Rodnichok pump - technical specifications, operating principle and customer reviews

Autonomous water supply is not a luxury at all. Not a single country cottage or country house can do without it. To equip the system, different devices can be selected. Many factors must be taken into account: the depth of the well or well, the amount of water needed by the consumer, the type of soil, and much more. Many summer residents decide to buy a fontanel water pump, and are satisfied with their choice.

How is this pump arranged and functioning?

The design of the fontanel is very simple. Two main elements are located in the body, allowing the mechanism to pump water. This is a vibrator and an electromagnet. The first is an anchor with a pressed rod with a spring of rubber acting as a shock absorber.

It is rigidly mounted on the shaft. The shock absorber is limited by a special sleeve. A rubber diaphragm fixed at a certain distance from the shock absorber guides the rod and is an additional support for it. In addition, it closes the hydraulic chamber and separates it from the electric one.

The scheme of the pump Rodnichok

In the electrical compartment there is an electromagnet consisting of a winding and a p-shaped core. Two coils connected in series are windings. Both elements are placed in the housing and filled with a compound that performs several functions at once: it helps to remove heat from the coils, secures the parts in place and provides the necessary insulation. In addition, the fontanel pump device involves the installation in the housing of a special valve that closes the inlet openings. If there is no pressure, water flows freely through a special clearance.

When you turn on the device, the core begins to vibrate at a speed of 100 times per second

After the device is turned on, the core begins to attract an anchor. The shock absorber drops anchor once in half a period. Thus, in one period of the current wave, the anchor manages to be pulled to the core 2 times, given that the standard frequency of 50 Hz results in 100 attraction per second. A piston mounted on a rod with an anchor also vibrates with the same frequency. A hydraulic chamber is formed whose volume is limited by a valve on the body and piston. The water pumped by the pump has a certain elasticity, due to the dissolved and undissolved air present in it.

Thus, when the piston moves, it unclenches like a spring and pushes excess fluid through the discharge pipe. A valve on the housing allows water to flow in and prevents it from leaking through the inlets.

Why choose this particular device?

Initially, the Rodnichok vibration pump was designed to supply water from wells, boreholes, pump out fluid from basements, drain flooded areas and aeration.Due to their design features, the first models could only work near the power source, the latter are devoid of this drawback. The installation has a number of indisputable advantages:

• The maximum pressure of the device is 60 m, which makes it possible to lift water from a well or a well into a two-story building.
• The rated power is 225 W, so the pump can be used in tandem with low-power generators.
• The maximum particle size that can be skipped by the mechanism is 2 mm.
• The outlet pipe has the most common and popular ¾ inch diameter.
• The installation is completely safe thanks to full waterproofing and double insulation of all electrical parts.
• The maximum pump capacity of 1500 l / h makes it possible to equip several points of drawdown at once.
• A non-return valve integrated in the system prevents fluid from draining from the mechanism.
• The device does not require additional special maintenance during the entire period of operation.
• The inlet fitting is located at the top of the mechanism, which prevents the capture of dirt and silt from the bottom of the tank or well.

What owners think - customer reviews

First of all, everyone notes the very affordable cost of the device. It absolutely does not hit the budget and allows you to provide water for the site for more than moderate money. When the mechanism breaks down, many people prefer to buy a new one instead of repairing it. Despite the fact that the deep-well pump, the fontanel is designed to operate at a mark of no more than 10 meters, thanks to the five-fold strength inherent in the calculations, it is lowered to great depths. On the Internet you can find many reviews of the owners of such installations, which successfully operate at twenty and even forty meters.

The pump can work in a well, well, or simply pumping water from a pond or reservoir

The main problem in this case, as experience shows, is the length of the network cable. It happens that he is simply not enough. Some, without hesitation, simply lengthen the cord, increasing it in ways that are accessible to them.

For insulation use a sleeve or ordinary electrical tape. It should be noted that this is quite dangerous. Intervention in the wiring is generally unacceptable and potentially dangerous, in addition, such a device automatically loses the right to warranty service.

In general, a fontanel pump for a well has established itself as an inexpensive practical device for providing a site with water. If you follow all the requirements of the instructions for its installation and use, the mechanism will serve impeccably for many years.
