The invention discloses a kernel rotor device of an exhaust-gas turbocharger, comprising a middle casing, a thrust sleeve, a thrust bearing, an oil baffle, and a shaft gland, wherein a blade wheel is arranged on a turbine shaft on one end of the shaft gland, the middle casing on the one end of the blade wheel is provided with a chamber, a sealing ring sleeve base is arranged in the chamber, and the sealing ring sleeve base comprises a ring-shaped component which is sealed with the inner walls of the chamber and a lantern ring which is dynamically sealed by the shaft gland and is arranged on the turbine shaft. A ring-shaped connecting member is fixedly connected between the ring-shaped component and the lantern ring, one lateral side of the ring-shaped connecting member which faces the blade wheel is provided with an arc-shaped end face which is relative to the shape of the blade wheel. The original connection between a linking disk and the middle casing is changed into the connection of the middle casing and the sealing ring sleeve to remove the linking disk with large size, thereby avoiding deformation of the product. The original projection sealing is changed into notch sealing to enlarge the oil return space of the product, and the original screw pressing is changed into a circlip pressing, thereby providing conveniences for assembly, easily adopting an automatic assembly line, and reducing the cost of the product.

The purpose of the present invention is to provide a slide part which is configured so as to control the streak-like flow of fluid caused by cavitation occurring in a recessed portion such as a dimple in a slide surface, thereby being capable of preventing the leakage of the fluid irrespective of the magnitude of the difference between pressures at the inner and outer peripheries of the slide surface. A slide part is characterized in that a dimple is provided in the slide surface of one of a pair of slide parts which slide relative to each other, and that a groove having directivity is formed in the region of the dimple where cavitation is formed.

The present description relates to a hybrid environment sensor configured to measure a concentration of a particulate matter and gas element and concentration. More particularly, a hybrid environment sensor that can reduce the size of the entire environment sensor and substantially reduce the total power consumption through arranging a gas sensor configured to measure gas element and concentration included in the air in a housing unit that measures concentration of the particulate matter.

The invention relates to an ore crushing and conveying mechanism for mining. The ore crushing and conveying mechanism comprises supporting posts and a water tank, wherein a crushing tank is arranged on the upper ends of the right sides of the supporting posts; a material outlet is fixedly formed in the bottom part of the crushing tank; a second case is arranged on the lower end of the right side of the crushing tank; a second motor is arranged at the inner part of the second case; a belt is embedded at the left side of the second motor. The ore crushing and conveying mechanism disclosed by theinvention has the beneficial effects that through a first case, a first motor can be protected during an ore crushing process, the first motor can be prevented from being crushed and broken, ores entering the inner part of the crushing tank can be blocked, uncrushed ores can be in full contact with a first crushing post and a second crushing post, and the crushing efficiency of the ores can be quickened; a gap is reserved between the first case and the crushing tank, so that crushed ores can automatically drop down, the crushing tank requires not to be manually opened for conveying the crushed ores, certain labor is saved, and the convenience of the ore crushing and conveying mechanism is increased.

The invention discloses small-scale purification equipment for biogas. The equipment comprises a main body, and a purification device is arranged in the main body; the purification device includes a purification cavity arranged on the inner left side of the main body, an extrusion plate capable of sliding left and right is arranged in the purification cavity, a filter membrane cavity is arranged in the left end surface of the extrusion plate, and a semi-permeable membrane is fixedly arranged in the filter membrane cavity; and the left end of the upper wall of the purification cavity communicates with an air inlet channel having an upward opening, the left end of the lower wall of the purification cavity communicates with a methane channel, and when the extrusion plate moves from left to right, the biogas is sucked into the purification cavity through the air inlet channel. According to the equipment, flow of the biogas is accelerated by sucking air, methane is quickly separated from the rest of waste gas by compressing the gas, the methane and the waste gas are discharged respectively, a gas flow direction is controlled by controlling opening and closing of channels for biogas inflow, methane outflow and waste-gas outflow, so that the backflow phenomenon of masonry is avoided.

The invention provides a stamping system for the upper cover of a battery pack of a new energy vehicle, which includes a stretching station, a trimming station, a flanging shaping station and a punching station arranged in sequence, and the four stations are respectively arranged correspondingly There are stretching dies, trimming dies, flanging shaping dies and punching dies; during production, stretch forming, outer edge punching and trimming, outer edge bending and flanging, and punching are performed on the sheet to be processed in sequence; The outer ring of the die of the drawing die is provided with a first bead structure of unequal height, the outer ring of the punch of the drawing die is provided with a second bead structure, and the first bead structure is the same as the first bead structure The above-mentioned second bead structure cooperates to control the material flow direction to prevent cracking and wrinkling; a stamping system for the upper cover of a new energy vehicle battery pack provided by the present invention adopts four stations and corresponding four molds, which can The product is stamped and formed at one time, and its airtightness is good, which can meet the airtightness requirements of the product.

The invention discloses a flow guiding umbrella, comprising an umbrella skeleton and an umbrella cloth; the umbrella further comprises a rainwater flow guiding mechanism; the rainwater flow guiding mechanism is moveably connected to the periphery of the umbrella skeleton, and forms an included angle with the umbrella skeleton; the umbrella cloth is coated on the rainwater flow guiding mechanism, and a single rainwater outlet is formed at the included angle, thus the rainwater fallen on the umbrella is only flowed from the outlet. The flow guiding umbrella is simple in structure and easy to control, thus the sunshade function of an ordinary sunshade and the rainproof function of an ordinary umbrella can be realized; meanwhile, the umbrella can control the rainwater flowing direction and guide rainwater to a fixed outlet.
