Description
Technical field
The utility model relates to a kind of blowing motor apparatus, especially relates to a kind of blowing motor apparatus that has Teflon diaphragm seal and bowl-type rubber pad sheet.
Background technology
Reflow soldering (Reflow Oven) is the equipment that is used for the circuit board that is loaded with electronic devices and components is carried out soldering.It is through providing a kind of heating environment, thereby solder(ing) paste being heated melt lets surface-pasted components and parts and circuit board combine reliably through the solder(ing) paste alloy.The solder(ing) paste that soldering is used is that the scaling powder and the powder scolder of smectic are processed paste; Be coated in the soldering position of each components and parts of circuit board through printing; And accurate above that mounted with electronic components, utilize reflow soldering to carry out heat fused, reach reliable soldering to components and parts.Reflow soldering comprises air furnace and nitrogen furnace, and nitrogen furnace is when soldering, to guarantee the certain nitrogen content of surrounding environment (generally at refluxing stage), and when playing a kind of welding, the effect of gas shield improves the quality and the stability of welding effectively.
In the nitrogen reflux stove, motor can produce negative pressure in rotary course, and the air of outside can be come in, and then influences the concentration of nitrogen.Traditional blowing motor all is directly to adopt motor mount plate, on motor mount plate, punches then, logical N
2Carry out supply, offset the influence that external air causes, but can cause the increase of use cost like this.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of N that saved to be provided
2Use amount, omitted the N on the motor mount plate simultaneously
2Make-up system has been practiced thrift the blowing motor apparatus that has Teflon diaphragm seal and bowl-type rubber pad sheet of cost greatly.
The purpose of the utility model can realize through following technical scheme: a kind of blowing motor apparatus that has Teflon diaphragm seal and bowl-type rubber pad sheet; It is characterized in that; This blowing motor apparatus comprises blowing motor, diaphragm seal fixed head, goes up diaphragm seal, motor mount plate, lower sealing piece, warming plate, warming plate backplate, pad, impeller; Described motor mount plate top connects successively goes up diaphragm seal, diaphragm seal fixed head and blowing motor; The motor mount plate below connects lower sealing piece, warming plate, warming plate backplate and pad successively, and the diaphragm seal fixed head is passed in the rotating shaft of described blowing motor successively, upward diaphragm seal, motor mount plate, lower sealing piece, warming plate, warming plate backplate, pad are connected with impeller.
Described motor mount plate is provided with the hole that is complementary with rotating shaft, and the described diameter of bore of going up diaphragm seal is than the little 0.30mm～0.50mm of motor shaft diameter, and the diameter of bore of described lower sealing piece is than the little 0.30mm～0.50mm of motor shaft diameter.
Described upward diaphragm seal is the Teflon diaphragm seal.
Described lower sealing piece is the Teflon diaphragm seal.
Described pad is the bowl-type rubber pad sheet.
Compared with prior art, the utlity model has following advantage:
1, the utility model is located at motor mount plate two Teflon diaphragm seals up and down simultaneously and has prevented N
2Between the gap of motor shaft and motor mount plate, flow out, so just saved about 10% N
2Also omitted simultaneously the N on the motor mount plate
2Make-up system has been practiced thrift cost greatly;
2, the utility model also has the bowl-type rubber pad sheet, and the bowl-type rubber pad sheet is fitted with the machine module shell after assembling, has blocked the air-flow (N of machine intimate
2) moving to other local string, so also saved N
2, practiced thrift cost.
