1. Temperature failure of  high temperature vacuum furnace:jUQMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

Causes: (1) The thermocouple wire is disconnected or contaminated (2) The temperature control instrument is faulty (3) The thermocouple compensation wire is connected reversely or short-circuitedjUQMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

Remedy: (1) Replace the thermocouple (2) Repair according to the instrument manual (3) Reconnect or eliminatejUQMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

3. The oil temperature is too high:jUQMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

Causes: (1) Sundries are sucked into the pump (2) The temperature of the sucked gas is too high (3) The amount of cooling water is insufficientjUQMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac

Remedy: (1) Remove debris (2) Install a cooling device on the air inlet pipe (3) Enhance the cooling water flowjUQMuffle Furnace,Tube Furnace,Vacuum Furnace,Atmosphere Furnac
