Pembahasan mesin pompa pom bensin (Dispenser SPBU)<\/strong> memerlukan tingkat ketelitian khusus karena melibatkan perpaduan sistem mekanis cairan, komputasi digital, dan sistem kelistrikan yang wajib memenuhi standar keamanan tingkat tinggi (Anti-Ledakan\/Explosion Proof)<\/strong>.<\/p>\n\n\n\n

KOMPONEN, WIRING DIAGRAM, & REPARASI DISPENSER BBM (POM BENSIN)<\/h2>\n\n\n\n

\u26a0\ufe0f ATURAN KESELAMATAN MUTLAK (SAFETY FIRST):<\/strong><\/p>\n\n\n\n

    \n
  • Zero Power Tolerance:<\/strong> Selalu matikan Molded Case Circuit Breaker (MCCB)<\/em> di ruang panel utama SPBU sebelum membuka bodi dispenser.<\/li>\n\n\n\n
  • Explosion-Proof Area:<\/strong> Semua komponen kelistrikan bawah (pompa\/motor) wajib bertipe Explosion-Proof<\/em> (Ex-d). Dilarang menyambung kabel secara terbuka di area bawah yang rentan uap bensin. Gunakan junction box<\/em> kedap udara.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    BAB I: SISTEM KERJA DISPENSER BBM<\/h2>\n\n\n\n

    Secara garis besar, ada dua jenis sistem instalasi SPBU: Sistem Suction (Pompa Hisap di dalam Dispenser)<\/strong> dan Sistem Submersible (Pompa Benam di dalam Tangki Pendam)<\/strong>. Modul ini berfokus pada jenis yang paling umum di lapangan, yaitu tipe Suction (Hisap)<\/strong>.<\/p>\n\n\n\n

    1. Alur Urutan Kerja Mekanis & Digital:<\/h2>\n\n\n\n
      \n
    1. Trigger Awal:<\/strong> Petugas mengangkat nozzle dari tempatnya (nozzle boot<\/em>), memicu magnetic switch<\/em> mengirim sinyal ke modul komputer utama (CPU).<\/li>\n\n\n\n
    2. Perintah Start:<\/strong> CPU mengaktifkan solenoid valve dan menyalakan Motor Listrik Utama untuk memutar pompa hisap (pumping unit<\/em>).<\/li>\n\n\n\n
    3. Pemisahan Udara:<\/strong> BBM dihisap dari tangki pendam menuju pumping unit<\/em>. Di dalam komponen ini, udara dipisahkan dari cairan agar perhitungan liter tetap akurat.<\/li>\n\n\n\n
    4. Penghitungan Volume:<\/strong> Cairan BBM murni ditekan menuju Alat Ukur (Flow Meter)<\/strong>. Di sini, aliran cairan menggerakkan piston yang terhubung dengan Pulser Sensor<\/strong>.<\/li>\n\n\n\n
    5. Konversi Data:<\/strong> Pulser<\/em> mengubah gerakan mekanis menjadi pulsa digital listrik dan mengirimkannya ke CPU untuk ditampilkan pada layar LCD sebagai data Liter dan Rupiah.<\/li>\n\n\n\n
    6. Output:<\/strong> BBM keluar melalui pipa fleksibel (hose<\/em>) menuju nozzle<\/em> untuk diisikan ke kendaraan.<\/li>\n<\/ol>\n\n\n\n
      \n\n\n\n

      BAB II: DAFTAR KOMPONEN UTAMA & SPESIFIKASI FUNGSI<\/h2>\n\n\n\n
        \n
      1. CPU Board (Modul Kontrol Utama):<\/strong> Otak elektronik dispenser yang memproses data dari pulser, mengatur kalkulasi harga per liter, menampilkan angka pada LCD display, dan mengendalikan relay pompa.<\/li>\n\n\n\n
      2. Pulser Sensor (Encoder):<\/strong> Komponen optik\/magnetik yang membaca putaran poros flow meter<\/em> dan mengubahnya menjadi sinyal digital (pulsa listrik). 1 Liter BBM setara dengan jumlah pulsa tertentu (misal: 100 pulsa\/liter).<\/strong><\/li>\n\n\n\n
      3. Pumping Unit \/ Vane Pump:<\/strong> Pompa tipe baling-baling yang berfungsi menyedot BBM dari tangki bawah tanah. Dilengkapi air separator<\/em> (pemisah udara) dan katup bypass tekanan.<\/li>\n\n\n\n
      4. Flow Meter (Alat Ukur):<\/strong> Komponen mekanis presisi tinggi (sistem piston ganda) untuk mengukur volume cairan yang lewat secara akurat. Komponen ini memiliki segel resmi dari dinas metrologi.<\/li>\n\n\n\n
      5. Solenoid Valve:<\/strong> Katup listrik dua tahap (two-stage<\/em>). Berfungsi menutup aliran BBM dengan presisi tinggi saat pengisian mendekati target rupiah\/liter agar tidak kelebihan (overrun<\/em>).<\/li>\n\n\n\n
      6. Nozzle Switch:<\/strong> Sakelar magnetik (reed switch<\/em>) di dalam dudukan nozzle untuk mendeteksi apakah nozzle sedang diangkat atau diletakkan.<\/li>\n<\/ol>\n\n\n\n
        \n\n\n\n

