High temperature resistant water pump

I. Product overview Hot water pump, hot spring pump, high temperature resistant hot water deep well pump, submersible pump

        QJ series hot water submersible pump, designed to pump high temperature liquid, consists of YQS submersible motor and QJ submersible pump. The pump parts are precision manufactured by HT200 material. It adopts centrifugal single-suction multi-stage pump body structure with built-in check valve and suction filter. The impeller is fixed on the pump shaft by a uniform key and equipped with pump shaft protection bushing. . The submersible motor uses water-lubricated bearings, and the upper end is equipped with a sand blaster and a skeleton oil seal to prevent mud and sand from entering the motor. This series of products has the characteristics of compact structure, safe and reliable operation and long service life.

        The flow rate can reach 5 to 500 tons per hour and the lift can reach 800m

        Second, the cost-effective high-power hot water deep well pump main use

        Groundwater hot water wells extract water and extract underground hot springs; can withstand high temperature of 80°

        Residential heating, bathing center circulating hot water, geothermal development and utilization, heating system

        Enterprises use geothermal energy to generate electricity and extract underground hot water. According to different well diameters, we have different specifications for users to choose.

        Third, the application conditions

        Pumping medium: high temperature liquid similar to clean water with a solid content of not more than 0.02%

        Medium temperature: deep well heat pump around 80 °C

        Media pH: 3 to 10

        Power requirements: frequency 50Hz, 60Hz (customizable), rated voltage 380V, 660V

        Fourth, technical parameters

        Flow range: 5 to 500 cubic meters / hour

        Head range: 20 to 600 meters

        Power range: 3 to 500 kW (secondary speed motor)

        Speed: 2850 rpm (secondary speed motor)

        Optional material: HT200

        V. Use and characteristics of the product:

        QJ and QJR series products are important equipment for deep well water lifting. When used, the whole unit sneak into the water to extract groundwater to the surface, which is domestic water, mine rescue, industrial refrigeration, farmland irrigation, seawater lifting, ship loading, and can also be used. Fountain landscape. The hot water submersible pump can be used as a hot spring bath, and the residential area can be used as a geothermal circulation pump when used for geothermal heating.

        Sixth, hot water well submersible pump precautions

        1. This product is a clean water pump. It is strictly forbidden to pump muddy water and corrosive water.

        2. Determine the temperature of the well water to ensure that it does not exceed the temperature limit of the hot water pump.

        3. Qualified power supply, cable and starting equipment (such as air switch and auto-decompression start-up box) must be used as required. The starting equipment should have short-circuit, phase-failure, overload and other protection functions. Under the normal operation of the electric pump, The protective device should not be operated.

        4. Installation and use of electric pump must be reliably grounded. It is forbidden to wet the wet foot to push the electric brake. Before installing and repairing the electric pump, the power must be cut off. The place where the electric pump is used should be set with the obvious signboard to prevent electric shock.

        5. Before the lower well, the inner cavity of the motor must be filled with distilled water or non-corrosive clean cold water. Tighten the water supply and drain bolts. When the electric pump is tested on the ground, it must be filled with water to lubricate the rubber bearings in the pump cavity. Seconds, see if the steering is the same as the steering indication. Pay attention to safety when the electric pump is upright, and prevent it from turning to hurt people.

        6. Strictly use the head and flow range specified by the electric pump to prevent the high flow of the lift or the high axial force of the lift, so that the thrust bearing and other parts are sharply worn, and the motor is overloaded and burned.

        7. After the electric pump is down, the insulation resistance of the motor to ground should be no less than 100 megohms. After starting, it is necessary to observe the voltage and current regularly, check the insulation of the motor winding, and meet the requirements.

        8. Under the premise of ensuring the technical performance of the submersible pump, the specific specification data such as the number of submersible pumps may be changed due to technical improvements without prior notice. Please refer to the electric pump nameplate data.

        9. When the electric pump is stored, the motor memory water should be drained to prevent the motor from freezing in winter.
