Description

Technical Field

[0002] The turbine shell is a high-tech product, which is mainly composed of a shell, an impeller, a bearing, a sealing ring, an intake pipe and other components. The working principle of the turbine shell is to use the exhaust gas energy to drive the turbine, and then transfer the power generated by the turbine to the compressor, thereby improving the engine output power and fuel efficiency; the turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial impact of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber. The turbine drives the coaxial impeller, which presses the air sent by the air filter pipe to pressurize it into the cylinder, thereby increasing the output power of the engine. The turbine shell can make the engine output greater power at low speeds, improve the engine's climbing performance and acceleration performance; at the same time, the turbine shell can also increase the engine's output torque in the low and medium speed sections, improve the engine's climbing ability and off-road performance; the turbine shell can also effectively improve the engine's fuel efficiency, so that the fuel can be more fully utilized. After the production of the turbine shell, it needs to be leak tested and marked, so the corresponding leak test marking equipment is needed.

In this example, the guide seat 25 is adapted to the turbine shell so as to play a guiding role, and the support rod 2 1 is connected with a baffle plate 23 at the other end, and a spring 24 is sleeved between the baffle plate 23 and the support block 16 on the outside of the support rod 21, and a positioning assembly is provided inside the support block 2 17.

When the support block 16 moves, it will drive the head 22 to dock with one end of the turbine shell through the support rod 21 to seal it, and at the same time, one end of the support rod 21 will push the baffle 23 to stretch the spring 24 , so that the reverse force generated by the deformation of spring 24 is transmitted to the head 22, so that it fits tightly with the turbine shell, and at the same time, the support block 21 will drive the boss 19 to continuously approach the turbine shell, and at the same time, the boss 19 that is squeezed and in contact with the turbine shell will move into the chamber, thereby pushing the stopper 20 to squeeze the spring 18, and the reverse force generated by the spring 18 acts on the boss 19, so that it limits and fixes the turbine shell, so that it can change accordingly according to the shape of the turbine shell so as to adapt to it and better fix it. When in the step of adjusting the position of the support block 16 and the support block 21, if you want to make the pressure acting on the turbine shell greater, adjust the corresponding support block 21 or the support block 11 to be closer to the position of the turbine shell, otherwise, move away from it, so as to change the clamping force on the turbine shell and change its fixing effect, which is more convenient to use and more practical.
