6. Explosion—proof main point
6.1 The series electric motor is explosion-proof motor , the outer covering of the motor should
not damage or distorted causing tothe failing to explosion-proof , and the other explosive gas
should not explode by the fire through the junction plane for the explosion-proof after the inner
gas explode . For:
a. The parts of the motor covering, example the end cover, bearing inside cap, terminal
7

box lid, terminal box base, should pass the hydraulic pressure lest, with the pressure is
1.0MPa and lasted 1 minute.
b. The length of the junction plane for explosion-proof, the gap, the surface roughness, the
electric gas between the exposed conductors, between the exposed conductor and the
metal covering ,and the creeping distance ,please look at the drawing No.1、2.
c. There are spring washers under the bolts connect the outer covering parts, which can
prevent the bolts loosing.
d. The stator housing, end cover, the inner bearing cap, the terminal box, the terminal
block, the shaft, and the oil seal is the parts for the explosion–proof.
6.2 Under the worst status, the temperature of the surface of the motor should not surpass
+135℃. The factory should use the motor according to table 4.

Type of explosive admixture T1 T2 T3 T4
Allowed temp rising of the surface (℃） 450 300 200 135
7. Install and use
7.1 Preparative before to install
7.1.1. The wrapping is good or not should be checked up before it open.
7.1.2. The dust and the anticorrosive things should be eliminated the motor are installed.
7.1.3. The steps should be done before install the motor.
a. There are a mark and a card number of explosion-proof with the motor. Please check
if it fulfillsthe demand of the using environment.
b. The bolts connecting the outer covering parts should not loose.
c. The parts of outer covering should have not crackled or disfigurements.
d. The grease must be enough, and the tools for grease are good.
e. The insulation resistance should not be lower than 0.38 MΩwhen the rated voltage is
380V and should not be lower than 0.66MΩwhen the rated voltage is 660V.
7.2 The electric motor uses the elastic shaft coupling transmission; the center of the motor
8

shaft and center of the drive machine must maintain consistently otherwise can cause the
bearing damage.
7.3 The connection between the motor and power.
7.3.1. The outer diameter of the power cable must tally with seal, which material is rubber
XH-21. The difference between both outer diameters should not be bigger than 1mm, when
the cable gland is fixed, there should be no clearance between the cables and between the
seal and terminal box otherwise will lose the explosion-proof performance.
7.3.2. The cable should be fixed between two bows gaskets, the attention core burr is
prominent, and should be fixed closely by blocks and the gaskets.
7.3.3. The motor with six terminal bolts can be used with two voltages by 2 different
connections. When just 1 cable gland is used, another metal washer, which thickness is 2mm,
should not be removed. Otherwise the explosion-proof performance will be losing.
7.3.4. The order of the 3 phase of the power should be same as the motor cable. The
rotation should be clockwise.

Phase sequence A B C
Head U1 V1 W1
Tail U2 V2 W2
7.3.5. Other earth bolt should connect with the ground.
7.3.6. After connected correctly, the motor should run with no load, if there is no problem, it
can run with load.
7.3.7. Terminal-box Seal Dimensions (MM)

8. Maintains
8.1. The motor should be clear and check termly. There should no dust in the surface,
spraying to the motor with the water cock is not allowed.
8.2. The temperature of the bearing should not surpass +95℃, the bearings must be
degreased in 2500 hours at least, change the lubrication if it is not good. Before changing it,
the bearing cap, the lubrication cup and wasted lubrication must be cleaned with gasoline, the
quantity should reach the 1/2 of the bearing house for 2 poles, 2/3 for 4 poles.

8.3. The explosion-proof surface should be paid attention when the motor Disassembles and
assembled, there is no outer bearing cap in the motor frame No. from 80 to 160. the bearings
was fixed by the bearing ring. Disassembling the electric motor, we should disassemble the V
bearing ring, then the front end-shield, the fan cover, the bolt of the hinder end-shield, remove
the hinder end-shield from the rotor, assembling the motor, we should do in reverse.
8.4. Motor affected with damp, must undertake the drying process, the drying furnace or the
short circuit current method. In the process of drying, winding temperature rise should be
increased gradually, and not more than 155 ℃. Short circuit current method when dry, the
motor is under the short circuit state, the input current tothe 0.6～0.8 times of the rated
current for appropriate, serious damp motor is not easy to use DC electric drying, so as to
avoid electrolysis.
8.5. Replacing the winding, the technical data should be got from the company, if not, the
motor always work not so well, even burn out.
