The next summer cottage season will start very soon, which means that all lovers of this type of recreation need to prepare for it. Not a single cottage will be suitable for living, growing crops and ornamental plants if there is no water for irrigation on it. In places where there is no centralized supply, it is mined:
- The old fashioned way from the wells
- Using a well drilled at the site.
And in both cases, a pump will be an indispensable device for pumping it. The best option for the so-called summer cottage use is a submersible screw pump for a well and wells ... Its main advantage is its simplicity of construction, which means:
- Low cost.
- Low electricity consumption.
- Reliability and long service life.
At the same time, the equipment does not require any special installation, installation or preparatory operations. It is enough to simply completely immerse it in the water of a well or well and connect it to a household electrical network (220 V).
Schematic diagram of the device
The screw pump is a housing with an inlet and outlet. It contains a screw, the design of which was invented by the ancient Greek scientist Archimedes (a similar principle is used in the classical meat grinder). Its rotation around its axis using the rotor of a compact electric motor (hermetically installed in a single pump casing) allows:
- Pump water into the pump working chamber.
- Supply liquid through the outlet through the hose to the consumer.
The maximum lifting height of water through a flexible or stationary pipeline directly depends on the power and performance of the pump itself. When choosing a device, it is necessary to be guided by the depth of the well or well, plus a margin to create sufficient pressure, as a rule, 1 m for every 10 m distance to the minimum point of the water level.
And the most important advantage of screw (screw) type pumps. They are capable of pumping silted water or water containing sand particles through themselves without much damage to wear. The gaps between the propeller blades and the walls of the working chamber allow for the operation of this type of equipment in harsh conditions.
