What to do if the transformer of the swing screen fails
The swing screen is a vibrating screen, which is suitable for screening granular and powder materials. Its processing capacity is relatively high, its working mode is close to manual screening, and its principle is easier to understand, so it has become the equipment of many manufacturers. Swing screens can be used in many industries, such as medicine, industry, mining, etc. The size of the screen itself can be customized according to needs. It is mainly a high-efficiency vibrating screen specially designed to meet the needs of large-scale industry. Large quantity, high-precision screening.
The swing screen has few maintenance times and can work normally under normal conditions. However, problems may still occur during long-term use, such as bearing heating and transformer failure. Bearing heating is a problem that all vibrating screen equipment will encounter. Lubricants need to be replaced frequently to maintain its service life. Transformer is a unique configuration of the vibrating screen, and winding and core faults are common faults of the gyratory transformer. When the power transformer operates stably, the magnetostriction of the silicon steel plate will cause the core vibration. The winding will also be compressed under the action of load current and electric field. The displacement condition is closely related to the vibration of the transformer surface. According to this idea, when the transformer fails, we can quickly find the exact cause and prevent it.
When the transformer of the swing screen is offline, add low-voltage excitation signal and power frequency sine signal on the high-voltage side respectively, and then measure the vibration signal of the transformer surface.
Operating principle of swing screen
YBS series vibrating and swinging screen is a low-frequency rotary vibrating screen imitating manual shaking. The principle is that the instantaneous motion is the combination of the radial displacement and the circular motion with this displacement as the axis (spiral motion). The exciter, which can adjust the eccentricity, produces a nonlinear three-dimensional motion, and the material also produces the same motion similar to manual operation, so as to achieve the purpose of screening. A more ideal screening effect can be obtained by combining with screening accessories. It is suitable for materials with spherical, cylindrical, flaky, or even irregular shapes that are easy to block the screen and require precise screening.

Technical characteristics of swing screen
1. The design is exquisite and the structure is good, which is conducive to improving the service life of the equipment and reducing the operation and maintenance costs.
2. Low frequency, low load operation, the power system has little effect on equipment and materials.
3. The equipment is relatively small in size, light in weight, simple in installation, convenient in maintenance, low in power consumption and noise pollution.
4. The relative processing capacity is large, the screening efficiency is high, and the screening accuracy of the swing screen is generally above 95%.
5. Fully enclosed structure, good sealing effect, and basically no material dust pollution.
6. The discharge port can be adjusted freely within 360 ° circumference for process layout.
7. The screen is easy to replace and can meet the dry and wet classification requirements of general materials.
8. The screen surface can be conveniently equipped with a screen cleaning device to solve the problem of screen surface blockage.
Up to 5 times the output per unit area; It can be separated to 6 levels, and the screening accuracy is up to 90% - 95%; With the use of silicone rubber ball and ultrasonic screen cleaning device system, the screen hole will not be blocked. Closed dedusting, the acceleration is 4.5 times lower than that of the vibrating screen, and the service life of screening parts is improved while maintenance is reduced; Noise<75dB. Optimize the gravity balance, and the dynamic load of the foundation is low.

Processing process
Production workshop
This is our inner workhouse.
some small equipment or parts will be made from here.
There are cranes, laser cutting machines, electric welding machines, platen machines, angle grinders, polishing machines, forklifts, and other equipment.
Packaging & Shipping
After you place the order and pay the deposit, we will start to arrange the production and contact the ocean freight transportation agency to reserve the position. Two days before the end of production, you need to complete the final payment. Then, we inform the ocean cargo transportation agent company that it is ready to come to the factory to pull the goods to the port. On the day of delivery, we will send the customer the factory video and pictures, and mark the corresponding English name of each product and product parts with a marker to prevent the customer from not knowing what each part is after receiving the goods. At the same time, we will put the English version of the product instructions in the cargo box. We generally select freight forwarders with preferential prices for customers to deliver goods for you. The shipping method can be FOB or CIF. You can also choose EXW, and then contact the goods agent company yourself.
