Problems solved by technology

[0004] During the use of the above-mentioned deep well pump, the deep well pump is generally immersed underwater. During this process, the pressure on the motor will gradually increase. At this time, the water outside the deep well pump will gradually enter the inside of the motor, making Water will come into contact with the stator coils inside the motor, easily causing damage to the motor

Embodiment 1

[0044] see figure 1 , figure 2 , a deep well pump with a high-efficiency waterproof motor, including a pump body 1, a motor 2 fixedly connected to the bottom of the pump body 1, the motor 2 includes a barrel 21, a rotor 24 and a stator coil 25 are arranged in the barrel 21, and the stator coil The outer sidewall of 25 is fixedly connected on the inner sidewall of machine barrel 21, and the middle part of rotor 24 along the length direction is pierced with output shaft 26, and the two ends of machine barrel 21 are respectively provided with upper bearing seat 22, lower bearing seat 23, output shaft One end of 26 is connected to the lower bearing seat 23, and the other end passes through the upper bearing seat 22 and is connected to the pump body 1.

[0045] see figure 2 , image 3 A cylindrical shielding sleeve 3 is provided between the outer wall of the rotor 24 and the stator coil 25. The shielding sleeve 3 is made of stainless steel for isolating the rotor 24 and the st...

Embodiment 2

[0052] A deep well pump production process with a high-efficiency waterproof motor, comprising the following steps:

[0053] Step 1: first install the stator coil 25 into the barrel 21, and put the upper bearing seat 22 into the end of the barrel 21 close to the pump body 1, and then put the shielding sleeve 3 into the barrel 21 so that the shielding sleeve 3 fits On the stator coil 25, put the rotor 24 into the shielding sleeve 3 so that the output shaft 26 protrudes from the end of the upper bearing seat 22, and then put the capacitor 5 on the outside of the shielding sleeve 3 at the bottom of the barrel 21;

[0054] Step 2: The epoxy resin 4 can be poured three times through the pouring hole 6 to the stator coil 25. When pouring for the first time, first vacuum the inside of the machine barrel 21 for the first time, and then fill the ring that needs to be filled for the first time. The epoxy resin 4 is heated to 70-80° C., and the heating time is 15-25 minutes. After the ep...

Abstract

The invention discloses a deep well pump with an efficient waterproof motor and a production technology of the deep well pump with the efficient waterproof motor. The deep well pump with the efficientwaterproof motor is characterized by comprising a pump body and a motor, wherein the motor comprises a motor barrel, the motor barrel is provided with an upper bearing seat, a lower bearing seat, a rotor and a stator coil, an output shaft is arranged in the middle of the rotor in a penetrating manner, the rotor is sleeved with a shielding sleeve, the two ends of the shielding sleeve are fixedly connected with the upper bearing seat and the lower bearing seat, epoxy resin is poured between the shielding sleeve and the stator coil, and the stator coil is wrapped inside the epoxy resin. The production technology of the deep well pump comprises the steps that after the upper bearing seat, the stator coil, the shielding sleeve, the rotor and a capacitor are installed, the epoxy resin is heatedat different times for different times and poured into the motor barrel three times so as to wrap the stator coil. The epoxy resin has the characteristics of high anti-leakage performance and high compactness, so that water entering the motor can be isolated from the stator coil beneficially, and it is effectively avoided that the water makes contact with the stator coil; and in this way, the waterproof effect in the motor is improved, and motor damage is reduced.

Description

technical field [0001] The invention relates to the field of water pumps, in particular to a deep well pump with a high-efficiency waterproof motor and a production process thereof. Background technique [0002] A deep well pump is a machine that goes deep into a wellbore to extract water. It is a pump that is immersed in groundwater wells for suction and water delivery. It is widely used in mine rescue, construction drainage, agricultural irrigation, industrial water circulation, hot spring water, drinking water supply for urban and rural residents, etc., and even emergency rescue and disaster relief. extracted water, etc. [0003] Existing deep well pumps, such as a Chinese invention patent whose notification number is CN206111595U, disclose an oil-immersed deep well pump, including a motor, a water inlet section, a pump body, and a water outlet section. The motor includes a machine barrel, and the two ends of the machine barrel are The upper end cover and the lower end ...
