Vacuum metering is a kind of equipment widely used in mining, metallurgy, coal, building materials, chemical industry, electric power, grain and other industries. It is used to continuously or quantitatively transport bulk, granular and powdery materials from silos or other storage devices to receiving devices. Simply put, it is a kind of conveying equipment. There are many kinds of feeding equipment, such as impeller vacuum measurement, vibration hopper, electromagnetic vibration vacuum measurement and motor vibration vacuum measurement.


It has the characteristics of small size, low noise, light weight, high working frequency, low power consumption, stepless feed regulation, easy installation and maintenance, etc. It can be used in the automatic control of production process and realize the automation of production process. In general production process, feeding equipment will not be submerged by faults, but once the faults can not be solved in time, it will cause huge economic losses.


Vacuum metering


Vacuum metering feeding is a very common problem, which is caused by a variety of reasons. In order to solve this problem, we need to carefully check and troubleshoot one by one in order to solve the problem quickly and effectively. For a long time, it has been a headache for manufacturers to use feeding equipment when feeders can not be fed. Today, we summarized the causes and solutions of this problem in Dongyuan, hoping to give you some help. Usually there are several reasons for not feeding: first, the gap between the core and armature of the feeder is too large or too small, if this situation is summed up, it can not reach the normal amplitude, affecting the vacuum measurement. In addition, it may be due to excessive feeding, which leads to the accumulation of materials in the frame, the increase of lifting resistance, the stress of screw conveyor, and the unsmooth operation of hopper, resulting in fewer feeds and keeping the average feeding.


It may also be due to the inconsistency between the parts of the feeder, which is mainly due to the loosening of the parts of the department. In order to optimize the compression degree of mechanical spring plate compression bolt, it is necessary to adjust the parts so that the inclined groove can reach the range of amplitude specified in production. In the course of using, we should also pay attention not to press the load of silo directly on the feeding trough, which will lead to the long-term fatigue damage of spring plate and connecting fork, leading to one of them breaking.


The quality of vacuum metering filtration system has always been the most important issue for powder manufacturers. Choosing a good filter element is irreplaceable for the production of vacuum metering and environmental protection, so we should also consider some accessories when buying vacuum metering, filter is undoubtedly one of them. How to choose a high cost-effective filter equipment suitable for their working conditions, the following gives you a specific analysis.


We usually choose according to the particle size of materials. For larger particles, filters with higher filtering accuracy can be selected. On the contrary, for smaller particles of powder or nano-materials, it is necessary to select high-precision filters. In this way, the genuine completion of dust-free operation, to achieve the goal of advancing product quality.


Vacuum metering has the following characteristics:

1. It is specially designed and manufactured for plastic and powder production and processing industries. Stainless steel is used for all parts of the machine and material touch.

2. It can be used with extruders of various specifications, high-speed mixers and plastic mixers.

3. Widely applicable to all kinds of powder, granular, recycled crushing materials such as the upper (delivery) use;

4. The feeding height of single machine of this series can reach 2-5 meters, and it can be used in series with multiple machines. The feeding speed of pumping is 1-3 tons per hour.

5. It has the advantages of stable function, convenient maintenance, safety and reliability, saving manpower, etc.

6. High degree of mechanical initiative, filling materials actively, and setting material usage time.
