Preferably, holding tank is offered on the shell of the plug hole both sides, the capacitance further includes being arranged in series
The quantity of small capacitances in the holding tank, the small capacitances is 9-11.
Through the above technical solutions, since capacitance plays a decisive role to the water speed etc. that goes out of deep well pump, by by capacitance
It is divided into 9-11 small capacitances and is installed in series in holding tank, maximizing improves the working efficiency of deep well pump, and each small electricity
Hold the temperature all same that can bear, if deep well pump in the higher underwater work of the temperature such as hot spring, after multiple small capacitances combinations
The temperature higher that can bear.
Preferably, graphite bearing is equipped in the step, the graphite bearing is sheathed on output shaft.
Through the above technical solutions, when output shaft is during rotation work, by the way that graphite bearing is arranged, compared to common
Bearing, the endurance of step can be effectively improved, be conducive to extend the service life of motor；In addition graphite bearing had been used both
It is suitable for higher motor speed, meets the requirement of present frequency conversion rotating speed, the rotating speed of different frequency can also be adapted to, it is maximum suitable
Rotating speed is answered to can reach 12000/r.
Preferably, it is arranged with sliding block on the lateral wall of the step, abaculus, institute have been provided projectingly on the sliding block
State output shaft and be arranged with mounting ring on the lateral wall of the graphite bearing, offered in the mounting ring with the abaculus to
Chimeric caulking groove.
Through the above technical solutions, when output shaft is during rotation work, by abaculus and caulking groove it is mutual it is chimeric with
Limit the rotation of mounting ring so that the upper surface of graphite bearing is tightly attached in the lower surface of mounting ring, to be formed to ensure that rotor rotates
Active force can act in mounting ring, and then the active force to graphite bearing can be reduced, further increase graphite bearing
Service life.
In view of the deficienciess of the prior art, it is another object of the present invention to provide one kind carrying high-effective water-proof motor
Deep well pump production technology, have improve deep well pump waterproof effect advantage.

120 DEG C, heating time is 40~60 minutes, and after epoxy resin further softens after injection machine barrel, standing 2.5~3 hours makes ring
Oxygen resin solidification；
Step 4：Third time vacuum processing is carried out to inside machine barrel later, the new epoxy resin of third time is then heated to 140
~160 DEG C, heating time is 1~2 hour, and after epoxy resin melts injection machine barrel, standing 3.5~4.5 hours makes epoxy resin
Solidification；
Step 5：Step is packed into the lower section of capacitance, then covers bottom cover closing and fixes.
Through the above technical solutions, by being vacuum-treated to inside machine barrel before injecting epoxy resin each time,
So that the epoxy resin under soft state is acted on, so that epoxy resin during entering in machine barrel by external pressure
It can be rapidly introduced into machine barrel, and can have gap between the copper wire of stator coil, epoxy resin in a compressed state can
It progresses into gap, so that stator coil can be wrapped up adequately；It is injected in three times additionally by by epoxy resin
Into machine barrel, and the time heated every time is gradually increased with temperature so that the softening degree of epoxy resin can be gradually increased, together
When in third time epoxy resin is heated to molten condition, be successively injected into machine barrel again in this way, with gradually by stator coil packet
It is rolled in epoxy resin, after the epoxy resin injection especially under third time molten condition so that after preceding injection twice in machine barrel
Remaining gap existing for portion is further wrapped up, and then can effectively avoid water by the water segregation of entrance outside stator coil
Contact with stator coil is conducive to improve the waterproof effect inside motor.
In conclusion the present invention having the beneficial effect that in contrast to the prior art：
1, by being filled with epoxy resin that stator coil is fully wrapped around, to give full play to, epoxy resin leakage resistance is strong, density
High and strong adhesive ability feature, the water segregation for being conducive to enter effectively avoid water and stator coil outside stator coil
Contact, and then improve motor inside waterproof effect, reduce motor damage；
2, by the way that capacitance to be built in the bottom of motor, the use of cable can be effectively reduced, be conducive to it is cost-effective, while by
In the protection of external barrel, the probability that capacitance is destroyed can be reduced；
3, by using graphite bearing, the endurance of step can be effectively improved, is conducive to extend the service life of motor.
