Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to a high-efficiency high-temperature resistant centrifugal pump structure. Background Technology

[0002] A centrifugal pump is a machine that uses the centrifugal force generated by the rotation of a rotating impeller to transport fluids. Currently, centrifugal pumps are designed and installed with the pump's location and the direction of the inlet and outlet on the pump casing planned according to the layout of the connecting pipes. However, during the use of a centrifugal pump, the position of the connecting pipes is often changed, resulting in a mismatch between the pump's outlet position and the connecting pipe position, affecting the connection between the connecting pipes and the pump's outlet.

[0003] A centrifugal pump is disclosed in the prior art patent application with publication number CN 211852277 U. The centrifugal pump provided by this utility model has a support ring on the support, and a clamping ring and a pump housing are used to clamp the support ring. After the clamping ring is released from the pump housing, the pump housing and the clamping ring can be rotated on the support ring at the same time, so that the position of the liquid outlet corresponds to the connecting pipe. After the adjustment is completed, the pump housing and the clamping ring are fixed, and the clamping ring is clamped to fix the position of the pump housing. In this way, after the connection position of the connecting pipe corresponding to the liquid outlet is changed, it is not necessary to change the installation position of the centrifugal pump support. Only the rotation angle of the pump housing and the clamping ring on the support ring needs to be adjusted to adjust the position of the liquid outlet, which facilitates the connection between the centrifugal pump and the connecting pipe.

[0004] However, in the existing technology, the device has a complex structure, high manufacturing cost, and high maintenance cost, resulting in low practicality. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency, high-temperature resistant centrifugal pump structure, which aims to solve the problems of the existing technology, such as the complex structure, high manufacturing cost, and high maintenance cost, which leads to the low practicality of the device.

[0006] To achieve the above objectives, this utility model provides a high-efficiency high-temperature resistant centrifugal pump structure, including a mounting frame and a conveying mechanism. The conveying mechanism includes a drive motor, a drive shaft, multiple rotating impellers, a housing, an inlet pipe, an outlet pipe, and a support assembly. The support assembly includes a mounting frame and a bearing. The housing is fixedly connected to one end of the drive motor. The drive shaft is fixedly connected to the drive motor and extends into the housing. The multiple rotating impellers are fixedly connected to the drive shaft and arranged in an array, with the multiple rotating impellers located inside the housing. The inlet pipe is fixedly connected to the housing and located at the end of the housing away from the drive motor. The outlet pipe is fixedly connected to the housing and located above the housing. The support assembly is disposed inside the housing. The mounting frame is fixedly connected to the housing and located inside the housing. The outer side wall of the bearing is rotatably connected to the mounting frame, and the inner side wall of the bearing is rotatably connected to the drive shaft.

[0007] The conveying mechanism further includes a filter assembly, which is disposed on the water inlet pipe and located at the end of the water inlet pipe away from the housing.

[0008] The filter assembly includes a threaded cylinder and a filter plate. The inlet pipe has an external thread, and the threaded cylinder is threadedly connected to the inlet pipe through the external thread. The filter plate is fixedly connected to one end of the threaded cylinder.

[0009] The conveying mechanism further includes auger blades, which are fixedly connected to the outer wall of the drive shaft and located inside the water inlet pipe.

[0010] The conveying mechanism further includes a sound insulation layer, which is fixedly connected to the housing and located on the outer side wall of the housing.

[0011] This utility model discloses a high-efficiency, high-temperature resistant centrifugal pump structure. When using this utility model to transport water, the water source is connected to the inlet pipe, allowing the water to enter the housing. The drive motor is started, and the drive motor drives the drive shaft and multiple rotating impellers to rotate at high speed. The high-speed rotation of the multiple rotating impellers generates centrifugal force, and the water flow is thrown outwards from the rotating impellers under the action of centrifugal force. At the same time, a low-pressure zone is formed in the middle of the rotating impellers, and the water flow outside the housing is drawn into the low-pressure zone in the middle of the rotating impellers. The thrown-out water flow is discharged from the housing through the outlet pipe, thereby achieving the effect of transporting water. The mounting bracket and the bearing provide auxiliary support for the drive shaft, ensuring that the drive shaft will not be misaligned when rotating at high speed, increasing the structural stability of the device. The device has a simple structure, low manufacturing cost, and low subsequent maintenance cost, thus improving the practicality of the device. Attached Figure Description

[0019] This utility model provides a high-efficiency high-temperature resistant centrifugal pump structure, including a mounting frame 111 and a conveying mechanism. The conveying mechanism includes a drive motor 101, a drive shaft 102, auger blades 110, a sound insulation layer 105, a filter assembly, multiple rotating impellers 103, a housing 104, an inlet pipe 106, an outlet pipe 107, and a support assembly. The support assembly includes the mounting frame 111 and a bearing 112. The filter assembly includes a threaded cylinder 108 and a filter plate 109. The inlet pipe 106 has an external thread 113. The aforementioned solution solves the problem that in the prior art, the device has a complex structure, high manufacturing cost, and high maintenance costs, resulting in low practicality of the device.

