(The Philippines large cylinder,produced by Hengyu Hydraulic Cylinder Factory）

large cylinder are widely used in The Philippines，because of long service life，smooth movement，high work efficiency.So our company has designed large cylinder for customers from The Philippines.

Introduction to large cylinder:

large cylinder hydraulic oil selection: The recommended working oil viscosity of the large cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

At the rated pressure, the thrust of the large cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the large cylinder is related to the diameter of the large cylinder, but not to the stroke of the large cylinder. Moreover, the larger the large cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the large cylinder.

The large cylinder is mainly composed of body, piston, piston rod, large cylinder head, large cylinder bottom, piston rod head and related auxiliary devices. The piston divides the large cylinder into two chambers, and moves reciprocally in the large 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 large cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the large 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 large 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 large cylinder bottom and the large cylinder head is serious, so the buffer deceleration should be set at both ends of the large cylinder The working medium of the large cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; large 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 large cylinder: The buffer structure of the large cylinder is to prevent the piston from colliding with the large cylinder head at the end of the stroke.

large cylinder and hydraulic station selection: Select the type and structure of the large cylinder according to the operation requirements of the main engine. According to the external load force borne by the large cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the large cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the large cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the large cylinder, the diameter of the piston and the piston rod.

Answers to some questions about large cylinder:

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.

Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
