Detailed Description
Example (b):
as shown in fig. 1-4, a bellows mechanical seal pressure testing device, including support 1, high-order oil tank 2, oil groove 3, scale 4 and splendid attire mechanical seal ring's pressure testing case, 2 fixed mounting in 1 top of support of high-order oil tank, the pressure testing case passes through backup pad 8 to be fixed at 1 intermediate position of support, 3 fixed mounting in 1 bottom of oil groove, the pressure testing case includes base 5 and upper cover 6, connect through bolt 7 between base 5 and the upper cover 6, the pressure testing case periphery is located to scale 4, 4 lower extremes of scale pass through branch 9 to be fixed in the base 5 outside, 6 lower extremes of upper cover are equipped with the pointer 10 of directional scale reading.
The base 5 and the 6 center in upper cover are equipped with inlet port 51 and oil outlet 61 respectively, the oil-out of high-order oil tank 2 passes through inlet tube 11 and connects inlet port 51, inlet tube 11 passes backup pad 8 and connects inlet port 51, oil outlet 61 connects out oil pipe 12, be equipped with three branches on the oil pipe 12, air pump 13 is connected in first branch, and hydraulic pump 14 is connected in the second branch, the preferred manual plunger type hydraulic pump of hydraulic pump 14, manometer 15 is connected in the third branch, be equipped with blow off pipe branch 16 on the inlet tube 11, blow off pipe branch 16 accesss to oil groove 3. And the oil inlet pipe 11, the first branch of the oil outlet pipe 12, the second branch of the oil outlet pipe 12 and the sewage discharge pipe branch 16 are all provided with switch valves.
When the mechanical seal device is used specifically, a mechanical seal is placed in a pressure testing box, the mechanical seal comprises a mechanical seal movable ring and a mechanical seal static ring, the mechanical seal static ring is arranged under the mechanical seal movable ring, so that an oil inlet hole 51 and an oil outlet hole 61 are communicated with a mechanical seal central hole, a bolt 7 is screwed, the reading of a scale pointed by a pointer 10 is adjusted, the compression amount of the mechanical seal is adjusted to achieve the working state of the mechanical seal, at the moment, a sealed cavity is formed between the mechanical seal and the pressure testing box, then, a valve of a high-level oil tank 2 is opened, hydraulic oil enters the sealed cavity through an oil inlet pipe 11, the valve of the high-level oil tank 2 is closed, a hydraulic pump 14 is operated to enable the pressure in the sealed cavity to rise to standard data, if the data of a pressure gauge 15 does not change, the sealing performance is good, at the moment, the valve of the high-level oil, the hydraulic oil is pushed back to the high-level oil tank 2 through the compressed air, then the valve of the high-level oil tank 2 is closed, the valve of the blow-off pipe branch is opened, the residual hydraulic oil is completely discharged, and the pressure test is completed.
