The Solenoid Turning Gear MFJ1-4 is an electromagnet suitable for dry valves and is widely used in the turning system of turbines in power plants. It is mainly used to control the electromagnetic reversing valve in the hydraulic system to ensure that the turbine can be turned smoothly before starting and after shutdown.

Structural features

1. AC single-phase solenoid type: The Solenoid Turning Gear MFJ1-4 adopts an AC single-phase solenoid design, and all parts are installed in an aluminum alloy die-cast housing with good protection performance.

2. No built-in reset device: The electromagnet itself has no reset device, but relies on the spring reset of the valve body. When the current is not connected, the armature is pushed out to the rated stroke distance by the valve body push rod; after the power is turned on and attracted, the electromagnetic force is generated to move the valve stem to achieve the purpose of controlling the opening and closing or reversing of the oil circuit.

3. Rated suction and stroke: The rated suction of MFJ1-4 is 40N and the rated stroke is 6mm.

Installation and use conditions

1. Ambient air temperature: not higher than +40℃, not lower than -5℃.

2. Installation site altitude: not more than 2000 meters.

3. Humidity: When the maximum temperature is +40℃, the relative humidity of the air shall not exceed 50%. At lower temperatures, higher relative humidity can be allowed, such as 90% at 20℃. For occasional condensation due to temperature changes, appropriate measures should be taken.

4. Environmental pollution level: Level 3.

5. Installation environment: It should be installed in a place without significant shaking and impact vibration, and there should be no gas and dust that can corrode metal and damage insulation in the use environment.

Solenoid Turning Gear MFJ1-4 is mainly used in the turning system of steam turbines in power plants to ensure smooth turning operation before and after the unit is started. The main function of the turning device is to turn the shaft system of the steam turbine generator set before or after the unit is started to prevent the main shaft of the steam turbine generator set from bending due to long-term static.

Solenoid Turning Gear MFJ1-4 plays a key role in the cranking system of the steam turbine in the power plant. Through its reliable structure and performance, it ensures the smooth cranking operation of the steam turbine before startup and after shutdown. Correct installation and use conditions, as well as regular maintenance and inspection, can effectively extend the service life of the equipment and ensure the stable operation of the power plant.
