Instalasi awal saka EMT-RCC Kupon Korosi Adjustable

The product is transported as a whole when leaving the factory, with all components already assembled (including the welded base) and having passed a pressure test. Therefore, during installation, the user must unscrew and separate the welded base from the connection with the valve, weld it to the designated position on the pipe (pre-drilled diameter φ27~30mm), measure the distance L0 as shown in Figure 2, adjust the spacing L1 of the safety clamps (as shown in Figure 2), then install the corrosion coupon system onto the base, adjust the positioning distance L and the direction of the coupon, and tighten the upper and lower safety clamps. The installation is then complete. The specific steps are as follows:

(1) Persiapan Sadurunge Instalasi

Gawe bolongan kira-kira φ27 nganti 30 mm ing papan sing direncanakake ing pipa. Sawise sampeyan wis ngebor bolongan, Gamelan metu sembarang sudhut kasar utawa bit kiwa konco. Uga, priksa manawa kanggo ngresiki kabeh karat saka wilayah sing arep dilas.

(2) Pemisahan Base Welded

Unscrew basa gandheng saka sistem kupon karat, misahake ing prapatan antarane basa gandheng lan tutup (antarane item 5 lan 6 ing Figure 1). Gunakake kunci pas kanggo ndandani awak tutup lan kunci liyane kanggo nyopot dhasar sing dilas.

(3) Welding of the Welded Base (Item 6 ing gambar 1)

Selarasake dhasar sing dilas karo bolongan sing dilatih (jejeg ing tengah pipa lan tembok lan konsentris karo bolongan), banjur las menyang pipa.

(4) Nemtokake Jarak Instalasi L

Sawise sampeyan wis rampung welding basa, sampeyan kudu ngukur jarak maksimum saka ndhuwur basa gandheng kanggo nang saka pipo. Gunakake rod probe kanggo iki utawa ukur langsung. Nalika ngukur, priksa manawa rod probe ngadeg ing sudut tengen menyang tengah pipa lan tembok njero. Iki minangka jarak sing dilabeli minangka L0 ing Figure 2. Sabanjure, etung jarak posisi, L, kanthi nyuda 10 mm saka L0. Akibaté, L = L0 minus 10 mm. Tulis jarak posisi iki lan tetep aman. Sampeyan mbutuhake informasi iki nalika nginstal lan njaga kupon ing mangsa ngarep.

(5) Nyetel Jarak Clamp Safety

Pisanan, tweak nut ngunci ing clamp safety ngisor. Banjur, referring kanggo 5-7mm kadohan ditampilake ing Figure 2, aman loro bolts kanggo ngawat-ngawati safety ngisor.

Sabanjure, atur kacang ing loro-lorone clamp safety ndhuwur. Iki bakal ngganti longkangan antarane loro Clamps safety. Sampeyan ngarahake jarak 90-95 mm, sing dituduhake minangka L1 ing Gambar 2.

Sawise sampeyan nindakake pangaturan kasebut, perakitan sampeyan wis siyap.

(6) Pasang Material Sealing

Copot bahan sealing sing isih ana saka permukaan benang katup lan benang dasar sing dilas. Bungkus maneh materi sealing ing benang njaba tutup.

(7) Pasang Sistem Kupon Korosi

Sambungake sistem kupon karat karo basa gandheng (iki mbutuhake wong loro). Priksa manawa Utas wis didadekake siji lan ngaco ing, muter sistem kupon korosi nganti ora bisa mindhah, banjur ngencengi tutup karo kunci.

(8) Nyetel kupon korosi menyang posisi instalasi pungkasan

Adhedhasar jarak L sing diwilang ing langkah (4) saka bagean iki, atur jarak antarane clamp safety ndhuwur lan permukaan warata saka basa gandheng kanggo jarak posisi L (nalika jarak antarane clamp safety ndhuwur lan lumahing warata saka basa gandheng luwih saka L0, clamp safety ndhuwur kudu diatur mudhun kanggo witjaksono jarak L). Iki minangka jarak minimal, yaiku, ambane maksimal kupon korosi menyang pipa. Iki mesthekake yen sawise sistem kupon dipasang ing pangkalan, ujung ngisor kupon korosi cedhak karo ngisor pipa nalika njaga jarak sing aman.

(9) Nyetel Arah Kupon Korosi

Gunakake kunci kanggo nyetel arah lumahing indikator kupon karat (Gambar 3) ing ndhuwur rod support coupon, mesthekake yen lumahing indikator madhep arah aliran medium nang pipe. (Ing titik iki, arah jembar kupon korosi sejajar karo arah pipa.)

(10) Kencengake kacang imbuhan saka clamp safety ndhuwur; mriksa lan ngencengi perkakas ngunci clamp safety ngisor. Panginstalan wis rampung.

Pembongkaran lan Pemriksaan Pangopènan Sistem Kupon Korosi EMT-RCC sing bisa diatur

Nalika mbongkar sistem kupon saka pipa kanggo pengawasan pangopènan, tindakake langkah ing ngisor iki.

