Technical field
The present invention relates to a kind of proving installation of accessory peculiar to vessel, refer in particular to a kind of discharge test unit of air pipe head.
Background technology
Air pipe head, is mainly used in main cabin gas exchange action, by air-breathing and breathe be air pressure in the cabinet of cabin close to atmospheric pressure, within making its pressure remain on the design pressure of cabin cabinet, can prevent seawater in addition, rainwater enters cabin cabinet.At present, also do not have a kind of reliable, the discharge of effective method to air pipe head to test, the quality of product is affected, and the application follow-up to product is made troubles.
Summary of the invention
In order to overcome shortcoming and the weak point of background technology, the invention provides a kind of reliable, effectively and the discharge test unit of the high air pipe head of test accuracy.
Technical scheme of the present invention is: a kind of discharge test unit of air pipe head, comprise centrifugal water pump, low flush tank, elevated tank, testing conduit, control valve, flowmeter, frequency meter, pressure transducer and DC digital voltmeter, by centrifugal water pump, the water in low flush tank is delivered to elevated tank, described testing conduit is positioned at the below of elevated tank, described elevated tank is communicated with one end of testing conduit by sewer pipe, the other end of described testing conduit is for installing exemplar, described control valve, turbo flow meter is installed on described measuring channel successively, described frequency meter is connected with flowmeter, described pressure transducer is located on the testing conduit between flowmeter and exemplar, described DC digital voltmeter is connected with pressure transducer.
Described sewer pipe is connected with testing conduit by stabilizing feed well.
Described flow counts turbo flow meter.
Run-down pipe is connected with between described elevated tank and low flush tank.
the present invention has following beneficial effect:this test unit adopts unique, special project organization, can the flow of reasonable, reliable and effective test sample, ensures the quality of product, improves its application performance.
Accompanying drawing explanation

Embodiment
Be described further for embodiments of the invention below:
As shown in the figure, a kind of discharge test unit of air pipe head, comprise centrifugal water pump 1, low flush tank 2, elevated tank 3, testing conduit 4, control valve 5, flowmeter 6, frequency meter 7, pressure transducer 8 and DC digital voltmeter 9, by centrifugal water pump 1, the water in low flush tank 2 is delivered to elevated tank 3, described testing conduit 4 is positioned at the below of elevated tank 3, described elevated tank 3 is communicated by sewer pipe 10 one end with testing conduit 4, the other end of described testing conduit 4 is for installing exemplar 11, described control valve 5, flowmeter 6 is installed on described measuring channel 4 successively, described frequency meter 7 is connected with flowmeter 6, described flowmeter 6 is turbo flow meter, described pressure transducer 8 is located on the testing conduit 4 between flowmeter 6 and exemplar 11, described DC digital voltmeter 9 is connected with pressure transducer 8.During test, air pipe head is placed on the end of testing conduit 4, start centrifugal water pump 1, water in low flush tank 2 is pumped in elevated tank, unnecessary water is back in low flush tank by run-down pipe, water in elevated tank flows through stabilizing feed well 12 through sewer pipe 10, testing conduit 4 is flow to after current stabilization by stabilizing feed well 12, manual turn control valve 5, start the discharge regulated in measuring channel, and show by sending frequency meter 7 to after flowmeter 6 test, water velocity is faster, frequency is larger, stop when the float of air pipe head is sucted by current regulating, and draw maximum frequency by frequency meter 7, then down ten Frequency points are selected successively, stop regulating after being adjusted to required Frequency point by control valve 5, and convert voltage to by the pressure that pressure transducer detects and be presented at DC digital voltmeter, and record atmospheric pressure by barometer, numerical value is drawn by formulae discovery, each Frequency point calculates numerical value by which, finally calculate mean value, each Frequency point respectively does 2 tests.In addition, the pipeline that testing conduit can adopt multiple bore different, corresponding from the air pipe head of different bore respectively, to realize the object measured simultaneously, improve testing efficiency.This test unit adopts unique, special project organization, can the flow of reasonable, reliable and effective test sample, ensures the quality of product, improves its application performance.
In the present invention, described sewer pipe 10 is connected with testing conduit 4 by stabilizing feed well 12.By the steady flow result of stabilizing feed well, make flow more stable, improve test accuracy.
In the present invention, run-down pipe 13 is connected with between described elevated tank 3 and low flush tank 2.Adopt run-down pipe 13 to make unnecessary water be back in low flush tank, effectively can keep the pressure stability of elevated tank.
Embodiment should not be considered as the restriction to invention, but any improvement done based on spirit of the present invention, all should within protection scope of the present invention.
