Abstract

The utility model relates to a magnetic transmission high sealing wind pump which is composed of an inner magnetic bag connected with wind pump shafts, a sealing sleeve barrel which is sheathed outside the inner magnetic bag and is hermetically connected with the wind pump body, and an outer magnetic sleeve arranged outside the sleeve barrel. 6 to 14 even magnetic sheets are inlaid on the inner magnetic bag and the outer magnetic sleeve. The polarities of the adjacent magnetic sheets, which face outwards, are opposite. The reasonable allocation of the magnetic sheets can better transfer torque and ensure the wind pump to be sealed in a complete and non-leakage mode. The wind pump is capable of satisfying the requirements of high sealing working condition, and is used for transmitting high purity gases.

Description

Magnetic transmission high sealing wind pump
The utility model relates to the shaft sealer of air pump.
Impeller in the present normally used air pump, its motor and the pump housing all adopts axle to connect or belt transmission, and a position that makes spool is exposed in the extraneous space.Therefore, although the air pump body seals, the position of axle can not reach high-seal, can't resolve the complete sealing problem of air pump, is difficult to adapt to the needs of high envelope sex work condition.The for example inflation of fluorescent tube inert gas causes the impure of inflation in the fluorescent tube owing to the between centers of air pump leaks, thereby influences the luminosity and the working life of fluorescent tube.The pump that has is become one in order to reach sealing purpose with the motor and the pump housing, and motor and axle, impeller all are sealed, and this one pump is cumbersome when maintenance is particularly changed motor, and dismounting is all inconvenient.
The purpose of this utility model is to provide a kind of magnetic transmission high leak tightness air pump, and this air pump passes through the high magnetic fields transmitting torque, thereby the air pump axial region is sealed fully, makes air pump can adapt to the requirement of high leak tightness operating conditions.This air pump maintenance easy accessibility need not be opened seal casinghousing and motor can be taken off.
Disk pack in the utility model is achieved in that and installs on the air pump axle, should interior disk pack be in the groove of sleeve-like disk pack surface, to embed 6-14 piece magnetic sheet to constitute, the diameter of interior disk pack is a φ 45-75 millimeter, magnetic sheet should be even number and arrange along disk pack body circumference uniform distribution, the length of magnetic sheet is the 30-80 millimeter, thickness is the 4-8 millimeter, and its outside one side is as the N utmost point or the S utmost point, and its polarity to the outside of adjacent magnetic sheet is opposite; Interior disk pack is installed the seal sleeve of thin-walled outward, leaves certain interval between this sleeve and interior disk pack, and to guarantee the normal operation of disk pack, the sleeve and the pump housing are tightly connected; Outside seal sleeve, be provided with outer magnetic sleeve, this outer magnetic sleeve is slightly larger than the magnetosheath body of seal sleeve by an end internal diameter and the magnetic sheet of embedding magnetosheath body inwall constitutes, the quantity of magnetic sheet, arrangement mode should be identical with interior disk pack, the other end and the motor shaft of outer magnetic sleeve link, and the internal diameter of the embedding magnetic sheet end of outer magnetic sleeve is 100 millimeters of φ 70-φ.
This magnetic transmission high leak tightness air pump in use, the running of driven by motor outer magnetic sleeve, but because the moving magnetic field transmitting torque, the interior disk pack in the seal sleeve is driven run-in synchronism, interior disk pack drives the running of air pump axle and impeller again, plays the effect of suction, inflation, air-supply.The utility model adopts the high power capacity magnetic material to make magnetic patch, by the reasonable disposition of magnetic patch, improves the ability of rotating magnetic field transmitting torque.Be suitable for 1.1KW following (containing 1.KM), air quantity is at 200M 3/ n, the pressure various air pump below 17000Pa does not need to add in addition starting arrangement, can guarantee proper functioning.The sealed sleeve of the axial region of this air pump seals fully, and whole air pump forms the state that is hedged off from the outer world, and does not have the between centers leakage problem, can guarantee to be transferred the purity of gas, has adapted to the needs of high sealing operating conditions.This pump is applicable to the conveying of various inert gases, noble gas.Motor of this air pump and air pump axle do not have the mechanical coupling relation, and place outside the seal sleeve, and the dismounting maintenance is very convenient.
Be described further below in conjunction with accompanying drawing
Fig. 1 is the structural representation of this magnetic transmission high leak tightness air pump
Fig. 2 is the magnetic sheet configuration schematic diagram of interior disk pack
The utility model as shown in Figure 1, disk pack 6 on negative pump shaft 8, installing, embed magnetic sheet 5 on the circumference of interior disk pack, seal sleeve 4 is placed in outside the interior disk pack, and is tightly connected with air pump body 7, and the two keeps certain clearance, one end of outer magnetic sleeve 2 is placed in outside the seal sleeve, its inwall embeds polylith magnetic sheet 3, and the other end of outer magnetic sleeve is and the axle sleeve of motor shaft 1 coupling, lock onto on the motor shaft with key.Fig. 2 has showed the outward appearance of interior disk pack, and along the uniform configuration of its cylindrical 6-14 piece magnetic sheet, it is the S utmost point or the N utmost point to the outside, the extremely alternate configuration of its S utmost point and N, promptly S utmost point both sides is the N utmost point, the both sides of the N utmost point is the S utmost point, to meet the characteristic rule in magnetic field, bring into play the effect of rotating magnetic field transmitting torque effectively.The number of magnetic sheet, length thickness all be the performance index by air pump, determined with prolonged and repeated test as calculated.Prototype test proves, need not to add in addition starting arrangement and can directly drive air pump running and proper functioning.
