HOW TO MAKE CUSTOM TELESCOPIC CYLINDER

 Design factors are an essential part of the design process for custom telescopic cylinders. The designer needs to consider the balance between each positive effect against possible negative one to gain the best possible performance. Each design factor influences the other design factors, and the designer’s main task is to find the balance between those. Here we give a closer look at those factors.

1.The final operating environment

One essential piece of information concerning cylinder design is the environment where the cylinder will function. It’s the base for the material choices used in cylinders. These cylinders may work in harsh environmental conditions such as damp or sea areas, under great strain, and impurities. The temperatures may differ from -50 C° to + 200 C° degrees.

2. Lifetime goal – The strength calculation

A vital part of the hydraulic cylinder design process is the strength calculation. 

The strength calculations are performed at a certain pressure level, and the number of cycles can be seen as a result. If the desired result isn’t achieved, the plans are fine-tuned, the structures are reinforced and recalculated. The strength calculations must be able to be taken into account already at the design stage. The designer typically looks at safety factors at maximum pressure, fatigue life, and buckling. Extra information such as the hydraulic diagram of the machine and cylinder’s using purposes is an excellent aid for the design process.

3. Functions and features of a hydraulic cylinder

When starting the design process, the designer needs initial data and specific information on the functions and parts required for the hydraulic cylinder. Many applications might seem like they need special features, but most of them only need slight design modifications. This fact simplifies the process and reduces design costs. However, the functionality and features of hydraulic systems may differ significantly depending on their operational purpose and the conditions they will be used. For example, two seemingly similar cylinders might have been designed for completely different users and create different amounts of force depending on their application. 

4. Installation environment

The 3D model of the hydraulic cylinder gives accurate information about the environment in which the cylinder needs to act. The designer gets a clear picture of the machine and the space required for the cylinder functions. The information about the machine’s cylinders’ connection sizes and locations helps the designer get a full picture of the cylinder environment. The 3D model most often shows the cylinder’s connection sizes and the sites provided by the customer. The customer gets the 3D model to review the product in the operating environment. In some cases, we receive the 3D model of the application, but usually, the customer does the review themselves.

5. Cylinder’s oil flow, speed, and sliding distance

The cylinder movement speed (m/s), the oil flow (l/min), the sliding distance (m or km), and the stress accumulation are vital parts of the cylinder lifetime. All the information helps the designer to choose the right kind of seals and cylinder tube materials. How much force needs to be created is an essential part of the cylinder’s functionality.   

6. Test requirements

In most cases, when a client orders a custom hydraulic cylinder, there will be needs for hydraulic cylinder tests. These tests are often related to critical safety standards. These tests guarantee that the cylinder meets the actual machine’s safety standards and all the requirements have been taken into account. The cleanliness of the cylinder and the cylinder fluids, the fatigue measurements are examples of the test requirements. The flawless operation of the cylinder is critical for the entire system and operational safety.

How to deal with the scratch on the surface of hydraulic cylinder barrel

Image
As we all know,In the process of using the  hydraulic cylinder , the hydraulic cylinder barrel will be damaged,it is common that there will be scratch on the surface of the  honed tube , some customers will ignore these scratches, this to us is not responsible for the cylinder, when a small scratches in the cylinder,we usually take some tips to deal with them. 1.First,  to clean up the oil on the surface of our hydraulic cylinder barrel, then we will use the grinder machine to the surface treatment of the scratched part of our cylinder, at this time we have to grind the surface of the cylinder wall out of swallowtail groove. Although we have cleaned our cylinder at the beginning, at this time we need to clean the cylinder barrel further. At this time, we use anhydrous ethanol to clean the surface of the scratch repair of honed cylinder barrel. 2. We usually use special  repairing adhesive  to solve the scratches on the surface of  hydraulic cylinder barrel ...

Heat Treatments Of Seamless Steel Tube

Image
Heat treatment of  seamless steel tubes  is a process to improve the properties of metal materials and their products. Depending on the use, the material and its workpiece are heated to the appropriate temperature, insulated, and then cooled in different ways to alter the internal structure to achieve the desired performance. Heat treatment of seamless steel tubes is generally divided into annealing, normalizing, quenching, tempering, failure, chemical heat treatment and vacuum heat treatment. By heat treatment, the efficiency or life of the steel can be improved, and in some cases, more expensive special materials can be used instead of cheaper ordinary metal materials. The basic heat treatment methods of seamless steel tubes mainly include the following four forms: 1. Annealing Annealing is a process in which a seamless steel tube is heated to a slightly higher or lower critical temperature for a period of time (ie, heat preservation) and then slowly cooled. Common annealing...

HOW TO REPAIR THE HYDRAULIC CYLINDER ROD

  Hydraulic cylinders can be repaired, but you should never attempt these repairs on your own. Although hydraulic cylinders have a simple design, you must be familiar with them in order to efficiently repair them. When a technician performs hydraulic cylinder repairs, they take the entire mechanism apart and reassemble to find the root cause of the issue. COMMON POINTS OF HYDRAULIC CYLINDER FAILURE There are several common points of hydraulic cylinder failure. These include the piston, cylinder rod , seals, and head. PISTON The pistons in hydraulic cylinders are one of the most common points of failure. This is especially true in light-duty applications. The pistons used in light-duty applications are often made from aluminum, which wears out much more quickly than the steel used in heavy-duty applications. When checking pistons for failure, technicians will often measure the diameter of the piston. The piston’s diameter in relation to the bore directly affects the amount of hydra...