[0020] In this embodiment, the housing 104 is fixedly connected to one end of the drive motor 101, the drive shaft 102 is fixedly connected to the drive motor 101 and extends into the housing 104, a plurality of rotating impellers 103 are fixedly connected to the drive shaft 102 and arranged in an array, and the plurality of rotating impellers 103 are located inside the housing 104, the water inlet pipe 106 is fixedly connected to the housing 104 and is located at the end of the housing 104 away from the drive motor 101, the water outlet pipe 107 is fixedly connected to the housing 104 and is located above the housing 104, the support assembly is disposed inside the housing 104, the mounting bracket 111 is fixedly connected to the housing 104 and is located inside the housing 104, the outer side wall of the bearing 112 is rotatably connected to the mounting bracket 111, and the inner side wall of the bearing 112 is rotatably connected to the drive shaft 102. When using this utility model to transport water, the water source is connected to the... The water inlet pipe 106 is connected to allow water to enter the housing 104. The drive motor 101 is then started, driving the drive shaft 102 and multiple rotating impellers 103 to rotate at high speed. The high-speed rotation of the multiple rotating impellers 103 generates centrifugal force, and the water flow is thrown outwards from the rotating impellers 103 under the action of centrifugal force. At the same time, a low-pressure zone is formed in the middle of the rotating impellers 103, and the water flow outside the housing 104 is drawn into the low-pressure zone in the middle of the rotating impellers 103. The thrown-out water flow is discharged from the housing 104 through the water outlet pipe 107, thereby achieving the effect of water supply. The mounting bracket 111 and the bearing 112 provide auxiliary support for the drive shaft 102, ensuring that the drive shaft 102 will not be misaligned when rotating at high speed, thus increasing the structural stability of the device. The device has a simple structure, low manufacturing cost, and low subsequent maintenance costs, thereby improving the practicality of the device. The connection between the drive motor 101 and the drive shaft 102 is coated with grease. The grease can absorb the heat emitted from the output end of the drive motor 101, giving the device the characteristic of high temperature resistance.

[0021] Furthermore, the filter assembly is disposed on the water inlet pipe 106 and located at the end of the water inlet pipe 106 away from the housing 104.

[0022] Furthermore, the threaded cylinder 108 is threadedly connected to the water inlet pipe 106 via the external thread 113, and the filter plate 109 is fixedly connected to one end of the threaded cylinder 108.

[0023] In this embodiment, the water flows through the filter plate 109 before entering the housing 104 through the inlet pipe 106. The filter plate 109 filters impurities in the water, preventing small stones or other debris from entering the housing 104 and causing device malfunction, thereby ensuring the safety of the multiple rotating impellers 103 and reducing the maintenance cost of the device. The filter plate 109 can be disassembled through the threaded cylinder 108 and the external thread 113 to facilitate cleaning by the operator.

[0024] Furthermore, the auger blade 110 is fixedly connected to the outer wall of the drive shaft 102 and is located inside the water inlet pipe 106.

[0025] In this embodiment, when the drive shaft 102 rotates, it simultaneously drives the auger blade 110 to rotate. As the auger blade 110 rotates, the water flow will follow the spiral structure of the auger blade 110 and enter the housing 104 more quickly, thus demonstrating the high efficiency of the device.

[0026] Furthermore, the sound insulation layer 105 is fixedly connected to the housing 104 and is located on the outer side wall of the housing 104.

[0027] In this embodiment, the sound insulation layer 105 can reduce the noise generated when the device is working, thereby improving the practicality of the device.

[0028] When using this utility model to transport water, the water source is connected to the inlet pipe 106, allowing the water to enter the housing 104. The drive motor 101 is then started, driving the drive shaft 102 and multiple rotating impellers 103 to rotate at high speed. The high-speed rotation of the multiple rotating impellers 103 generates centrifugal force, causing the water to be thrown outwards around the rotating impellers 103 under the action of centrifugal force. At the same time, a low-pressure zone is formed in the middle of the rotating impellers 103, and the water outside the housing 104 is drawn into the low-pressure zone in the middle of the rotating impellers 103. The thrown-out water is discharged from the housing 104 through the outlet pipe 107, thereby achieving the effect of transporting water. The mounting bracket 111 and the bearing 112 provide auxiliary support for the drive shaft 102, ensuring that the drive shaft 102 will not be misaligned when rotating at high speed, thus increasing the structural stability of the device. The device has a simple structure, low manufacturing cost, and low subsequent maintenance costs, thereby improving the practicality of the device.
