Estonia push bench hydraulic cylinder

(Estonia push bench hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

push bench hydraulic cylinder are widely used in Estonia,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed push bench hydraulic cylinder for customers from Estonia.

Introduction to push bench hydraulic cylinder:

Analysis of commonly used seals: The wear ring and slip ring commonly used on the push bench hydraulic cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

When the push bench hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the push bench hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the push bench hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the push bench hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair push bench hydraulic cylinder are not high.

push bench hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching push bench hydraulic cylinder block - fine boring push bench hydraulic cylinder block - grinding push bench hydraulic cylinder block. The rolling method is: broaching push bench hydraulic cylinder block - fine boring push bench hydraulic cylinder block - rolling push bench hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the push bench hydraulic cylinder block is about 1-2 days, rolling 1 meter of the push bench hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the push bench hydraulic cylinder increases by 25%. If the push bench hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality push bench hydraulic cylinders, you must take the rolling production process. After the push bench hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

When the long-stroke push bench hydraulic cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in push bench hydraulic cylinder head seal damage, oil leakage, and piston sleep in the push bench hydraulic 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 push bench hydraulic cylinder; The piston and the piston rod are connected with a spherical joint.

Answers to some questions about push bench hydraulic cylinder:

What is the cause of the deep scratch of the cylinder?
The following reasons can cause the cylinder to be scratched. 1: Hydraulic oil containing particulate impurities into the hydraulic cylinder, these particulate impurities stuck between the piston rod and the guide ring (or stuck between the piston and the inner wall of the cylinder), when the piston movement in the cylinder will scratch the piston rod, the phenomenon of the inner wall of the cylinder, the more particles, the larger the scratch marks the deeper and more obvious. 2: The body of the cylinder itself. Due to assembly or design reasons, the coaxial error between the piston rod, piston, cylinder, guide ring and other parts is too large, or the cylinder, piston rod straightness error is too large, so that the piston rod and the guide ring interference between the cylinder, this mechanical interference will certainly lose the piston rod or cylinder wall.

How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.
