An analog buffer for buffering an input voltage to an output line is provided. The analog buffer includes a constant current source and a comparator. The constant current source supplies a constant current to the output line, and the comparator compares a voltage charged on the output line with the input voltage to turn-off the constant current source if it is determined that the voltage charged on the output line corresponding to the input voltage is buffered to the output line.

The invention discloses a petrol-electric self-hybrid power propelling system applied to inland water transport ships. Storage batteries are connected with a controller through a power manager, the controller is connected with a wheel house control console and a driver connected with a motor, and a first belt wheel is arranged on the shaft of the motor. The controller is connected with a diesel accelerator servo motor driver connected with a diesel accelerator servo motor, a second belt wheel is arranged on a main diesel through a gearbox, and the first belt wheel is in linkage with the second belt wheel through a cog belt. The cog belt is in linkage with the shaft of the motor through the first belt wheel and is in linkage with a universal coupling through the second belt wheel, and the universal coupling is in linage with an input end of a ship propeller. In a normal state, the storage batteries output electric energy through the motor to drive the ship propeller. The main diesel and the motor drive the ship propeller jointly when the storage batteries cannot meet the requirement of the headway of the ships. When the storage batteries lack electric power, the main diesel provides power for the ship propeller after starting, and the motor serves as a power generator to charge the storage batteries.

The invention relates to a pendulum-type balance intelligent control pumping unit, which is mainly characterized in that the frame is a cantilever structure extending from the top; The main and passive reversing wheels are composed of main and passive reversing wheels. The main and passive reversing wheels are connected by reversing ropes. The passive reversing wheels are fixed with suspension ropes. Connected and linked, the motor is connected with a motor vector control cabinet, the control cabinet is connected with an intelligent control device through a data bus, and the intelligent control device is connected with a flow sensor for monitoring the swabbing flow through a signal transmission line. The pumping unit can automatically control the strokes and strokes of the pumping unit according to the downhole conditions, improve the motor efficiency, reduce labor intensity, and has the advantages of simple structure, high balance, reliable performance, energy saving, lower production and use costs, etc. advantage.

The invention discloses operation modes and a structure of a heat-circulation heat pump drying unit. The structure is characterized in that the drying unit comprises a heat recovery air duct which forms a sealed air flow circulation loop with the inner cavity of the drying oven, an evaporator is installed in the air duct, and an air regulator for regulating and controlling the air flowing through the evaporator is arranged in the unit. The operation modes are a heating mode and a heat-circulation dehumidification mode. In the early operation stage of the unit, the heating mode is started, the heat pump system absorbs heat from the atmosphere, so that the air in the drying oven is heated to achieve the preset temperature; and then, the unit operates the heat-circulation dehumidification mode, the high-temperature high-humidity gas in the drying oven flows through the evaporator in the air duct to be cooled and dehumidified and then flows back to the drying oven, the sensible heat and latent heat absorbed by the evaporator are released into the drying oven by a condenser, and the air regulator enables the ratio of the condensation air quantity to evaporation air quantity to be greater than 2 and controls the inlet / outlet air temperature difference of the evaporator to be 10-25 DEG C. The unit has the advantages of high average COP and high latent heat ratio in the heat absorbed by the evaporator; and the dehydrating amount per kilowatt-hour is 5 kilograms or above, so that the efficiency is enhanced by 70-130% as compared with the conventional heat pump drying.
