The Size And Production Capacity Of The Spinning Plant Should Be Improved.

Today's new Spinning equipment Higher requirements for spindles are put forward.

The number and speed of spindles have a direct impact on the production capacity of the corresponding processes, especially the spinning spindles, which are used to represent the size and production capacity of the spinning mills in terms of their quantity. Now the new spindle has reached 25000 turns per minute. If the old traditional spindle 7.8 exceeds 15000 turns, it will face a lot of power consumption and noise. Spindle life Further shorten the yarn quality and other practical problems. Now let's take a look at the basic requirements of new spindles.

Spindle speed should reach 25000 rpm, or even more.

At high speed, the spindle requires low noise.

3. The speed of spindle belt should be within the normal range. It is not necessary to increase spindle speed by increasing spindle tension.

(4) when the spindle is running at high speed, spindle The vibration is small.

At any normal spinning speed, the spindle energy consumption is low.

If we want to achieve the above five requirements, we must first reduce the diameter of the spindle, so that the speed of the spindle belt can be reduced. To reduce the diameter of the spindle, we should first reduce the diameter of spindle bearing and the diameter of spindle. However, after reducing the diameter, the spindle should also bear the changing force (normal speed and maximum speed) caused by the change of spindle speed without bending and breaking. This depends on the selection of high quality steel and precision machining technology.

At the same time, the spindle bar needs to be shortened to get enough tough performance, and the bearing parts and the bottom of the spindle need to be redesigned due to the decrease of spindle diameter. In order to meet the needs of high-speed operation, the spindle vibration absorption system is also strengthened. In view of the above requirements: spindle manufacturers at home and abroad show great powers and have done a lot of work.
