How to increase the production rate of industrial aluminum profiles?
In today's situation, whether it is automobile, mechanical protection, or railway, the demand for industrial aluminum profiles is increasing. It is natural to think of the dual problems of cost and resource utilization. How to improve the yield of industrial aluminum profiles has become a top priority. There are many productivity measures. This article talks about two specific and practical measu
NTC thermistor resistance and temperature
NTC thermistor is a type of sensitive components. The resistance value of NTC thermistor generally changes with temperature, which is different from general fixed resistors. It is a type of variable resistor and is widely used in various electronic components. Unlike resistance thermometers that use pure metals, the materials used in NTC thermistors are usually ceramics or polymers.
Gear shaft coupling surface nitriding reasons
The outer sleeve with internal teeth and the inner sleeve with external teeth form a gear shaft coupling, which uses the meshing of internal and external teeth to transmit torque. This type of connection can transmit a large torque and allow a relatively large axial offset, and the accuracy of the installation is relatively low.

High-speed PVC Paper Sticking Machine, it is generally composed of paper feeding mechanism, PVC Paper Sticking Machine mechanism and paper pressing mechanism. The paper feeding mechanism is composed of upper and lower layers, and PVC Paper Sticking Machine is composed of upper and lower layers. Note for high-speed PVC Paper Sticking Machine:
Why vacuum table is also called vacuum spreader
The alias of vacuum table is also called vacuum spreader. It is a very cheap method to use vacuum table to grab products. There are many varieties of vacuum tables. Suction cups made of rubber can generally be operated at high temperatures. Suction cups made of silicone rubber are very suitable for gripping products with rough surfaces.
Operation steps before the large-scale cone calorimeter mahre is prepared for the experiment
The large cone calorimeter mahre is a very precise experimental instrument. A lot of preparatory work is needed during operation. If the preparatory work is not in place or the steps are omitted, the experimental instrument may be damaged. Sex, so you must be cautious when operating
What kind of spring is stainless steel extension springs
Stainless steel extension springs are spiral tension springs that can withstand axial tension. Stainless steel extension springs are generally made of round cross-section materials. When not under load, the rings of stainless steel extension springs are generally tight and there is no gap.
What are the causes of corrosion of bracket bearing parts
Some parts lack marks, use acid corrosion method to supplement words or mark bracket bearing accuracy grade level, etc., the neutralization process is not good and rust occurs.
