This invention discloses a method for self-learning the clutch of an AMT (Automated Manual Transmission) in commercial vehicles, specifically including the following steps: Step 1: Determine whether the current vehicle meets the self-learning conditions; if so, proceed to Step 2; Step 2: Clutch self-learning: After activating clutch self-learning, the clutch will perform two rounds of disengagement and engagement; Step 3: After the clutch performs two disengagement and engagement actions, the learned parameters are stored in the TCU (Tracking Control Unit), completing one clutch self-learning cycle; Step 4: Repeat the above process to complete multiple clutch self-learning cycles. The method of this invention defines the complete disengagement point and the first, second, and third contact points by using the input shaft speed as a threshold, resulting in higher recognition accuracy and a simpler and more efficient TCU judgment and calculation logic.

The present invention relates to the technical field of grain depot ventilation, and specifically discloses an energy-saving grain depot ventilation and dust removal adjustment system, including an equipment base, the upper surface of which is fixedly connected with a bracket one and a bracket two, a centrifugal fan is fixedly installed on the top of the bracket one, a cyclone separator is fixedly installed on the top of the bracket two, and a water tank is also fixedly connected to the upper surface of the equipment base, and a material receiving bucket is arranged directly below the cyclone separator; by driving the movable seat to rotate, the connection between the centrifugal fan and the exhaust duct and the cyclone separator can be controlled, and the sealing component can also be regulated. When the centrifugal fan is connected to the cyclone separator, air is inletted radially and exhausted axially, meeting the demand for rapid ventilation of a large space; when connected to the exhaust duct, air is inletted axially and exhausted radially, which is suitable for the situation where the air duct is long and has large resistance. Both modes can remove dust through the cyclone separator, which is energy-saving and reduces costs. Compared with the existing technology, the integrated design has obvious advantages, saving costs and space, and reducing energy consumption.

The invention relates to the technical field of warehouse controlled atmosphere insect killing, in particular to a low-temperature controlled atmosphere insect killing device and method.The low-temperature controlled atmosphere insect killing device comprises a nitrogen making device, a mixing heat insulation chamber and a sealed warehouse which are sequentially connected in the air inlet direction, and the mixing heat insulation chamber is connected with a dry ice feeder; temperature control valves are arranged at the discharging end of the dry ice feeder and the gas outlet end of the nitrogen making device respectively, the feeding amount of dry ice and the gas inlet amount of nitrogen are controlled through the temperature control valves, the nitrogen is cooled through the dry ice, and the dry ice and the nitrogen form mixed modified atmosphere gas with the temperature lower than 10 DEG C and then enter the sealed warehouse; the oxygen concentration in the sealed warehouse is reduced to be smaller than or equal to 2% through the introduced mixed modified atmosphere gas, and the low-oxygen environment is maintained within 15 days. The low-oxygen environment formed by low-temperature and high-concentration nitrogen and carbon dioxide has a synergistic killing effect on grain or tobacco insect pests in the closed warehouse, and the treatment time of controlled atmosphere pest and disease killing is remarkably shortened.

The invention relates to the technical field of fuel cell forklifts, and discloses a replaceable hydrogen supply device and a fuel cell forklift, the replaceable hydrogen supply device comprises a rack and a box body detachably mounted on the rack; at least one hydrogen bottle is arranged in the box body, and the hydrogen bottle is used for providing hydrogen for the fuel cell system; the two ends of the box body extend upwards to be provided with hanging plates respectively, a plurality of hanging rings are arranged on the sides, deviating from each other, of the two hanging plates, and the hanging rings are used for hoisting the box body. The multiple hydrogen cylinders are arranged in the box body, other hydrogen cylinders in the box body can be replaced in time after gas of one hydrogen cylinder is used up, the gas exchange time is greatly saved, the working efficiency of the fuel cell forklift is improved, on the other hand, the box body only needs to be lifted away from the fuel cell forklift through the lifting ring, then the box body is replaced with a new box body, and the cost is reduced. And the fuel cell forklift can be immediately put into use, so that the problem of difficulty in ventilation of the fuel cell forklift at present is solved.

The utility model discloses a damp-proof intelligent cabinet for intelligent home furnishing, and relates to the technical field of intelligent home furnishing. The moisture-proof cabinet comprises a cabinet body, a cabinet door is hinged to the outer surface of the cabinet body, a pull rod is fixedly connected to the outer surface of the cabinet door, a placing table is fixedly connected to the interior of the cabinet body, and a moisture-proof device is arranged in the cabinet body; the moisture-proof device comprises a three-phase asynchronous motor, the three-phase asynchronous motor is fixedly connected to the cabinet, and an output shaft of the three-phase asynchronous motor is fixedly connected with a rotating rod. The rotating force of the rotating rod driven by the three-phase asynchronous motor is matched with the three-phase asynchronous motor, the rotating rod, the fan blades, the heating block, the air extracting pump, the strip-shaped air conveying pipe, the air outlet plate and other components in the moisture-proof device, so that the moisture-proof effect of the air outlet plate and the heating block is achieved, and therefore the cabinet can be placed in a humid environment for a long time; the interior of the cabinet is not moist, the moistureproof effect is achieved, the moistureproof time is shortened, and the working efficiency is improved.

This invention provides an electrostatic chuck and semiconductor processing equipment. The electrostatic chuck includes an annular air passage, a main air passage group, and a secondary air passage group. The annular air passage is located near the edge of the upper surface of the chuck body, defining a heat exchange area within it. The main air passage group surrounds a central air inlet, and the secondary air passage group surrounds the main air passage group. The main air passage group is connected to both the central air inlet and the secondary air passage group, and is configured to increase the speed at which the back-blown gas flowing from the central air inlet is delivered to the secondary air passage group. The secondary air passage group is connected to both the main air passage group and the annular air passage, and is configured to ensure uniform distribution of the back-blown gas at different locations within the heat exchange area. The electrostatic chuck and semiconductor processing equipment provided by this invention can effectively shorten the back-blown gas passage time while ensuring the stability and uniformity of the back-blown gas pressure, thereby increasing equipment productivity.
