Description
Technical field
The utility model is related to field of air conditioning more particularly to a kind of magnetic suspension air-conditionings.
Background technology
The core of magnetic suspension air-conditioning is magnetic suspension compressor, and the core of magnetic suspension compressor is magnetic suspension bearing,
Magnetic suspension bearing be it is a kind of using magneticaction by rotor suspension in the air, make the dress for not having Mechanical Contact between rotor and stator
Structure is set, compared with traditional bearing, Mechanical Contact is not present in magnetic suspension bearing, and rotor can run to very high rotating speed, have
Mechanical wear is small, low energy consumption, noise is small, long lifespan, without lubricating the advantages that, particularly suitable for particular surroundings such as high speed, vacuum
In.
In order to ensure the safety and reliability of magnetic suspension bearing, generally requires and assemble a set of protection axis in two ends of rotor
It holds, for bearing radial load.But protection bearing is mechanical bearing, mechanical bearing honours wanting for working environment with magnetic suspension shaft
It asks and is different, magnetic suspension bearing is insensitive to environment temperature without lubricating, and mechanical bearing needs to use lubricating oil or lubrication
Fat, and when operating temperature is higher lubrication failure, carbonization, the even stuck failure of rolling element can occur.
Magnetic suspension bearing usually in unlubricated, low cooling, therefore protect bearing with regard to must it is this relative to it for compared with
To work under rugged environment, the general grease lubrication rolling bearing for selecting with closure, but air-conditioning easy tos produce height at runtime
Warm environment, this protection bearing are still easy to fail because of high temperature, as lubricating grease viscosity declines, loss, even carburizing sintering
Deng to reduce the reliability of magnetic suspension air-conditioning.
Therefore, the prior art is defective, needs to improve.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, a kind of magnetic suspension air-conditioning are provided, in operation of air conditioner
Air-conditioning heat dissipation is given in time, improves the reliability of magnetic suspension air-conditioning.
The technical solution of the utility model is as follows：A kind of magnetic suspension air-conditioning, including：Compressor, condenser, evaporator and
Throttle valve.The compressor includes magnetic suspension bearing, and the magnetic suspension bearing includes：Pedestal, set on determining for the base interior
Son is set to the first protection bearing in the pedestal and positioned at the stator side, is set on the pedestal and close to described the
First cooling chamber of one protection bearing is set to the second protection bearing in the pedestal and positioned at the stator other side, is set to
The second cooling chamber for protecting bearing on the pedestal and close to described second passes through described first to protect bearing, the second protection axis
The protective case for holding the rotor with stator and being sleeved on the rotor, when magnetic suspension air-conditioning powers off or other exceptions occurs,
The orbit of shaft center of rotor can become larger, and protective case can protect rotor not to be in direct contact with stator.
Be equipped with the first water outlet and the first inlet channel above first cooling chamber, first water outlet and first into
Water channel is connected to the first cooling chamber, the second water outlet and the second inlet channel is equipped with above second cooling chamber, described second goes out
Water channel and the second inlet channel are connected to the second cooling chamber.
First water outlet and the first inlet channel are fixed by welding in the first cooling chamber, second water outlet with
Second inlet channel is fixed by welding in the second cooling chamber.
The first protection bearing and the second protection bearing are deep groove ball bearing.
Using the above scheme, the utility model provides a kind of magnetic suspension air-conditioning, used in bearing be magnetic suspension bearing, no
Only have the advantages that small starting current, operation low noise, energy delivery efficiency are high, and by giving two guarantors in magnetic suspension bearing
Shield bearing is separately equipped with a cooling chamber, can effectively reduce the temperature of two protection bearings, and then reduce its failure rate, improves magnetic
The reliability of suspension air-conditioning.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, the utility model provides a kind of magnetic suspension air-conditioning, including：Compressor, condenser, evaporator and
Throttle valve.The compressor includes magnetic suspension bearing, and the magnetic suspension bearing includes：Pedestal 1 is set to inside the pedestal 1
Stator 2 is set to the first protection bearing 2 in the pedestal 1 and positioned at 2 side of the stator, is set on the pedestal 1 and close
First cooling chamber 4 of the first protection bearing 3 is set to the second protection in the pedestal 1 and positioned at 2 other side of the stator
Bearing 5, the second cooling chamber 6 for being set on the pedestal 1 and protecting bearing 5 close to described second pass through described first to protect axis
The protective case 8 for holding the rotor 7 of the 3, second protection bearing 5 and stator 2 and being sleeved on the rotor 7.When magnetic suspension air-conditioning powers off
Or when occurring other abnormal, the orbit of shaft center of rotor 7 can become larger, and protective case 8 can protect rotor 7 not occur with stator 2
It is in direct contact.It is deep groove ball bearing that the first protection bearing 3 and second, which protects bearing 5,.
The top of first cooling chamber 4 is equipped with the first water outlet 41 and the first inlet channel 42, first water outlet 41 and
First inlet channel 42 is fixed by welding in the first cooling chamber 4, first water outlet, 41 and first inlet channel 42 and
