What is the service life of the peristaltic pump hose? How much do you know?
The commonly used material for peristaltic pump tube is silica gel. The silicone tube has stable chemical properties, high mechanical strength, and good thermal stability. It can be used at high temperature of 200 °C ~ 300 ° C, and does not occur at -60 °C ~-70 °C. brittle. It is not sticky in the air for a long time, does not crack, has good surface activity and does not degrade, so silicone rubber is considered to be the best material for peristaltic pump tube. The principle of the peristaltic pump to deliver liquid is to continuously squeeze the pump tube by the roller connected by the rotor, and continuously use the pressure between the roller and the pump head to continuously deliver the liquid.
The peristaltic pump used for water quality monitoring equipment needs long-term operation in corrosive environment, especially multi-parameter water quality monitoring equipment. The peristaltic pump tube is more corrosive than the corrosive reagent, and the continuous operation time is longer. The silicone tube is subjected to high strength for a long time in a corrosive environment. Extrusion will inevitably affect the self-elastic recovery after extrusion (returning the full cavity of the cavity before extrusion), affecting the uniformity of the inner diameter of the pipe, and thus affecting the conveying precision of the peristaltic pump. Therefore, it is necessary to study the service life of the pump tube to replace it regularly so as not to affect the water quality monitoring results and cause environmental management decision errors.
Since the pump tube is damaged, it mainly affects its self-recovery, which makes the inner diameter change and affects its sampling speed (or flow rate L/h ). Therefore, the flow rate change during the use of the peristaltic pump can be used to monitor whether the pump tube is damaged. .
Through the above introduction, everyone knows it! Baoding Shenchen is a professional manufacturer of peristaltic pumps, applying innovative technology and excellent technology.
Dietary Supplements
The United States Food and Drug Administration (FDA) has published the Dietary Supplement Health and Education Act (DSHEA), which provides for dietary supplements. A product (other than tobacco) intended to supplement the diet may contain one or more of the following dietary ingredients: A vitamin, a mineral, an herb (herbal) or other plant, an amino acid, a food component used to increase the total daily intake to supplement the diet, or a concentrate, metabolite, component, extract or combination of the above ingredients, etc. It also includes approved new drugs, vitamins or biologics that have been marketed as dietary supplements or food products before they are approved, issued or licensed. The DSHEA defines dietary supplements as their composition and labeling requirements: the product form may be pill, capsule, tablet or liquid; The product shall not be used as a substitute for ordinary foods or as an exclusive dietary item. The product shall be labeled as a "dietary supplement".
