Description

Technical Field

[0001] The present invention relates to the technical field of rotor impellers, in particular to a wear-resistant rotor impeller for a heat pump. Background Art

[0002] A heat pump air conditioning unit is a device that uses heat pump technology to achieve cooling and heating functions. During the operation of a large heat pump air conditioning unit, the quality of its water source is particularly important. If the water source contains sand, moss or other impurities, although the filter can filter out some of the oversized impurities, some impurities will still enter the water pump under the suction action of the water pump. When dealing with poor water quality, the water pump usually uses a large-pitch impeller. Although the head is reduced, it is less likely to clog and has less wear than a small impeller. In actual use, different impellers need to be replaced manually. In order to ensure water supply efficiency, the current heat pump uses a wear-resistant rotor impeller. Usually, the blade spacing is small, which is easy to clog when inhaling impurities. It is not convenient to automatically control the anti-blocking protection without stopping the machine, and to ensure water supply efficiency when the water quality meets the standard. The manual replacement of the impeller is not efficient enough, nor is it timely. It is also not convenient to maintain an anti-wear balance seal.

[0021] Among them, the impeller part 1 also includes: a rotation limiting shell 102, fixed blades 1021, a front baffle 1022 and an electromagnet 103. The rotation limiting shell 102 is fixedly mounted on the rear baffle 1011, and the middle part of the rotation limiting shell 102 passes through the impeller main shaft 101; a circle of fixed blades 1021 is fixedly mounted on the rotation limiting shell 102; a circle of through grooves is provided on the rotation limiting shell 102, and the circle of through grooves on the rotation limiting shell 102 are respectively located between a circle of fixed blades 1021; a front baffle 1022 is fixedly mounted on a circle of fixed blades 1021; a water inlet through hole communicating with the fixed blades 1021 is provided in the middle of the front baffle 1022; the fixed blades 1021 are fixedly mounted on the inner side of the rear baffle 1011; a circle of electromagnets 103 are fixedly mounted inside the rotation limiting shell 102, and a circle of electromagnets 103 are equidistantly distributed, and a The circle electromagnets 103 are respectively misaligned with the roots of a circle of fixed blades 1021; the rotary distance adjusting member 2 includes: a rotary ring 201 and movable blades 202, the rotary ring 201 is rotatably mounted inside the rotary limit shell 102; a circle of movable blades 202 is fixedly mounted on the rotary ring 201, and a circle of movable blades 202 respectively pass through a circle of through grooves on the rotary limit shell 102; a circle of movable blades 202 are respectively used to fit the side surfaces of a circle of fixed blades 1021; the rear side of a circle of movable blades 202 is attached to the rear baffle 1011, and the front side of a circle of movable blades 202 is attached to the front baffle 1022; the rotary distance adjusting member 2 also includes: a magnetic block 203, a circle of magnetic blocks 203 is fixedly mounted on the inner side of the rotary ring 201; a circle of magnetic blocks 203 are respectively located inside the rotary limit shell 102; a circle of electromagnets 103 are magnetically attached to the magnetic blocks 203;When a circle of electromagnets 103 are magnetically attached to the magnetic block 203, the spacing between a circle of movable blades 202 and a circle of fixed blades 1021 is the same. This structure adopts a rotary pitch-adjusting member 2 in conjunction with the impeller portion 1 to achieve blade pitch adjustment, which can better adapt to different blade spacing requirements. At the same time, this structure can achieve automatic control and adjustment without stopping the machine.

It can achieve rapid adjustment without stopping the machine, and can also ensure a high-lift water discharge effect when the water quality is free of impurities. , eliminating the need for tedious manual adjustments and making it more reasonable. At the impeller outlet, a larger blade pitch can improve the impeller's anti-cavitation performance because the larger pitch facilitates the diffusion and discharge of bubbles.

A smaller blade pitch can increase the impeller's ability to propel the liquid, thereby increasing the flow rate and lift of the water pump. This structure can automatically adapt and adjust to achieve a balance between flow rate, lift, and anti-clogging and wear resistance. When the fixed blades 1021 rotate, if the impurity content exceeds the standard, the electromagnet 103 is de-energized and no longer magnetically attracts the magnetic block 203. At this point, the movable blades 202 lose their limit, and the impeller main shaft 101 continues to rotate. Under centrifugal force, the movable blades 202 can retreat closer to the fixed blades 1021, achieving the purpose of increasing the pitch.

