This well submersible pump is a pump suitable for clean water. Digging new wells and pumping sediment and turbid water are strictly prohibited. The voltage grade of the well pump is 380V/50HZ. Submersible motors with other voltage grades need to be customized. Underground cables must use waterproof cables and must be equipped with starting equipment, such as distribution boxes, etc. The starting equipment should have common comprehensive motor protection functions, such as overload short circuit protection, phase loss protection, undervoltage protection, grounding protection and idling protection, etc. In abnormal cases, the protection device should be tripped in time. During installation and use, the pump must be reliably grounded. It is prohibited to push and pull the switch when hands and feet are wet. The power supply must be cut off before installation and maintenance of the pump. The place where the pump is used must be set up with obvious "anti-electric shock" marks. Before going down the well or installation, the motor must be injected with distilled water or non-corrosive clear cold water in the inner cavity, and the intake/drain bolts must be tightened. When testing the pump on the ground, water must be injected into the pump chamber to lubricate the rubber bearings. The instant start time should not exceed one second to check whether the direction is correct. The same as the steering instructions. Pay attention to safety when the pump is upright to prevent tilting and injury. Strictly in accordance with the provisions of the pump lift and flow range, to prevent the pump flow at low lift or in high lift pull too large, resulting in extreme wear of thrust bearings and other components, the motor due to overload and burn. After put into the well, the measurement of the motor and the ground insulation resistance value, not less than 100M. After the start, regular observation of voltage and current, and check the motor winding insulation is in line with the requirements of the provisions. If the temperature of the storage site is below the freezing point, the water in the pump chamber should be drained to prevent the water in the motor chamber from freezing and damaging the motor due to low temperature.

Setelah lapisan diikat erat dengan kawat tembaga halus, solder secara menyeluruh dan kuat, lalu pasir apa saja. gerinda di permukaan. Kemudian untuk ketiga sambungan tersebut, gunakan isolasi polyvester untuk membungkusnya secara setengah bertumpuk untuk tiga lavers. Lilitkan kedua ujung lapisan pembungkus rapat-rapat dengan benang nyion, kemudian gunakan cara setengah tumpuk untuk membungkus selotip sebanyak tiga lapis. Bungkus lapisan luar dengan pita insulasi bertekanan tinggi sebanyak tiga lapis. Terakhir, lipat ketiga helai menjadi satu dan bungkus berulang kali menjadi lima lapisan dengan pita bertekanan tinggi. Setiap lapisan harus terikat erat, dan sambungan antar lapisan harus rapat dan kokoh untuk mencegah air masuk dan merusak isolasi. Setelah dibungkus, rendam dalam air pada suhu kamar 20'c selama 12 jam, dan ukur ketahanan isolasi dengan meja pengocok. , yang tidak boleh kurang dari 100M Ω
Diagram proses pengkabelan kabel terlampir adalah sebagai berikut:
8. Gunakan multimeter untuk memeriksa apakah kabel tiga fasa tersambung dan apakah resistansi DC kira-kira seimbang.
9. Periksa apakah rangkaian dan kapasitas trafo kelebihan beban, lalu sambungkan sakelar proteksi kelebihan beban atau peralatan starter. Lihat Tabel 2 untuk model tertentu, laluTuangkan seember air ke dalam pompa air dari stopkontak pompa air untuk melumasi bantalan karet di pompa, lalu letakkan pompa listrik submersible dengan tegak dan stabil.Mulai (tidak lebih dari satu detik) dan periksa apakah arah kemudi sesuai dengan tanda kemudi. Jika tidak, tukar dua konektor kabel tiga fasa. Kemudian pasang filter dan bersiap untuk turun ke sumur. Jika digunakan pada acara-acara khusus (seperti parit, parit, sungai, kolam, kolam, dll.), pompa listrik harus diarde dengan baik.
(2) Peralatan dan perkakas instalasi:

7. Saat pompa air bekerja, keluaran air harus terus menerus dan merata, arus harus stabil (dalam kondisi kerja terukur, umumnya tidak lebih dari 10% arus terukur), dan tidak boleh ada getaran atau kebisingan. Jika terdapat kelainan, sebaiknya mesin dihentikan untuk mengetahui penyebabnya dan menghilangkannya.
8. Saat memasang, perhatikan pengaturan kabel ground motor (lihat Gambar 2). Jika pipa air berupa pipa baja, arahkan dari klem kepala sumur; bila pipa air berupa pipa plastik, arahkan dari tanda grounding pompa listrik.
- 1.After installing the submersible pump, recheck the insulation resistance and three-phase continuity switch, check whether there is any error in the connection between the instrument and the starting equipment.If there is no problem, you can start to test the machine. After starting, observe whether the indication reading of each instrument is correct.If the rated voltage and current specified on the nameplate are exceeded, please observe whether the pump has noise or vibration.If everything is normal, it can be put into operation. After the pump runs for the first time for four hours, the motor thermal insulation resistance should be closed and tested quickly. Its value should not be less than 0.5 megaohm. After the pump stops, it should be restarted after five minutes to prevent the water column in the pipeline from completely reversing, which will cause the motor to burn out due to excessive current.
- 2.After the pump is put into normal operation, in order to prolong its service life, it is necessary to check whether the supply voltage, working current and insulation resistance are normal regularly. If the following conditions are found, the machine should be stopped immediately to troubleshoot.
- 1.Under the rated working condition, the current exceeds 20%.
- 2.The dynamic water level drops to the water inlet section, resulting in intermittent water.
- 3.The submersible pump has severe vibration or noise.
- 4.The supply voltage is lower than 340 volts.
- 5.A fuse is burned out.
- 6.The water pipeline is damaged.
- 7.The motor's insulation resistance to the geothermal state is lower than 0.5 megaohm.
- 3.Unit disassembly:
- - Lepaskan pengikat kabel, lepaskan bagian pipa, dan lepaskan pelat kawat.
- - screw down the water bolt, put out the water in the motor chamber.
- - lepaskan filter, longgarkan sekrup tetap pada kopling untuk mengencangkan poros motor.
- 4.screw down the bolt connecting the water inlet section with the motor, and separate the pump from the motor (pay attention to the unit cushion when separating, to prevent the bending of the pump shaft)
- 5.the disassembly sequence of the pump is: (see figure 1) water inlet section, impeller, diversion shell, impeller...... check valve body, when removing the impeller, use special tools to loosen the conical sleeve of the fixed impeller first, and avoid bending and bruising the pump shaft in the process of disassembly.
- 6.the disassembly process of the motor is: (see figure 1) place the motor on the platform, and remove the nuts, base, shaft head locking nut, thrust plate, key, lower guide bearing seat and double head bolt from the bottom of the motor in turn, and then take out the rotor (pay attention not to damage the wire package) and finally remove the connecting section and upper guide bearing seat.
- 7.unit assembly: before assembly, the rust and dirt of the parts should be cleaned, and the mating surface and fasteners coated with sealant, and then assembled in the opposite order of disassembly (the motor shaft moves up and down after assembly for about one millimeter), after assembly, the coupling should be flexible, and then the filter screen test machine. Submersible pumps shall be taken out of the well for dismantling and maintenance according to Article 5 after a year of operation, or less than a year of operation but two years of diving time, and the worn parts shall be replaced.
1, keluarkan air di rongga motor (terutama di musim dingin untuk mencegah motor membeku), dan ikat kabel dengan baik.
2, simpan di ruangan dalam ruangan tanpa zat dan gas korosif, dengan suhu di bawah 40 °C.
3, penggunaan jangka panjang harus memperhatikan pencegahan karat pada pompa submersible.
