UK GRIMM Submersible pumps for imported wells summary:
The import of submersible electric pump is an energy-saving product design according to the international standard, widely used in agricultural irrigation, industrial and mining enterprises for drainage and plateau and mountainous areas, drinking water.
The pump is composed of submersible pump and submersible motor. It works underwater. The utility model has the advantages of simple structure, small size, light weight, convenient installation and maintenance, safe operation, reliability, high efficiency, energy saving, etc..
Well with submersible pump heat is directly connected with the well heat circle of three-phase asynchronous motor, the assembled heat submersible pump, hot water temperature can reach 100 DEG C, is an effective tool to sneak into the wells, extraction of geothermal water; geothermal energy is one of the cheapest, most clean, inexhaustible new energy, is widely used in many aspects of heating, bathing, medical, breeding, cultivation, agriculture, industrial and mining enterprises, entertainment services, health care facilities etc.. The utility model has the advantages of simple pump structure, reliable operation, no noise, good performance, high unit efficiency, convenient installation and maintenance, and heat resistance. Anti corrosion, anti-aging and many other characteristics, it is the latest product of geothermal water extraction.
UK GRIMM Submersible pumps for imported wells structure description:
1.The submersible pump for the well is centrifugal or mixed flow. The water lubricated bearing is adopted. The coupling of the motor and the motor is connected by a rigid coupling. The pump impeller is driven by the motor to rotate to generate centrifugal force, so that the liquid energy is increased, and the water pumping is carried out by the diversion action of the pump shell. A non-return valve body is arranged at the upper end of the water pump to prevent the working parts of the water pump from being damaged by the backflow of water in the water pipe when the electric pump is stopped. The valve is provided with a drain hole of the water in the pipeline can be slowly discharged, to prevent the winter frost crack pipe. (Note: the low lift submersible pump does not have a non-return valve body)
2.The motor is closed water filled wet structure. The motor stator winding adopts water (heat resistant) polyethylene insulated, nylon sheath multilayer structure (heat resistant) electromagnetic wire. Guide bearings and thrust bearings are made of water lubricated material. The motor is filled with clean water to cool the motor and lubricate the bearings. The motor is arranged at the bottom of the pressure adjusting membrane, to adjust the motor temperature rise caused by the expansion and contraction of the water pressure difference. The upper end of the motor is provided with a sand prevention mechanism to prevent mud and sand from entering the interior of the machine.
3.Pipeline part: used to connect the electric pump, lifting it in the well, and transport the water to the ground. Mainly by short water pipe, water pipe, elbow, plywood and other components. The short output pipe is a connecting transition component between the water delivery pipe and the electric pump. The pipe is installed at the wellhead to change the direction of the flow. The clamping plate is lifting and fixing the output pipeline during the installation of the electric pump.
UK GRIMM Submersible pumps for imported wells conditions of use:
(1) rated frequency is 50 Hz, the motor end rated voltage should be guaranteed to be 380 + 5% volts three-phase AC power supply (if the user voltage is 660 volts, special orders).
(2) the transformer load power should not exceed 75% of its capacity.
(3) when the transformer is far from the well, the voltage loss of the transmission line should be considered. The motor with power greater than 45KW requires that the distance from the transformer to the wellhead is not more than 20 meters. For high lift submersible pump, the transmission line is longer, must consider the pressure drop loss, transmission line cable specification requirements specifications than the two grade. The transformer output voltage is 400V-440V by using single transformer supply.
2.Water quality requirements:
(1) General non corrosive clean water.
(2) The sediment concentration in water is not more than 0.01% (mass ratio).
(3) PH value is within the range of 6.5-8.5.
(4) The content of chloride ion in water is not more than 400 mg / liter.
(5) Hydrogen sulfide content is not more than 1.5 mg / liter.
(6) The submersible pump for the well is not over 20 centigrade. Heat resistant submersible pump for water temperature is not higher than 100 degrees.
(7) Contains no oil.
Upright, smooth, must not have the bulge or the well pipe dislocation phenomenon, the well bore diameter is not less than the corresponding frame number.
