Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and in particular to an ultra-high temperature water source heat pump. Background Technology

[0002] With the introduction of dual-carbon goals and the continuous advancement of clean energy power generation technologies, heat pumps, as devices capable of recovering medium- and low-temperature waste heat to produce medium- and high-temperature media, will gradually replace various boilers, electric heaters, and other heating equipment and be widely used. When the heat source of a heat pump is water, it is generally called a water source heat pump. However, when existing water source heat pumps operate under conditions of extremely high outlet water temperatures, the refrigerant exhaust temperature and condensation temperature inside the heat pump are extremely high. This also results in high lubricating oil temperatures, preventing it from performing its proper cooling, lubrication, sealing, cleaning, and noise reduction functions. This leads to accelerated compressor wear, unstable operation, and shortened lifespan. Acidic substances produced by the lubricating oil corrode the compressor, and the high temperature of the lubricating oil easily produces decomposition products that contaminate the refrigerant, resulting in reduced cooling efficiency. Components such as the expansion valve inside the heat pump unit cannot withstand the high temperatures, leading to unstable operation or even failure. All of these factors make it difficult for the entire water source heat pump unit to operate stably. Utility Model Content

[0003] The purpose of this invention is to provide an ultra-high temperature water source heat pump to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An ultra-high temperature water source heat pump includes a water pump, a pipeline, a heat exchanger, and a cooling fan. The outlet of the water pump is connected to the inlet of the pipeline. The heat exchanger is located in the middle section of the pipeline. The cooling fan is fixedly mounted on the heat exchanger by a bracket. The water pump includes a fixed plate, a housing, a motor, a rotating shaft, and turbine blades. The housing and the motor are fixedly mounted on the top of the fixed plate, with the motor located on the right side of the housing. A through hole is formed at the center of the right side of the housing, and a sealed bearing is fixedly installed in the through hole. The rotating shaft passes through the sealed bearing, and the right end of the rotating shaft is connected to the output shaft of the motor via a coupling. An insulation sleeve is fitted on the left end of the rotating shaft, and the turbine blades are fitted on the insulation sleeve and located inside the housing. An inlet is provided on the left side of the housing, and an outlet is provided on the top right side of the housing. The outlet is connected to the inlet of the pipeline via a pipe.

[0006] By adopting the above technical solution, since an insulating sleeve is fitted on one end of the rotating shaft inside the housing, and the turbine is fitted on the insulating sleeve, the insulating sleeve can isolate the high-temperature liquid inside the water pump housing from direct contact with the rotating shaft, thus preventing heat from being conducted to the motor through the rotating shaft.

[0007] In a further embodiment, the coupling is provided with a plurality of ventilation holes evenly spaced, and the shaft is provided with a plurality of weight-reduction holes evenly spaced on the right end of the outer side of the housing.

[0008] By adopting the above technical solution, the coupling needs to rotate during operation. The setting of ventilation holes can further increase the difficulty of heat transfer to the motor through the rotating shaft, thus ensuring the stability of the motor's operating environment temperature.

[0009] In a further embodiment, the working surface of the turbine blade is bonded with a conformal corrosion layer.

[0010] By adopting the above technical solution, since the working environment of turbine blades is in a long-term high-temperature liquid, where a large number of bubbles exist, in order to extend the working life of turbine blades and avoid excessive cavitation, a conformal corrosion layer is set on the working surface of the turbine blades. When it is consumed to a certain extent, or after the turbine blades have worked for a certain period of time, it is replaced to better protect the turbine blades.

[0011] In a further embodiment, a covering layer is provided on the outer side of the outer wall of the outer shell. The covering layer consists of a flexible felt layer, a sponge support layer, a shape retention layer and a plastic sealing layer from the inside to the outside. The flexible felt layer, the sponge support layer, the shape retention layer and the plastic sealing layer are bonded and fixed to each other.

[0012] In a further embodiment, the inner wall of the housing is provided with a graphite bushing.

