(Ecuador hydraulic press cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to hydraulic press cylinder:

The piston seal of the hydraulic press cylinder is the main element to prevent leakage in the hydraulic press cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

The hydraulic press 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 hydraulic press cylinder, bite. Elimination method: When installing the hydraulic press cylinder, ensure that the axis position of the hydraulic press cylinder is consistent with the direction of movement; Make the load borne by the hydraulic press cylinder as far as possible through the hydraulic press cylinder axis, to avoid the phenomenon of eccentricity.

When installing the hydraulic press cylinder pipe, the pipe should be cleaned after installation, and should not pass through the hydraulic press cylinder block, and the by-pass pipe must be installed in front of the oil port of the hydraulic press cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the hydraulic press cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the hydraulic press cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

If the hydraulic 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 hydraulic press cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow hydraulic press cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the hydraulic press cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the hydraulic press cylinder includes the leakage caused by excessive wear of the hydraulic 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 hydraulic press cylinder, and the phenomenon of "pulling the hydraulic 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.

Answers to some questions about hydraulic press cylinder:

What's the use of three oil pipes on the cylinder?
The cylinder usually has an upper and lower oil chamber, one is connected to the upper oil chamber, one is connected to the lower oil chamber, sometimes a hydraulic lock will be added, that is, a hydraulic control check valve to prevent accidents when the oil pipe breaks, so the third pipe should be the control oil pipe of the hydraulic control check valve.

How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest cylinder.
