the nozzle 62 is internally provided with a spray hole 621, and the diameter of the spray hole 621 gradually decreases from inside to outside, so that water flows through the nozzle 62 and is sprayed out in a radiation manner.
It should be noted that the number of the nozzles 62 is several and is uniformly distributed on the nozzle base 6 at a certain interval.
Specifically, the diameter range of the nozzle 62 is 1.1-1.3 mm.
It should be noted that, in performing the hydrodynamics calculation on the system, the following assumptions are made:
1. seawater is an ideal fluid;
2. the density of the seawater is constant (rho is 1.03g cm-3);
3. the flow is constant and swirl-free;
4. the mass force is an attractive force, and a force-potential function exists;
5. integration along the flow line;
6. the water pump operates at rated pressure and flow.
The main design parameters of the continuous water jet in engineering application comprise dynamic parameters such as hydrostatic pressure (fluid pressure for short), jet flow, flow speed, power, recoil force and the like of generated jet;
for continuous jet, the operation depth of the net washing machine is set to be 0.1m, the length of the high-pressure rubber pipe is set to be 10m, the aperture is 20mm, and the following relational expression (1) can be obtained by applying Bernoulli equation between the water outlet of the water pump and 2 sections of the nozzle inlet:
Z1+p1/ρg+α1v12/2g＝z2+p2/ρg+α2v22/2g+hw
in the formula: z1 is a static water head at a water outlet of the water pump, Z2 is a static water head of a nozzle of the screen washer, P1 is pressure at the inlet of a water outlet pipe of the water pump (taking a working pump with pressure P1 of 14MPa and flow q of 120 L.min < -1 > as an initial design parameter), P2 is pressure of the nozzle of the screen washer, V1 is high-pressure water speed at the water outlet of the water pump, V2 is high-pressure water speed at the nozzle of the screen washer, alpha 1 and alpha 2 are kinetic energy correction coefficients, the values of the kinetic energy correction coefficients depend on the flow velocity distribution situation on a water cross section, the flow velocity distribution is uniform, the alpha 1 and the alpha 2 are close to 1, the values are larger than 1 when the flow velocity distribution is nonuniform, alpha is approximately equal to 1.05-1.10 in a gradient flow, where alpha 1 is equal to 1.05, hw is flow resistance loss of a pipeline, and hw is equal to lambda Lv12/dp2g (considering local loss lambda is equal to 0.3);
from the continuous equation of 2 sections, equation (2) can be derived: q-1/4 v1 pi d 12-n/4 v2d22
The jet pressure formula (3) can be obtained by combining the vertical type (1) and the vertical type (2):
p＝p2＝p1+ρg(z1-z2)+7.62ρq2/π2(13.0806Mpa)
using bernoulli's equation (ignoring height differences) between the nozzle inlet and nozzle outlet equation (4):
(P3/ρg)+(v32/2g)＝(p4/ρg)+(v42/2g)
wherein p3 is the high pressure water nozzle inlet pressure; p4 is high pressure water nozzle outlet pressure; v3 is the high pressure water nozzle inlet velocity; v4 is the high pressure water nozzle exit velocity;
due to the continuous equation (5) between 2 sections: q ═ n/4 ═ v3 π d32 ═ n/4 ═ v4 π d42
Therefore, formula (6): v4 ═ 0.5 [2(p3-p4)/(ρ 1 (1-d 44/d34)) ]
Since p3> > p4, d44/d34< <1, then equation (6) can be simplified to equation (7):
V4＝(2p3/ρ)0.5
by substituting formula (7) for formula (5), formula (8) can be obtained:
d＝(4q/πn(2p3/ρ)0.5)0.5
when p3 ═ p2 ═ p;
taking into account the flow coefficient and the nozzle efficiency coefficient, a nozzle diameter formula (9) is obtained:
d＝d3＝d2＝0.7η(q/(μnp0.5))0.5
wherein q is jet flow (L.min-1);
p is jet pressure (MPa);
n is the number of the spray holes, and n is 5 (5 spray holes are selected to be uniformly distributed on a front baffle of the screen washer at an interval L (100.00mm) in the circumferential direction);
mu is a nozzle flow coefficient (0.9-0.92);
eta is the nozzle efficiency coefficient (1.05-1.3);
velocity of jet
For the seawater jet (ρ ═ 1.03g · cm-3), v ═ 44.11p0.5 from formula (7);
where v is the known jet velocity of the jet flow (m · s-1) in the axial direction of the jet, and the emergent flow can be calculated from q ═ vA, i.e. the jet flow is equal to the jet outlet velocity multiplied by the nozzle outlet cross-sectional area, i.e.:
formula (11): q is 2.07nd2p, wherein q is jet flow rate (L.min-1); d is the nozzle exit diameter (mm);
jet power: the velocity and flow rate of the nozzle determined here are both theoretical values, while the actual velocity and flow rate are both smaller than the theoretical values, and after the jet flow rate and pressure are determined, the jet power can be calculated from the following relational expression;
formula (12): p is the jet power (W) in 16.67 pq. Equation (12) shows that jet power is a function of pressure and flow;
substituting formula (11) into formula (12) yields formula (13):
P＝34.6nd2*p3/2
from equation (13), it can be seen that the jet power at the nozzle outlet is a function of the pressure at which the jet is generated and the size and number of nozzles. Equation (13) also shows that jet power is proportional to the square of the nozzle diameter, the 3/2 th power of the pressure, i.e., jet power is much more sensitive to changes in nozzle diameter than to changes in pressure. The nozzle diameter is increased by 1 time, the jet power is increased by 3 times, and the pressure is increased by 1 time, the jet power is increased by 1.8 times. Therefore, the jet power can be effectively improved by increasing the diameter of the nozzle;
comprehensively obtaining: the nozzle diameter was 1.128mm, the injection angular velocity was 0.04rad S-1, and the injection pressure was 13.0806 MPa.
