Proper use and maintenance of pneumatic components

In a manufacturer of pneumatic component, pneumatic components for maintenance is very important. A pneumatic device, if not pay attention to maintenance work, there will be frequent premature damage or failure, so that the life of the device is greatly reduced when the pneumatic device maintenance, for signs of the accident should be found, to take timely measures, this can reduce and prevent the occurrence of failure, extend the life of components and pallet systems. Therefore, enterprises should develop maintenance management practices pneumatic devices to enhance management education and strict management.
Maintenance work the central task is to ensure the supply of clean and dry compressed air pneumatic system to ensure the tightness of the pneumatic system to ensure the lubrication oil mist lubrication device was necessary to ensure the pneumatic components and systems are specified operating conditions (such as the use of pressure, voltage, etc.) to ensure the pneumatic actuator according to predetermined requirements work.
Lubricator best selection of primary specifications one week up the oil, when up the oil, pay attention to reduce the amount of oil situation. If the fuel amount is too small, readjust the amount of drip, drip volume remained after adjustment to reduce or drop of oil, check the lubricator Importers is installed backwards, if the oil duct blockage, if the specification of the selected oil mist Suitable.
Monthly quarterly maintenance work should be more careful than the daily and weekly maintenance work, but still limited to the outside to check the scope. Its main contents are: Carefully inspect the entire leak case, tighten loose screws and fittings, terminal blocks check valve exhaust air quality, check the flexibility to adjust the portion of the check indicates the correctness of the meter, check valve switching operation reliability, quality inspection of the cylinder piston rod and everything from the outside to check the contents.
Maintenance work can be divided into regular maintenance and periodic maintenance. The former refers to the maintenance work must be carried out every day, which may be a maintenance weekly, monthly or quarterly conducted. Maintenance work should be recorded. Maintenance work should be recorded, in order to facilitate future troubleshooting and handling.
Should check leaks using soap at various checkpoints and other measures applied, because of the leak display effect is more sensitive than listen to the sound.
Note should check valve exhaust air quality following three aspects: First, understand the lubricating oil contained in the exhaust gas whether appropriate, the method is a clean white paper close to the exhaust port on the valve, the valve after working three to four cycles, if only on a very light white spots, indicating that well-oiled, the second is to understand whether or not contained in the exhaust gas condensate, the third is to understand not to exhaust vent whether there is leakage. A small leak indicates early damage element (micro gap sealing valve leakage is the presence of normal). If the poor lubrication, chemical pumps should consider the installation position of oil mist is appropriate, the selected size is appropriate, adjust the amount of drip was reasonable and management practices to meet the requirements, if the condensed water is discharged, you should consider whether the position of the filter appropriate, in addition to various water element selection is reasonable and practical, condensed water management to meet the requirements. Mainly due to leakage within the valve cylinder seal or poor, insufficient air pressure. This system sealing valve leakage is large, it may be spool and sleeve due to wear and tear.
The cylinder piston rod often exposed. Observe whether the piston rod is scratched, corrosion and the presence of partial wear. According to whether the leak can be judged with the rod guide sleeve inside the front cover, exposure seal, deal with quality compressed air cylinders if there are lateral loads and so on.
Such as safety valves, emergency switch valve, casting molds rarely use. Periodic inspection must confirm their operating reliability.
Let solenoid valve repeatedly switching whether the sound can be judged from the switching valve is working properly. AC solenoid valves, if any beeps, you should consider moving core and static iron core is not completely pull, pull surface dirt, shading coil loss or damage.
