With the rapid development of industry, nitrogen generators have been widely used in chemical, electronics, metallurgy, food, machinery and other fields. Among them, PSA nitrogen generators using pressure swing adsorption technology have become the mainstream nitrogen generation method. What are the components?

• 

• 

1. Compressed air purification system

Carbon molecular sieve is a key material that determines the production capacity of nitrogen generators. Since compressed air provided by air compressors usually contains traces of oil, water, and dust particles, these impurities, especially oil molecules, will reduce the adsorption capacity of carbon molecular sieve, so compressed air is Before entering the oxygen-nitrogen separation system, oil and water and dust must be removed. First, the air is compressed to 0.75-1.0MPa by the compressor and enters the air purification system. The pipeline filter removes most of the water, oil and dust impurities, and then the refrigerated dryer cools and removes the water so that the pressure dew point reaches 2℃-10℃. It is filtered through the fine filter, super fine filter, and activated carbon degreasing device again to obtain clean compressed air with a pressure of 0.75-1.0MPa, a pressure dew point of 2℃-10℃, and an oil content of ≤0.01PPm. The compressed air purification system consists of a pipeline filter, a freeze dryer, a fine filter, a super fine filter, an activated carbon degreasing device, an automatic drain valve, a ball valve, etc. Click here you can check our nitrogen generator for sale.

3. Oxygen and nitrogen separation system

The oxygen-nitrogen separation system is the core part of air separation. Its main body is two adsorption towers filled with carbon molecular sieves. When clean compressed air enters an adsorption tower, O2, CO2 and trace H2O are adsorbed by carbon molecular sieves, and nitrogen is output from the outlet. Become product nitrogen. When one tower is adsorbing nitrogen production, the other tower discharges the O2, CO2 and H2O adsorbed in the molecular sieve from the micropores by decompressing, so as to realize the regeneration and desorption of the molecular sieve. The two towers alternately perform adsorption and regeneration, and continuously output nitrogen. The oxygen-nitrogen separation system consists of an adsorption tower, carbon molecular sieve, pneumatic valve, muffler, throttle valve, compression cylinder, pressure gauge, etc. packed in the tower.

The use of mini roller compactor for road construction is relatively a better choice. According to different projects, different paving thicknesses, different road types, and different types of materials to be pressed, the type of mini roller compactor selected is also available. The difference. The choice of mini road roller is related to the efficiency of highway construction and the quality of the project, so choosing the right road roller machine is very important for construction.

• 

• 

1. Choose according to engineering quality requirements:

If you want to obtain a uniform compaction density, a tire-type road roller machine can be used. The tire-type road roller machine does not destroy the original viscosity of the soil during rolling, and has good bonding performance between the layers of soil. The front wheel can swing, so the compaction is more uniform and there will be no false compaction.

If you want to make the road surface compact and smooth, you can choose a full-drive roller compactor. In areas where the compaction capacity of the roller compactor is not high, a flexible roller with lower line pressure can be used. To achieve the compaction effect as soon as possible, a large-tonnage road roller machine can be used to shorten the construction period.

• 

• 

2. Choose according to layer thickness:

When rolling an asphalt concrete pavement, the weight, amplitude and vibration frequency of the road roller machine should be selected according to the paving thickness of the mixture. Generally, on thin pavements with a ply thickness of less than 60mm, a small 2-6t vibratory roller with an amplitude of 0.35~0.60mm is used to avoid piles, waves, and damage to aggregates. At the same time, in order to prevent the asphalt mixture from being too cold, it should be rolled immediately after paving. For thick plies with a thickness greater than 100mm, a large and medium-sized vibratory roller with a high amplitude (up to 1.0mm) and 6~10t should be used.

3. Choose a small roller according to the type (grade) of the road:

For the first and second national arterial roads and special roads for automobiles, a large vibratory roller with a high compaction capacity of 6~10t should be used; for roads below the third level, or when compaction operations are not frequent, a 2t or so should be equipped Flexible vibration road roller. For cement concrete pavements, tire-driven tandem vibratory rollers can be used; for asphalt concrete pavements, full-drive vibratory rollers should be used;

• 

4. Choose according to the type of material to be pressed:

For rock fill compaction, a large-tonnage road roller machine should be used to displace large blocks; for clay compaction, it is recommended to use bump tamping road roller; for mixture compaction, choose vibratory road roller in order to mix the large and small particles evenly.

