NYP high viscosity heat pump medium viscosity standard
NYP high viscosity heat pump applicable medium temperature: -10 ℃ - 150 ℃; high viscosity pump applicable medium viscosity: 1.0cst - 300000cst
Application of high viscosity pump:
NYP high viscosity heat pump used in petroleum, chemical, paint, oil, medicine, dyes, food industry etc.. Applications include transport of organic acid, fatty acid, alkaline substances, caustic soda, soda water, polymer, soap, shampoo, animal fat, vegetable oil, chocolate and other special fluid.
Viscosity is the lubricating fluid friction resistance. The viscosity of the medium is an important technical parameter of high viscosity pump, is closely related to the performance and high viscosity pump. There are many kinds of viscosity units, were as follows.
(1) dynamic viscosity (absolute viscosity)
In the international system of units, such as the distance 1m, area of each to produce speed is relatively mobile 1m/s 1m2 two layer parallel between fluids, the applied force is 1N. The dynamic viscosity is 1Pa · s (Pa). 1Pa s=1N s /m2, commonly used for mPa. The CGS system unit dynamic viscosity is P (Bo), often think of the P unit is too large and often use cP (CPS). The relationship between it and the international system of units units are: 1cP=0.001Pa, S.
(2) the kinematic viscosity
The measurement is not usually viscometer viscosity μ, but u / P, P is the density of the fluid, the unit kg/m2 or g/cm2. This ratio is called the kinematic viscosity V, i.e. v = u / P. Kinematic viscosity is m2/s in the international system of units, the CGS system is (St), 1St=1cm2/s, but the actual is commonly used centistoke (cSt), 1 cSt=1mm2/s, 1St=100cSt
Condition (3) viscosity
In addition to u and V, in practice often encounter various conditions such as viscosity, Engler viscosity (oE), Saybolt Viscosity (SUS, Saybolt seconds (RSS) and redwood, Redwood seconds). Viscosity of common conditions in China have Engler viscosity and Saybolt viscosity.
The efficiency and speed of viscosity parameters related to the high viscosity pump, gear pump, heat pump, screw pump, arc gear pump conveying fluid pump products, so we should combine the actual need to select the appropriate viscosity parameters.
