6, after the pump down the well, the measurement of the motor to the ground insulation resistance should not be less than 100M, after the start to observe the voltage and current, check the motor winding insulation, whether in line with the requirements; pump storage location temperature if less than freezing point, should be dry the motor cavity water, prevent the motor cavity water ice damage caused by low temperature.

 Structure brief introduction: the pump part is mainly composed of pump shaft, impeller, diversion shell, rubber bearing, check valve body (optional parts) and other components. The motor part is mainly composed of base, pressure regulating film, thrust bearing, thrust plate, lower guide bearing seat, stator, rotor, upper guide bearing seat, sand ring, water inlet section, and cable.

ʻO nā hiʻohiʻona nui o ka huahana:

1.The motor is a water-loaded wet submersible three-phase asynchronous motor,and the motor cavity is filled with clean water for cooling the motor and lubricating the bearing.The regulating diaphragm at the bottom of the motor is used to adjust the expansion and contraction pressure difference inside and outside the body caused by the temperature rise of the motor.
2.In order to prevent the sand particles in the well water from entering the motor,two oil seals are installed at the extension end of the motor shaft,and the sand ring is installed to form a sand prevention structure.
3.In order to prevent the pump shaft from jumping when starting,the pump shaft is connected with the motor shaft through a coupling,and the thrust bearing is installed at the bottom of the motor.
4.The lubrication of the motor and the pump bearing is water lubrication.
5.The stator winding of the motor adopts high-quality submersible motor winding wire,with excellent insulation performance.
6.The pump is designed by computer CAD,with simple structure and excellent technical performance.

A laila, no nā hui ʻekolu, e hoʻohana i ka lipine insulation polyvester e hoʻopili iā lākou ma ke ʻano semi hoʻopaʻa ʻia no ʻekolu ʻauʻau. E wīwī i nā ʻaoʻao ʻelua o ka papa wrapping a paʻa me ke kaula nyion, a laila e hoʻohana i ke ʻano semi-stacked e ʻōwili i ka lipine no ʻekolu papa. E uhi i ka outellayer me ke kiʻekiʻe-press insulation tape no ʻekolu papa. ʻO ka hope, e pelu i nā kaula ʻekolu a hoʻopaʻa pinepine iā lākou no nā papa ʻelima me ka lipine kaomi kiʻekiʻe. Pono e hoʻopaʻa paʻa ʻia kēlā me kēia papa, a pono e paʻa a paʻa nā hui interlayer e pale aku i ka wai mai ke komo ʻana a me ka hōʻino ʻana i ka insulation, Ma hope o ke kāwili ʻana, e hoʻoinu i ka wai i ka lumi wela o 20 'c no 12 mau hola, a e ana i ke kūpaʻa insulation me kahi papa haʻalulu. , ʻaʻole pono e emi ma lalo o 100M Ω

ʻO ke kiʻikuhi kaʻina hana uwila i hoʻopili ʻia penei:

8. E hoʻohana i ka multimeter no ka nānā ʻana inā pili ʻia nā uea ʻekolu ʻāpana a inā ʻaʻole kaulike ke kūpaʻa DC.
9. E nānā inā ua hoʻonui ʻia ka mana kaapuni a me ka mea hoʻololi, a laila hoʻohui i ke kī hoʻomalu overload a i ʻole nā ​​mea hoʻomaka. E nānā i ka Papa 2 no nā hi'ohi'ona kiko'ī, a laila, e ninini i ka bākeke wai i loko o ka pā wai mai ka puka wai e ho'oma'ama'a i ka pahu pahu i loko o ka pama, a laila e kau i ka pauma uwila i lalo i luna a pa'a. a e nānā inā pili ka hoʻokele me ka hōʻailona hoʻokele. Inā ʻaʻole, e hoʻololi i nā mea hoʻohui ʻelua o ke kaula ʻekolu. Inā hoʻohana ʻia i nā hanana kūikawā (e like me nā ʻauwai, nā ʻauwai, nā muliwai, nā loko, nā loko, a me nā mea ʻē aʻe), pono e hoʻopaʻa ʻia ka paila uila.

(2) Mea hoʻokomo a me nā mea hana:
1. Hoʻokahi mau kaulahao hāpai no ʻelua mau tona.
2. ʻO kahi tripod me ke kiʻekiʻe kū i lalo o ʻehā mau mika.
3. ʻElua kaula kau (wire ropes) hiki ke kaumaha i ke kaumaha ma mua o hoʻokahi tona (hiki ke halihali i ke kaumaha o ka pahu wai piha).

