Electrode Boiler
POWER UNIT STARTUP
1. To properly perform the dual function of lubrication and transmission of
power, we recommend the use of a good quality SAE 10 Grade Hydraulic Oil
for systems having an operating temperature range from 0 deg F minimum to
160 deg F maximum, or an SAE 20 Grade Hydraulic Oil for 32 deg F Minimum
to 200 deg F maximum temperature range. Operation at fluid temperature
below 160 deg F is recommended to obtain maximum unit and fluid life.
2. Connect the motor to the proper electrical source, checking the motor
nameplate for proper wiring of dual voltage motors. Jog the motor to check
rotation. Poly-phase motors are bi-directional and proper rotation can be
established by reversing any two phases.
Simultaneously energizing both solenoids on double solenoid valves will cause coil burnout.
3. System pressure should be set as low as possible to prevent unnecessary
fluid heating; on some applications this setting may be from 600 to 1,000 psi
as needed to overcome dynamic pressure drop or to achieve proper
acceleration and lift load control components.
4. Pump noise and 'crackle' is most often caused by air entering the pump
suction. The tightening of suction fittings will usually eliminate such problems.
If pump fails to prime, vent pump discharge to atmosphere to establish fluid
flow.
5. The fluid level should be maintained so that fluid is always visible in the
sight gauge.
6. After the first few hours of operation, any foreign material from the system
plumbing will be flushed to the reservoir. It is good practice to drain and
replace the initial filling, and to clean the reservoir and suction strainer.
7. For most industrial applications, an operating temperature of 150 deg F is
considered maximum. At higher temperatures difficulty is often experienced in
maintaining reliable and consistent hydraulic control, component service life
is reduced, hydraulic fluid deteriorates, and a potential danger to operating
personnel is created.
8. At least once a year or every 4,000 operating hours the reservoir, suction
strainer, and air vent filter should be cleaned. At this time, check the entire
system for possible future difficulties. Some application or environmental
conditions may dictate such maintenance be performed more frequently.
