Description

Technical Field

[0001] The invention belongs to the technical field of water pumps, in particular to a water pump capable of increasing lift. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0003] In the cement production field, variable frequency water pumps, as the core equipment for fluid transportation, are mainly used in the water supply link. Variable frequency water pumps are equipment that uses variable frequency technology to adjust the speed of the water pump. They are mainly used for energy saving and regulating water flow, while also increasing or decreasing the head. Since water supply is mostly continuous, variable frequency water pumps continuously generate heat. Currently, the motors of variable frequency water pumps mostly rely on their own cooling fans for air cooling. When the ambient temperature is high and the motor speed is low, the heat dissipation performance will decrease, resulting in the heat generated during the operation of the motor cannot be discharged in time. Continuous accumulation can easily cause the motor to overheat, which will not only affect the operating stability of the water pump, but also increase the risk of failures such as motor burning and bearing damage.

[0008] In the above technical solution, preferably, the air guide assembly includes a three-way pipe, which is connected to the front and back of the transmission box, and the top of the transmission box is fixedly connected to an air guide cylinder. The top of the three-way pipe is connected to the surface of the air guide cylinder, and the top of the rotating rod is fixedly connected to the fan blade. The top of the air guide cylinder is connected to an air intake pipe, and the end of the air intake pipe away from the air guide cylinder is connected to the top of the protective cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention drives the operation of components such as the turbine and gear pump through the power of water flow, and can achieve the coordinated circulation of coolant and air without additional energy consumption. The refrigeration plate continuously cools the coolant through the fixed sleeve, and the spiral tube uses the low-temperature coolant to efficiently cool the air entering the transmission box, ensuring that the low-temperature air flows to the energy-saving motor inside the protective sleeve, thereby improving the heat dissipation efficiency; it can stably conduct heat under the working conditions of high ambient temperature and low motor speed to avoid heat accumulation. At the same time, the closed circulation path can isolate the external high temperature and dust interference, can stably control the motor temperature, improve the stability of water pump operation, and reduce the risk of failures such as motor burning.

[0015] Furthermore, when there is a certain humidity inside the protective cover, the air is easily condensed due to the sudden drop in temperature after being cooled by the spiral tube. At the same time, impurities may appear in the device due to mechanical wear. If these moisture and impurities come into contact with the energy-saving motor, it will cause the insulation of the energy-saving motor to decrease and the bearings to be aggravated by impurity wear. By setting up a cleaning component, the air can be dehumidified and impurities in the air can be intercepted at the same time, avoiding the impact of moisture and impurities on the energy-saving motor and ensuring the long-term stable operation of the internal circulation system.

[0016] Furthermore, although the filtered air has been cooled, relying solely on the thrust circulation of the energy-saving motor's own cooling fan may cause the air flow rate between the protective cover and the transmission case to decrease due to the resistance of the filter component, resulting in local air stagnation. The cooled low-temperature air cannot be efficiently transported to the core heating area of ​​the energy-saving motor, affecting the heat dissipation effect. However, through the structural design of the three-way pipe, air guide cylinder, fan blades and air intake pipe in the guide component, the fan blades are actively driven by the rotating rod to blow air, and the air is directed into the air intake pipe with the help of the air guide cylinder, thereby enhancing the air circulation power, preventing airflow blockage caused by the filter component, ensuring that the cooled air stably enters the interior of the protective cover, and realizing continuous and efficient cooling of the energy-saving motor.

The overall structure is driven by the kinetic energy of water, and a coolant circulation loop can be formed without additional energy consumption, providing continuous power for the heat exchange system, and enhancing heat dissipation stability and energy saving.

[0027] like Figure 5 As shown, a liquid adding pipe 6 is provided on the left side of the top of the transmission box 52 , the bottom end of the liquid adding pipe 6 passes through the interior of the spiral tube 572 , and a sealing sleeve 7 is threadedly connected to the top of the surface of the liquid adding pipe 6 .

[0028] Specifically, the combined design of the liquid adding pipe 6 and the sealing sleeve 7 can conveniently add coolant to the interior of the spiral tube 572 and the fixed sleeve 56. The threaded sealing sleeve 7 can ensure the sealing of the pipeline after liquid addition, preventing coolant leakage or external air and impurities from entering the circulation system.

[0029] like Figure 3As shown, the guide assembly 59 includes a three-way pipe 591, which is connected to the front and back of the transmission box 52. The top of the transmission box 52 is fixedly connected to an air guide cylinder 592. The top of the three-way pipe 591 is connected to the surface of the air guide cylinder 592.

The end of the air intake pipe 594 away from the air guide cylinder 592 is connected to the top of the protective cover 51.

[0030] Specifically, the guide component 59 generates a directional airflow in the air guide cylinder 592 by using the fan blades 593 driven by the rotating rod 584, and efficiently introduces the low-temperature air into the interior of the protective cover 51 through the air inlet pipe 594, forming a directional airflow circulation path; the linkage design of the fan blades 593 and the rotating rod 584 uses the water flow power to provide stable wind pressure, avoid air stagnation, and ensure that the cooled air flows continuously and accurately to the heat dissipation area of ​​the energy-saving motor 1.

