Panama hydraulic cylinder,unidirectional cylinder manufacturer,unidirectional cylinder

(Panama unidirectional cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to unidirectional cylinder:

When producing oil unidirectional cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

How to repair the unidirectional cylinder body when it is damaged: When the unidirectional cylinder has trace deformation and shallow tensile marks, the unidirectional cylinder is repaired by strong honing process. The heavy honing process can repair unidirectional cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the unidirectional cylinder can meet the technical requirements.

In order to ensure the service life of the unidirectional cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

The meaning of the unidirectional cylinder model marked by the unidirectional cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the unidirectional cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the unidirectional cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

Answers to some questions about unidirectional cylinder:

How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.

How do hydraulic equipment and hydraulic cylinders maintain a certain pressure after pressing to a certain position?
There are several methods. 1. You can use a constant pressure variable pump to adjust the control pressure of the pump to the pressure required by the cylinder, so that when the cylinder is in place, the pump uses the minimum flow rate to maintain the pressure, and the system is more energy saving. 2. If the pressure is maintained for a short time, a hydraulic control check valve can be added to the oil inlet end of the cylinder to close the cylinder and maintain the pressure. If the volume of the cylinder is large, an accumulator can be added between the valve and the cylinder to maintain pressure for 10-30 minutes. 3. You can add a small flow pump, the large pump after unloading, the small pump has been running, specifically for maintaining pressure.
