Abstract
The utility model discloses a centrifugal unloading mechanism which comprises a crank pin base, an unloading centrifugal part, a centrifugal piston and a reset spring. The centrifugal piston is arranged inside the crank pin base, the reset spring is arranged between the crank pin base and the centrifugal piston, and the unloading centrifugal part is hinged to the crank pin base. The unloading centrifugal part is provided with a free end and a positioning end, wherein the positioning end is contacted with the centrifugal piston, and the free end of the unloading centrifugal end is contacted with the outer surface of the crank pin base under the action of the positioning end. According to the centrifugal unloading mechanism, the purpose that interstage pressure is released when a compressor is started and stopped is achieved, the service life of a motor and a belt is prolonged, and the possibility of tripping of an overload relay is reduced.
Description
Technical field
The utility model relates to the centrifugal unloading mechanism of a kind of centrifugal unloading mechanism, particularly compressor.
Background technique
Existing compressor requires unloading to start, otherwise motor easily overload burn out, realize compressor start, shut down emptying with solenoid valve usually.Yet in the practical work process, metal fillings, dirt very easily are stuck in valve core of the electromagnetic valve in the compressor pipeline, make solenoid valve can't close gas leakage even damage, electromagnetic valve coil is easy burn-out also, and with installing relay additional on the electromagnetic valve compressor emptying requirement circuit, cause the circuit complexity, cost is corresponding increase also.
Summary of the invention
The purpose of this utility model exists in order to solve in the existing compressor, and solenoid valve easily blocks foreign matter gas leakage even damages, circuit complexity, the high and unloading mechanism a kind of simple in structure, easy to use, centrifugal that provides of cost.
Technological scheme
The utility model purpose is achieved in that
A kind of centrifugal unloading mechanism, comprise crankpin seat, the centrifugal son of off-load, centrifugal piston and Returnning spring, described centrifugal piston is arranged in the crankpin seat, be provided with Returnning spring between described crankpin seat and the centrifugal piston, the centrifugal son of described off-load is hinged on the described crankpin seat, the centrifugal son of this off-load has free end and positioning end, and described positioning end contacts with described centrifugal piston, and described free end contacts with the outer surface of described crankpin seat under the effect of positioning end.
The centrifugal son of described off-load is off-load iron.
It is hinged that straight pin is crossed by described crankpin seat and off-load Tie Tong.
Between described crankpin seat, off-load iron and straight pin, be provided with lockwire.
The centrifugal unloading mechanism of the utility model comprises crankpin seat, off-load iron, centrifugal piston, Returnning spring, straight pin and lockwire.
The utility model realized compressor start, shut down the purpose that discharges interstage pressure, prolonged the life-span of motor, belt, reduces the possibility of overload relay tripping operation.Centrifugal unloading mechanism is installed with crankshaft is concentric, and centrifugal unloading mechanism rotates with crankshaft, and off-load iron is subjected to centrifugal action; overcome Returnning spring power, off-load iron is outwards swung, and makes centrifugal piston and tappet move inward; tappet leaves valve inside, and gas channel is closed, and compressor is in running order; during compressor shutdown; off-load iron withdrawal, spring be centrifugal piston reset, tappet unseat the valve core; gas channel is opened, and gas flows out in the compressor pipeline.
Beneficial effect
Owing to adopted technological scheme described in the utility model, not only avoid shortcomings such as solenoid valve failure is many, fragile, and simplified compressor circuit, reduced the electrical equipment cost.Adopt centrifugal feel trim actuator, simple in structure, reliable effect has guaranteed compressor stable operation.
