Hot spring well water pump model

Hot spring well water pump model

According to whether the circulating water is a closed system, the ground source can be divided into closed-loop and open-loop systems. Closed loop systems such as buried coil systems (vertical or horizontal buried pipes) and surface water heat exchanger placement methods. Open loop systems such as extracting groundwater or surface water. In addition, there is a "direct expansion type" that does not use intermediate medium water to transfer heat like the above system, but directly buries a heat exchanger (evaporator) of the heat pump underground for heat exchange.

Common color (when not requested by the customer): Phthalocyanine blue (chlorinated rubber paint) is suitable for unit spraying when working in generally non corrosive water. If the anti-corrosion coating is used in high-temperature environments with corrosion: *: the material of the casting can be changed, such as stainless steel, tin bronze, etc. Secondly, if the corrosion is not particularly severe, the anti-corrosion coating epoxy topcoat can be applied, which can increase the service life of the unit after applying the anti-corrosion coating. The submersible pump has a compact structure, and during operation, only the submersible pump needs to be placed outside the water to start working. It is easy to install and disassemble, and convenient to move. Due to its simple structure, small size, and convenient use, it has achieved agile growth with an integrated motor and water pump, which can operate underwater safely and reliably. There are no special requirements for well pipes and water lifting pipes (i.e. steel pipe wells, ash pipe wells, soil wells, etc. can all be used; under pressure permission, steel pipes, rubber hoses, plastic pipes, etc. can all be used as water lifting pipes).

According to the different relative positions of the pump and motor, submersible pumps can be divided into upper pump and lower pump types. The upward pump type submersible pump has the pump on top and the motor on the bottom. This structure greatly reduces the radial size of the pump, so it is mostly used for well submersible electric pumps and small operation submersible electric pumps. The submersible pump motor is located above and the pump is located below, and it is divided into two types: internal and external. The liquid transported by the submersible electric pump with a built-in pump first passes through the annular flow channel surrounding the motor to cool it before flowing out of the pump pressure outlet. This type of pump does not have to worry about the motor heating up even when it is close to the drainage and suction tank, so its application range is increasingly expanding. The externally mounted submersible electric pump discharges liquid directly from the pressure chamber behind the impeller or the outlet of the guide vane body, and the motor is also cooled by the pumped liquid. Due to its ability to work in shallow liquids, the submersible pump structure is commonly used in working surfaces, especially as the main structural type for large-diameter submersible pumps. The mechanical seal of the submersible pump is located in the high-pressure zone of the outlet water flow, where the higher the head, the higher the water pressure. Depending on the characteristics of its impeller structure, the submersible pump may have different applications. Open or semi open impeller: made of wear-resistant materials, equipped with adjustable guide vanes and filter screens. Widely used in construction sites, caves, harbors, factories, ships, etc. for water supply and drainage or water spraying, it can pump liquid media containing abrasives such as clay, sand, gravel, drill cuttings, etc. Mobile structure that can be started when placed in water, meeting special requirements such as high flow rate, high head, limited space, or explosive environments. Non clogging closed channel impeller has good reliability and high efficiency, mainly used for pumping sewage and mud in urban pumping stations and sewage treatment plants, pumping cooling water, wastewater, corrosive media, etc. in industrial processes, and continuous drainage in construction sites and large factories. Very suitable for pumping media containing long fibers and large solid particles. Installed in small and simple pump stations, it can be hidden underground, and the pump can be quickly and easily installed on guide rails or ropes and lowered into the pump pit. The open impeller is equipped with an S-shaped cutter, which has functions of pumping, cutting, and mixing. Good reliability and high efficiency. Mainly used for pumping liquid manure in agriculture, it can crush dry solids, straw and other long fiber materials. The spiral impeller inlet allows for the suction of thick manure into the pump, with four specifications available. Compact structure, installed on the guide rails in the manure tank or in the storage tank, can be used in conjunction with a submersible mixer to use multi blade closed impellers, cast in cast iron or stainless steel, with single-sided or double-sided (double suction) water inlet. Especially suitable for agricultural sprinkler irrigation and various industrial applications, such as supplying clean water, process water, spraying and cooling water, etc. It can meet the needs of high head and large flow rate, with a flow rate of 2000m3/h and a head of 110m. It is suitable for pumping clean water or lightly polluted water, and has multiple specifications and structural types. Strong functionality, high reliability, easy installation and maintenance. Compact and simple structure, no special installation required, just drop onto the protruding shoulder of the housing seat. Open impeller with a shredding device attached at the inlet, composed of chromium alloy and stainless steel. Especially suitable for pressure sewage systems, it can be transported away through pipes with a diameter of only 40mm.

Stainless steel high-temperature resistant geothermal submersible pump, hot water submersible pump

（1） Product Usage and Main Features

Hot submersible pumps are suitable for geothermal wells and are used to extract geothermal water. Geothermal energy is a cheap and clean energy source widely used in heating, medical treatment, bathing, aquaculture, planting, industrial and agricultural production, services, and other fields.

The series of hot submersible pumps work in geothermal wells, with advantages such as heat resistance, corrosion resistance, high efficiency, energy saving, and easy installation and maintenance. It is a replacement product for geothermal water extraction equipment.

（2） Usage conditions

1. A three-phase AC power supply with a rated voltage of 380V ± 5% and a frequency of 50Hz ± 1% should ensure that the rated voltage at the motor terminal is within the allowable deviation range of the rated voltage.

3. The control cabinet must have basic protection functions such as short circuit, phase loss, overcurrent, overload, etc., and ensure that the setting value is adjusted to a stable and sensitive position during installation. This step is very important and requires professional technicians to debug it correctly.

3. The motor is a flushing type, and before installation, the motor chamber must be filled with distilled water (or clean water).

4. The first stage impeller of the water pump should penetrate at least 3 meters below the dynamic water level, the electric pump unit should not penetrate more than 70 meters below the static water level, and the distance from the bottom of the motor to the bottom of the well should not be less than 5 meters.

5. When selecting a model, the diameter of the well should match the model of the pump. It is important to avoid using a pump with a diameter that is too small for a large diameter well, as this is not conducive to the heat dissipation of the motor.

6. The water temperature should not exceed 120 ℃.

7. The water does not contain any oily substances.

Material Description

1. Impeller: cast iron HT200 or tin bronze (various grades) such as ZCuSn3Zn8Pb6Ni1

2. Pump casing: cast iron HT200 or stainless steel such as 2Gr13.304

3. Pump shaft: Cold drawn steel chrome plated, or stainless steel 2Gr13 (quenched and tempered at 1050 ℃ to enhance torque)
