Description

Technical Field

[0001] The invention relates to the technical field of hot water circulation pumps, and in particular to a safe and stable high-temperature resistant hot water circulation pump system. Background Art

[0002] A hot water circulation pump is a pump device used to maintain the pressure and temperature of a hot water system. The basic function of a hot water circulation pump is to keep the water flowing in the hot water system and avoid heat loss caused by long-term standing. It generates centrifugal force through the high-speed rotation of the internal impeller to promote the circulation of water, or converts the energy of the liquid through volume changes to achieve the purpose of conveying liquid. The hot water circulation pump has the characteristics of high efficiency, energy saving, low noise, and compact design, which is easy to install and maintain. For example, the IRG type single-stage single-absorption hot water pipeline pump adopts a vertical structure with the same inlet and outlet diameters, small footprint, beautiful appearance, and easy maintenance. At the same time, it is also equipped with a mechanical seal to improve the reliability and service life of operation.

[0003] However, the current hot water circulation pump does not have a special cooling device to cool the water pump. During long-term operation, it is easy to cause many disadvantages such as damage to the water pump or inability to operate.

[0024] The beneficial effects of the present invention are:

[0025] 1. In the present invention, a safe and stable high-temperature resistant hot water circulation pump system is described. The main shaft is driven to rotate by starting the motor. The main shaft drives the circulation pump shaft to rotate through the coupling. The circulation pump shaft drives the circulation impeller to rotate, thereby introducing the circulating hot water from the inlet into the circulation pump casing and exporting it through the outlet to realize the circulation and transportation of hot water. At the same time, the circulation pump shaft drives the vertical shaft to rotate by meshing with the active bevel gear and the driven bevel gear. The vertical shaft drives the cooling pump shaft and the cooling impeller to rotate, thereby generating suction in the water inlet pipe, and the cooling water in the water supply pipe is introduced into the refrigeration box. Subsequently, the cooling water flows through the conduit, the second annular cooling cavity, the water inlet pipe, the cooling pump casing, the water outlet pipe, the first annular cooling cavity, the export hole and is discharged from the drain pipe, thereby taking away the heat in the motor casing and the circulation pump casing to achieve the refrigeration effect. The cooling water passing through the refrigeration box is further refrigerated by starting the refrigerator to improve the cooling effect and avoid overheating.

[0026] 2. In the present invention, the safe and stable high-temperature resistant hot water circulation pump system, when the driving motor and the circulation pump body vibrate during operation, drives the base to vibrate synchronously, thereby achieving vibration buffering through the damper and the shock-absorbing spring, and when the base vibrates up and down, drives the stirring shaft and the connecting plate to vibrate up and down synchronously, and the spiral strips in the fixed cylinder drive the connecting plate to move up and down while rotating repeatedly through the cooperation with the spiral grooves on the connecting plate, and drives the stirring paddle to rotate through the stirring shaft, so as to improve the refrigeration efficiency of the refrigerator for cooling water, and the stirring paddle will be subject to the resistance of the water flow when reciprocating, thereby further buffering the vibration of the base;

[0027] 3. In the present invention, the safe and stable high-temperature hot water circulation pump system drives the rotating frame to rotate through the circulation pump shaft, so that the connecting frame and the counterweight block generate outward centrifugal force. The connecting frame pushes the annular track to move to the right through the cooperation of the triangular plate and the trapezoidal plate, thereby squeezing the compression spring and causing the pressure plate to squeeze the varistor. After the varistor is squeezed, the resistance decreases, thereby increasing the power of the refrigerator. The faster the circulation pump shaft rotates, the greater the power of the refrigerator. Therefore, the cooling speed of the circulation pump body can be adjusted according to the operating speed of the circulation pump body to avoid overheating.

[0028] 4. In the present invention, the safe and stable high-temperature resistant hot water circulation pump system monitors the temperature of the front and rear sides of the motor housing through thermistors, and the thermistors use negative coefficient thermistors, so that the higher the temperature of the thermistor, the lower the resistance, the greater the corresponding electromagnet current, the greater the adsorption force on the iron sheet, and the greater the degree of retraction of the second gate into the second square groove, so that the cooling water flowing from the bottom of the second annular cooling cavity will flow more upward through the side with higher temperature. If the temperature on the front side of the motor housing is higher, the second gate on the front side will be retracted to a greater extent, and the conduction area of ​​the front half of the second annular cooling cavity will be larger, so that more cooling water will flow from the front side of the second annular cold cavity, thereby improving the cooling speed of the front side of the motor housing. Relying on this automatic adjustment of water supply method, the temperature balance of the front and rear sides of the motor housing can be achieved;

