  • 4. The average flow rate of the pipeline is too low, and the average flow rate of the pipeline is lower than the critical settlement deceleration, resulting in pipeline blockage and unable to transport slurry normally. Through the above examples, it can be seen that the selection of ZJ series slurry pump is more complicated, and if any link makes a mistake, it may lead to the mistake of the entire selection, causing irreparable losses to users, and having an adverse impact on their reputation. Therefore, in the selection, we must pay attention to the values of several key coefficients and calculate them carefully to achieve accuracy, so that the ZJ series slurry pump can fully reflect its advantages in field application.

    8. It is worth mentioning that aluminium window joinery has not always been so popular. Until recently, it was regarded as cold joinery, and there was a lot of truth in that. Therefore, whilst aluminium was used in warehouses, offices and shops, it was not used in single-family homes. Nowadays, the situation is quite different – of course, aluminium does not feel as ‘warm’ as wood and, when the frame comes into contact with a warm hand, it will feel cooler than, say, pine. This is all due to the fact that aluminium does not have as much ability to absorb heat. However, we should add that in reality its temperature will often be the same as that of the aforementioned wood.

  • Material of Aluminium Window Profile

  • The aluminum profiles for doors and windows are made of 6-series aluminum alloy, and the aluminum-magnesium silicon is the main element of the 6-series aluminum alloy, and each element has a certain range of content. However, the price of various elements is inconsistent, and the lack of precious metal content is a major cause of poor profile quality. Only in strict proportion then can produce aluminum extrusions of excellent quality. The prepared raw materials are placed in an aluminum melting furnace to be melted, slag is discharged, cooled, and then cast aluminum ingots or bars are used for the production of aluminium profiles. If the exhaust is not ideal, the air bubbles in the aluminium profile will cause defects. The aluminium profiles for doors and windows are mainly made of 6063 grade aluminum alloy. If the aluminum extrusion manufacturer uses the national standard 6063 aluminum ingot, it will be guaranteed in terms of raw material quality.
