Hot oil pump preheating issue
Thread Content
How can I control the preheating of the hot oil pump? The required rate of temperature increase is no more than 50 degrees per hour, but I keep failing to prevent the temperature from rising too quickly.
Reduce the preheating temperature; during the preheating process, rotate the turbine
Do not open the valves on the preheating line too wide; open them gradually. If there is a thermometer, use it; otherwise, a temperature probe can be used
The standard procedure requires that the preheating of the hot oil pump be carried out at a rate of 50°C per hour. However, it is important to be careful during this process; one should avoid introducing oil too quickly, instead opening the inlet valve slowly to allow the pump body to warm up gradually. Preparing the pump for operation should only be done once the temperature reaches that of the material being processed. Too fast a speed can lead to leaks and rotor jamming; during the preheating phase, we rotate the rotor every half hour. Special attention must be paid to the cooling of the pump, as well as its lubrication and sealing flush systems.
Find someone to handle it specifically, and do so carefully.
