Description
Technical Parameters
Peristaltic pump 500ml min, also known as hose pump or roller pump, is a positive displacement pump that delivers fluid by rotating rollers or cams to compress elastic hoses,Its flow range depends on the design of the pump head, the size of the hose, and the speed of the motor. Its working principle and structural characteristics make peristaltic pumps widely used in specific fields. In daily use, try to replace the hose as much as possible after prolonged use, so as not to easily cause the silicone hose to rupture. Liquid will flow out of the hose into the roller of the pump head, accompanied by corrosive liquid flowing into the roller gap. The pump head should be disassembled and cleaned in a timely manner to prevent it from solidifying in the roller gap after weathering, which may cause the pump head to get stuck. The hose should be replaced in a timely manner or moved frequently according to the specific frequency of pump use during use. If the liquid has strong corrosiveness, please choose an imported hose of the corresponding material to avoid damage to the pump.
Main Features
The hose is the only component that comes into contact with the fluid, and replacing the hose can be applied to different media, avoiding cross contamination.
This feature makes peristaltic pumps particularly suitable for applications that require high purity and pollution-free requirements, such as pharmaceuticals, biotechnology, and the food industry.
By controlling the roller speed or stepper motor to precisely control the flow rate, it is suitable for situations that require precise measurement.
Peristaltic pumps can provide stable flow output and can precisely control flow by adjusting the speed of the rollers or stepper motors, thus meeting the precise measurement requirements in experiments and production.
Due to the almost smooth movement of fluids within the hose, peristaltic pumps are suitable for conveying liquids with high shear sensitivity, such as solutions containing cells.
The low shear characteristics make peristaltic pumps have significant advantages in applications such as cell culture, blood processing, and biological sample delivery.
Peristaltic pumps can transport various fluids, including organic solvents, corrosive liquids, etc.
The design of peristaltic pumps enables them to withstand the erosion of corrosive liquids, thereby extending the service life and reliability of the pump.
Peristaltic pump 500ml min can operate for long periods of time without water, and can also transport air, gas liquid solid three-phase mixed transportation.
Allow the solid diameter contained in the fluid to reach 40% of the inner diameter of the tubular element, suitable for transporting media such as suspensions and pastes containing solid particles.
Without valves and seals, the pipe is the only component in contact with the medium and can be easily replaced after each process cycle.
The maintenance of peristaltic pumps is relatively simple, only requiring regular replacement of hoses and cleaning of pump heads.
Parameter
Working Principle
Peristaltic pump 500ml min, as a unique fluid delivery device, works based on the peristaltic motion of hoses (or pipelines), achieving precise and pollution-free liquid delivery.
Basic components of peristaltic pump
The peristaltic pump is mainly composed of the following key components:
(1) Motor:
As a power source, it drives the roller or rotor to rotate.
(2) Roller (or rotor):
Responsible for squeezing the hose, forming a closed chamber, and pushing the fluid forward.
(3) Hose:
As a channel for fluid transportation, it is usually made of wear-resistant and corrosion-resistant materials such as rubber, silicone, polyurethane, etc. One end of the hose is connected to the feeding port, and the other end is connected to the discharging port.
(4) Pump casing:
Used to support rollers (or rotors) and hoses to ensure their normal operation.
Working principle of peristaltic pump
The working principle of a peristaltic pump can be summarized as follows:
Roller squeezing hose:
When the peristaltic pump starts working, the motor drives the roller or rotor to roll along the length direction of the hose.
During the rolling process, the roller will squeeze the hose, causing the cross-section of the hose to become smaller and closed, forming a closed chamber.
Liquid transportation:
The peristaltic wave will start moving from the inlet towards the outlet.
As the peristaltic wave advances, the liquid in the enclosed chamber will be pushed to the discharge port.
Whenever the squeezing part passes through the feeding port, new liquid will be drawn into the hose and continue to be transported with the advancement of peristaltic waves.
Formation of peristaltic waves:
When the roller squeezes the hose, the liquid inside the hose will be subjected to squeezing force, thereby forming peristaltic waves inside the hose.
Peristaltic waves are waves composed of continuous contraction and relaxation areas, similar to the movement of worms.
Recovery of deformation of hose:
When the roller no longer squeezes the hose, due to the elasticity of the hose, the squeezed part will return to deformation.
During the recovery process, negative pressure will form near the area, attracting upstream liquid or gas into the hose.
Circular transportation:
As the roller continues to roll, the above process will be repeated continuously to achieve continuous liquid or gas transport.
Principle characteristics
No pollution:
Due to the fact that only the hose comes into contact with the fluid, peristaltic pumps can achieve precise liquid control without pollution or leakage.
01
Wide applicability:
Peristaltic pumps are suitable for transporting high viscosity, corrosive, or volatile liquids.
At the same time, it has less stirring and shearing effect on the liquid, which can maintain the integrity of the liquid.
02
Precise control:
By adjusting the speed of the roller, the diameter of the hose, or the stroke of the pump, the flow rate of the peristaltic pump can be precisely controlled.
03
Self suction ability:
Peristaltic pumps have a certain self-priming ability and can transport fluids containing bubbles and particles.
04
Easy maintenance:
The structure of peristaltic pumps is relatively simple and easy to maintain. Just replace the hose regularly and check the wear of the rollers.
05
Major Component
The main components of a peristaltic pump include the drive mechanism, roller assembly, hose/tubing, pump head/casing, inlet/outlet fittings, and control system.
1. Drive mechanism:
Provide power sources, commonly including electric motors, pneumatic motors, or manual crankshafts.
The driving mechanism is responsible for driving the rotation of the roller assembly, thereby achieving compression and release of the hose.
2. Roller component:
This is the core component of a peristaltic pump, typically composed of two or more rollers (sometimes camshafts) that alternately squeeze the hose.
The rotation of the roller creates a closed fluid chamber inside the hose, pushing the liquid forward.
3. Flexible hoses/pipelines:
The peristaltic pump uses a specially designed elastic hose as a fluid channel.
The material of the hose depends on the properties of the liquid being transported, such as chemical compatibility and temperature range. It is a consumable and needs to be replaced regularly.
4. Pump head/pump casing:
Fix the roller assembly and hose to provide support for the hose and keep it in the correct position.
The pump head design ensures that the hose is uniformly and appropriately compressed, while also facilitating the installation and replacement of the hose.
5. Import/Export Connections:
Connect the two ends of the hose, corresponding to the inlet and outlet of the liquid respectively, to ensure smooth flow of liquid in and out.
6. Control system:
In an electric peristaltic pump, the control system is responsible for adjusting the motor speed, monitoring the working status of the pump (such as flow rate and speed), and may include a digital display interface that allows users to set and adjust pump parameters.
7. Pressure regulating device (optional):
Some peristaltic pumps are equipped with pressure sensors and corresponding adjustment mechanisms to monitor and control output pressure, in order to protect the pump and pipelines from damage caused by excessive pressure.
