The invention relates to a compressor system (10) comprising a compressor (12) for supplying compressed air to a utility vehicle (14) that has a driving engine (18) with a turbocharger (16). Air that is pre-compressed by the turbocharger (16) can be sucked in by the compressor (12) via a first air supply pipe (20). According to the invention, ambient air that is not pre-compressed can be sucked in by the compressor (12) via a second air supply pipe (12). The invention further relates to a method for controlling a compressor system (10) comprising a compressor (12) for supplying compressed air to a utility vehicle (14) that has a driving engine (18) with a turbocharger (16).

The invention discloses a hand-pushed transmission mechanical vehicle, and relates to the field of industrial machinery. The hand-pushed transmission mechanical vehicle comprises an object carrier. The object carrier comprises a bottom plate, a front side plate, a rear side plate, a left side plate and a right side plate. Rollers are connected with the bottom plate, a push rod is arranged on the right side plate, the area of the bottom plate is 1-1.2 square meters, the left side plate and the right side plate are both hinged to the bottom plate, sliding rails are arranged on the front side plate and the rear side plate respectively, the left side plate and the right side plate are both connected with the sliding rails through balls respectively, and gravity alarms are arranged in the rollers. The push rod is connected with the right side plate in a clamping mode, the object carrier is detachable, the sliding rails can change capacity of the object carrier, and the push rod also can be detached from the right side plate. When the hand-pushed transmission mechanical vehicle is not used, the whole hand-pushed transmission mechanical vehicle can be detached and stacked to be stored, only plane space is occupied, indoor space is greatly saved, the gravity alarms can guarantee that the vehicle can not be overloaded, the hand-pushed transmission mechanical vehicle is prevented from being damaged, and the hand-pushed transmission mechanical vehicle is reasonable in structure, practical, convenient to use, and suitable for being used and popularized.

The invention discloses a hydraulic lifting control system for a double-tire lifting axle. The hydraulic lifting control system for the double-tire lifting axle comprises an oil tank (12), a filter screen (13), a motor (14), an oil pump (15), a check valve (16), a reversing valve (17), a one-way throttle valve (18), a lifting oil cylinder (7), an overflow valve (19) and an oil pipe (26), wherein the motor (14) is connected with the oil pump (15); the filter screen (13) is arranged between the oil tank (12) and the oil pump (15); the check valve (16) and the overflow valve (19) are respectively arranged on the outlet of the oil pump (15); the one-way throttle valve (18) is arranged on the rod cavity oil path of the lifting oil cylinder (7); the oil pipe (26) between the one-way throttle valve (18) and the rodless cavity of the lifting oil cylinder (7) is provided with a hydraulic load sensing valve (20); the valve core (31) of the hydraulic load sensing valve (20) is connected with a connecting rod (23) fixedly arranged on a drive axle by a control arm (25). The hydraulic lifting control system for the double-tire lifting axle has a novel design, and the finished automobile driving and braking performance can be improved.

The invention discloses a computer for circulating cooling and cooling, which belongs to the field of electronics, and comprises a backup water tank, a main water tank, a solenoid valve F1, a solenoid valve F2, a water pump M1, a speed-regulating water pump M2, a solenoid valve F3, a flow rate sensor LL1, and a temperature sensor T1 , solenoid valve F4, cooling pipe, control board and USB interface, solve the technical problem that the water tank is too large in the traditional technology and cannot automatically adjust the power, the invention divides the water tank into two, and automatically adjusts whether to use a spare water tank according to the temperature The cooling water reduces the volume of a single water tank, the water tanks can be installed separately, and the space requirement for the computer case is small. The invention automatically adjusts the output power of the water cooling system, and automatically adjusts the output power of the water pump according to the output power of the computer's own power supply. , so that the output of the computer power supply is not overloaded.

The invention discloses a control algorithm for regulating paddle screw pitch and host revolving speed matching during the startup of a ship. The control algorithm comprises the following steps: (1) equally dividing n and H to obtain n present and H present; (2) obtaining thrust P according to a formula; (3) obtaining the current output power W of the ship according to a formula; (4) based on the obtained thrust P and current output power W of the ship, obtaining a control criterion J1 according to a formula; (5) obtaining distance J2 between a target and the current control target according to the formula; and (6) obtaining multiple groups of J1[i][j] according to a formula, substituting n[i] and H[j] into a formula to obtain the minimum J2[i][j], wherein the n[i] and the H[j] are target revolving speed n and target screw pitch H. The control algorithm has the beneficial effect that a host can reach the maximum output power along the optimal path and does not work in an overload mode during the startup of the ship according to the algorithm, and meanwhile, the maximum thrust output is guaranteed.
