Norway hydraulic cylinder,large tonnage cylinder manufacturer,large tonnage cylinder(Norway large tonnage cylinder,produced by Hebei Hengyu company)
large tonnage cylinder are widely used in Norway,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed large tonnage cylinder for customers from Norway.
If the seal of the large tonnage cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and large tonnage cylinder, and the phenomenon of "pulling the large tonnage cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.
The large tonnage cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.
Before the large tonnage cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.
large tonnage cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the large tonnage 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.
Does the excavator use a hydraulic cylinder?
First, construction machinery is generally a hydraulic cylinder. Second, hydraulic transmission equipment is usually composed of four components, power, execution, control and auxiliary. And the hydraulic cylinder as a linear reciprocating motion or less than 360. Reciprocating motion of the hydraulic mechanism, simple structure, reliable work, is also widely used in the hydraulic system of the main actuator, it is the prime mover in the form of mechanical energy to drive the hydraulic pump produced by the liquid pressure energy, and then can be directly driven load for reciprocating movement or less than 360.
How to set the stroke of the cylinder?
Self-design should be based on product demand and practical application. The stroke of standard cylinder depends on the parameters the customer requires. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the speed and force of the linear motion. The piston of the hydraulic cylinder can complete the linear reciprocating movement, and the linear displacement of the output is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.
