Description
Technical field
The accessory hydraulic cylinder that the utility model relates in the civil engineering machine excavator is manufactured field, specifically refers to the magnetostrictive displacement sensor protective casing.
Background technology
Hydraulic cylinder is hydraulic jack, extensively is used in the civil engineering machines such as bagger, excavator, shovel loader, street roller.The KYB that at present enterprise of the leading supporting hydraulic pressure spare and accessory parts of domestic civil engineering machine is German Bosch BOSCH-REXROTH, Japan, Kawasaki, only more, the enterprise such as Toshiba.Magnetostrictive liquid level sensor is high precision, the ultralong-stroke Absolute position measurement sensor that adopts magnetostriction principle to manufacture.This product is comprised of pulsing circuit, waveguide wire, echoed signal unit, structural member and protective casing; there are the characteristics such as precision is high, stability is reliable, the life-span is long, the way of output easy for installation, multiple is available; it not only can measure the straight-line displacement of moving object, and can provide displacement and the velocity simulate signal of moving object.Owing to adopting noncontact volume metering system, sensor performance is stable, long service life, and the multiple way of output is selective.Thereby be widely used in the industry equipment such as petrochemical complex, food, water treatment, environmental protection, agricultural chemicals, papermaking, reservoir, dyestuff, oil pressure machinery.
The magnetostrictive displacement sensor protective casing that MTS Systm Corp. of company of existing magnetostrictive displacement sensor protective casing and global first hand developing magnetostriction measurement technology provides is all that screw-type connects, protective casing for short measurement stroke magnetostrictive displacement sensor (2000～3000mm) adopts screw-type to connect the too large problem that do not have, reach 6000mm when measuring stroke over 3000mm, while even surpassing 6000mm, protective casing adopts the screw-type connection will cause screw thread seriously to be killed because of unbalance loading, cause protective casing and connected parts to scrap, bring great inconvenience to the assembling protection simultaneously.Existing telescopic displacement sensor adopts non-contact technology to be connected with hydraulic cylinder mostly simultaneously, causes both to contact bad, easily is subject to the impact of temperature and pressure, can not bear the impact of high temperature, high pressure and high vibration, and it is very little that the hydraulic cylinder made bears pressure.
