Abstract
The invention relates to a dry gas seal dynamic and static testing device which comprises a work bench, a base and a motor. One end of the work bench is fixedly provided with the base, the motor is coaxially arranged in the base, the end portion of the motor is coaxially provided with a connection shaft, a pair of supporting plates are horizontally arranged on the work bench corresponding to the base in a sliding mode, and the opposite outer sides of the two supporting plates are respectively and movably provided with a check block. According to the dry gas seal dynamic and static testing device, a testing cavity is fixed on the work bench through the supporting plates and the check bocks and is located in the axial direction and in the radial direction, and the problem that the connection shaft bears radial force is effectively solved. The dry gas seal dynamic and static testing device is simple in structure, scientific and reasonable in design, capable of effectively prolonging the service life of the connection shaft, particularly suitable for a double-chamber testing cavity, and capable of improving testing work efficiency.
Description
Technical field
The invention belongs to dry gas seals technical field, specifically, is a kind of dry gas seals static and dynamic test device.
Background technology
Dry gas seals assembly must carry out static and dynamic test after production is complete, its objective is its sealing property of test, existing static and dynamic test device comprises worktable and motor, first dry gas seals assembly is arranged in the cavity of a cylindrical structure, and then the output shaft by coupling shaft and motor links together by cavity.
In said structure, cavity is supported by coupling shaft completely, thus coupling shaft to bear radial force large, thereby affect the serviceable life of coupling shaft.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of simple in structure, dry gas seals static and dynamic test device of improving serviceable life and work efficiency is provided.
The solution of the present invention is achieved in that
A kind of dry gas seals static and dynamic test device, comprise worktable, pedestal and motor, described worktable one end is fixed with pedestal, in this pedestal, be coaxially installed with motor, the coaxial coupling shaft of installing in end of this motor, the worktable of the corresponding described pedestal a pair of back up pad that is laterally slidably installed, the relative outside of two back up pads is movably installed with respectively block.
And described back up pad is a Rectangular Plate Structure, its upper center is shaped with one can hold the arc groove of testing cavity, and this arc groove bottom connection is shaped with a rectangular recess, and described arc groove both sides are connected with respectively block by screw.
And described worktable upper surface is shaped with a pair of elongated slot.
Advantage of the present invention and good effect are:
This testing table is fixed on test cavity on worktable by back up pad and block, to it axially and radial location, has effectively solved the problem that coupling shaft bears radial force.The present invention is simple in structure, design science is reasonable, effectively improves the serviceable life of coupling shaft, is especially applicable to the test cavity of dual cavity, can improve test and test work efficiency.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is that the A of back up pad in Fig. 2 is to view.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment, the invention will be further described.
A static and dynamic test device, as shown in Figure 1 and Figure 2, comprises worktable 6, pedestal 1 and motor 2, and described worktable one end is fixed with pedestal, in this pedestal, is coaxially installed with motor, the coaxial coupling shaft 3 of installing in end of this motor.
Innovative point of the present invention is:
The worktable of corresponding described pedestal is laterally shaped with a pair of elongated slot 7, a pair of back up pad 5 is laterally slidably installed in this elongated slot, the relative outside of two back up pads is movably installed with respectively the block 4 of limit assay cavity (not shown) axially-movable, and this block is rectangular configuration.
Described back up pad be a Rectangular Plate Structure as shown in Figure 3, its upper center is shaped with one can hold the arc groove 8 of testing cavity, this arc groove bottom connection is shaped with a rectangular recess 9, described arc groove both sides are connected with respectively block 4 by screw, the axially-movable that the rotation by block can limit assay cavity.
Using method of the present invention, step is as follows:
Step 1, is first placed on test cavity in the arc groove of two back up pad upper ends;
Step 3, controls static and dynamic test device by control module, thus the testing goal of completing.
The length of different tests cavity not etc., is not therefore adjusted the distance between two back up pads by the elongated slot being shaped with on worktable.
This test unit is fixed on test cavity on worktable by back up pad and block, to it axially and radial location, has effectively solved the problem that coupling shaft bears radial force.The present invention is simple in structure, design science is reasonable, effectively improves the serviceable life of coupling shaft, is especially applicable to the test cavity of dual cavity, can improve test and test work efficiency.
It is emphasized that; embodiment of the present invention is illustrative; rather than determinate; therefore the present invention includes and be not limited to the embodiment described in embodiment; every other embodiments that drawn by those skilled in the art's technical scheme according to the present invention, belong to the scope of protection of the invention equally.
