What is the welded hydraulic cylinders

 A hydraulic cylinder,is a mechanical actuator used to give linear force through a linear stroke. It can be used in a variety of ways, and is commonly seen in manufacturing machinery, civil engineering, and construction equipment. There are two main types of hydraulic cylinders: tie rod cylinders and welded hydraulic cylinders. 

Tie Rod Cylinders

Tie rod hydraulic cylinders are not as complex in terms of design as welded body cylinders. Tie rod hydraulic cylinders use high-strength threaded steel rods in order to hold the end caps to the cylinder barrel. Small bore cylinders typically have four tie rods whereas larger bore cylinders can have as many as twenty tie rods in order to withstand the forces produced by the cylinder.

Welded Body Cylinders

Welded hydraulic cylinders have no tie rods. Instead, the barrel is welded directly to the end caps and the ports are welded to the barrel. The front rod gland is generally bolted or threaded into the cylinder barrel, which allows the piston rod assembly and the rod seals to be removed for service.

Tie rod hydraulic cylinder Advantages:

1) Easy to disassemble and repair;

2) Most of them are standard series, semi-finished products or finished products are in stock, and the delivery time is short.

Welded hydraulic cylinder Advantages:

1) The overall installation size is smaller than the drawbar cylinder;

2) The stroke rod cylinder can withstand greater pressure;

3) It is easier to customize, such as special oil port, special installation method, installation of lock valve, etc.

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...
