Ultrasonic Cleaner transducer installation steps

Ultrasonic Cleaner transducer installation steps
A.
1, prepared
In accordance with the requirements of the consumer obligations single, carefully reflect on confirmation, required bonding ultrasonic transducer (with a good pair), cylinder, mat, glue ready.
2, sandblasting
Required glued ultrasonic transducer, the cylinder stop sandblasting disposal sandblasting glue the junction should try hair, sandblasting using 30 mesh carborundum, sand must adhere boring and often selected (each into the sandbox to be selected), sandblasting tightening the pressure of the air should be ≥ 6KG, and after high-pressure air in the disposal of gas source dehumidified.
3, cleaning
Stop cleaning sprayed sand cylinder and ultrasonic transducer, transducer first stop cleaning with methanol to remove the appearance of sand and other dust stop rinsed with acetone; cylinder water washed first, then pickling Rinse clean, dry it and then with methanol and acetone each stop once rinsed, mat thickness of ≤ 30 mesh ≤ 0.15 stainless steel mesh strange cleaned Electrolytic disposal) (conditional spare.
4, drying, preheating
Cleaning the ultrasonic transducer and the cylinder block and the network pad stop placed in an oven drying, drying for 60 ℃ -80 ℃ drying After 2 hours, cooled to about 40 ℃ stop glued. After all glued preparatory tasks well, plenty and harmony with good glue (room temperature) after the move to stop glued.
5, glued
a) on the disposal of a good cylinder glue then plates put away, and glued with acetone at cotton cloth and then wipe the again.
b) the disposal of good ultrasonic transducer gum surface with acetone and then cotton smear again.
c) with a good glue with plenty of harmony after a warm-up for 1-2 minutes. (Each glue configuration can not be too much to 20-30 head glued prevail) glue 5G / head ratio of 1:0.4 (adhesive than the curing agent should be as accurate as possible).
d) cooling the cylinder block and the ultrasonic transducer to about 40 ℃ stop glued glued to identify when they put glue on average in the cylinder and the ultrasonic transducer, the two put online cloth, and then forced to compress glued faster, each configuration glue glued the day should not exceed 10 minutes (do require preparatory tasks plenty). And
e) After the glue stop pressure disposal (need to sing tooling, soft spring pressure).
6, curing
The gum good cylinder placed in a clean oven to stop the curing, curing temperature once warmed to 40-50 ℃ cured for 30 minutes, the secondary 60-70 ℃ cured for 30 minutes and then warmed to three warmed to 80 ℃ Curing natural cure for 24 hours after the two hours after the detection of the connection. Curing heating with programmable intelligent temperature control instrument control.
7, detection
Cured stops detecting ultrasonic transducer, each transducer (60W, 22,25,28 KHZ) glued impedance of about 250Ω about can not exceed 300Ω, and transducer characteristics Stop Detection (can not have miscellaneous wave), with a cylinder on the ultrasonic transducer impedance values ​​should be as close as possible to their differences, can not exceed 20% of the value of the uniform (± 50Ω) does not fit the requirements of the ultrasonic transducer removal re-glued.
8, the connection
Detection and crippled the entire cylinder ultrasonic transducer stop connection, connection to use 75W soldering iron solid convergence, not Weld positive and negative wire using a different color, positive line should jacketed Huanglashi casing, initially with hot shrink tube entangle everything connectors.
Stop even after the entire cylinder ultrasonic transducer insulation testing: use with Kyoritsu 3721 Digital megger measurement, voltage 2500V, the entire tank insulation ≥ 1000MΩ and (detecting air humidity ≤ 60%). Find a reason to be less than this value, re-disposal.
Third, the glue storage
Glue should be placed in the freezer storage, refrigeration temperatures 0-5 ° C, the end of the open cans run out of glue should cap sealing tape, stickers, ready to put into the freezer; should always reflect on the shelf life of the control glue , so early into the early use maturity resolutely do not have to.
Fourth, the environmental requirements
Ultrasonic transducer workshop should often insist on a clean, dry and hygienic environment, the workshop should always cleaning, dusting, dehumidifiers.
a) workshop temperature should insist on at 15-20 ° C, humidity ≤ 50-60%.
b) Workshop less than once a day cleaning (using a mop, wipe), cleaning should dehumidifiers, pollution.
c) non-smoking workshop usual closed doors and windows.
d) demolition of ultrasonic transducer should wear with good task suit, with a good white cotton gloves, non-hand indirect.
e) oven should always wipe clean, adhere to good shape.
f) utensils should be used often insist on clean

Third, the glue storage
Glue should be placed in the freezer storage, refrigeration temperatures 0-5 ° C, the end of the open cans run out of glue should cap sealing tape, stickers, ready to put into the freezer; should always reflect on the shelf life of the control glue , so early into the early use maturity resolutely do not have to.
Fourth, ultrasonic cleaning machine the transducer installation environment requirements
Ultrasonic transducer workshop should often insist on a clean, dry and hygienic environment, the workshop should always cleaning, dusting, dehumidifiers.
a) workshop temperature should insist on at 15-20 ° C, humidity ≤ 50-60%.
b) Workshop less than once a day cleaning (using a mop, wipe), cleaning should dehumidifiers, pollution.
c) non-smoking workshop usual closed doors and windows.
d) demolition of ultrasonic transducer should wear with good task suit, with a good white cotton gloves, non-hand indirect.
e) oven should always wipe clean, adhere to good shape.
f) used utensils should always adhere to clean.Ultrasonic Cleaner transducer installation steps
