Most hydraulic manifold manufacturers in China do not produce hydraulic cartridge valves, and some even purchase manifold blocks externally. Recently, a listed company in China (with multiple types of hydraulic equipment) left a message on the website of hydraulic manifold manufacturer AAK: Can you produce 300 hydraulic manifolds within 30 days? I didn't reply as soon as I saw it was from the domestic market. The next day, the other party called directly. I replied to him: Sorry, AAK only focuses on foreign markets, and hung up the phone. Surprisingly, on the third day, the other party came to AAK factory directly. After communication, it was learned that a hydraulic manifold manufacturer in Ningbo recommended AAK to him. It turned out that the hydraulic manifold blocks he purchased from the original hydraulic manifold manufacturer had hidden problems, and more than half of them needed to be re produced. This batch of equipment was for Russian market, and ship date could not be delayed. He also knows that the hydraulic manifold manufacturer AAK is focused on the foreign market, and their equipment is also exported to the foreign market. He hopes that AAK can produce this order. Producing 300 hydraulic manifold blocks in 30 days, in addition to redraw work drawings, according to the conventional production layout, time will definitely not be enough. Moreover, the processing difficulty of this manifold is high, and the oil circuit is complex. There should be less than 3 hydraulic manifold manufacturers in Ningbo China that can handle this order. After 2 hours of communication, the other party said that within 30 days, the hydraulic manifold manufacturer AAK can produce as much as possible. Actually, it's not because AAK is conservative or not, but because AAK's vision is in the international market. Our efficient equipment serves our old customers in the international market. It's not too difficult to produce 300 hydraulic manifold blocks with over 20 days of full load production, as long as there is equipment that can process multiple hydraulic manifold blocks at the same time. Most hydraulic manifold manufacturers process manifold blocks one by one. But hydraulic manifold manufacturer AAK has a CNC from Taiwan that can process 8 manifold blocks simultaneously. Simply put, one equipment of AAK is equivalent to 8 equipment of other hydraulic manifold manufacturers. This video has been briefly filmed before, but the fixture of this equipment has flaws, and AAK is currently undergoing personalized customization and upgrading. The advantages of this CNC are high accuracy, a movement speed of up to 48 meters per minute, and equipped with 24 water jet drills. While cooling the cutting tools, it can also wash away chips and avoid residues. The ability to process 8 manifold blocks at the same time is the main reason why we bought this equipment. With one program debugging, we can complete the same surface processing of 8 hydraulic manifold blocks. Eight hydraulic manifold blocks are placed in the fixture and manually tightened, which poses a potential problem and requires experienced technicians to operate. Most operators are still unable to handle this manual process. Hydraulic manifold manufacturer AAK in Ningbo China, has a high production capacity of 1 day equals to 8 days of peers in the industry.

Product Description Chinese liquid soil stabilizer, rock forming agent, road solidification Rammed earth wall solidification agent rammed earth technology rammed earth wall solidification agent rammed earth wall Adding cement Type A soil stabilizer JUSTSOLID ® technology manual I . Product introduction 1.1 Definition of soil stabilizer Soil stabilizer is a new type of environmental protection curing material, which acts directly on the soil to solidify the soil into a dense, uniform, high strength and durable composite stabilized soil layer. Composite stabilized soil is a semi-rigid material formed by new engineering material soil stabilizer and soil stabilization. Compared with the commonly used inorganic combined stabilized materials, the composite stabilized soil can achieve local materials, and has the characteristics of convenient construction, short construction period, low cost and excellent technical indicators for road use. In a certain range, it can replace the commonly used gravel, crushed stone, reduce the amount of lime and other inorganic binding materials, thus reducing the project cost, saving resources, saving energy, and conducive to ecological environmental protection. This technology is used in the construction and repair of composite stabilized soil subbase and base of new and reconstructed highway engineering, as well as pavement construction, wall construction and repair of different purposes. It has broad application prospects in municipal, transportation, water conservancy, foundation treatment and other projects. 