Description

[0001]Description of the invention The title of the invention Submersible water pump with a large impeller inside the tank without the need to take air to transfer and empty water Technical background of the related invention Electricity and electronics, mechanics Technical problem and stating the objectives of the invention Consumers of high-flow water transfer pumps use common pumps in the market, which are the same water transfer series using centrifugal technology. All pumps benefit from 2800 to 3000 revolutions per minute, and this Causes high depreciation in the pump, and the most important common problems that can be mentioned are as follows. 1- High energy consumption due to continuous water suction and water pressure to the pump outlet (for example: to move 200 liters per second with centrifugal pumps, around 37 kilowatts of energy must be supplied. 2- When a piece of stone or cloth or plastic passes into the propeller, the propeller will be seriously damaged and the coil of the electric motor will burn. 3- In the current series of pumps, due to high-speed depreciation of pumps that are floating in water, the sealing equipment wears out at a high speed, and water quickly enters the coil from the shaft and causes the loss of the electromotor coil. And if it is snailed and out of water, in the same way, the sealing equipment will break down at a faster rate and cause leakage from around the shaft and water splashing on the electric motor. In the invention, the vertical pump is made with the following objectives: 1- The pump has an electric motor between 750 and 1480 revolutions per minute according to the required flow rate from 50 liters per second to 2000 liters per second. The higher the flow rate, the lower the impeller turns, and this causes it to have low depreciation. 2- The pump impeller is an OPEN impeller series that the distance between the blades of the propeller is more than five centimeters and pieces of cloth, plastic and small stones pass through the pump impeller and do not harm the pump. 3- The impeller is designed in a way in this system of pumps that does not require high energy to transfer water (for example: 9 kilowatts of energy is needed to transfer and move water at the rate of 200 liters per second, which is the same amount in the series of pumps The centrifugal current is around 37 kW. 4- In the invention of the pump, the impeller is always in the water and there is no need for a one-way valve, and as soon as the pump is turned on, the water comes out of the pump outlet. 5- In the invention of the pump, a moisture sensor is built in, which cuts off the electricity as soon as moisture enters, which is caused by the failure of the sealing parts, and does not cause financial or life damage. According to the mentioned materials, the purpose of the invention is to make a type of pump with high water transfer and low energy consumption and low depreciation compared to the current common pumps, which is one of its uses in the fisheries and fish farming sector. Description of the state of prior knowledge and history of developments related to the claimed invention In common pumps in the world, for transferring and moving water, Close series pumps (floating pumps, etc.) are used in a centrifugal way, which requires 2800 to 3000 revolutions to be able to suck and discharge water. Also, the high wear and tear of the pump is caused by the high speed of the pump, and it also includes centrifugal pumps with high energy consumption. The consumer will have to pay a high cost of energy for operation and the failure of the impeller is due to the entry of small objects into the impeller and finally the dangers of water and moisture infiltration into the coil of the electric motor of the pump. In this case, no appreciable progress has been made in the field of water transfer with high flow. Among the similar inventions, this invention does not exist. 1.

(This pump is also different from our patented pump because it uses a centrifugal system.) Providing a solution for the existing technical problem along with an accurate and sufficient and integrated description of the invention The water pump goes completely into the water and is waterproof, which has an electric motor that is proportional to the water flow rate of the pump from 750 to 1480 revolutions per minute. A water transfer propeller is installed at the end of the shaft coming out of the electric motor That the entire equipment, including electric motor and propeller, is placed inside the water The coil and rotor of the electric motor is inside a completely waterproof chamber, and the end of the shaft is inside a bearing and a round bottom, and the end of the motor shell is placed inside the bearing bowl, and the bottom of the bearing bowl is the door at the end of the motor, and the end of the shaft does not come out of the bowl. (The round bottom bearing repels the pressure caused by the transfer of water to the upper surface) A motor door is placed on the upper part of the motor shell, from which the upper part of the shaft comes out and is completely sealed and protects the water from entering the electric motor shell. Two bearings are placed in the same part, and the bearings are placed inside the engine shell, and then hydraulic oil is poured into the engine shell, and the bearings are in contact with the oil inside the engine core. After placing the upper door of the motor shell, a bowl-shaped chamber is placed on the door, through which the motor shaft passes and is completely sealed. In which the hydraulic oil chamber is poured and in order to separate the chamber oil as well as the possible entry of water into the electro motor shell, a mechanical seal passes through the shaft and is connected to the bottom of the chamber. After placing the second chamber on the engine shell, another chamber named the third chamber is placed on the second chamber and compared to the second chamber, it is completely watertight as the continuation of the shaft passes through the middle of the chamber and in the upper part of the chamber, which is under the roof of the chamber. A mechanical seal is placed to prevent the entry of water and also a humidity sensor is placed in the chamber (as soon as a drop of water enters and before it enters the second chamber that is installed on the electric motor, the sensor works and the electric current is separated from the electric motor of the motor and does not cause an accident) After the third chamber, the shaft continues to exit and enters the water, and also, after the exit of the shaft, a mechanical seal is installed exactly above the third chamber, outside the chamber and into the water to help the second mechanical flood in the third chamber and prevent the possible entry of water into the third chamber where the humidity sensor is located. And after the output of the shaft, the water transmission propeller is connected and the propeller is placed inside a cylindrical housing, the inner diameter of the cylinder from the beginning to the end is 2 mm larger than the diameter of the propeller. Due to the fact that there must be a distance for water suction from under the propeller, a tubular casing with five columns around it is installed on the electric motor, which does not need to be sealed, and then the propeller housing is installed on it. The reason for the five mentioned columns is that the lower part of the impeller is completely open for water suction and also have enough endurance to connect the propeller housing. Inside the propeller housing, which is like a tube, half of its height is connected to the tube as a shield from the inside, from the middle of which the guide bushing at the end of the shaft is installed to the center of the shield. The longitudinal height of the shield inside the impeller housing is about ten centimeters, and these shields installed inside the impeller housing make the water not go out in a circular way when it exits the pump and slowly exits from the outlet pipe. Finally, by starting the engine, the propeller installed at the end of the electric motor shaft will rotate and the propeller will transfer the water from its lower part to the top, and a pipe can be installed in the upper part of the propeller and the water will be transferred to the desired place.
