Specific embodiment
The embodiments of the present invention are described further below for attached drawing:
As shown, a kind of contactless grease liquid level sensor, including oil drum 1, it further include auxiliary follow up piston 2, magnet ring 3
And magnetic switch 4, the auxiliary follow up piston 2 can slide up and down along the inner sidewall of oil drum 1 and seal against each other cooperation, described
Spring 5 is equipped between the upper end of auxiliary follow up piston 2 and the top of oil drum 1, under the lower end of the auxiliary follow up piston 2 and oil drum 1
It is grease cavity 6 between side, the auxiliary follow up piston 2 is equipped with magnet ring 3, and the lower end or outside of the oil drum 1 are opened equipped with magnetism
Close 4, the magnetic switch 4 is mutually isolated with magnet ring 3 and corresponding matching, the auxiliary follow up piston 2 close to magnetic switch 4, it is described with
Magnet ring 3 in piston 2 triggers the magnetic switch 4 by magnetic strength.It is provided with auxiliary follow up piston in the oily cylinder of oil pump, is servo-actuated and lives
Plug moves up and down in oily cylinder with the variation of grease volume, when auxiliary follow up piston is moved to low oil level position, is encapsulated in piston
Interior magnet ring triggering magnetic switch movement, issues low oil level alarm signal.According to above scheme, which is passed
Sensor realizes that contactless low oil level is alarmed by the combination of magnet ring and magnetic switch, sensitive, high reliablity, sealing performance
It is good, risk of leakage is not present.
In the present invention, the lower end of the auxiliary follow up piston 2 is equipped with groove, and the magnet ring 3 is built in the groove 7
It is interior, the outer end of the magnet ring 3 and it is located at 7 mouthfuls of groove places equipped with airtight and watertight padding 8.By the way that groove 7 is arranged on auxiliary follow up piston, magnetic
Ring is built in groove and is sealed by airtight and watertight padding, and when auxiliary follow up piston is close to magnetic switch, magnet ring can trigger magnetism
Alarm is realized in switch motion, and when liquid level improves, oil pressure just will push auxiliary follow up piston and rise and squeeze spring, using airtight and watertight padding