7. Thicken steel to ensure safety: brand-name control electrical system, equipped with integrated working buttons, one-key start, easy operation;

• 

• 

8. Fog cannon dust suppression has an automatic drainage function. When the equipment stops working, the water in the pipeline must be automatically drained.

9. The mist cannons machine has the function of phase sequence protection and automatic shutdown protection. When the current is too large, the phase sequence is wrong, and the water pressure is too low, the equipment will automatically stop running.

10. Equipment operating noise is required to be less than 90 decibels at 10m, and meet environmental noise standards.

For many factories that use metal or other machinery and equipment, it is necessary to have useful cleaning equipment, because this frequently operated machinery will rust or leave a lot of substances after long-term use. There are two types of cleaning equipment that are often used: shot blasting machine and sandblasting machine. Now, I want to recommend to everyone the portable sandblasting machine.

The portable sandblasting machine is different from the shot blasting machine in that it is powered by compressed air, but it also achieves the purpose of cleaning through high-speed operation, and it also has the function of cleaning the surface of the object. In addition, the automatic sandblasting machine can also change the internal structure of the object, eliminating the stress on the object, and extend its life while making the object durable.

• 

• 

The portable sandblasting machine is compared with the general automatic sandblasting machine, but it simplifies the structure of the sand blasting machine and is simple and convenient to use. Even ordinary workers can learn to operate in a short time, thus avoiding unskilled operations. There is a problem with operational safety hazards. The second is its high precision. This “precision” is not only reflected in its ability to operate accurately and stably, ensuring stable quality, but also in its ability to remove some stains that are difficult to remove in certain parts without worrying about damage. To the surface of the object.

• 

• 

The sand blasting machine is a machine that uses compressed air as power to form a high-speed jet beam to spray sand to the surface of the workpiece to be processed at a high speed so that the mechanical properties of the surface of the workpiece are changed. Due to the impact and cutting action of abrasives on the surface of the workpiece, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved, thus improving the fatigue resistance of the workpiece, and adding it and coating The adhesion between the coatings prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating. It removes impurities, variegated colors and oxide layers on the surface. At the same time, the surface of the medium is roughened, so that the residual stress on the surface of the substrate can be eliminated and Improve the surface hardness of the substrate. According to the characteristics of mobile sandblasting equipment, the sandblasting machine is suitable for cleaning the rough surface of forged castings, stamping parts and machined parts. It is used for spraying, pretreatment before electroplating, and strengthening the surface of polished parts. The portable sandblasting machine is especially suitable for medium and Single or mass production of small parts.

A concrete pump, also known as a concrete pump, is a machine that uses pressure to continuously transport concrete along a pipeline. It consists of a pump body and a delivery pipe. It is mainly used in building, bridge, and tunnel construction. Concrete pumps are divided into gate valve concrete pumps and S valve concrete pumps. In addition, there is a pump body mounted on the chassis of the car, equipped with a retractable or flexural placing boom to form a pump truck.

• 

• 

At present, the small concrete pump has been widely used in major construction sites. The use of pumping in accordance with the operating rules can not only speed up the construction efficiency but also prolong the service life of the small concrete pump. Only such a machine can take on a higher level. Engineering.

Mobile mini concrete pump construction is flexible, economical, and efficient. The conditions of the construction site are often more complicated, so many construction parties hope that the pump can maintain the construction characteristics of flexibility and high efficiency. The company’s portable concrete pump adopts stepless variable adjustment technology, which can realize the simultaneous change of concrete working conditions and displacement, and effectively change the suction performance of the pumping system.

