Volute tongue structure of fan for range hood

The invention relates to a volute tongue structure of a fan for a range hood. An inner concave surface is formed on one side, facing an air outlet of the fan, of a volute tongue. The volute tongue structure is characterized in that the volute tongue comprises a front disk, a central disk and a rear disk, wherein the side parts, facing to the air outlet of the fan, of the front disk, the central disk and the rear disk wholly form the inner concave surface, the front disk further extends to the bottom left to form a front side deep tongue on the basis of the inner concave surface, the rear disk further extends to the bottom left to form a rear side deep tongue on the basis of the inner concave surface, and the central disk is continuously and inwards concave to form a central short tongue on the basis of the inner concave surface. Compared with the prior art, the volute tongue structure disclosed by the invention has the advantages that the volute tongue forms the front side deep tongue, the rear side deep tongue and the central short tongue, the gap between the front disk, the rear disk and a vane wheel is smaller, and the gap between the central disk and the vane wheel is larger, so that the speed at which front and back air currents flow out cannot be much lower than the speed at which the central air current flows out, the whirlpool caused by a low speed of two sides and high speed of the center is eliminated, and further the whole efficiency of the fan is improved.

Swash plate type reciprocating piston compressor

The invention relates to a swash plate type reciprocating piston compressor, and belongs to the technical field of compressors. The swash plate type reciprocating piston compressor comprises a drive shaft, a master swash plate, a slave swash plate, cylinders, pistons, connecting rods and the like; sliding blocks and the connecting rods are compelled to be closely attached to steel balls and sliding shoes by using a reset mechanism; the steel balls and the sliding shoes are further compelled to be propped against the slave swash plate; meanwhile, the slave swash plate is compelled to be propped against the master swash plate, so that a gap of a matching pair can be reduced and even eliminated; the swash plate type reciprocating piston still has a continuous positive effect even though parts are abraded, so the mechanical noise of the compressor is reduced; by a layout form of a top cooling fan, cooling air can be directly blown to a cylinder head of the compressor to effectively reduce the temperature of the parts, so that gap change quantity caused by thermal deformation is reduced, and the mechanical noise is indirectly reduced; and a guide rod or guide sleeve structure is used for restraining the connecting rods to do linear motion, and the swinging amplitude of the connecting rod is effectively reduced, so that slapping of the pistons on reversing of the cylinder is reduced, and the mechanical noise of the compressor is further reduced.

Freeze and shock proof turnout

InactiveCN101851881ASmooth connectionReduce gapRail switchesLight railHigh intensity
The invention relates to a freeze and shock proof turnout which comprises a base, a ram, a straightaway transition rail, a turnout transition rail, a drive device and a ram locking device, wherein the straightaway transition rail and the turnout transition rail are arranged on the ram. The freeze and shock proof turnout is characterized in that the straightaway transition rail and the turnout transition rail which are arranged on the ram in parallel move on the base through the ram to finish turnout conversion, and the ram is locked through a positioning device. The freeze and shock proof turnout has the advantages that because the connection between the transition rails and steel rail joints at both ends of the transition rails is smooth and has small gaps, clearance spaces in medium and low speed turnouts at present are eliminated; a high-strength precise positioning and locking device is adopted, which ensures that a train is stable and safe during passing the turnout, and impact shocks and noise between wheels and rails are greatly reduced, thus the train can quickly and safely pass the turnout without reducing the speed; and meanwhile, the drive device is arranged in the ram to thoroughly eliminate influences caused by snow and ice in winter on the turnout, thus a snow and ice thawing device does not need to be arranged in the turnout so as to reduce the investment, save energy and protect the environment. The freeze and shock proof turnout is widely applied to medium and low speed railways and urban metro and light rail routes.
