Description
Technical field
The present invention relates to electric connector pulling-out force test device and its method, belongs to hydraulic control test system technology neck
Domain.
Background technology
Underwater connector is indispensable electronic component in the Underwater Engineering such as ocean and weapon system-of-systems, and it develops
Can trace back in the 1950s, and developed rapidly after World War II promote business and military engineering field reclaimed water under
The continuous application of electrical equipment.At present, as marine petroleum development and the continuous of weapon combat system develop to blue water,
The more aobvious ample scope for abilities of underwater connector.By taking marine petroleum development as an example, in 2013-2017, the input of deep water oil development accounts for
The ratio that exploitation of offshore oil and gas is always put into will be more than 50%, and sight is turned to exploitation with detecting degree also by each major oil companies one after another
Very low deep-sea field, promoted underwater connector increasingly receive much concern and the research boom of academia.
Under water in field of connectors, there is a kind of electric connector with specific function underwater isolating electric coupler one by one,
It can safely and reliably work in environment under water, realize that the underwater of electrical connector plug socket is automatically separated, and to electrical connection
Device, which patches face and the signal contact at bonding wire end, has power-off protection effect, even if the signal contact that electric connector patches face meets seawater
Short circuit, the signal contact at its bonding wire end also will not short circuit.Underwater isolating electric coupler is widely used in national marine and defends each force
Type system, deep-sea overocean communications and investigation, submarine, MISSILE LAUNCHING, torpedo, ocean be commercial and military engineering water under electrically
In device, such as modern guided missile, Guided Torpedo needs leading various navigation datas, target of attack parameter real-time loading before transmission
On bullet, torpedo, realization is connected and disconnected from function with submarine equipment, and loading passage among these is that underwater separation electrically connects
Device, they are the essential components of the underwater combat system such as submarine, torpedo.
Existing underwater sealing electric connector can only carry out plug operation in atmosphere, be placed into after connecting in water, when
When underwater installation needs repaired, changed, increased and decreased, it is necessary to which separation and the company of device can be just electrically connected by equipment is emerged
Connect, this mode of operation wastes time and energy, cost is high.Different areas of activity under water, the cable that such as comes off, diving apparatus, Underwater Camera,
On the equipment such as electric equipment, water under high pressure valve, pressure transmitter, underwater telephone, rapid rush-repair equipment on offshore oilfield, electrically
Interface is often desirable to be plugged under water, to realize the quick, assembling that economically carries out equipment under water, increase and decrease, more
Work, this market such as changing has urgent demand to underwater pluggable sealed electrical connector, and the usage amount of underwater electrical connector is very
Greatly, and influence that the reliability of connector is transported to underwater power network, underwater communication, underwater installation and Underwater resources is huge.Therefore
The development of underwater electrical connector test equipment is also imperative.
China's marine settings manufacturing industry is started in the seventies and eighties in last century, and due to related disciplines such as material science
Weakness, high pressure resistant material, buoyant material etc. turn into the limitation in ocean petroleum developing field, can only support deep-sea by outsourcing foreign material
The research of technology.Cable plug interconnection technique is in starting stage, only Some Enterprises unit and Research Center under domestic water at present
Primary Study, and the temporarily experience accumulation without this respect are carried out, corresponding supporting test device is even more not know where to begin.State at present
Mainly there are FMC, Oil States, Cameron etc. in development preferable, well-known company in this field of connector under water on border,
But its test equipment is submarine pipeline connecting test device, there is no for testing electric connector transient state pulling-out force test device,
And it is unable to test connector and disengages moment pulling-out force.
The extensive use of underwater cartridge make it that the test of underwater cartridge is more and more important.Normally due to Cost Problems, under water
The method that the testing experiment of element uses land simulation, i.e., tested in a seal-off pressure cavity volume.It is and existing underwater
Connector test equipment has the disadvantages that：
1. state's female connector pulling-out force test device is not related to hydraulic pressure environment, underwater electrical connector test is not suitable for；
2. domestic tensile test is mostly the test of static load pulling force, only a small number of test devices are related to drawing with certain speed
It is de-, but test speed scope is smaller, but pulling speed has considerable influence to pulling-out force, under water weapon etc. pull speed compared with
Big occasion can not meet test request；
3. domestic pulling-out force test device can measure the connector pulling-out force within 2500N, it is impossible to meet pulling-out force compared with
Big actual condition；
4. Foreign Underwater connector testing device can not test the transient state pulling-out force of underwater connector, transient state pulling-out force index
On the one hand the reliability of electric connector connection is may determine that, on the other hand when needing actively to pull electric connector, to calculating electricity
The pulling force that connector is applied has directive significance；
5. speed is adjusted to adjust manually, automaticity is relatively low.
The content of the invention

Water pressure control system establishes 0~6MPa range hydraulic pressure in pressure measuring cylinder (38)；
Moisturizing accumulator (39) ensure electric connector pull during variation in water pressure in pressure measuring cylinder (38) within 5%；
With oil contamination plugged filter warning function and oil pressure, hydraulic pressure overpressure alarm function；
Oil cylinder rodless cavity pressure, rod chamber pressure, energy storage pressure, pressure measuring cylinder hydraulic pressure, oil cylinder piston displacement, speed are in display
It has been shown that, and there is data storage function.
7. the test method of electric connector pulling-out force test device according to claim 5, it is characterised in that：
Described TT＆C system carries out differential to oil cylinder piston rate signal, obtains the acceleration of piston movement, according to piston plus
Speed a, cylinder movement part and drawstring gross mass m, frictional force F under friction speed is measuredf, electric connector delays in air
Pulling-out force F ', cylinder rod chamber pressure p during slow disengagement1, rod chamber active area A1, rodless cavity pressure p2, rodless cavity acting surface
Product A2, hydraulic pressure p3, rod areas A3Can be according to F=F '+p2A2+p3A3-p1A1-Ff- ma is calculated when electric connector pulls
Power F1, in the case where electric connector has disengaged, repeat oil cylinder and stretch out, pressurize, withdraw, buffering course, ensure speed, hydraulic pressure
It is consistent when power pulls with electric connector, obtain power F2, F1With F2The peak value of difference is pulling-out force.
