WIPO Patent Application WO/2020/180006

The present invention relates to a pump-integrated submersible motor and a pump-integrated submersible motor control device, which are operated by wireless power, wherein, since the submersible motor uses wireless power, elements exposed to the outside are removed and thus waterproofing is increased, and the structure of the submersible motor is simplified.

Water pump

United States Patent 6685448

A pump for pumping water, other liquids, or slurry mixes is described and includes an electric motor or the like positioned above the water to be pumped which has a rotatable pump shaft extending downwardly therefrom which has a driveline shaft connected thereto and which extends downwardly therefrom through a casing. A pump is secured to the lower end of the casing and includes a plurality of vertically spaced-apart pump impellers mounted on a pump shaft which rotate with the driveline shaft. A discharge line extends from the lower end of the pump to a location remote from the pump. Water inlets are provided in the casing below the water line so that the operation of the pump by the electric motor will cause water to be sucked into the interior of the casing and to be drawn into the interior of the pump for discharge from the lower end of the pump.

The invention of an automatic control device for the electric water pump is wireless, which includes two transmitters and a receiver. It is enough to install a transmitter with a high-pressure sensor inside an apartment, villa, or commercial unit or at the end of the line and with a branch by a three-way pipe. Water inlet or by installing a special 1/4 valve and interface hose is filtered everywhere in the water branch in the unit to be installed, and the second part where a receiver is installed next to the water pump by installing a 1.4 water valve after The water meter, before checking, connects the lower device to the low-pressure sensor using an interface hose.

Water pump low-pressure cutoff switch

United States Patent 6552284

A water pump low-pressure cutoff switch comprising a cylindrical housing incorporating an upper water chamber and a lower dry chamber. The water chamber is connected to a water line adjacent to the pump and is formed by a movable circular plate having a sealing means and a centered bypass button post on its top surface. The bottom surface of the movable plate has a pair of cylindrical electrical contacts with flat faces. A fixed plate creating the dry chamber has matching aligned electrical contacts which move apart to break the circuit when a calibrated compression coil spring affixed between the plates expands when predetermined lower water pressure is met.

But the automatic control device of the electric water pump is wireless, without the need for mechanical mechanics and tank, as well as digital automatics, it can control the electric pump by wireless connection and always adjusts the water pressure in the apartment units of each floor, which is proportional to the height of the unit and the power of the pump, without any drop in water pressure.

One of the problems of digital and mechanical automatic in the electrical water pump includes controlling the pressure of water after the pump, which is unable to control the water pressure inside the unit or at the end of the line. By using this invention, which consists of two receiver and transmitter devices, it is enough to install the transmitter with the high-pressure sensor inside a villa apartment, and business unit or at the end of the pipeline. This device will be filtered by installing a branch by a 3-way pipe joint from the entrance pipe or by installing a special 1/4 valve and a connection pipe everywhere in the branch of the pipeline in the unit. After opening the valve inside the unit and dropping the pressure of water less than the quorum, it activates the high-pressure sensor and after transmitting the signal from the transmitter to the receiver installed next to the electrical pump and activating the relay, it causes the water pump to switch on. But in the second part, where a receiver is installed close to the electrical water pump, by installing a 1/4 valve before the check valve and after the water meter, it connects the low-pressure sensor to the lower device by the connection pipe. If the water of the city is cut off, the low-pressure sensor sends a signal that cuts the power of the electric water pump so that the pump does not operate without the water pressure. This invention can be used in homes, offices, and business or industrial units.

As you know, one of the main concerns of humans is the conduction of all kinds of fluids, particularly water. Nowadays, there have been many efforts to design and produce various mechanical devices to conduct liquids to any desired location with ease. An electric pump is one of the inventions that have a set of motive parts such as an electric pump and electric motor that aid to create motion and pressure in fluids. An electric pump can be presented as a mechanical device that causes mechanical force in fluids, and also increases their pressure. The pressure that comes from the pump helps to increase the fluid friction with the body of the pipe, taps, channel wall and conducts the desired fluids. Also, to strengthen the pressure of water or to increase the pressure of water, a device called a water pump (home water pump motor) is used.

One of the problems regarding mechanical and digital automatics in electric pumps is control of the water pressure after the electric pump. The problem is that they can’t control and check the water pressure inside the unit or the end of the line. The available mechanical and digital automatics that control the electric motor in apartment units always have pressure dropping issues and cause errors in the automatics. To solve this problem, you should turn the automatics on and off once or you should vent the electric pump of air. To make the pumps operate automatically and decrease the times of switching on and off and thus to make the pump operate with the lower noise, it is essential to set up a pressure tank with an automatic switch and HUD because the pressurized water that has been stored in the tank causes a constant pressure behind the pipe that leads to a significant decrease in switching on and off frequency, as well as causing an alternate and constant flow of water in the pipes. For this purpose and to solve the above problems, the present device has been designed and manufactured, which has completely solved the mentioned problems.