[0029] 5. In the present invention, in the safe and stable high-temperature resistant hot water circulating pump system, when cooling water flows through the first annular cooling cavity, heat is transferred to the elastic body through the mounting tube and the sliding cylinder. The elastic body expands due to heat, and the higher the temperature, the greater the expansion degree, and pushes the first gate plate to move to the side away from the mounting tube, so that the side with higher temperature of the first annular cooling cavity has a larger conduction area and a larger cooling water flow rate, thereby improving the cooling effect on the side with higher temperature of the circulating pump casing, so as to ensure the temperature balance of the front and rear sides of the circulating pump casing;

[0030] 6. In the present invention, the safe and stable high-temperature resistant hot water circulation pump system monitors the temperature of the cooling water from the outlet hole through the temperature sensor. The cooling water there has been heated by the motor housing and the circulation pump housing. The current heating conditions of the motor housing and the circulation pump housing can be determined by monitoring the temperature. When the temperature sensor detects that the water temperature is overheated, the drive motor is controlled to stop running, thereby avoiding overheating damage;

[0031] 7. In the present invention, the safe and stable high-temperature resistant hot water circulating pump system can realize automatic cooling of the circulating pump during the operation of the circulating pump system through the cooling pump body and refrigeration mechanism, and can adjust the cooling rate according to the operating speed of the circulating pump through the linkage mechanism, thereby ensuring the cooling effect of the circulating pump, thereby improving its high-temperature resistance and ensuring safe and stable use.

[0068] When the driving motor 2 and the circulating pump body 1 vibrate during operation, the base 11 is driven to vibrate synchronously, so that the vibration is buffered by the damper 302 and the shock-absorbing spring 303, and the base 11 drives the stirring shaft 9 and the connecting plate 903 to vibrate synchronously up and down when vibrating up and down, and the spiral strip 90401 in the fixed cylinder 904 drives the connecting plate 903 to move up and down while rotating repeatedly through the cooperation with the spiral groove 90301 on the connecting plate 903, and drives the stirring paddle 901 to rotate through the stirring shaft 9, so as to improve the cooling efficiency of the refrigerator 1001 for cooling water, and the stirring paddle 901 will be subject to the resistance of the water flow when rotating back and forth, so as to further buffer the vibration of the base 11;

[0069] The rotating frame 603 is driven to rotate by the circulating pump shaft 104, so that the connecting frame 602 and the counterweight block 601 generate outward centrifugal force. The connecting frame 602 pushes the annular track 606 to move rightward through the cooperation of the triangular plate 604 and the trapezoidal plate 605, so as to squeeze the compression spring 609 and make the pressure plate 611 squeeze the varistor 610. After the varistor 610 is squeezed, the resistance decreases, so that the power of the refrigerator 1001 is increased. The faster the rotating speed of the circulating pump shaft 104 is, the greater the power of the refrigerator 1001 is, so that the cooling speed can be adjusted according to the operating speed of the circulating pump body 1 to avoid overheating.

[0070] The temperatures of the front and rear sides of the motor housing 201 are monitored by the thermistor 704, and the thermistor 704 adopts a negative coefficient thermistor, so that the higher the temperature of the thermistor 704, the lower the resistance, the greater the current of the corresponding electromagnet 703, the greater the adsorption force on the iron sheet 701, and the greater the degree of retraction of the second gate plate 7 into the second square groove 20102, so that the cooling water flowing in from the bottom of the second annular cooling cavity 20101 will flow upward through the side with higher temperature. If the temperature on the front side of the motor housing 201 is higher, the second gate plate 7 on the front side will be retracted to a greater extent, and the conduction area of ​​the front half of the second annular cooling cavity 20101 will be larger, so that more cooling water will flow from the front side of the second annular cooling cavity, thereby improving the cooling speed of the front side of the motor housing 201. By relying on this automatic adjustment of water supply, the temperature balance of the front and rear sides of the motor housing 201 can be achieved;

[0071] When the cooling water flows through the first annular cooling cavity 10101, it transfers heat to the elastic body 802 through the mounting cylinder 804 and the sliding cylinder 803. The elastic body 802 expands due to the heat, and the higher the temperature, the greater the expansion degree, and pushes the first gate plate 8 to move to the side away from the mounting cylinder 804, so that the side with a higher temperature of the first annular cooling cavity 10101 has a larger conduction area and a larger cooling water flow rate, thereby improving the cooling effect on the side with a higher temperature of the circulating pump housing 101, so as to ensure the temperature balance of the front and rear sides of the circulating pump housing 101;

[0072] The temperature of the cooling water in the outlet hole 10103 is monitored by the set temperature sensor 19. The cooling water there has been heated by the motor housing 201 and the circulating pump housing 101. The current heating conditions of the motor housing 201 and the circulating pump housing 101 can be determined by monitoring the temperature. When the temperature sensor 19 detects that the water temperature is overheated, the drive motor 2 is controlled to stop running, thereby avoiding overheating damage.
