Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water-cooled pump technology, and in particular relates to a water-cooled pump with a scale adsorption device. Background Technology
[0002] With social progress and rapid urbanization, the building water supply industry has developed rapidly. Water pumps are the core equipment of water supply units, and water pump technology is being updated and upgraded rapidly. Today, water-cooled motors for pumps are emerging in the market like mushrooms after rain. Water-cooled motors for pumps use cooling channels to introduce the medium pumped by the pump into the motor, thereby cooling the motor.
[0003] The medium pumped by the water pump inevitably contains different types of impurities. When these impurities enter the motor, they may clog the cooling channels. At the same time, scale will gradually form in the cooling channels of the water-cooled motor during long-term use, causing blockage and gradually weakening or even eliminating the cooling effect of the water flow. Ultimately, this will prevent the motor from cooling down, and prolonged use at high temperatures will burn out the motor bearings, rendering the entire motor unusable. In addition, scale itself will also corrode the channel material. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a water-cooled pump with a scale adsorption device, which reduces the flow of impurities in the cooling channel, reduces the scale formation speed, and further removes the scale already adsorbed on the surface of the channel.
[0005] The technical solution adopted by this utility model to solve its technical problem is: to provide a water-cooled pump with a scale adsorption device, including a water pump and a motor. The motor is provided with a cooling channel communicating with the cavity of the water pump. It also includes a pre-filter valve and a rotary valve. The pre-filter valve is located at the water inlet of the cooling channel. The rotary valve is provided in the cooling channel. One end of the rotary valve is located in the cooling channel and is connected to a take-up device. A pull line is coiled on the surface of the take-up device. The pull line is connected to a cleaning ball. A scraper is provided on the outer periphery of the cleaning ball.
[0006] Preferably, the pre-filter valve is located in the cooling channel, with one end being a hollow filter valve body and the other end having a pre-filter screen communicating with the filter valve body.
[0007] Preferably, the pre-filter is embedded in the filter valve body.
[0008] Preferably, the surface of the filter valve body is provided with external threads that match the cooling flow channel.
[0009] Preferably, the rotary valve includes a rotary valve body, and the rotary valve body is provided with an electrically controlled valve stem for electrically controlling the rotation of the rotary valve.
[0010] Preferably, a pre-cooling pressure gauge is provided upstream of the cooling channel, and a post-cooling pressure gauge is provided downstream of the cooling channel. The pre-cooling pressure gauge and the post-cooling pressure gauge are connected to the control cabinet, and the control cabinet controls the rotation of the electrically controlled valve stem according to the pressure data.
[0011] Preferably, the cleaning ball has a limiting piece at the end away from the rotary valve, which is bound by a limiting line, and the limiting line is connected to the pull line.
[0012] Preferably, a number of cleaning balls are arranged in series on the pull line.
[0013] Preferably, the scraper extends toward the water inlet.
[0014] Preferably, the cleaning ball contains a sintered activated carbon filter element.
[0015] The beneficial effects are as follows: This utility model can initially filter impurities entering the cooling channel by setting a pre-filter valve at the inlet of the cooling channel. The pre-filter valve is detachable for easy cleaning and can effectively prevent clogging. A rotary valve is also set in the cooling channel. One end of the rotary valve is connected to the cleaning ball through a pull line, and the cleaning ball and the scraper on its surface are controlled to move back and forth in the cooling channel, so as to adsorb the scale that has not adhered to the wall and scrape and remove the scale that has adhered to the wall.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
[0022] like Figure 1 As shown, this utility model provides a water-cooled pump with a scale adsorption device, including a water pump A and a motor B. The motor B has a cooling channel 7 communicating with the cavity of the water pump A. It also includes a pre-filter valve 2 and a rotary valve 1. The pre-filter valve 2 is located at the inlet of the cooling channel 7. The rotary valve 1 is located in the cooling channel 7. One end of the rotary valve 1 in the cooling channel 7 is connected to a take-up coil 1.3. A pull wire 4.1 is coiled on the surface of the take-up coil 1.3. The pull wire 4.1 is connected to a cleaning ball 4. The cleaning ball 4 has a scraper 4.5 on its outer periphery.
