The testing device has simple operation, high accuracy and strong practicality.
Description
Technical field
The utility model relates to a kind of test unit, especially a kind of liquid level gauge test unit.
Background technology
Along with development of science and technology and to the raising of measuring requirement, high-precision liquid level gauge is used increasingly extensive, and as measuring the float-ball type liquid level gauge of oil tank level, range is 4m, and the limits of error only are ± 0.5mm.Traditional liquid level gauge test unit has two classes: a class is the water tank test unit, and the general 0-2m of range adopts straight steel ruler to measure the limits of error ± 0.35mm; One class is a simulation liquid level method, and general 0-10m of range or 0-20m adopt steel tape to measure, the mm of the limits of error ± (0.3+0.2L).And when test requires the limits of error of test unit should be no more than 1/4 of the tested liquid level gauge limits of error.As seen, for above-mentioned liquid level gauge, traditional liquid level gauge test unit can't meet the demands.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of accurate float-ball type liquid level gauge test unit, and this test unit can improve measuring accuracy, can satisfy the testing requirements of high precision float-ball type liquid level gauge.
For achieving the above object, the technical solution adopted in the utility model is: a kind of accurate float-ball type liquid level gauge test unit, the testing table that comprises the scalable level is fixed on the fixed support on the testing table, is characterized in: this device also comprises main scale, vernier scale, by the ball float steady arm that transparent organic glass is made, main scale is fixed on the fixed support, and vernier scale is stuck on the main scale by the chute above it, and can move along main scale, the ball float steady arm is fixedly mounted on the vernier scale.
The right-hand member of vernier scale is provided with a micro-adjusting mechanism, and micro-adjusting mechanism is connected with vernier scale by a trimming bolt, can be in the same moved further of vernier scale; Main scale is long to be 4.3m; The resolution of vernier scale is 0.02mm.
The beneficial effects of the utility model are: this test unit is simple to operate, and the accuracy height is practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1, accurate float-ball type liquid level gauge test unit of the present utility model comprises testing table 1, fixed support 2, main scale 3, vernier scale 4, micro-adjusting mechanism 5, ball float steady arm 6.
This device likeness in form one is huge vernier caliper, and main scale 3 long 4.3m are horizontally fixed on screw 8 on the fixed support 2 of testing table 1, testing table 1 scalable level.The vernier scale 4 that resolution is 0.02mm is installed on the main scale 3, and vernier scale 4 is the slot type structure, is stuck on the main scale 3, can move freely on main scale 3.In order accurately to locate the position of liquid level gauge ball float, design a ball float steady arm 6, the slot type structure that this ball float steady arm 6 is made for transparent organic glass, be fixedly mounted on the vernier scale 4, place ball float steady arm 6 fixing ball float during test, just realized the integral structure of ball float and vernier scale 4, guaranteed that ball float and vernier scale 4 all can not change the position with moved further when test process and backhaul, satisfied the testing requirements of the liquid level gauge error of indication and return difference.In addition, at micro-adjusting mechanism 5 of right-hand member connection of vernier scale 4, this micro-adjusting mechanism 5 also adopts the slot type structure, is connected with vernier scale 4 by a trimming bolt 7, can be in vernier scale 4 same moved further.After vernier scale 4 positions are determined, can micro-adjusting mechanism 5 is fixing with main scale 3 by holding screw 9, by regulating trimming bolt 7, can realize fine setting again to vernier scale 4, finally determine the exact position of vernier scale 4.
This precision float-ball type liquid level gauge test unit resolution is 0.02mm, and the limits of error ± 0.1mm can satisfy the testing requirements of high precision float-ball type liquid level gauge.Through practice, this test unit is simple to operate, and the accuracy height is practical.
