Zhang Zhanhao Beijing Knoxenhua Flooring Co., Ltd., 100068 compressed air is widely used in wood processing plants. In addition to being the pneumatic control power of mechanical equipment, there are many applications that will be introduced in this paper. Compressed air is simple to manufacture, and the price is low. The compressed air pipe is only about 0.1 yuan cubic meters. It is very simple and has various colors. It can be bent freely without welding. It does not need to consider the position layout of the pipe. At the same time, the connection method is very convenient and can be used now. Connected, a variety of quick plugs for connecting compressed air, flexible and variable specifications, can be applied to different connection methods; at the same time, the pressure of compressed air can be adjusted according to actual needs. Compressed air can also be used in the following aspects. The compressed air can be used for the mixing cycle. In the process of adhesive production, such as sudden power failure or motor failure, the solid fuel can be connected immediately to prevent the solid glue. Stirring is by introducing compressed air from the bottom of the reactor and using compressed air for emergency agitation. Our factory has emergency cycle of 20 tons of resin, the mixing effect is very good! If the raw materials in the storage tank need irregular circulation, but it is not convenient to install the stirring slurry, you can also install the ordinary ball valve directly on the side or the lower part of the tank or install the straight straight tube from the top of the tank. The pipe material leads directly to the lower part of the storage tank. If it needs to be circulated temporarily, the compressed air is connected, and the valve can be used to realize the circulation of the finished raw materials in the storage tank, which is safe and simple. The above method only needs to consider the position of the compressed air valve and the convenience of the air source in advance.
In the production of compressed air, it is often necessary to empty the remaining material in the periodic pipeline to prevent freezing and cracking of the pipeline in winter. For example, after the water is supplied to the cooling water system in winter, it is necessary to evacuate the pipeline in time. Water, to prevent the pipe from freezing and cracking; after the formaldehyde is collected, the pipe is drained. In the case of long equipment downtime, in order to prevent the glue in the glue pipe from thickening and curing, it needs to be emptied, etc. The start of the installation of a compressed air valve, using compressed air to directly blow the material to the destination, is economical and convenient.
The use of compressed air to clear the dredge pump and the dredge of the pipeline can also be accomplished by using compressed air. The population of the submersible sewage pump often blocks the debris and affects the sewage discharge. If it is necessary to clean up the sundries, it takes time and effort, and the compressed air can be temporarily used for dredging. The effect is also obvious. In the past, if the sewage pump inlet blocked the sundries, the entire waste water must be cleaned before the population can clean up the debris. It takes about 2 hours, and it takes only 23 minutes to complete the use of compressed air. Of course, the compressed air should only be blown to the direction of the pump body. At the same time, after the dredging is completed, the residual gas in the pipeline should be drained in time, otherwise the submersible sewage pump can not work normally to transport sewage.
Accelerated feeding with compressed whole gas In the production of melamine resin, melamine is the main raw material for production. Because of its extremely fine particle size, how to quickly and easily cut the material becomes a difficult problem for production. In order to conveniently and quickly add melamine to the reaction kettle, various manufacturers have thought that the effect of using a vibrating bar feed screw or directly feeding the reactor is not satisfactory. After practice, we put a galvanized steel pipe in the hopper before the addition of melamine to the hopper. The length is close to the position of the melamine dropping port, the compressed air is connected, and then the melamine is added to the hopper. If you need to add melamine to the reactor, you can turn on the compressed air to blow the melamine to force it to be cut off as soon as possible. This method is very economical and practical. It has been proven that 2,8 tons of melamine can be added to the reactor at 515 through a hopper opening having a diameter of 300.
There are many other uses for compressed air. The use of compressed air not only saves manpower and material resources, but also reduces labor intensity, which is widely welcomed by operators.
Concrete pile wire cage welding making machine is a special-purpose welder used to produce the high-strength concrete pile reinforcement cages. Because of the technologies, electric concrete pile steel mould for precast concrete can maintain its stable chemical and physical properties.Having passed relevant tests, the product has been proved to be suitable for the field(s) of Moulds.
