Parameters
The effect of pressure on the hose
Hose pressure and wear
Pressure and hose life:
The pressure of the best peristaltic pump is determined by the pressure pipe gap, the tighter the pressure pipe, the greater the pressure, the greater the wear on the hose, and the hose life will be shortened. On the contrary, the looser the pressure pipe, the longer the hose life will be.
The pressure bearing capacity of the hose is limited, and once the system pressure exceeds the limit pressure of the hose, the hose may expand, excessive wear or even rupture, thus affecting the normal operation of the system.
Effects of material and wall thickness:
The material and wall thickness of the hose have an important effect on its bearing capacity. Different materials of hoses have different physical characteristics and chemical stability, so the pressure capacity will be different.
Increasing the wall thickness can improve the bearing capacity of the hose, but it will also increase the rigidity of the hose and reduce its flexibility.
Hose performance changes
Elasticity and tightness:
Working under high pressure for a long time may cause the elasticity of the hose to decline and the sealing performance to deteriorate, thus affecting the pumping efficiency of the peristaltic pump and the stability of the fluid transport.
Chemical compatibility:
The chemical compatibility of the hose refers to the ability of no chemical reaction or physical change between the hose and the fluid being transported. High pressure can cause the hose material to deform or age, which in turn affects its chemical compatibility with the fluid.
Hose selection and replacement
Select the right hose:
In the selection of peristaltic pump supporting hose, should fully consider the nature of the conveyed fluid, working pressure, temperature range and other factors to ensure that the hose pressure capacity and chemical compatibility meet the requirements.
Replace hose regularly:
In order to ensure the stability and safety of the peristaltic pump system, the hose should be checked regularly and replaced in time when signs of wear or aging are found. Especially under high load working conditions, the replacement cycle of the hose should be shortened.
The ability of a hose to withstand pressure
The ability of the hose to withstand pressure depends on many factors such as its material, specifications, design and use environment. The following is a detailed analysis of the hose's ability to withstand pressure:
Hose material and bearing capacity
Rubber hose
It is usually used in high pressure environments because of its good elasticity and pressure resistance.
The pressure range varies according to the specific material and specifications, but is generally higher.
PVC hose
Lightweight, durable and low cost, it is widely used in low pressure water transmission systems.
The bearing capacity is relatively low, suitable for low pressure environment.
Metal hose
For example, DN100 metal hose is usually composed of three parts: bellows, mesh sleeves and joints.
The bellows are the core, responsible for the actual flexible fluid transport; The mesh sleeve is used to increase the mechanical strength and pressure resistance of the hose.
The pressure bearing capacity can usually reach 1.6MPa to 6.4MPa, depending on the material and ripple design.
Hose specifications and bearing capacity
Inner diameter, outer diameter and wall thickness
The inner diameter, outer diameter and wall thickness of a hose are important factors affecting its bearing capacity.
Hoses with thicker walls can withstand higher pressures.
Length and connection
The length and connection of the hose will also affect its bearing capacity.
The proper connection ensures that the hose will not leak or fall off under high pressure.
The impact of the use environment on the pressure bearing capacity of the hose
Temperature
Under extreme high or low temperature conditions, the coefficient of thermal expansion of the material will change, which will affect the overall pressure performance of the hose.
Under high temperature environment, the strength of the metal hose may decrease.
Medium properties
Different fluid media have great differences in the corrosiveness and erosion of hoses.
Choosing the right hose material to improve corrosion resistance is crucial.
Fatigue use
Under frequent pressure fluctuations and vibration conditions, the service life and bearing capacity of the hose will be affected.
Long-term fatigue may lead to the formation of micro-cracks in the hose, which will affect its structural stability and bearing capacity.
Reference range of hose bearing capacity
Ordinary hose:
The pressure range is wide, usually between 10 and 50 kg (about 1MPa to 5MPa), but the specific value will vary according to the difference in material and specifications.
Household hose:
It can withstand pressure from 1.6MPa to 2.5MPa.
Industrial high pressure hose:
The pressure range is between 10MPa and 70MPa.
Special high pressure applications:
Special high-pressure hoses should be selected, and their pressure capacity can be far greater than that of ordinary hoses, reaching or even exceeding 1000 kg (about 10MPa).
Precautions
Safe use:
Ensure that the hose application environment matches its design specifications and avoids extreme temperature and humidity conditions.
Regular inspection and timely replacement of hose is the key to prevent aging and damage.
Avoid excessive bending:
When using, attention should be paid to avoid excessive bending and deformation problems when hanging and fixing, so as to ensure smooth and safe fluid transmission.
In summary, the ability of the hose to withstand pressure is a complex parameter, which is affected by many factors. When selecting and using hoses, it is important to refer to the technical specifications and product test reports provided by the manufacturer to ensure that the hose is working within a safe pressure range.
How to avoid clogging
Select the right pump type and fitting
Pump type selection
Select the best peristaltic pump model based on the properties of the fluid being transported (such as viscosity, particle size, corrosion, etc.).
For fluids containing larger particles or high concentrations of suspended matter, a pump type with larger conveying capacity and higher pressure should be selected.
Pipe material
Select corrosion-resistant and wear-resistant pipe fitting materials, such as silicone, fluororubbers, etc., to adapt to the chemical properties of different fluids.
Ensure that the inner wall of the pipe is smooth, reducing the friction resistance and the possibility of fluid accumulation in the pipe.
Adjust the operating parameters of the pump
Speed adjustment
Appropriately increasing the pump speed can improve the dispersion of particles in the liquid, reduce the agglomeration of particles, and thus reduce the risk of blockage of particles to the pump.
However, it should be noted that too high speed may aggravate the wear and energy consumption of pipe fittings.
Pressure control
By adjusting the pressure of the pump, the degree of particle extrusion in the pump can be controlled, further reducing the risk of clogging the pump.
Ensure that the working pressure of the pump is within the pressure range of the pipe fitting and the pump head to avoid excessive extrusion leading to pipe cracking or deformation.
Install the filter and cleaning device
Filter device
Install a filter or filter at the entrance of the pump to filter particles and impurities in the liquid to prevent them from entering the pump and causing blockage.
Check and clean the filter or filter regularly to ensure that it is unimpeded.
Cleaning device
Equipped with a cleaning device for regular cleaning of particles and impurities that accumulate in the pump.
The cleaning device can clean the accumulation in the pump by periodically spraying the cleaning liquid or gas, and drain it out of the pump.
Regular inspection and maintenance
Check pipe fittings
Regularly check the wear of the pipe fittings (such as hoses) of the peristaltic pump, and timely replace the pipe fittings with serious wear.
Ensure that pipe fittings are securely connected to avoid leakage and clogging.
Maintenance pump head
Regular inspection and replacement of pump heads and rollers and other wearing parts to ensure their normal operation during use.
Clean up the accumulation and impurities in the pump head, keep the pump head clean and unblocked.
Pay attention to operation details
Correct installation
Make sure the peristaltic pump is installed correctly and the hose connection is tight and reliable.
Avoid distortion and discounting of the hose during installation, which will affect the smooth flow of the fluid.
Operation specification
Wear personal protective equipment such as gloves, glasses, and protective clothing during operation.
Avoid arbitrarily adjusting parameters such as speed and pressure during pump operation, so as not to cause damage to the pump or increase the risk of blockage.
