Development History Of Industrial Hose

Oct 07, 2020

Development process of hose pump the hose pump has been used in the industrial field for many years, and the earliest original design can even be traced back to more than half a century ago. The hose pump belongs to the category of Peristaltic pump. Industrial Hose
Peristaltic pump is a kind of rotor-type displacement pump, because its working principle is similar to the digestive tract to transport gas, solid, liquid three-phase media and named. There is no strict distinction between the hose pump and the peristaltic pump. In general, peristaltic pumps refer to small flows (in ml/sub), Low outlet pressure (not exceeding 3kg/cm2), and are used in the health field and laboratory metrology. and the hose pump refers to the large flow (up to 80 Limi/h), high output pressure (up to 16kg/cm2), mostly used in industrial occasions for large-flow transport and metering. This paper discusses the industrial hose pump.Industrial Hose
The designer and user of hose pump is the ability of conveying strong abrasive medium. It has no valve, no seal, the only part contacting with the medium is the inner cavity of the rubber hose, and the rotor of the compression hose is completely independent of the medium. In addition, hose pump has a lot of originality: no other pump than hose pump has better self-priming ability, can produce the perfect vacuum to absorb liquid, the transportation contains the gas liquid, the froth liquid without the air resistance, transports the high viscosity, the shearing sensitive medium is also the strength; each fixed displacement is independent of the outlet pressure and is a natural metering pump.Industrial Hose
A high-quality hose pump life in 7-10 years, the biggest challenge lies in hose pump hose, it is the core of the hose pump, its life directly related to the use of pump costs. It can be said that the hose pump is designed around the hose to maximize life. The abrasive medium does have the wear to the hose inner wall, so that the known hose wall thickness becomes thinner, resulting in the internal leakage or backflow and flow drop due to the compaction of the tube; The inner leakage further increases the wear speed of the inner wall.Industrial Hose
