Description
Technical field
The present invention relates to the measuring method of relevant fluidics sprinkler parameter, especially a kind of method of measuring the each attached wall signal discharge of fluidics sprinkler.
Background technology
Fluidics sprinkler is the novel water-saving irrigation equipment of a kind of new construction and new principle of work, comprises in the course of the work two states of direct projection and attached wall.The direct projection state that is initially of fluidics sprinkler makes this side form low pressure when shower nozzle one side-draw obtains signal discharge enough, and the shower nozzle both sides have just formed pressure reduction, thereby makes current present the rotation that attached wall state promotes shower nozzle.
For fluidics sprinkler, the number of signal discharge has determined whether shower nozzle can complete rotary work smoothly, and directly affects the important hydraulic performances such as its step frequency, range and water distribution.Current research mainly relies on the water intaking position of Experience Design signal nozzle, whether shower nozzle is completed to rotary work is observed, important water-power performance parameter is measured, thereby can't accurately know signal water yield when the attached wall of fluidics sprinkler completes rotary work, also can't accurately know the impact of the signal water yield on important hydraulic performance simultaneously.If in particular cases cause fluidics sprinkler can not complete rotary work or important hydraulic performance is poor at some, just can not analyze it whether due to the former of the signal water yield thereby cause, thereby can't effectively solve this problem in science.
As mentioned above, in design process, due to the signal discharge of not knowing the each attached wall of fluidics sprinkler, fluidics sprinkler rotary work or important hydraulic performance occur completing when poor, and the means that just can not understand the signal water yield by science effectively solve.Therefore, the present invention proposes a kind of method of measuring the each attached wall signal discharge of fluidics sprinkler to address the above problem, tool has very important significance.
Through retrieval, also there is no at present the relevant patent of declaring.
Summary of the invention
The technical problem to be solved in the present invention is that science is understood the impact of fluidics sprinkler signal discharge on shower nozzle rotary work and important hydraulic performance.Based on above-mentioned purpose, the invention provides a kind of method of measuring the each attached wall signal discharge of fluidics sprinkler, comprise the following steps:
(a) before on-test, utilize conduit by the signal nozzle of fluidics sprinkler and enter water nozzle to link together, the water intaking position of conditioning signal mouth makes it get signal water; Set the working pressure of shower nozzle, make fluidics sprinkler remain on the state of steady operation, when fluidics sprinkler can not remain on the state of steady operation, need to readjust the water intaking position of signal nozzle, until fluidics sprinkler remains on stable duty.The steady-working state of described fluidics sprinkler is that shower nozzle spin stabilization, attached wall are stable, the uniform state of rotational speed.Consider the situation that signal current that when work has just started, signal nozzle is got may be stable not, need to set under working pressure steady operation at shower nozzle and start again to measure the acquisition test data after more than 10 minutes.
(b) start to measure test figure; Read the total attached wall frequency n in the fluidics sprinkler course of work, record reads total attached wall frequency n time spent t of institute simultaneously.Repeat above-mentioned surveying work m time, measure respectively and complete total attached wall frequency n institute's time spent at every turn
t i (i=1,2 ... m), obtain according to measurement result the averaging time that total attached wall frequency n is spent
thereby, obtain each attached wall institute's time spent
.The total attached wall frequency n of the described fluidics sprinkler read is for being more than or equal to 1 time.Described duplicate measurements work m time is for being more than or equal to 1 time.
(c) keep being connected of conduit and signal nozzle, disconnect conduit and enter being connected of water nozzle, make fluidics sprinkler remain on the state of direct projection extraction signal water, according to t ＇ averaging time obtained, measure the interior signal water yield q that can receive of corresponding time t ＇.
(d) will receive signal discharge q first divided by the total attached wall frequency n of the fluidics sprinkler in step (b), then by result again divided by each attached wall institute's time spent in step (b)
t, the q ＇=q/ (nT) obtained is the signal discharge of the each attached wall of fluidics sprinkler.
The accompanying drawing explanation
Fig. 1 is the flow chart of steps that shows the each attached wall signal water yield method of measurement fluidics sprinkler of the embodiment of the present invention.
Embodiment
The invention provides a kind of method of measuring the each attached wall signal water yield of fluidics sprinkler.For above and other objects of the present invention, feature and advantage can be become apparent, cited below particularlyly go out preferred embodiment, and coordinate appended graphicly, be described below in detail.
As shown in Figure 1, at first, chosen the external fluidics sprinkler of a kind of signal water as experimental prototype, before on-test, utilize conduit by the signal nozzle of fluidics sprinkler and enter water nozzle and link together, the water intaking position of conditioning signal mouth makes it get signal water, sets the working pressure 250kPa of shower nozzle, makes fluidics sprinkler remain on the state of steady operation.At the shower nozzle steady operation start to measure test figure after 20 minutes.
Then, read total attached wall number of times in the fluidics sprinkler course of work 100 times, and record it and take time, repeat above-mentioned surveying work 3 times, measuring institute's time spent is respectively 56.73s, 60.26s, 58.65s, obtaining according to measurement result the averaging time that total attached wall spends for 100 times is 58.55s, obtains each attached wall time spent 0.5855s of institute.
Then, the maintenance conduit is connected with signal nozzle, disconnects conduit and enters being connected of water nozzle, makes fluidics sprinkler remain on the state that signal water is extracted in direct projection, measures in corresponding time 58.55s and can receive signal water yield 165ML
Then, will receive signal water yield 165ML first except the total attached wall of fluidics sprinkler that above reads 100 times, and then, except upper each attached wall time spent 0.5855s of institute, obtained 2.82ML/s, be the signal water yield of the each attached wall of fluidics sprinkler.
