The service life of solenoid valve for vibration plate is an important indicator to measure its performance stability. This indicator is not determined by a single factor, but is affected by the comprehensive influence of material properties, working environment, usage, maintenance and other conditions. In actual applications, the life of solenoid valve for vibration plate under different working conditions varies significantly. Only by fully understanding the mechanism of each influencing factor can we take measures from the design, installation, use and other links to extend its effective working cycle and avoid premature failure affecting the operation of the equipment.
Material selection and application are the basic factors that determine the service life of solenoid valve for vibration plate. The material properties of the core components of the solenoid valve, such as the valve body, valve core, and seal, are directly related to its wear resistance, corrosion resistance and fatigue resistance. For example, if the valve body material is not strong enough, it is easy to crack under long-term vibration or medium pressure; if the seal is made of rubber material that is not resistant to medium corrosion, it may fail to seal due to aging and swelling; if the valve core is made of metal material with poor wear resistance, the surface will wear quickly during frequent actions, thereby affecting the opening and closing accuracy. Therefore, high-quality solenoid valve for vibration plate usually chooses suitable materials according to the use scenario, such as stainless steel valve body, carbide valve core, fluororubber seal, etc., to improve the durability of the components.
The adaptability of the working environment plays a key role in the life of the solenoid valve for vibration plate. The environment in which the vibration plate is located is often accompanied by continuous mechanical vibration, which will cause the internal parts of the solenoid valve to resonate. If anti-seismic measures are not considered during the design, loose parts such as bolts and terminals may fall off due to vibration, and the internal coil may also break due to repeated force. In addition, too high ambient temperature will accelerate the aging of the coil insulation layer, and too low ambient temperature may cause the medium to solidify and affect the action; if dust and water vapor in the air enter the valve body, it will cause the valve core to jam or parts to rust; if the medium contains particulate impurities, it will aggravate the erosion and wear of the sealing surface when flowing through the valve port. If these environmental factors exceed the tolerance range of the solenoid valve, its service life will be significantly shortened.
The frequency of use and load state are the direct factors affecting the life of the solenoid valve for vibration plate. If the operating frequency of the solenoid valve exceeds its design rating, the friction between the valve core and the sealing surface will increase, the wear rate will accelerate, and the coil will also overheat due to frequent power on and off. For example, under high-frequency vibration conditions, if the solenoid valve is continuously in a fast opening and closing state, the elasticity of the seal will decay due to repeated compression, and the guide part of the valve stem will also produce a gap due to friction, resulting in malfunction. In addition, if the solenoid valve works for a long time under conditions exceeding the rated pressure or flow, the load on the components will increase, and the accumulation rate of fatigue damage will accelerate, which will also shorten the service life.
The standardization of installation and commissioning is the prerequisite for ensuring the normal operation of the solenoid valve for vibration plate. If impurities such as welding slag and rust remain in the pipeline during installation, the surface of the valve core will be scratched during operation; if the flange connection is not aligned, uneven tightening of the bolts will cause the valve body to deform; wiring errors may cause the coil to burn; if the pressure is set too high during commissioning, the seal will be subjected to stress beyond the design range. Omissions in these installation links will cause failures shortly after the solenoid valve is put into use, even if the solenoid valve itself is of excellent quality, and affect its life. Correct installation should ensure that the pipeline is clean, the connection is firm, the wiring is correct, and the pressure test and action debugging are carried out according to the regulations to keep the solenoid valve in a reasonable working state.
The timeliness and effectiveness of maintenance are crucial to prolonging the life. In daily use, regularly clean the dust and oil on the outside of the solenoid valve and check the tightness of each component to prevent loosening caused by vibration; adding an appropriate amount of lubricant to the moving parts can reduce friction and wear; regularly test the insulation resistance of the coil and replace aging seals to eliminate potential faults in advance. If maintenance is not in place, minor hidden dangers will gradually expand. For example, if a slight scratch on the sealing surface is not handled in time, it may develop into a penetrating leak under the scouring of the medium; dust accumulation on the surface of the coil affects heat dissipation and accelerates the aging of the insulation layer. It can be seen that a scientific maintenance plan can effectively slow down the deterioration rate of components.
The manufacturing process and quality control level are the decisive factors for the intrinsic life of the solenoid valve. High-quality manufacturing technology is reflected in precise processing accuracy, uniform heat treatment, reliable surface treatment and other aspects. For example, if the machining roughness of the matching surface between the valve core and the valve seat is high, the friction resistance and leakage will increase; if the winding process of the coil is not good, it will cause local overheating; if there are pores or incomplete welding in the welding part, cracks are easy to occur under the action of vibration. Strict quality control processes, such as material inspection at the factory, key process monitoring, and finished product performance testing, can ensure that each solenoid valve has stable performance when it leaves the factory. Products that lack strict quality control may have hidden defects and fail prematurely during use.
In addition, the operator's usage habits and troubleshooting capabilities will also indirectly affect the life of the solenoid valve. Standard operation can avoid component damage caused by misoperation, such as frequent start and stop or overpressure operation; timely detection of abnormal phenomena and taking measures can prevent the expansion of faults. For example, when the solenoid valve makes abnormal sounds or heats up, if the operator can quickly stop the machine for inspection, serious problems such as coil burning or valve core jamming can be avoided. On the contrary, if the abnormal situation is ignored and the operation continues with the disease, the remaining life of the solenoid valve will be greatly shortened.
In short, the service life of solenoid valve for vibration plate is the result of the combined effect of many factors such as materials, design, manufacturing, installation, use and maintenance. To extend its service life, it is necessary to control the quality of materials and processes from the source, optimize environmental conditions during use, standardize operating procedures, and establish a complete maintenance system to keep the solenoid valve in an ideal working state, thereby maximizing its service life.
