Specific implementation mode
Embodiment 1
It is illustrated below by way of specific implementation mode and in conjunction with attached drawing to technical scheme of the present invention.
A kind of refrigeration central air-conditioner water cycle cooling system as shown in Figure 1, technical process are summarized as follows：
Single refrigeration mode central air-conditioning core composition is with modular refrigeration unit 5 for core, and modular refrigeration unit 5 includes
There are more compressors 51 in parallel, condenser 52, evaporator 53 and electric cabinet, modular refrigeration unit 5 to be associated with two groups of cycles
System, the work sucking of compressor 51 carry out the refrigerant steam of flash-pot 53, realize the cold of refrigerant in condenser 52 after compression
Lime set, then the throttling of expanded valve enter evaporator 53, realize that refrigeration cycle, condenser 52 are usually tubular heat exchanger knot
Structure, refrigerant within the condenser condensation liquefaction release heat by cooling water circulation by heat take to cooling tower 1 realization outwardly dissipate
Hair, high pressure condensate liquid enter evaporator 53 through filter, expansion valve and realize that low pressure is evaporated, and evaporator 53 is also changed frequently with shell and tube
Hot device structure, liquid phase low-pressure gasifying, which is gas phase, in evaporator can absorb amount of heat, and refrigerated circulating water is made to cool down, cold after cooling
Freeze water enter room fan coil 7 carry out heat exchange so that room temperature is reduced, more Fans coil pipes in more rooms are as shown in Figure 1
Parallel connection assembly is conducive to fan coil chilled-water flow loop distribution and is easy to balanced, and torridity summer refrigeration air-conditioner allows people to feel to relax
It is suitable nice and cool.
The reliable and stable work of cooling water circulating pump A1, A2 are also the element of air-conditioning system normal work, in the design,
Mainly the shafting structure of pump is combined and carries out innovative design, convenient for the quick demolition and maintenance of pump；Coordinate in actual axis and hole
In motion thread assembly, in order to realize big bearing function demand, the component ruler of thread spindle nut member similar with what is matched
Very little all larger, it is often all also very easily convenient to be screwed in assembly, and can realize in use bearing capacity it is automatic not
Disconnected locking, thus it is very reliable, but when that need to dismantle, assembly is often very tight, and dismounting is also very difficult, if can be in this condition
It is lower to realize simple easy removal, it appears particularly important and innovative design main points.
Common typical structure as shown in Figure 2 is taken the shafting of circulating pump：
Patent formula of the present invention is applied to shaft components screw-threaded coupling field, and pump shaft 14 and impeller of pump 11, belt pulley 15 are equal
Using Screw assembly, thread rotary orientation is with work and to be carried as energy auto lock direction, needs to utilize innovative design when detachable maintaining
Copper modeling composite pad 12, clip assembly 16 similar nut member can simply be eliminated to screw shaft shoulder end face by operation readiness
Pressure, at this moment nut is with screw part in unloading vacant state, and dismantling becomes simple and convenient as Screw assembly, for solving
Certainly Screw assembly continuous auto lock situation not easy to remove under load effect is largely effective, especially mammoth pump shaft components
Screw-threaded coupling field, such function are particularly important.In addition, copper modeling composite pad, clip pad can play good Stress decomposition and make
With the bearing capacity of effective enhancing structure.
The structure that copper moulds composite pad 12 is as shown in Figure 3：
Round copper packing progress punch process is made and is shaped to copper packing 21 and fin, then in the compound meltable plastic mattress in copper packing both sides
Circle 22, as shown in figure 3, being easy to heat copper packing.
Impeller of pump 11 is compressed copper modeling Composition spacer 12 by being connect with axle thread similar to nut, and impeller of pump 11 is formed with axis
Screw thread is rigidly connected.Impeller of pump 11 need to dismantle but it is very difficult when, using oxy arc among copper modeling Composition spacer 12
Copper packing 21 carries out oxy arc heat treatment, and since the conductivity of heat of copper is fabulous, and the fusing point of plastics is relatively low, and plastics are heated after heating
Solution, impeller of pump 11 and the compression tensile force of shaft shoulder step completely eliminate, and so that impeller of pump 11 is in complete vacant state especially easy
In dismounting.
The structure chart of clip assembly 16 is as shown in Figure 4：
As shown in figure 5,31 section of clip is wedge shape, it is made of to opening structure, flexible collar pad two semicircular ring clip bodies
33 structure is as shown in fig. 6, clip pad both sides are planar structure, and convenient for coordinating with shaft shoulder plane, clip is passed through using bolt 35
Hole on clip ear 32 is assemblied on clip pad and is integrally formed, and is inserted in the pulley 15 that pump shaft 14 screws in similar nut again,
Rationally all locking again makes the pulley 15 of clip, clip pad and similar nut be constituted with pump shaft 14 and is rigidly connected, full
Sufficient requirement.When the pulley 15 of similar nut need to dismantle but it is very difficult when, bolt 35 is removed with spanner,
It is fast that wedge-shaped and 32 end of clip ear inner surface is equipped with to opening structure, clip body section to be because of two semicircular ring clip bodies
Angle can easily be pried open from the two clip ears 32 connection place of closing up with the flat tool in one end, clip easy removal got off, clip
Pad returns to relaxed state, so that pulley 15 is completely eliminated with the tensile force after the locking of shaft shoulder end face, makes pulley
15 can be in complete vacant state similar to nut is especially susceptible to dismantle.
The specific guiding embodiment of the present invention is above are only, but the design concept of the present invention is not limited thereto,
All changes for carrying out unsubstantiality to the present invention using this design, should all belong to the behavior for invading protection scope of the present invention.
