Description
Technical field
The invention belongs to air compressor machine technical field, and in particular to a kind of fuel-starvation protection device for air compressor.
Background technology
Air compressor machine has two big types, and one kind is screw type, and another kind is piston-type, and wherein piston type air compressor is because of its price
It is cheap, easy to maintenance and widely used by enterprise, piston type air compressor using when due to phase mutual friction between parts produce and make an uproar
Sound, needs to add lubricating oil to air compressor machine primary lubricant system, air compressor machine oil pump is arranged in crankcase, and existing to reduce noise
Air compressor machine lacks the device of oil mass in observation crankcase, and when air compressor machine works, to understand the oil mass in crankcase, staff needs
Crankcase case lid is opened to be checked, it is troublesome in poeration, and oil mass is checked not in time, it frequently can lead to need the lubrication of fuel feeding
System even results in whole babinet damage because oil starvation causes piston and cylinder, connecting rod and bent axle machine bearing to burn out or stuck, fracture
It is bad.
The content of the invention
, can autostop when oil mass is very few in case it is an object of the invention to provide one kind easy to oil mass in observation crankcase
Fuel-starvation protection device for air compressor.
A kind of fuel-starvation protection device for air compressor of technical solution of the present invention, including the internal tubular oil box with cavity, institute
The side for stating oil box is equipped with the through hole connected with crankcase side wall, and oil shortage protector, the oil starvation are equipped with the oil box
Protector includes support plate, and the support plate is fixed on oil box upper end, support plate bottom be equipped with coaxial ring baffle and
Switch base, the lower edge of the ring baffle are less than the lower edge of switch base, and ring baffle is arranged on around switch base, described
A magnet contact-making switch is equipped with switch base, the magnet contact-making switch is connected with conducting wire, and the conducting wire is circumscribed with air compressor machine
Motor, the lower end center position of the switch base are equipped with guide post, and the floating ball that is magnetic, the magnetism floating ball are arranged on the guide post
Side of the upper end away from through hole be equipped with buoy, gap of the buoy between switch base and ring baffle upwardly extends and passes through
Outside perforating branches fagging to oil box, magnetic floating ball upper end be further opened with the matched seal groove of ring baffle, in the seal groove
Filled with sealing ring.
Preferably, a kind of fuel-starvation protection device for air compressor of the present invention, the support plate upper end are protected equipped with buoy
Cover, the side of the buoy protective cover away from crankcase are arranged to transparent scale plate, and it is transparent that the buoy upper end is equipped with a direction
The pointer of scale plate.
Preferably, a kind of fuel-starvation protection device for air compressor of the present invention, the magnetism floating ball include housing and permanent magnetism
Iron, the permanent magnet are arranged in housing close to one end of switch base.
Preferably, a kind of fuel-starvation protection device for air compressor of the present invention, the guide post lower end are equipped with catch.
Magnet contact-making switch described in technical solution of the present invention is to control the operation of air compressor machine, due to oil box and bent axle
Case connects, and when oil mass is sufficient in crankcase, magnetic floating ball is located at guide post topmost, seal groove and ring baffle fitted seal, this
When buoy be located at highest order, under the action of magnetic floating ball, magnet contact-making switch closure, compressor operation, with air compressor machine work
Make the extension of time, oil mass declines in crankcase, and when oil mass declines to a certain extent in crankcase, magnetic floating ball is also under
Fall, buoy moves down, and Fuel Oil Remaining in crankcase can be read from scale plate, and when magnetic floating ball continues to decline, magnet contact is opened
Close is influenced less and less by the magnetic field that magnetic floating ball produces, until magnet contact-making switch disconnects, air compressor machine is stopped.
The technology of the present invention beneficial effect：
Technical solution of the present invention sets buoy in magnetic floating ball upper end by setting magnetic floating ball, oil mass in crankcase
When sufficient, magnetic floating ball is located at guide post upper end, and being produced magnetic field by magnetic floating ball is influenced, magnet contact-making switch closure, air compressor machine
Normal operation, oil mass is reduced in crankcase, and magnetic floating ball falls, and buoy moves down, and can easily know bent axle by buoy mark
Oil mass in case, even if lubricating oil cannot be added in time, can also make air compressor machine be stopped, avoid under the control of magnetic floating ball
Air compressor machine causes damage because oil starvation is run.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention,
Fig. 2 is enlarged diagram at A in Fig. 1.
Embodiment
For ease of skilled artisan understands that technical solution of the present invention, in conjunction with Figure of description to the technology of the present invention side
Case is described further.
Referring to Fig. 1 and Fig. 2, a kind of fuel-starvation protection device for air compressor of the present invention, including the internal cylinder with cavity
Shape oil box 2, the side of the oil box 2 are equipped with the through hole connected with 1 side wall of crankcase, and being equipped with oil starvation in the oil box protects
Device is protected, the oil shortage protector includes support plate 4, and the support plate 4 is fixed on 2 upper end of oil box, and 4 bottom of support plate is equipped with
Coaxial ring baffle 5 and switch base 3, the lower edge of the ring baffle 5 are less than the lower edge of switch base 3, and ring baffle 5 is set
Put around switch base 3, be equipped with a magnet contact-making switch 6 in the switch base 3, the magnet contact-making switch 6, which is connected with, leads
Line 7, the conducting wire 7 are circumscribed with the motor of air compressor machine, and the lower end center position of the switch base 3 is equipped with guide post 8, the guide post
Be arranged the floating ball 9 that is magnetic on 8, side of the upper end away from through hole of the magnetism floating ball 9 is equipped with buoy 10, the buoy 10 from
Gap between switch base 3 and ring baffle 5 upwardly extends and runs through outside support plate 4 to oil box 2, and magnetic 9 upper end of floating ball is also opened
