Many people worry that their floor will be damaged when purchasing file racks. When laying, they should lay the floor first or not. If the floor is laid, which way should you choose to lay the track? In fact, this depends on the selected file rack manufacturer. Whether a good file rack manufacturer chooses to tile or slot, it will not affect the floor. In response to these problems, the compact rack manufacturer will give you a detailed explanation of the laying methods of the compact track, and whether the ground will be damaged when laying the track.

Laying method of compact rack

Mobile archive shelving

The laying methods of common file rack tracks are basically divided into two types: above-ground rails and underground rails:

1. Ground track

The above-ground track is not only easy to install, but also less destructive to the ground. The operation method is to lay the track directly on the ground and fix it with the ground with bolts.

2. Underground track

The underground track needs to be cut through the ground for re-grooving, or it needs to be pre-embedded. The installation operation is to lay the track of the dense frame below the ground. The laying method needs to be selected according to the specific conditions of the archives.

The key to the carrying capacity of warehouse racks depends on the type of rack. Different types of shelves have different scope of application and different natural load standards. We have made a detailed summary of the load-bearing standards of different shelves, let’s take a look at it~

The load-bearing standard of different shelves

1. Light shelf

Each layer can carry 100kg-200kg, and the height can be adjusted at will, which is suitable for the storage of light bulk parts. L1500*W500*H2000 (four layers) general specifications.

2. Medium shelf

Each layer can carry 150-250kg, the height can be adjusted at will, and it is easy to install and unload.

3. Heavy duty shelves

Each layer can carry 800kg-4000kg, which is suitable for the storage of various goods. Pallet stacking height and forklift operation make full use of space and are more commonly used shelves. For heavy-duty shelf design, the shelf length is generally less than 3.5 meters, because the longer the shelf, the worse the bearing quality, less than 3.5 meters, which is a more appropriate spacing. Generally speaking, how high is your warehouse, how high can heavy-duty shelves be designed, forklifts are convenient and fast to use, and the storage effect is good.

The plant grow rack is a high-efficiency agricultural system that realizes the annual continuous production of crops through high-precision environmental control in the facility. In a limited space, scientists use computers to precisely control the temperature, humidity, light, carbon dioxide concentration, nutrient solution and other environmental conditions required for plant growth and development to obtain high-quality, high-yield agricultural products. So what are the advantages of growing racks over traditional farming systems?


That is to say, intensive production reflects the overall comprehensive benefits of resources, technology and labor, improves the material output per unit area, and alleviates the contradiction between food supply and demand. The plant growth rack adopts a three-dimensional planting method, compresses the area of ​​the equipment to expand the planting area, and effectively utilizes the indoor space and equipment space through reasonable hole design.

Grow racks


That is to fully tap the potential of agricultural and industrial by-products, light, water and other resources, ease the contradiction between man and land, ease the conflict between grain and cash crops, vegetables, fruits, etc. for land, improve the utilization rate of resources, and improve the utilization rate of artificial auxiliary functions. usage efficiency. Take lettuce as an example, it takes about 40 days to mature under natural conditions, but only about 20 days in a plant factory. At the same time, because of multi-layer cultivation, on the same area of ​​land, the output of plant factories can reach dozens or even hundreds of times that of conventional cultivation.

Calcium hydroxide equipment, also known as calcium hydroxide production line, is mainly used for the production of calcium hydroxide. With the increasing application of calcium hydroxide in industrial production, calcium hydroxide equipment has also been upgraded many times. There has been a qualitative change from performance to product. For the production process of calcium hydroxide equipment, everyone is not very clear, so in response to this problem, calcium hydroxide equipment manufacturers give you the following detailed introduction.



1. Pulverized calcium oxide

During production, the raw material calcium oxide (CaO) needs to be added into the silo, and then added to the jaw crusher evenly through the vibrating feeder, and crushed to a particle size of about 40 mm. The dust generated during the crushing process will be introduced into the pulse dust collector outside the workshop through the dust cover of the crusher through the induced draft fan. It is recommended to clean the calcium oxide powder in the dust collector once a week.

2. Digestive reaction

The crushed calcium oxide is lifted to the digester by the bucket elevator for digestion reaction. Calcium oxide needs to enter the first-level digester for preliminary digestion. When the primary digestion is completed, it will enter the second-level digestion or the third-level digester, so that the calcium oxide can be fully digested and decomposed to generate qualified calcium hydroxide primary products. Can reach 98%.

The feed port of the digester is designed with a screw feed propeller to facilitate material transportation. Most of them adopt a double-shaft stirring structure, which has the functions of stirring, crushing agglomeration and self-cleaning. Its unique paddle and stirring formula can make calcium oxide and water fully and evenly mixed together, the reaction is more complete, and it plays a role in the agglomeration generated during the reaction.

In daily production, during the use of the vibrating screen, a relatively obvious material conveying is suddenly not smooth, followed by the problem that the discharge is biased in a certain direction. To solve this problem, we must first find out the reason for the deviation of the material, and then find out how to solve the problem of the deviation of the vibrating screen. In response to the above problems, the vibrating screen manufacturer gave us a detailed introduction.

The reason for the deviation of the vibrating screen

High frequency dehydration vibrating screen

1. The vibrating screen has a long working time

The vibrating screen has a large workload and a long working life. For a large linear vibrating screen, due to its heavy weight, if coupled with repeated vibration and strong inertia for many years, some parts of the body will be loose, which will lead to vibration. The angle of the motor changes, so the phenomenon of discharge deviation occurs.

