This invention relates to a cooling technology of motors providing a forcing circulation evaporation cooling device of a hydrogenrerator stator winding connection pipes connect the stator winding, a condenser, a pressure circulation pump and electro-hydraulic separation joints to an evcaporation cooling loop filled with evaporation cooling medium and a pressure circulation pump forcing the circulation of the evaporation cooling medium is also in the loop, every line-rod set consisting hollow heads and solid leads in the stator winding contains odd N serial line-rods, two leading out ends of the line rod set are connected with the up and down insulation lead pipes by the electro-hydaulic separation joints, several line-rod sets and a condenser constitute an independent evaporation cooling loop.

The single system one-step series pressure swing adsorption process is characterized by that in the system formed from at least three adsorption towers the raw material gas is fed into X tower to make adsorption, the outputted off-test product gas is fed into Y tower to make adsorption and obtain qualified product gas, when the adsorbable component in the product gas will exceed standard, the output can be cut off, at this time X tower adsorption is completed, then other pressure swing adsorption steps are made; at the same time the raw material gas can be fed into Y tower to make adsorption, and its outputted off-test product gas can be fed into Z tower to make adsorption and outupt qualified product gas. Said operation can be circularly made, and can further raise utilization rate of adsorbent.

The invention discloses a transmission control device based on a big data management mode, the structure comprises a lock nut, waterproof housing, Transmission control, fixed head, Variable speed seatplate, the transmission control unit is integrally mounted inside the waterproof housing in an embedded manner, the invention mainly utilizes the double-contact hair-generating mechanism, abduction positioning mechanism, co-actuated control mechanism, CONDUCTIVE MECHANISM FOR RECEIVING PROCESSING, main power output mechanism, power storage mechanism, power generating mechanism, the transmission adopts the double-contact generating mechanism, abduction positioning mechanism, the cooperating electric control mechanism cooperates with each other to carry out integral split-type fixing, when theinternal parts are damaged, the whole part can be removed and repaired only by operation of the two-contact mechanism, The energy is converted and stored by the power storage mechanism and the power generation mechanism, and the power supply of the automatic transmission is realized by the mutual cooperation of the receiving and processing conductive mechanism and the main force output mechanism.

The invention relates to a method and a device for circularly flushing carbon steel pipes of a refined cooling system. The device is characterized by comprising a cleaning box, cleaning pump inlet ball valves, a cleaning pump, a cleaning pump inlet ball valve, a high-pressure air source, a matching device, a cleaning unit, a temporary stop valve, an eccentric reducing tube and a reducing tube, wherein the cleaning box is connected to the cleaning pump through a pipe; the cleaning pump inlet ball valves are arranged on pipes at two ends of the cleaning pump; the high-pressure air source and the matching device are arranged at positions close to an inlet of a cleaning pipe, so that cleaning liquid can be subjected to matching in real time, and the flowing speed and the flowing state of the cleaning liquid are adjusted; and the cleaning unit and the temporary stop valve can be selected according to the diameters of pipes, and an optimum effect can be achieved. By the eccentric reducing tube, foreign matters are prevented from being stopped and jammed, and the circumstance that the foreign matters are stored at a joint is avoided.

The invention proposes a carbon-free steel ladle composite bottom construction process. The application of the technology not only ensures the safe use of the bottom, but also reduces the difficulty of repairing the bottom and reduces the repair cost. A carbon-free steel ladle composite bottom construction The process includes the following steps: cleaning the bottom, pouring the permanent lining castable, curing, pouring the castable for the working layer of the bottom, curing, building bricks for the working layer of the bottom, baking, using the present invention to construct the bottom, the first layer of permanent The lining castable can play the role of ensuring the safety of the bottom of the package and heat insulation. The castable of the second layer of the bottom working layer ensures the safety of the repaired bottom of the package. The third layer of carbon-free prefabricated bricks can be partially replaced and repaired. There has always been a contradiction between the safety of ladle bottom use and the bottom repair and bottom repair cost. The three-layer refractory structure of the composite bottom has solved this problem very well.

The invention discloses a four-vertical-fin load loading method which comprises the following steps: 1) installing a vertical fin frame between inner vertical fins, connecting a single lug at the upper end of the vertical fin frame to a loading cross beam, and enabling the distance between the lower end of the vertical fin frame and a rear fuselage of an aircraft to be not less than 300mm; (2) theupper end of the vertical fin frame being connected with a loading cross beam through an upper end pull plate, and the lower end of the vertical fin frame being connected with a lateral loading standcolumn through a lower end pull plate; 3) installing an actuating cylinder fixing seat at a position corresponding to the vertical fin frame; 4) installing an actuating cylinder base at a position corresponding to the lateral loading cross beam of the vertical fins; 5) connecting the actuating cylinder with a loading cross beam by using a manual hoist, adjusting the actuating loading to meet therequirement by adjusting the manual hoist, and connecting the actuating cylinder with a vertical fin end lever; and (6) repeating the steps (2) to (5) to install the vertical fin loading equipment onthe other side. The four-vertical-fin load loading method can realize bidirectional tension and compression loading of vertical fin loads, and can avoid the spatial interference problem between the loading equipment and between the loading equipment and a test piece.
