Speed, it is accurate, continuously run and baroque direction is developed.It is to ensure it that on-line monitoring is carried out to accumulator and hydraulic test
Safe and stable, long period, at full capacity, the important measure of high-performance, high accuracy, low cost operation.
Existing piston accumulator internal piston displacement is invisible, can not be detected, therefore piston accumulator is in liquid
When being used in pressure system, working condition can not possibly realize on-line monitoring.Using which kind of mode by piston accumulator internal piston
Misalignment is reflected, and piston accumulator is realized on-line monitoring, is the direction studied in the industry.Current industry is existing various
Open one's minds, but have complex structure problem, while the installation inconvenience that also seems, relatively costly.
The content of the invention
The utility model is to solve the above-mentioned deficiency existing for prior art, there is provided one kind is lived using magnetic induction measurement
Plug displacement, simple structure, piston accumulator easy for installation.
The utility model is realized to solve above-mentioned technical problem using following technical scheme：
A kind of piston accumulator of utilization magnetic induction measurement piston displacement, including cylinder body, gas port end cap, piston, hydraulic fluid port
End cap, magnetic strength collector.The cylinder body, gas port end cap, piston form air cavity；The cylinder body, piston, hydraulic fluid port end cap form oil
Chamber.The magnetic strength collector is installed on the cylinder body outside, correspondence piston whole stroke in the cylinder body.
The piston air cavity side end face is embedded with some permanent magnets, is distributed in the piston periphery.Permanent magnets are equal described in polylith
Be distributed in the piston periphery, it is therefore an objective to no matter the piston how axial rotation, always there are the permanent magnets to adopt near the magnetic strength
Storage, so as to avoid making because of the piston axial rotation permanent magnets away from the magnetic strength collector, influence sensing detection.
The magnetic strength collector includes support, Magnetic Sensor, soft magnetism, communication cable, the Magnetic Sensor uniform intervals row
Loaded on the support, and near the cylinder surface, the soft magnetism mounted in Magnetic Sensor outside, and with the Magnetic Sensor
Correspond.The soft magnetism is answered with the permanent magnets pole pair, plays magnet accumulating cap, forms the signal magnetic line of force.
The course of work：The cylinder body is magnetized because of the permanent magnets, but density of line of magnetic force is closer to the permanent magnets
Stronger, the permanent magnets are formed about strong magnetic cluster.When hydraulic system pressure change move up and down the piston when, it is described forever
Magnetic patch is also moved up and down with the piston, and the strong magnetic cluster produced by the permanent magnets is equally moved up and down with the piston.By institute
The strong magnetic cluster of that stock for stating permanent magnets formation senses the Magnetic Sensor, the Magnetic Sensor is detected the piston and moves up and down
Situation.To make the strong magnetic cluster high efficiency of that stock formed by the permanent magnets sense the Magnetic Sensor, then will by the soft magnetism
The strong magnetic cluster of that stock is gathered into the signal magnetic line of force, to improve detection sensitivity.
The Magnetic Sensor equip in the support number, determine the precision of sensing detection, the magnetic equipped is passed
Sensor quantity is more, and interval is smaller, and the precision for sensing detection is higher.
The Magnetic Sensor connects the communication cable, and described piston displacement information transfer for obtaining to computer etc. is processed
Display terminal.
The utility model has an advantageous effect in that：Can obtain in real time piston accumulator internal piston displacement, immediately
The information such as speed and instantaneous acceleration, realizes piston accumulator on-line monitoring function；Simple structure, easy for installation simultaneously, into
This is relatively low.
