Peristaltic pump pulse suppressor
What is the peristaltic pump?
pumps act like squeezing a fluid-filled hose with your finger and
moving forward as your finger slides the fluid in the tube forward.
Peristaltic pumps are based on the same principle, but use rollers
instead of fingers. The fluid is pumped by alternately squeezing and
releasing the pump's flexible delivery hose. Just like squeezing a hose
with two fingers, as the fingers move, negative pressure builds up in
the tube and the liquid flows with it. The peristaltic pump is a part of
the pump tube between two rollers that forms a "pillow" shaped fluid.
The volume of the "pillow" depends on the inner diameter of the pump
tube and the geometry of the rotor. The flow rate depends on the product
of three parameters: the speed of the pump head, the size of the
"pillow", and the number of "pillows" produced by the rotor per
revolution. The size of the "pillow" is usually constant (except when a
particularly viscous fluid is pumped). A pump with a larger "pillow"
volume will transport a larger volume of fluid per revolution of the
rotor than a pump with the same rotor diameter, but with a greater
degree of pulsation. This is similar to the case of diaphragm valves.
For pumps that produce smaller "pillow" volumes, the amount of fluid
transported by the rotor per revolution is also smaller; Moreover, small
"pillows" formed in rapid succession make fluid flow more stable. This
is similar to the way gear pumps work.
Advantages and disadvantages of peristaltic pump
1. No pollution: fluid only contact with the pump tube, not the pump body;
2. High precision: good repeatability, high stability, and high precision;
3. Low shear force: ideal tool for conveying shear sensitive and corrosive fluids;
4, good air tightness: strong self-priming ability, idling, prevent backflow;
5. Simple maintenance: no valves and seals;
Two-way equal flow transmission capacity; In the absence of liquid and
dry operation, will not damage any parts of the pump; It can produce up
to 98 percent vacuum; There are no valves, mechanical seals, and packing
seals, so there are no leakage and maintenance factors; It can easily
transport solid, liquid or gas-liquid mixed phase fluid so that the
solid diameter contained in the fluid reaches 40% of the inner diameter
of the tube element; It can transport a variety of abrasive, corrosive
and oxygen-sensitive materials and a variety of food, etc. Only the hose
needs to be replaced, and the operation is very simple. The product
transported does not touch any components except hoses.
1. Pressure limitation: the use of flexible tubing will limit the pressure
2. Pulse flow is generated when the pump is running
The solution: use a pulse suppressor
pulse suppressor is a simple locator container. It works because air
compresses more easily than liquid. The pulse stream enters the
container, the airbag on the liquid sinks to absorb the pulse, and then
smoothly flows out of the pulse suppressor.
Peristaltic pump by adjusting the speed and changing the pump tube
diameter to achieve flow change. The peristaltic pump flow range is
is the peristaltic pump? The working principle and advantages and
disadvantages of the peristaltic pump are introduced to everyone.
Peristaltic pumps are ideal for laboratory, pilot plant, and process
applications, as well as distribution, metering, and general delivery
applications. Peristaltic pumps also have a soft pumping effect and are
ideal for shear-sensitive polymers and fragile cell cultures.
