What is the reason for the small amplitude of the ultrasonic vibrating screen?

As a mechanical equipment, there will always be a certain amount of loss after long-term use, and the vibration amplitude will also be affected.

There are several reasons for this.

1. Screen problem: the ultrasonic vibrating screen screen is not tightened when loading the screen or the screen is glued to make the amplitude smaller.

2. Transducer problem: If the ultrasonic grid and the transducer are not locked, the amplitude will be reduced.

3. Resonance problem: the vibration motor or screen frame is damaged or cracked, resulting in frequency misalignment and small amplitude.

4. Connection cable problem: Ultrasonic screening system is an important screening system of ultrasonic vibrating screen, which is composed of: ultrasonic power supply and ultrasonic transducer. However, it is the cable that connects the ultrasonic power supply and the transducer, and if the cable insulation measures are not done properly, the amplitude will be reduced.

The reasons for the small amplitude of the ultrasonic vibrating screen are:

Screen, resonance, ultrasonic sieving system cable connection, ultrasonic transducer.

1. The ultrasonic vibrating screen screen is not tightened or the screen is glued to make the amplitude smaller.

2. Resonance: The vibration motor or screen frame is damaged or cracked, resulting in frequency misalignment and small amplitude.

3. Cable of ultrasonic screening system: Ultrasonic screening system is an important screening system of ultrasonic vibrating screen, and it is a cable that connects the ultrasonic power supply and the transducer, if the cable insulation measures are not done, the amplitude will be reduced.

4. If the ultrasonic grid and the transducer are not locked, the amplitude will be reduced.

Solutions for small amplitudes:

1. Screen problem: You can check whether the screen is tight and open the glue by hand, if you find that there is no tension or open the glue, the screen should be removed from the new stretch.

2. Resonance problem: You can check the motor or screen frame, if you find a crack, you should stop the machine immediately and contact the manufacturer for maintenance.

3. Connecting cable problems: You can check the insulation value of cables and plugs, and solve problems in time.

4. Transducer problem: You can carefully check the contact parts between the grid and the transducer, and clean up the foreign objects thoroughly if they are found.

Improve the flattening (light contact between powder and the mesh port) and slip effect of low-density powder in gravity sedimentation, improve the retention or wedge of high-density metal in the mesh port, and solve the screening problems such as strong adsorption, easy agglomeration, high electrostatic, high precision, high density, light specific gravity, etc., with superior performance!

Achieve a big breakthrough in the performance of ultrasonic vibrating screen, so as to improve the screening efficiency and screening quality. Expressed by the screening pass rate, in general, the pass rate is increased by 50%-400% compared with the non-ultrasonic vibrating screen.

1: While achieving high-precision and high-mesh screening, a narrow particle size range is controlled

2: It can be used in single layer and multi-layer, and a set of intelligent ultrasonic generator can use three transducers at the same time

3: Thorough screen self-cleaning function: more than 500 mesh screening, no mesh blockage, no screening efficiency attenuation;

4: Solve the screening problems such as strong adsorption, easy agglomeration, high electrostatic, high precision, high density, light specific gravity, etc

5: Ensure that the characteristics of the materials handled remain unchanged;

6: The screening accuracy can be increased by 1-100%, and the output can be increased by 1-8 times

There are many factors that affect the amplitude of an ultrasonic vibrating screen. We can analyze it from both hardware and software aspects.

Hardware factor: The so-called hardware factor refers to the fact that the maximum amplitude of the ultrasonic generator does not match the production demandAnother reason is that the adjustment of the eccentric block of the vibrating motor does not meet the production requirements. For this reason, the user can directly contact the vibrating screen manufacturer and ask them to send a technician to the site to re-debug the eccentric block or replace the ultrasonic generator

Software factor: The software factor that affects the amplitude is mainly the tightness of the screen. Once the screen is relaxed, it will directly affect the amplitude of the ultrasonic vibrating screen.

There are two reasons that affect the tightness of the screen. First, the vibrating screen manufacturer is not tight when producing ultrasonic vibrating screen. Another factor is that due to the large amount of one-time feeding in the process of use, the screen is in a state of tension for a long time, and the screen will be relaxed or even damaged in the long runThe above factors can be used by the user to weigh the ultrasonic vibrating screen screen.

