1. Select tube ◆ as peristaltic pump hose conditions · Has a certain flexibility, that is, the radial compression of the hose can quickly restore shape Has a certain degree of wear resistance · Have a certain ability to withstand pressure No leakage (good air tightness) * Low adsorption, good temperature resistance, not easy to aging, no swelling, corrosion resistance, low precipitate ◆ hose parameters Hose specifications to the diameter, wall thickness as the main parameters, different manufacturers have different ways of expression; Such as: with the specification code and said "diameter × diameter" said. ◆ hose material Silicone rubber, rubber, plastic, synthetic materials, different materials show different performance, have different uses. ◆ Select the hose should consider the following factors Chemical resistance / chemical compatibility Hoses should exhibit some good chemical properties when transferring different fluids, which is called chemical compatibility. Such as: low adsorption, good temperature resistance, not easy to aging, no swelling, corrosion resistance, low precipitation Chemical resistance decreases with increasing temperature. Chemicals that have no effect on the tube at room temperature may affect the tube with increasing temperature. Pressure The application of peristaltic pumps is limited by the pressure-bearing properties of the hose. If the system pressure exceeds the ultimate pressure of the hose, the hose will expand, resulting in excessive hose wear or hose rupture. Affect the hose pressure factors: material, diameter and wall thickness ratio. ·temperature Hose to adapt to the operating temperature range is the user to consider the factors. Different materials have different temperature performance. ·size The size of the hose has a direct effect on the flow rate and the excellent pump design takes into account the inner diameter and wall thickness of the hose to match the optimum hose size or tube number range. The inner diameter of the hose determines the flow rate; wall thickness affects the ability of the hose to be compressed and rebound, and also has a significant impact on the life of the hose. · Certification Hoses may have to pass relevant approvals for their intended use. Such as the US Pharmacopoeia standard USP, the European Pharmacopoeia standard EP, the US Food and Drug Administration standard FDA, the USDA standard USDA and the National Health Foundation standard NSF. Hose flexibility / elasticity / life Different hose resistance roller repeated extrusion, the ability of friction different. Different pipe, pipe, pump head, running speed has a different life expectancy. Life expectancy In the pump system is called the flexible life, in specific applications, the pump features are very consistent. Choose long life, thick-walled tube, the choice of large flow pumps, run at lower speeds can get longer hose life. 2. Select the pump head Choice of single, multi-channel transport fluid Is it easy to change the hose? Is it easy to fix the hose Tube gap through the ratchet fine-tuning, to adapt to different wall thickness of the hose Roller selection: 6 wheel structure relative flow slightly larger; 10 wheel structure fluid pulsation amplitude smaller Trigger the structure is smart, open the card is convenient 3. Select the drive Need to control flow? Whether the need for traffic can be allocated How is the traffic? Degree of protection The overall structure is reasonable More Search Keywords: Pumps Electric Reach Forklifts,Electric Reach Forklift,Walkie Reach Truck,Electric Reach Truck Forklift Jiangsu Lundi Forklift Co.,Ltd. , https://www.lundilift.com
