Many summer residents who have a well, a well or a pond on the site know very well what a vibration submersible pump "Kid" is. Historically, it was this particular brand of such pumps that acquired the title of “national”, becoming incredibly popular.
In principle, any submersible vibration pump, regardless of manufacturer, works on the same principle. Our today's article is dedicated to this particular group of devices.
Raising water
In order to raise the fluid from the source to the parsing point, a pump is needed. There are several basic modifications that differ both in installation and in principle of operation. Depending on the location, surface and submersible models are distinguished. All the vulnerabilities of the latter are completely sealed, which makes it possible to constantly keep such a pump under water, removing it only for servicing. Such models push water through a pipeline, rather than creating a vacuum. Vibration submersible pump is the most affordable modification. Centrifugal devices that use a system of intake wheels, as well as screw with a worm gear, are much more expensive.
Ordinary electromagnet
The vibrating submersible pump is very simple. It is based on a dual lined core made of electrical steel (as in induction transformers).
A winding is located on the fixed part, which creates a magnetic field when current flows. This element is hermetically sealed with a compound. The other part is movable - it has two degrees of freedom. When a current appears in the coil, the movable part of the core is attracted to the motionless one. Let's look at how a vibrating submersible pump works.
Principle of operation
On the opposite side of the moving core from the coil, there is a metal rod on which a rubber disc-shaped piston is mounted. The core itself is fixed in the pump housing using a dense elastic "skirt" made of rubber - a vibrator. When power is applied to the coil, a magnetic field arises and attracts the moving part of the core. The piston located in a special compartment, moving away, creates a vacuum, and through the check valves water flows from the outside. Since the current is alternating, when the sinusoid passes through zero, the field fades for a millisecond, and at this moment the vibrator skirt throws the core with the piston back, which creates pressure.
Water cannot flow back from the chamber due to
check valves, therefore it rushes into the outlet pipe. Further, the current increases again, and the steps are repeated. The number of piston movements equals the network frequency, i.e. 50 Hz (once per second). That's how the vibrating submersible pump works. Reviews about it, despite the effectiveness, are contradictory.
Features
Such solutions have two significant drawbacks that do not allow us to recommend these types of pumps for widespread use. The first is the vibration of the case caused by the principle of operation. It is believed that in wells where collapse or the appearance of unwanted soil layers is possible, such pumps cannot be used. We recommend that such solutions be installed only in wells or bodies of water, and not in narrow wells where vibration can destroy walls. The second disadvantage is the rapid wear of the rubber parts of the product due to the constant load. With intensive work, an annual revision with the replacement of the piston is required.
