Description

As nsjiecTiio, the purpose ioviiein upoiiajio / uiToabiiocTii dontro6o; kiogo pump claim automation of its filling, the pump ustanan.tppayut to the shaft below the static water level in the soil, for which purpose) sasyvayui1os knee irisoedin pump obsadio1 added to tube 1 below statncheskogo yiioBHu codes in the ground. However, this method is very time consuming and inconvenient when installing the pump in a flow well.

The optics removal method eliminates the indications of a shortage and is due to the fact that the pipe with a plug-in | 1: cut into the obsadia pipe after; Josadg in it iiaHopiioit pipe, it is allowed up to dia). and the pump is connected to the pump after the slinging of the Hturopiioii trubtle and the bridge, the ggi of the trap; kk1G.

FIG. 1, 2, 3, II, 4 depict the end result of the installation of the pump in a tubular well.

A tubular well 1 is constructed in a tubular well with a depth below the depth of the center of the centrifugal pump. Bepxiuiii the end of the casing 1101 of the pipe 2 must be distributed: the same 11 above the line of the static levels in the well. In the casing 2 insert a pressure pipe 3 of mepugo diameter, at the end of which a gland is mounted 4. Lowering the gland; to the level of D1; and mine (Fig. 1).

After installing HanopHoii, pipe 3 with the stuffing box in the intertube space will not be above the water seal, iiaHopHbiii ypoiscHb odes will be installed in the nano tube. At some level from the bottom of the mine casing 1, the pipe is screwed or cut. The end of the remaining 1 cc) pipe is disassembled to connect the flange; from the top, through the nanor pipe, in the open nanohonn, the valve 5 Lud.lo, which by means of the flanges 6 is attached to the casing pipe, is lowered, and from the top to the valve the connecting pipe 7 (Fig. 2).

When the valve is installed on the pipe - and the gland 4 with the nano-pipe 3 is lifted and installed in the pipe 7, the valve 5 is closed and the water from the well above the port N ° 88281-2 is closed

krashast (fig. 3). Next, the pipe 7 is disconnected from the valve 11 together with the pipe 3 and the gland is removed from the shaft. When the valve is closed, the pump nozzle 8 is connected to it, and then the centrifugal pump 9 mounted on the foundation 10 is connected. A pressure pipe 11 is attached to the pump (Fig. 4).

To start the installation, it is necessary to open the valve 5 and then water under natural pressure will flow into the centrifugal pump 9 and be installed in the discharge pipe 11 on the static level line in the ground, after which the installation is considered ready for action.

This method significantly improves the installation conditions of the pump in the flowing well and makes it possible to widely use the installation of pumps in tubular wells below the static water level in the ground.

Claims (2)

1. A method of installing a pump in a tubular well below a static level of water in the ground by connecting the pump suction elbow to the casing, characterized in that for ease of installation work in the flowing well, the Ludlo valve cuts into the casing after the central pressure pipe is seated on the bottom of the shaft. 2. Acceptance of the method according to claim 1, characterized in that. that after the valve is inserted, the central pressure pipe is lifted, the valve is closed and the valve 1 is pressed to it: its pump knee. baud day 7777777/7, Figure 1 Static LAUNCH 5ODY Line center. .
