The invention provides a permanent magnet suspension train track system, specifically discloses a permanent magnet suspension track system, which is formed by suspension steel rails, a permanent magnet suspension track and permanent magnet suspension components, and introduces a permanent magnet suspension train system, which is formed in such a way that a train runs on the permanent magnet suspension track system, wherein the permanent magnet suspension track is arranged by using the suspension steel rails, and the permanent magnet suspension components are arranged on two sides of the suspension steel rails. The permanent magnet suspension components comprise upper magnetism collection boards, lower magnetism collection boards and suspension permanent magnets; and the magnetic gap between the permanent magnet suspension components is equal to the magnetic gaps between the left end surfaces and the right end surfaces of upper and lower yoke plates of the suspension steel rails. When the train matches with the track to run in a suspended manner, a bilateral permanent magnet linear motor efficient tractor train is formed by horizontal guide wheels, a traction coil of linear motor and a traction permanent magnet to build a safe, ultra high-speed and energy-saving novel rail transit system, wherein the horizontal guide wheels are arranged on the left side and the right side of the train, the traction coil of the linear motor is arranged on the track and the traction permanent magnet is arranged on the train. The permanent magnet suspension train track system has the advantages that automatic balancing passive suspension can be achieved, the traction driving efficiency is high, the cost is low, the permanent magnet suspension train track system is economic and energy-saving, the service life of the track is long, the permanent magnet suspension train track system is convenient to mount and adjust, and the permanent magnet suspension train track system is compatible with the existing wheel-rail track and is much safer than the existing wheel-rail track.

A housing upper part (1) for a labyrinth piston compressor comprises a cylinder barrel (2) running in the direction of a longitudinal axis (L), with a cylinder interior (2a) and a cylinder barrel exterior (2e), wherein the cylinder barrel (2) has at least one cylinder inlet opening (4, 4a, 4b) or at least one cylinder outlet opening (6, 6a, 6b) which open into the cylinder interior (2a), wherein a gas distribution housing (9a) at least partially encloses the cylinder barrel (2) in the circumferential direction with respect to the longitudinal axis (L) such that there is formed, between the gas distribution housing (9a) and at least one part section (2g) of the cylinder barrel exterior (2e) of the cylinder barrel (2), a gas distribution interior (9b), wherein the part section (2g) is axisymmetric with respect to the longitudinal axis (L), wherein the gas distribution interior (9b) is fluidically connected to the cylinder interior (2a) either via the cylinder inlet opening (4, 4a, 4b) or the cylinder outlet opening (6, 6a, 6b), and wherein the gas distribution housing (9a) comprises either a gas inlet (9) or a gas outlet (10) which is fluidically connected to the gas distribution interior (9b).

A process for performing a heterogeneously catalysed reaction in a three-phase reactor, where there is at least one liquid phase, at least one gaseous phase and at least one solid phase in the reactor and the reactor has at least two zones, with the reaction mixture being conveyed downward in zone 1, the reaction mixture being conveyed upward in zone 2, zones 1 and 2 being separated from one another by a dividing wall, and in that the ratio between the average catalyst concentrations in zone 2 and in zone 1 is greater than 2.

The invention discloses a device for rounding and slotting a housing of a water heater, belonging to a device for seaming brim of a metal sheet for rounding and seaming bent flat plate for producing the housing of the water heater. An inner die with an axial groove on the top part is horizontally arranged on an engine base; a left holding claw and a right holding claw are located on the left and right side of the inner die; the inner surface is matched with the side of the inner die; the left holding claw and the right holding claw are driven to hold or loosen the inner die by driving power of the holding claws; a slotting die driven by power of the slotting die is arranged above the inner die; and the slotting die is matched with the inner die. The technical problems of fussy processes, high labor intensity and low production efficiency caused by rounding, folding and finally seaming in processing of the housing of the existing water heater are solved.