1.2 Classification of soil stabilizer In CJJ/T286-2018 Technical Standard for the Application of Soil Solidifying Agent, the soil solidification agent is divided into Class A soil solidification agent and Class B soil solidification agent. Class A soil stabilizer: a powder or liquid additive that can improve the engineering performance of the foundation soil by physical or chemical reaction with cement (or lime and other cementitious materials), soil, water and air after being added into the soil. Class B soil stabilizer: after being added into the soil, it is a soil stabilizer that can be used alone through the physical or chemical reaction with soil, water and air, not mixed with cement (or lime and other cementitious materials), and a powder additive that can improve the engineering performance of the foundation soil. II. Physical and chemical properties Form: liquid or granular powder Solubility: soluble in water Type: ionic polymer type biological enzyme type Safety: ecological and environmental protection III.　Action mechanism The working principle of composite stabilized soil is to make the surface current of soil micelle reduce energy and fix a large amount of free water in the soil in the form of crystal water. The engineering properties of the soil are changed by a series of physical and chemical reactions after the soil stabilizer is mixed with the soil. The particles tend to agglomerate, the electrolyte concentration increases, and the volume expands to further fill the soil pores; Under the action of compaction, the whole structure is formed to make the solidified soil easy to be compacted and stable, reach the compactness that cannot be achieved by conventional methods, and improve its strength, compactness, modulus of resilience, deflection value, CBR, shear strength and other properties, so as to meet the requirements of road technical indicators. IV.Adaptability and scope of use Soil stabilizer can be applied to a variety of soil properties, such as clay, silt and sand; Mineral powder, slag, construction waste, etc. According to different soil properties, different curing schemes are formulated by adjusting the material ratio. 1. Subgrade construction The subbase of the expressway is hardened, and the base and subbase of the first class road and below are hardened. Hardening of base course and surface course of simple road or temporary road. Cement soil, soft soil and soft foundation solidification. 2. Site hardening Hardening treatment of parking lot, road, stockyard, storage yard, drilling well pad, production and processing yard, etc. 3. Rammed earth wall Vegetable, flower and breeding greenhouse; Construction or repair of ancient building walls; Earth wall of folk houses, etc. 4. Making unburned bricks After fully mixing the clay with the soil curing agent, it is supplemented with other hydraulic materials and directly pressed by the brick press. V. Construction plan 5.1 Basic Requirements ① Cementitious material: cement. It shall comply with the current national standard General Portland Cement (GB175). Cement of the same grade, brand, variety and delivery shall not be mixed. Cement grade 425 and above. The initial setting period is required to be more than 3 hours, and the final setting period is about 6 hours, not more than 10 hours. ②Water quality requirements: the water shall be non-polluting water (potable water for livestock). It conforms to the current industrial standard Standard for Concrete Water JGJ 63. ③ Construction thickness: the compaction thickness of each layer should be 15-20 cm (cm), and the total compaction thickness should be determined according to the construction requirements. ④ Addition of cementitious materials: the amount of cementitious materials generally accounts for 3% - 6% of the total soil amount. The details shall be determined according to the construction requirements and process. ⑤ Amount of soil stabilizer: about 0.5 kg per cubic meter of compacted earth; It is about 0.03% (three thousandths) of the mixture by weight. Curing agent for sealing layer: after curing, spray on the surface of solidified soil, dilute with water about 20 times, and spray the sealing layer. ⑥ Moisture determination method: Liquefied Road Soil Stabilizer Rammed Earth Wall Solidification Agent 0 Liquefied Road Soil Stabilizer Rammed Earth Wall Solidification Agent 1 Figure1 Soil moisture meter Figure2 Traditional simple method Use a soil moisture meter or traditional simple method: grab a handful of soil, put it in your hand and hold it tightly, and the soil mass will be formed without scattering; One meter from the ground, let the soil mass fall freely, and the soil mass spread evenly (fall to the ground and blossom), indicating that the moisture content is about 15%. ⑦ Material consumption: For example, the area of the soil to be solidified is calculated as 5 square meters, the thickness is 20 cm, and the total volume is 1 cubic meter after compaction. The density after compaction is calculated as 2 tons/cubic meter, and the total volume is 2 tons. *Earthwork=area * thickness=5 square meters * 0.2 meters=1 cubic meter * Total soil volume=earthwork * compaction density=1 * 2=2 tons; *Amount of cementitious material (cement)=total soil quantity * 10%=2 * 10%=0.2 tons； *Amount of soil stabilizer=total earthwork * amount of soil stabilizer=1 m3 * 0.5 kg/m3=0.5 kg; *Water consumption of diluting and curing agent=(optimum moisture content * total solid content) - (initial soil moisture content * total soil content) =18% * (soil volume+cement+diluted water) - 12% * total soil volume Note: In the formula, the initial water content of soil is calculated as 12%, and the optimum water content is calculated as 18%; The specific construction shall be subject to the actual water content.

