This utility model discloses a felt resistance support, including a support, a fixing block on the side of the support, a sleeve on the fixing block, a first felt sheet inside the sleeve that contacts the side of the fixing block, a groove at the end of the sleeve away from the support, a second felt sheet inside the groove, a pressing column inserted into the fixing block that contacts the side of the first felt sheet, a resistance spring and a housing on the outer side of the sleeve, the resistance spring being located between the sleeve and the housing, an iron pin on the resistance spring, a sliding groove on the inner side of the housing, the iron pin being slidably connected in the sliding groove, and an adjustment component on the support. This utility model adjusts the force of the pressing column pressing the first and second felt sheets by screws and nuts, thereby adjusting the frictional resistance between the sleeve, the pressing column, and the fixing block, thus achieving adjustment and control of the sleeve's rotation speed.

This invention discloses a cutting fixture and method applied to the removal of compressor moving blades in a gas turbine. The cutting fixture includes: a support module positioned on the compressor disc, the support module having a hollow groove suitable for the compressor moving blade to pass through, with a gap between the hollow groove and the compressor moving blade; a guide module disposed on the support module, suitable for moving axially along the compressor disc; and a cutting module disposed on the guide module, having a cutting end positioned directly above the gap during cutting, suitable for axial cutting along the compressor disc via the guide module. The support module of this invention positions the cutting module, eliminating the need for operators to hold an angle grinder. The guide module provides linear guidance for the cutting module, ensuring that the cutting groove cuts linearly along the compressor disc axis, preventing the cutting angle from wobbling due to unstable handling and avoiding accidental damage to the compressor disc.

This invention relates to the field of refrigerant flow control technology, and in particular to an electronic expansion valve throttling mechanism and an electronic expansion valve. The electronic expansion valve throttling mechanism includes a valve needle and a valve seat. The valve needle is mounted on the valve seat and has a moving path along the valve seat axis. The valve needle includes a first valve needle segment and a second valve needle segment from top to bottom, with the interface between the first and second valve needle segments forming a first cross-section. The valve seat includes a first valve seat segment and a second valve seat segment, with the interface between the first and second valve seat segments forming a second cross-section. The top of the first valve seat segment forms a first end face, and the bottom of the second valve seat segment forms a second end face. The first end face is provided with a first throttling outlet, and the second end face is provided with a second throttling outlet. A refrigerant inlet hole is provided on the side of the second valve seat segment. The present invention provides a single electronic expansion valve that can achieve throttling control of both large and small flow rates, and it has a simple structure, high modularity, and low cost.

The application provides a compressor air intake cooling system and compressed air energy storage system, and belongs to the technical field of compressed air energy storage. The compressor air intake cooling system comprises a compressor, a double-fluid nozzle integrated component, a gas supply path and a liquid supply path. The compressor has an air inlet and an air outlet. The double-fluid nozzle integrated component is installed on the air inlet, and the outlet of the double-fluid nozzle integrated component is communicated with the air inlet. One end of the gas supply path is connected with the gas channel of the double-fluid nozzle integrated component, and the other end is connected with the air outlet. One end of the liquid supply path is connected with the liquid channel of the double-fluid nozzle integrated component, and the other end is connected with a cooling liquid storage device. The double-fluid nozzle integrated component is used to provide a lower pressure without high temperature, so that a high gas-liquid flow rate difference can be realized, liquid fine atomization can be realized, the lower pressure can effectively reduce the nozzle wear rate, the maintainability can be improved, the installation requirements of the pipeline and equipment can be reduced, and the reliability and safety of the system can be improved.
