Hydraulic barrels are the cylindrical parts of a hydraulic cylinder. Therefore, there are various kinds of hydraulic cylinder barrels, including:
This type of hydraulic cylinder barrel consists of a single chamber where hydraulic fluid is pressurized. Then the fluid is forced into the chamber, which extends the piston. Thus, the piston provides a powerful force for heavy operations.
As a note, these HC barrels are extensively used in lifting, pressing, and construction work applications built to produce high pressure and hold large fluid volumes.
This barrel is designed with two chambers divided by a piston. The pistons on both ends help create a double force when fluid enters one or both of the chambers.
Hydraulic cylinders with two-stage telescoping barrels are often employed in construction equipment. This is due to their ability to reach larger extending strokes while retaining compactness during transportation.
Manufactured from strong and durable materials like stainless steel, this barrel type is well suited for corrosive or extreme environment applications. In addition, it provides extended service to the cylinder.
Aside from that, there is a barrel with chrome-plating inner surfaces. This helps to reduce wear and corrosion on the cylinder barrel. Hence, leading to increased longevity and smooth piston operation. Normally, chrome-plated barrels are ideal for environments where the cylinder gets exposed to hostile chemicals or weather conditions.
Lastly, there is a telescoping barrel. It consists of multiple nested sections rather than a single or double section. This allows the hydraulic cylinder to extend further. Double-acting barrels enable both sides of the piston to be pressurized, allowing controlled movement in either direction.
In summary, telescoping barrels are used in applications requiring variable extension lengths, such as in garbage trucks and construction machinery.
As previously mentioned, there are various types of hydraulic cylinder barrels. Thus, each comes with unique requirements for durability in a specific application. However, some factors play a significant role in what makes a hydraulic cylinder barrel durable.
For starters, a hydraulic cylinder barrel must attain high strength to bear the pressures produced by hydraulic fluids without bowing, cracking, or caving in. Secondly, a hydraulics barrel must be resistant to corrosion to avoid the internal fluid and external factors like rust or oxidation damaging the structure.
In addition, durable hydraulic cylinders should be fatigue-resistant. This means the cylinder material can endure repeated pressure cycles without developing cracks or weaknesses over time.
Internal smoothness is a key factor for durability and efficiency. This is because a smooth internal surface minimizes turbulence, wear, and friction. Lastly, high durability barrels are designed to resist extreme temperatures, which can cause material expansions, weaken the structure, and, in the end, cause system failure.
To meet the above requirements, hydraulic cylinder barrels are manufactured with the following materials:
As noted, stainless steel is used extensively in barrels to provide high strength, resist wear, and avoid corrosion. Depending on the application, this steel comes in 304 or 316 grades.
304-grade is ideal for moderate environments, while 316-grade is reserved for hostile environments due to its nickel and molybdenum content. Stainless steel 316 is also commonly found in marine or chemical industry use due to its exemplary corrosion resistance.
Another material used to manufacture hydraulic cylinder barrels is high-strength steel alloy, which comprises normal steel tagged as low alloy. Alloy steel comes with increased resistance to fatigue, wear, and thermal effects. This makes it ideal for high-stress applications.
After that, there is mild steel. It is the most preferred choice for the inner and outer surfaces of a barrel because of its cost-effectiveness and ease of manufacture. However, mild steel is prone to rusting if not protected. Therefore, it is coated with chromium, zinc, or painted to give it corrosion resistance.
Lastly, aluminum alloy as a material offers lightweight without sacrificing strength, making it ideal for mobile applications. It can either be anodized or coated to increase its resistance to corrosion and wear.
The below commercial use cases demonstrate the versatility of hydraulic cylinder barrels:
Double-acting hydraulic cylinder barrels, like most hydraulic parts, have a home in the manufacturing industry. The reason being they are extensively incorporated into machinery used for metal stamping, molding, and other high-force operations. In these places, the barrels help maintain pressure and precision, improving production efficiency and equipment longevity.