        BAB III: DIAGRAM KELISTRIKAN & WIRING JALUR UTAMA<\/h2>\n\n\n\n

        Sistem kelistrikan dispenser dibagi menjadi dua area tegas: Area Atas (Electronic Head – Aman dari Uap)<\/strong> dan Area Bawah (Hydraulic Area – Rawan Uap)<\/strong>.<\/p>\n\n\n\n

          Gejala Masalah<\/th>Dicurigai Pada Komponen<\/th>Prosedur Solusi & Analisis Teknisi<\/th><\/tr>
          Nozzle diangkat, angka LCD tidak reset ke nol, motor tidak berputar<\/strong><\/td>Nozzle Switch<\/em> atau Kabel Sinyal Putus.<\/td>1. Cek magnet pada tuas nozzle boot, pastikan tidak lepas.
          2. Lepas soket nozzle switch<\/em> di CPU, ukur dengan multimeter skala Ohm kontinu. Saat tuas diangkat, sakelar harus terhubung (Short<\/em>). Jika tetap Open<\/em>, sakelar rusak.<\/td><\/tr>
          Motor berputar, tapi BBM tidak keluar\/mengalir sangat lambat<\/strong><\/td>Pumping Unit<\/em> (Masuk angin) atau Solenoid Valve<\/em> macet.<\/td>1. Buka baut buang udara (air vent<\/em>) pada pompa untuk membuang sumbatan udara.
          2. Periksa filter strainer di dalam pompa bawah, bersihkan dari endapan lumpur tangki.
          3. Cek pasokan listrik ke solenoid valve<\/em>. Jika listrik 220V masuk tapi katup tidak membuka, koil solenoid terbakar.<\/td><\/tr>
          BBM keluar deras, tapi angka Liter pada LCD tidak berjalan<\/strong><\/td>Pulser Sensor<\/em> rusak atau kopling penghubungnya patah.<\/td>1. Buka kap atas, cek poros penghubung mekanis antara flow meter<\/em> dan pulser<\/em>. Pastikan tidak patah\/lepas.
          2. Ukur tegangan VCC pulser dari CPU. Jika tegangan normal tapi tidak ada pulsa gelombang keluar saat poros diputar, Pulser wajib diganti<\/strong>.<\/td><\/tr>
          Jumlah literan tekor \/ tidak pas saat ditakar dengan Bejana Ukur Metrologi<\/strong><\/td>Flow Meter<\/em> (Mekanikal haus\/berubah).<\/td>1. Ini ranah kalibrasi. Lakukan tera ulang\/kalibrasi<\/em> dengan memutar roda gigi\/piston kalibrasi pada flow meter<\/em> menggunakan obeng khusus setelah segel metrologi dibuka petugas berwenang.
          2. Jika diputar tetap tekor, seal piston bagian dalam flow meter<\/em> sudah aus dan bocor dalam.<\/td><\/tr>
          Layar LCD berkedip atau angka acak saat motor utama menyala<\/strong><\/td>Gangguan Noise<\/em> Kelistrikan \/ Grounding<\/em> Buruk.<\/td>1. Pastikan jalur kabel data (Pulser & LCD) menggunakan kabel jenis shielded<\/em> (berpelindung aluminium) agar tidak terinduksi medan magnet motor.
          2. WAJIB:<\/strong> Ukur tahanan grounding<\/em> dispenser ke bumi menggunakan Earth Tester. Nilai grounding harus di bawah 1 Ohm<\/strong> demi kestabilan data CPU dan keamanan dari petir\/listrik statis.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
