Description

Technical Field

[0001] The invention relates to the technical field of steam turbine shock absorption, in particular to a steam turbine shock absorption protection seat. Background Art

[0002] A steam turbine is a reciprocating power machine that converts steam energy into mechanical work. Steam is sent to the cylinder through pipes. The valve controls the time when steam reaches the cylinder. It enters the slide valve chamber through the main steam valve and the regulating valve, and enters the left or right side of the cylinder alternately under the control of the slide valve. The steam pushes the rotor to do work in the cylinder. The cooled steam is introduced into the condenser through the pipe and condensed into water again. This process is repeated continuously when the steam turbine is working. The steam turbine is prone to vibration during operation, so when the steam turbine in the power plant is used, it needs to be equipped with a corresponding shock-absorbing base to ensure normal operation.

[0003] When the existing power plant steam turbine shock-absorbing base is in use, the shock-absorbing method for the steam turbine is relatively single, so that the shock-absorbing effect is not good enough, so that vibration will occur when the steam turbine is in use. At the same time, the connection between the existing shock-absorbing base and the power plant steam turbine is very inconvenient, so when the shock-absorbing base fails for maintenance, it is not convenient to remove the power plant steam turbine, which is not conducive to the use of the shock-absorbing base.

After ensuring that the fixed plug plate 203 is inserted into the fixed slot, the fixed plug plate 203 can tighten the inside of the fixed slot and can make the fixed pressure plate 203e shrink toward the sliding push plate 203a, so that the oblique sliding column 203d can tighten the tightening spring 203c through the sliding top plate 203b, thereby enhancing the fixing effect of the turbine body 104. Start the turbine body 104, observe its operation, and ensure that the shock-absorbing protection seat can effectively reduce the vibration of the turbine body 104. Ensure that the sliding pressure plate 202b pushes the sliding block 202d to squeeze the shock absorbing spring 202f through the pushing rod 202c, thereby damping the steam turbine body 104. Ensure that the sliding cone 202b-2 can push the inclined surface of the trapezoidal slide plate 202b-3 through its cone surface, so that the trapezoidal slide plate 202b-3 slides inside the sliding groove 2 and can press the telescopic guide rod 202b-4 to shrink. At the same time, by squeezing the buffer spring 202b-5, the damping effect on the steam turbine body 104 is enhanced.
