在盲孔零件批量清洗作业中,由于其结构特点,大量零件被放置在清洗笼中,同时浸入清洗液中。由于清洗液的表面张力,凹槽、狭缝和盲孔中的空气不能及时排除,而是被堵在盲孔中,使清洗剂不能充分接触零件表面,很难有效地彻底盲孔中的残余切削液、压力油和冷却液。那么这个时候,超声波清洗设备如何进行盲孔的清洗呢?
In the batch cleaning of blind hole parts, due to its structural characteristics, a large number of parts are placed in the cleaning cage and immersed in the cleaning solution at the same time. Because of the surface tension of the cleaning fluid, the air in the grooves, slits and blind holes can not be removed in time, but is blocked in the blind hole, so that the cleaning agent can not fully contact the surface of parts, it is difficult to effectively and thoroughly remove the residual cutting fluid, pressure oil and coolant in the blind hole. So at this time, how to clean the blind hole ultrasonic cleaning equipment?
种方法:
在设计五金件超声波清洗机时,可以在罐体上加一个压缩空气喷嘴。外部工厂气源,在清洗盲孔零件时,将工件慢慢放入,尽可能让水流入孔内。零件放置后,利用压缩空气使水产生大量水柱冲击工件。为了使堵塞在孔口中的气泡爆裂,达到更好的对盲孔部位的超声波清洗效果。
The first method:
In designing ultrasonic cleaning machine for hardware, a compressed air nozzle can be added to the tank body. External factory air source, when cleaning the blind hole parts, slowly put the workpiece into the hole, as much as possible to let the water flow into the hole. After the parts are placed, compressed air is used to generate a large number of water columns to impact the workpiece. In order to make the bubbles blocked in the orifice burst, to achieve a better ultrasonic cleaning effect on the blind hole.
第二种方法:
The second method:
使用中高频结合的
超声波清洗设备。利用高频超声波,原理是高频振荡,使堵塞在盲孔中的气体超声波清洗机的气泡破裂,铁屑被一扫而空。
The use of high frequency combined with ultrasonic cleaning machine. The use of high frequency ultrasonic, the principle is high frequency oscillation, so that blocked in the blind hole in the gas ultrasonic cleaning machine bubble burst, iron filings were swept away.
一般情况下,超声波清洗设备使用时的频率在很大程度上决定了超声波清洗机的清洗效果。超声波空化阈值与超声波清洗机的频率密切相关。频率越高,气蚀阀越高。也就是说:频率越低越容易产生空化,而在频率低的情况下,液体被压缩变薄的时间间隔更长,这样气泡在解体前就可以长到更大的尺寸.因此,我们可以通过增加空化强度来提高清洗效率。
In general, the frequency of ultrasonic cleaning equipment to a large extent determines the cleaning effect of ultrasonic cleaning machine. Ultrasonic cavitation threshold is closely related to the frequency of ultrasonic cleaning machine. The higher the frequency, the higher the cavitation valve. That is: cavitation is more likely to occur at lower frequencies, and at lower frequencies, the liquid is compressed and thinned at longer intervals, allowing bubbles to grow to larger sizes before they disintegrate. Therefore, we can increase the cleaning efficiency by increasing the cavitation intensity.
盲孔太小,水压无法使堵在盲孔中的气泡爆裂。超声波的传播是以水为介质,即超声波清洗机说只要水能到达的地方,超声波就会存在,从而实现清洗。但少量未渗入清洗剂的盲孔无法清洗干净。
The blind hole is too small for water pressure to burst the bubbles trapped in it. The transmission of ultrasonic is water as the medium, that is, ultrasonic cleaning machine said that as long as the water can reach the place, ultrasonic will exist, so as to achieve cleaning. However, a small number of blind holes that have not infiltrated into the cleaning agent cannot be cleaned.
