Heat transfer oil top-up
Thread Content
The low-level tank is used to refill the high-level tank with heat transfer oil (not for the first time); at what liquid level in the high-level tank should the filling be stopped? When the low-level tank refills the high-level tank with oil, does the circulation system of the high-level tank need to have a pump running?
Automatic overflow of the high-level tank or disappearance of the alarm signal
First, top up the liquid level to just below the alarm threshold of the high-level tank, then stop adding fluid. Start the pump to circulate and exhaust air from the system; after exhaustion, the liquid level usually drops, at which point add a little more fluid as appropriate.
How long does it take to exhaust the circulating pump, and then should we observe the fluid replenishment situation?
Based on the oil return time in a heat transfer oil system, this time is calculated by dividing the total amount of oil by the pump’s flow rate; the actual return time can be slightly longer than this value
May I ask, at what temperature should the system be maintained for this dehydration and dehydrogenation process?
This means that only the pressure on the pump needs to be taken into account; it should be a dehydration process, what about dehydrogenation?
Like, it covers quite a lot of aspects. What is the oil temperature in the high-level oil tank under normal operating conditions? If the oil temperature in the high-level oil sump remains high over a long period of time, with no water detected and no light oil present, what could be the possible causes?
