An autonomous water supply system in the form of a pump and a well or a well allows to avoid interruptions in the water supply of a private house, summer cottage, individual irrigation system. Downhole hydraulic elevators help to raise water from a depth of 15 meters or more. A distinctive feature of all types of equipment “The owner” is a strong pressure.
The principle of operation and the device of borehole pumps Owner
Deep water elevators of the specified brand are equipped with a turbine impeller rotating by an electric motor and placed in a working chamber. When a turbine with wings rotates, a centrifugal force arises, which throws water from the center to the edges. As a result, a vacuum zone is formed in the center, into which liquid enters through the inlet pipe. The discarded water is discharged through a branch pipe at the periphery and directed to the supply pipeline. To increase the pressure characteristics and productivity, several chambers are installed in series, and the sum of their parameters gives the characteristics of the unit as a whole.
The pump is completely submerged in water. At the same time, a prerequisite for its normal functioning is avoiding contact between liquid and electronics, due to which the equipment functions. Submersible pumps Owner are of the oil-filled type. Due to this, they can be lowered to a greater depth compared to air-filled devices. The maximum diving depth below the water level is 30 meters.
The body and shaft of any pump model The owner, the shaft of the electric motor, fasteners, reinforcing inserts for the diffusers are made of stainless steel. The impellers are made of technopolymer.
The downhole pumps Owner are equipped with a safety valve that holds the water column when the engine suddenly stops. This makes it easier to restart and prevents the blades from rotating in the opposite direction.
Like any other pump, Master equipment is sensitive to voltage surges. Therefore, before starting the unit in operation, a voltage stabilizer must be connected to the network in advance.
Model range and technical characteristics
All models of the Master hydroelevators are divided into two large categories: NG and NGV, that is, submersible pumps, which can also be screw. Subcategories are numbered from 1 to 4, depending on the number of cameras, and the unit is not written. For example, model NG-1.30 and 4NGV-2.80.
The main characteristics of a representative of any model range:
- a type;
- immersion depth;
- maximum head;
- bandwidth;
- mains voltage;
- power consumption;
- rated power;
- maximum number of starts per hour.
Additional characteristics include the quality and permissible temperature of the water, the length of the power cord, weight, diameter of the pump and the thread of the outlet, the minimum diameter of the well. Water quality refers to its purity or maximum sand content.
Criterias of choice
The main criteria for choosing a borehole water-lifting device are the following parameters:
- immersion depth;
- power;
- performance;
- water supply height;
- diameter and material of manufacture of the case;
- the length of the electrical cable.
When determining the appropriate option, it is recommended to consult a specialist. An alternative way of correct calculation for the selection of equipment is specialized software.
Advantages and disadvantages
The advantages of the owner borehole pumps, first of all, are the affordable price and high head. Similar units from other manufacturers are more expensive with the same characteristics of a particular model. In addition, the domestic manufacturer took into account the peculiarities of the soil and designed the devices, taking into account the possible pollution of water with sand. Centrifugal pumps The owner provide water lifting to a height of more than 100 m, have a relatively small diameter, that is, they do not require expensive drilling of a large well.
The disadvantages of submersible pumps include:
- the complexity of self-installation;
- the need to remove the unit from the well for repair and maintenance work;
- the requirement to lay a protected power cable (the length of the supply line depends on the immersion depth of the pump).
According to the reviews available on the Internet about the Boss borehole pump, the deep water elevators of this brand correspond to the declared characteristics. Many potential owners are confused by the relatively low price and Chinese components. However, there were no specific complaints about the work of the model. There are remarks regarding the gradually decreasing pressure of the supplied water due to wear of the screw during long-term operation. However, this is the case for any pump of this type.
