Hot hole, and multiple filter hole are densely covered on the bucket wall of filter vat and bucket bottom.
Support portion inner cavity, venthole and gas port composition one make the exhaust passage that housing cavity is in communication with the outside, to increase
The approach of enclosure interior and extraneous ventilation is stablized to effectively accelerate the radiating rate of enclosure interior to improve compressor operating
Property.
By setting heat release hole in being arranged obliquely, the probability that the impurity such as dust enter in heat release hole is effectively reduced,
Secondly, filter vat is arranged in blowhole, the impurity such as dust can be further prevented to enter in support portion, to effectively prevent
The exhaust passage stated is blocked, and stablizes the purpose for improving radiating rate and realizes.
In the shell of above-mentioned helical-lobe compressor, the ring coaxial with support portion is offered on the bottom wall of above-mentioned support portion
Connected in star is fixed with ring-shaped rubber pad in above-mentioned annular groove, and annular groove is stretched out in the lower end of ring-shaped rubber pad.Actually make
Used time, when shell is placed on ground, ring-shaped rubber pad, which is squeezed, to be entirely retracted in annular groove, keep support portion inner cavity complete
It is in communication with the outside by gas port, stablizes the purpose for accelerating radiating rate and realize.
In the shell of above-mentioned helical-lobe compressor, pass through arc transition between the heat release hole and blowhole.Using
Above-mentioned design keeps entire exhaust process more smooth.
In the shell of above-mentioned helical-lobe compressor, the axis of the venthole extends along the vertical direction, and venthole is in
Taper, and the diameter of venthole gradually becomes smaller downwards.
In the shell of above-mentioned helical-lobe compressor, the filter vat and blowhole match, and filter vat passes through card
The mode connect is connected with support portion, and one end of the filter vat is stretched out blowhole and is located in support portion.It is set using above-mentioned
Meter, facilitates the dismounting of filter vat, to facilitate the cleaning of filter vat.
Compared with prior art, the shell of this helical-lobe compressor has the advantage that
1, support portion inner cavity, venthole and gas port composition one make the exhaust passage that housing cavity is in communication with the outside, to increase
Add the approach of enclosure interior and extraneous ventilation, thus effectively accelerate the radiating rate of enclosure interior, it is steady to improve compressor operating
It is qualitative.
2, by setting heat release hole in being obliquely arranged, be effectively reduced the impurity such as dust enter it is several in heat release hole
Rate can further prevent the impurity such as dust from entering in support portion secondly, filter vat is arranged in blowhole, thus effectively anti-
Only above-mentioned exhaust passage is blocked, and stablizes the purpose for improving radiating rate and realizes.
