What is the difference between a single-core wing gate and a double-core wing gate?

February 11 00:06:52, 2024


The most important difference between a single movement and a double movement is that the single movement is one-way, and the double movement is two-way.
As a kind of channel management equipment, the most essential function of the gate is to pass only one person at a time through blocking and release. The application object is pedestrian, the application is the entrance and exit, but as part of the intelligent channel management system, the gate can be combined with other The system works together for different special occasions to play a greater role.
According to the different control methods of the movement, the gate can be divided into mechanical, semi-automatic and fully automatic. Some manufacturers refer to semi-automatic as electric and automatic as automatic.
The mechanical type controls the movement of the blocking body (connected to the movement) by manual control, and the mechanical limit controls the movement of the movement;
Semi-automatic is to control the movement and stop of the movement by electromagnet;
Fully automatic is to control the movement and stop of the movement through the motor.
The opening and closing of the blocking body is further controlled by controlling the movement and stopping of the movement.
According to the number of movements and blocking bodies included in the same gate, the gate can be divided into a single movement (including one movement and one blocking body) and a double movement (including two movements and two blocking bodies). , in a bilaterally symmetric form).
There are many styles of gates such as three-roll gate, swing gate, wing gate, one-word gate, translation gate, rotary gate, barrier-free passage gate, etc. At present, there are three roller gates, swing gates, and wing gates that are common in the market. Three kinds.
Wing gate is one of the channel management equipment. The wing gate is mainly used for pedestrian channel management. It has the characteristics of quick opening, safety and convenience. It is an ideal management and guidance device for pedestrians with high frequency access and passage; it is widely used in airports and subway stations. Stations, docks, scenic spots, parks, pedestrian walkways, etc., can cooperate with smart cards to realize offline ticket sales management system functions, and form unattended management of personnel access.
Three-roll gates are commonly used for easy disobedience level access control in public access. Widely used in the factory's attendance system, the consumption system of the business unit, the access control of the community, the ticket inspection system of the venues, and the palm-shaped system management of the construction site. Available in a variety of configurations, it can be used in all built environments and solves all control problems in pedestrian access. Different identification systems can be configured (ID card, IC card, barcode, palm shape, fingerprint, iris, etc.).
The swing gate is externally equipped with a standard electrical interface, which can be easily connected to a variety of card readers. The column swing gate is a common application equipment for pedestrian walkways. Under normal circumstances, the column swing gate is composed of two single swing gates to form a channel application. The column swing gate can also be used stand-alone if conditions permit.

Closed Cooling Tower

Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.

First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.

Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.

Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.

To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
