Avoid failures in the water supply of a private house, cottage, individual watering system allows an autonomous water supply system in the form of a pump and a well or a well. Downhole hydraulic elevators help lift water from a depth of 15 and more meters. A distinctive feature of all types of equipment The owner is a strong head.
Principle of operation and arrangement of borehole pumps
The deep water lifts of the indicated trademark are equipped with an impeller-turbine rotating with the help of an electric motor and placed in the working chamber. When a turbine with wings rotates, a centrifugal force arises that throws water from the center to the edges. As a result, a rarefaction zone forms in the center, into which liquid enters through the inlet pipe. The rejected water is discharged through a pipe at the periphery and sent to the supply pipe. To increase pressure characteristics and productivity, several chambers are installed sequentially, and the sum of their parameters gives the characteristic of the unit as a whole.
The pump is completely immersed in water. At the same time, a prerequisite for its normal functioning is the avoidance of contact between liquid and electronics, due to which the equipment functions. The owner submersible pumps are oil-filled. 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 housing and shaft of any pump model The owner, motor shaft, fasteners, reinforcing inserts for diffusers are made of stainless steel. Impellers are made of technopolymer.
Borehole pumps The owner is equipped with a safety valve that holds a column of water when the engine suddenly stops. This facilitates its restart and prevents the blades from rotating in the opposite direction.
Like any other pumps, the equipment owner is sensitive to power surges. Therefore, before starting up the unit, a voltage regulator must be connected to the network in advance.
Lineup and Specifications
All models of the Host hydraulic elevators are divided into two large categories: NG and NGV, that is, deep pumps, which can also be screw. Subcategories have a serial number from 1 to 4 depending on the number of cameras, and the unit is not written. For example, the model NG-1.30 and 4NGV-2.80.
The main characteristics of the representative of any model range:
- a type;
- immersion depth;
- maximum pressure;
- 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 threads of the outlet, and 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 lifting device are the parameters:
- immersion depth;
- power;
- performance;
- water supply height;
- the diameter and material of the housing
- cable length.
When determining the appropriate option, it is recommended to consult a specialist. An alternative way to correctly calculate the selection of equipment is specialized software.
Advantages and disadvantages
The advantages of borehole pumps The owner, in the first place, is the affordable price and high pressure.Similar units of other manufacturers are more expensive with the matching characteristics of a particular model. In addition, the domestic manufacturer took into account the features of the soil and designed the devices, taking into account the possible pollution of water by sand. The host's centrifugal pumps 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 large wells.
The disadvantages of submersible pumps include:
- complexity of self-installation;
- the need to remove the unit from the well for repair and maintenance;
- requirement of laying a protected cable for power supply (length of the supply line depends on the immersion depth of the pump).
According to online reviews of the Boss pump, the owner, the deep-water lifts 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 model. There are comments on the gradually decreasing pressure of the supplied water due to wear of the screw during long-term operation. However, this is characteristic of any pump of this type.
