liquid enters the pipeline 14 3 pressure tank 11 and is discharged from it into the cavity of the vertical drain.

When the valve 4 changes the flow rate of fluid through the working section 2, the flow through the pressure tank remains unchanged, which ensures the preservation

hydrostatic pressure in the supply tank 1 o

The measurement of the flow rate of fluid through the working area is drying out. There is a wipe at the beginning. At the beginning of the measurement, the x-slang - tank is closed with a cable.

5 and include electrical sluch.- .og.;. Aomer 17 ° The liquid flowing from the working section through the valve 4 fills the measuring tank, the latter is lowered together with the podrhinny end of the pallet 7 and closes the electrical contact 18, turning off the stopwatch for a given amount of fluidity in the measuring tank.

The stand can also work along the way ™ whip scheme. At that, the valve 16 is closed, 1 taps 1O and 13 are opened. Liquid from the external line goes through the valve 13 to the pressure pipe 12, then to the supply tank 1 and the working section 2, from where it is drained through the drain tank 8 and the pipeline 9 into the cavity of the vertical rack and Crane 10 - in the sewer.

In the study of processes, the flow through the nozzles and holes in the working area

2 replacing connoMs with a deceptive clip

3 on the supply tank 1; A jet of liquid flowing out of the nozzle falls on the pallet 7 and flows along it into the measuring tank 5 o
