Northmanni Open Hydrau ratio reversing solenoid valvae SV-VIII

In components qui facile ad generare strepitu hydrau cogitationes plerumque considerari ut pumps et valvulae et valvulae maxime redundantiam valvulae et electro directional valvulae. Multa factores agere sonum. Duo genera strepitus inundare valvae Velocitatem sonus mechanica sonus. Vox in velocitate sonus est maxime per oleum vibrationis, cavitationem et hydraulicarum impulsum. Mechanica sonitus maxime causatur per impulsum frictio partium valvae.

(I) strepitu fecit per inaequaliter pressura

Et gubernator valvae partem gubernator relevium valvae est facile-ut-vibrate parte ut ostensum est in Figura III. Cum inundans sub altum pressura, axial ostium gubernator valvae est valde parvum, solum 0.003 ~ 0.006 cm. Et fluxus regio est valde parvum et fluxus velocitas est valde altum, quod potest pervenire 200m / s, quod facile causat inaequatio pressura distribution, vibration vi radialis pyramidis valvae et vibration. Insuper et ellipticity causatur per machining de pyramidis valvae et pyramidis valvae sedem, in lutum haeret gubernator valvae portum et deformatio de pressura regulare fons et faciam cum vibratione de pyramidis valvae. Ideo plerumque considerandum quod gubernator valvae sit vibratio fontem sonitus.

Because of the existence of elastic element (spring) and moving mass (cone valve), it constitutes a condition for oscillation, and the front cavity of the pilot valve acts as a resonant cavity, so the vibration of the cone valve is easy to cause the resonance of the whole valve and make noise, which is usually accompanied by severe pressure jump.
