Abstract
The utility model relates to a testing device for the distribution of the spray density, which is used for the quick and large-scale measurement of the micro pressure under the condition of spray. The utility model consists of a collecting pipe, a valve guide, a feed valve, a drain valve, a micro pressure sensor and a computer. Since only one micro pressure sensor is used in the testing device, the pressure and the quantity of the water in a plurality of collecting pipes which are densely distributed are quickly measured, so as to greatly reduce the device investment and the system error, improve the automation degree of the system, and reduce the manpower. The utility model is used in the spray density testing for the single fluid spraying nozzle taking the water as the medium, or the two-fluid spraying nozzle taking the water and the air as the medium.
Description
The utility model relates to a kind of spray flux density distribution tests device, specifically a kind of the utilization carried out fast under water smoke, the aerosol condition that a large amount of minute-pressure power is measured and is converted to the mechanism for testing of spray flux density by computing machine, is applicable to the spray flux density test of single fluid or two-fluid spray nozzle.
Nozzle is very extensive in sector applications such as metallurgy, chemical industry, environmental protection, cleanings, the good and bad product quality and the qualification rate of directly influencing of its spray characteristics, and it is the crucial characteristic of nozzle that spray flux density distributes, and has represented the homogeneity of atomize.Inappropriate spraying cooling can cause properties of product not conform to, and brings very big economic loss.As casting blank of continuous casting machine cooling in the STEELMAKING PRODUCTION with nozzle performance not the good general cause the strand inhomogeneous cooling, produce defectives such as surface crack, underbead crack.The spray nozzle density distribution situation is tested, improve its properties percent of pass, very big economic benefit and social benefit are arranged improving the quality of products.
The spray flux density proving installation of present existing proving installation such as domestic certain university, the employing graduated cylinder is measured the water yield in the collection bottle one by one, manually carries out data processing.Its weak point need to be manpower many, and measuring period is long, and the manual measurement link is many, and error is big; And for example the electric atomizing density measurement device of Jiangsu factory has all adopted a micropressure sensor at each density measure point.Its weak point is that plant investment is up to surplus 100 ten thousand yuan, and can't carry out setting unified zero point (initial point) verification to proving installation, add the difference of each micro-pressure sensor test error, make the data of surveying error is inconsistent separately, reduced measuring accuracy.
The purpose of this utility model is to provide a kind of can overcome above deficiency, and invest low, simple in structure, easy to operate, the automaticity height, a people just can finish the device of test.
The utility model in order to achieve the above object, designed a kind of spray flux density distribution tests device, by collector pipe (1), conduit (2), a micro-pressure sensor (3), computing machine (4) is formed, it is characterized in that valve is led (5) in addition, a water intaking valve (6), a draining valve (7), solenoid valve (8), micro-pressure sensor and solenoid valve are installed in valve and lead, each collector pipe all links to each other with a solenoid valve, collector pipe was led with valve and is communicated with when solenoid valve was opened, water pressure in each collector pipe acts on the micropressure sensor successively, computing machine is connected with sensor, and sensor is converted to the water yield with pressure signal and demonstrates test result on computers.
The utility model proving installation has following advantage: (1), easy to operate, test data is accurate.Spraying is catchmented and is adopted the collector pipe be connected with graduated cylinder before the utility model, manually reads the water yield in each graduated cylinder, manual record, error is big, length consuming time, the data of surveying once more by artificial input computing machine, waste time and energy.Adopt the utility model proving installation, sensor is converted to pressure signal and directly is sent to computing machine after the water yield and carries out data conversion treatment automatically, demonstrates test result, the automaticity height, a people just can finish test, swift and convenient to operate, visual result, accurate.(2), investment is low.With present conventional device under each collector pipe all sensor installation compare, greatly reduced investment, overcome the relative error of different sensors measurement data.(3), easy to maintenance.Only need the precision of a liquid level sensor is carried out periodic check, just can guarantee the measuring accuracy of total system.
Further specify the utility model spray flux density distribution tests device with accompanying drawing below.
Fig. 1 is the utility model proving installation structural representation.
(1) is that collector pipe, (2) are that computing machine, (5) are for valve is led, (6) are that water inlet pipe, (11) for collector pipe in cooling fluid liquid level, (12) for nozzle spray stream pattern, (13) for nozzle, (14) be collector pipe upper guard-plate for solenoid valve, (9) for drainpipe, (10) for draining valve, (8) for water intaking valve, (7) for conduit, (3) for micropressure sensor, (4) among the figure.
The utility model spray flux density distribution tests device is described in further detail in conjunction with the embodiments: embodiment 1: adopt the jet density of the utility model test water cooling jet to distribute, the requirement test parameter is: cooling water pressure is 0.3MPa, and the jet length of nozzle and collector pipe is 300mm.Test process: nozzle is installed earlier, is adjusted itself and collector pipe group center centering, and lifting nozzle clamping device, the adjustment jet length reaches 300mm; Closure set water pipe upper guard-plate; Configure measurement parameter in computing machine, carry out initialization operation, computer system is carried out following operation automatically: open the solenoid valve of all collector pipes earlier, drive water valve again into, reach certain water level to collector pipe; Close water intaking valve, and open draining valve, all liquid levels are reduced to the liquid level of setting to the collector pipe, and the solenoid valve of water intaking valve and all collector pipes all cuts out automatically; Open water yield control electric control valve button on computers, computing machine is adjusted water spray pressure automatically, and to the water pressure setting value, baffle plate is opened automatically, and collector pipe begins to catchment; Catchment to the time of setting, pneumatic baffle is closed automatically, hydraulic pressure in each collector pipe acts on the micropressure sensor successively, the pressure signal that micropressure sensor automatically will be measured in the collector pipe one by one is converted into the water yield, the water yield that micropressure sensor is measured is changed the spray flux density data that demonstrate test on computers automatically, and draws the spray flux density distribution curve.Therefore, whole device is after nozzle installs, and test process only needs a people just can finish in that computer operation is indoor, easy to operate, test data quick, stable, accurately.
The utility model spray flux density distribution tests device is specially adapted to Yi Shui, water and air and is the test of spray flux density distribution character of all kinds of nozzles of main heat eliminating medium.
