The model utility content
The purpose of this utility model is in order to overcome the deficiency of existing horizontal single screw compressor, a kind of compact structure and economic vertical single screw air compressor to be provided.
A kind of vertical single screw air compressor of the utility model, comprise compressor pump, motor, cooling fan, with deaerator, control valve, control system and the electric system of forming complete machine, screw rod monosymmetric is provided with a pair of star-wheel that is meshed with screw rod, it is characterized in that motor vertically is installed on above the single screw compressor pump housing, make cooling fan, motor and compressor pump upper and lower settings and by same main shaft drives successively, cooling heat exchanger is contained in the cooling fan top, and the lower end cap of motor constitutes the upper end cap of compressor pump simultaneously.
Be provided with wind scooper between described cooling heat exchanger and the electric machine casing, be provided with between wind scooper and the electric machine casing at interval, cooling fan cools off cooling blast earlier again to cooling heat exchanger through the electric machine casing radiating fin.
Described wind scooper is installed on the upper end cap of motor.
The plain shaft envelope is installed between the lower end cap of described main shaft and motor.
The suction port of described compressor is positioned at the middle and lower part in compressor pump front, and relief opening is positioned at the middle and upper part at the compressor pump back side.
Described vertical single screw air compressor comprises compressor pump, motor, cooling fan, with the whole machine installation of deaerator, control valve, control system and the electric system of forming complete machine in two casings that main door and side door are only arranged, casing is connected with base by four screw rods on corner post.
The beneficial effects of the utility model are: because vertical structure, motor vertically is installed on above the single screw compressor pump housing, make cooling fan, motor and compressor pump upper and lower settings and by same main shaft drives successively, avoided the transmission loss of driving mechanism, only need an end cap between motor and the compressor pump, need not expensive dynamic seal apparatus; The setting of wind scooper can be simultaneously to electric machine casing and cooling heat exchanger cooling, and motor need not to be provided with cooling unit again; The utility model component are few, volume is little, reliability is high, compact structure, maintenance facility, and cost is low, are convenient to promote.
