Abstract
The utility model discloses a wind cooling system for round tube type straight electrical machinery. A shell of a round tube type straight electrical machinery is provided with an inlet and an outlet ventilation slots, and an inner primary iron core is also opened with an inlet and an outlet air channels. The heating problem in the condition of frequent starting work can be solved effectively and the wind cooling system for round tube type straight electrical machinery can be ensured to work normally via using a ventilator for ventilating through the side direction of a dispersion box and directly cooling the primary iron core, a primary coil and a secondary surface.
Description
The utility model is a kind of cylindrical linear ventilation cooling system, and it belongs to the ventilation or the cooling system of motor, and it is air-cooled to adopt ventilation blower to carry out, and the air channel of ventilation is arranged in the static iron core of magnetic circuit.
Linear electric motors are owing to special relative motion mode between primary and secondary, and its radiating condition is better than general electric rotating machine usually.But short stroke, higher cylindrical linear (induction) motor of load factor, because in fact it be in the Fraquent start state, heating is serious, as not taking effective cooling measure, just can't operate as normal.The general ventilation blower that adopts carries out air blast cooling to the cylindrical linear surface, but can't solve inner heat dissipation problem well.
The utility model is to avoid above-mentioned the deficiencies in the prior art, and purpose provides a kind of improved ventilation cooling system.Adopt ventilation blower that wind regime is provided, air intake from the side, directly cool off the inside that requires cold wind can enter cylindrical linear, so that solve the serious heating problem under the cylindrical linear Fraquent start condition of work better, guarantee that cylindrical linear can operate as normal under this condition of work.
Task of the present utility model is finished as follows: offer two of axial ventilation slots on the relative position of cylindrical linear casing, an air intake, another air-out; Also offer the air channel on elementary iron core, the cold wind that ventilation blower blows into from the side just can directly cool off elementary iron core and primary coil, and secondary surfaces also obtains cooling in addition.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the local longitudinal sectional drawing of the utility model concrete structure.
Fig. 2 is the cutaway view of the utility model Fig. 1 along the A-A line.
Fig. 3 is the side view that offers ventilation slot on the casing of the utility model cylindrical linear.
Fig. 4 is the punching figure of the elementary iron core of the utility model cylindrical linear.
With reference to Fig. 1, Fig. 2 and Fig. 3. Offer vertically two ventilation slots (11) on the relative position of the casing (8) of cylinder type linear electric motors, an air intake, another air-out. The cooling-air of ventilation blower (7) is behind a dispersion case (6), enter from the side the air inlet duct (9) of the elementary iron core (5) of cylinder type linear electric motors inside through ventilation slot (11), arrive again the air gap between elementary (3), secondary (1), through the exhaust passage (10) and the upper relative ventilation slot (11) of another casing (8) of elementary iron core (5), inner heat is taken out of cylinder type linear electric motors again. Thereby solve serious heating problem, guarantee the normal operation under the condition that frequently starts to work.
Fig. 4 is the punching figure of the elementary iron core of the utility model cylinder type linear electric motors.
The wide t that is made as of upper two the relative ventilation slots of cylinder type linear electric motors casings (8) (11)1, the wide of two relative air inlet ducts (9) of elementary iron core (5) and exhaust passage (10) is t2, t then1≥t
2 The thickness that change punching such as elementary iron core (5) is t3, desirable t then2＝t
3。
The utility model is compared with prior art, its advantage is that casing (8) and the internal structure to cylindrical linear changed little, the outside is also only set up one and is disperseed case, just can solve the serious heating problem of the cylindrical linear under the Fraquent start condition of work.Be power source with the cylindrical linear, many occasions of Fraquent start all can be used, and for example: high-frequency electromagnetic hammer, piling machine and riveting machine etc. can enlarge the range of application of cylindrical linear.
Embodiment of the present utility model is: the cylindrical linear Mean Input Power is 3KW, play dynamicthrust 150kg, air gap is 1mm between primary and secondary (3) and (1), be used for the high-frequency electromagnetic hammer, striking frequency is 300 times/minute, stuffy cooling cisco unity malfunction adopts the warm instrumentation amount secondary surfaces temperature of point up to 200 ℃.Improved by above-mentioned each content of the utility model, adopt 500W ventilation blower (7), cylindrical linear casing (8) is gone up the wide t of ventilation slot (11)
1=10mm, the air inlet duct (9) of elementary iron core (5) and the wide t in exhaust passage (10)
2=7mm, elementary iron core (5) is the thickness t of punching repeatedly
3=7mm, under above same high-frequency electromagnetic hammer condition of work, can operate as normal after the cooling of ventilating, adopting the warm instrumentation amount secondary surfaces temperature of point once more is 100 ℃.
