pressure retaining cylinder Sold to Paraguay

This article mainly introduces:

Paraguay hydraulic cylinder,pressure retaining cylinder manufacturer,pressure retaining cylinder

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

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

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 pressure retaining cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the pressure retaining cylinder, bite. Elimination method: When installing the pressure retaining cylinder, ensure that the axis position of the pressure retaining cylinder is consistent with the direction of movement; Make the load borne by the pressure retaining cylinder as far as possible through the pressure retaining cylinder axis, to avoid the phenomenon of eccentricity.

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.

Because of the slightly complex structure of the buffer pressure retaining cylinder, sometimes there will be problems, such as when the pressure retaining cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Answers to some questions about pressure retaining cylinder:

What are the main dimensions of the cylinder?
The main dimensions of the cylinder include: cylinder inner diameter, piston cylinder diameter, cylinder length, cylinder wall thickness, stroke, installation distance, etc.

How to limit cylinder push rod rotation?
In general, the push-rod rotation can be limited after the push-rod is connected to the pushed mechanism. For example, the push rod is hinged with the push mechanism, or the push mechanism itself is guided, which can limit the rotation of the push rod.
