How to disassemble the Vodomet pump - a description of the design and the process of disassembling and assembling the unit
A person is used to living comfortably. This definition also fits into the habitual water supply, which can be carried out in a variety of ways. For irrigation of watering a garden or a garden, as well as for arranging a system for supplying water to a house, devices of various types can be used. The owner of this design prefers to know all the subtleties of its device, so many are interested in how to disassemble a water cannon pump, one of the most popular water supply devices.
Design features of this pump
"Water cannon" is a multi-stage pump, the principle of which is based on the use of centrifugal force. It is equipped with so-called "floating" wheels and an electric motor washed by it.
It can supply water from reservoirs, open reservoirs, various wells or wells. Floating impellers provide greater hydraulic efficiency. This allows you to increase the pressure characteristic of each of the wheels and, accordingly, reduce their number. As a result, it reduces the axial dimensions of the structure, the total mass of rotating elements and, as a result, significantly reduces vibration.
Floating wheels have the ability to pass large enough particles of pollution, so less clogged. The electric motor of the pump is protected from excessive heating by a stream of water washing it. It is located above the pump part, which makes it possible to remove the power cable from the top cover, allowing you to mount the device in the well with a pipe of a smaller diameter. In addition, this arrangement of the pump is indispensable when using the design by partial immersion.
The water cannon consists of two parts: the engine and the pump compartment
The composition of the "Water Jet" includes two parts: an electric motor and a pump compartment located in a common housing. All structural elements are centered in it with an intermediate support, as well as the back and front covers. A feature of the device is the ability of the floating wheels to run into each other, which reduces the gap between the stationary and rotating parts of the pump, prevents internal overflows and increases the efficiency of the system.
Description of the disassembly-assembly process
As a matter of fact, disassembling a water cannon pump in the event of a breakdown is not particularly difficult.
It is designed so that the screwed cover holds all the stationary and moving parts, sequentially worn on the motor shaft. Thus, to disassemble the mechanism, you just need to unscrew the cover. As practice shows, it is more convenient to carry out this operation by inserting a long, durable object into one of the holes for hanging the pump on the housing.
For example, a screwdriver. The cover is turned off with a large gas wrench, the third number is suitable, or with a device designed to remove the oil filter of the car.
After repair, the device must be reassembled, which is somewhat more complicated. Although if each element is numbered during the dismantling process, there should be no problems. The disassembled design consists of several separate chambers consisting of a cover located on top and a housing. Inside is a floating wheel. Before you begin assembling the device, you need to determine which way the shaft rotates. To do this, you can briefly turn on the mechanism with the wheels removed and determine the direction of movement. The operation is necessary for the correct installation of the wheels. Each of them should be mounted so that when the shaft rotates, the blades throw water to the edge and are sucked from below, from the middle of the structure.
Next, you can proceed with the assembly itself. One of the washers is put on the shaft, on top of which a floating wheel with blades is mounted. It should be directed with the extended part up, towards the motor, with a narrow “foot” - down. The design is fixed with another washer. Next mounted glass. The first one is installed, which differs from the others in a small "belt", designed to abut the ring on the engine housing. The bottom of the glass is directed to the motor, the neck - to the exit. All remaining glasses are mounted similarly.
The last detail that will help to squeeze the entire structure will be the gasket. If it has fallen into disrepair, you can choose the right option in the plumbing store. The part is a rubber ring with a rectangular hole. The outer diameter of the seal corresponds to the diameter of the body of the floating wheel, so it accurately enters the pump.
The width of the gasket is about 15 mm. Thus, when screwing the bottom cover tightly presses the package of glasses up.

Self-repair of a submersible pump is a feasible measure. You must carefully read the description of the device, the instructions attached to it, choose the right parts that need to be replaced, and get down to business without haste. The repaired mechanism will please its impeccable service for a long time.