[0031] like Figure 7 As shown, a filter assembly 8 is provided inside the tee pipe 591, and the filter assembly 8 includes a filter cartridge 81, which is provided inside the tee pipe 591.

[0032] Specifically, a threaded hole is provided at the bottom of the filter cartridge 81, and the filter cartridge 81 is threadedly connected to the surface of the threaded rod 83 through the threaded hole. The silica gel drying particles 82 can adsorb and dehumidify the moisture in the circulating air, and the filter cartridge 81 can intercept impurities in the air; the threaded installation sleeve 84 is convenient for the disassembly, assembly and replacement of the filter cartridge 81, and can ensure the sealing fit with the three-way pipe 591, effectively preventing humid air and impurities from entering the subsequent airflow path. At the same time, the silica gel drying particles 82 can be replaced through the threaded hole.

[0033] like Figure 7 As shown, a moisture-absorbing sponge 9 is fixedly connected to the bottom of the inner wall of the mounting sleeve 84 , and a sealing ring 10 is fixedly connected to the top of the surface of the filter cartridge 81 , and the surface of the sealing ring 10 contacts the inner wall of the tee pipe 591 .

[0034] Specifically, if condensation occurs inside the transmission box 52, the condensation will fall into the interior of the mounting sleeve 84 through the transmission box 52 and the three-way pipe 591. The moisture-absorbing sponge 9 stores the water to prevent the accumulated water from affecting other components. The sealing ring 10 can seal the gap between the filter cylinder 81 and the three-way pipe 591 to prevent unfiltered air from entering the air guide cylinder 592, thereby reducing the risk of moisture in the energy-saving motor 1.

[0035] like Figure 2As shown, a metal sound-absorbing plate 11 is fixedly connected to the inside of the protective sleeve 51 , an annular sound-absorbing cotton 12 is fixedly connected to the top of the inner wall of the protective sleeve 51 , and the surface of the annular sound-absorbing cotton 12 is fixedly connected to the inner wall of the protective sleeve 51 .

[0036] Specifically, the metal sound-absorbing plate 11 and the annular sound-absorbing cotton 12 can absorb the noise diffused to the inner wall of the protective sleeve 51 , and the two work together to significantly reduce the noise generated by the operation of the energy-saving motor 1 and prevent the noise from affecting the surrounding environment.

[0037] like Figure 3 and Figure 9 As shown, a rubber ring 13 is fixedly connected to the top of the drain pipe 4, the inner wall of the rubber ring 13 contacts the surface of the rotating rod 584, and a top plate 14 is fixedly connected to the right side of the top of the outer cylinder 573, and the top of the top plate 14 is fixedly connected to the top of the inner wall of the transmission box 52.

[0038] Specifically, the rubber ring 13 can seal the gap between the rotating rod 584 and the drain pipe 4 to prevent water or moisture in the drain pipe 4 from penetrating into the interior of the transmission box 52; the top plate 14 can provide stable support for the outer cylinder 573, thereby enhancing the prevention of displacement of the outer cylinder 573 during coolant circulation or equipment vibration, thereby reducing potential fault hazards.

[0039] like Figure 2 As shown, the interiors of the exhaust pipe 53 and the intake pipe 594 are fixedly connected with a fixing ring 15, and the surface of the fixing ring 15 is fixedly connected with a sealing plate 16 via a spring hinge, and the side of the sealing plate 16 close to the fixing ring 15 is in contact with the surface of the fixing ring 15.

[0040] Specifically, the exhaust pipe 53 and the fixed ring 15 in the intake pipe 594 cooperate with the sealing plate 16 connected by the spring hinge to form a one-way conduction structure: when the airflow flows in the forward direction, the sealing plate 16 is pushed open to allow air to pass through; when the airflow stops or reverses, the spring hinge drives the sealing plate 16 to reset and fit the fixed ring 15, blocking the channel. This design can ensure that the internal circulating air flows in a directional manner according to the set path, and can be closed when the energy-saving motor 1 is not in use to prevent moisture that may exist inside the transmission box 52 from affecting the energy-saving motor 1.

[0041] The working principle and use process of the present invention: First, start the energy-saving motor 1 and the cooling fins 55. When the energy-saving motor 1 drives the pump head 2 to operate, water flows through the drain pipe 4 and drives the turbine 583 to rotate. The turbine 583 drives the rotating rod 584 to rotate through the commutator 581. The rotating rod 584 drives the gear pump 586 to work through the gear ring 585. The gear pump 586 circulates the coolant inside the spiral tube 572 and the fixed sleeve 56 through the connecting pipe 574. The cooling fins 55 continuously cool the coolant through the fixed sleeve 56. The cooling fan of the energy-saving motor 1 will blow air downward to cool the surface. The air after heat exchange enters the interior of the transmission box 52 through the exhaust pipe 53. The spiral tube 572 guides the air and cools the air through the low-temperature coolant. The cooled air enters the interior of the air guide tube 592 through the three-way pipe 591. The rotating rod 584 drives the fan blades 593 to rotate, and the fan blades 593 push the airflow upward, so that the cold air enters the interior of the protective cover 51 stably through the air inlet pipe 594 to cool the energy-saving motor 1 and exchange heat, thereby achieving the effect of internal circulation cooling.