[0023] In a kind of Figure 2 In the specific embodiment shown, the rotary valve 1 includes a rotary valve body 1.1, and the rotary valve body 1.1 is provided with an electrically controlled valve stem 1.2 for electrically controlling the rotation of the rotary valve 1, so as to retract and extend the pull wire 4.1 as needed, and control the movement of the cleaning ball 4 in the cooling channel 7.
[0024] In a kind of Figure 3 In the specific embodiment shown, the pre-filter valve 2 is located within the cooling channel 7, with one end being a hollow filter valve body 2.1 and the other end having a pre-filter screen 2.2 communicating with the filter valve body 2.1. The pre-filter screen 2.2 is embedded in the filter valve body 2.1. The surface of the filter valve body 2.1 has external threads that match the cooling channel 7, allowing the pre-filter valve 2 to be independently installed and tightened, ensuring safety and reliability.
[0025] A pre-cooling pressure gauge 3 is provided upstream of the cooling channel 7, and a post-cooling pressure gauge 6 is provided downstream of the cooling channel 7. The pre-cooling pressure gauge 3 and the post-cooling pressure gauge 6 are connected to the control cabinet 5. The control cabinet 5 controls the rotation of the electric control valve stem 1.2 according to the pressure data.
[0026] A plurality of cleaning balls 4 are arranged in series on the pull wire 4.1. The number of cleaning balls 4 and the length of the pull wire 4.1 can be arranged as needed according to the specific form of the motor B and the position and extent of the structure within the cooling channel 7. In a certain way... Figure 4In the specific embodiment shown, the cleaning ball 4 is provided with a limiting piece 4.3 tied by a limiting line 4.2 at one end away from the rotary valve 1. The limiting line 4.2 is connected to the pull line 4.1, and the length of the pull line 4.1 and the position of the limiting line 4.2 are used to control the farthest position of the cleaning ball 4 in the cooling channel 7.
[0027] In one specific embodiment, the scraper 4.5 extends toward the water inlet, such as... Figure 1 The counterclockwise flowing cooling water is scraped by the downward-facing, unopened arc-shaped scraper blade 4.5, which facilitates the water inlet of the cooling channel 7 to carry the cleaning ball 4 to the predetermined position. At the same time, when it retracts, it can also scrape off the scale attached to the channel.
[0028] In a kind of Figure 4 In the specific embodiment shown, the cleaning ball 4 is equipped with a sintered activated carbon filter element 4.4, which can adsorb scale that is not attached to the wall.
[0029] In one specific embodiment, the inner wall of the cooling channel 7 is coated with a chemical coating to prevent scale buildup.
[0030] The main operation of this invention is accomplished by the cleaning ball 4. At the start of operation, the scraper 4.5 of the cleaning ball 4, driven by the water flow, reaches a predetermined position within the motor's B flow channel. The internal sintered activated carbon filter 4.4 adsorbs some impurities from the water. When the operating time is prolonged, and the pressure gauge readings before and after cooling differ significantly, it indicates scale buildup inside the motor. The control cabinet 5 then controls the electric control valve stem 1.2 of the rotary valve 1 to rotate the retractor 1.3, retracting the cleaning ball 4. During retraction, the scraper 4.5 of the cleaning ball 4 scrapes away the scale adhering to the flow channel. After the cleaning ball 4 is fully retracted, the control cabinet 5 controls the electric control valve stem 1.2 of the rotary valve 1 to reverse direction, releasing the retractor 1.3 and pulling up the cable 4.1. The scraper 4.5 of the cleaning ball 4 will then be driven by the water flow back to its predetermined position within the motor's B flow channel. This device removes impurities and scale from the cooling water inside water-cooled motors through physical adsorption, scraping, filtration, and chemical coating, reducing motor corrosion and damage caused by scaling. It is highly practical.
