Bolivia stern plate hydraulic cylinder

(Bolivia stern plate hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

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

Introduction to stern plate hydraulic cylinder:

After the stern plate hydraulic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

When the stern plate hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The stern plate hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the stern plate hydraulic 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 stern plate hydraulic cylinder should not be in direct contact with water vapor for a long time. The stern plate hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the stern plate hydraulic 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 stern plate hydraulic cylinder Before working, the stern plate hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the stern plate hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

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

The piston rod of the stern plate hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

Answers to some questions about stern plate hydraulic cylinder:

Hydraulic cylinder application areas?
1, in the machine tool industry, 85% of the machine tool transmission system adopts hydraulic transmission and control. Such as grinding machine, milling machine, planer, broaching machine, press, shearing machine, and combined machine tools. 2, in the metallurgical industry, electric furnace control system, rolling mill control system, open furnace charging, converter control, blast furnace control, strip deviation and constant tension device are all using hydraulic cylinders. 3, in the construction machinery, the general use of hydraulic transmission, such as excavators, tire loaders, truck cranes, crawler bulldozers, tire cranes, self-propelled scrapers, graders and vibration rollers. 4, in agricultural machinery, the use of hydraulic cylinders is also widely used, such as combine harvesters, tractors and so on.

How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.