In the production process, the amplitude can be avoided by feeding the appropriate amount of material according to the operation requirements each time.

The reasons for the small amplitude of the ultrasonic vibrating screen are: the cable connection of the screen, the ultrasonic screening system, the resonance and the ultrasonic transducer.

1. The screen is not tightened or the screen is glued when the screen is loaded, and the amplitude is reduced

2. Ultrasonic screening system cable: The ultrasonic screening system is an important screening system of the equipment, and it is the cable that connects the ultrasonic power supply and the transducer. If the cable insulation is not done well, it will also lead to a decrease in amplitude;

3. Resonance: There are cracks or damage in the screen frame or vibration motor, resulting in frequency misalignment and small amplitude

4. Ultrasonic transducer: If the grid is not locked with the transducer, the amplitude will be reduced.

Solution: 1. For the screen problem, check whether the screen is open and tightened by hand, if it is found that the glue is open or not tightened, the screen will be removed from the new stretch and tightened;

2. If there is a problem with connecting cables, carefully check the insulation value of cables and plugs, and solve problems in time if they are found;

3. Ultrasonic transducer, check the contact part between the grid and the transducer, and clean up the foreign body if it is found;

4. If there is a resonance problem, check the sieve frame or motor, and when a crack is found, immediately stop the machine and contact the ultrasonic vibrating screen manufacturer of Huanxin Machinery to send relevant technical personnel for maintenance and testing.

Check if there is a problem with the ultrasound connection;

The angle and excitation force of the vibrating screen motor are reasonably adjusted.

The causes and solutions of the vibrating screen when the ultrasonic vibrating screen is used are as follows:

Solution: The lack of oil in the motor will affect its operation, and once the lubricating oil consumption is serious, the friction of the motor components will increase and reduce the vibration force. As soon as it is found, it should be stopped immediately to add lubricating oil.

2.The reason for the cleaning device: for the stainless steel ultrasonic vibrating screen, the rotary vibrating screen does not understand that the user's material cleaning device is also the second power source to provide vibration force, once the transducer is overheated or the ultrasonic power supply can not operate normally, the vibration force can also be reduced.

Solution: The inspection standard is: the normal temperature of the transducer is 60 when it is running, if the temperature is abnormal, it should be shut down for maintenance (mainly due to material residues, so the contact between the transducer and the screen should be cleaned before the operation of the sieve machine)!

Adjustment of the amplitude of the ultrasonic vibrating screen.

The amplitude of the ultrasonic vibrating screen has generally been adjusted by the vibrating screen manufacturer when leaving the factory, and the sieve machine can be directly connected to the production workshop for use. This advantage is that in the future production, the operator can not adjust the amplitude arbitrarily, which will affect the normal production. But there is also a disadvantage, that is, the screening material is single.

How can we reasonably adjust the amplitude of the ultrasonic vibrating screen according to the characteristics and output of the material?

First of all, we need to understand what we do to adjust the amplitude. The adjustment of the amplitude of the ultrasonic vibrating screen is related to the output and accuracy of material screening. The amplitude can be adjusted in 3 stages, from low to high.

Low amplitude: mainly used in materials with a heavier proportion of materials, and materials with good fluidity, there is no need to make the material jump very high;

Medium amplitude: It is mainly used for screening with general materials, which can not only make the material not block the net but also prevent the material from jumping very high;

High amplitude: It is mainly applied to materials with light specific gravity, very large viscosity, and static electricity, so that the materials do not stick, and the materials are broken up by the high amplitude of ultrasonic, so as to be more conducive to the screening of materials.

Ultrasonic vibrating screen eccentric block adjustment.

1. The weight of the eccentric block: increasing the weight of the eccentric block (increasing the weight of the auxiliary eccentricity) can increase the amplitude of the ultrasonic vibrating screen, the lower eccentric block controls the upper and lower amplitude of the sieve machine, and the upper eccentric block controls the left and right amplitude of the sieve machine;

2. The angle of the eccentric block: adjusting the angle of the eccentric block can control the running trajectory of the material on the screen, and the specific adjustment angle can refer to the manual of the ultrasonic vibrating screen that is attached with it and adjust it according to the characteristics of the material.
