Egypt hydraulic cylinder,press hydraulic cylinder manufacturer,press hydraulic cylinder(Egypt press hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
press hydraulic cylinder are widely used in Egypt,because of long service life,smooth movement,high work efficiency.So our company has designed press hydraulic cylinder for customers from Egypt.
In order to ensure the service life of the press hydraulic cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.
When the press hydraulic cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the press hydraulic cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
The scar on the sliding surface of the press hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the press hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.
The piston rod of the press hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.
Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.
Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.
