How to achieve effective control and management of personnel access? The core equipment that usually needs to be selected in the channel control design is a pedestrian channel gate that directly communicates with the access controller. The types of manway access gates available for selection are: semi-high revolving doors, fast-passage three-roll pedestrian walkways (also known as triple-roll gates) and full-height doors (also called full-height swing gates, turnstiles). Then, how to use the most suitable pedestrian access gate product within the appropriate budget to achieve the best channel access control effect? The following points must be taken into account in the selection of access control gates for pedestrian control equipment:
1. The site use environment of the pedestrian access gate;
2. The user's use requirements;
3. The number and flow of people through the pedestrian access gate;
4. The special features that need to be implemented.
How to choose pedestrian access gate? When purchasing pedestrian barriers, it is not always necessary to select the most expensive or best product that is suitable for use in the right budget. The following takes a factory as a channel control device as an example. The pedestrian gate should be selected based on the following conditions to explain how to choose pedestrian access gate products. The specific environment for pedestrian access gates is listed below.
Pedestrian access gate installed at factory gate
The factory has a total of 3,000 people. 1000 people per shift
All shuttles arrive within 10 minutes
1. Consider the speed of use.
Prevent the phenomenon of waiting for a long time while commuting. 1000 people per shift. 100 people need to pass every minute; all within 10 minutes. Three-roll pedestrian access gate speed 15-25 person/minute. Calculated according to 20 people/minute; actual time depends on usage habits and access control system response time. Ensure that there will be no conflict between people entering and leaving the shift. At least 5 three-roll pedestrian walkways are required. The frequency of use of three roller gates close to 100% during work hours
2. Consider the frequency of use of pedestrian access gates.
Pedestrian access gates of attractions will use the difference in the frequency of the use of pedestrian access gates between factories and attractions at various times of the day; the factory pedestrian access gates are used most frequently when commuting. The frequency of use during rush hours will be close to 100% if 5 three-roll pedestrian walkways are used. If using a 100% frequency machine. But if you use 40% of the frequency of equipment, five devices can meet. Need more than 13 units; play an appropriate role. The right product is used in the right place. Reduce future equipment maintenance and update costs.
3. Consider the service life of pedestrian access gates.
Assume that 5 devices are used. Each machine works 1200 times a day and each person goes in and out once a day. It works about 400,000 times a year; it selects equipment with a lifespan of less than one million. In less than a year there will be major area failures of major components, the overall life expectancy of 2-3 years. Need to be replaced; choose a faultless operating frequency of 300-500 million devices. The overall life span is more than 10 years; the main components can work without failure in 5-10 years.
4. Consider the aesthetics of pedestrian access gates.
Semi-open use depends on the sea city. General use case data, spray paint spray roll three-roll gate caution. Better to import or higher; at least AISI 304 stainless steel. Internal antiseptic handling material thickness. Water chestnut processing. Wire drawing processing.
Large flow of people. In the event that the requirements cannot be met, there is not enough space for the brakes. You can consider choosing a fast-channel product. Faster lanes are more beautiful, faster, safer, and more convenient than gates. Although the price is more expensive, it is widely used because of price barriers. However, in the more advanced foreign-funded factories, the fast-track is destined to become an increasingly popular product, which plays an important role that can not be replaced by pedestrian barriers.
Solenoid Armature makes an very important role in complete Solenoid Valve compared to other solenoid valve parts, so the quality of the armature directly related to the life of complete solenoid valve. Hereby, let me introduce how we control armature quality from character of raw material and how we produce during production.
We also called solenoid armature as solenoid valve armature, solenoid valve stem, solenoid valve core, solenoid Plunger Tube Assembly, solenoid armature tube assembly, Solenoid Armature Assembly, Electromagnetic Valve armature, etc, but all in all, the solenoid armature looks like an opener and closer even like a head in the solenoid valve.
The armature can be divided into four parts roughly, they are fixed core(who with or without shading ring depending on DC or AC voltage type), plunger tube and tube base(has option of stainless steel and brass), mobile plunger(installed with inner and outer spring, top and bottom seal).
The fixed core and movable plunger are made of high magnetic stainless iron, such as 430FR, has good performance of attraction and rust-proof. During production, we doing inspection after each procedure.
The plunger tube is made of H62 brass or seamless 304 stainless steel, the wall thickness from 0.20mm to 2.5mm available. All raw material is inspected before put them into our warehouse.
The plunger tube base is made of H59 brass or 304 stainless steel, with high performance, also we inspected each lot before put them in warehouse.
According to application requirement, choose suitable welding to connect each part, such as laser soldering, argon-arc welding, silver soldering.
The seal can be NBR, Viton, EPDM, Silicon, Teflon, etc. All can be customized as your requirement.
Except this,we also sale for Auto Drain Valve , Air Suspension Valve ,solenoid armature assembly, Forged Brass Valve .
Welcome your any inquiry, we can produce as per your requirements.
