(Spain swager cylinder,produced by Hengyu Group）
swager cylinder are widely used in Spain，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed swager cylinder for customers from Spain.
When the long-stroke swager cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in swager cylinder head seal damage, oil leakage, and piston sleep in the swager cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the swager cylinder; The piston and the piston rod are connected with a spherical joint.
When purchasing the swager cylinder, try to clarify the following parameters of the swager cylinder: A. swager cylinder diameter, rod diameter, stroke; B. Working pressure or swager cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right swager cylinder type can be found accurately and quickly.
When the swager cylinder needs to be stored for a period of time, please follow the recommended methods: The swager cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the swager cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil swager cylinder should not be in direct contact with water vapor for a long time. The swager cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the swager cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the swager cylinder Before working, the swager cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the swager cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
When installing the swager cylinder, the axial ends of the swager cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the swager cylinder, there is axial expansion. If the two ends of the swager cylinder are fixed, all parts of the swager cylinder will be deformed. When disassembling the swager cylinder, it is strictly forbidden to hammer the swager cylinder and the piston surface, such as the swager cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.
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.
There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.
