Most of the planes have sat and know what it looks like. So have you seen any of the special vehicles that existed on the airfield? Do you know that they are all pretty? It is estimated that even those passengers who often enter and leave the airport have not seen these special vehicles. This article, Xiao Bian let everyone open their eyes, to understand the understanding of those special special vehicles in the airport.
First, emergency rescue vehicle
As an on-site emergency command place, it provides timely support for the collection and reporting of site information, the effective control of developments, the dispatching and command of rescue resources, and the decision-making of event handling to provide technical and equipment support platforms. The role of reliable communication, effective command, and efficient disposal. In accordance with the technical requirements for the national emergency platform system construction, the emergency command vehicle includes an emergency platform integrated application system, a communication system, a computer network system, a video conference system, an image access system, a safety support system, a vehicle modification and foundation support system.
Second, the fire rescue vehicle
Airport fire trucks have the characteristics of faster speed, greater power, and strong off-road performance, and they also have the ability to inject fire extinguishing agents while driving. ICAO clearly stipulates that the response time of airport fire trucks to any part of the airport landing zone should not exceed 3 minutes, preferably not more than 2 minutes.
Three, friction coefficient test vehicle
This vehicle is a special vehicle used by the airport to simulate the aircraft's tire and runway friction coefficient. The friction coefficient test vehicle can output test reports in accordance with the format of airports in different regions, provide accurate values ​​of the lateral friction coefficient of airport runways, and serve as a basis for airport runway maintenance.
Fourth, the bird drive
The airport is equipped with a multi-function bird-drive vehicle. The car is "carried" with two barrels, one short and one long. The long-barrel cannon is called a "gas cannon," and it can make loud noises to "warn" surrounding birds. The short-barrel cannon is called a "shotgun." It needs to be filled with ammunition and is designed to deal with aggressive large birds. In addition, there is a special "sound cannon" on the bird drive vehicle. The bird's-eye signal generator is installed on the car. The operator can select the feared sound according to different birds. No matter what "cannon" is, in fact, it is an "empty rattle," and it is only shocking and not lethal to birds, which meets the requirements of ecology.
Editor's Note: All the models introduced above are all designed to protect the safety and order within the airport and ensure that the aircraft can normally take off. The airport is an important traffic gateway connecting all parts of the world. It is very important to grasp this barrier.
Stainless Steel Precision Casting or Stainless Steel Investment Casting, silica sol process. It is a casting process with little or no cutting. Cast Stainless Steel is an excellent process technology in the foundry industry. Its application is very extensive. Stainless steel cast not only applies to the casting of various types and alloys, but also produces the dimensional accuracy of castings. The surface quality is higher than that of other casting methods, and even castings that are difficult to cast and which are difficult to cast have high temperature resistance and are not easily processed can be cast using investment casting.
In wax pattern process,we mix stearic acid and paraffin wax in wax pattern making,as you know,it is better than polyethylene,and the wax deformation is small.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
In shell hardening process,we use aluminium chloride to harden the shell.This can make the shell so hard that it can`t be distorted,at the same time the bug which the casting may have will be decreased.If there are letters or numbers in it,they will be much clearer.
In dewaxing process,about 95% of the castings suppliers adopt the original water dewaxing technics,but we using the advanced steam dewaxing technics,which we are very proud of.This can effectively avoid the air-hole and sand-hole,making the casting look much nicer.
In smelt process,we use middle frequency furnace,avoiding the emergence of the oxide; in molten steel control part,we use Germany-imported direct reading spectrometer machine,assuring its quality before the molten steel out of the furnace.During this process we use ERP production and management software to get the feedback information.
In shell-knock out process,we have special machines,which can decrease the hitting and knocking, easily made by manual shell knocking out.
In shot-blasting process,we have crawler-type and hanging shot-blasting machine,with steel shot 0.5-0.8,making the products smooth.Of course,if the customer wants it look much nicer,we also can carry out sand-blast treatment.
In heat treatment process,we use electric furnace,and adopt double-temperature control in order to heat the products equally.As a result, the products will have great metallurgical structure.
Our tolerance can reach at the grade of 5-7 according to our country`s tolerance standard.
In machining process,we have 12 CNC machining centers and some other machines, so we can make further machining if the customers need.
Products in stainless steel cast factory divide into Pump Valve Accessories Casts, food machinery casts, and architectural hardware casts.
