The best option for arranging a water supply system in a private house is a submersible pump with automatic equipment. The work of the home system in an autonomous mode solves the problem of continuous water supply to all nodes of the water supply system, regardless of the number of storeys and area. You need to choose a submersible pump for a well or a well based on its technical characteristics, depth of water intake, height of its supply, after calculating the estimated volume of water consumption.
Scope and types of submersible pumps with automation
Automatically controlled submersible pumps are used to provide water to a residential building, irrigation systems for a household plot, or to pump out sewage, melt water, and sewage in the event of damage to the drainage system.
Pumps come in several forms:
- Deep centrifugal working principle for clean water. They are lowered into wells with a depth of 10 to 50 m or more. Cylindrical body made of stainless steel or metal with anti-corrosion coating. They have high bandwidth. Duration of work depends on the manufacturer and operating conditions.
- Vibrating. They are installed in shallow wells and wells up to 10 m. Unlike centrifugal wells, they can pump water with a light suspension formed during operation. There is a caveat: vibrations contribute to the subsidence of soil around the casing. Periodic cleaning of the bottom funnel is required to prevent equipment breakdowns.
- Drainage submersible pumps with pressure sensor. There are two types: centrifugal and vibrating. Designed for pumping water with impurities of rocks, large inclusions. The species is fecal. In the bottom there are filter holes that determine the size of the transmitted particles. Effectively work at a depth of 2 m.
On centrifugal and vibration devices, a check valve is installed. It is mounted separately. Designed to prevent the return of water from the system to the well.
Types of Automatic Systems
The operation of submersible pumps with automatic start is regulated by one of three types of equipment:
- Accumulator systems. Integrated automation monitors the fullness of the inner membrane. When the pressure drops, the relay activates and water intake starts. This is the easiest type of automatic control, adjustable by a built-in pressure gauge.
- Electronic relay device with a set of sensors on the pump housing and on the walls of the pipeline. The sensor in the pipe, responding to a decrease in pressure, turns on the motor. With this type of automation, a hydraulic accumulator is not required.
- The operation is controlled by an electronic device with high sensitivity sensors. Each system is customized to individual customer requirements. Programmable automation also controls the flow rate and volume of fluid.
The choice of automation system depends on the expected loads, cost and complexity of maintenance.
Criterias of choice
Equipment for the water supply system is selected according to several important parameters:
- appointment;
- characteristics of the water in the source.
- automatic submersible pump performance, which shows the amount of water flowing per minute, hour;
- the height of the water column created by the pump;
- well depth;
- communication wiring height;
- length of water supply network.
The nominal parameters indicated in the technical documentation differ from the actual ones. The manufacturer does not take into account the length of the network wiring. In the calculations, it should be taken into account that every 10 m of the horizontal corresponds to 1 m of the vertical column.
Mounting Features
Depending on the complexity of the installed automation, installation can be performed independently or consult a specialist. Systems with a hydraulic accumulator and a relay block are simple - they can be connected with your own hands according to the attached circuits in the same way as a non-return valve.
For uninterrupted operation of programmable electronics, installation and service must be performed by qualified specialists.
Advantages and disadvantages of automatic devices
Submersible pumps with automatic control of the water supply are distinguished by the principle of operation, power.
Centrifugal devices have a high margin of safety. The cylindrical elongated shape allows you to install them in the casing up to 20 cm in diameter. The powerful flow created inside the motor blades, takes the fluid without damaging the well. Installed permanently. Service life, as a rule, exceeds specified by the manufacturer. Clean the filters regularly. Works in clear water. If turbidity occurs, the motor may fail.
To take water from a well or a shallow well, it is better to install vibration models such as Grundfos. The best option for summer cottages, since their capacity is enough to provide small home ownership or watering the plot. Compared with centrifugal, they have a smaller working resource.
