Manufacturing hydraulic cylinders at Datong Hydraulic

DESIGN

The hydraulic cylinders first designed by a team of hydraulic cylinder engineers, taking into account the use of the hydraulic cylinder and the environment that it will be in. This dictates materials, coatings, seals and other specialist parts. Hydraulic systems are designed in compliance with any external legislation that relates to the industry that it is being designed for. The offshore industry in particular has a number of requirements, which Apex Hydraulics can design in compliance with.
 

MACHINE SHOP

Once the design has been finished, the machine shop engineers start producing the cylinder. Cylinder rods and other parts are bored to minutely accurate measurements using highly specialized machinery. Cylinder rods are chromed or coated with specialist coatings company such as Datong Group.
 

FITTING DEPARTMENT

The fitting department puts all the components together (rod, pistons, tubes and seals). Purchasing from a wide variety of high-quality manufacturers, Datong Hydraulics are not tied to any one product and are able to choose the most appropriate part for each cylinder. The fitting department assembles the cylinder, ready for inspection and testing.
 

INSPECTION AND TEST DEPARTMENT

The in-house inspection department offers rigorous testing of all hydraulic cylinders before they are approved for the client. They perform pressure, pull and load tests as required. Datong are able to facilitate all third-party inspection agencies that may be required for offshore work, including DNV-GL, ABS and Lloyds Register.
 

PAINTING SHOP

 
Parts are spray painted in house. They can be painted to any required standards. Paint standards for offshore hydraulic cylinders are particularly specialised, with Norsok providing a range of that is typically approved by inspection agencies. At the point of painting, company logos or details can be added.

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...
