High viscosity
rotor pump in daily use pay attention to the preservation of electric oil pump should be placed in a dry, clean and corrosive gas-free environment. Save each part and replace the same part, when disassembling and inspecting the high viscosity rotor pump, you should save each part, and pay special attention to the flameproof surface of the flameproof part can not make its damage, including insulation gasket and casing, if there is damage, you must replace the new same part, do not use substitute materials lower than the performance of the raw materials or parts that do not conform to the original specifications, and install all the parts according to the original position during assembly.
High viscosity rotor pump often grease, electric oil barrel pump for high-speed operation, grease is easy to volatilize, so it is necessary to keep the bearing lubrication clean, and pay attention to replacement. High viscosity rotor pump regular inspection and maintenance, electric oil barrel pump should often check, maintenance, should check the power cord: internal wiring, plug, switch is good, insulation resistance is normal, brush tail seat is loose, commutator and brush contact is good, high viscosity rotor pump armature stage expansion stator winding is moderate open phenomenon, bearing and rotating parts damage and so on.
Pay attention to the insulation resistance of the high viscosity rotor pump. For the electric pumping pump which is not used for a long time or used in a wet environment, the insulation resistance of the winding must be measured with a 500 meter before use. If the insulation resistance between the winding and the motor shell is less than 7, the winding must be dried.
