真空上料机是根据物料的输送量，匹配相应规格的气源压力、仓泵和管道尺寸，可自动将各种物料输送到包装机、注塑机、破碎机的料斗中，传统人工上料的不足，也了给料过程中粉料溢出的问题，如果在生产中遇到吸力不足的情况，可以通过以下方式加以。

A vacuum feeder is a machine that matches the corresponding specifications of gas source pressure, bin pump, and pipeline size based on the conveying volume of materials. It can automatically transport various materials to the hoppers of packaging machines, injection molding machines, and crushers, solving the shortcomings of traditional manual feeding and the problem of powder overflow during the feeding process. If there is insufficient suction in production, the following methods can be used to solve the problem.

一、管道检查

1、 Pipeline inspection

造成真空上料机吸力小的管路难题，可能是由于电焊焊接难题导致的管道毁坏，或者是料管被块状物料阻塞，难题关键产生在真空上料机的入料口出及其管路的相接处，因此可以通过管道的检查来排除这一故障。

The problem of low suction in the vacuum feeding machine may be caused by pipeline damage due to welding difficulties or blockage of the material pipe by block materials. The key problem lies in the inlet and outlet of the vacuum feeding machine and the connection of the pipeline. Therefore, this fault can be eliminated through pipeline inspection.

二、过滤装置检查

2、 Filter device inspection

检查真空上料机过滤芯是不否被阻塞，过滤芯归属于易耗品，在应用的全过程中，直径会伴随着使用年限慢慢被阻塞，过滤芯如若发生堵塞，应拆装超声清洗三十分钟或立即拆换，以保证真空上料机的正常运转。

Check if the filter element of the vacuum feeder is blocked. The filter element belongs to consumables, and its diameter will gradually be blocked along with its service life during the entire application process. If the filter element is blocked, it should be disassembled and cleaned with ultrasonic for thirty minutes or replaced immediately to ensure the normal operation of the vacuum feeder.

三、闸阀密封性检查

3、 Gate valve sealing inspection

在长时间的应用中，应按时检查真空上料机各闸阀的密封性是否符合规定，检查闸阀的密封环是否磨坏。闸阀的密封性问题，会导致真空上料机的真空值损害，导致吸力不足的问题，而且在各种严苛的自然环境下更应重视按时维修。

In long-term applications, the sealing performance of each gate valve of the vacuum feeder should be checked on time to ensure compliance with regulations, and the sealing ring of the gate valve should be checked for wear and tear. The sealing problem of gate valves can cause damage to the vacuum value of the vacuum feeder, resulting in insufficient suction, and timely maintenance should be emphasized in various harsh natural environments.
