In a power unit comprising an engine (13) and an HST (24) which are formed into an integral body, a lubricating oil for use in the engine and an operating oil of the HST (24) are commonized. After being cooled, the common oil is fed from the side of the engine (13) to the HST (24). Such arrangement suppresses the drop in viscosity of the common oil and prevents the drop in efficiency and the occurrence of seizing on the side of the HST (24).

The present invention discloses a method for continuously producing chloroparaffine. Said method includes the following steps: making paraffin oil be passed through paraffin oil inlet and continuously fed into reactor; making chlorine gas be passed through circulation material and chlorine gas feeding device and fed into reactor from bottom portion of said reactor; under the catalysis of UV light making them implement chlorination reaction; making reaction product of the prior-stage be fed into reactor of next-stage to make continuous reaction, making the reaction product of the last reactor be fed into subsequent work-shop section to make refinement; making the reaction product overflowed from upper portion of reactor be fed into inlet of external cooling device, cooled, then passed through circulating pump, conveyed and premixed with chlorine gas, then fed into reactor.

The invention discloses a frame metal touch switch panel. A metal frame is fixedly connected to one side of the main body of the touch switch panel, and a wire management box is fixedly connected to the bottom end of the back of the main body of the touch switch panel. The inner side of the wire management box is uniformly provided with a wire management groove, and one side of the wire management box is fixedly connected with a limit cover at one end of the wire management groove, and both ends of the wire management groove are provided with a limit chute. The wire management trough, the sliding plate and the wire take-up hook store the wires in the wire management groove after the wiring is completed, and under the action of the limit cover and the return spring, the wires of different lengths are stored in the wire management box to avoid contact After the control switch panel is installed, the wires appear to be wound and scrolled, so that the wires are independently distributed, which effectively prevents the short circuit of one of the wires and burns all the surrounding wires, and improves the safety of the touch switch panel. safety performance.

The invention discloses a sleeve type continuous calcining vertical kiln. An annular kiln cavity is formed by the encircling of an inner barrel and an outer barrel which are sleeved together in a kiln body; the annular kiln cavity is provided with a preheating area, a calcining area and a cooling area in sequence from top to bottom; the barrel wall of the inner barrel is provided with a pluralityof ventilation holes for communicating the annular kiln cavity with the inner cavity of the inner barrel; the periphery of the outer barrel is covered with a barrel-shaped kiln shell; a peripheral air channel is arranged between the inner wall face of the barrel-shaped kiln shell and the outer wall face of the outer barrel in an encircling manner; ventilation holes for communicating the annular kiln cavity with the peripheral air channel are distributed on the barrel wall of the outer barrel; radial isolation structures are distributed at intervals in the inner cavity of the inner barrel and the periphery air channel in a staggered way along the axial direction of the kiln body; and a fuel feeding device communicated with the calcining area in the annular kiln cavity is arranged on the upper part of the kiln shell. The vertical kiln has a simple structure and a good energy-saving effect; and calcination of powdery or particulate small-diameter stone raw materials is realized, waste ofraw materials is avoided, meanwhile, the operation of the kiln is simplified, and the fuel consumption is lowered.

An overcurrent protection circuit, the overcurrent protection circuit comprising: a voltage conversion unit (110), a reference voltage generation unit (120), a voltage comparison unit (130), and a switch unit (140); the voltage conversion unit (110) is used for receiving an input voltage and converting the input voltage so as to generate a modulation voltage; the reference voltage generation unit (120) is used for generating a reference voltage which is used for comparison with the modulation voltage; the voltage comparison unit (130) is electrically connected to the voltage conversion unit (110) and the reference voltage generation unit (120), respectively, and is used for comparing the modulation voltage with the reference voltage so as to generate a corresponding control signal; the switch unit (140) is electrically connected to the voltage comparison unit (130) and the voltage conversion unit (110), respectively, and is used for determining, according to the control signal, whether to output the modulation voltage.

With a hemispherical large soup pot boil soup food in great quantities, in the form of heat medium oil evenly heating the inner pot of soup pot and maintain a prescribed heating temperature, recycle what happens when heat medium oil vaporizing gas rotary laminated large saucepan. Hemispherical large is its main technical points, by heating pot body inner pan pan ontology, between the outer wall of the lining of the cooking pot, and can be injected into heat medium oil formed by the interlining cavity, the interlining cavity at the upper side of the installed switch and through the vent, at the other side of the interlining cavity at the upper part of the installed so that they can inject heat medium oil discharge heat medium oil vaporizing gas and heat medium oil pipelines, sensing interlining cavity heat medium oil temperature of the thermal probe, connected to the hot medium oil pipeline and equipped with the burner blower air vents can inhale vaporized gas vaporizing gas pipeline, as well as the heating of the heat medium oil to the specified temperature of the installed heating accessories and so on a series of parts.
