The service life of diaphragm pumping vacuum pumps is affected by the following factors:
Material quality:
Diaphragm material: Diaphragm is a key component, and materials with good wear resistance, corrosion resistance, and flexibility, such as fluororubber, should be selected. If the material quality is poor, it is prone to cracking or damage during long-term reciprocating motion.
Pump body material: High quality pump body material can withstand high pressure and temperature, is not easy to deform or leak, and ensures the structural stability and sealing of the pump.
Manufacturing process: Advanced production technology can ensure the precision of component processing and assembly quality, making the operation of vacuum pumps more stable and reliable. High precision machining can ensure the fitting accuracy between components, reduce wear and leakage; A good assembly process can avoid the problem of uneven stress on components caused by improper assembly.
Application environment:
Gas chemical composition: If the extracted gas contains corrosive or active components, it will accelerate the corrosion and degradation of pump components such as diaphragms and pump bodies, shorten their service life, unless the pump is chemically compatible with the extracted gas.
Temperature and humidity: High temperature environments can cause a decrease in the performance of pump components, accelerate aging, and may also lead to the deterioration of lubricating grease; High humidity environments may cause corrosion or condensation issues, affecting the normal operation of the pump.
Pollutants: Dust, particles, and other pollutants from the working environment entering the pump can exacerbate component wear and affect sealing performance.
Operating conditions:
Vacuum degree and flow rate: Long term operation at maximum capacity or extreme vacuum levels will cause the pump components to withstand greater pressure and wear, such as frequent stretching and compression of the diaphragm, and long-term high load operation of the motor, thereby shortening the service life.
Frequency of use: Frequent starting and stopping of the pump can cause significant impact stress on the components, such as high starting current of the motor, which can easily damage the motor winding; Diaphragm can also accelerate fatigue due to frequent movements.
Power stability: Unstable power supply, such as voltage fluctuations, current overload, etc., can cause motor overheating and damage, affecting the overall performance and lifespan of the pump.
Maintenance and upkeep:
Regular maintenance: including routine inspection, cleaning, oil change (for parts that require lubrication), replacement of filters and worn parts, etc. Neglecting maintenance can lead to increased component wear, internal contamination, and ultimately cause malfunctions.
Maintaining Quality: Proper procedures and qualified replacement parts must be used during the maintenance process. Incorrect maintenance methods or the use of inferior parts may not solve the problem and may even trigger new malfunctions.
Installation situation:
Installation location: The pump should be installed in a clean, dry, and well ventilated environment, avoiding installation in places with corrosive gases, high temperatures, high humidity, or high dust.
Correct installation: During installation, it is necessary to ensure that the pump body is level, the connection is firm, the pipeline connection is correct, and to avoid the transmission of pipeline stress to the pump, which may affect the normal operation and component life of the pump.
