Abstract
The utility model relates to a sealing system for a reciprocating motion rod piece. The sealing system comprises the motion rod piece, permanent magnet rings, magnetic powder, non-magnetic materials and soft magnetic materials. The magnetic powder is located in the clearances between the motion rod piece and permanent magnet ring sets, the permanent magnet ring sets are separated by the non-magnetic materials, and the soft magnetic materials are arranged at the lowest ends of the permanent magnet ring sets. According to the sealing system for the reciprocating motion rod piece, subsection multi-stage sealing is adopted, the pressure withstanding value is high, the structure is simple, maintenance is convenience, the influence of the running speed of the rod piece is low, and almost no leakage exists.
Description
Technical field
The utility model belongs to mechanical sealing equipment technical field, is specifically related to a kind of sealing system of reciprocatory motion rod member.
Background technique
At present, the external filling seal ring of motion rod member, conventional filler are teflon, fiber screen.But must there is certain gap between the two, be difficult to prevent high and low leakage of calming the anger.
Therefore,, in order to adopt above-mentioned technology for detection, necessaryly provide a kind of novel Intelligent infrared carrying out flaw detection system.
Model utility content
For addressing the above problem, the purpose of this utility model is to provide segmentation multi-stage sealed, and pressure resistance is higher, simple in structure, easy to maintenance, affected by rod member motion speed low, almost the sealing system of leak free reciprocatory motion rod member.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of sealing system of reciprocatory motion rod member, and it comprises motion rod member, magnet ring group, magnetic, nonmagnetic substance, soft magnetic material; Wherein magnetic is arranged in the gap of motion rod member and magnet ring group, between described magnet ring group, is nonmagnetic substance interval, and described soft magnetic material is placed in permanent magnetism
Iron hoop group bottom.
The sealing system of reciprocatory motion rod member of the present utility model is further set to: described magnet ring group is enclosed within the outside of motion rod member, and rod member is that nonmagnetic substance, material are fiber.
Compared with prior art, the utlity model has following beneficial effect:
1. good airproof performance.Adjacent permanent magnet polarity position opposite forms circulation magnetic circuit, improves the magnetic flux between permanent magnet and motion rod member; Secondly, the quality of magnetic is little, and the rod member that is difficult for passive movement is taken out of and occurred stratification.
2. cost is low.System mainly adopts permanent magnet and magnetic to form, cheap.
Brief description of the drawings
Fig. 1 is the structural representation of the sealing system of reciprocatory motion rod member of the present utility model.
1:1-motion rod member in figure, 2-magnet ring, 3-nonmagnetic substance, 4-magnetic, 5-soft magnetic material.
Embodiment
Refer to shown in Figure of description 1, the utility model is a kind of sealing system of reciprocatory motion rod member, and it comprises motion rod member (1), magnet ring (2), nonmagnetic substance (3), magnetic (4), soft magnetic material (5); Wherein magnetic (4) is arranged in the gap of motion rod member (1) and magnet ring (2), is nonmagnetic substance (3) interval between described magnet ring (2), and described soft magnetic material (5) is placed in magnet ring (2) bottom.
The working principle of the sealing system of reciprocatory motion rod member of the present utility model is: described magnet ring (2) has formed circulation magnetic field with soft magnetic material (5), magnet ring (2) is enclosed within motion rod member (1) outside, between the space of magnet ring (2) and motion rod member (1), insert magnetic (4), motion rod member (1) is in reciprocal running, magnetic (4) under the effect in circulation magnetic field in gap is not stratified, final rod member (1) sealed magnetic performance in the time of high-speed motion does not decline, thereby reaches the effect of sealing.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any amendment of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
Claims (2)
1. a sealing system for reciprocatory motion rod member, is characterized in that: comprise motion rod member (1), magnet ring (2), nonmagnetic substance (3), magnetic (4), soft magnetic material (5); Wherein magnetic (4) is arranged in the gap of motion rod member (1) and magnet ring (2), is nonmagnetic substance (3) interval between described magnet ring (2), and described soft magnetic material (5) is placed in magnet ring (2) bottom.
2. the sealing system of reciprocatory motion rod member as claimed in claim 1, is characterized in that: described magnet ring group is enclosed within the outside of motion rod member, and rod member is that nonmagnetic substance, material are fiber.