Solution of problem

In digital and mechanical automatics that are installed on electric water pumps, there have always been issues including the need for adjustment or ventilation and its effectiveness for all units on high floors. In this device, we attempted to design the pressure of water in the apartment units on each floor, which is suitable for the unit height and the pump power, so that the intended unit never has any drop in water pressure. This system functions in a way that if each unit has a separate electric pump to control the switching, the water pressure will be measured by this system based on the water pressure intensity in the unit. In a way that a high water pressure sensor with the ability to regulate the water pressure between 30 psi and 40 psi senses the pressure and commands the voltage connection of the power supply to transmit radio signals to the transmitter. This device is a code learning radio type transmitter that transmits encrypted signals only to receive by the intended receiver.

This system consists of two parts, the first part consists of the transmitter and high-pressure sensor that connects the unit to the sensor by a water pipe or a water hose. This sensor’s micro-switch contacts will be open as long as the sensor is under the pressure of water with a ratio between 30 and 40 psi. As soon as any of the related taps are opened in the unit, the pipe pressure will drop and will be less than the quorum, which causes the sensor contacts to attach to the circuit. This process causes an electrical current to activate the transmitter after the encrypted radio signals are transmitted from the transmitter.

In the second part of the system, the receiver, which can adjust to the MGH433 frequency that comes from any transmitter using a learning micro switch, receives these frequencies and, after recognizing the received signal correctness, activates the 12 V output. After the activation of the 12 V receiver, its output will be connected to the closed electrical contacts of the low-pressure sensor with a ratio of 1 to 5 psi.

In this section, the low-pressure sensor’s task is to be linked to the main branch before the check valve and after the water meter by a hose or pipe to detect any pressure drop when the city water is cut off. As long as this sensor is under the pressure of city water, the micro-switch contacts will be in a closed state and connect the electric current to the 12 V relay. In the path between the relay and the water sensor, there is a 15-sec timer that has two functions. First, if there are a few seconds or a brief moment of disconnection in receiving the signal from the transmitter, the electric pump stays on for fifteen seconds. Second, when the electric water pump is switched on, there is a possibility that the low-pressure sensor disconnects due to the low pressure of water. Therefore, if the sensor is switched off, the electric pump will operate for 15 seconds to resolve the low pressure of the city water.

This sensor stops the electric water pump from switching on when the city water is cut off. Therefore, as long as there is pressure from city water and the transmitter sends electrical signals, the 12 V voltage from the output of the receiver will be connected by the attached electrical contacts of the low-pressure sensor after the 12 V relay timer. In this section, the relay is in charge of switching the 220 V voltage from the power supply of the electric pump. In times when the city water is cut off, this sensor will cut off the micro-switch electrical contacts and prevent the electric pump from switching on without the pressure of city water. By using this device there is no need for any digital or mechanical automatics.

In the spool receiver section, there is a spool in the inlet water pipe, on which a magnet is placed, which causes the spool to go down by reducing or cutting off the city water and causes a large distance between the magnet on the spool and the magnetic sensor, which causes the contact of the magnetic sensor to open, so in this case, the delay timer is activated after one minute, the voltage of 12 volts received from the receiver to the timer is cut off for 15 seconds so that the electric pump does not work without water, if there is the optimal water pressure at the water inlet of Spool, it is in a high position and the magnet on it is placed in front of the magnetic sensor, which causes the connection of the sensor, which causes a voltage of 12 to the timer for 15 seconds. Therefore, only the digital automatic frame and spool can be used as a low-pressure cut-off sensor for the time of city water cut-off, and the automatic digital can be turned into a wireless automatic and the problem of water supply to the upper floors can be solved.

if the magnetic sensor is connected and the signal is received by the 12-volt receiver via D2 to APAMP3, which acts as a delay timer after 15 seconds also, the voltage of 12 volts through D3 saturates transistor T2 and as a result, the output of APAMP1 will be zero. If the magnetic sensor is disconnected, transistor T2 goes from saturation to off due to a decrease in city water pressure, and capacitor C4 starts charging until it reaches 2.3 of the total voltage after one minute, then the output of APAMP1 increases and turns off APAMP2.

In this case, capacitors C5 and R5 act as a 15-second timer and reduce the positive input voltage of APAMP 3 to less than 1.3 volts for 15 seconds after discharging the capacitor and its output is turned off. therefore, transistor T1 is turned off and the relay is disconnected. Which causes the electric pump to shut down. If the transmitter is 12 volts, the receiver is off. In this case, there is a possibility of weak city inlet water, which will cause the magnetic sensor to lose contact.

However, by using C3 and receiving a signal from the transmitter and activating the output of 12 volts, the receiver of the T2 transistor is saturated through capacitor C3 for a moment to discharge capacitor C4 so that the electromotor can check the state of water weakness for one minute.

If the suction of the pump increases the water pressure, the spool rises and connects the sensor and the system continues to operate normally.

To solve the problem of digital control sets that have many problems and errors in apartment units, you can use this wireless system to solve their problem only by changing the range of the control set to an upgraded wireless system can the same RED REL magnetic sensor be used for city water cut-off time, and by upgrading the digital control set to a wireless control set, water supply error problems for units on the upper floors can be solved.
