About Double Acting Hydraulic Cylinders
Double-acting hydraulic cylinders are considered to be more efficient hydraulic motors than single-acting hydraulic cylinders. In double-acting hydraulic cylinders, the force is transmitted in both directions of rod movement. These types of hydraulic cylinders are more functional. They are more widely used in industrial production and are most often responsible for lifting and lowering movements in any mechanism. This type of hydraulic cylinders has a more complex design, because it is necessary to make an additional section of the hydraulic fluid supply to provide the return stroke of the piston with the required force.
Most often, double-acting hydraulic cylinders are used in equipment that works both in difficult conditions and under constant load, as well as in equipment that has quite a wide range of applications in our normal life. Such working conditions cause a high probability of failure. Therefore, the production of hydraulic cylinder components must be made of high quality materials. Such as high-alloy carbon steel, and the surface of the rod should be very durable.
The use of rod hydraulic cylinders can be roughly divided into three main types:
- - Using as a drive for all kinds of various of lever mechanisms (a good example is an excavator bucket)
- - Setting of operating mechanisms in the right position for work (eg, advancing of crane legs for its steady position)
- - Moving mechanisms that perform work (bulldozers or graders)
Today, it is hard to find an area where these simple and reliable devices are not used. From utilities (snow plows and other special equipment) to the use of hydraulic cylinders in aerospace. The simplest example of the use of a hydraulic cylinder in everyday life is the use of a car jack, which is a classic hydraulic rod cylinder.
Production of double acting hydraulic cylinders
All customers of our company demand very high quality of our products. Our technical department takes a very close look at the customer's technical requirements before starting the production process. We use state of the art, high precision equipment and software with 3D modeling capability to produce double acting hydraulic cylinders. Our skilled and experienced production staff carefully study every detail of our customers' specifications. Due to our manufacturing capabilities, we have gained great confidence from our customers in the production of non-standard double acting hydraulic cylinders.
We have a lot of experience in the production of single acting and double acting hydraulic cylinders in our practice. A single-acting cylinder is, we would say, the classic design. We consider the production of double rod hydraulic cylinders to be a more interesting option. This type of hydraulic cylinder solves problems where you need the same force for the forward and backward stroke of the rod in your equipment. It also requires the rods to extend the same distance on opposite sides of the cylinder. This type of hydraulic cylinder is very often used in steering gears of large machinery.
Hydraulic cylinders to your drawings
Need to manufacture a hydraulic cylinder? We can modify any parameter to your requirements and even produce a hydraulic cylinder of non-standard design.
Our hydraulic cylinder manufacturing process can be divided into several stages:
- Obtaining and studying drawings. Careful study of all technical documentation, technical requirements for the finished product, close communication with the customer to clarify all the fine details and nuances before starting production.
- Components for production. We have established reliable supply channels of quality components and raw materials. Due to our close and long-term cooperation with reliable partners, we have priority in supply, which allows us to start production in a shorter time.
- Production of hydraulic cylinder parts. All hydraulic cylinder parts are machined on high-precision CNC machines so that the machining accuracy meets all the requirements of customer drawings.
- Assembly of hydraulic cylinders. All welding operations are carried out with the latest equipment and under careful control to avoid cracks in the welds and welding defects. All parts with welds are subjected to additional leakage and strength tests, and additional customer requirements can also be tested. All welds are cleaned with special machines.
- Painting of hydraulic cylinders. We use environmentally friendly painting lines for standard and special painting of hydraulic cylinders. All hydraulic cylinders are cleaned prior to painting. After cleaning, primer and paint are applied. If required by the customer, two coats of primer can be applied to increase the strength of the paint. Also at the customer's request, several layers of paint can be applied and the customer's logo can be drawn.
- Inspection of assembled hydraulic cylinders. All hydraulic cylinders produced by our company are subjected to compulsory factory tests or tests according to the customer's test program.
Quality control of hydraulic cylinders
Hydraulic Cylinder Testing
Learn more about our quality control and hydraulic cylinder testing services.
Eurobalt carries out thorough quality control at each stage of production of double acting hydraulic cylinders. During the manufacturing process of the components, the accuracy of the sleeves, rods and pistons is checked, as well as the thickness and hardness of the rod coating and the purity of the hydraulic oil. All welds are checked for strength and tightness. All assembled hydraulic cylinders are necessarily tested for tightness under pressure that can exceed the working pressure by 1.2 to 2.5 times.
Prior to shipment to the customer, every batch we produce is guaranteed to pass a complete quality control and meet the customer's specifications.
