Looking for a job as a steam turbine operator, what does a steam turbine equipment installer do?

I went to this machine, which I played with for 5 years, older than I am, and it was obsolete.

The main tasks he is engaged in include:

1) Dismantle and inspect the parts of the steam turbine body and auxiliary equipment;

2) Eliminate equipment defects;

3) Assemble and install the steam turbine equipment;

4) Clean the pipes and ancillary parts of each system;

5) Participate in the trial operation of steam turbines, generators and subordinate stimulus systems and the trial operation of steam turbine generator sets;

6) Fill in the lead inspection and test records of steam turbine and parts and test operation records of steam turbine generator sets.

The following types of work are classified as occupations:

Steam turbine body installer, steam turbine speed control installer, steam turbine auxiliary equipment installer.

Look for a job at an ocean company or a shipping company.

The working principle of the steam turbine includes the working principle of the steam turbine stage and the working principle of the entire steam turbine unit. The principle of operation of the steam turbine involves the flow of steam, the generation of forces on the blades and the formation of losses, and the method of adapting the steam turbine to changes in external loads.

According to the way in which the energy contained in steam is converted into mechanical work in the turbine stage, the steam turbine stage can be divided into three types: impulse stage, reaction stage and speed stage. The steam expands in the nozzle and the pressure drops from the inlet to the outlet.

As the cross-sectional area of the nozzle flow channel gradually decreases, the velocity of steam in the nozzle gradually increases. The energy contained in the steam is converted into the kinetic energy of the vapor flow, the absolute velocity of the flow out of the nozzle. Since the circumferential velocity of the moving blade is, the relative velocity of the steam entering the moving blade.

There is no change in the pressure as the steam flows through the moving vanes, i.e. the pressure at the outlet of the moving vane is equal to the pressure at the inlet.

When the steam flow through the moving blade, the direction changes, and the momentum of the steam flow also changes, so the force on the moving blade pushes the rotor to rotate and do work. The shape of the impulsive moving blades is close to left-right symmetry.

At the inlet and outlet of the nozzle and the moving blade, the magnitude and direction of the vapor velocity can be expressed in a certain proportion by the size and direction of the vector line segments, which form the so-called velocity triangle.

The steam turbine is a progress of the steam engine, and both the steam engine and the steam turbine are propelled by steam to do work. In a steam engine, steam drives the pistons in the cylinders to reciprocate and gain power. Steam turbines are powered by steam propelling rotors to rotate.

The steam turbine is generally composed of a partition (installed with static blades) and a rotor (installed with moving blades), after the high-temperature and high-pressure steam passes through the static blades, the steam obtains a high speed, and the high-speed steam drives the moving blades to rotate when passing through the moving blades, and the rotor rotates at high speed to drive the generator, so as to obtain power output.

The boiler uses coal or gas to generate heat, so that water or mixed liquid becomes high-temperature and high-pressure steam, and provides steam power to the high-pressure unit of the steam turbine through the pipeline, so that the rotor blades of the high-pressure unit rotate at high speed under steam power, and enters the medium-pressure unit to drive the medium-pressure rotor to rotate after cooling and depressurization, and enters the low-pressure unit to drive the low-pressure rotor to rotate after cooling and depressurization again, and makes the steam turbine rotor reach the rated working speed through combined power to drive the generator to send out electric energy. This is the conversion process of solid energy to thermal energy and steam kinetic energy to mechanical energy to electrical energy.

It rotates under the impetus of steam and carries a generator or other equipment to do the work.

The steam impulses the turbine blades, the blades drive the steam turbine rotor to rotate, and the steam turbine rotor and generator rotor rotate coaxially.