(1) Setel klem safety ndhuwur menyang posisi ing ngendi tutup ditutup.

Loosen the two nuts on the upper safety clamp, adjust the nuts to the distance L2 as shown in Figure 4, L2 = 515~525mm, then stop.

When there is pressure inside the pipe, the corrosion probe support rod will be pushed upwards as the nuts are loosened. If the coupon support rod does not pop up as the nuts are loosened, check by twisting the coupon support rod to see if it is jammed, to prevent a sudden burst under internal pressure, causing injury.

Note: Two people can operate simultaneously to unscrew the nuts, or one person can unscrew the two nuts alternately (alternate operation every 1 to 2 turns).

Under the pressure inside the pipe, the corrosion coupon support rod should be able to pop out as the nuts are loosened. If it doesn’t pop out, check and handle it promptly to ensure safe operation.

(2) Close the valve.

Rotate the valve handle to the closed state.

Note: Before closing the valve, you must confirm the distance L2, L2=515~525mm, to prevent the valve from being affected by a small L2 distance or causing damage to internal parts.

(3) Disassemble the sealing nut of the coupon system.

Ndandani pipa cabang (No. 4 ing Figure 1) ing ndhuwur tutup kanthi kunci. Gunakake kunci liyane kanggo nguripake nut sealing counterclockwise. Sawise ngeculake, gunakake tangan kanggo nguripake, misahake nut sealing lan bagean ing ndhuwur kanthi wutuh, lan sijine kanthi aman.

(Cathetan: Operasi iki mbutuhake wong loro.)

Kanthi operasi iki, sistem kupon bisa dicopot saka basis sing dilas lan pipa, lan karya disassembly rampung.

(4) Mbongkar Kupon Korosi

Yen perlu kanggo mbongkar kupon korosi, sampeyan kudu nyetel kacang ing clamp safety ndhuwur piranti kupon korosi, ngurangi jarak antarane loro clamps safety, nganti kupon korosi lan kacang mbenakake kupon korosi rampung metu saka nut sealing. Dawane extension kudu cukup kanggo nggampangake pembongkaran kacang sing ndandani kupon korosi. Deleng negara ing Gambar 5.

Copot kacang sing mbenakake kupon korosi, copot kupon korosi, lan tindakake pemeriksaan utawa panggantos sakteruse.

Instalasi maneh saka EMT-RCC Kupon Korosi Adjustable

Sawise panggantos kupon korosi rampung utawa diinstal maneh sawise karya inspeksi, nerusake instalasi maneh piranti kupon.

(1) Konfirmasi apa rod imbuhan diatur ing panggonan.

Measure and adjust the distance between the two safety clamps (important), it should meet L2=515~525mm in Figure 4. If it does not meet this criterion, adjustments should be made to this range. (Note: Keep the lower safety clamp stationary during the adjustment process, only adjust the upper safety clamp during the adjustment process.)

(2)Replace the sealing material.

Clear the residual sealing material at the branch pipe threads and the sealing nut, and wrap new sealing material at the branch pipe threads.

(3)Install the coupon device.

Align the coupon device with the branch pipe threads, hand-tighten until it doesn’t move, then use a wrench to tighten the sealing nut.

(4)Open the Valve.

Sawise mbukak tutup, priksa manawa ana bocor ing sambungan pipa cabang lan sambungan benang liyane. Yen ana bocor, tutup tutup, banjur ngatasi segel bocor (ganti materi sealing utawa ngganti bagean, njaga lan nginstal maneh). Yen isih ana bocor, baleni langkah iki nganti ora ana bocor.

(5) Nyetel klem safety ndhuwur menyang posisi instalasi wiwitan.

Nyetel nut imbuhan ngisor saka ngawat-ngawati safety ndhuwur kanggo posisi paling, lan sakcepete nyetel nut iki nalika mengaruhi imbuhan saka nut imbuhan ndhuwur.

Nyetel kadohan antarane ngawat-ngawati safety ndhuwur lan lumahing basa gandheng kanggo instalasi dhisikan rekaman jarak L, ndeleng langkah (4) saka instalasi dhisikan.

Nalika nyetel kacang, wong siji bisa operate gantian kanggo ngencengi loro perkakas; utawa wong loro bisa bebarengan ngencengi loro perkakas, nyoba kanggo njaga clamp safety ndhuwur jejeg rod support coupon supaya ngiringake gedhe banget.

(6) Kunci Rod Dhukungan Kupon.

Sawise clamp safety ndhuwur diatur ing panggonan, mriksa arah rod support kupon, nguripake rod support kupon supaya lumahing indikator (Figure 3) nuding ing arah aliran medium pipo.

Kencengake kacang imbuhan ndhuwur lan ngisor saka clamp safety ndhuwur, priksa lan kenceng nut kunci saka clamp safety ngisor. Instalasi wis rampung.

Kanthi iki, proses instalasi maneh rampung.
