a.When the current of the circulating pump is lower than normal, the efficiency of circulating pump is reduced, the flow rate is decreased, and the heating line can be fouled up and should be cleaned. When the current of the circulating pump is lower than normal, the efficiency of circulating pump is reduced, the flow rate is decreased, and the heating line can be fouled up and should be cleaned.
b.The circulating pump pressure is constant, the current increases and the flow rate decreases, it is the heat conduction liquid metamorphosis, the viscosity increases, should replace or regenerate in time.
c.The circulation pump current is reduced, the pump pressure is zero, and the pump is empty. It may be the vaporization of oil and the measures for the cause of evaporation. If the filter is blocked, the circulation pump should be opened and the filter should be opened immediately. If the gas containing water or water decomposition of the new heat transfer fluid is not excluded in the system, the exhaust valve should be opened immediately.
2.Liquid phase heat carrier furnace outlet temperature is low, heat quantity is insufficient, and smoke exhaust temperature over 300 ℃, are mainly dust problem, should be blowing in a timely manner. If the smoke temperature is low, the main is combustion problem, mainly is to lead the wind not enough. Although the stove is under pressure, the air volume is not much, the furnace temperature is low, the combustion intensity is not enough. It is important to inspect the back of the furnace to be sealed off from the dirt, dust, etc., whether it is sealed or not.
3.The pressure drop of the filter is increased, the pressure drop of the pump inlet, may be the filter network block, should open the bypass, remove the filter to clean.
4.Common fault and treatment of chain grate
a.The grate stops, may be a chain too loose, or the sprocket wears badly, and the chain is not connected to the chain. Adjust the adjustment screw on both sides and tighten the grate. If it is not normal, then switch the sprocket.
b.Grate stuck. The reason is often that the lining of the grate is broken or the fire is loose. There is a metal inclusion in coal that will trap the grate; Grate of fire grate; The tip of the hawk sinks and gets stuck in the grate. Processing method: inverted by means of a grate started again after removing debris, replace the broken link, such as start and then gets stuck, then stop running after detailed check the reason and solve. If the eagle is sinking, the door of the fire can be pulled on both sides.