Note for mobile concrete pump truck operation:

It has an inseparable relationship with the performance of concrete. At the same time, pay attention to the details of the operating procedures during the operation, find and troubleshoot in time, so as to improve the work efficiency of the concrete boom pump. There are two methods for pipe cleaning: water washing and air washing. Whether it is water washing or air washing, the valve box and hopper must be cleaned. When washing, put the cylindrical cement bag soaked in water and the cleaning ball into the cleaned cone pipe successively, connect the cone pipe and pipeline, close the discharge door, and then fill the hopper with water (must keep Continuous water supply). Pump water until the cleaning ball emerges from the front end of the delivery pipe. Air washing is compressed air washing, which is to plug the water-soaked cleaning ball into the air-washing joint first, then connect the first straight pipe connected with the reducing pipe, and attach a safety cover to the end of the pipe. The orifice should face down. Control the pressure of compressed air not to exceed 0.8MPa, and the air valve should be opened slowly, and the air valve can only be opened when the concrete can flow out smoothly.

1. Concrete pouring elements The selection of concrete pump trucks should be comprehensively considered based on the concrete engineering objects, characteristics, and required large conveying distances, concrete construction plans, concrete pump forms, and specific conditions.

2. Building type and structure The performance of concrete pump truck varies randomly. When selecting small concrete pump, in addition to considering the amount of concrete poured, the type and structure of the building, construction technical requirements, site conditions and environment should also be considered. Generally, the main performance parameters of the concrete pump truck selected should be in line with the construction requirements or slightly larger. If the capacity is too large, the utilization rate will be low, and if it is too small, it will not only fail to meet the requirements, but will also accelerate the loss of the concrete pump truck.

• 

• 

3. The mobile concrete pump with good construction adaptability is flexible, and the higher the boom height, the larger the pouring height and the spreading radius, and the stronger the construction adaptability. In the construction, the high-boom concrete pump truck should be used as much as possible. The concrete pump truck with a boom length of 28~36m is a large-scale and wide-ranging product on the market, accounting for about 75%. The concrete pump truck with a long boom will become the main model in construction. In addition, there are mobile concrete pumps that are subject to the carrying capacity of the car chassis, and the cost of the boom increases greatly when the boom height exceeds 42m, and is affected by the construction site space, so it is generally seldom used.

• 

• 

4. The number of concrete pump trucks used in the construction business can be calculated based on the concrete pouring volume, the actual delivery volume of a single machine and the construction operation time.

5. Product configuration the product performance of portable concrete pump should stick to a high starting point in the selection. If a high-value concrete pump truck is selected, the standard requirements for its products also need to be improved. The quality of the main components of the product, from the internal quality to the appearance quality, must be adapted to the high value of the vehicle.

6. The portable concrete pump of the power system adopts full hydraulic technology, so it is necessary to consider whether all hydraulic technologies are available and what is the quality of hydraulic vision. Because its power comes from the engine, in addition to considering the performance and quality of the engine, the performance, carrying capacity and quality of the car chassis must also be considered.

• 

7. The operation control system on the mini concrete pump operating system is equipped with manual, wired and wireless space-time methods. It is convenient and flexible to control by the county. The wireless remote control can be operated remotely. Once the circuit fails, manual operation can be used.

8. After-sales service mini concrete pump due to its special functions, mechanical properties, manufacturer’s after-sales service and spare parts supply should be requested. Otherwise, if an accident occurs, it will not only affect the construction progress, but also the imaginable consequences of the production department.

For broken pile heads, when pouring cast-in-place piles, the elevation of the pile top should be 0.5~1.0m higher than the design elevation of the pile top to ensure the concrete strength of the pile head, but the part of the pile head higher than the design elevation of the pile top must be constructed in the subsequent process The work of removing and removing this part of the pile head concrete is called “broken pile head”. The existing tools for the broken pile head are mainly divided into manual and mechanical. The mechanical name of the broken pile head is pile breaker, pile cutting machine, etc., and the speed is many times faster than that of manual work. Pile breaker is a new type of pile breaking operation equipment, which uses hydraulic principles to controllably split objects. Especially in places where there are strict restrictions on dust, flying debris, vibration, noise, and exhaust gas emissions, concrete pile breaker machines have special advantages that they cannot replace. The concrete pile cutter is suitable for cutting round and square pile heads of pile foundation projects such as high-speed railway bridges, industrial and agricultural constructions, etc. Through the remote control of construction machinery, the pile head can be safely cut off. The risk of personal injury caused by manual construction can be avoided, and the efficiency is dozens of times that of manual construction.
