Problems needing attention when purchasing three roller brake

Compared with other gates, the main advantages of three roller gate are: low cost, high reliability and durability. When selecting the three roll brake, the following indicators should be paid attention to:

1. Reliability: the reliability of the gate is based on the reliability and integration mode of various components of the gate. Selecting good quality components is the basis, such as card reader, controller, display, etc; The integration mode mainly depends on the design and selection of control unit and communication mode. The existence of lightning protection components is also related to the reliability of the equipment.

2. Rotation life: the gate is a moving mechanism, mechanical wear and component fatigue are inevitable, and mechanical rotation life is a key index. Judging from the action mechanism and material selection, of course, it is best to have a formal organization test report;

3. Case material: the gate is used for people's passage. Various external forces act frequently, and the mechanical strength is an important consideration; The gate is a "gateway" for long-term operation and should be beautiful. Therefore, it is necessary to select 1.5-2.0mm stainless steel. Stainless steel is divided into various models, preferably 304 stainless steel.

4. Movement principle: the three-bar movement is the main component of the gate, both mechanical and electric, which are adopted by major international companies. In terms of performance, it mainly focuses on the mechanical life, the pressure borne by the cross bar, the operating noise, the thrust (feel), whether it can be self balanced, whether the parts are easy to replace, etc; In terms of function, whether the lever can be dropped automatically (as required), etc.

5. Glass material above the barcode reader: the upper part of the barcode reader must be transparent. Plexiglass is low cost and easy to process and install. However, after multiple ticket swiping, the glass will be worn and rough, affecting the reading speed and accuracy of the barcode. Therefore, wear-resistant quartz glass must be used;

6. Ticket inspection speed: for the large flow passage of the gate, the ticket inspection speed is a very important index. The ticket checking speed depends on the gate control mode, communication networking mode, ticket checking processing software and mechanical action speed. Generally, the gate response speed is within 500ms.

7. Environmental requirements: in outdoor places, the requirements for humidity and temperature are very high. The gate with complex electronic circuit design is difficult to be applied in outdoor environment. The gate housing can be designed to prevent rain, but moisture condensation and high temperature cannot be avoided. Therefore, it is very important to select moisture-proof and high temperature resistant parts. It is wise to choose a gate with experience in outdoor application.
