Instruction manual for Water-cooled Air Compressor HV2/210 - 4 -
3.3. Starting up
Before initial starting up and after long periods out of use, carry out he following operations:
A. Check the oil level.
B. Check that the quality of the oil has not been impaired by water or other foreign matter.
C. Check compressor valves and lubricate the cylinder with oil.
D. Turn over the compressor by hand, with the suction valve relieved by means of the manual valve opener.
E. Check cooling water circulation.
F. Check that the air line cock between the compressor and the air reservoir is open.
G. Open the manual drain cocks on the water trap.
H. Start the compressor.
I. If everyhing is operating normally, close the drain cocks and set the valve opener in the operating position.
Allow the compressor to run for a few minutes before loading it to maximum working pressure.
3.4. Operation
During normal operation, pressures and temperatures should be as shown in Table T.2. Some of the values,
which are directly affected by local conditions, may deviate slightly from the figures in the table.
Operation of the compressor is normally monitored by the automatic features of the starting equipment, e.g.
pressure switch monitoring of lube oil pressure and thermostat monitoring of cooling water temperature.
However, additional regular checking of operation and automatic functions is recommended.
Some water form the compressed air will always condence in the system. The compressor is fitted with drain
cocks after the HP and LP coolers. If these are not automatically controlled, they must be drained
regularly by
hand. Also, the oil and water traps should be regularly drained by hand, unless this function is performed by an
automatic draining system.
Special water traps to collect condensate after the LP cooler can be supplied to order, by the manufacturer.
3.5. Stopping
Stopping the compressor manually for short periods:
A. Operate the manual valve opener to relieve the LP suction valve.
B. Open the water trap drain cocks.
C. Stop the compressor.
If the compressor is to be shut down for a long period, e.g. when a ship is to be laid up, the procedure is as
follows:
AA. Lubricate compressor valves, non-return valves, cylinder walls and exposed crankshaft surfaces with
corrosin-inhibiting oil, suitable for the envisaged period of shutdown.
BB. If there is any risk of frost, drain the cooling water from the compressor.
CC. Drain off old oil, clean the sump and refill with new oil.
DD. Set the manual valve opener in the horizontal position to relieve the load on the suction valve.
EE. Turn over the compressor manually once a month.
FF. The starter cabinet and other electrical equipment should also be protected from damage by corrosion.
