Almost all mechanical applications in industry and allied utilities have been relying on the technology of hydraulics these days. Consequently, the products and service from double-acting hydraulic cylinders suppliers have also touched new heights. The usage of these cylinders is multi-fold.
Technically, in a double-acting cylinder, the working fluid acts alternately on both sides of the piston. So as to link the piston in a double-acting cylinder to an external mechanism like a crank shaft, a hole is provided in one end of the cylinder for the piston rod. This is annexed with a gland also named stuffing box to prevent escape of the working fluid. Thus, these double-acting cylinders are common in steam engines and turbines. On the same principle, hydraulic and pneumatic cylinders use them so as to produce an impact in both the directions.
To meet the rise in demand for double-acting cylinders, manufacturers of hydraulic systems have sped up the capacity of their production. The sectors of agriculture, earth-moving machinery, waste management, material handling, mining as well as conventional power and renewable energy are among the beneficiaries of these efforts.
To this end, the quality-conscious manufacturers maintain close liaison with the customers to ascertain the specific end usage of their products. Different hydraulics companies have taken a step ahead in offering apt solution to the user industries and services. Their engineers have revolutionised the process of production with the aid of advanced 3D design software and CADEM systems. The success of missile technology in the armament segment of defence programme could be attributed to the commendable inputs provided by this unit of hydraulics industry. For instance, the military application cylinders had to withstand -40° C ambient temperatures. Likewise, other products have been the multistage double-acting telescopic cylinder, high precision missile launcher cylinders suitable for 380mm and bigger ore press cylinders.
There is also constant demand for products which are not listed in the conventional matrix. To this end, the engineers have to design and develop custom hydraulic cylinders that are tested under various conditions. These cylinders range from welded, riveted or threaded with multi-stage applications in pneumatic configuration and allied systems.
While conceptualizing custom hydraulic cylinder solutions, the manufactures are expected to maintain top most quality norms. These are as per ISO 9001:2008, ISO1400:2004, OHSAS 18001:2007 and ISO 3834 Part -2 certification designed for the client’s specific application right from the raw material to the end product. Ratings in terms of energy efficiency are also taken into account for these products.
Often, the manufacturer may have to re-equip the production facilities while meeting the demands of custom oriented cylinders. Apart from the raw materials, the tool room and assorted shop floor systems are updated to enable efficient process of production. Similarly, when the company is one of the OEMs of a material handling system or utility like earth-moving machinery that is meant for export, they cylinders are designed and manufactured in tune with the importing country’s prescribed specifications.
