The invention discloses a rubber shock absorber mainly comprising a metal mounting seat, a stiffening ring, a locating shaft and rubber supports, wherein the rubber supports are made of vulcanized rubber and are respectively arranged between the locating shaft and the stiffening ring and between the stiffening ring and the mounting seat; the three parts, namely the metal mounting seat, the stiffening ring and the locating shaft are all metal parts, the surfaces, which are in contact with rubber, of the three parts are all vulcanized, and the three parts are combined into a whole through the rubber; the mounting seat, the stiffening ring and the locating shaft are not in contact with one another, so that the locating shaft can be elastically connected with the mounting seat; an unthreaded hole or a threaded hole is formed in the center of the locating shaft; and the metal mounting seat and the locating shaft are both designed at a certain angle, and the connecting boundaries of the rubber and metal are in circular arc transition, so that stress concentration caused when the shock absorber works can be reduced. When the rubber shock absorber is fixed through the locating shaft and the mounting seat when being mounted, the formula of a rubber material is optimized, and the effects of shock absorption and noise reduction are effectively taken; and the structure and the stress state are reasonable, the durability of the rubber shock absorber is improved, the service life of the rubber shock absorber is prolonged, and the rubber shock absorber has a relatively high application value.

The invention discloses a coaxial matching clamp for detecting the performance of a frequency response method transformer winding deformation on-line monitoring sensor, and the clamp consists of a supporting fixed part and a uniform transmission line, and the supporting fixed part comprises an upper cover plate, a lower supporting plate, a left supporting plate and a right supporting plate, and isused for supporting a detected sensor and the uniform transmission line; the lower supporting plate is provided with an insulating neck, and a tested sensor is fixed on the insulating neck and located between the left supporting plate and the right supporting plate. The uniform transmission line penetrates through the centers of the left support plate, the right support plate and the measured sensor, and is connected with the left support plate and the right support plate through conical transition sections; two ends of the uniform transmission line are respectively provided with a signal connection terminal. Based on the coaxial matching clamp, the performance of the sensor is detected, the influence of external uncertain factors on the detection result can be avoided, and the detectionefficiency is improved. The performance parameters of the sensor are ensured to meet application requirements.

The invention relates to the technical field of boiler structures, in particular to a gas-fired boiler. After the gas-fired boiler is remolded, the performance parameters of an original CFB boiler are retained, and natural combustion of fuel gas is guaranteed. A gas burner is mounted at the bottom of a hearth. An SOFA opening is formed in the side wall of the hearth. The upper end of the hearth communicates with a connecting flue. The connecting flue comprises a horizontal flue body, a vertical ascending flue body and a vertical descending flue body. The vertical descending flue body communicates with a tail flue body. A high-temperature superheater, lower-temperature superheaters, economizers and two sets of air preheaters are sequentially mounted in the tail flue body. Each economizer is formed by spiral fin pipes. A cold air inlet is formed in the lower air preheater. A hot air outlet is formed in the upper air preheater.

The invention discloses a structure increasing cast aluminum rotor iron core ventilation area so that a problem that existing cast aluminum rotor iron cores are poor in heat-radiating effect is solved. The structure comprises multiple stator iron core segments which are arranged in a spacing way and multiple rotor iron core segments which are arranged in the spacing way. The stator iron core segments and the rotor iron core segments are oppositely arranged. One side, which is away from the stator iron cores, of the rotor iron cores is provided with air inlet channels. The structure is characterized in that width of each radial air channel between the rotor iron core segments is greater than width of each radial air channel between the stator iron core segments. Advantages of the air path structure of a conventional symmetrical radial ventilation motor are maintained, and width of the rotor radial air channels aligning with the stator iron core air channels is increased under the situation of maintaining effective length of the stator iron cores and the number of the radial air channels so that motor performance parameters and force and energy indexes are profoundly guaranteed.

The invention relates to the technical field of electrical connection, in particular to a UK wiring terminal and a manufacturing method thereof. The UK wiring terminal comprises a shell and an electricity receiving block, and the shell comprises a framework body and a filling body; and the framework body is of a frame type structure. The filling body is arranged between the frameworks of the framework body, and the framework body and the filling body are prepared through the steps of injection molding, pressure maintaining, filling and hot melting. As the UK wiring terminals are fixed on the guide rail in use, the application environment of the UK wiring terminals has corresponding requirements on aging and insulating properties of the UK wiring terminals, and the UK wiring terminals are widely applied to a circuit system, so that the cost is reduced and the reliable service life of the UK wiring terminals can be damaged by using a certain proportion of returned materials for manufacturing; therefore, the framework body formed by new material injection molding is arranged to form the shell frame, and the returned material is supplemented, injected and filled between the frames of the shell, so that the effective service life of performance parameters in use is maintained, the cost of raw material expenditure is reduced, and the competitiveness of UK wiring terminal products isimproved.
