The same lift lifting weight 200 kg lighter than similar products 7500 working cycles without exception 250bar (1kg/1cm3=1bar) 10,000 working cycles under normal pressure The average lifting time is 20 seconds faster than similar products ...... Of the domestic fuel tanks, only the Alpha hydraulic system has done it all. It seems unbelievable, but Havoi Machinery (Yangzhou) Co., Ltd. (hereafter referred to as Havoi Machinery), which is dedicated to delivering value to users and the ultimate in products, is already in unparalleled leadership in the solution of hydraulic systems for dump trucks. status. Reducing bore diameter for ultimate lightweight Undoubtedly, the lightweighting of dump trucks has become the mainstream of the industry, but it seems difficult to make lighter articles on hydraulic systems with an average total weight of less than 750 kilograms. In the range of less than 750 kilograms, Hyva Machinery has successfully reduced the weight of the hydraulic system by 200 kilograms and introduced a lightweight Alpha hydraulic system. How did Hayward Mechanical do it? For this reason, the China Truck Network reporter interviewed Mr. Song Zhixin, the product manager of Hayward Machinery. He told reporters that in order to achieve this, from the hydraulic cylinder, there are only two ways, either to reduce the wall thickness, or to reduce the bore, but the former This method greatly reduced the strength of the cylinder, which could easily lead to deformation of the cylinder and was too dangerous. Therefore, the Alpha hydraulic system chose a second solution that reduced the bore diameter and kept the cylinder wall thickness constant. In this way, the Alpha hydraulic system was in the cylinder. The weight of the tube is about 50 kg lighter than similar products. The reduction in bore size will inevitably lead to a reduction in the use of hydraulic oil. The small bore design of the Alpha hydraulic system reduces the use of hydraulic oil by 16%, which in turn reduces the weight of the entire hydraulic system by around 60 kilograms. In this way, the Afar Hydraulic System uses 100 kg of weight for the entire system in terms of cylinder tube and hydraulic oil usage, plus the lightweight design of other components in the hydraulic system, and other domestic hydraulic pressures. Compared to the system, Hayward reduced the weight of the entire hydraulic system by 200 kg. Reducing the bore size and pursuing the ultimate in lightweighting have made the Alpha hydraulic system highly demanding on the material of the cylinder barrel, but this is not a problem in the internationalized Heywood Group. The key components of the new Alpha hydraulic system introduced by Hayward Group are made of materials imported from Europe to ensure the strength of the hydraulic system under the premise of reduced bore diameter and increased system pressure. The reliability of the entire hydraulic system is also higher than similar products. Raise the lift speed for users For dump truck users with short-distance transportation such as city dregs and mine transport, the lifting speed of the dump truck means efficiency. Because the faster the lifting speed is, the more time it takes to transport it, the more it can be shipped in a single day, and that means money. In terms of lifting speed, the performance of the new Alpha hydraulic system at Hayward is commendable. Depending on the DWT, the average lifting time of the tipper is between 50 and 70 seconds, while the alpha hydraulic system's lifting time is between 27 and 48 seconds, which is at least 20 seconds faster than the domestic hydraulic system. How did Hayward achieve this? The original Alpha hydraulic system increased the working pressure of the system while reducing the bore diameter and strengthening the material strength of the system. In this way, the Alpha hydraulic system became the "quick gunner" in the hydraulic system products. The significance of rapid lifting is obvious. Just as the user Wu Dewen from Nanchang said: "The speed of the car's rise has risen, and it will take less time to complete the operation, which has greatly saved fuel consumption during the lift; Sooner, according to my current average of 7 minutes per day, I would have to transport 3 more people than others in the day, and calculate a $20 a day for a car that costs about $700 more. There are 80 vehicle dump trucks, and this benefit is considerable. HT hydraulic lift valve ensures system safety The lightweight design and the pursuit of a fast Alpha hydraulic system is a huge challenge for the safety performance of the entire hydraulic system due to reduced bore diameter and increased system pressure. In addition to the use of excellent materials, the design of the Alpha hydraulic system HT hydraulic lift valve Ensure the security of the system. The Alpha hydraulic system's lift valve design is different from that of similar hydraulic products. First, its mounting position is selected at the bottom of the cylinder, which saves the high pressure tubing from the hydraulic valve to the hydraulic cylinder, avoiding the burst of the tubing; and second, Alpha hydraulic system hydraulic valve can balance the pressure of the entire system to avoid the system over the rated working pressure; Finally, the system's built-in explosion-proof valve, even if other high-pressure fuel pipe burst, the entire hydraulic system can also be locked in any working state in the stop position, Ensure that there are no security incidents in emergencies. In addition to hydraulic valves, the Alpha hydraulic system's tank design also protects the hydraulic system, saving users unnecessary expenses. The Alpha hydraulic system adopts a low oil level design to optimize the position of the air filter element on