[Asia Pump Network News] hose pump is a category of peristaltic pump. Peristaltic pump is a kind of rotor-type positive displacement pump, because of its working principle is similar to the digestive tract feeding peristaltic gas, solid and liquid named after the three-phase medium. Now to introduce the working principle and characteristics of the hose pump is what. Hose pump First, the working principle of the hose pump Hose pump work, the rotor body rotation, the rotor body of a pair of pressure roller along a special hose rotation, the pressure roller and the pressure generated by the pump casing pressure Flat, under the coercive force of the tube itself and the side guide roller, draws the liquid through the vacuum generated by the restoration of the original shape, and the liquid is discharged from the tube under the mechanical squeeze of the pressing roller, thus reciprocatingly circulating. The pump structure is simple, easy to make. Pump durability depends mainly on the flexibility and corrosion resistance of the pipe, the flow and the motor speed and the size of the tube diameter, so the key is to choose the tube and speed control mechanism, as long as the tube has a long enough life, speed stability, long-term There is no problem with maintaining a constant delivery. Second, the characteristics of hose pumps (1) is a positive displacement pump, with or without mechanical seal, self-priming ability, self-cleaning and other characteristics. (2) No pump valve, stuffing box, will not produce the leakage of sealing pump and air resistance phenomenon. (3) simple structure, strong adaptability, liquid, gas, slurry and viscous suspended material can be transported, especially the smooth hose cavity can pump impurities liquid, a variety of fiber objects and containing the particle size of Hose diameter 1/4 below the solid slurry, and does not produce any blockage. (4) without running the pump before running, dry running, there will be no spindle seals and other failures, the pump suction liquid only contact with the hose, it can transport rubber can withstand corrosive and abrasive media, you can replace the general Stainless steel pump. (5) can be positive and negative rotation, without setting the import and export, less power consumption, high hydraulic and volumetric efficiency. (6) It has good metering capacity, can be used as metering pump, can change the flow rate by selecting the size of the pipe and adjusting the speed, wide range of flow (3 ~ 9m3 / h), measurement accuracy, high repeatability. Many materials (vinyl plastic, nylon, rubber and silicone rubber, etc.), suitable for conveying a variety of corrosive, toxic, sterile, radioactive and other media. Tube diameter 0.5 ~ 75mm, the working pressure up to 0.98MPa, working temperature -62 ~ +260 'C tube extrusion contact life is generally 200 ~ 700h. When you can not continue to use, you can change the extrusion of the pipe or replace the new tube. (8) 1 pump head can hold 1 to 20 tubes or 1 pump Install multiple sets of pump head work, while conveying one or more media. A multi-purpose pump, a pump instead of several pumps (suction, row can be homework), small size, high efficiency.

Thermostatic faucets also called thermostatic taps or thermostatic valves. It`s having or maintaining a consistent temperature. You will not feel too cold or too hot when open the faucet (also spigot or tap: see usage variations) for washing and drying.
