CNC Vertical Machining Center
According to years of
production and sales experience, combined with user feedback, we have
made various humanized designs.VTC80 is applied to rough and finish
machining of auto wheel hub, brake hub, flywheel housing, clutch
housing, pressure plate, rim, differential reduction housing, disc and
other parts. This machine can be equipped with CNC system by user's
option. It realizes strong cutting performance in structure, super heavy
load on the table, high dynamic and static rigidity of the machine,
safe and stable all movements, long service life and high machining
efficiency.

1. The configuration of the radiator is very important, if the configuration is not appropriate, the heating effect is not good. Radiator configuration should be determined according to the room area, orientation, envelope structure, function and other factors, such as: the design of the heat load of the shady room is larger than that of the sunny room, and the number of radiators should be more; The temperature of the elderly and children's rooms needs to be higher, and the radiators must be equipped with more. If the radiator's heating index (heat sink's heat dissipation capacity) is less than the amount of heat lost in the room per hour, then the heating effect can be imagined and will not be warm.
2. How to determine the radiator configuration is not enough? Here is a simple calculation method: For the use of traditional horizontal radiator, double ride (before and after the two count a column), each column heating capacity of up to 1.0 ~ 1.1 square meters, single Take half the heating capacity. Never mislead some radiator distributors to mislead.
3. Whether the heat sink is selected to match the installation method. The radiator inside and out of the installation mode is different from the internal structure of the radiator that is installed under the next installation method. When the order is purchased, it should indicate which installation method is adopted, otherwise the heating effect will be affected.
4. Is the design of the piping reasonable? The design of gas heating for boilers is not the same as the piping design for centralized piping. The design of pipelines should follow the following principles: principle of shortest pipeline, principle of water flow balance, matching of pump lift flow, etc. In addition, the design of piping should be designed to avoid the design of "U" shaped pipe. Some unreasonable due to the design of the pipeline, resulting in the hot floor upstairs is not hot, or open some radiators, other radiators are not hot, or the end of the front of the hot end is not hot and so on. Due to the unreasonable design of the pipeline, boiler load may increase, noise may increase, frequent start-up, no flameout, no automatic start-up, etc. Even boilers may not work properly. Therefore, it is important to choose a professional HVAC company.
The so-called "U" shaped pipe structure is to avoid bypassing the door frame as much as possible, otherwise it will form a "air blockage" and affect the circulation of the water pump, thereby affecting the heating effect and the normal operation of the boiler. In the above situation, it is better to cut the groove and install the pipe. If it cannot be avoided, it is necessary to install an automatic exhaust valve at the highest turning point of the pipeline (inlet and return). Here is to explain that many automatic exhaust valve quality is poor, it is difficult to play the role of automatic exhaust.
For unavoidable pipelines with long pipelines, the pipeline's circulation capacity is not good, because the physical capacity of the lift-to-flow curve of the built-in water pump has been exceeded or approached. In this case, synchronous self-flow should be installed on the pipeline. The water pump, or a circulating water pump driven by a relay driven by a signal line from a boiler. At this point, it should be noted that the flow and speed of the two pumps should be the same or almost the same.
5. Warning: The most reasonable piping design uses down-in and down-out installation methods. The heat sink is higher than the inlet and return pipes.
