Nowadays, the application fields of oil pump motors are continuously expanding, and the demand for high power density motors with various special protection functions is increasing. Today, the editor of Dalan Motor will give you an analysis of the type of motor protection, specific methods and measures for internship.
1. Application environment and protective measures
(1) In the room with normal medium, the protective type is generally selected. Under the condition of ensuring the safety of the person and equipment, the non-protective type can be selected. When there may be dripping or splashing at the place of use, the drip-proof or splash-proof type should be used.
(2) In the humid tropical area, the humid tropical type should be adopted as much as possible. If the ordinary type is adopted, there must be appropriate and effective moisture-proof measures.
(3) Where there is often more dust in the air, if it is conductive dust, the dust-tight type should be used; when it is non-conductive dust, the dust-proof type should be used.
(4) Where corrosive gas or free matter is often present in the air, the chemical anti-corrosion type and pipeline ventilation type should be adopted.
(5) In the open air environment, if there are measures to prevent the sun, rain, snow, wind and sand, etc., the dust-proof type can be used.
(6) In explosion and fire hazard environments, explosion-proof type should be selected according to the partition level
(7) Motors with insulation class H, F and C should be selected in high-temperature places.
Second, how to choose the motor protection form
During the maintenance of the motor, it was found that the failure of the motor in many cases was caused by the damage of the motor's protective measures. Regardless of whether it is an electric motor or a generator, the protective form of the motor should be selected from one of open, protective, enclosed and explosion-proof according to the working environment.
(1) The air inside the open motor can communicate with the outside, and the heat dissipation conditions are very good, but its live parts and rotating parts have no special protection, and can only be used in a dry and clean working environment.
(2) Protective motors include drip-proof, splash-proof, and mesh-cover types, which can prevent water droplets and water slurry in a certain direction from falling into the motor. Although their heat dissipation conditions are worse than the open type, they Is widely used in production.
(3) Enclosed and explosion-proof motors: Motors with completely enclosed enclosures are widely used in dusty and humid environments. In explosive gas environments, enclosed explosion-proof motors should be used. The enclosure must have a tightly sealed structure and High mechanical strength.
