The device can automatically and timely detect blocking of the oil suction filter in a working process, has an alarm indication function, can conduct audible and visual alarm indication on the blocking of the oil suction filter in the working process, can effectively prevent the hydraulic pump from sucking air, can continuously supply oil through other devices in a bypassing manner to prevent the hydraulic pump from sucking the air when the oil suction filter is blocked, and is simple in structure, reliable in working, low in cost, and convenient to mount, use and maintain.
Description
Technical field
The utility model relates to the hydraulic transmission and control field, relates in particular in the hydraulic transmission and control system a kind of oil absorption filter and stops up and automatically detect and bypass continuous oil supply device.
Background technique
Along with the development of modern industry, hydraulic transmission and control system are widely used in the national economy all trades and professions such as lathe, engineering machinery, agriculture and forestry machinery, space flight and aviation.For the protection oil hydraulic pump, oil absorption filter is installed on the inlet line of oil hydraulic pump all usually in hydraulic system; oil absorption filter is immersed in bottom fuel tank; operator occur to stop up to oil absorption filter and are difficult in time realize; if in working procedure, oil absorption filter occur to stop up and will cause the oil hydraulic pump oil suction smooth or cause emptying phenomenon; this will cause system to produce cavitation erosion and powerful noise on the one hand; can cause also that on the other hand system's fuel feeding is not smooth, affects the normal operation of hydraulic equipment.
The model utility content
Its purpose of the utility model just is to provide a kind of oil absorption filter to stop up and automatically detects and bypass continuous oil supply device, this device can detect automatically to blockage phenomenon in the oil absorption filter working procedure, have sound, light warning obstruction deixis, can realize the bypass continuous oil supply by other device when oil absorption filter occurs to stop up, effectively prevent the generation of oil hydraulic pump emptying phenomenon.
The technological scheme that the utility model is taked to achieve these goals, comprise fuel tank, oil absorption filter, oil hydraulic pump, relief valve, butterfly valve, jam detection switch, jam detection tutorial light, jam detection alarm buzzer, power supply, wherein oil absorption filter is arranged on the main oil suction road of oil hydraulic pump; The other fuel sucking pipe that connects on the inlet line of oil hydraulic pump; The side connects butterfly valve is installed on fuel sucking pipe; Utilize a continuous motion stem that butterfly valve is connected with the jam detection switch; The jam detection alarm buzzer is in parallel with the jam detection tutorial light, and rear branch road in parallel is connected with the jam detection switch, and DC electrical source is to circuit supply.
Compared with prior art, this device has advantages of following: detect automatically in time, can carry out automatically in time detecting to blockage phenomenon in the oil absorption filter working procedure; Have alarm indication function, can carry out sound, light warning indication to blockage phenomenon in the oil absorption filter working procedure; Effectively prevent the generation of oil hydraulic pump emptying phenomenon, when oil absorption filter occurs to stop up, can by other device bypass continuous oil supply, prevent the generation of oil hydraulic pump emptying phenomenon; Apparatus structure is simple, reliable operation, and cost is low, installation, use, easy to maintenance.
Description of drawings
Fig. 1 is the fundamental diagram of this device.
Embodiment
Embodiment as shown in Figure 1, comprises fuel tank 1, oil absorption filter 2, oil hydraulic pump 3, relief valve 4, butterfly valve 5, jam detection switch 6, jam detection tutorial light 7, jam detection alarm buzzer 8, power supply 9.Oil absorption filter 2 is arranged on the main oil suction road of oil hydraulic pump 3; The other fuel sucking pipe that connects on the inlet line of oil hydraulic pump 3; The side connects butterfly valve 5 is installed on fuel sucking pipe; Utilize a continuous motion stem that butterfly valve 5 is connected with jam detection switch 6; Jam detection alarm buzzer 8 is in parallel with jam detection tutorial light 7, and rear branch road in parallel is connected with jam detection switch 6, and DC electrical source 9 is to circuit supply.
The systemic-function explanation: as shown in drawings, main functional modules comprises that oil absorption filter stops up automatic measuring unit, acoustooptic alarm stops up indicating circuit and bypass continuous oil supply device.When oil absorption filter 2 normal operations do not occur to stop up, oil hydraulic pump 3 from fuel tank through main oil suction road and oil absorption filter 2 oil suctions, this moment, butterfly valve 5 cut out, reset response due to spring, jam detection switch 6 is in off state, testing circuit is in turnoff state, and jam detection tutorial light 7 does not work, and jam detection alarm buzzer 8 does not send chimes of doom.When oil absorption filter 2 occurs to stop up, oil hydraulic pump 3 from fuel tank through main oil suction road and oil absorption filter 2 oil suctions not smooth, butterfly valve 5 is opened, and oil hydraulic pump 3 through butterfly valve 5 and the oil suction of bypass fuel sucking pipe, is realized the bypass repairing from fuel tank, thereby avoid the generation of emptying phenomenon, and realize to system's continuous oil supply, drive 6 actions of jam detection switch by connecting rod when butterfly valve 5 is opened closed, this moment, the testing circuit closure formed the loop, jam detection tutorial light 7 is bright, and jam detection alarm buzzer 8 sends chimes of doom.
System uses operational instruction: when oil absorption filter 2 normal operations did not occur to stop up, jam detection tutorial light 7 did not work, and jam detection alarm buzzer 8 does not send chimes of doom, oil hydraulic pump oil suction normal operation; When oil absorption filter 2 occured to stop up, jam detection tutorial light 7 was bright, and jam detection alarm buzzer 8 sends chimes of doom, and oil hydraulic pump is from bypass oil suction work, and will in time clean or change oil absorption filter 2 this moment.
