(Croatia swager cylinder,produced by Hengyu Hydraulic Co., Ltd）

swager cylinder are widely used in Croatia，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed swager cylinder for customers from Croatia.

Introduction to swager cylinder:

Before purchasing the swager cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

The quality of the swager cylinder can not be ignored in the purchase of the swager cylinder. The swager cylinder is the main component of the swager cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. swager cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of swager cylinder is deep hole processing, which has always troubled the processing personnel.

swager cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the swager cylinder prone to misoperation or action failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

swager cylinder and hydraulic station selection: Select the type and structure of the swager cylinder according to the operation requirements of the main engine. According to the external load force borne by the swager cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the swager cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the swager cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the swager cylinder, the diameter of the piston and the piston rod.

Answers to some questions about swager cylinder:

When the cylinder is tested, why can't the pressure be maintained with the balance valve?
Because the oil into the oil chamber through the hydraulic lock on the control oil circuit through the other side of the spool, the original valve is designed in this way. It locks the circuit after the oil supply circuit loses pressure, on the contrary, if you keep supplying pressure, it is always in the state of opening the other side of the one-way spool. So this valve can't be used in the test.

How to calculate hydraulic cylinder flow?
Effective area of the cylinder x stroke = volume usually in liters. Volume/estimated total travel time (converted to minutes) = oil flow rate.
