WARNING
Laying cables at temperatures below zero degrees
Damage to the cables!
▷ Observe the minimum permissible temperature at the cable surface of -25 °C for
moving cables.
▷ Observe the minimum permissible temperature at the cable surface of -40 °C for
stationary cables.
NOTE
Do not expose power cables to direct sunlight.
NOTE
A separate name plate is included in KSB's scope of supply.
This name plate must be attached in a clearly visible position outside the place of
installation, e.g. at the control panel, pipeline or mounting bracket.
NOTE
The motor lead is selected for submerged operation and must be completely
submerged, including the cable connector.
See order documentation for any other use!
5.2 Preparing the installation
5.2.1 Checking the installation conditions
Prior to starting with the installation, check compliance with the particular
framework conditions required for a trouble-free operation of the submersible
borehole pump. To do so, verify the order data and/or delivery data against the
constructional plans, the operating conditions and the operating limits of the pump
set.
1.
Has this pump set been ordered for the required installation position?(⇨ Section
5.2.2 Page 22)
2. Does the material variant of the pump set match the installation conditions?
3. Can the required flow velocity past the motor be guaranteed?
4. Is the required minimum submergence met during operation? (⇨ Section 6.2.3.1
Page 41)
5. Is the sand content of the fluid to be handled below the specified maximum?(⇨
Section 6.2.3.2 Page 42)
6. Is the temperature of the fluid to be handled below the specified maximum?
7. If fluids liable to form deposits are handled, is temperature monitoring provided?
8. Will the motor lead and the cable connector be completely submerged?
General information on the system design
Select a pump set suspension arrangement whose design and dimensions allow for all
static and dynamic forces to be absorbed. Tightly fasten the supporting clamps or
flanges to the well head so that they cannot move or lift off the well head.
System-induced vibrations must not be transmitted to the pump set. The system must
be designed in such a way that vibrations are not amplified. Abrupt pressure
equalisation processes (pressure surges), in particular, present a hazard for the pump
set. Take suitable precautions (e.g. fit expansion joints, air vessels).