[0022] Among them, the impurity detection part 3 includes: a detection sliding column 301 and a detection frame 302, the detection sliding column 301 is slidably installed on the impeller main shaft 101; the detection frame 302 is fixedly installed at the front end of the detection sliding column 301; the detection frame 302 is a mesh structure; the front side of the detection sliding column 301 is a conical structure; the detection frame 302 is located in the middle of the front baffle 1022; the detection frame 302 is used to detect impurities; the detection frame 302 is an umbrella-shaped structure; the front baffle 1022 is a chamfered structure near the outer ring of the detection frame 302; the impurity detection part 3 also includes: a retraction spring 303 and a control switch 304, the retraction spring 303 is sleeved on the front end of the impeller main shaft 101; the end of the retraction spring 303 is connected to the tail of the detection sliding column 301; the tail of the detection sliding column 301 is fixed A control switch 304 is fixedly installed, and a gap is provided between the control switch 304 and the inner side of the front end of the impeller main shaft 101; the power control component 4 includes: a power cover 401, a power spring 402 and a power ring 403, and the power cover 401 is sleeved on the impeller main shaft 101; a circle of through holes is provided on the power cover 401, and the circle of through holes on the power cover 401 is used to connect the motor end cover through bolts; two circles of power springs 402 are fixedly installed on the inner side of the power cover 401; two power rings 403 are fixedly installed on the impeller main shaft 101, and the two power rings 403 are respectively aligned with the power springs 402, and the two circles of power springs 402 elastically fit the two power rings 403 respectively; the electromagnet 103, the control switch 304, the power spring 402 and the power ring 403 are electrically Connection; The impurity detection part 3 is used to automatically detect the impurities in the inhaled water. When it contains more impurities such as sand and stones, it can automatically control to increase the impeller blade spacing, which does not affect the normal water flow and ensures the water supply efficiency. At the same time, this structure can use the resistance of impurities or the impact force when the impurities are inhaled to automatically detect, and avoid under the action of suction, although the detection frame 302 isolates some larger impurities, but smaller impurities such as moss are easy to clog the fixed blades 1021 and the movable blades 202 after passing through the detection frame 302. This structure can realize automatic detection work, and use the resistance of sucking in soil, sand or garbage to automatically control to increase the blade spacing. No manual adjustment is required, and protection work can be carried out more timely. When sucking to the mud bottom or moss, the size is not The impurities will be mixed and sucked into the detection frame 302. At this time, the detection frame 302 is hit by the impurities, and small particles of impurities or moss pass through the detection frame 302. Under the action of water pressure, the detection frame 302 has reduced surface permeability after being attached with impurities, and the resistance increases, so it will move backward. At the same time, the impurities on the detection frame 302 with an umbrella-shaped inclined surface structure will gradually move outward, pass between the detection frame 302 and the inner chamfer of the front baffle 1022, and be sucked away. At the same time, when the impurities are sucked in, they will hit the detection frame 302 and move backward, driving the detection sliding column 301 and the control switch 304 to move and squeeze the impeller main shaft 101. At this time, the control switch 304 can control the electromagnet 103 to quickly cut off the power; the power control component 4 can maintain real-time power supply and will not affect the normal rotation of the impeller main shaft 101.

