The invention relates to the field of a motor, and specifically relates to a high-rotation speed and rapid heat-conduction motor. The motor comprises a stator, a rotor sleeved in the stator and a rotation shaft penetrating the rotor. The motor also comprises a shell and a base which fit with each other. The shell sleevesthe stator. Vent holes are arranged on a shell end face. A positioning and installing hole post is arranged at the center of the base. A circuit board is arranged on an outer side frame of the base. A drainage fan is fixedly arranged on the rotation shaft and is located at the outer side of the shell end face. A plastic package body is packaged out of the stator. A plastic package reinforcing connection ring is integrally connected with the end face of one side of the plastic package body facing towards the base. The plastic package reinforcing connection ring is arranged against the side wall face of the shell. Airflow at the rear end of the circuit board is sent in the motor through the circuit board and the vent holes on a base plate. Equally, the airflow between the circuit board and the base plate is sent in the motor through the vent holes on the base plate, then the heat in the motor is absorbed by the airflow, and then the airflow is rapidly exported out of the motor through vent holes on an incline reinforced hole slot wall. The whole motor has the advantages of high integrity, compact structure, convenient disassembly, low cost, high strength, high stability and low noise.

The invention relates to the field of motors, and particularly to a quick heat radiation motor. The motor comprises a stator, a rotor which is sleeved in the stator, a rotating shaft which penetrates through the rotor, a housing which sleeves the stator and is provided with ventilating holes on a housing end surface, and a base which is provided with a positioning mounting hole column at the center, wherein the housing and the base are adapted with each other. The outside rack of the base is provided with a circuit board. A drainage fan is fixedly arranged on the rotating shaft at outside of the housing end surface. A plastic sealed member is sealed outside the stator. The end surface, which faces the base, of the plastic sealed member is integrally connected with a plastic sealed reinforcing connecting ring which is arranged in a manner of abutting against the sidewall surface of the housing. Air flow at the back end of the circuit board is sent into the motoring through the circuit board and the ventilating holes on a base board. Similarly, the air flow between the circuit board and the base board is sent into the motor through the ventilating holes on the base board. Heat in the motor is absorbed, and then the heat is quickly leaded out of the motor through ventilating holes of inclined reinforcing hole slot walls. The quick heat radiation motor has advantages of high integrity, compact structure, convenient detachment, low cost, high strength, high stability and low noise.

The invention relates to the field of motors, and in particular relates to a stable motor. The stable motor comprises a stator, a rotor sleeved in the stator and a rotating shaft arranged on the rotor in a penetrating manner, and also comprises a shell and a base which are fit with each other, wherein the shell is sleeved on the stator and provided with vent holes in the shell end face, the base is provided with a locating mounting hole column at the center, a circuit board is erected on the outer side of the base, a draught fan is fixedly arranged on rotating shaft on the outer side of the shell end face, the stator is packaged with a plastic package body, and a circle of plastic package reinforced connecting ring arranged close to the side wall of the shell is integrally connected on the end face of the plastic package body facing the base side. Air flows at the rear end of the circuit board are sent into the motor via vent holes in the circuit board and base plate, in the same way, the air flows between the circuit board and base plate are sent into the motor via the vent holes in the base plate, then absorb heat in the motor, and then are rapidly exported from the motor via vent holes in the inclined reinforced pored groove wall. The whole motor is strong in integrality, compact in structure, convenient to dismount, low in cost, high in strength, good in stability and low in noise.

The invention provides a power supply system in which while enlargement of a space for placement of the power supply system is suppressed, strength of a housing is improved. The power supply system (1) includes a plurality of batteries (10), a cooling portion (20) through which a refrigerant for cooling the plurality of the batteries flows, a housing (30) that has a bottom plate (31), a top plate (32), and side walls (33, 34) that extend upright from a peripheral edge of the bottom plate to a peripheral edge of the top plate, the housing accommodating the plurality of the batteries and the cooling portion, and a compressor configured to pump the refrigerant to the cooling portion. In the housing, a strength member that extends in a direction in which the side walls face each other and reinforces the housing is mounted on the bottom plate or the top plate. The compressor is disposed in a position in which the compressor and the strength member are overlapped in the upright direction of the side walls.

The invention provides a coating for lost foam casting. The coating is prepared from the following raw materials by weight percent: 40%-47% of water glass with the modulus of 2.0-2.5, 52-59% of bauxite with the granularity of 62-74 microns or silica sand with the granularity of 62-74 microns, not more than 0.2% of emulsifier op-10, and 0.95% of phenolic resin liquid. The application method of the coating for lost foam casting comprises the following steps of: firstly, mixing the water glass, the emulsifier op-10 and the phenolic resin liquid together, and then adding the bauxite or the silica sand, and stirring all the materials evenly; then painting a lost foam module with the mixture pass by pass while drying; drying after the last pass of painting, and then cooling to room temperature; roasting the lost foam module; preserving heat at a temperature not lower than 400 DEG C; after burying the lost foam module in a box, carrying out slight vibration and then performing casting molding. The coating for lost foam casting can be used for solving the problems of recarburization, pore formation and slag inclusion in the lost foam casting process; the application time from coating painting to completion of roasting is reduced to not more than 32 hours from previously at least 48 hours; besides, the coating is excellent in high temperature resistance, high in shell mould strength and excellent in moulded shell collapsibility; the cost can be reduced by **-**.

The invention discloses a method for preparing a CaZrO3 shell used for precision casting of titanium and titanium alloys. Calcium zirconate is used as a filler, and binders such as zirconium acetate or yttrium sol that do not react with titanium alloys are pretreated and formed. , hardening, sintering and other processes to make the shell. The mold shell has a small reaction degree with titanium and titanium alloys, and the thickness of the dirt layer formed on the surface of the casting is small; the strength of the calcium zirconate ceramic shell is high, and the surface finish of the casting is high; the coating containing calcium zirconate is stable, not easy to gel, and suspended Good performance, long storage time.
