The working principle of the utility model are as follows:
Subject filter is fitted into test device first, subject pipeline switching valve is switched into reflux branch, and cut off
Water flow adjusting valve opens oil stream adjustable valve, makes to test the test(ing) medium in fuel tank and continues through circulation progress purified treatment,
Water content test is carried out to background, if not up to required, needs to continue purification water removal, is wanted if reaching water content
It asks, subject pipeline switching valve is switched into subject filter, and make test(ing) medium full of subject filter, row with lesser flow
Air in net subject filter, then subject pipeline switching valve is switched into reflux branch, test pump is opened, water flow is then turned on
Regulating valve and water injecting pump adjust water injecting pump and bypass pump according to test parameters, and adjust the pressure difference of water dispensing device and requiring
In range, then carry out whether upstream sampling valve sampling and testing water concentration meets the requirements, when water concentration reaches it is to be aspired for stability after, will be by
Examination pipeline switching valve switches to subject filter side, when starting tester, and corresponding sampling and testing is carried out, until providing
The condition of time or test requirements document terminates test after reaching.
The characteristics of the utility model, is:
1, since shutdown and other operations can have some impact on system, and then the fluctuation of water concentration is influenced, especially set
Subject pipeline switching valve has been counted, subject filter is mounted directly after background water concentration is up to standard, is not required to after adjusting water concentration is up to standard
Installation is shut down by test specimen, directly switching subject pipeline switching valve just can be carried out test.
2, oil sump tank system can bring a certain amount of test(ing) medium to flow out due to replacing and sampling, at the same can win tool and
The contacts such as table top cause particle contamination and air to contact, and are situated between if this part test medium directly returns test fuel tank and will cause to test
The fluctuation of matter background water, and by oil sump tank auxiliary pump through oil sump tank polishing filter, oil sump tank except after water filter, test is situated between
Matter is substantially up to standard, reaches and not only meets test requirements document, but also the purpose of save the cost.
If 3, subject filter separation water effect is bad, the background water content of test(ing) medium will have a direct impact on, in turn
Upstream water concentration is influenced, test result is finally influenced, therefore increases service tank to avoid these factors, concrete operating principle
As follows: the test(ing) medium of test loop returns to service tank, carries out circulating purification always under the action of auxiliary purifies replenishment pump
Water removal, when as low as certain limit, fluid level controller can issue signal for test dielectric fluid position in test fuel tank, circulation supply at this time is cut
Valve work is changed, Vavle switching to feeding side, defeated test(ing) medium is sent to test using removing water filter together and ensure
Fuel tank, when liquid level reaches setting position, fluid level controller issues signal, circulation supply Vavle switching to recycling side；Work as auxiliary
When oil tank liquid level reaches the upper limit, fluid level controller issues signal, and the valve of circulation supply at this time, which is opened, actively gives test fuel tank supply examination
Medium is tested, when reaching service tank liquid level lower limit, circulation supply switching valve switches back into circulation side, two fluid level controller phases
Mutually auxiliary operation.
4, when the test flow very little of pilot system, water injection rate will be smaller, and the minor fluctuations of system pressure will shadow
The stabilization of Xiangshui County's concentration, but when under bigger test flow, then without such situation, therefore increases bypass pump and increase side
Road flowmeter carries out the injection of water according to stable larger flow when carrying out smaller flow test, mixing stable examination
It tests medium to squeeze by bypass pump except water filter is shunted, and enters service tank after being measured by by-pass meter
Circulation, test flow at this time is exactly that main system flow subtracts bypass flow, and flow at this time can be from any one greater than 0
Number starts.
The basic principle of the utility model, main feature and advantage has been shown and described above, it is practical new not departing from this
Under the premise of type spirit and scope, there are also various changes and modifications, these changes and improvements both fall within requirement and protect the utility model
The scope of the utility model of shield.
