Hydraulic Testing Projects With China National Offshore Oil Corporation

RIVERLAKE ZJ9 pile load testing power pack is a plc controlled pile load testing system,which can control,display,record and download the real-time pressure of the cylinders,real-time tonnage of the output force,real-time pressure of the power pack,real-time load testing time.In this project,our ZJ9 power station worked with 9 units HCRL30012 double acting lock nut hydraulic cylinders to generate a Max. total output force of 2700 tons.Beside above features,we can even built in bluetooth load cell and bluetooth dial gauge sensors to our pile load equipment to display and record the real-time load data from load cells and real-time pile displacement data from the dial gauge.

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.

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.
