Thermal power generator bedplate grouting material block construction methods

Thermal power generator turbine generator bedplate grouting material block construction methods is the 'heart' of the power plant. If the steam turbine generator bedplate and block poor contact, can cause the vibration and affect the safe and stable operation of power plants. Must make the pledge that we shall, therefore, bedplate and block contact surface level off, the guarantee rate of contact area can meet the demands of high precision, and to ensure that the steam turbine generator bearing is reasonable. Bedplate of steam turbine generator block USES high-strength non-shrink grout material replace traditional shim can better meet the technical requirements, such as bearing capacity, construction period, reduce human aspects has a significant effect, is becoming more and more widely applied. Grouting material suitable for power plant steam turbine generator bedplate grouting material block the construction of grouting grouting process principle of grouting material have the characteristics of their performance is good, used in the construction of turbine bedplate template height difference on both sides, make grouting material flow freely, in this state and turbine bedplate bottom contact closely, reach the contact area between block and bedplate flat, so that contact area rate. Grouting material block casting casting, casting in two times. In the first layer after pouring began pouring the second 20 to 40 minutes. The pause time is too long can lead to isolation layer. Best environment temperature should be 15 ~ 25 ℃, the first casting about 40 mm high, bedplate of injection nozzle should be lower than the bottom 30 ~ 40 mm. In the first layer started pouring casting after the completion of 20 ~ 40 minutes the second layer, casting the second layer, should be until the mortar overflow sprue gate to stop pouring. After pouring after 20 ~ 40 minutes, use the deck along the table edge to edge 'fat' isolation.
