Abstract
The invention discloses a kind of accumulator oil end permeation detection devices, include across the channel that accumulator pedestal is connected to accumulator oil end, the S type transparent pipelines that one end is connected to channel, the other end of S type transparent pipelines is oiling end, and S types transparent pipeline is less than the height of the bending part far from oiling end close to the height of the bending part at oiling end；The present invention runs business into particular one micro-adjustment to the pedestal of accumulator, can be detected to the permeation at accumulator oil end only with a transparent pipeline, simple in structure, it is easy to operate, and the present invention is provided with scale at the oiling end of transparent pipeline, can not only detect whether permeation, can also be detected to permeation amount.
Description
Technical field
The invention belongs to accumulator detection technique fields, especially a kind of accumulator oil end permeation detection device.
Background technology
Certain model hydraulic servomechanism uses piston accumulator as a kind of supplementary energy in mechanism, for reducing fluid
Pulsation and hydraulic shock is absorbed, this accumulator cylinder uses high-strength alloy steel making, to improve the hardness of cylinder inner wall and resistance to
Mill property, is handled using hard chrome plating.
Hard chrome plating is that it is higher, wear-resisting that hardness is obtained from Cr-plating Bath under conditions of strict temperature control, current density
The electroplating technology of the good chrome layer of property, and when hard chrome plating layers of chrome reaches certain thickness, it is easy to make to crack inside layers of chrome, due to
Cylinder inner wall surface roughness, local defect and surface residual stress influence trend and the distribution of crackle, and individual chromium can be caused to plate
Layer forms penetrability channel, and accumulator high pressure nitrogen micro-crack penetrability channel from cylinder inner wall Hard Chromium Coating slowly penetrates oil
Liquid causes fluid and nitrogen mixing, volume in servo mechanism fuel tank to increase, causes pasta voltage overproof.And accumulator list before this
Part do not have to detect when delivering accumulator oil end whether the method for permeation, cause accumulator single-piece to deliver qualified, and mounted in complete machine it
Find that pasta is overproof afterwards.
Invention content
The purpose of the present invention is to provide one kind can detect the cities accumulator You Duan whether permeation, improve complete machine deliver it is qualified
The accumulator oil end permeation detection device of rate.
Realize that the technical solution of the object of the invention is：
A kind of accumulator oil end permeation detection device, include across the channel that accumulator pedestal is connected to accumulator oil end,
The other end of the S type transparent pipelines that one end is connected to channel, S type transparent pipelines is oiling end, and S types transparent pipeline is close to oiling end
Bending part height be less than far from oiling end bending part height.
Compared with prior art, the present invention its remarkable advantage：
(1) present invention runs business into particular one micro-adjustment to the pedestal of accumulator, can be to accumulator oil end only with a transparent pipeline
Permeation be detected, it is simple in structure, it is easy to operate.
(2) present invention is provided with scale at the oiling end of transparent pipeline, can not only detect whether permeation, can also be to oozing
Tolerance is detected.
Present invention is further described in detail below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structural schematic diagram of accumulator oil of the present invention end permeation detection device.
Specific implementation mode
In conjunction with Fig. 1：
A kind of accumulator oil of the invention end permeation detection device, including accumulator pedestal 7 is passed through to be connected to accumulator oil end
Channel, the S type transparent pipelines that one end is connected to channel, the other ends of S type transparent pipelines is oiling end 2, and S type transparent pipelines lean on
The height of the bending part at nearly oiling end 2 is less than the height of the bending part far from oiling end 2.
The oiling end 2 of S type transparent pipelines indicates scale 3.
S type transparent pipelines are that transparent hose 5 is bent.
The type transparent pipeline one end S is connected to by pagoda head with the channel in accumulator pedestal.
In conjunction with Fig. 1：
Embodiment：
A kind of accumulator oil end permeation detection device, include across the channel that accumulator pedestal 7 is connected to accumulator oil end,
One end is by the S type transparent pipelines that are connected to the channel in accumulator pedestal 7 with pagoda head 6, the other end of S type transparent pipelines
Oiling end 2, oiling end 2 indicate scale 3.
Embodiment 2：
A kind of accumulator oil end permeation detection device, include across the channel that accumulator pedestal 7 is connected to accumulator oil end,
By the transparent hose 5 being connected to the channel in accumulator pedestal 7 with pagoda head 6, the other end of transparent hose 5 is oiling for one end
End 2, oiling end 2 indicates scale 3.
Accumulator is during single-piece seals, and by accumulator traverse, upward, operator is by pagoda for the passway of accumulator pedestal
First 6 and transparent hose 5 be screwed at passway, and entire transparent hose 5 is made to form S types, and close to the bending part height at oiling end 2
Less than the bending part height far from oiling end, hydraulic oil 4 is injected in transparent hose 5 later, it is transparent soft to wait for that hydraulic oil 4 is filled into
Near the scale 3 of pipe 5, stops filling, and clamp transparent hose 5 using clip, prevent fluid from overflowing, it is quiet later to put accumulation of energy
Device, daily in observation transparent hose 5 the case where bubble 1；If oily end has the infiltration of bubble 1, bubble 1 that can float to accumulator pedestal
Peak, and float to the bending part of transparent hose 5 along transparent hose 5, can will be transparent soft with the continuous aggregation of bubble 1
Hydraulic oil 4 in pipe 5 ejects, there is the variation that a scale 2 is used for observing 4 end of hydraulic oil in the end of transparent hose 5, is sentenced with this
The volume of bubble 1 is penetrated at oil-break end.
Claims (1)
1. a kind of accumulator oil end permeation detection device, it is characterised in that：Including passing through accumulator pedestal to connect with accumulator oil end
