Description
Technical Field
The utility model relates to a turbine technical field, concretely relates to built-in external device that changes of turbine cylinder piston rod.
Background
The TRT device is power equipment which utilizes pressure energy and heat energy of blast furnace top gas which is a byproduct of blast furnace smelting to enable the gas to work through a turbine expander, converts the gas into mechanical energy and then converts the mechanical energy into electric energy, and is widely applied to iron and steel enterprises. The servo oil cylinder is an automatic adjusting system executing mechanism in the TRT device and is generally directly connected with a turbine shell, a piston rod of the servo oil cylinder reciprocates to drive a linkage ring to do axial reciprocating motion, and the linkage ring drives a first-stage stationary blade to do adjusting motion through a sliding block and a crank. The position of a bearing cylinder of the existing TRT device inevitably generates gas leakage, the gas is leaked into a cylinder cavity and continuously accumulated, strong acid medium components in the gas are attached to the surface of a piston rod of the oil cylinder to form corrosion, pits appear on the surface of a chromium coating of the piston rod, along with the increase of the pits, the sealing of the servo oil cylinder is continuously damaged when the servo oil cylinder reciprocates, a large amount of hydraulic oil flows into a gas system through the cylinder cavity, so that the oil level of the hydraulic oil is sharply reduced, and meanwhile, a great potential safety hazard is caused to a pipe network gas system. And the servo oil cylinder is directly connected to the turbine shell, and because a large amount of coal gas exists in the oil cylinder chamber, the oil cylinder cannot be directly replaced on line, the machine must be stopped, replaced and replaced, the process is complicated, and the time is consumed.
Therefore, in order to reduce the damage of the oil cylinder seal caused by the corrosion of the gas on the piston rod, the internal rotation external device of the oil cylinder piston rod of the turbine is necessary.
SUMMERY OF THE UTILITY MODEL
To built-in easy strong acid medium in the coal gas of hydro-cylinder piston rod corrodes and lead to the technical problem of the sealed damage of hydro-cylinder in the hydro-cylinder cavity, the utility model provides an external device of built-in commentaries on classics of turbo-machine hydro-cylinder piston rod, the device can avoid hydro-cylinder piston rod and coal gas direct contact, effectively prolongs piston rod life and obviously reduces the sealed risk of damaging of hydro-cylinder.
The utility model provides a built-in external device that changes of turbine cylinder piston rod, the device includes adapter sleeve and extension axle, adapter sleeve one end is fixed on the hydro-cylinder, and the other end is fixed on turbine housing, the extension axle is connected with the hydro-cylinder piston rod, the adapter sleeve is close to turbine housing one side tip and is equipped with seal assembly and the gland that matches with the extension axle in proper order, be equipped with the filler between gland and the seal assembly.
Further, a sealing ring is arranged in the sealing assembly.
Further, the size of the sealing rings is 6mm for hot tails 48.
Further, the number of the sealing rings is 2.
Furthermore, 4 paths of 10mm packing seals are arranged between the packing gland and the sealing assembly.
The utility model has the advantages that,
the utility model provides a turbine oil cylinder piston built-in external device, which is connected with an oil cylinder and a turbine shell through a connecting sleeve, thereby realizing the separation of the oil cylinder and the turbine shell; by arranging the extension shaft, the insufficient stroke of the oil cylinder caused by additionally arranging the connecting sleeve is compensated; the sealing component can avoid gas leakage to form a first section of gas seal; the packing gland is internally provided with packing seal, the packing gland is fastened in the daily operation process to prevent the gas from leaking outwards, and a second section of gas seal is formed, so that the piston rod of the oil cylinder is not directly contacted with the gas.
The utility model avoids the direct contact between the piston rod and the coal gas, and effectively prolongs the service life of the piston rod; the structure is simple, and the normal working state of the oil cylinder is not influenced; the filler is sealed and fastened daily without using excessive manpower and material resources; if leakage occurs during operation, the machine can be replaced without stopping the machine, and only the piston rod and the extension shaft are disassembled to carry out replacement operation.
