Argentina hydraulic cylinder,spring return cylinder manufacturer,spring return cylinder

(Argentina spring return cylinder,produced by Hengyu Group）

spring return cylinder are widely used in Argentina，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed spring return cylinder for customers from Argentina.

Introduction to spring return cylinder:

When the initial action of the spring return cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the spring return cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

In the case of serious wear on the inner surface of the spring return cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the spring return cylinder manufacturing process for replacement. The spring return cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

The quality of the spring return cylinder can not be ignored in the purchase of the spring return cylinder. The spring return cylinder is the main component of the spring return 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. spring return 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 spring return cylinder is deep hole processing, which has always troubled the processing personnel.

spring return cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the spring return cylinder is placed for a period of time, the spring return cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

Answers to some questions about spring return cylinder:

What is the difference between hydraulic cylinder self-adjusting buffer and adjustable buffer?
If it is the buffer device inside the cylinder, then there are 4 basic forms, cylindrical buffer device, conical buffer device, variable throttle and adjustable flow groove. The biggest difference between the first three and the latter is that the latter can be adjusted through the external thimble to change the buffer strength, the first three mainly rely on the buffer device and buffer groove form to achieve the buffer (among them, the first type of buffer strength will not change, and the buffer strength of the two and three forms of buffer devices can be gradually increased).

Need to buy a hydraulic cylinder, now only know that the pressure needs to be between 20t and 50t. Two-way travel, how to determine the type of cylinder?
Important parameters of the cylinder: cylinder diameter, stroke, use pressure. First, the system pressure must be determined according to the precision of the operation of the application equipment, and the cylinder diameter can be determined by the force and system pressure. Then, according to how the equipment and the cylinder are installed and connected, determine the installation method of the cylinder and then determine the specific installation size, the size of the oil port, whether the buffer is needed and other details.
