Stainless steel rotary pumps should be stored in a dry, clean, and non corrosive gas environment during daily use. Save each part properly and replace the same parts. When disassembling and inspecting high viscosity rotor pumps, each part should be well preserved. Special attention should be paid to the explosion-proof surface of the explosion-proof parts, including insulation pads and sleeves, which should not be damaged. If there is damage, new identical parts must be replaced, and substitute materials with lower performance than the raw materials or parts that do not meet the original specifications should not be used. During assembly, all parts should be installed in their original positions without omission.
Stainless steel rotor pumps are often greased, and electric oil drum pumps operate at high speeds, making lubricating grease easy to evaporate. Therefore, it is necessary to keep the lubrication at the bearings clean and pay attention to replacement. High viscosity rotary pumps should be regularly inspected and repaired, and electric oil drum pumps should be regularly inspected and repaired. The power cord, internal wiring, plug, switch should be checked for good condition, insulation resistance should be normal, the brush tail seat should be loose, the commutator should be in good contact with the electric brush, the armature winding stage should be expanded, and there should be moderate open circuit in the stator winding, as well as damage to the bearings and rotating parts. Attention should be paid to the insulation resistance of high viscosity rotary pumps. For electric pumping pumps that have been unused for a long time or used in humid environments, 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 casing is less than 7, the winding must be dried.
