Washing machines are already our essential home appliances for the 21st century. Whether in large cities or rural areas, almost every family will have one. It gives us too much convenience, not only saves time and effort, but also requires a simple operation to clean our clothes. Its price is not expensive, it is also about 1,000 yuan. However, if the washing machine malfunctions, it will be more troublesome. It is not like a small household appliance that can be thrown by itself and requires professional personnel to carry out repairs. Next we come together to understand the washing machine troubleshooting methods and washing machine maintenance guide it! Washing machine fault repair method Let's start with an example of a common failure. Sometimes when we wash our clothes, the washing machine often emits some noise. If this is the case, you must stop work immediately and turn off the power. First check if there is foreign matter in the lower garment pocket. If there is no foreign object, it may be the clutch or the motor is damaged and needs to be replaced. Washing Machine Maintenance Guide 1 Before we wash our clothes, we must carefully check whether there are money, coins or some items in the trousers pockets of the clothes. In some cases, we must remove the trousers in a timely manner to avoid jamming in the washing machine during operation and affect the work. This can easily damage the washing machine. If your clothes contain metal buttons, etc., you need to turn the clothes over and wash them again. This will protect your clothes and will not affect your work. Washing Machine Maintenance Guide 2 When we add clothes to the washing machine, we don't have to be overly iconic, let alone fill the washing machine. If it is too full, it will increase the burden on the motor and shorten its service life. Dark and light-colored clothes are best washed separately so that they do not stain. If you have a tie or something, it's best to separate them, because it's easy to knot with other clothes and affect the washing machine. Washing Machine Maintenance Guide 3 After completing the work, you need to unplug the power supply and turn off the water tap switch. If there are some sundries in the airframe, you need to clear it in time to avoid affecting the next work. For the filter, it is best to clean it once a month, so that it can remove debris in time. Xiao Bian's words: If it appears to be a bit troublesome, it not only requires a professional master to repair it, but also has to spend some money. If we usually maintain it, it will reduce the occurrence of failure and extend its useful life. And if conditions permit, it is best to put it in a ventilated place. After reading this article, I believe you will have a deeper understanding of the maintenance of the washing machine. The above is a troubleshooting method for washing machines shared by Xiao Bian today and we hope to help everyone.

Sintered NdFeB magnets are prepared by the raw materials being melted in a furnace, cast into a mold and cooled to form ingots. The ingots are pulverized and milled; the powder is then sintered into dense blocks. The blocks are then heat-treated, cut to shape, surface treated and magnetized.
As of 2012, 50,000 tons of neodymium magnets are produced officially each year in China, and 80,000 tons in a "company-by-company" build-up done in 2013. China produces more than 95% of rare earth elements, and produces about 76% of the world's total rare-earth magnets.
Neodymium magnets are graded according to their maximum energy product, which relates to the magnetic flux output per unit volume. Higher values indicate stronger magnets and range from N35 up to N52. Letters following the grade indicate maximum operating temperatures (often the Curie temperature), which range from M (up to 100 °C) to EH (200 °C).
Sintered Nd2Fe14B tends to be vulnerable to corrosion, especially along grain boundaries of a sintered magnet. This type of corrosion can cause serious deterioration, including crumbling of a magnet into a powder of small magnetic particles, or spallingof a surface layer.
This vulnerability is addressed in many commercial products by adding a protective coating to prevent exposure to the atmosphere. Nickel plating or two-layered copper-nickel plating are the standard methods, although plating with other metals, or polymer and lacquer protective coatings are also in use.
Neodymium magnets have replaced alnico and ferrite magnets in many of the myriad applications in modern technology where strong permanent magnets are required, because their greater strength allows the use of smaller, lighter magnets for a given application. Some examples are:
ï‚·Head actuators for computer hard disks
ï‚·Magnetic resonance imaging (MRI)
ï‚·Mechanical e-cigarette firing switches
ï‚·Locks for doors
ï‚·Loudspeakers and headphones
ï‚·Magnetic bearings and couplings
ï‚·Electric motors:
ï‚·Cordless tools
ï‚·Servomotors
ï‚·Lifting and compressor motors
ï‚·Synchronous motors
ï‚·Spindle and stepper motors
ï‚·Electrical power steering
ï‚·Drive motors for hybrid and electric vehicles. The electric motors of each Toyota Prius require 1 kilogram (2.2 pounds) of neodymium.
ï‚·Actuators
ï‚·Electric generators for wind turbines (only those with permanent magnet excitation)
ï‚·Direct-drive wind turbines require c. 600 kg of PM material per megawatt
ï‚·Turbines using gears require less PM material per megawatt
