When I started vaping in 2008 there wasn’t much choice when it came to vape kits in the UK. But as 2021 approaches, the opposite is almost true – there are so many devices and kits available that it’s hard to wade your way through the myriad of options. What helps, though, is to narrow …
Forging capacity remains high. According to the China Forging Association quoted in the prospectus of Parker New Materials, the forging output in 2015 was 10.05 million tons, accounting for 39% of the global total output, significantly exceeding the share of other countries. In 2020, the output of forgings will reach 13.492 million tons, which has …
There are many common faults of rotating machinery, including imbalance, misalignment, shaft bending and thermal bending, oil film whirl and oil film oscillation, steam excitation, mechanical loosening, rotor blade breakage and falling off, friction, shaft crack, rotating stall and surge, mechanical deviation and electrical deviation.out-off-balanceUnbalance is the most common fault in all kinds of rotating …
The demands of new energy vehicles for weight reduction and efficiency improvement accelerated the improvement of structural integration, the trend of integrated die casting was constantly verified, and the progress of terminal layout exceeded expectations. From the perspective of major automobile enterprises, Tesla was the first to put forward the concept of integrated die-casting. Since …

In mechanical equipment, the application frequency of sliding bearing is relatively high, but it is prone to wear. In the actual application process, the ferrography analysis method can be used to monitor and analyze the composition of the oil sample, so as to find abnormal conditions in time, which is convenient for the mechanical maintenance …
The wear of sliding bearing usually includes scratch, slight wear or severe wear. According to the actual wear condition of sliding bearing, the causes of wear mainly include the following aspects.First, the load is too large. The main function of the sliding bearing is to bear the load. However, if the load it bears is …
Reasons for wear of sliding bearing of main exhaust fan① Read More »
In mechanical equipment such as motors and fans, sliding bearings are very important mechanical parts. The sliding bearing mainly bears the load by using the pressure generated by the hydrodynamic oil film. Its operation nature determines that it may be worn. If the sliding bearing is worn, its working efficiency will also be reduced. In …

Forging is a processing method that can make the blank or ingot produce partial or total plastic deformation under the action of pressure equipment and tools (dies) to obtain parts (or blanks) of certain geometric size and shape and improve their structure and performance. After forging, the metal material has good shape and size stability, …
