Which kind of hose is ideal for strong corrosive material
The positive and negative pressure refer to the performance of the hose when subjected to pressure in different directions. They each have specific meanings and application scenarios.
Positive pressure of hose
Positive pressure refers to the pressure of the gas or liquid inside the hose being higher than the environment. Simply put, the substance inside the hose tries to expand outward or push the external substance. In this state, the hose needs to have sufficient strength and stability to withstand the outward thrust generated by the internal substance to prevent the hose from breaking or deforming. In practical applications, positive pressure hoses are often used to transport gas or liquid to a specific area. For example, inflating tires, injecting fluids into pipes, etc. In these scenarios, the hose must be able to withstand high-pressure environments and maintain its structural integrity and sealing. Ensure that the fluid can be transmitted smoothly without leakage.
Negative pressure of hose
Negative pressure refers to the pressure of the gas or liquid inside the hose being lower than the pressure of the external environment. In this case, the atmospheric pressure outside the hose will exert an inward compressive force on the hose. Make the hose try to shrink or collapse inward. Therefore, the hose needs to have good flexibility and sealing to resist external pressure and maintain the stability of its internal space. Negative pressure hoses are used in many fields. For example, the suction system of medical equipment, vacuum packaging machinery, etc. In these applications, the hose needs to be able to withstand the negative pressure environment and prevent external air or impurities from entering the hose, ensuring the normal operation of the system and the quality of the product.
