Working principle of the utility model is:
Test-run a machine high-precision fluid-flywheel clutch test-run a machine, scoop tube 3 0% position (pay attention to it is stable after add oil to " upper
Line " is not inserted into liquid strap room 7), 50% position (i.e. insertion 7 middle position of liquid strap room), 100% position (i.e. insertion liquid
7 bottom of strap room) under be separately operable 1~2 hour, import/export oil temperature should be maintained at 40~60 DEG C or so (by cooler water valve
Aperture regulation), normal rear scoop tube returns at low level 0%, shuts down.
Normal use (1) starting
Before each high-precision fluid-flywheel clutch starting, it is necessary to check oil ga(u)ge oil level whether 2/3 or more；Check high-precision liquid
Whether couple clutch oil pipe line connects correct with instrument electric wiring；High-precision fluid-flywheel clutch fuel tank oil temperature is checked, if oily
Temperature is lower than 5 DEG C using electric heater heating (such as with N46 oil, should be heated to 10 DEG C or more preferably).
(2) it runs
It, can be manual by external control device (Electric Actuator, electric operator) when high-precision fluid-flywheel clutch operates
Or motorized adjustment coupling device scoop tube position, any output revolving speed for changing liquid idol.Note: if motor speed is (4 grades or more higher
Motor) and high-precision fluid-flywheel clutch output shaft (scoop tube 3 is closely located to or at 0%, may when working under the very slow-speed of revolution
The noise for working normally and not occurred when operating is heard, this is because scoop tube mouth and pump impeller outer rim outage meet and generate
Caused by " steam whistle effect ", this is normal phenomenon, not liquid idol failure.
(3) it limits
It is unsuitable too low that high-precision fluid-flywheel clutch exports revolving speed, generally with M ∝ n2When the centrifugation class loaded matching of characteristic, most
Low output revolving speed generally should be higher than that 1/5 rated speed (characteristic range of instability is under 1/5)；High-precision execution mechanism 9 is according to normally
It is worth or pre-sets control scoop tube 3 and be inserted into depth in liquid strap room 7, when the bosom of scoop tube insertion liquid strap room, in circulation circle
Oil mass is minimum, and pump impeller and secondary speed deviation are big, and output revolving speed is minimum;When the most shallow place of scoop tube insertion liquid strap room, circulation
Oil mass is maximum in circle, and pump impeller and secondary speed deviation are small, and output revolving speed is maximum.