the fuel tank to ensure that the hydraulic system does not spray oil outward when returning oil. The hydraulic oil tank is also fixed differently from the bolting connection of the domestic hydraulic system fuel tank. It is installed on the fuel tank bracket to greatly reduce the stress concentration caused by jolting of the driving process. The fuel tank is not easy to loosen and fall off. It is installed once and permanently stable. The fastest and lightest Alpha hydraulic system also provides insurance for the safety of the dump truck. In the off-road unloading site, the Alpha hydraulic system's quick-return operation mode reduces the time for the center of gravity of the dump truck and eliminates the dump truck. Due to unstable center of gravity during the unloading process. "As long as the customer is installed according to the standard, the multiple insurance of the Alpha hydraulic system can guarantee absolutely no safety accident." Song Zhixin is very confident in the safety performance of Alpha Hydraulics. Design reflects energy saving and environmental protection The Alpha hydraulic system far exceeding the performance of similar products can also be regarded as a model in the industry in appearance design. Song Zhixin told reporters: "Haiwo mechanical hydraulic system design has long been a model in the industry, causing the industry to imitate. New product Alpha hydraulic The appearance design of the system goes further, demonstrating the characteristics of lighter, faster and safer products while fully demonstrating the concept of energy saving and environmental protection. To prevent other companies from taking a stand, Alpha Hydraulic Systems has applied for a patent for its exterior design." Song Zhixin told reporters that the unique shape of Alpha's hydraulic system was created by the international product design team of Hyva Group. Its appearance design was first shown to people as it was fast, and specifically it was shown through the dust cap on the oblique design of the cylinder. However, the hydraulic system is not fast enough. To lift a heavy cargo box, the hydraulic system must be strong. Although the Alpha hydraulic system has a smaller bore than its counterpart, it does not have any sense of thinness in the visual sense. This is mainly demonstrated by the convex-concave film design on the bottom of the cylinder and on the hydraulic tank. In addition, the Alpha hydraulic system uses a black main color to embellish the yellow color of the product, which is full of power. Energy conservation and environmental protection are the consensus of the present society. The appearance of the Alpha hydraulic system fully demonstrates this. The Alpha hydraulic system has a smaller bore and uses less material. On average, every 10 cylinders can save 2 tons of steel for society. The Alpha hydraulic system's multi-level oil tank design (an oil tank can be adapted to multiple cylinders) reduces the material consumption and also reduces the waste caused by the repeated design process. In addition, the lightweight design of the Alpha hydraulic system allows the hydraulic system to reduce the amount of hydraulic oil, each hydraulic system working oil than the same type of products to reduce 17%, while embodying energy saving and environmental protection, but also for the user to save costs. Bring proven products to market Instead of letting customers use the "white mouse" to bring proven products to market, Havoi Machinery conducts a series of tests on the products before launching the product. The rig test of the Haiwo Group R&D engineers showed that the Alpha hydraulic system has a normal working cycle of 7500 cycles, and the parts are normal through 25000-100000 working cycles. Under the pressure test, the Alpha hydraulic system is under 220 bar pressure conditions. Only 10,000 cylinders started to deform, and the laboratory data of similar products not only failed 7500 cycles, but also deformed 10,000 times at 160 bar pressure. The test data in the laboratory may be too ideal. For this reason, the Alpha hydraulic system has also undergone many road tests before being listed. In the 7-month road test, Haworth Machinery Co., Ltd. took out 40 sets of different types of system products, which were put into Hebei, Nanjing, Chongqing, and other places for field tests, under different operating conditions and different temperatures (-20 degrees to 40 degrees below zero). Under the circumstances, 40 systems that were fully involved in the testing of the Alpha hydraulic system have stood the test. Li Baowei, a user in Hebei who participated in the road test, frankly stated after comparing Alpha's hydraulic system with similar products: "Using this new system, 200 kg per vehicle will be transported each time, and 200 kg will be transported each time. Think about 10 vehicles for half a year. The extra cargo is amazing, but I estimate that the hydraulic system can reduce the weight of 200 kilograms.The estimate is also the limit, and it is difficult to exceed. What I can not think of is that this hydraulic system not only reduces its own weight, but also accelerates 1-2 Times, the lifting process is also very smooth." The face of the reporter asked about the quality of products, "Haiwo quality is really good, the performance is also stable domestic cylinders are imitating Hayward, I used Havo mechanical products before, 6 years, the screws are not bad, this set Of course, there will be no problem with new products," said Lao Li. Products are carefully designed and users have confidence in the product. The Hayward Alpha hydraulic system uses products to speak, thinks of users, creates value for users, and successfully creates a new chapter in the field of hydraulic cylinders for dump trucks.
