In casing.The axle is provided with balance weight.The junction of the casing and fixed scroll and the end cap is provided with sealing gasket.
The sealing gasket includes stainless steel belt and is arranged on the rubber of two end faces of stainless steel belt.It is described close
Packing can completely cut off extraneous air, high pressure chest and low pressure chamber simultaneously.
In one of the embodiments, the screw compressor sealing structure also includes air inlet and exhaust outlet.The machine
Shell is provided with air inlet.The end cap is provided with exhaust outlet.The exhaust outlet connects with the high pressure chest, the air inlet and institute
State low pressure chamber connection.
In one of the embodiments, the stainless steel belt is provided with convex epirelief.
Advantages of the present invention and its advantage：
（1）The present invention will be sealed at the two of existing compressor and handled respectively, make single treatment into；The present invention one is close
Packing energy while sealing low pressure chamber and high pressure chest.
（2）The left end face of the fixed scroll of the present invention and the flange face of casing are in same plane, it is only necessary to a sealing
Pad so that cost of the present invention is low, simple in construction, small volume.
（3）The sealing gasket of the present invention includes stainless steel belt and rubber, and stainless steel belt is provided with convex epirelief, sealing effectiveness
It is good, and sealing gasket can completely cut off extraneous air, high pressure chest and low pressure chamber simultaneously.
