How many turns to put the washing machine?

Modern washers impress with their speeds and capacities, but the high values ​​on the label logically increase the cost of the unit. Especially when it comes to spin. Along with the usual automatic machines with push-ups of 1000-1200 rpm, there are also models that can accelerate to 1800 and even 2000 rotations. But is this race really necessary, is the wear and tear of the parts intensified, and are all the fabrics able to withstand such loads? We propose together to figure out how many revolutions to put in the washing machine program for a safe and efficient cycle.

What determines the choice of revolutions?

Most washing machines offer the user to independently adjust the spin speed until the function is completely canceled. This is due to the need to "tune" the washing machine under the laundry located in the drum. Since cotton products and things made of mixed fabrics can easily withstand a load of 1000 revolutions, and delicate materials, silk, wool, polyester, are deformed if the push-up occurs at a mark above 400.

The user can independently adjust the number of spin turns depending on the type of fabric of the clothes to be washed.

But the main boundaries are set by the manufacturer. The optimal maximum speed and minimum depends on the capabilities and power of the machine. How to determine what the washing machine is capable of, we will tell further.

Speed ​​features cars

To find out how well the machine wringes out, the consumer will be helped by the wringing class affixed to the factory label. There are only seven of them - A, B, C, D, E, F and G, where “A” is considered better and “G” is considered the worst. The levels are assigned to the unit depending on two parameters: the residual moisture of the laundry and the optimal number of revolutions per minute.

First of all, attention is paid to residual moisture. In other words, specialists measure how dry the laundry has become after the spin cycle. The calculation is simple: first things are weighed before washing, then after the drum has stopped completely. Then the smaller is subtracted from the larger, and the result is divided by the “dry” weight and multiplied by 100%. The resulting percentage will show the degree of dryness of the fabric and reveal the spin class:

• up to 45% - A;
• up to 54% - B;
• up to 63% - C;
• up to 72% - D.

Residual moisture in models of class E, F and G is wrung out by about 15-20%. Due to the low spin power, these washers are almost completely discontinued and are not on sale.

But chasing cars with the mark "A" or "B" does not make sense. In fact, the gap between the percentages only seems to be large, but in reality they are equally wet things. The difference is only in a few additional hours of drying, while the washing quality remains at the same level. For what the washing machine is bought.

In addition to residual moisture, the maximum allowable number of revolutions per minute also affects the push-up efficiency. That is, how quickly the engine spins the drum to release moisture. The higher the indicator, the greater the speed and closer the coveted spin class of level “A”. And if earlier the mark of 1000-1200 rotations was considered amazing, now some machines can accelerate to 2000. A vivid example is the Gorenje WA 65205 model, which offers the most powerful engine and drum performance.

It is proved that the higher the spin speed, the less hardness salts remain in the fabric fibers and the laundry becomes softer.

Another question is whether space velocities are needed or is a sufficiently average value of 1000 revolutions? We illustrate the scheme of the spin process. It begins immediately after draining the water after rinsing. The engine after stopping starts to increase power, gradually gaining momentum. At the same time, the drum is unwound, and the laundry located in it is pressed against the walls due to centrifugal force.Moisture is pushed out of things and out through the holes out into the tank. The laundry is dried, and the separated liquid, gradually accumulating, is pumped into the sewer with a pump. By the end of the program, the speed reaches its maximum and holds for 2-3 minutes, after which the system slows down. Thus, the indicated 2000s are achieved for a couple of minutes.

Is a high spin speed really necessary?

It is widely believed that excessive revolutions affect the life of the washing machine. More specifically, it is believed that if the machine can withstand strong acceleration, then its design and parts are stronger and more reliable. But now experts say that this is a myth.

At the moment, there is no direct relationship between the maximum withstand speed and the reliability of household appliances. Even bearing in mind that strong acceleration requires strong parts, we must not forget that at the same time the general loads and wear of spare parts are amplified. Therefore, less stable components of low-speed machines, not subject to rotation at 2000 rpm, do not deviate from more advanced competitors. So, units with a maximum of 600 revolutions work properly for 7-10 years.

Much depends on the manufacturer and the quality of the materials used. It is the brand that sets the period of trouble-free operation and assumes warranty obligations. True, previously announced numbers are revised over time. A striking example will be the company "Ariston", which reduced the term of manufactured equipment from 10 to 7 years. There were no official statements, and it was felt that the decision was influenced by complaints from consumers and the desire of the company to "hedge". Most likely, the point is the use of low-quality spare parts in order to reduce the cost of production and increase demand.

High-speed washing machines are prestigious and expensive, but in everyday life their use is doubtful. As a rule, if you want to quickly dry the laundry, the consumer will use a dryer or an iron, and with standard hanging things 20-30% humidity does not play a role.
