超声波清洗槽的设计
发布者:admin  日期:2013-10-24  点击:3252
清洗机网是以生产、销售、维护超声波清洗机为一体的公司,近年来公司不断发展技术力量,创新生产技术手段,生产的产品销往全国各地,受到客户的一致好评,今天让大家了解一下超声波清洗槽的设计。
超声波清洗槽由内槽和外壳组成,内槽的外表面(一般在槽底外表)粘接超声波换能器,槽内盛清洗液。槽一般用耐腐蚀的不锈钢板制成,过于厚会影响超声波的辐射,槽的内壁,尤其是粘有换能器的辐射板要平整抛光,不能有伤痕,否则易产生空化腐蚀,缩短使用寿命。为避免被清洗工件直接与槽壁板接触而划伤,一般用镂空吊篮(清洗篮)或支架将清洗件悬吊在清洗液中。网篮的骨架应尽可能地小而轻,一般用不锈钢丝编成或用其它反射声良好的材料做成。结构上要使超声波受阻小而清洗液易于流动。内槽的尺寸要根据清洗件的大小和形状而定。清洗件的总表面积大应大于内槽的体积。粘有换能器的辐射板(如槽底板)所承受的电功率强度一般低于1.5W?CM2)(用电压换能器时,大多数应在0.5-1w/cm2之间)。过高的强度会加速辐射板表面的空化腐蚀,同时由于过剧烈的空化所产生的气泡会影响能量传递,使远离辐射面得液体空间声强变弱而达不到均匀清洗的目的。在普通的清洗槽中,由于液面的反射,在清洗槽中会产生驻波,使得在液体空间有些区域声压最小(波节处),有些地方声压最大(波腹处)而造成清洗干净程度不均匀。为减少驻波的形成,有时清洗槽的形状要特别设计,或采取其他措施,例如扫频工作方式。清洗件在槽中的排列要有一定的间隔,而最窄小的面应朝向换能器的辐射面,以免妨碍声辐射到整个清洗槽空间。 更多超声波清洗槽信息请登录清洗机网:www.qingxijiw.com

Cleaning machine is the production, sales, maintenance of ultrasonic cleaning machine for the whole company, the development of the company technical force is constantly in recent years, technology innovation and production, products are sold throughout the country, by the customer the consistent high praise, let everyone know about ultrasonic cleaning tank design.
Ultrasonic cleaning groove by groove and an outer shell, the outer surface of the inner groove (general appearance at the bottom of the groove) bonding ultrasonic transducer, groove Sheng cleaning fluid. Groove is generally made of stainless steel plate corrosion, too thick will affect the ultrasonic radiation, cell wall, especially the radiation plate adhered with transducer to smooth polished, can not have scar, or it is easy to produce cavitation corrosion, shorten the service life. To avoid direct contact with the workpiece cleaning tank wall plate and scratch, hollow basket with general (cleaning basket) or stent will clean the suspension in the cleaning solution. The basket frame should be small and light, generally with the stainless steel wire plaited or made of other reflected sound good material. The structure to make the ultrasonic cleaning liquid flows easily blocked small. The inner tank size according to the size and shape of the cleaning element set. The total surface area of cleaning of large should be greater than the groove volume. Stick with a radiation plate transducer (such as the tank bottom plate) power strength under generally lower than 1.5W? CM2) (voltage transducer, most should be between 0.5-1w/cm2). High strength will accelerate cavitation corrosion radiation plate surface, at the same time due to severe cavitation bubbles generated will affect the energy transfer, so far away from the radiation surface liquid space sound intensity becomes weak and uneven cleaning purpose. In the cleaning tank in general, because the level of reflection, in the cleaning tank will produce a standing wave, the liquid space some regional pressure minimum (nodes), some local pressure maximum (antinode) caused by uneven clean degree. In order to reduce the formation of standing wave cleaning trough, sometimes the shape to be specially designed, or take other measures, such as sweep mode. Cleaning items in the groove are arranged to have a certain interval, and the narrow surface radiation toward the transducer, so as not to impede the sound radiation into the cleaning groove space.
