YBT series liquid variable resistance starting speed controller

I. Overview
The YBT series liquid variable resistance starting speed controller is mainly used for the starting and speed regulation of large and medium-sized wound AC asynchronous motors for fans, water pumps, and other similar equipment in industrial sectors such as building materials, steel, chemical, and metallurgy. It achieves the purpose of adjusting the motor speed by changing the resistance of the series connection of the motor rotor circuit, and is the main choice for energy-saving transformation of large and medium-sized fans and pumps. The technical level of this product is leading among domestic peers.

2、 Performance advantages of YBT series liquid variable resistance starting speed controller

1. We can provide stepless speed regulation for large wound asynchronous motors, with a speed ratio of up to 2:1. If users require, our company can also provide speed regulators with larger speed ratios.
2. It is also used for starting electric motors without the need for additional starting devices, and has the advantages of low starting current and smooth starting with liquid resistance starters.
3. Compared with variable frequency speed regulation and thyristor cascade speed regulation, it is more economical, reliable, practical, and easier to maintain.
4. Compared with hydraulic couplings, it has flexible layout and is more convenient to use.
5. Because the air volume is proportional to the rotational speed, this regulator has better linearity in adjusting the air volume

3、 Environmental conditions for use

1) The upper limit of ambient air temperature shall not exceed+50 ℃, and the lower limit shall not be lower than -5 ℃; The relative humidity of the atmosphere shall not exceed 85%;
2) The water used for preparing electrolytes and supplementing during operation should be distilled water, softened water, or boiled water that has been left to stand. It must be pure and free of sediment and suspended solids.
3) In a medium without explosive hazards, and without gases and dust that can corrode metals and damage insulation (including conductive dust)
