Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pump pressure resistance detection equipment, in particular to a vacuum pump housing pressure resistance performance detection device. Background Art

[0002] The vacuum pump is a rotary variable volume pump. It must be used with a fore pump. It has a large pumping speed within a wide pressure range and is insensitive to dust and water vapor in the gas being pumped. It is widely used in metallurgy, chemical industry, food, electronic coating and other industries. Vacuum pumps include water ring pumps, reciprocating pumps, sliding valve pumps, rotary vane pumps, Roots pumps and diffusion pumps. At present, these pumps are the main pumps that are indispensable in the vacuum process of various industries in my country's national economy. In recent years, with the continuous and rapid development of my country's economy, the downstream application industries related to vacuum pumps have maintained a rapid growth momentum. At the same time, driven by the continuous expansion of the application field of vacuum pumps and other factors, my country's vacuum pump industry has achieved sustained and stable development.

[0003] The existing referenceable Chinese utility model patent with announcement number: CN213148595U discloses a vacuum pump housing pressure resistance detection device, including: a base, two support columns are fixedly arranged on both sides above the base, and a support cross plate is fixedly arranged on the top of the support column; a downward pressing structure, the downward pressing structure is located above the support cross plate, the downward pressing structure includes a hydraulic cylinder, a fixed plate, a support block, a downward pressing plate and a pressure sensor, and a hydraulic cylinder is fixedly arranged on the top of the support cross plate. The utility model can drive the fixed plate to move through the hydraulic cylinder, and can make the downward pressing plate squeeze the vacuum pump housing. Since the force is opposite, the magnitude of the force can be detected by the pressure sensor, and the fixed plate and the support column are slidably connected, which can prevent the fixed plate from deflecting during the downward pressing process.

[0029] A measuring rod 22 is fixedly mounted on the top of the damping telescopic rod 21 , and a pointer 23 is fixedly mounted on the bottom of one side of the measuring rod 22 .

[0030] Specifically, by fixing the rotation of the rotating shaft 2, the measuring rod 22 can be rotated, and by the damping telescopic rod 21 having damped telescopic properties, the measuring rod 22 can be adjusted to a height that fits the top of the vacuum pump housing. The pointer 23 on the other side of the measuring rod 22 can correspond to the measuring ruler 16 to measure the height of the vacuum pump housing, so that whether the vacuum pump housing is deformed can be detected after the pressure resistance test.
