(Pakistan baling press cylinder,produced by Hengyu Group）

baling press cylinder are widely used in Pakistan，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed baling press cylinder for customers from Pakistan.

Introduction to baling press cylinder:

When installing the baling press cylinder, the axial ends of the baling press cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the baling press cylinder, there is axial expansion. If the two ends of the baling press cylinder are fixed, all parts of the baling press cylinder will be deformed. When disassembling the baling press cylinder, it is strictly forbidden to hammer the baling press cylinder and the piston surface, such as the baling press 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.

The advantages and disadvantages of the baling press cylinder: the surface of the baling press cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the baling press cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

The quality of the baling press cylinder can not be ignored in the purchase of the baling press cylinder. The baling press cylinder is the main component of the baling press cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. baling press cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of baling press cylinder is deep hole processing, which has always troubled the processing personnel.

If the baling press cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the baling press cylinder. The internal parts of the baling press cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the baling press cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the baling press cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the baling press cylinder bore processing is out of whack. Because the piston and baling press cylinder, guide rail and piston rod are relative If the baling press cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling baling press cylinder weight composition and calculation. The weight of the baling press cylinder is composed of the baling press cylinder diameter, the outer diameter and weight of the baling press cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

Answers to some questions about baling press cylinder:

What is the function of the forklift truck cylinder and how does it work?
(1) In order to quickly and conveniently pick up the goods, the gantry needs to be tilted forward; In order to prevent the goods from falling, the door frame should be tilted backward to ensure the stability of the goods. The front and back tilt of the frame is accomplished by tilting the oil cylinder. (2) The inclined cylinder is composed of a piston, a cylinder block, a piston rod, an upper cover, a lower cover, a compression nut and a cover female and other main parts. (3) The inclined cylinder has two oil holes that can be interchanged into oil inlet and discharge holes. The cylinder is divided into a front cavity and a back cavity by a piston. The back cavity is filled with high-pressure oil when it tilts forward, and the front cavity is filled with high-pressure oil when it tilts backward.

What is st represented in the cylinder formula?
St is the original unit of kinematic viscosity, the abbreviation of Stokes, that is, Stokes, short for S. cm2/s has now been used. 1 s (St) = 10^-4m2/s.
