Transducer installation process
One.
1, prepared
According to the production task list, carefully check to make sure, the required bonding of the ultrasonic transducer (with a good pair), cylinder, mat, glue, etc. ready.
2, sandblast
Required for bonding to ultrasonic transducers block the sandblasting process, sandblasting adhesive junction should be wool, 30 the purpose of application of diamond sandblast sand, sand filter must be kept dry and often (each time into the sandbox to be screened), when the compressed air sandblasting pressure should be ≥ 6KG, and after the gas source processor, high-pressure air after dehumidification.
3, cleaning
Cylinder to a good spray of sand and ultrasonic cleaning transducer, transducer cleaning first with methanol, to remove surface dust and sand, etc., and then acetone to rinse; cylinder washed with water, and then, after pickling Rinse, dry and then with methanol and acetone to rinse, mat with a thickness of ≤ 0.15 ≤ 30 mesh stainless steel mesh as clean (conditional electrolytic processing) back.
4, drying, preheating
To good cleaning and ultrasonic transducer block and mat into the oven for drying, drying of 60 ℃ -80 ℃ 2 hours after drying to about 40 ℃, the cooling time for bonding. Bonding in all preparations ready, with a good glue (room temperature) to fully reconcile quickly after bonding.
5, bonding
a) the bonding process a good block on the plate put away, and then place the plastic with acetone and then wipe again with a cotton cloth.
b) to deal with a good ultrasonic transducer junction with acetone and then glue cotton cloth and then wipe again.
c) a good glue to fully reconcile with 1-2 minutes after the warm-up. (Each configuration can not be too much glue, glued to a 20-30 first date) glue is configured to 5G / head ratio of 1:0.4 (adhesive than the curing agent, should be as precise as possible).
d) the cylinder and the ultrasonic transducer is cooled to about 40 ℃, when bonding, bonding, respectively in the cylinder and the ultrasonic transducer evenly coated with glue on the middle to put the Internet cloth, and pressed hard, bonding faster, after the bonding glue each configured not exceed 10 minutes on time (to do the work required to prepare full). ,
e) After the pressure-treated plastic (with work wear, with soft spring pressure).
6, curing
Good clean plastic cylinder into the oven for curing, heat curing temperature is 40-50 ℃ curing time after 30 minutes, heated to 60-70 ℃ curing the second 30 minutes and then heated to 80 ℃ curing times 2 hours after curing 24 hours after detection of the natural connection. Heat curing temperature controller with a programmable intelligent.
7, detection
Good for curing detect ultrasonic transducer, each transducer (60W, 22,25,28 KHZ) the impedance of about 250Ω bonding around, can not exceed 300Ω, and testing the characteristics of the transducer (can not have mixed wave), with a cylinder on the ultrasonic transducer impedance value should be as close as possible the same, can not exceed the average of 20% (about ± 50Ω), do not meet the requirements of the ultrasonic transducer removal of re-bonding.
8, the connection
Detection of intact whole tank of ultrasonic transducer for connection, the connection application 75W soldering iron and reliable connection, can not have a cold solder joint, positive and negative application of different colored wire, positive wire should be yellow jacketed wax casing, and finally with heat shrink tube to trap all the joints.
Even after the good of the whole cylinder ultrasonic transducer for insulation testing: The use of Kyoritsu 3721 Digital megger, voltage 2500V, the entire cylinder above the insulation should be ≥ 1000MΩ (detection of air humidity ≤ 60%). Below this value should find out the reasons, re-processing.
Third, the glue of the storage
Glue should be placed in freezer stored, refrigerated temperature of 0-5 ℃, open cans at the end of the glue used and should be well covered with sealing tape and paste it into the freezer after the; should always check the durability against glue , so early into the morning with, resolutely do not expire.
Fourth, the environmental requirements
Ultrasonic transducer workshop should be kept clean, dry and sanitary environment, the workshop should be kept clean, dust, dehumidifier.
a) workshop temperature should be maintained at 15-20 ℃, humidity ≤ 50-60%.
b) Workshop cleaning at least once a day (application dragging, wiping), after cleaning the dehumidifier should be timely, clean.
c) Smoking is prohibited in the workshop, usually shut doors and windows.
d) ultrasonic transducer assembly with good clothes should be worn, white cotton gloves with a good, direct manipulation by hand is strictly prohibited.
e) oven should always wipe clean, in good condition.
f) The equipment should be kept clean with
