How the submersible vibrating pump works

Many summer residents, who have a well, well or a pond on the site, know very well what the vibrating submersible pump "Malysh" is. Historically, it turned out that this brand of such pumps acquired the title of "people's", becoming incredibly popular. In principle, any submersible vibrating pump, regardless of the manufacturer, operates on the same principle. Our today's article is devoted to this particular group of devices.

Raising water

In order to raise the liquid from the source to the point of analysis, a pump is needed. There are several basic modifications of them, differing in both the installation and the principle of operation. Depending on the placement, surface and submersible models are distinguished. All the vulnerabilities of the latter are completely hermetic, which makes it possible to constantly keep such a pump under water, removing only for the performance of service. Such models push water through a pipeline, rather than create a vacuum. The submersible vibrating pump is the most affordable modification. Centrifugal devices, which use a system of intake wheels, as well as worm gears with worm gears are much more expensive.

An ordinary electromagnet

The submersible vibratory pump is very simple. It is based on a double laminated core made of electrical steel (as in induction transformers). On the fixed part there is a winding, which, when passing a current, creates a magnetic field. This element is hermetically sealed with a compound. The other part is made mobile - it has two degrees of freedom. When a current appears in the coil, the movable part of the core is attracted to the stationary part. Let's look at how a submersible vibrating pump works.

Principle of operation

On the opposite side of the movable core is placed a metal rod on which a rubber disk-shaped piston is attached. The core itself is fixed in the pump casing with a dense elastic "skirt" made of rubber - a vibrator. When power is supplied to the coil, a magnetic field arises and attracts the movable part of the core. The piston located in a special compartment, pulling back, creates a vacuum, and through the non-return valves, water from the outside rushes into the chamber. Since the current is variable, then when the sine curve passes through zero, the field per millisecond fades, and at that moment the vibrator skirt pushes the core with the piston back, thereby creating pressure. The water from the chamber can not flow back because of the check valves, so it rushes into the outlet pipe. Then the current again increases, and the steps are repeated. The number of movements of the piston is equal to the frequency of the network, that is, 50 Hz (once per second). This is how a submersible vibrating pump works. Reviews about it, despite the effectiveness, are contradictory.

Features

Such solutions have two significant drawbacks, which do not allow us to recommend these types of pumps to ubiquitous use. The first is the vibration of the hull, caused by the very principle of work. It is believed that such pumps can not be used in wells in which collapse or undesirable soil layers may occur. We recommend installing such solutions only in wells or water bodies, rather than in narrow wells where vibration can destroy the walls. The second drawback is the rapid wear of the rubber parts of the product due to the constant load. With intensive work, an annual audit is required with replacement of the piston.