Martin, a purchaser of American company PowerTeam, sent an email last week saying that he saw on the Internet that AAK was a hydraulic valve supplier of some European hydraulic pump companies. He wanted to know whether the quality of AAK could match the quality of the hydraulic valve produced in the United States he was currently using. I directly answered that the quality of hydraulic valves in the United States should also be in different levels, you can have a small try and compare them with your hydraulic valves purchased in the United States. Martin frankly told about his current purchasing status. He needed to re- purchase a batch of hydraulic sequence valves for hydraulic pumps. After placing an order with the original manufacturer in the United States, the manufacturer told him that there were not enough labor for mass production at this moment. He had to wait for 3 months at least. The boss was not satisfied with his purchasing arrangement and asked him to find a new supplier of hydraulic sequence valve and complete production within 2 months. Martin is a little embarrassed because this hydraulic sequence valve has particularly high requirements for various accuracy. In the early stage of development 3 years ago, he contacted more than 20 hydraulic valve manufacturers, compared and tested the hydraulic sequence valves from them, and only the samples from the local hydraulic valve manufacturer in the United States met the requirements. Martin saw the information of AAK to found that it was actually the supplier of hydraulic pumps in Europe. After browsing AAK website (www.aakindustry.com), he felt that AAK hydraulic valve might become his supplier. According to the drawings and working conditions of his hydraulic sequence valve, we found that it does have high requirements for the accuracy of the hydraulic sequence valve. I told Martin that we need 15 days to make and test samples. After the samples of the hydraulic sequence valve pass the test, we will discuss the order at that time. 10 days after the hydraulic sequence valve sample was sent, Martin emailed AAK that the hydraulic sequence valve fully met the production requirements of the existing hydraulic pump. At the same time, the engineers of PowerTeam also applauded every detail of AAK hydraulic sequence valve sample, which was no worse than that of the American company. In particular, some core parameters, such as the matching surface roughness of AAK hydraulic sequence valve spool and valve hole, can reach Ra value of 0.1 ~ 0.2μm. The surface roughness Ra value of the outer circle of the valve spool is 0.1μm. The Ra value of the inner circular surface of the valve hole is 0.2μm. Some parameters are even higher than those of his original American manufacturer, including 100% burr removal. Martin was surprised how AAK hydraulic sequence valve achieve these? AAK hydraulic valve has two absolute advantages and has already surpassed its domestic counterparts. It is uncertain whether it has surpassed its American counterparts. 1. AAK has a high-precision CNC machining center imported from Switzerland and independent fixtures upgraded and refitted by itself, eliminating human errors. 2.The independent professional R & D team cooperates with the unique R & D technology to realize the personalized customization demand of hydraulic valve accuracy, which can not be achieved by 95% of domestic peers. When Martin got the quotation of AAK hydraulic sequence valve, it was 23% cheaper than that produced locally in the United States, but the quality was no worse than that produced locally. AAK needed a lead time of 35 days for production, and the whole time was also in line with Martin's re-purchasing time schedule. After finalizing the whole order, Martin reported to the boss. The boss was very happy that AAK hydraulic sequence valve benchmarked the American quality, and also saved the purchasing cost. Martin told me that his boss asked him to send samples of previously purchased hydraulic valves to AAK for quotation. AAK hydraulic sequence valve keeps pace with American manufacturers. Not only the hydraulic sequence valve, our quality of hydraulic flow control valve also convinced a Germany customer.