Hydraulic barrel applies a powerful controlled force for heavy lifting and pushing in the construction industry. Hence, in this space, they are primarily found in the large machinery like excavators, cranes, and bulldozers.
Here, the hydraulic barrels support the movements of arms, booms, and buckets. They achieve this by transforming hydraulic pressure into mechanical power.
In the mining industry, electric hydraulic cylinders are the go-to component in heavy equipment used for digging, hauling, and transporting materials like ore and coal. In this harsh environment, cylinder barrels must withstand extreme pressures, abrasive materials, and adverse weather conditions. Hence, they require the highest durability and reliability standards.
Hydraulic barrels provide the necessary force and control to operate large gates, pumps, and valves in the water treatment and wastewater management business. They are key components in the machinery used to manage and treat large quantities of water and sewage.
These barrels are integral components in the automotive industry. They are used in vehicles for braking systems, lifts, and other heavy machinery. Hence, the hydraulic barrels help control movements and apply forces smoothly and accurately.
Be it in agriculture, aerospace, marine, or any other industry, hydraulic barrels are incorporated into cylinders for stable working performance. So, they are crucial components widely utilized in a variety of commercial sectors to accomplish successful large force and motion control in many operations.
Hydraulic cylinder barrels are used to lift and lower the vehicle in the transportation industry. Some common vehicles that use this setup include trucks, buses, and railway cars.
In this space, electro hydraulic cylinders are preferred because they can be powered by batteries and used in places where motors cannot be present. For instance, they are used in lifting platforms that service heights inaccessible by staircases.
Hydraulic cylinder barrels are commonly used with other hydraulic parts like hydraulic cylinder end caps in a construction workspace. For example, they power the loader bucket on a front-end loader, enabling it to scoop and dump materials like sand, gravel, and even small rocks.
Lastly, hydraulic barrels are used in large mechanical pressing equipment to provide even pressure on the materials being pressed. The pressure helps shape, mold, or compress the materials without applying direct human effort.
The following tips will come in handy when purchasing the hydraulic cylinder barrel.
As explained earlier, hydraulic cylinder barrels are used in many commercial applications. Therefore, consider the client’s typical operational needs and space constraints to determine the hydraulic cylinder size and specifications that will suit them.
Next, opt for a reliable hydraulic barrel manufacturer with glowing reviews and a proven record of accomplishment making premium products. Hydraulics barrel suppliers take wholesale hydraulic parts from these manufacturers, put them together, and sell them as a unit.
So, they should get them from reputable hydraulics barrel manufacturers like Jiayi, Jinjing, and others.
After that, narrow down the cylindrical barrels to those that are within the client’s budget range. Then, compare the prices of similar-kinded hydraulic cylinder barrels across various shops. This helps in getting the best deals and possibly discounts.
Lastly, prioritize quality when cost-cutting. Avoid any low-quality hydraulic barrels with poor or thin-walled construction that will bow easily and mishandle the immense hydraulic pressure. One, they are dangerous. Two, they can cause expensive equipment failure and compromise product safety.
As a reminder, both stainless steel and chrome-plated cylindrical barrels are highly favorable in construction hydraulics. Yet, stainless steel is usually recognized as the most widely used due to its strength, corrosion resistance, and durability. Hence, it is ideal for the harsh conditions commonly found in construction.
Creation of fatigue resistance, corrosion resistance, smooth inner surface, high strength, and ability to withstand extreme temperatures are the main factors that help a hydraulic cylinder barrel’s durability.
Yes. Manufacturers usually provide maintenance guidelines for their products. Regular maintenance helps to ensure the long-term performance and reliability of the hydraulic cylinder barrel. Common maintenance practices include inspecting for wear and damage, lubricating the internal surfaces, checking seals for leaks, and keeping the area clean of debris and moisture.
Among others, the most effective chrome-plating treatment on the inner surfaces of a hydraulic cylinder barrel reduces wear and corrosion. Additionally, anodizing or coating the exterior surface improves the barrel's endurance to hostile environmental elements, increasing its lifespan.
