What is Multistage Telescopic Cylinder?

Image
  Multistage hydraulic cylinders   or telescopic hydraulic cylinders are a recent innovation that have enabled us to customize and enhance the application of various types of machinery. They are used for a wide range of applications including cultivation, construction, and civil engineering. The primary advantage of the multi-stage hydraulic cylinder lies in the extension capabilities of its shaft, allowing it a far longer stroke when compared with other cylinders. It consists of various tubular rods known as sleeves. These sleeves (usually five or six) are of decreasing diameters and are placed within each other. Once pressure is pumped into the cylinder, the largest sleeve (also known as barrel or main) is the first to extend. It is followed by subsequent sleeves up to the last one (known as a plunger) until it reaches its maximum extension. The compact design of the multi-stage hydraulic cylinder allows it to enhance the function of process operations by proving particularl...

WHAT IS 40CR STEEL BAR

  40Cr steel is a kind of Chinese GB standard alloy steel for engineering and machinery purpose, and one of the most widely used steel grades. For 40Cr material hardness, specifications and equivalent, please see the table below.We are professional   40Cr Steel Bar   manufacturer. After quenching and tempering treatment, 40Cr steel has good comprehensive mechanical properties, low temperature impact toughness, low notch sensitivity, good hardenability, and high fatigue strength in cold oil. When water cooling, the complicated shape of the parts is prone to cracks, the cold bending plasticity is medium, and the cutting workability after normalizing is good, but the weldability is poor, should be preheated before welding, and is generally used in the state of quenching and tempering. 40CR STEEL CHEMICAL COMPOSITION   Chemical Composition (%) Grade C % Si Mn Cr 40Cr 0.37 – 0.44 0.17 – 0.37 0.5 – 0.8 0.80 – 1.10 MECHANICAL PROPERTIES OF 40CR ALLOY STEEL Tensile strength:...

What Is the Difference Between Cold Drawn Seamless Tubing and Hot Finished Seamless Tubing?

 Both  Cold Drawn Seamless Tube  and Hot Finished Seamless steel tubes provide strength and durability, but the process used to create each type of tubing provides slightly different advantages. Deciding whether Cold Drawn Seamless or Hot Finish Seamless is best will depend on how you plan to use the tubing for your application. Cold Drawn Seamless mechanical tubing is created by hot rolling SAE 1018 carbon steel, then drawing it at room temperature. During the drawing process, the pointed end of the tube is passed through a die. Force is used to stretch the steel into the desired thickness and shape and smooth the surface. This type of steel tubing meets ASTM A519 standards. It provides high yield strength, close tolerances and a smooth finish that is preferable for many mechanical applications. Hot Finished Seamless mechanical tubing is produced using SEA 1026 carbon steel and is manufactured using the same extrusion process, only without the final step of drawing the t...

Advantages of Welded Hydraulic Cylinders

Image
  A   hydraulic cylinder , or a linear motor, is a mechanical actuator used to give linear force through a linear stroke. It can be used in a variety of ways, and is commonly seen in manufacturing machinery, civil engineering, and construction equipment. There are two main types of hydraulic cylinders:  tie rod cylinders  and  welded body cylinders . Welded hydraulic cylinders offer a number of advantages over tie rod cylinders. Before understanding the advantages of a welded body cylinder, it is important to understand the difference between the two styles of hydraulic cylinders. Tie Rod Cylinders Tie rod hydraulic cylinders are not as complex in terms of design as welded body cylinders. Tie rod hydraulic cylinders use high-strength threaded steel rods in order to hold the end caps to the  cylinder barrel . Small bore cylinders typically have four tie rods whereas larger bore cylinders can have as many as twenty tie rods in order to withstand the forces pr...

What is a tie rod hydraulic cylinder?

  Tie rod hydraulic cylinders   are not as complex in terms of design as welded body cylinders. Tie rod hydraulic cylinders use high-strength  threaded steel rods  in order to hold the end caps to the  cylinder barrel . Small bore cylinders typically have four tie rods whereas larger bore cylinders can have as many as twenty tie rods in order to withstand the forces produced by the cylinder. Tie rod cylinders have been a go to for most agricultural applications for over 50 years. The hydraulic cylinder is used to transform the hydraulic fluid. energy into mechanical – output energy of the component. A hydraulic cylinder is a positive displacement motor of reciprocating motion. Hydraulic cylinders are widely used in the mobile and other technological industries. It’s low cost to manufacture and the fact that it isn’t welded makes it affordable for anyone needing a cylinder. Magister threaded double-acting tie rod hydraulic cylinders offer a heavy-duty design, cap...

What is a telescopic hydraulic cylinder?

Image
  Telescopic hydraulic cylinders , sometimes called multi-stage cylinders, are a type of linear actuator consisting of a series of tubular rods called sleeves. The sleeves (usually four or five) sequentially decrease in diameter and are nested inside of each other. Once hydraulic pressure is introduced to the cylinder, the largest sleeve (called the main or barrel) is extended first. Once the barrel has reached its maximum stroke, the next sleeve, usually referred to as a stage, begins to extend. This process continues until the cylinder reaches its last stage, called the plunger. There are two different types of telescopic hydraulic cylinders— single-acting cylinders  and double-acting cylinders. Single acting, by far the most common, work by using gravity or some other external force to retract the stages of the cylinder. As soon as pressure is released from the cylinder, the force of the load pushes oil out of the system and the cylinder retracts. While pneumatic telescopic...
