(Bangladesh boarding axle cylinder,produced by Hengyu Group）

boarding axle cylinder are widely used in Bangladesh，because of simple structure and reliable operation，long service life，excellent fatigue and impact resistance.So our company has designed boarding axle cylinder for customers from Bangladesh.

Introduction to boarding axle cylinder:

When the hydraulic oil is not pumped into the boarding axle cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the boarding axle cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

1, the hydraulic machinery should be kept clean, in order to prevent dust and debris from falling into the oil, the tank should be sealed. 2, the oil in the tank should be replaced regularly according to the working condition. When changing the oil, the dirt and impurities accumulated at the bottom of the tank should be removed and the tank should be cleaned. 3, hydraulic oil, oil drums should be set in a clean and safe place to strengthen management. The oil drum, oil filter, oil funnel, oil pipe, etc. used should be kept clean. The oil drums for loading hydraulic oil must be cleaned in advance, and the oil drums should be dedicated and not mixed with other oil drums.

The difference between the integral boarding axle cylinder and the split boarding axle cylinder: The integral boarding axle cylinder and the split boarding axle cylinder in the boarding axle cylinder are two different boarding axle cylinders, and they are very different. The whole boarding axle cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split boarding axle cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and boarding axle cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

The pressure of the sliding surface of the boarding axle cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the boarding axle cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

Answers to some questions about boarding axle cylinder:

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.

To achieve the same stroke, which is better, hydraulic cylinder or lead screw?
If there is batch action, then the hydraulic pressure is better. Hydraulic: smooth operation, no lubrication, easy control, high control accuracy (can use proportional or servo system), the key is to manually control, but certainly to support the hydraulic system, for a single action must cost. Maintenance costs are also high. Lead screw: simple structure, easy to achieve, convenient maintenance, but must be lubricated, can not be manual, or manual control is inconvenient. See where it is used, if it is used in high-precision occasions, it must only be hydraulic, because the lead screw has a gap. There are many hydraulic actions, the hydraulic system itself must be prepared, then the use of hydraulic pressure is also very economical.
