This article mainly introduces:

Panama hydraulic cylinder,pressure retaining cylinder manufacturer,pressure retaining cylinder

(Panama pressure retaining cylinder,produced by Hebei Hengyu company）

pressure retaining cylinder are widely used in Panama，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed pressure retaining cylinder for customers from Panama.

Introduction to pressure retaining cylinder:

The coordination of the sliding parts of the pressure retaining 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.

The viscosity of the working oil used in the pressure retaining 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.

The definition of the minimum stable speed refers to the minimum movement speed of the pressure retaining cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the pressure retaining cylinder that undertakes different work has different requirements for the minimum stable speed.

If the pressure retaining cylinder slips or crawls, please check whether there is astringency inside the pressure retaining cylinder, because the internal parts of the pressure retaining cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the pressure retaining cylinder changes with the different stroke position, and the slip or crawl occurs. 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 pressure retaining 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.

Answers to some questions about pressure retaining cylinder:

Is there a way to make the cylinder stop pushing when it hits something hard during the process of pushing?
The simplest solution is to press the stop switch, this switch has a mechanical type, touch the object on the action or send a stop signal, through the operation of the motor control cylinder; There is also an induction switch, that is, when the hydraulic cylinder expands to the range of the induction switch can sense the signal, it sends a signal to let the motor act, resulting in the corresponding action of the cylinder.

In hydraulic equipment, is the motor power related to the cylinder pressure holding time?
Irrelevant. The motor only drives the plunger in the hydraulic cylinder of the oil pump to extend out, and stops when the set pressure is reached; The length of the pressure holding time is related to the sealing degree of the hydraulic cylinder and the solenoid valve.
