Summary
The classification of peristaltic pump oil is mainly based on composition and performance, and the user should choose the appropriate lubricating oil according to the specific working conditions and equipment requirements to ensure the efficient and stable operation of the equipment.
Common replacement cycle recommendations
For the newly purchased peristaltic pump, it is recommended to replace the pump oil every 100 hours after one month of use. This helps ensure smooth operation of the pump during the initial phase and reduces contamination of the pump oil due to impurities generated during the run-in period.
After the peristaltic pump enters the normal working stage, the pump oil can be replaced every 500 hours. This cycle is determined according to the oxidation, contamination and loss of the pump oil during use.
If the peristaltic pump works in a high temperature, humid, dusty or corrosive environment, the replacement cycle of the pump oil may need to be shortened. Because these environmental factors will accelerate the oxidation and pollution of the pump oil, thus affecting its lubrication and sealing performance.
If the peristaltic pump is used very frequently, such as running more than 8 hours per day, then the replacement cycle of the pump oil may also need to be shortened accordingly. Because the high frequency of use will accelerate the loss of pump oil and pollution.
Different brands and types of pump oil have different performance and service life. Therefore, when choosing pump oil, you should refer to the manufacturer's recommendations, and choose the right type and quality of pump oil according to the specific working environment and use conditions of the pump.
In addition, when replacing the pump oil, the following points should also be noted:
Clean the pump body
Before replacing the pump oil, the pump body and related components should be cleaned first to avoid contamination of the new pump oil by impurities and residues.
Check the oil level
When replacing the pump oil, check whether the oil level of the pump body is within the specified range. If the oil level is too low, the pump oil should be replenished in time; If the oil level is too high, excess pump oil should be removed.
Use the right tools
When changing pump oil, use the right tools and containers to avoid pump oil leakage or pollution of the environment.
Record the replacement time
Each time you replace the pump oil, record the replacement time and pump oil type for follow-up and maintenance.
Extreme pressure performance
Definition of extreme pressure properties
Extreme pressure performance refers to the ability of lubricating grease to resist sintering and abrasion on the surface of friction pair under the condition of low speed and high load or high speed impact load. It is an important performance indicator of lubricating oil, especially under the condition of high load pressure, the extreme pressure performance directly affects the operating stability and service life of the equipment.
Test methods
Four-ball method
Principle: The four-ball method is to simulate the contact of the friction pair, apply the load between the four steel balls, observe and record the wear of the surface of the steel balls, so as to assess the extreme pressure performance of the lubricating oil.
Main detection indicators: including the maximum non-bite load PB value, sintering load PD value, comprehensive wear value ZMZ and wear spot diameter D, etc. These indexes can fully reflect the extreme pressure performance of lubricating oil.
Application: The four-ball method is widely used in the extreme pressure performance evaluation of engine oil, gear oil, industrial lubricating oil, etc.
Timken machine test method
Principle: The Timken machine test method is to install the test ring on the fixed spindle, rotate at a certain speed, and apply load to the torus with a grinding block, observe and record the wear mark to assess the extreme pressure performance of the lubricating oil.
Main detection index: The maximum load value without bruising (OK value).
The basis of judgment
PB value
The higher the PB value, the greater the oil film strength of the lubricating oil, the stronger the ability to resist the sintering and abrasion of the friction surface.
PD value
PD value reflects the ultimate working capacity of the lubricating oil. The higher the PD value, the better the EP performance of the lubricating oil under extreme conditions.
ZMZ value
The smaller the ZMZ value, the stronger the oil resistance to extreme pressure to minimize wear under the applied load.
Wear spot diameter D
The smaller the wear spot diameter D, the stronger the anti-wear ability of the lubricating oil, the better the protection effect on the surface of the friction pair.
Precautions
Test conditions
When performing the extreme pressure performance test, the test conditions should be strictly controlled, including temperature, load, speed, etc., to ensure the accuracy of the test results.
01
Equipment calibration
Test equipment requires regular calibration and maintenance to ensure the accuracy of measurement results.
02
Sample preparation
The sample should be thoroughly stirred to avoid contamination during sampling.
03
Data recording and analysis
During the test process, the data should be recorded in detail and analyzed comprehensively to accurately determine the EP performance of the lubricating oil.
04
Dynamic viscosity measurement
The measurement of dynamic viscosity of the oil is the key link to evaluate the flow performance and lubrication effect of the pump. The following are the general steps and methods for measuring its dynamic viscosity:
Measurement principle
Dynamic viscosity describes the ability of a liquid to resist flow when subjected to external forces. The dynamic viscosity of peristaltic pump oil is usually measured using a viscometer, which works on the basis that the flow time of the liquid in the capillary is proportional to its viscosity.
Measurement steps
Prepare instruments and materials
Viscometer: Choose a glass capillary viscometer or an automatic viscometer that meets your measurement requirements.
Thermometer: Used to measure the test temperature to ensure constant temperature.
Stopwatch: Used to record the flow time of liquid in the capillary.
Peristaltic pump oil sample: ensure that the sample is fully stirred evenly, and avoid contamination during the sampling process.
Instrument calibration
Calibrate the viscometer to ensure accurate measurement.
Check the accuracy of the thermometer and stopwatch.
Measurement temperature control
Place the viscometer and thermometer in a thermostatic bath and adjust to the predetermined measurement temperature.
Keep it at a constant temperature for a while to ensure a stable temperature.
Loading sample
Load the oil sample into the viscometer, taking care to avoid bubbles and impurities.
Start measuring
Turn on the viscometer and let the liquid flow through the capillary.
At the same time, the stopwatch is activated to record the time of liquid flow from one end of the capillary to the other end.
Repeated measurements
In order to improve the accuracy of the measurement, it is usually necessary to repeat the measurement several times and calculate the average value.
Calculate the dynamic viscosity
According to the measured flow time and the capillary constant of the viscometer, the dynamic viscosity of the peristaltic pump oil can be calculated. The formula is usually:
Dynamic viscosity = capillary constant × flow time × liquid density
Among them, the liquid density can be measured by other methods at a predetermined measurement temperature.
Precautions
Temperature control
Temperature has a great influence on the dynamic viscosity, so the measurement temperature must be strictly controlled.
Instrument cleaning
Before measuring, ensure that the viscometer and other instruments are clean to avoid the impact of impurities on the measurement results.
Sample handling
The sample should be thoroughly stirred to ensure that it is not contaminated during the sampling process.
Measurement accuracy
In order to improve the accuracy of the measurement, the instrument with higher accuracy should be used and the standard measurement steps should be followed.
Through the above steps and methods, the dynamic viscosity can be accurately measured, which provides an important basis for evaluating its flow performance and lubrication effect.
