Embodiment
Further specify below in conjunction with accompanying drawing.
Shown in Fig. 1~3; this air compressor automatic oiling protective gear comprises oil level control gear and fuel reserve tank 20; the oil level control gear contains casing 10; on casing 10 1 sides; the bottom is respectively equipped with tracheae 13 and is communicated with the oil pipe 14 of air compressor crankcase 30; casing 10 inboards are provided with the support 7 of two symmetries; 7`; level is installed guide shaft 4 on these two supports; guide shaft 4 middle part stator rings 5 and mercury switch frame 3; the periphery of guide wheel 5 connects keg float 6 by connecting rod; oiling mercury switch 1 and protection mercury switch 2 are installed on the mercury switch frame 3, and protection mercury switch 2 is connected in the control loop of air compressor by lead 11.Above the casing 10 of oil level control gear opening is arranged, this opening is installed sealing gasket 8 and case lid 9.
Solenoid valve 23 is installed in the bottom of fuel reserve tank 20, the top of solenoid valve 23 seals with dividing plate 24, the filler opening of solenoid valve 23 and fuel reserve tank 20 are communicated with, the oil outlet of solenoid valve 23 connects oil filler pipe 21, oil filler pipe 21 connects a threeway 22, an outlet of threeway 22 connects the tracheae 13 of oil level control gear casing 10, another outlet of threeway 22 connects the oil hole of air compressor crankcase 30, oiling mercury switch 1 is connected by lead 12 in the control loop of solenoid valve 23, and parts shown in the figure 25 cover for the hydraulic fluid port that is marked with of fuel reserve tank 20.
In the present embodiment; oiling mercury switch 1 is used for controlling oiling; protection mercury switch 2 is used for controlling oil cutting-off protection; see figures.1.and.2; the tip side of the tip side of oiling mercury switch 1 and protection mercury switch 2 is installed on the contrary, and the axis of oiling mercury switch 1 and the angle of pasta are less than the angle of protection mercury switch 2 with pasta.Like this, during oil level normal (keg float 6 is in a oil level), 2 conductings of protection mercury switch, oiling mercury switch 1 disconnect; When oil level drops to the b oil level, protection mercury switch 2 and all conductings of oiling mercury switch 1; When oil level dropped to the c oil level, 1 conducting of oiling mercury switch, protection mercury switch 2 disconnected.
With reference to Fig. 4, the electrical control part of present embodiment comprises oiling mercury switch 1, protection mercury switch 2, solenoid valve 23 and contactor Q.Wherein, the B that connects three phase mains after the normally-closed contact J1 series connection of the coil of protection mercury switch 2, contactor Q and contactor Q mutually with C mutually, three normally opened contact J11, the J12 of contactor Q, J13 are connected to respectively in three supply lines of motor M; Oiling mercury switch 1 and solenoid valve 23 are series between the A phase and ground of three phase mains.
Fig. 5 represents its installation and user mode.The oil level control gear is installed on air compressor crankcase 30 1 side lower parts, and fuel reserve tank 20 is installed on the top of air compressor crankcase 30, and parts shown in the figure 31 are the oil level glass of crankcase 30.
The working principle of this air compressor automatic oiling protective gear is as follows:
When air compressor works well; keg float 6 in the oil level control gear is in (oil level of crankcase and control box is consistent) on a oil level; be installed in the oiling mercury switch 1 on the guide shaft 4 and protect mercury switch 2 to be subjected to the effect of keg float 6; be adjusted on the left-oblique position; because the axis of oiling mercury switch 1 and the angle of pasta are less than the angle of protection mercury switch 2 with pasta; oiling this moment mercury switch 1 is in off state; protection mercury switch 2 is on state, and air compressor runs well.When oil level drops to b; keg float 6 sinks to changing the angle of mercury switch; 1 conducting of oiling this moment mercury switch; solenoid valve 23; valve open; fuel reserve tank 20 replenishes an amount of oil by the oiling passage to crankcase, (protect mercury switch 2 still to be on state this moment, so air compressor still runs well).When keg float 6 floats to a oil level, oiling mercury switch 1 disconnects, and stops oiling.
If air compressor is in operation process, appearance can't fuel feeding or fuel tank failure and special such as break, when keg float 6 drops to the c oil level with oil level; mercury switch is tilted to the right, and protects this moment mercury switch 2 to disconnect contactor Q dead electricity; current supply circuit disconnects, and air compressor shuts down.
