Hydraulic Testing Projects With China National Offshore Oil Corporation

Project Images Project Introduction 50-ton low height pancake hydraulic cylinders used in auger boring steerable rock system.Steerable head designed for boring through sand or soft rock with real-time steering adjustments made out of the pit with a hydraulic control system. The Steerable Rock System (SRS) is the auger boring market’s first steerable head designed to navigate not only solid rock but difficult fractured rock conditions as well. Engineered to operate in rock up to 25,000 psi, the SRS allows operators to keep bores online and grade even in the toughest ground conditions for an on-grade bore. On the drilling head, there is peace’s of small round pipe, that’s where the cylinders sit. There are 4 pcs 50-ton pancake hydraulic cylinders on each side(top, bottom, right, and left) of the steerable head for a total of 16pcs, it works when it’s drilling horizontally underground we use the cylinders to navigate the drilling head.

In hydraulic systems, hydraulic cylinders are widely used in a variety of scenarios such as heavy lifting operations, propulsion operations, and driving operations. In these systems, the synchronous operation of multiple hydraulic cylinders is an important part of ensuring the efficient and safe operation of the equipment. The synchronization of hydraulic cylinders can not only improve the efficiency of operations, but also avoid equipment damage caused by inconsistent movement. This article will explore in depth the principles of the synchronous movement of multiple hydraulic cylinders, common synchronization methods, technical challenges, and precautions during operation. 1. Working principle of hydraulic cylinder synchronization Hydraulic cylinder synchronization means that multiple cylinders extend or retract at the same speed and force at the same time. The core lies in the uniform distribution of hydraulic fluid and the precise control of pressure. The realization of synchronous operation depends on the following key factors: Fluid dynamics: The basic principle of the hydraulic system is to use the incompressibility of the liquid to convert pressure into power. The synchronous movement of the cylinder is achieved by controlling the direction and flow of the liquid flow. Load balancing: When multiple hydraulic cylinders share the load, ensure that each

Hydraulic cylinders are widely used in engineering machinery, machine tool equipment, automobile manufacturing, metallurgy and mining, aerospace and other fields. So, how are hydraulic cylinders produced? 1. Preliminary preparation 1.1 Design Hydraulic components and sealing components have different requirements in terms of dimensional tolerance, surface roughness, shape and position tolerance, etc. Therefore, the geometric accuracy of each component must be ensured and the correct seal must be selected during design. 1.2 Steel material selection: Commonly used steels are #20 steel, #45 steel, and 40Cr. The hardness of the steel is different, the applicable working conditions are different, and the price is also different, so comprehensive consideration is required. 2.The Production Processing 2.1 Cylinder body Generally, seamless steel pipes without bending or deformation are selected. In order to ensure its good toughness and plasticity, it needs to go through a series of processing. Cut the steel pipe into required length. Threads are machined on the inner walls of both ends of the steel pipe. Drill oil holes at appropriate locations and weld oil pipes. During the production of hydraulic cylinders, many processes such as cylinder barrels and piston rods require welding. High-precision welding machines can ensure welding quality.
