Finland hydraulic cylinder,baling press cylinder manufacturer,baling press cylinder(Finland baling press cylinder,produced by Hengyu Hydraulic Co., Ltd)
baling press cylinder are widely used in Finland,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed baling press cylinder for customers from Finland.
Do not regularly check the damage of the chrome layer of the baling press cylinder: completely extend the baling press cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the baling press cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the baling press cylinder seal. Welding slag is strictly prohibited on the surface of the baling press cylinder.
The coordination of the sliding parts of the baling press 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.
When the control pressure of the hydraulic system is too low, the baling press cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.
If the baling press cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the baling press cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow baling press cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the baling press cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the baling press cylinder includes the leakage caused by excessive wear of the baling press cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials 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 baling press cylinder, and the phenomenon of "pulling the baling press cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.
How to distinguish cylinder rod head and cylinder bottom?
One end of the piston rod can be telescopic is the rod head, and the one behind is the bottom of the cylinder, which is the single rod cylinder.
How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation 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 valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.
