plating press hydraulic cylinder are widely used in Tunisia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed plating press hydraulic cylinder for customers from Tunisia.

Introduction to plating press hydraulic cylinder:

The internal leakage of the plating press hydraulic cylinder is an important indicator to measure the quality of the plating press hydraulic cylinder: the internal leakage of the plating press hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the plating press hydraulic cylinder, so that the plating press hydraulic cylinder can not accurately and stably stop in a certain position of the plating press hydraulic cylinder, so it is one of the main indicators of the plating press hydraulic cylinder.

When the plating press hydraulic cylinder is installed, the piston and the plating press hydraulic cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the plating press hydraulic cylinder head boss is easy to cause scars when it hits the inner surface of the plating press hydraulic cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized plating press hydraulic cylinders, only careful and careful operation can be avoided.

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

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

Answers to some questions about plating press hydraulic cylinder:

How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.

How to disassemble the cylinder?
Generally speaking, it is not difficult to disassemble the hydraulic cylinder, as long as you are careful, but you often encounter some small trouble in the disassembly process, because the disassembly process is not correct. In fact, this can be avoided, as long as you follow below points. 1. Before removing the hydraulic cylinder, the hydraulic circuit should be relieved of pressure, otherwise, when the oil pipe connected with the cylinder is loosened, the high-pressure oil in the circuit will be rapidly ejected. When the hydraulic pressure comes back, the handwheel or pressure regulating screw at the relief valve should be loosened first, so that the pressure oil is unloaded, and then the power supply or power source is cut off, so that the hydraulic device stops running. 2. Disassembly should prevent damage to the top thread of the piston rod, the oil thread and the chrome layer on the piston rod surface.
