Which is very necessary to understand the project planning program to determine the nature of the project. The nature of the project determines the program of the process, such as to determine the project is a production plant or logistics center; is a food project or pharmaceutical project or other projects and so on. Understanding these circumstances is crucial to understanding the production and storage environment requirements. Because these factors are directly determined by the form of the door, size, opening and closing speed, frequency of use, airtight performance, thermal insulation performance.
5. Understanding the production and logistics process
Master the interrelationship between the regions, configure the appropriate equipment. Such as: how to use the door process? The type of vehicles passing through? Is there a need for the passage of personnel? How to ensure safety?
6. The door of the choice of control mode
is to determine the efficiency of a passageway operation is an important factor. We have to consider in this passage. Need to control how to open and close the door, at the same time to ensure that the channel is smooth and efficient, but also to ensure that the operation of the safety and convenience. And sometimes also need to consider the communication and linkage function between the doors or and the central control center. So the selection of the appropriate control method is to allow the door to play its maximum function of one of the important factors. A good door only configured to meet the logistics process requirements of the control system in order to maximize its role.
7.Determining the door varieties, models, quantities, specifications
In fact, this is often overlooked a problem. The form of the door can be different, the number of doors should be designed in conjunction with the characteristics of the process, and a certain degree of foresight. Doors are also controlled in different ways, so set in stone, or a thousand changes may be counterproductive. Must be based on the characteristics of the company to make targeted choices, it is possible to make the best program to.
