SLE 350 - Verification of Tightness of Joints and Inspection of Appliance; Checking of Capacity

Page 27 of 42
8.12 Verification of tightness of joints and inspection of appliance
8.12.1 Test of leakage:
• By disconnecting output hose from fast-on coupling marked OUT the
consumption of compressed air is stopped.
• Pressurize pressure tank (forced start-up of compressor can be done for
example by releasing of part of air via supplied device).
• Compressor must not be put into operation automatically for at least 10 min.
• If it comes to the drop out of pressure, use soapy water to find the leakage at
joint - firstly outside the case, then inside the case after its dismounting.
• Remove found leakage by tightening or re-sealing the joint.
8.12.2 Inspection of appliance:
• Check the condition of hangers of pump.
• Check the condition of filter. At regular operation condensate from filter (14) is
exuded automatically. Verify the function of automatic sludging by comparing
the level of condensate in a vessel with scale line indicating maximal level. The
level of condensate must not be over the scale line. In the case of incorrect
function it is necessary to replace faulty parts.
• Release the condensed liquid from the water trap of the pressure regulator.
• Check the condition of pump itself:
- impurities in crank box
- freedom at crank shaft
• Replace faulty parts.
8.13 Checking of Capacity
Before checking of capacity it is necessary to switch off the
compressor, let pressure air out of air tank and unlink
output hose from fitting OUT. Next switch on the
compressor and measure (record) the time before points
start - stop. The capacity of compressor is satisfied when
the recorded time is not higher than 45 s for type SLE350,
and 30 s for type SLE500.
