(The Philippines roller press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
roller press hydraulic cylinder are widely used in The Philippines，because of no transmission clearance，clever hydraulic energy conversion，powerful torque.So our company has designed roller press hydraulic cylinder for customers from The Philippines.
In use, the roller press hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the roller press hydraulic cylinder.
At the rated pressure, the thrust of the roller press hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the roller press hydraulic cylinder is related to the diameter of the roller press hydraulic cylinder, but not to the stroke of the roller press hydraulic cylinder. Moreover, the larger the roller press hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the roller press hydraulic cylinder.
When the initial action of the roller press hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the roller press hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.
The roller press hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure roller press hydraulic cylinder can use 20 steel pipe, and the high pressure roller press hydraulic cylinder can use 45 steel pipe.
How does the cylinder of the shearing machine work?
Plate shear is a machine that cuts a sheet with a reciprocating straight motion from one blade to another. Through the moving upper blade and the fixed lower blade, the shear force is applied to the metal sheet of various thicknesses with a reasonable blade gap, so that the sheet is broken and separated according to the required size. Shearing machine belongs to one of the forging machinery, the main role is the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment. Working principle: The hydraulic system is used to drive the hydraulic cylinder to output a strong shear force to complete the shearing work.
By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.
