>Submersible pump comprehensive monitoring controller oil chamber water immersion winding overheating heating dehumidification protector
． Overview
Type water pump comprehensive protector> (hereinafter referred to as the protector) is suitable for the protection and control of submersible sewage pumps, clean water pumps, B axial flow pumps, and B mixed flow pumps produced by Nanjing Lanshen Pump Group Co., Ltd. Or all other similar water pumps, such as Kaiquan, Kaishili, B, etc.
． Scope of application
The controller is panel mounted and can work normally under the following conditions:
The ambient temperature does not exceed >+ degrees, the average temperature within an hour period does not exceed + degrees, and the minimum ambient temperature must not be lower than Yudu.
There must be no excess dust or acid in the air
Input voltage: >,, Rated, salt, corrosive gas, relative humidity shall not exceed when the maximum temperature is + degrees, and higher temperatures are allowed when the temperature is lowered. relative humidity.
For example: When the humidity is below 10 degrees, you should be careful about condensation that may occur accidentally due to temperature changes.
The altitude of the installation site shall not exceed > meters.
The vertical installation inclination shall not exceed > degrees.
