(Angola clamp type cylinder,produced by Hebei Hengyu company）

clamp type cylinder are widely used in Angola，because of long service life，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed clamp type cylinder for customers from Angola.

Introduction to clamp type cylinder:

The daily inspection of the clamp type cylinder includes: checking the connection of the clamp type cylinder and the pipe joint for leaks. Check the clamp type cylinder rod for leaks. Check the clamp type cylinder connection for leaks. When the clamp type cylinder moves, the work is normal and smooth. Whether the clamp type cylinder has internal leakage.

The clamp type cylinder is mainly composed of body, piston, piston rod, clamp type cylinder head, clamp type cylinder bottom, piston rod head and related auxiliary devices. The piston divides the clamp type cylinder into two chambers, and moves reciprocally in the clamp type cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the clamp type cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the clamp type cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the clamp type cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the clamp type cylinder bottom and the clamp type cylinder head is serious, so the buffer deceleration should be set at both ends of the clamp type cylinder The working medium of the clamp type cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; clamp type cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the clamp type cylinder: The buffer structure of the clamp type cylinder is to prevent the piston from colliding with the clamp type cylinder head at the end of the stroke.

If the piston rod and clamp type cylinder are stuck or the clamp type cylinder is blocked, at this time, no matter how to operate, the clamp type cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the clamp type cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The assembly work of the clamp type cylinder has a great impact on the quality of the clamp type cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

Answers to some questions about clamp type cylinder:

Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.
