When some hands-on users use the ultrasonic cleaning machine failure is often not sent back to the manufacturer to repair, but to repair their own hands to see, and ultrasonic cleaning machine in the installation, the need to pay attention to more problems, if the installation problems will lead to the normal use of the instrument. Today mainly to introduce some ultrasonic cleaning machine installation and operating procedures, I hope to help users better application of the product.
Ultrasonic cleaning machine installation steps.
The required glued ultrasonic transducer (with a good pair of), cylinder, mesh pad, glue and other preparations.
The required gluing of the ultrasonic transducer, cylinder stop sandblasting disposal, sandblasting gluing surface should be as gross as possible, sandblasting using 30 purpose diamond sand, sand must adhere to dry and often selected (each time into the sand box are selected), sandblasting when the pressure of the compressed air should be ≥ 6KG, and after the air source disposer dehumidification of high pressure air.
The ultrasonic cleaning machine disposed of the cylinder and ultrasonic transducer to stop cleaning, transducer first with methanol to stop cleaning, the appearance of sand and other dust removed, and then use acetone to stop rinsing; cylinder first flush with water, then rinse clean after acid cleaning, cool dry and then use methanol and acetone to stop rinsing each time, mesh pad with ≤ 30 mesh thickness ≤ 0.15 stainless steel mesh is cleaned (electrolytic disposal when available) Standby.
Put the cleaned ultrasonic transducer and cylinder and mesh pad into the oven to stop drying, drying for 60 ℃ -80 ℃ drying 2 hours after cooling to about 40 ℃ to stop gluing. After all the gluing preparatory tasks, with a good glue (room temperature) and full harmony after the speedy stop gluing.
a. Put the disposed cylinder on the gluing plate, and use acetone in the gluing place with a cotton cloth to wipe again.
b. Dispose of the ultrasonic transducer gluing surface with acetone and then wipe again with cotton cloth.
c. With a good glue and full harmony after preheating 1-2 minutes. (Each configuration of the glue can not be too much, to a gluing 20-30 head shall prevail) glue configuration for 5G / head, the ratio of 1: 0.4 (adhesive than hardener, should be as accurate as possible).
d. The cylinder and ultrasonic transducer cooled to about 40 ℃ when stop gluing, gluing when the cylinder and ultrasonic transducer in the average coated with glue, both ends put on the net, and then press hard, gluing speed to fast, each configuration of the glue after gluing days do not exceed 10 minutes on (required to do the preparatory tasks adequately).
e. After the glue to stop the pressure disposal (need to sing work, with spring soft pressure).
Gluing good cylinder into the dust-free oven to stop curing, curing temperature once heated to 40-50 ℃ curing 30 minutes, the second heated to 60-70 ℃ curing 30 minutes and then three times heated to 80 ℃ curing 2 hours after the natural curing 24 hours after the test line. Curing heating with program-controlled intelligent temperature control instrument control.
Cured ultrasonic transducer to stop testing, each transducer (60W, 22, 25, 28KHZ) glued impedance of about 250Ω, can not exceed 300Ω, and the transducer characteristics to stop testing (can not have noise), the same cylinder on the ultrasonic transducer impedance value should be as close as possible to divergence, can not exceed the uniform value of 20% (about ± 50Ω), does not meet the requirements of Ultrasonic transducer removed and re-glued.
Ultrasonic cleaning machine only to make a reasonable installation, can carry out a normal operation, will not bring some ultrasonic cleaning machine work of the afterthought.
