1. Cov khoom siv: 1. Hluav taws xob cua sov daim kab xev
2. PE nplaum nplaum (yuav tsum tau yuav thiab siv)
2. Construction tools and accessories: electric welding machine, stainless steel buckle, U-clamp, wool buckle, rubber hammer,
Cov hnab looj tes insulated, cov xov hlau, cov ntsuas kub saum npoo.
3. Cov txheej txheem ua haujlwm:
1. Muab ob lub kav dej los tsim tawm hauv av thiab ua kom cov kab rov tav.
2. Tshem tawm cov av, noo noo thiab lwm yam khib nyiab uas lo rau saum npoo ntawm cov yeeb nkab.
3. Siv woolen buckle daim kab xev los qhwv cov hluav taws xob cua sov melting daim kab xev rau ntawm qhov sib txuas ntawm cov yeeb nkab thiab qhwv nws kom nruj, thiab muab qhov kawg nrog lub davhlau ya nyob twg rau ntawm txheej txheej ntawm lub puab tsaig. Xyuas kom tseeb tias cov yeeb nkab seam yog nyob rau hauv nruab nrab ntawm cov hluav taws xob fusion siv.
4. Wrap the stainless steel buckle on the electric heating tape and fasten it with a U-shaped clamp, insert the PE glue stick into the lap joint of the electric heating melting tape, and tighten the stainless steel buckle so that the electric heating melting tape is tightly attached to the pipe. on the wall.
5. Connect the power supply of the electric heating fusion welding machine to the electric heating melting belt, start the electric heating fusion welding machine after setting the heating time, and carefully adjust the heating current. Difference, (refer to the attached table for heating time and current). During the heating process, the electric heating melting tape can be tightly attached to the surface of the pipe by inserting the flat mouth and changing the knife.
6. When the electrothermal melting process is completed (the temperature of the temperature measuring point on the electrothermal melting belt will reach about 92°C, the heating time should be extended if the temperature is too low.), turn off the power, and properly tighten the stainless steel buckle again.
7. Tom qab lub tshuab hluav taws xob cua sov melting siv tau txias tag (saib cov lus txuas rau lub sijhawm txias), tshem tawm cov hlau stainless buckle thiab kev tsim kho tiav.
4. Cov teeb meem kev nyab xeeb
1. Cov hnab looj tes insulating yuav tsum hnav thaum siv. Thaum cov pob qij txha ntub, vuam yuav tsum tsis txhob ua kom tsis txhob muaj hluav taws xob poob.
2. Tsis txhob scalding tib neeg lub cev los ntawm qhov kub-kub sib koom ua ke tom qab electrothermal fusion.
