Description

There are already known cases of use, both in the merchant and in the navy, of the initial and final parts of the pipes of the circulation system of the cooling water of refrigerators in a slightly curved form, in order to better direct the cooling water in the refrigerator.

The present invention, the pursuit of not only better suction of cooling water in the refrigerator and a decrease in the power of the circulating pump, has in mind, mainly, the use of the power of this circulating pump, for the purpose of communicating additional speeds due to suction cooling outboard water into the pipe of the circulation pump, and throwing it in the direction opposite to the movement of the vessel through the cast part of the pipe.

A characteristic feature of the proposed fixture is that both the inlet of the circulating pump pipe and the outlet pipe have a direction almost parallel to the outer shell of the ship hull, in a particular case parallel to the bottom shell of it.

For the best direction of the cooling seawater to the initial part

(185)

the pipe of the circulation pump and ejection through the final part of the cast pipe; in the bottom of the pipe outlet in the bottom, there are arranged cutting-edge holes, bounded on both sides by curves, in such a way that a similarity of a nozzle is obtained in the plan.

In FIG. 1 depicts a military sudo, equipped with the proposed device; FIG. 2 - view of device with, side; FIG. 3 - its bottom view (on the bottom part).

The vessel 3 (Fig. 1) is equipped with a circulation pump, the inlet and outlet parts of the pipe of which have a direction almost parallel to the outer landing of the ships, in particular, parallel to the bottom landing of the ships.

Water jets are directed from the refrigerator along arrows I (Fig. 2).

In order to direct the cooling outboard into the initial part of the pipeline of the circulation pump and to eject it through the final part of the discharge pipe, joint-like nozzles 2 were applied, bounded from two sides in such a way that a plan like a nozzle is obtained.

In order to make the best use of the proposed fixture, it is not necessary to provide both the initial part of the receiving pipe and the final part of the ejection hole with flat nozzles located across the width of the ships.

The proposed adaptation can also be used in the case when outboard water is used for cooling internal combustion engines, for example, in modal boats and especially torpedo boats.

The subject matter of the invention.

A device for increasing the speed of a ship using auxiliary ship mechanisms (circulating pump), characterized by the use of gearbox gaps 2, bounded on both sides in such a way that a similarity of the nozzle is obtained (Fig. 2-S).
