The buffer tube is provided with air which is a necessary condition for the normal operation of the homogenizer, when the homogenizer is in operation, the air density is smaller, the upper part of the buffer tube is the air lower part of the buffer tube is the feed liquid, when the feed flow rate is higher than the flow rate requirement of the homogenizer, the feed liquid in the pipeline is stored in the buffer tube by compressing the air in the buffer tube, so that the feed flow rate is constant, the vibration of the feeding and discharging tube of the homogenizer can be reduced as much as possible, if the buffer tube cannot be discharged in time, once the space above the buffer tube for accommodating the air is completely filled with the feed liquid, the buffer effect of the buffer tube can be reduced, and thus the feeding and discharging tube of the homogenizer is triggered to vibrate or cavitation is generated.