2. Uneven feeding

If the vibrating screen is feeding more or less, it is easy to cause unstable screening accuracy, and because of the more or less material, the force deviation of the material is large, and there is a problem that the discharge is biased to one side.

3. Exciter installation problem

The transportation and screening of materials by the vibrating screen is pushed by the vibration exciter to the material with a fixed magnitude of excitation force in a designed fixed direction. Therefore, if the material conveying is not good, it can basically be judged as a vibration exciter. There is a problem with the installation angle. Under normal circumstances, the manufacturer will perform precise installation, testing, and adjustment before the equipment leaves the factory to avoid the deviation of the excitation force direction, so this problem is generally not the cause of the new machine.

Introduction to the fluidization of powder particles

When the gas enters the powder layer from the lower part of the container, if the gas flow rate exceeds a certain value (0.015m/s for cement), the friction between the gas and the powder is equal to the weight of the powder, and the powder no longer depends on the flow. The bed supports, at this point they can move freely and flow from high to low, keeping the upper plane of the powder layer horizontal, similar to liquid properties.

If there are holes in the side wall of the container at this time, the powder can also be ejected from the holes. This is called the fluidization of the powder. The cement truck utilizes the fluidization characteristics of the powder to realize unloading. The function of the fluidized cloth is to make the compressed air form a fine and uniform airflow into the powder layer to fluidize the powder.

Concrete mixer truck is a special truck used to transport concrete for construction. This type of truck is equipped with a cylindrical mixing drum to carry the mixed concrete. The power is transmitted to the hydraulic pump, the hydraulic energy generated by the hydraulic pump is transmitted to the hydraulic motor through the oil pipe, and the hydraulic motor converts the hydraulic energy into kinetic energy and transmits it to the mixing tank through the deceleration and torque increase of the reducer. The handle angle can realize the forward and reverse rotation of the mixing tank and the size of the rotating speed, so as to realize the operations of concrete charging, stirring, stirring and discharging. The concrete mixer truck will always keep the mixing drum rotating during transportation, so do you know why it needs to rotate while walking?

1. Improve the efficiency of use

concrete mixer truck

Concrete mixer trucks involve transportation time, and it takes a certain amount of time for concrete to travel from the manufacturer to the construction site. If the concrete mixer truck walks and turns on the road, the mixing time of the materials can be combined with the time of transportation on the road, which improves the utilization rate of time and improves the work efficiency. Especially in hot summer, the solidification of concrete can be prevented by continuous stirring. After all, for manufacturers and builders, the value of a truck of concrete is still great.

In major mining enterprises, the briquetting machine is an important material forming equipment, and its forming efficiency directly affects the production efficiency of the enterprise. In order to increase production, many enterprises often increase the speed of the briquetting machine. Does the rotation speed really affect the quality of the ball? Does faster revs really increase production? In response to this problem, the briquetting machine manufacturer gave us a detailed introduction.

The principle of briquetting machine forming

The forming principle of the briquetting machine is to extrude the falling powdery material in the ball socket through two rollers with the same shape, the same number and the same position on the surface to remove the air between the material particles and make the particles more compact. compact to form pellets with the same shape and size as the ball socket. The pelletizing rate of this molding method is directly affected by the characteristics of the material, as well as the gap between the rollers and the pressure and rotation speed. When all parameters are appropriate, the quality of the pellets to be guaranteed.

High pressure briquetting machine

The influence of the speed of the briquetting machine on the quality of the balls

As for the quality of the balls only when the parameters of the briquetting machine are appropriate, can the production volume be improved simply by increasing the rotational speed when other parameters are inconvenient? The answer is not necessarily, and whether the speed is too fast or too slow, it has a serious impact on the formation of the ball.

In China, soilless cultivation began in the 1970s, mainly to cultivate soilless seedlings of rice and vegetable crops. At this time, the cultivation method was mainly flat cultivation. With the development of economy and the improvement of people’s living standards, the cultivation form of soilless culture has begun to be used for soilless cultivation of vegetables, flowers, fruits and Chinese medicinal materials.

In recent years, the vertical cultivation mode has been vigorously advocated in the plant planting industry. Among them, vertical cultivation is an important development direction of soilless cultivation, and in vertical cultivation, vertical growing racks are an important tool to realize vertical cultivation. Today’s article is mainly about We introduce what is a vertical growth rack, and the classification of vertical growth racks.

vertical growth racks

1. What is a vertical growing rack?

The form of the growth frame can be divided into trough cultivation, bag cultivation and pot cultivation according to the difference of soilless cultivation troughs. According to the space arrangement of soilless cultivation troughs, it can be further divided into plane cultivation and vertical cultivation.

Soilless cultivation Vertical cultivation is also known as three-dimensional cultivation. The growth of plants in vertical growth racks develops in multiple directions, which can make full use of various cultivation conditions such as time, space and light, exert the production potential of limited ground , and effectively improve land and light, heat and water. The utilization rate of natural resources such as , fertilizer, gas, etc., to make the best use of the land and resources, to establish a good agricultural ecological economic complex, to solve the contradictions such as more people and less land, and competition between food crops and other economic crops, etc. Improving the output rate per unit of land is a form of cultivation and planting that achieves high quality, high yield, high efficiency, energy saving and environmental protection. Compared with flat cultivation, the utilization rate of land by vertical cultivation can be as high as 4 to 8 times, and the management effi ciency of vertical cultivation in soilless cultivation is also much higher than that in flat cultivation, and it is very easy to realize automatic cultivation.
