A power generating apparatus includes a rotating shaft, a hydraulic pump driven by the rotating shaft, a hydraulic motor driven by operating oil supplied from the hydraulic pump; and a generator coupled to the hydraulic motor. The apparatus further includes an oil line connected to the hydraulic pump and the hydraulic motor for circulating the operating oil between the hydraulic pump and the hydraulic motor, an oil cooler connected to the oil line for cooling the operating oil by heat exchange with a cooling medium, a cooling-medium line supplying the cooling medium to the oil cooler; a bypass line diverging from at least one of the oil line and the cooling-medium line and merging into at least one of the oil line and the cooling-medium line to bypass the oil cooler; and a flow regulating valve in at least one of the oil line and the cooling-medium line.

The invention discloses a far-infrared thermal therapy sand bed. The far-infrared thermal therapy sand bed comprises a bed head, a bed body and a bed tail, which are successively spliced together; the cross section of the bed body is in an inverted trapezoidal shape; the bed body comprises a stainless steel square-through main-beam framework, a stainless steel plate which is welded on the main-beam framework in a sealing manner and used for bearing load and transferring heat, a mica heating plate, a heat preserving and insulating plate and an outer-wall decorative layer, which are successively superimposed onto one another; both the bed head and the bed tail are respectively provided with an opening coupled with the bed body, the bed head is provided with a temperature control apparatus, and the temperature control apparatus adopts a single chip microprocessor to control the zero-crossing trigger of controllable silicon so as to control the output power and is electrically connected with the mica heating plate. The far-infrared thermal therapy sand bed is simple in structure, firm in configuration and convenient to disassemble, install, package, transport, carry and install on site. By adopting an intelligent temperature control system to be combined with the structure of the bed body, effectiveness and rapidness in heating can be achieved, the heat can be automatically and continuously preserved, and the heating and heat preserving temperature can be set according to the withstanding degree of a human body.

The invention provides a vehicle and an engine cooling system for the same. The engine cooling system comprises a cylinder water jacket, an engine oil cooler connected with the cylinder water jacket,a first water pump connected with the engine oil cooler and selectively connected with the cylinder water jacket and an EGR cooler, and a water inlet of the EGR cooler is selectively connected with the first water pump while a water outlet of the same is selectively connected with the engine oil cooler and / or the first water pump. The engine cooling system can utilize the EGR cooler to recycle heat of waste gas and supply the same to the engine oil cooler, so that temperature of engine oil in the engine oil cooler is quickly increased under low load; bypass waste gas is cooled under high load,so that negative impact on performance of a catalyst caused by the fact that high-temperature waste gas is directly discharged into the three-way catalyst is avoided.

The invention discloses preparation methods of a polybutylene alloy material. The first preparation method comprises the following steps: firstly polymerizing butane-1; and then introducing propylene to obtain a polybutylene alloy which takes polybutylene-1 as a core and polypropylene as a shell. The second method comprises the following steps: firstly polymerizing propylene; and then introducing butane-1 to obtain a polybutylene alloy which takes polypropylene as a core and polybutylene-1 as a shell. A polyolefin alloy is prepared by adopting two sections of polymerization by the following steps: carrying out polymerization reaction of polybutylene-1 or polypropylene in the first section; on the premise that the activity of a catalyst is not fully diminished, conveying the polymer to equipment in the second section to be reacted with an introduced monomer butene-1 or propylene; and freely adjusting the temperature, pressure and time conditions of reactions in two sections to obtain a novel polybutylene alloy material with a controllable relative amount. The preparation methods disclosed by the invention can be used for producing the polybutylene alloy material which comprises 10-99% by mass of isotactic polybutene-1, 1-80% by mass of isotactic polypropylene and 0.01-10% by mass of a butene-1-propylene copolymer. The yield can be greatly improved and the equipment utilization ratio is improved.
