Description
Technical field
The utility model relates to Compressor Technology field, is specifically related to a kind of horizontal compressor and is provided with the air conditioner of this horizontal compressor.
Background technique
Housing is divided into chamber, left and right by auxiliary bearing by traditional horizontal compressor oil and gas path design, and make exhaust throttle step-down by the circular gap between auxiliary bearing and housing, thus meet the pressure reduction of oil sump in chamber, housing left and right, improve left chamber fuel head, but traditional scheme can cause exhaust, and crushing is large, and oiling compressor amount is large, and motor easily stirs oil, and exhaust can not abundant cooling motor, causes compressor overall power larger.
As Figure 1-3, existing horizontal compressor oil and gas path design and structure thereof, primarily of housing 1, motor 2, outlet pipe 4, 30 main shafts, 33 cylinders, main bearing 31, auxiliary bearing 32, upper oil pipe component 5, composition such as fan 302 grade, its principle is when the compressor is operating, pressurized gas is discharged from the outlet valve main bearing 31, the gas of discharging can cavity through between cylinder 33 and housing 1, housing tail chamber (see route described in the arrow Fig. 1) is discharged to again from the gap (see Fig. 2) between auxiliary bearing 32 and housing 1, discharge from the relief opening in housing tail chamber, gap between described auxiliary bearing 32 and housing 1 is circumferentially whole, gas can produce pressure drop through gap to the left side in Fig. 2 from the right side Fig. 2, this will make the low of the right chamber of pressure ratio in the left chamber of auxiliary bearing 32, and leave trimming bottom auxiliary bearing 32 and between housing 1, as shown in Figure 3, be communicated with for both sides oil sump, because auxiliary bearing 32 both sides oil sump communicates and left cavity pressure is low, left chamber pasta can be made higher than right chamber, expediently oil pipe component 5 oil suction.
Described upper oil pipe component 5 is assemblied on auxiliary bearing, during compressor operating, motor 2 rotates and drives main shaft 30 and the fan 302 be assemblied in above rotor to rotate, because fan 302 rotation can make zone line and main shaft 30 head produce certain negative pressure, therefore the tail end of main shaft 30 and head have certain pressure reduction, because main shaft tail end and upper oil pipe component 5 link together, upper oil pipe component 5 is immersed in oil, the pressure reduction supply that oil is produced by fan 302, thus realizes the fuel feeding to the pump housing.
This kind of structure implements more deficiency:
1. as shown in Figure 1; tradition horizontal compressor oil and gas path is due to the fuel head in order to ensure housing tail chamber; so outlet pipe 4 is arranged on housing tail chamber; pressurized gas is discharged to housing tail chamber by the gap between auxiliary bearing 32 and housing 1 after main bearing 31 is discharged; this will cause the gas fluidity of motor cavity poor; be unfavorable for the heat taking away motor, cause motor temperature high, power consumption height even electromotor high-temperature protection is shut down.
2. traditional horizontal compressor is vented the gap that have passed through between auxiliary bearing 32 and housing 1, can produce extra pressure drop, and exhaust pressure loss is large, and this will cause compressor actual operating mode severe, causes power consumption higher.
3. traditional scheme is in order to ensure that the oil sump in auxiliary bearing about 32 chamber is communicated with, auxiliary bearing trimming is left bottom auxiliary bearing 32 and between housing 1, when compressor operating operating mode is lighter, air displacement is larger, this is just likely because the less meeting of the passage gaps between auxiliary bearing 32 and housing 1 makes a part of gas be discharged to left chamber from trimming bottom auxiliary bearing 32, a large amount of bubble is caused in the left chamber of auxiliary bearing 32, because left chamber pasta is higher, compressor can be made to tell oily rate and obviously to increase.
4. traditional scheme is in order to ensure the fuel head in the left chamber of auxiliary bearing, need the oil filling amount ensureing that compressor is enough, but this can cause the rotor of motor cavity to be immersed in oil, and motor can be caused to stir oily phenomenon, and compressor power consumption is increased.
