What valves are there at the inlet of the heat transfer oil circulation pump? We import two stop valves currently; there is a filter between the stop valves, and at the outlet there is a check valve and another stop valve. Are there any other devices?
It should be gone, but it’s better to install a pressure gauge at the point of intake, so as not to rely on experience when driving
Not going into the heater? Not going into the condenser? Install a drain line; although the filter can be removed, it’s not as comfortable after all without a drain line. If we are to consider the effect of temperature on heat transfer oil. . Should we install a pressure balance tube?
What’s the purpose of a pressure balance tube? Is there a diagram I can take a look at?
I’ve resigned; it’s been almost a year now. When the temperature of the heat transfer oil used is low, its viscosity is high and its coefficient of expansion is also high. The balance tube connects the pump inlet pipe to the upper tank; its function is to buffer the pressure changes caused by the expansion of the liquid. It also prevents waste during pump removal and maintenance, and makes things easier.