[0013] In a further embodiment, a heating device is fitted at the outlet end of the pipeline.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. An insulating sleeve is fitted on one end of the rotating shaft inside the housing. The turbine is fitted on the insulating sleeve. The insulating sleeve can isolate the high-temperature liquid inside the water pump housing from direct contact with the rotating shaft, thus preventing heat from being conducted to the motor through the rotating shaft.

[0022] Example 1:

[0023] like Figures 1-3As shown, an ultra-high temperature water source heat pump includes a water pump 1, a pipeline 2, a heat exchanger 3, and a cooling fan 4. The outlet of the water pump 1 is connected to the inlet of the pipeline 2. The heat exchanger 3 is located in the middle section of the pipeline 2. The cooling fan 4 is fixedly mounted on the heat exchanger 3 by a bracket. The water pump 1 includes a fixing plate 11, a housing 12, a motor 13, a rotating shaft 14, and turbine blades 15. The housing 12 and the motor 13 are fixedly mounted on the top of the fixing plate 11, and the motor 13 is located on the right side of the housing 12. A through hole is opened at the center of the right side of the housing 12. A sealed bearing is fixedly installed in the through hole. The rotating shaft 14 passes through the sealed bearing. The right end of the rotating shaft 14 is connected to the output shaft of the motor 13 through a coupling. A heat-insulating sleeve 5 is fitted onto the left end of the rotating shaft 14. The turbine blade 15 is fitted onto the heat-insulating sleeve 5 and is located inside the outer casing 12. A water inlet is provided on the left side of the outer casing 12, and a water outlet is provided on the top right side of the outer casing 12. The water outlet is connected to the water inlet of the pipeline through a pipe. Multiple ventilation holes are evenly distributed on the coupling. Multiple weight-reducing holes are evenly distributed on the right end of the rotating shaft 14 located outside the outer casing 12. The coupling needs to rotate during operation. The ventilation holes further increase the difficulty of heat transfer to the motor through the rotating shaft, ensuring a stable operating temperature for the motor. A conformal corrosion layer 6 is bonded and fixed to the working surface of the turbine blade 15. The operating environment is a long-term high-temperature liquid environment containing a large number of bubbles. Therefore, to extend the service life of the turbine blades and prevent excessive cavitation, a conformal corrosion layer is formed on the working surface of the turbine blades. This layer is replaced when it is worn down to a certain extent or after a certain number of operating cycles to better protect the turbine blades. The outer wall of the outer shell 12 is provided with a covering layer 7, which consists of, from the inside out, a flexible felt layer 71, a sponge support layer 72, a shape-retaining layer 73, and a plastic sealing layer 74. These layers are bonded together. The flexible felt layer 71 is composed of dense, long fibers and is mainly used for… The outer casing 12 is fitted to the outer wall to prevent external wind from entering between the covering layer and the outer wall through any gaps. The sponge support layer 72 provides structural support and reduces temperature transfer through the sponge's natural porous structure. The shape-maintaining layer 73, typically made of wire mesh, maintains the final shape of the entire covering layer. The plastic sealing layer 74 is usually wrapped with thick tape on the outermost layer to reduce the contact area between the outer wall and the wind, thus providing insulation. The inner wall of the outer casing 12 is fitted with a graphite bushing. During use, water enters the casing and is rotated by the turbine blades. The air bubbles contained in the water slowly erode the inner wall of the casing. The graphite bushing protects the inner wall of the casing. A heating device is fitted at the outlet of the pipe 2.The outlet of the pipeline is connected to the equipment. Therefore, to prevent the high-temperature liquid from entering the equipment from failing to meet the required temperature, a heating device is installed at the outlet. This ensures the liquid reaches the correct temperature before entering the equipment and also reduces heat loss.

[0024] Specific implementation process: An insulating sleeve is fitted on one end of the rotating shaft inside the housing, and the turbine is fitted on the insulating sleeve. The insulating sleeve can isolate the high-temperature liquid inside the water pump housing from direct contact with the rotating shaft, thus preventing heat from being conducted to the motor through the rotating shaft.
