industrial equipment repair

The company has the test laboratory corresponding to the criteria of system accreditation of the Republic of Belarus and accredited on conformity to the requirements of ISO/IEC 17025.

All types of tests of low-voltage and high-voltage AC and DC electric motors in the process of repairs and in the assembled mode
(no load and under load)

• Industrial chamber electric furnaces
• Impregnating installations
• AC and DC electric motor test benches
• Automated installations for shafts surfacing
• Balancing machines

Furnaces are designed for various types of heat treatment products, blanks, materials and tools. The furnace is one of the most common types of thermal equipment due to its use in various technological processes: drying impregnating compound, sintering composite materials and in many other types of heat / heat treatment of various metal products or polymers within 400 ° C.

We design and manufacture annealing furnaces for insulation windings materials of electrical machines with a three-stage electrical afterburner of gaseous substances. The maximum temperature is 600 ° C.

Inductive drying furnaces are designed for drying products of various purposes, including windings of electrical equipment in the air at the temperature from +50 to + 250 ° C.

The main advantage of the furnace is its fire safety because there is no direct circuit contact of the heater with inner surface of drying cabinet.

Resistance furnaces designed for drying products for various purposes, including windings of electrical equipment in the air at temperature from +50 to + 400 ° C in stationary conditions. In this model of furnace the heating of the inner chamber is carried out by electric heating elements.

• Independent groups of heating elements provide the ability to control the speed of the furnace to the operating mode, it is possible to use part of heating elements to maintain the temperature
• Quick set temperature

The impregnating installation is intended for impregnating products with an impregnating compound using the «vacuum pressure» technology in an automated and manual mode.

The use of vacuum pressure impregnation (VPI) is accepted by all the world leaders in mechanical engineering: Siemens, ABB, WEG, Alstom, General Electric etc. The impregnating installation increases the reliability of the product, protects it from dirt and moisture.

Test benches are intended for carrying out acceptance tests of synchronous and asynchronous electrical machines of alternating and direct current.

Test benches classification:

• AC motor test bench for direct starting (no load)
• AC motor test bench for inverter-based (no load)
• AC motor test bench for inverter-based (under load, short-circuit test) with a load generator of direct current with energy recuperation
• DC motor test bench (no load)
• DC motor test bench (under load)
• AC motor test bench for inverter-based (under load, short-circuit test) using as a generator asynchronous motor with a squirrel cage rotor

The surfacing allows you to restore physically worn and deformed surfaces of the shafts, returning them to their original dimensions, as well as significantly increasing their strength and corrosion resistance, significantly extend the operation life of the shafts. Surfacing is performed on special automated welding installations using wire as a surfacing material.

Characteristics:

• Rotor balancing
• Balancing inboard and outboard rotors of various designs and types (rotors of electric motors, turbines)
• Balancing of parts that do not have their own bearing surfaces (disks, fans, pumps) on special mandrels
• Rotor balancing on their own bearings
• Drive shaft or belt shaft drive type
• Energy recuperation during rotor braking
• Spindle drive from a squirrel cage induction motor
• Electric motor power supply from a frequency converter
• Applied digital indicator devices
