[0002] Mechanical seals belong to one of the precision and relatively complex mechanical basic components, and are key components of various equipment such as pumps, reaction synthesis kettles, turbine compressors, and submersible motors. After being processed, it is necessary to conduct pressure testing on itself to judge the quality status of the finished product.

[0003] In the existing seal testing positioning area, it is directly in the pressure application working area. In case of improper operation by personnel, accidents are extremely likely to occur, and the safety is poor. Therefore, a mechanical seal pressure testing device is proposed.

[0010] Specifically, a slide rail is arranged at the center position of the top surface of the test bench through a reserved groove, and the positioning frame is slidably connected to the slide rail through a bottom slider.

[0012] Specifically, the driving end of the hydraulic cylinder is connected to the pressure block, and clamping blocks are arranged on one side of the first cylinder and the second cylinder, and the driving ends of the first cylinder and the second cylinder are connected to the clamping blocks.

[0013] By adopting the above technical solution, the pressure block is driven by the hydraulic cylinder to descend to press the seal, so as to achieve the pressure test effect.

[0014] Specifically, there is a bracket at a position on one side of the test bench far from the test frame, and the driving end of the electric push rod is connected to the positioning frame.

[0015] By adopting the above technical solution, the hydraulic cylinder is supported and fixed by the test frame, and the electric push rod is supported and fixed by the bracket.

[0016] Specifically, an anti-slip pad is adhered to the inner bottom of the positioning frame, and the anti-slip pad is made of rubber material.

[0017] By adopting the above technical solution, the anti-slip pad at the inner bottom of the positioning frame is made of rubber material to increase the friction with the seal, thereby ensuring the positioning stability.

[0018] The beneficial effects of the present utility model:

[0019] (1) For a mechanical seal pressure test device of the present utility model, the electric push rod is supported and fixed by a bracket. When positioning the seal, the positioning frame can be driven by the electric push rod to slide out from the bottom of the test frame under the cooperation of the slide rail, and slide out of the non-pressurizing area, so as to facilitate the operator to place the seal into the positioning frame and perform the positioning operation on the seal in a safe area, thereby greatly improving the safety.
