(Kuwait press hydraulic cylinder,produced by Hengyu Group）

press hydraulic cylinder are widely used in Kuwait，because of powerful torque，simple structure and reliable operation，clever hydraulic energy conversion.So our company has designed press hydraulic cylinder for customers from Kuwait.

Introduction to press hydraulic cylinder:

press hydraulic cylinders in series, parallel and series parallel. Series: In the press hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the press hydraulic cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the press hydraulic cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the press hydraulic cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

If it is found that the press hydraulic cylinder lubrication is poor or the press hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the press hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the press hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the press hydraulic cylinder center line. In this way, when the piston works in the press hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the press hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

When installing the press hydraulic cylinder, the axial ends of the press hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the press hydraulic cylinder, there is axial expansion. If the two ends of the press hydraulic cylinder are fixed, all parts of the press hydraulic cylinder will be deformed. When disassembling the press hydraulic cylinder, it is strictly forbidden to hammer the press hydraulic cylinder and the piston surface, such as the press hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

The machining accuracy of the press hydraulic cylinder depends on the level of equipment, production technology and testing means. press hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

Answers to some questions about press hydraulic cylinder:

How big gear pump need to use for 60*100 cylinder?
One cylinder size alone does not determine the size of the pump used. Choose the size of the pump, at least to know 1, the size of the load is how much, by the size of the load and the size of the cylinder and other conditions can be calculated the pressure required by the hydraulic system. 2. Speed of operation. From this speed and cylinder size, the required flow rate of the system is calculated. The relevant parameters of the pump can be selected by the pressure and flow rate to determine what kind of pump is required.

When the hydraulic cylinder changes from fast to slow, how can the slow speed become more even and the speed can be adjusted?
Reversing valve set 2 reversing valves. The back of one valve goes directly to the cylinder, running at full speed for fast action. Add a speed control valve behind the other valve, and then connect to the cylinder to achieve slow action, you can adjust the opening of the speed control valve, to achieve the speed of the cylinder can be adjusted. An import speed control valve to more than 1,000 yuan, if you think it is too expensive, you can also use the throttle valve instead. However, the throttle valve is greatly affected by the load change.
