Description
Technical field
The present invention relates to turbines, in particular to a kind of pipeline suppressing surge.
Background technology
Surge is under a kind of damage that turbine is occurred when flow is reduced to a certain degree
Vibration, has the most serious harm for turbine.
The method of at present conventional suppression surge is, system judge to carry out during equipment generation surge to shut down or
Improve rotating speed and prevent surge.But shut down the seriality that the equipment that affects uses, accelerate turbine
Rotating speed then can shine into energy waste.
Therefore for solving resource and the problem of energy waste that existing suppression surge causes, it is necessary to provide
A kind of simple in construction, suppresses the suppression surge of the generation of surge under reducing the loss of energy and resource
Pipeline.
Summary of the invention
In view of this, the invention aims to overcome deficiency of the prior art, it is provided that one
Plant simple in construction, under reducing the loss of energy and resource, suppress the pipe of the suppression surge of the generation of surge
Road.
For solving the problems referred to above, the solution that the present invention provides is as follows:
A kind of pipeline suppressing surge, including turbine, described turbine is provided with intake stack and air-out
Pipeline,
The pipeline of described suppression surge also includes that bypass pipe, described bypass pipe are connected to described intake stack
