Do you know what PVC suction hose is?

PVC suction hose is a tubular elastic sensor made of plastic foldable wrinkle sheets connected along the direction of folding and expansion. Bellows are widely used in instruments and instruments. They are mainly used as measuring elements of pressure measuring instruments to convert pressure into displacement or force. The bellows have thin wall and high sensitivity, ranging from tens of MPa to tens of MPa. The opening end is fixed, the sealing end is in a free state, and the auxiliary coil spring or spring is used to increase the elasticity. When working under the action of internal pressure, it extends along the length direction of the pipe, resulting in displacement of the movable end which has a certain relationship with the pressure. The active end can directly indicate the pressure by driving the pointer. Bellows are often combined with displacement sensors to form pressure sensors that output electricity, sometimes used as isolation elements. The response speed of bellows is lower than that of Boden tubes because the expansion of bellows requires a larger volume change. Bellows are suitable for measuring low pressure.
PVC suction hose (PA, PE, PP) is widely used in machine tool machinery and cabinet control cabinet wiring connection, and has a plastic fast joint supporting. The product specifications include AD7.0, AD10.0, AD13.0, AD15.8, AD21.2, AD25.0, AD28.5, AD34.5, AD42.5, AD54.5, black and grey color, etc. The product is beautiful, portable and durable. It is widely used in automotive wiring harness, electronics, mechanical wiring harness and other fields, replacing the original PVC and metal sheath products, and becoming wildly used wiring harness sheath products in the market.
