The invention relates to a hand-held power tool (12), in particular to a screwing device (10), comprising a control device (32) for controlling and / or regulating the tool movement of a tool holder (30) and / or of a tool. According to the invention, the hand-held power tool (12) has an interface (40) for communicating with an external adjustment device (42), said interface (40) being connected to the control device (32), in such a way that signals may be transmitted, for the parameterisation of at least one tool movement sequence comprising a plurality of sequentially-progressing tool movements. The invention also relates to a corresponding method.

The method determines whether soot loading of a gas particulate filter (GPF) requires regeneration. If it does, the temperature of the GPF is read to determine whether it is sufficiently high to achieve particulate (soot) burning. If it is not, an engine control module is commanded to adjust variables such as spark timing, fuel injection timing and valve timing. If the temperature of the particulate filter is sufficiently high that regeneration can occur, other variables may be adjusted such as leaning the air / fuel mixture, retarding the spark timing, the fuel injection and valve timing. Because the latter adjustments may limit or reduce either engine speed or power, messages in a message center are provided indicating, first, that the driver should continue driving for GPF regeneration and, subsequently, under certain conditions, that the engine power has been reduced. Operation of the motor vehicle proceeds until, based upon sensed conditions or pre-determined experimental or empirical data, the filter has been regenerated.

The present invention relates to an energy-saving short-circuit impact-resistant offshore wind power transformer, which includes: a housing for accommodating the main body of the transformer; a shock absorbing mechanism arranged at the bottom of the housing for maintaining the balance of the transformer; the control unit, They are respectively connected with the shock absorbing mechanism and the wind speed sensor to receive the data measured by the position sensor, the wind speed sensor and the weight sensor, and calculate the balance degree of the transformer according to the height of the bearing platform, and the control unit according to Compare the transformer balance degree with the preset value and judge whether the transformer balance degree meets the standard according to the result, and when the transformer balance degree does not meet the standard, correct the operating parameters of the shock absorbing device according to the actual transformer balance degree, and control the The unit adjusts the parameters of the damping device, while effectively increasing the anti-shock performance of the transformer, it can effectively avoid the occurrence of short circuits and accidents, thereby effectively increasing the safety of the transformer.

The invention discloses a dust removing system pipe network resistance balance evaluation and debugging method. Benchmarking comparison is conducted between dust removing system pipe network operating parameters and pipe network original design parameters on the basis of dust removing system pipe network operating parameter testing, so that evaluation is conducted on resistance balance condition of a dust removing system pipe network, and dust removing system pipe network resistance reaches balance again through field debugging of the dust removing system pipe network resistance, the fact that a dust removing system effectively trap and gather dust produced by all dust absorption points is guaranteed, and work environment is purified. The dust removing system pipe network resistance balance evaluation and debugging method not only provides reliable technical parameters and a theoretical basis for manufacturer removing system management and enables production run, management, maintenance and repair to be conducted with purposes, but also has a theoretical and practical guiding significance for dust removing system pipe network field debugging and major-medium maintenance and repairing. The dust removing system pipe network resistance balance evaluation and debugging method can guarantee the fact that the dust removing system pipe network operating parameters are adjusted under the circumstance that cost is low and production is not influenced, and enables the operating parameters to reach design demands. The problem which only can be solved through major maintenance and repairing to an original dust removing system is solved, and fund is saved.

The invention discloses a method and a system for hydrogenation treatment of residual oil in a fixed bed which can be rotated in series. The method comprises: the residual oil hydrotreating is provided with a hydrotreating reaction zone and a hydrotreating reaction zone connected in series, and the hydrotreating reaction zone includes N hydrotreating reactors; wherein the first to The N-1th hydrogenation pretreatment reactors are successively connected in series and used as N-1 online hydrogenation pretreatment reactors, and the Nth one is used as an off-line hydrogenation pretreatment reactor; when the first hydrogenation pretreatment reaction When the pressure drop in the reactor rises to the design upper limit of the pressure drop or the catalyst activity is lower than the requirement, the first hydrogenation pretreatment reactor is switched out, and the Nth hydrogenation pretreatment reactor is used as the N‑1 online hydrogenation pretreatment Reactor; switching in the above manner can realize uninterrupted N‑1 stage hydrogenation pretreatment reaction. The method can improve the utilization efficiency of the main catalyst and the stability of the device operation, and greatly prolong the operation time of the hydrogenation reactor.

The invention relates to a control method, a control system, and an air conditioner for adjusting frosting of an air conditioner, wherein the control method for adjusting frosting of an air conditioner includes: when the air conditioner is in a heating mode, detecting the outdoor ambient temperature T 1 ;Judging the outdoor ambient temperature T 1 The relationship with the first temperature preset value; when the outdoor ambient temperature T 1 When the temperature is greater than the first preset temperature, the air conditioner enters into a frosting adjustment mode. In the present invention, by setting the outdoor ambient temperature to meet certain conditions, the air conditioner does not stop for heating operation, and the air conditioner enters the heating defrost or heating suppression frost mode, so as to prevent the frost layer from weakening the heating capacity of the air conditioner and avoid traditional refrigeration defrosting In this way, because the compressor accumulates too much refrigerant, it will affect the reliability and life of the compressor; defrosting or frost suppression during the heating process will not cause a decrease in the indoor temperature, improve the comfort of the room, and improve user experience.

The invention discloses a method and system for hydrogenation treatment of residual oil in a fixed bed which can be rotated. In this method, the first hydrogenation pretreatment reactor is connected in series with the second hydrogenation pretreatment reactor as an online hydrogenation pretreatment reactor, when the pressure drop in the first hydrogenation pretreatment reactor rises to the pressure drop design upper limit Or when the catalyst activity is lower than the requirement, cut out the first hydrogenation pretreatment reactor and as off-line hydrogenation pretreatment reactor, then press the second hydrogenation pretreatment reactor and the third hydrogenation pretreatment reactor in parallel, The third hydrogenation pretreatment reactor is connected in parallel with the first hydrogenation pretreatment reactor, and the sequence of the first hydrogenation pretreatment reactor and the second hydrogenation pretreatment reactor being connected in series is switched, thereby realizing that there are two hydrogenation pretreatment reactors The treatment reactors are online at the same time, and through multiple cycle rotations, uninterrupted hydrogenation pretreatment reactions can be realized.
