(Paraguay supporting cylinder,produced by Hengyu Hydraulic Co., Ltd）

supporting cylinder are widely used in Paraguay，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed supporting cylinder for customers from Paraguay.

Introduction to supporting cylinder:

supporting cylinder installation precautions: Before installing the supporting cylinder into the system, the parameters on the supporting cylinder label should be compared with the parameters when ordering. The base of the supporting cylinder must have sufficient stiffness, otherwise the supporting cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

When the supporting cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the supporting cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil supporting cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical supporting cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the supporting cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

The definition of the minimum starting pressure of the supporting cylinder refers to the minimum working pressure of the supporting cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the supporting cylinder parts and the size of the sealing friction.

When the long-stroke supporting cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in supporting cylinder head seal damage, oil leakage, and piston sleep in the supporting cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the supporting cylinder; The piston and the piston rod are connected with a spherical joint.

Answers to some questions about supporting cylinder:

Two cylinders have a reversing control, if the load of the two cylinders is not the same, how to ensure their synchronization?
The piston rod of the cylinder is required to extend synchronization: install A shunt collector valve or synchronous motor at port A of the direction control valve, and then connect the two outlets of the shunt collector valve to the rod-free cavity of the two cylinders respectively. It is required that the outlet of the diverter collector valve is connected to the rod cavity of the two cylinders respectively when the piston rod is withdrawn in synchronization. The synchronization performance depends on the quality of the diverter valve and the leakage of the hydraulic system.

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.
