Description

The invention relates to the field of pump engineering and can be used in pumps for pumping liquid metals.

According to the main author. St. No. 773312 is known a pump for pumping molten metals, comprising a housing and an impeller mounted on it with a shaft mounted on a shaft with a shell over the outer diameter, and through holes in the shell are located along its entire length [1] ·

However, the support of the shaft of the cantilever impeller is exposed to the high temperature of the pumped molten metal because the shaft is solid. As a result, the reliability and durability of the pump is reduced.

The aim of the invention is to improve the reliability and durability of the pump.

I

This goal is achieved due to the fact that the impeller shaft is made integral and its parts are connected outside the housing by means of a detachable coupling, and a hydrodynamic sliding bearing is installed on the side opposite to the wheel.

The drawing shows the proposed axial pump for pumping molten metals, a longitudinal section.

The pump includes a housing 1 and an impeller 3 mounted on a shaft 2 mounted on it with a shaft 3 with a shell 4 over its outer diameter. In the shell 4 is made through holes 5, arranged in rows along its entire length. The shaft 2 is made composite and 10 parts 6 and 7 are connected outside the housing 1 through the split sleeve 8 and the housing 1 on the side opposite the impeller 3 is mounted hydrodynamic sliding bearing 9 on vnut 15 renney sleeve 10 is also provided with through holes eleven.

Part 6 'of the shaft 2, located inside the housing 1, rests on the hydrodynamic sliding bearing 9 and the shell 4, 20 and part 7 is located in the bearing unit 12, which can be made water-cooled, for which provided

holes 13 and 14.

25 The pump operates as follows.

The impeller 3 pumps the molten metal into the pressure line (not shown). The metal enters the hole 5 of the shell 4 and creates a hydrodynamic effect. The same effect appeared879031

He was also in the hydrodynamic sliding bearing 9.

When the pump is running, the high temperature from the pumped liquid mainly extends only to the detachable coupling 8. The bearing unit 12 is cooled with water supplied to the unit 12 through the holes 13 and 14.

With this implementation of the pump increases the durability of the support and the reliability of the pump as a whole.
