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

Introduction to press hydraulic cylinder:

The coordination of the sliding parts of the press hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

Regular maintenance of the press hydraulic cylinder includes: regular tightening, press hydraulic cylinder fastening screws and gland screws, press hydraulic cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the press hydraulic cylinder once a year. Clean regularly, the press hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.

The viscosity of the working oil used in the press hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

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

Answers to some questions about press hydraulic cylinder:

What does cylinder hob125*100 mean?
HOB is a series of hydraulic cylinder products, the use of pressure 14MPA, tie rod structure. 125 refers to the diameter of the cylinder and 100 refers to the stroke. The unit is millimeters.

What is the function of the Reza mounted master cylinder?
The role of the Resa-mounted master cylinder is to pump the concrete from the hopper to the delivery pipe and to provide sufficient concrete outlet pressure so that the concrete can reach the specified location.