3. ʻO nā pumps me ke poʻo i ʻoi aku ma mua o 30 mika e hoʻohana i nā paipu kila, a penei ka hoʻonohonoho ʻana:
①E hoʻohana i kahi pipili no ka hoʻopaʻa ʻana i ka ʻaoʻao o luna o ka ʻaoʻao o ka pauma wai (ua hoʻopili ʻia ke kaʻa a me ka pauma wai i kēia manawa), e hoʻokiʻekiʻe me ke kaulahao e kau ana, a nakinaki mālie i loko o ka luawai a kau i ka paʻi ma ke poʻo punawai a wehe i ke kaulahao. kaulahao e kau ana.
② E hoʻohana i nā paipu ʻē aʻe e hoʻopaʻa i ka paipu, e hoʻokiʻekiʻe me ke kaulahao e kau ana ma kahi mamao o 15 knm mai ka lehelehe, a e hoʻohaʻahaʻa mālie. Ma waena o ka flange paipu a me ka flange pump E hoʻopaʻa i ka pā hao a hoʻopaʻa i ka paipu a paʻa pono me nā bolts, nati a me nā mea holoi puna.
③ E hoʻokiʻekiʻe iki i ka pauma hoʻohaʻahaʻa, e wehe i ke kaula ma ka ʻaoʻao o luna o ka pā wai, e hoʻopaʻa paʻa i ke kaula i ka paipu wai me ka lipine plastik, a nakinaki mālie i lalo a kau ʻia ka paʻi ma ka luawai.
④E hoʻohana i ke ʻano like e hoʻopaʻa ai i nā paipu wai a pau i loko o ka pūnāwai.
⑤Ma hope o ka hoʻopili ʻia ʻana o ke kaula alakaʻi i waho i ka hoʻololi mana, ua hoʻopili ʻia i ka lako mana ʻekolu.

(4) Nā mea e nānā ai i ka wā e hoʻokomo ai:
1. Inā ʻike ʻia kahi mea hoʻopuʻi i ka wā o ka pahū ʻana, e hoʻohuli a huki paha i ka paipu wai no ka lanakila ʻana i ke kiko pahu. Inā ʻaʻole e holo nā ʻano hana like ʻole, e ʻoluʻolu, mai hoʻoikaika i ka pamu i lalo e pale aku i ka pōʻino o ka pauma uila a me ka luawai.
2. I ka wā o ka hoʻokomo ʻana, pono e kau ʻia kahi pā hao ma ka ʻaoʻao o kēlā me kēia paipu a paʻa pono.
3. Ke hoʻohaʻahaʻa ʻia ka paila wai i loko o ka pūnāwai, pono e hoʻokomo ʻia i waenakonu o ka paipu pūnāwai i mea e pale ai i ka holo ʻana o ka pamu i ka paia o ka pūnāwai no ka manawa lōʻihi, e hoʻonāwaliwali ai ka pamu a e kahili a wela ke kaʻa. .
4. E hoʻoholo i ka hohonu o ka paila wai a hiki i lalo o ka luawai e like me ke kahe ʻana o ke one a me ka lepo o ka luawai. Mai kanu i ka pamu i ka lepo. ʻO ka mamao mai ka pā wai a hiki i lalo o ka pūnāwai ʻaʻole i emi iho ma mua o 3 mika (e nānā i ke Kiʻi 2).
5. ʻAʻole emi ka hohonu o ke komo ʻana o ka wai ma lalo o 1-1.5 mika mai ke kiʻekiʻe o ka wai ikaika a hiki i ka node inlet wai (e nānā i ke Kiʻi 2). Inā ʻaʻole, hiki ke pohō maʻalahi nā bearings pump wai.
6. ʻAʻole hiki ke haʻahaʻa loa ka hāpai ʻana o ka paila wai. A i ʻole, pono e hoʻokomo ʻia kahi valve puka ma luna o ka pipeline wai punawai e hoʻomalu i ke kahe ʻana o ka paila ma ka helu kahe i helu ʻia e pale ai i ka hoʻonui ʻia ʻana o ke kaʻa a puhi ʻia ma muli o nā kahe kahe nui.
7. I ka holo ana o ka pauma wai, pono e hoomau ka puka ana o ka wai a me ke ano, pono ke kupaa (ma lalo o na kulana hana i heluia, ma ke ano, aole oi aku mamua o 10% o ka manawa i heluia), a aole e haalulu a walawala. Inā loaʻa kekahi mea ʻino, pono ke kāpae ʻia ka mīkini e ʻike i ke kumu a hoʻopau.

• (1)After the submersible pump is installed, check the insulation resistance and three-phase conduction from the switch again, check whether the instrument and the connection of the start equipment are wrong, if there is no problem, the trial machine can be started, and observe whether the indicator readings of the instrument exceed the rated voltage and current specified on the nameplate after the start, and observe whether the pump has noise and vibration phenomenon, and put into operation if everything is normal.
• (2)After the first operation of the pump for four hours, the motor should be shut down to test the thermal insulation resistance quickly, and its value should not be less than 0.5 megaohm.
• (3)After the pump is shut down, it should be started after five minutes to prevent the water column in the pipe from being completely reflowed and causing excessive motor current and burnout.
• (4)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 pump should be shut down immediately to troubleshoot.
•  
• 1 In the rated condition, the current exceeds 20%.
• 2 Ke hāʻule nei ka pae wai ikaika i ka ʻāpana komo wai, e hoʻoulu ai i ka wai.
