(54) PUMP

I-. ; :

The invention is RELATED to the pump area.

The well-known pump includes a housing in a working wheel, which is finished on the shaft with a collar {1 | fixed in axial vadrav leviv relative to the body.

Such a pump is designed as a single drive with an actuator, with which it can be installed on various other wired devices.

A pump is also known, comprising a housing, an impeller, which is attached to a hub, placed in undershirts by fixing its axial position relative to the coryca and to the full hollow to install the drive output shaft in it.

The disadvantage of this pump is that it is connected to the drive, the JB of which must be made special (the syngus is the method for fastening the bushings;

The aim of the invention is to enable the quick installation of a pump on a W.-x drive not intended for a pump, for example, a shaft of a boat motor, but rather a quick disassembly.

This is a cosiness that the sleeve is rigidly attached to the shaft of the Red shaft, and tsopayc is free to carry out the input cable into the ampoule for transmitting the reactive taoMsssr & on. drive unit.

On, 1 schematically, iravapan zheny prodipyddy pump; on the city of 2 a boat motor before installing the Hacocaj on the city of. 3 - a project for transporting cargo from a tank or reservoir.

Claims (2)

The pump dd of the output shaft1-T1reiыiv1essF of the boat motor 2 has a housing 3 with underplates 4 and an impeller mounted on a hollow fixture 6, fitted with under-supports 4. The impeller 5 and the inside of the bearing 4 are mounted on the sleeve 6 by means of a nut 7, and As external clips 4 are fixed relative to the housing casing 3, then the sleeve 6 is also fixed relative to the housing 3. On the sides of the bearings 4, sealing sleeves 8 are mounted in the housing 3, which together with the sleeve 6 form a cavity 9 in the housing, filling greased; The internal layout of the VTU / 1KI 6 is made of a size that provides a rigid connection with the output shaft 1 of the drive. From turning on the shaft 1, the sleeve is fixed by means of a pin 10, which is provided for gears in the torque from the motor 2 to the rowing; screw 11 (see Fig. 2), and from the axial displacement, the sleeve 6 is fixed with a counter nut 12, 3 is provided with a cover 13, which forms the flow part of the pump with the impeller 5. In the housing 3 of the outlet it is also a collector equipped with a branch pipe 14 to which the flexible hose is connected. The cover 13 is provided with a quick-detachable grid 15 protecting the flow part of the pump from damage. The grid 15 is secured in the lid 13 by means of a rotary ring 16. The housing 3 is provided with a lever 17, i.e. -V- ..-. d-- , -.-. the forked end to provide the body of some kind of freedom about my. Torah. 2. The lever 17 is intended only for transferring the reactive torque to the motor 2, the pump is mounted to the boat motor 2 as follows. After removing the propeller 11 from the output shaft 1 of the pump 15, then the pump, as a whole, sets the vsi shaft 1 so that the sleeve is pressed into pin 10, and the forked end of the lever 17 engages the motor 2 on both sides This screw the nut 12, lock it and install the grid 15 in the cover 13, fixing it with the ring 16. Since the housing 3 is connected to the motor only with the forked end 17, providing some freedom to the pump both in the angular displacement and vertical direction when installing the pump is provided by the computer Installation and technological errors. The fssss of the sleeve 6 relatively led i and the casing 3 loavol pieces when installing the pump, prefigure the specified clearances in the hydraulic path of the pump, ensuring that it is hydraulically stable, without additional adjustments. The simplicity of mounting the pump to the motor 2 makes it possible to produce a naughty and fast replacement of the propeller 11. After installing the pump on the boat motor 2, it is immersed in water, and after starting the motor 2 through the gearbox of the latter, the torque is given through the output shaft 1 to the impeller 5. The pump provides: Fluid supply to the consumer. FIG. 3 shows the use of a pumping unit with a boat motor for transferring water from any tank or reservoir. Constructive dimensions as well as pairs of meters of the Pump should be consistent with both the type of engine and several types having HOI output shafts of a small size, as suggested, the pump can be installed on the output shafts of the drives not intended for this. Claims of the invention A pump comprising a housing, an impeller mounted on a sleeve housed in a base fixed axially relative to the housing and made hollow for mounting an output drive shaft in it, which is characterized in that in order to speed up installation and disassembly and use as a boat motor tfivoda, the sleeve is rigidly connected to the shaft, and the body is made free relative to the drive and has a lever for transmitting the reactive torque to the drive.
