Explosion-Proof Motor; Start-Up; General; Motor With Pump - schmalenberger 27217-A Manual De Instrucciones

The motor must be connected in accordance
with the accompanying circuit diagram. Screw
down the cable connections and the ground
wires tightly.
If possible use wire end ferrules without
insulating material collars in accordance with
DIN 46228, Part 1, material E-Cu.

Start-up

5.1

General

After making the connections and before starting
up the motor make sure that the direction of
rotation is correct.
Follow the specifications in the operating
instructions for the centrifugal pump, section
2.3.4, topic: Checking direction of rotation.
5.2

Motor with pump

The instructions
instructions for the centrifugal pump, section 3.1,
topic: First-time start-up apply to the start-up of
the motor together with the centrifugal pump.
During start-up be certain that:
• the motor is running properly (speed
variations, development of loud sounds,
etc.),
• all of the motor protection devices are set
to the rated current of the motor,
• the heating of the motor, especially at the
bearings, does not exceed the maximum
limit.

Inspection and servicing

6.1 Inspection & service intervals
The pump drives from the Schmalenberger
company are largely
Depending on where they are used and the
operating circumstances, however, monitoring is
needed to maintain performance and prevent
damage.
It is expedient to inspect the drive together with
the centrifugal pump. Also see the operating
instructions for the centrifugal pump, section 4.1,
topic: Servicing & inspection.
The following checks and tasks should be
performed at least monthly:
• Check heating of motor and bearings
• Remove soil from the cooling fins
• Functional check of the safety equipment

Motor bearings

The service life of the motor bearings is
significantly influenced
conditions. The rule of thumb is:
every 10,000 hours of operation
- replace roller bearings
- replace shaft seals
- clean cooling air channels
- correct (renew) corrosion protection.
For motors starting with frame size 160 with AS-
flanged bearing end housing ø 300 (applies to
the single-race angular-contact ball bearings
7212 and 7310) the rule is:
every 4,000 hours of operation
- Re-grease the roller bearings in the
AS flange with 15 g high-temperature
grease (-40 - 180 °C, for example Klüber
Asonic HQ72-102).
Re-grease using the grease fitting 636.
