The design structure of the bladder type pulsation damper consists of an air tank with an airbag inside, which is filled with gas at a certain pressure. In the pipeline, the liquid compresses the airbag, causing it to contract and then expand, thereby providing a buffering effect. Compared to diaphragm-type dampers, airbag pulsation dampers are characterized by high sensitivity, better elimination of pulse effects, and the ability to withstand higher pressures. Our bladder type pulsation dampers have a maximum pressure rating of 40 MPa.
Our PVC bladder pulsation dampers are generally used in low-pressure applications. PVC has good corrosion resistance to a variety of chemicals, making it suitable for various harsh environments. Compared to metal materials, PVC is lighter, lower in cost, and easier to process and mold, allowing for customization of the airbag's shape and size according to specific requirements. PVC is also highly resistant to water, making it suitable for damp or underwater environments.
In summary, PVC airbag dampers have significant advantages in terms of cost, corrosion resistance, and processability, making them suitable for hydraulic fluid systems,chemical dosing systems etc. in various industries.
A simple selection method is to multiply the pump's stroke volume by 10, which gives the minimum volume needed to reduce 90% of the pulse.
