Description
Technical field
The present invention relates to a kind of centrifugation unloading mechanism, especially compressors to be centrifuged unloading mechanism.
Background technique
Existing compressor requires unloading starting, and otherwise motor is easy to overload and burn out, and compression is usually realized with solenoid valve
Emptying is shut down in machine starting.However in practical work process, metal fillings, dirt are easily stuck in valve core of the electromagnetic valve in Compressor Pipes,
Make solenoid valve that can not close gas leakage even to damage, electromagnetic valve coil also easy burn-out, and wanted with the emptying of solenoid valve control compressor
It asks and installs relay on circuit additional, cause circuit complicated, cost is also increase accordingly.
Summary of the invention
The purpose of the present invention is to solve present in existing compressor, the easy card foreign matter gas leakage of solenoid valve is even damaged,
Circuit is complicated, and a kind of structure that is at high cost and providing is simple, easy to use, centrifugation unloading mechanism.
Technical solution
What the object of the invention was realized in:
A kind of centrifugation unloading mechanism, including crankpin seat, off-load centrifugation, centrifugation piston and reset spring, the centrifugation
Piston is arranged in crankpin seat, is provided with reset spring between the crankpin seat and centrifugation piston, the off-load from
Center is hinged on the crankpin seat, and off-load centrifugation has free end and a positioning end, the positioning end with it is described
Centrifugation piston contact, the free end under the action of positioning end with the appearance face contact of the crankpin seat.
Off-load centrifugation is off-load iron.
It is hinged that the crankpin seat with off-load Tie Tong crosses straight pin.
Lockwire is equipped between the crankpin seat, off-load iron and straight pin.
The present invention is centrifuged unloading mechanism, including crankpin seat, off-load iron, centrifugation piston, reset spring, straight pin and peace
Full locking wire.
The purpose that the present invention realizes compressor start, shuts down release interstage pressure, extends the service life of motor, belt,
A possibility that reducing overload relay tripping.Centrifugation unloading mechanism with crank axle is concentric installs, centrifugation unloading mechanism is with crank axle
Rotation, off-load iron by centrifugal force act on, overcome return spring force, off-load iron is swung out so that centrifugation piston and tappet to
Interior movement, tappet leave valve inside, and gas passage is closed, and compressor is in running order, when compressor shutdown, the contracting of off-load iron
It returns, spring will be centrifuged piston reset, and tappet opens valve inside, and gas passage is opened, gas outflow in Compressor Pipes.
Beneficial effect
Due to using technical solutions according to the invention, the disadvantages of solenoid valve failure is more, easy to damage, Er Qiejian are not only avoided
Change compressor circuit, reduces electric appliance cost.Using centrifugation feel trim actuator, structure is simple, and reliable effect ensure that compressor
Stable operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of centrifugation unloading mechanism one embodiment of the present invention.
Fig. 2 is the cross-sectional view of Fig. 1.
Fig. 3 is the structural schematic diagram for being centrifuged unloading mechanism Application Example.

Specific embodiment:
As shown in FIGS. 1 and 2 the present invention is centrifuged unloading mechanism, including crankpin seat 1, straight pin 2, lockwire 3, off-load iron 4, from
It is indecisive and changeable and fills in the composition such as 5 and reset spring 6, wherein off-load iron 4 is rotatably coupled on crankpin seat 1 by straight pin 2, from
Plug 5 of being indecisive and changeable is mounted in crankpin seat 1, also installs reset spring 6, reset spring 6 between crankpin seat 1 and centrifugation piston 5
One precompression of offer give centrifugation piston 5, and by be centrifuged piston 5 make the very tight outer surface for being attached to crankpin seat 1 of off-load.
As shown in figure 3, centrifugation feel trim actuator of the invention is mounted on the crank axle of compressor, when compressor operation,
It is centrifuged unloading mechanism to rotate with crank axle 7, off-load iron 4 is acted on by centrifugal force, overcomes 6 power of reset spring, and off-load iron 4 is put outward
Dynamic, so that centrifugation piston 5 and tappet 9 move inward, tappet 9 leaves valve inside, and gas passage is closed, and compressor is in work
State, when compressor shutdown, off-load iron 4 is retracted, and spring 6 is resetted piston 5 is centrifuged, and tappet 9 opens valve inside 12, compressor pipe
Road gas, which enters from pipeline pressure import 16 from pipeline pressure discharge outlet 17, to flow out.
