Abstract

The invention relates to a coupler connecting structure applicable to switching of backpressure rotors of a low-pressure cylinder. The coupler connecting structure applicable to switching of the backpressure rotors of the low-pressure cylinder comprises a high- and medium-pressure rotor connected with one end of a low-pressure rotor through a first coupler, and the other end of the low-pressure rotor is connected with a generator through a second coupler. The coupler connecting structure is characterized in that each of the first and second couplers is provided with a first drawing bolt, a taper sleeve is perpendicularly sleeved on the first drawing bolt, a support ring is connectively arranged on the taper sleeve and connected with a support block, a spacer is assembled on the support block, and a hydraulic head is installed on the spacer. The coupler connecting structure has the advantages that good switching of the double rotors is guaranteed, and mounting accuracy and assembling quality are guaranteed. Besides, the coupler connecting structure is simple in structure, convenient to mount and demount, high in mounting accuracy, stable and reliable, and meets the requirements of connection of the 'high- and medium-pressure cylinder-low-pressure cylinder-generator' coupler in a turbine.

Description

technical field [0001] The invention belongs to the technical field of heat-supply and energy-saving transformation of large and medium-sized steam turbine low-pressure cylinder back-pressure rotors, and in particular relates to a coupling connection structure suitable for low-pressure cylinder back-pressure rotor interchange. Background technique [0002] Large and medium-sized units basically use steam extraction condensing turbines, and cogeneration generally uses steam extraction for heating. Compared with back pressure heating, the economic benefits of extraction steam heating are much different. Back pressure heating is the most economical. Theory The energy utilization rate is 100%. A large and medium-sized steam turbine low-pressure cylinder back-pressure rotor interchangeable circulating water heating energy-saving transformation technology came into being, that is, the low-pressure rotor uses the original design pure condensing rotor to generate power duri...
