Description

The proposed propeller gear: jo11; story 5 () d per ton of small M01UHOCTK differs from the first one in that the working track and turbine shaft are entirely made from one log, and jixivioi 2 is the log of the iotor. hewn lio pattern.

Nelia p. N. The turbines are equipped with a telescopic shutter on the upper guide anapara in the form of io3CTKii: ns chodvizhy blades.

For iioBijiHJeiiHH turbine speed / lOiUjTue;); 1) the wheel (rotor) was outlined on a screw rim with variable tilt angle from 19 at the top of the water inlet to 10 in the lower part at the water outlet with n.:iaBHijii t and) e A move from one yr.ia n k.yun to the follow-up.

FIG. 1 shows a log for the manufacture of a turbine rotor; in fig. 2-rotor turbine; in fig. 3 and 4-way shutter; in fig. 5-iairavl yushi annarat; in fig. 6-something: to (vnd from above; in Fig. 7-node in the section.

Tu) biia was manufactured entirely from log 1 (cj / Hr. 1), on whose joint but template 2 hemmed two to four rotor blades 3 (Fig. 2) without the use of gluing and joining O1specific j.ieMeHts. The remainder of the log is trimmed to the exact size (diameter) 4 and consists of a turbine shaft 5. The blades 3 together with the shaft 5 constitute the turbine rotor. Paddle 3 working KO.icca. in order to increase the turbine speed, the spiral curve was outlined with a changeable tilt angle from 19 upwards at the liquid inlet to 10 ° in the lower part v of its output, with a smooth transition from one tilt angle to another.

The ends of the rotor shaft are terminated with trunnions that can be provided with metal necks (not shown in the drawing); According to M9999-2, the last rotor is mounted in a bearing, with one of the bearings being supplied with a cushion for receiving axial loads (not shown in a pair). The turbine body 6 (fm1-. 7) made 5 cfs g also pz wood n has a high-pressure cylinder without a drip valve; In the cavity of the housing, an 6pvc opornl is installed, which serves as the length of the abutment abutment (not shown in the drawing).

On the case of the turbines, there is a top pass uni aiHiajiST (fig. 5 and 6). made in the form of a socket with movable vanes 7, and the blades should be even in order to: vortex liquid, HOCTvnaiOTHeff to the impeller);

With the aid of the booster apparatus, hydraulic losses are reduced and, consequently, efficiency is increased. installation, so that the liquid is delivered to the blades of the working no / i coil box at a minimum of 1m vr.TOM.

In order to avoid congestion when the liquid flow rate drops, the nshrovid telescopic shutter is used in the turbine (Fig. 3 and 4). serving to regulate the flow of fluid through the turbipu.

The body 8 of the bolt is made of wood, in which the sunflower ball 9 d.h. On the sides, the shutter has metal, metal metro) le nap1) avl yupdiye 10 for moving the shutter to the gate of the rails of the hull turbo | py.

For convenience, the shutter remepdepi, in the process of adjusting the flow rate of the fluid, hang up for the upper part of the cable 11 (Fig. 7). To transfer the rotator. 11) Pogo dvjempes from the rotor to the corresponding shank unit on the shaft of the rotor shaft and planted (not shown in the drawing).

B ;;;);) Yeseese work: Turbik. flow: -; ; efficiency with some SLO) :; Pamravl 10P1y anpara -; - enters i; a blades of the impeller. ps) c. with scarlet prpododts in .tnye movement, which (x through the screw in the first ;-; answer to the unit.

a) the control of the flow of fluid through the turbine is derived by means of an igre-shaped telescope.

The adjustment of the propulsion system is made as follows: with a full load of the turbine, it is suitable for maximum speed of the lift, the turbine li; There is a liquid amount of liquid.

If necessary, reduce turbos. i.e., to decrease the amount of the liquid to be consumed, lower the shutter until it comes into contact with the engraving device. Prp otsomom postieni zhn.dkoet comes in smaller quantities, and tughebina works node of normal pressure.

The turbine is stopped by closing the common shield with a single drop of water supply (not shown in the drawing).
