Embodiment
Describe preferred implementation of the present invention in detail below in conjunction with accompanying drawing.
Embodiment 1
Referring to Fig. 1 and Fig. 2, shown in legend wherein: a kind of plane floatation bearing, precision for detection of pressure transducer 7, comprise a little suspension bearing, large suspension bearing, a communicating pipe 4 and a recharging oil device, described little suspension bearing comprises a small container 11, a displacement transducer 3 and a little movable support 12; Described large suspension bearing comprises a bulk container and a large movable support 22; Described recharging oil device comprises a fuel tank 51 and a upper oil pipe 52; Described displacement transducer 3 is located at respectively on described little movable support 12 and the large movable support 22; Described little movable support 12 and large movable support 22 are located at respectively the top of described small container 11 and bulk container 21; Described small container 11 and bulk container 21 are upper end open; The bottom that described small container 11 is connected with bulk container connected by described communicating pipe 4; Described large movable support 22 tops are provided with crossbeam 8; Described pressure transducer 7 is located on the described crossbeam 8; Described upper oil pipe 52 connects described fuel tank 51 and described communicating pipe 4.
The compression face of described small container 11 and bulk container 21 is the combination compression face that comprises seven compression faces.
The compression area of described bulk container 21 becomes the ratio of 100 times of amplifications with respect to the compression area of described small container 11.
Described fuel tank 51 is provided with oil return apparatus.
Described oil return apparatus comprises two scavenge pipes 53, little oil spilling pallet 54 and large oil spilling pallet 55, and described scavenge pipe 53 connects respectively the bottom of described fuel tank 51 and little oil spilling pallet 54 and large oil spilling pallet 55.
Described little oil spilling pallet 54 and large oil spilling pallet 55 are located at respectively the annular pallet of bulk container 21 bottoms of described small container 11.
Also be provided with a line strainer 56 on the described scavenge pipe 53.
The below introduces principle of work of the present invention.
Referring to Fig. 3, in theory, one heavily is positioned on the little movable support 12 for the counterweight 6 of 100Kg, because small container 11 is identical with liquid pressure in the bulk container 21, and the Area Ratio between them is 1:200, therefore the ratio of the pressure between the two is 1:200, the power that 20000kg should be arranged on the therefore large movable support 22, theoretical indicating value on the pressure transducer 7 should be 20000Kg, now automatically hydraulic oil is passed in communicating pipe 4 by upper oil pipe 52, pressure transducer 7 to be detected is positioned over the below of crossbeam 8, one heavily is positioned on the little movable support 12 for the counterweight 6 of 100Kg, pressure transducer 7 can show the measured value of a reality, and actual value and the theoretical value of sensor compared, and can obtain the precision of pressure transducer 7; Distance between 3 pairs of small containers 11 of displacement transducer and the little movable support 12 is carried out real-time tracking and is detected; When the oil pressure in small container 11 and the bulk container 21 was not enough, recharging oil device can in time carry out repairing, thereby has guaranteed the constant of the force value in the communicating pipe; And for the oil that overflows small container 11 and bulk container 21, little oil spilling pallet 54 and large oil spilling pallet 55 can be accepted, and get back in the fuel tank 51 by scavenge pipe 53, carry out utilization again, line strainer 56 can purify dust and the impurity that produces in the oil return process, has guaranteed the cleanliness without any pollution of hydraulic oil.