[0023] Example 2, based on Example 1, the defoaming auxiliary component 5 includes: a rotating connecting ring 501, a button battery 5011 and an expansion airbag 502, two rotating connecting rings 501 are provided, and the structures on the two rotating connecting rings 501 are the same; the two rotating connecting rings 501 are rotatably mounted on the outside of the front baffle 1022 and the rear baffle 1011 respectively; a button battery 5011 is fixedly mounted on the side of the rotating connecting ring 501, and the button battery 5011 is sealed; an expansion airbag 502 is fixedly mounted on the rotating connecting ring 501, and there is air pressure in the expansion airbag 502; the defoaming auxiliary component 5 also includes: a fixed ring 503 and an eccentric spring piece 504, the fixed ring 503 is fixedly installed on the inner ring of the expansion airbag 502; a circle of eccentric spring pieces 504 is fixedly installed inside the expansion airbag 502, and a gap is set between the ends of the circle of eccentric spring pieces 504 and the fixed ring 503; the fixed ring 503 is used to fit the eccentric spring piece 504; the defoaming auxiliary component 5 also includes: a waterproof buzzer 505, a row of waterproof buzzers 505 is fixedly installed on the rotary connecting ring 501, and the row of waterproof buzzers 505, the fixed ring 503, the eccentric spring piece 504 and the button battery 5011 are connected in series, adopting The defoaming auxiliary component 5 can utilize air pressure to fit on the inner wall of the impeller shell, and can isolate the two sides of the fixed blade 1021, so as to avoid that the gap between the outer side of the traditional front baffle 1022 and the inner wall of the impeller shell gradually increases with the increase of the service cycle. In the subsequent rotation process, a large number of bubbles will be generated between the inner wall of the impeller shell and the outer sides of the front baffle 1022 and the rear baffle 1011, further increasing the problem of cavitation. This structure can ensure sealing and fitting protection, and has a longer service life. At the same time, this structure can automatically perform eccentric balance test, and can provide prompts in time. It is convenient for staff to carry out timely maintenance. Impeller eccentricity will cause the water pump to vibrate at a long distance during operation. The vibration will not only damage the bearings, rotor and other components of the water pump, but may also cause the motor to stray, resulting in violent and uniform vibration of the unit, and at the same time, it will also aggravate cavitation wear. The front baffle 1022 and the rear baffle 1011 rotate on the rotating connecting ring 501 on the inner side respectively. If the impeller main shaft 101 shakes and is eccentric, it will also drive the rotating connecting ring 501 to shake together, driving the fixed ring 503 to touch the eccentric spring piece 504. At this time, the waterproof buzzer 505 will sound an alarm.

[0024] The working principle of this embodiment is as follows: first, the expansion airbag 502 is placed in the impeller shell. After the impeller shell is closed, the expansion airbag 502 can be fitted and sealed inside the shell. The impeller main shaft 101 is connected to the motor main shaft. A circle of through holes on the power cover 401 is connected to the motor end cover through bolts. At this time, when the impeller main shaft 101 is driven to rotate, the power ring 403 can be driven to rotate together. At this time, the power spring 402 elastically fits the power ring 403 to connect to the power. The power spring 402 can be connected to an external power source. When the front baffle 1022 and the rear baffle 1011 are driven to rotate, the expansion airbag 502 can remain fitted inside the impeller shell. When the mud or moss is sucked to the bottom When the impurities are sucked into the detection rack 302, the detection rack 302 is hit by the impurities. Small particles of impurities or moss pass through the detection rack 302. Under the action of water pressure, the detection rack 302 has reduced surface permeability after being attached with impurities, and the resistance increases, so it will move backward. At the same time, the impurities on the detection rack 302 with an umbrella-shaped inclined surface structure will gradually move outward, pass between the detection rack 302 and the inner chamfer of the front baffle 1022, and be sucked away. At the same time, when the impurities are sucked in, they will hit the detection rack 302 and move backward, driving the detection sliding column 301 and the control switch 304 to move and squeeze the impeller main shaft 101. At this time, the control switch 304 can control the electromagnet 103 to quickly When the power is turned off, the electromagnet 103 is powered off and no longer magnetically attracts the magnetic block 203. At this time, the movable blade 202 loses its limit, and the impeller main shaft 101 still keeps rotating. Under the centrifugal force, the movable blade 202 can retreat and approach the fixed blade 1021. A small amount of impurities between the fixed blade 1021 and the movable blade 202 to be approached will be thrown out from the outlet of the movable blade 202 as they rotate under the action of centrifugal force, thereby achieving the purpose of increasing the spacing and avoiding the subsequent continuous inhalation of impurities to continuously damage the blades. At the same time, larger impurities such as stones can also pass between the movable blade 202 and the fixed blade 1021 after the limit is released, because the increased spacing will increase the To improve the passability of impurities, if the subsequent staff removes impurities on the surface of the detection frame 302 or the impurities are naturally sucked through the detection frame 302, the passability of the detection frame 302 will be restored, and the control switch 304 will be reset under the pressure of the retraction spring 303, and the electromagnet 103 will be magnetically attracted to the magnetic block 203 to control the reset of the movable blade 202 and keep it at the interval between the fixed blade 1021; if the impeller main shaft 101 shakes and is eccentric, it will also drive the rotating connecting ring 501 to shake together, and the rotating connecting ring 501 will drive the fixed ring 503 to touch the eccentric spring piece 504, and the waterproof buzzer 505 will be energized to realize the buzzer alarm prompt.
