Pemadam kebakaran aerosol dipasang pada lokomotif kereta api

Lokomotif kereta api memiliki ratusan tahun sejarah pembangunan dan bertahun-tahun inovasi teknis, hari ini kita berbicara tentang proteksi kebakaran lokomotif kereta api, Pertama, kita harus berbicara tentang pengetahuan tentang lokomotif kereta api.

Pengetahuan tentang lokomotif kereta api dan rolling stock

Lokomotif kereta api itu sendiri tidak memiliki perangkat listrik, whether it is a passenger locomotive or freight locomotive, we must connect many carriages to form a train, then it can move only after being pulled by a locomotive. Karena itu, the locomotive is the basic power of railway transportation.

Ada banyak jenis lokomotif yang digunakan di kereta api, according to the original power of the locomotive, there are Steam locomotives, diesel locomotives, and electric locomotives.

Lokomotif Uap

The application of steam locomotives has a history of more than 170 tahun. It converts the heat energy of a fuel (batu bara, minyak, kayu) into mechanical energy through a steam engine,

It converts the heat energy of a fuel (batu bara, minyak, kayu) into mechanical energy through a steam engine, to make the train move. The steam locomotive is mainly composed of a boiler, turbin uap, bingkai, kendaraan air batubara, alat prerangkai, buffer device, and braking device.

Lokomotif uap memiliki karakteristik efisiensi termal yang rendah, large energy consumption, and small transmission capacity, sehingga telah dihapus di dunia saat ini.

Lokomotif Diesel

A diesel locomotive is a locomotive powered by a diesel engine, its characteristics are high thermal efficiency, waktu kerja terus menerus yang lama, cocok untuk operasi jarak jauh.

The diesel locomotives currently used can be divided into electric drive and hydraulic drive styles.

• For electric drive, it is driven by the diesel engine to turn mechanical energy into electric energy, mensuplai energi listrik ke motor traksi, and then transmitting it to the locomotive gear to make the locomotive run.
• Hydraulic drive is equipped with a set of hydraulic transmission devices between the diesel engine and the locomotive driving wheel. The torque output by the diesel engine is transmitted to the locomotive wheelset through the transmission device to make the locomotive produce traction.

Lokomotif Listrik

Concept and Description of Electric Locomotives

The electric locomotive itself does not carry electric energy, itu tergantung pada perolehan energi listrik dari kabel catenary di sepanjang jalan, it is driven by a traction motor.

Pembangkit listrik mengirim 110 untuk 220 kv frekuensi daya tiga fase daya AC melalui saluran transmisi ke gardu traksi kereta api, yang memasok 25 untuk 27.5 kv single-phase power frequency AC power to the catenary for electric locomotives.

An electric locomotive is mainly composed of the vehicle body, perlengkapan lari, rangka bawah, coupler dan perangkat penyangga, braking device, and a complete set of electrical equipment.

The electric locomotive has the advantages of large power, kecepatan awal yang cepat, pandai memanjat, mudah diimplementasikan dengan kecepatan tinggi dan beban berat.

Saat sekarang, due to the extensive development of electric power and the continuous development of new energy power, lokomotif listrik telah menjadi yang paling banyak digunakan.

Rel kecepatan tinggi, kereta bawah tanah, and light rail we use are all driven by electric locomotives.

Fire Protection Issues and Solutions for Electric Locomotives

Namun, apapun jenis lokomotifnya, termasuk lokomotif listrik, mereka akan menghasilkan banyak panas saat beroperasi.

Ada banyak jalur pipa di lokomotif dan ruangnya sangat terbatas, mudah menyebabkan pelarian termal dalam kondisi bergerak lama, aging of the line, and high temperature of the weather.

The loss of a locomotive caused by fire after a thermal runaway is huge, dan kerugian ekonomi adalah ribuan dolar. Karena itu, kita perlu mempertimbangkan masalah pencegahan kebakaran lokomotif, dan perlu untuk memilih sistem proteksi kebakaran lokomotif yang sesuai.

Seperti yang kami sebutkan sebelumnya, there are many locomotive pipes and networks on the expensive railway locomotive and its space is very limited, Jadi sistem pencegah kebakaran yang dipasang harus memiliki karakteristik sebagai berikut:

• No damage to the locomotive pipeline, parts, or engine compartment.
• Volume produk harus kecil, dan itu tidak akan menempati banyak ruang.
• Mudah untuk menginstal dan men-debug sistem.
• Respon sensitif. Once the railway locomotive gets getting thermal runaway, perlu mengambil tindakan untuk segera memadamkan nyala api.

Saat sekarang, large-scale gas, busa, and water-mist fire extinguishing systems are not suitable for railway locomotives. dua produk sisanya kemungkinan besar menjadi pilihan proteksi kebakaran lokomotif, adalah: aerosol fire protection atau sistem supresi tabung jejak api.

Dengan ini mari kita bandingkan kedua sistem ini: the Aerosol System and the Fire Trace System.

Untuk Sistem Aerosol

The Aerosol system has the following main advantages:

• Ini tanpa pipa dan tanpa tekanan untuk bekerja.
• Releasing clean aerosol-forming agent.
• Ukurannya sangat kecil dan kompak, normally installed inside the engine compartment of a locomotive.

For the Fire Trace System

Sistem jejak api memiliki keuntungan utama sebagai berikut:

• It has white or red pipes for transporting fire extinguishing agents.
• It normally works with 1 untuk 5 Tekanan mpa.
• Melepaskan HFC-22yea atau NOVEC yang bersih 1230 (FK 5112) pemadam agen.
• It has a larger size than the aerosol device.
• Secara umum, its installation position is on the outside of the electrical cabinet or engine compartment.

Karena itu, considering the above features from the perspective of safety and convenience aerosol fire extinguishing systems will be more suitable for railway locomotives.

Many people worry that they don’t know how to install aerosol systems on railway locomotives it is very simple to install on the railway locomotive. Umumnya, the aerosol device has its mounting bracket, clamp, and screw, cukup bor beberapa lubang pada posisi yang tepat di lokomotif (biasanya posisi rawan kebakaran), dan kemudian perbaiki dengan braket pemasangan.

Ada juga cara yang lebih nyaman untuk menginstal, itu adalah, untuk menginstal dengan adsorpsi magnet, dan langsung pasang alat pemadam api ke plat besi mesin lokomotif.

Di kabel, sambungkan alat pemadam api dengan kabel lunak ke baterai di lokomotif, lalu pasang tombol start dan perangkat alarm di lab, Sesederhana itu!

Our dealers around the world have many installation cases, in the following we list some of them:

• Kereta berkecepatan tinggi China.
• Rel Wuhan Cina.
• Singapore rail.
• Kereta berkecepatan tinggi bintang Euro.
• Kereta berkecepatan tinggi Thailand.
• Bandung High-Speed Rail.
• Kereta Api Afrika Selatan.

Choosing an aerosol fire suppression system as a railway locomotive fire protection solution is feasible.
