Description

The present utility model relates to a low-vibration submersible pump for deep wells.

The submersible pumps are mainly used in industries such as petroleum, chemicals, coal, etc. For example, electric submersible pumps can be used for pumping liquids with flammable gas in the medium or for pumping liquids with flammable gas at the work site.

After prolonged use of the submersible pump, there is a gap between the bottom wind deflector and the pump body. Due to the high-speed rotation of the submersible pump, a relative movement occurs between the wind deflector and the pump body, which leads to greater noise

The connection method frequently used between the wind deflector and the pump body is generally the welded connection or the screw connection. However, after prolonged use, the surface of the screws will corrode, causing the wind deflector to loosen. A loose wind deflector causes a certain amount of noise pollution and in severe cases can even cause the entire submersible pump to vibrate.

The present utility model aims to provide a low-vibration submersible pump for deep wells with regard to the deficiencies in the state of the art,
a low-vibration submersible pump for deep wells, comprising a machine body, wherein a wind deflector is connected to the lower end of the machine body, and wherein the machine body and the wind deflector are connected to one another by a lower connecting component, and wherein the lower connecting component comprises a clamping block and a clamping buckle, and wherein the clamping block is connected to the machine body, and wherein the clamping buckle is connected to the wind deflector, and wherein an expansion ring is arranged on the inner wall of the clamping block, and wherein the outer surface of the expansion ring rests against the outer wall of the clamping buckle.

A clamping slot adapted to the clamping buckle is provided in the interior of the clamping block, the clamping buckle being clamped firmly in the clamping slot in order to establish the connection between the machine body and the wind deflector. At the same time, an annular recess is provided on an inner wall of the terminal block, in which an expansion ring is arranged. When the expansion ring is stretched by water, it can be ensured that there is no fluctuation between the clamping buckle and the clamping block.

The expansion ring is preferably a rubber strip that expands in water.

The submersible pump preferably further comprises a motor which is connected to the machine body by an upper connection component.

The wind deflector is preferably designed in the form of a trumpet.

A diversion pipe is preferably connected to the side wall of the machine body, a thread being provided on an end section of the diversion pipe.

The wind deflector is preferably made of a hard aluminum alloy.

• bei dieser Vorrichtung sind der Expansionsring und die Klemmschnalle aufeinander abgestimmt, um das herkömmliche Schraubenverbindungsverfahren zu ersetzen. Nach dem Auftreffen auf Wasser dehnt sich der Expansionsring aus und drückt die Klemmschnalle zusammen, um es sicherzustellen, dass die Klemmschnalle immer eng an dem Klemmschlitz im Inneren des Klemmblocks anliegt, so dass sich der Windabweiser und der Maschinenkörper nicht lockern.

Beneficial effects:

• In this device, the expansion ring and the clamping buckle are coordinated to replace the conventional screw connection method. After hitting water, the expansion ring expands and compresses the clamping buckle to ensure that the clamping buckle always fits snugly against the clamping slot inside the clamping block so that the wind deflector and the machine body do not loosen.

As in 1 shown, a low-vibration submersible pump for deep wells, comprising a machine body 1 , with the lower end of the machine body 1 a wind deflector 2 is connected, and wherein the machine body 1 and the wind deflector 2 by a lower connection component 4th are connected to each other.

As in 2 to 3 shown, comprises the lower connection component 4th a terminal block 41 and a clamp buckle 42 , the terminal block 41 with the machine body 1 is connected, and wherein the clamping buckle 42 with the wind deflector 2 is connected, and wherein on the inner wall of the terminal block 41 an expansion ring 43 is arranged, and wherein the outer surface of the expansion ring 43 on the outside wall of the clamp buckle 42 is applied.

Inside the terminal block 41 is one to the clamp buckle 42 adapted clamping slot provided, the clamping buckle 42 is clamped in the clamping slot to establish the connection between the machine body 1 and the wind deflector 2 to manufacture. At the same time is on an inner wall of the terminal block 41 an annular recess is provided in which an expansion ring 43 is arranged. When the expansion ring 43 is stretched by water, it can be ensured that between the clamping buckle 42 and the terminal block 41 no fluctuation occurs.

For the expansion ring 43 a rubber ring that expands in the water is used.
