Страница: 4 / 24

Cooling
CAUTION
Operating the motor without water cooling will destroy the motor.
Water must be neutral and clean. It must fulfill the following
conditions :
Temperature of water :
10-15°C at inlet
Quantity of cooling water : 4 l/min.
To ensure the flow rate regulation of the cooling water, we
recommend to fit a regulating valve at the cooling water inlet.
The Roots WY 4500 C has cooling systems in both cylinder covers
(cooling coils). These cooling systems are separated from each other.
A recirculating water-cooling system into the outlet flange enables a
stable temperature of the oil and the bearings.
Cooling water connection:
The cooling water connection can be made with flexible hoses or water
pipes (Connection: 1/4"). The water outlet must be without pressure.
Initial filling-up with cooling water:
- Remove the safety caps from the connections. Connect up the two
hoses at the water inlet.
- Fill in water until water flows out at the outlet.
- Connect up the two hoses at the water outlet.
On/ Off switch
The vacuum pump comes without on/ off switch. The control of the
vacuum pump must be provided in the course of the installation.
Safety
Intended use
DEFINITION : For the purpose of these instructions, “handling” the
vacuum pump means the transport, storage, installation,
commissioning, influence on operating conditions, maintenance,
troubleshooting and overhaul of the vacuum pump.
The vacuum pump is intended for industrial use. It must be handled by
qualified personnel only.
The different applications for use and operational limits of the
vacuum pump as laid out in the “Product Description” and the
“Installation Prerequisites” of the vacuum pump must be observed
both by the manufacturer of the machinery into which the vacuum
pump is to be incorporated and by the end user.
The maintenance instructions must be observed.
Prior to handling the vacuum pump these operating instructions must
be read and understood. If anything remains to be clarified please
contact your Busch representative!
Safety notes
The vacuum pump has been designed and manufactured in accordance
with the latest technical and safety standards. Nevertheless, residual
risks may remain. These operating instructions and the pump itself
inform about potential hazards where appropriate. Safety instructions
can be detected through the keywords, DANGER, WARNING and
CAUTION as follows:
DANGER
Disregard of this safety instruction will always lead to accidents
with fatal or serious injuries.
WARNING
Disregard of this safety instruction may lead to accidents with fatal
or serious injuries.
CAUTION
Disregard of this safety instruction may lead to accidents with minor
injuries or property damage.
Sound Emissions
Refer to the table “Technical Properties” for the permissible sound
levels in free field conditions according to EN ISO 2151.
CAUTION
The vacuum pump emits sounds of high intensity.
Risk of hearing damage!
Users spending a longer period of time in the vicinity of a
non-insulated vacuum pump must wear suitable hearing protection.
Transport
Roots vacuum pumps undergo a rigorous operating test in the factory
and are packed carefully to avoid transport damage.
The inlet and outlet flange are sealed with plugs so that no dirt can
enter the pump during transport. These covers must be removed
before connecting up the pump.
Please check packaging for transport damage on delivery.
The pump can be lifted from the packaging with suitable lifting gear
using the lifting brackets on the pump.
The packaging materials must be disposed of in accordance with
applicable environmental protection regulations, or re-used.
These operating instructions are part of the delivery packaging
consignment.
Pumps are generally shipped without oil.
Operating the vacuum pump without oil will destroy the pump!
Transport in Packaging
Packed on a pallet the vacuum pump can be transported with a forklift.
Transport without packaging
In case the vacuum pump is bolted to a pallet or a base plate :
u Remove the fixing bolts between the vacuum pump and the
pallet/ base plate
CAUTION
Do not walk, work or stand under suspended loads.
CAUTION
Please check out the weight of the vacuum pump before lifting it up
(see "Technical Data").
Use adequate lifting gear for this.
l Attach lifting gear to a crane hook equipped with a safety latch
l Lift the vacuum pump with a crane hook
In case the vacuum pump was bolted to a pallet:
l Remove the stud bolts from the rubber feet
