France hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder
(France synchronous hydraulic cylinder,produced by Hengyu Group）
synchronous hydraulic cylinder are widely used in France，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed synchronous hydraulic cylinder for customers from France.
The role of the synchronous hydraulic cylinder in the mold industry: the synchronous hydraulic cylinder has a variety of uses in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the synchronous hydraulic cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product to decide, sometimes customers require the use of hot runner, the price is more expensive, but there are many benefits, you can save raw materials, shorten the molding cycle The synchronous hydraulic cylinder has an irreplaceable role in the heavy industry production process: it is mainly used in places that need to support heavy objects for a long time, and it can still support heavy objects when the oil pressure is removed, and it is safe and reliable. Can be used underwater, single action, load reversion, nut self-locking to make the load safer, especially in large projects, is easy to operate control and self-locking jack, designed with a safety pressure retaining device, built-in pressure relief valve to prevent overload, to protect the self-locking jack to facilitate safe operation. The connection of the device is connected by high pressure hose and threaded joint, which has the advantages of fast use and overcoming the shortcomings of fast traditional joint oil leakage. It is mainly used for equipment installation and toppling operation in various industries such as electric power, construction, machinery manufacturing, mining, railway bridge, shipbuilding and so on.
In order to ensure the service life of the synchronous hydraulic cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the synchronous hydraulic cylinder, causing damage to the seal and causing leakage in the synchronous hydraulic cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.
synchronous hydraulic cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the synchronous hydraulic cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.
The synchronous hydraulic cylinder should be used correctly and maintained regularly. The synchronous hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the synchronous hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.
How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.
