The invention discloses a regulation method and device. The regulation method includes: acquiring M current performance data from M servers in a cabinet, wherein each current performance datum in the M current performance data at least includes current utilization information in main controller performance data of the main controller of the M servers, and M is an integer greater than or equal to 1; determining at least one adjustment parameter used for adjusting air supply equipment according to the M current performance data; according to the at least one adjustment parameter, controlling current air supplying mode of the air supply equipment so as to enable the current air supplying mode to be matched with M current utilization of the M main controllers.

The invention particularly relates to a control circuit and a control method of a flyback active clamp and an asymmetrical half-bridge switching converter. As far as the circuit solution is concerned, the present invention provides a flyback control circuit, including an integrated control circuit for controlling the switch tube and the clamp tube, and the integrated control circuit includes a drive unit for the switch tube, a drive unit for the clamp tube, and an off-hold drive When the unit is light-loaded or no-loaded, the sum of the turn-on time of the switch tube, the turn-on time of the clamp tube and the dead time between them forms a single cycle, and the duration of the single cycle is a fixed value. The turn-on time of the switch tube It has a complementary relationship with the turn-on time of the clamp tube in a single cycle; the time of a single cycle and the time of keeping it off constitute the total working cycle. Compared with the prior art, the present invention improves light-load efficiency and reduces no-load power consumption under the condition of ensuring the efficiency and EMI advantages of traditional circuits under light-load and above loads.

The invention relates to a biconical high consistency refiner which comprises a machine frame, a main shaft, a refining chamber base, the middle portion of a refining chamber, and a refining chamber cover, wherein a bearing seat is horizontally and fixedly installed on the machine frame, the refining chamber cover, the middle portion of the refining chamber, and the refining chamber base are formed coaxially, the closed refining chamber is defined by the refining chamber cover, the middle portion of the refining chamber, and the refining chamber base, a biconical stator is fixedly installed on the main shaft arranged inside the middle portion of the refining chamber coaxially, a biconical rotor is installed in an inner gap of the biconical stator, and three refiner areas, namely two conical refiner areas arranged in a mirror symmetry mode and a cylindrical refiner area connected in the middle, are formed by the biconical rotor and the biconical stator. The refining chamber cover and the middle portion of the refining chamber can be opened in the radial direction by means of a mechanical arm and a hinge with the refining chamber base as the basis, so that refining chamber maintenance and adhesive disc replacement are facilitated. Under the condition that the effective refining area stays the same, the no-load power consumption of the biconical high consistency refiner is much lower than that of a single-tray high consistency refiner and a three-tray high consistency refiner. Under the condition that the axial length stays the same, the radial size and no-load power consumption of the biconical high consistency refiner are smaller than those of a conical high consistency refiner.
