Description
The utility model relates to a kind of basic electrical component, and specifically a kind of joint has electromagnet.
We know that electromagnet is to utilize the iron-core coil of energising to attract armature or keep certain machine components, workpiece in a kind of electrical equipment of fixed position, can be widely used in various brakes, electromagnetically operated valve and various electromagnetic relay and the contactor.In general, electromagnet is made up of coil, iron core and armature three parts.With regard to core configuration, at present, mainly contain two kinds of solenoid electromagnet and coiled electrical magnets, solenoid electromagnet produces attraction with the end face of iron core column in the coil, and coiled electrical magnet can produce attraction by the whole iron core face that comprises iron core cylinder and outside ring surface, like this when identical current excitation, air gap was less when solenoid electromagnet started adhesive, the suction-combining force is bigger, and after the adhesive, safeguards that the suction-combining force is less; Air gap was bigger when coiled electrical magnet started adhesive, and the suction-combining force is less, and after the adhesive, its adhesive area is big, safeguards that the suction-combining force is bigger, and from energy-conservation angle, the two respectively has superiority, but all undesirable.At present, energy-saving electromagnet is arranged also, as patent 92216400.2, it is improved from coil and control circuit, reaching purpose of energy saving, and its complex structure, replacement is convenient inadequately.Patent 96227796.7 has proposed a kind of energy-saving electromagnet, and the magnetic conduction convex edge has been set up in its periphery at static iron core, and armature is included in the static iron core, air gap reduces, the suction-combining force increases, and produces great momentum during down to adhesive, has reduced the useful life of electromagnet and has produced bigger noise.
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of structure reasonable, and control mode is the same with traditional electromagnet, and it is easy to use to replace, stable work in work, durable energy-saving electromagnet.
For achieving the above object, a kind of energy-saving electromagnet, it is provided with static iron core, coil, armature, and static iron core is provided with the magnetic conduction convex edge, and armature is included in the static iron core, its underpart connects a push rod admittedly, it is characterized in that armature top is provided with an end cap and static iron core magnetic conduction convex edge is connected and fixed, be provided with a cavity between the top of armature and the end cap, be provided with a cavity between bottom and the static iron core, be provided with sealing ring around the armature, be provided with sealing ring between push rod and static iron core.
Also be provided with several exhaust holes on the utility model armature, be provided with the adjusting plug in the exhaust hole.
The utility model is respectively established a cavity owing to armature is upper and lower, at armature adhesive or dispose procedure, air pressure in two cavitys increases respectively or reduces, its active force increases with the operation of armature, and direction is opposite with the traffic direction of armature, thereby played cushioning effect, reduced the sound, prolonged the useful life of electromagnet.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model structural representation.
As can be seen from Figure 1, a kind of energy-saving electromagnet, it is provided with static iron core 1, coil 2, armature 3, coil 2 is on the iron core column of static iron core 1, can connect relevant control circuit, be used to the starting current that provides suitable and keep electric current, the setting of coil, the structure of control circuit, connection belong to prior art, and this does not describe in detail.On the utility model static iron core, the periphery of the adhesive face of itself and armature is provided with magnetic conduction convex edge 4, magnetic conduction convex edge and iron core integrative-structure, and its whole armature adhesive bread is with which.Can reduce starting current and keep electric current, reach purpose of energy saving.The armature bottom connects a push rod 5 admittedly, and push rod 5 passes from static iron core, is used for contacting with controlled brake, starts or closes various brakes.
An end cap 6 is established on the utility model armature top, and the magnetic conduction convex edge 4 of end cap 6 edges and static iron core is connected and fixed, and like this, just forms a cavity between armature top and the end cap, also forms a cavity between bottom and the static iron core.In order to make above-mentioned two cavitys keep sealing, be provided with sealing ring 7 around the armature 3, be provided with sealing ring 8 between push rod 5 and the static iron core 1.When electromagnet energising adhesive, the volume of lower cavity is compressed, pressure increases, and the upper cavity volume increases, and pressure reduces, like this, the second half at electromagnetic actuation has tangible cushioning effect, and is same, at the electromagnet dispose procedure, also play cushioning effect, thereby controlled brake such as crane etc. are operated steadily.Therefore, reduce the sound of work of electromagnet widely, prolonged the useful life of electromagnet.The utility model armature 3 is provided with several exhaust holes 9, and air can move at two cavitys, is provided with in the exhaust hole to regulate plug 10, and to regulate air flow amount, preventing that pressure differential from crossing ambassador's armature can not be by complete adhesive.After the adhesive, make two cavity pressures identical by exhaust hole.
The utility model is provided with two cavitys on patent 96227796.7 bases, the motion of armature has had certain buffering, has reduced operating noise, has prolonged the useful life of electromagnet.The utility model is rational in infrastructure, and control mode is the same with traditional electrical magnet, and reliable working performance, stable is a kind of desirable energy-saving electromagnet.
