ball-type gas turbine operating practices

ball-type gas turbine operating practices, common faults and troubleshooting
First, the operating practices

1. Turbine drive air pressure for the compressed air input into the mobile phone must be dry and clean, the air pressure in the 0.25-0.32MPa, otherwise, the pressure is too low, dental hand piece the phone weak rotation, pressure is too high, speed mobile bearing wear.
2. Correct loading unloading bur bur reed folder must fully open state to avoid damaging the clamp axis.
3. The use of qualified mobile clip bur bur shank diameter shaft on very stringent requirements must be 1.59mm-1.60mm.
4. Before turning the phone ventilation must hold a qualified bur reed in a relaxed state so as not to clip under high-speed rotation damaged.
5. Using the international standard burs. Even slightly bent needle, defect, it must be replaced immediately to avoid shortened bearing life.

        (A), maintenance
       1, clean
        (A) before loading and unloading trucks needle probe clean water fumaroles near debris
        (2) provided by the manufacturer of the cleaning solvents used internally and externally.

2, lubrication
Grease is ideal for mobile phones bearing lubrication tools, then there is pressure spray tank, the effect is better, and easier to operate. But be sure to use the manufacturer's recommended lubricant is appropriate.
        (A) in accordance with the manufacturer's operating manual, the phone requires lubrication.
        (2) Each autoclavable, it shall be on the phone for routine cleaning and lubrication maintenance to extend the life of the phone.
        (3) the hand spray tank with quick coupling lubrication method ① head phones, put pressure spray tank nozzle into the phone connector. ② 2 holes phones, big hole injection nozzle aligned. ③ 4 holes phones, nozzle holes aligned with the second largest jet. ④ amount of fuel specified by the manufacturer should also be operational, not too small, nor do they need too.
        (4) Use grease Methods ① Remove the phone by the interface, remove the needle. ② remove grease stick shield, axle grease stick into the folder, methods, and on the same needle. ③ fat rods rotating knob, for the first time you use the cell phone revolution; thereafter, each half turn. ④ Load bur, low speed rotation 10-15 seconds, so that the axis is fully lubricated.

        3, disinfection
        Phone is the denture teeth main way to cause cross-infection.
        (1) Clean and lubricate before disinfection phone with a clean paper bag sealed.
        (2) be placed in sterilized pot 135 ℃, sterilized for 15 minutes.
        (3) Remove after disinfection, do not sterilize the pot overnight.
(4) use of paper and then cut. 
    Second, common faults and troubleshooting
    Symptom
    Possible Causes
    Remedy
    Phone weak rotation
    Less than the rated working pressure
    Adjust air pressure to the rated
    Needle worn or bent
    Replace qualified bur
    Bearings are dirty or damaged
    Clean or replace bearings
    No cooling mist
    Water holes or pores clogged nose
    Dredge with a probe with a random water, air holes
Mobile tail leaking
    Substandard treatment station pipeline joints, causing screw is not tight, strict closure
    Replacement of qualified joint; or seals and gaskets
    Bur loose
    Check the needle is in compliance with international standards
    Replacement of qualified bur; no effect timely delivery of professional maintenance company maintenance
    Use of vibration
    Bearing wear or bump
    Send manufacturer designated repair maintenance
