The plate rolling machine is designed to roll the flat plate into a circular arc and cylindrical shape, which is widely used in the container manufacturing industry. It is indispensable equipment for these companies.
Why does the rolling machine need to be sealed?
What is forbidden to workers when operating a rolling machine?
What is a hydraulic rolling machine?
The reliability and service life of the seals in the hydraulic system of sheet metal bending machine are important indicators to measure the quality of the hydraulic system.
In addition to gap seals, seals are used to keep the gap between two adjacent coupling surfaces below the minimum gap through which the liquid to be sealed can pass. The seals in the hydraulic system of sheet metal bending machine are usually contact seals. There are two types of self-sealing compression seals and self-sealing self-clamping seals, also known as lip seals. However, the factors influencing the performance of different seals in the hydraulic system of the sheet metal rolling machine are different, just as with the three-roller roller. In fact, the seal of the hood is still influenced by temperature, pressure and the existing medium.
During the measurement of the roundness of dimensions, the operator of the rolling machine is forbidden to stand on the rolled cylinder, and it is forbidden to stand on the workpiece to be machined. For some difficult-to-process workpieces, such as thicker or larger diameters, high hardness or strength of raw materials, etc., this should be done by a small number of operations simultaneously to achieve the desired effect. For some workpieces with smaller diameters, they should be rolled in the middle of the rollers for operation.
The main features of hydraulic plate rolling machine: the upper roller of the machine can be lifted vertically, and the hydraulic transmission of vertical lifting is achieved by the action of the hydraulic oil in the hydraulic cylinder on the piston rod; The torque is provided, and there are tensioners under the lower roller that can be adjusted. The upper roller has the shape of a drum, which improves the straightness of the product and is suitable for tanks with various cross-sectional shapes with ultra-long specifications.
Hydraulic rolling machines can roll metal plates into circles, arcs and conical workpieces within a certain range. The two lower rollers of this model are active rollers and the upper rollers driven rollers. It is widely used in shipbuilding, boiler, aerospace, hydropower, chemical, metal structure and mechanical engineering industries.
The hydraulic rolling machine is suitable for bending metal plates. It can roll circular, arc and conical workpieces within a certain range and has the function of pre-bending the end of the plate. The two lower roles of this model are active roles. Horizontal movement, the upper roller is a driven roller and can move up and down. There are mechanical and hydraulic movements. The driveshafts are connected by cardan couplings.
To meet these growing demands, WINCOO ENGINEERING CO., LTD has various rolling machines, all of which are more effective, reliable and consistent.

Do you know the tank hydraulic jacking system?Understand it?Do you know how it jacked up the tank?And do you know how much weight it can lift? Although hydraulic jacking system have been widely used in the construction of large tanks, many people still know little about them. Today I will give you a good introduction to the hydraulic jacking system from the following aspects.
●What is the hydraulic jacking system?
●How does the hydraulic jacking system lift the tank?
●How much weight can the hydraulic jacking system lift?
Hydraulic jacking system is an important machine for tank construction. The equipment is mainly used for inverted construction of vertical cylindrical steel tank (hydraulic lifting method) in petrochemical industry, inverted construction of steel liner in power plant chimney and inverted construction of vertical cylindrical low temperature tank.
At present, we have three types of hydraulic jacking system in WINCOO Engineering Co., LTD. They are the following three: Advanced hydraulic jacking system, Simple unfixing Holding -latch hydraulic Jacking system and Simple chain type hydraulic jacking system.
Hydraulic jacking system (package unit) is evenly distributed around tank inner wall. Tank top and upper (the first layer) wall plates are lifted first and then install and weld wall plates of tank body. Self locking hydraulic jacking system and hydraulic hoist composing of lifting frame and lifting rod are adopted. When oil enters hydraulic jacking system, upper clamp fastens and lifts lifting rod and expansion ring and mobilize tank (including tank top) to ascend upward. When oil returns to jack, upper clamp returns with piston and lower clamp automatically fastens lifting rod without gliding. The jack repeats the movement and make lifting rod ascend with tank to designated height (spare height for next layer of plate). After butt weld of next layer of wall plates, open upper and lower loosening device and loosen upper and lower clamp to make lifting rod and expansion ring descend to lower expanded and welded rib plate of the next layer of wall plates and then lift. Repeat the process and ascend welded tan till the last layer of wall plates are installed and welded. The installation of the whole storage tank is completed.
1.The number of hydraulic cylinders used for the same size tank is different according to the actual use and weight of the tank.
2.Regardless of tank size, hydraulic cylinder installation must be evenly distributed.
3.Construction of different tanks and selection of YT series hydraulic lifting equipment number and calculation of lifting equipment load rate specification: lifting equipment load rate must be less than 80%.
For example, for a storage tank with a volume of 50,00m3 and a diameter of 60m, the maximum weight of the lifting body of the tank is 536T (excluding the weight of the bottom plate of the tank), 40 hydraulic cylinders of YT25-2700 are selected, and the output force of each hydraulic cylinder is 250KN, so the total output force of the lifting device is 25O×40=10000KN.The load rate of the lifting equipment is 536x9.8÷10000×100%≈52.53%, which meets the requirement of less than 70%.
The above is our brief introduction to the hydraulic jacking system. If you have any questions, you are welcome to browse other relevant articles and products on our website. I hope the above content will be helpful to you.
Pipe spool fabrication line refers to the manufacturing (cutting, chamfering, welding) of metal pipes and elbows to manufacture pipelines or pipeline structures, which are commonly used in the oil and gas industry and offshore industries. The pipe spool fabrication line actually prepares all the tube ends from the manufacturing tube to the tube and from the tube to the elbow. Next, describe in detail what is the pipe spool fabrication line?
