Pakistan hydraulic cylinder,double acting cylinder manufacturer,double acting cylinder(Pakistan double acting cylinder,produced by Hengyu Hydraulic Co., Ltd)
double acting cylinder are widely used in Pakistan,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed double acting cylinder for customers from Pakistan.
When installing the piston rod, 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 double acting cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.
double acting cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.
double acting cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards double acting cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the double acting cylinder guide is determined by the length of the stroke. Check the strength of double acting cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.
The definition of the minimum stable speed refers to the minimum movement speed of the double acting cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the double acting cylinder that undertakes different work has different requirements for the minimum stable speed.
How to select the 2.5T bearing cylinder and hydraulic pump?
2,5 ton load is not heavy, you can use the rated pressure of 16 mpa gear pump, neither waste nor save cost, load/pressure = cylinder diameter, preset pressure of 8 mpa, 2500 (kg) /80 (bar) =31.25 square centimeters, in the open =63 mm, cylinder diameter can be selected 63 mm, stroke according to the situation, Hydraulic pump select gear pump, if there is a speed requirement, in order to calculate the displacement, the motor power also needs to determine the displacement of the pump to calculate.
Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
