Types of Parker Cylinder

Tie rod cylinders

Tie rod cylinders are typically low-pressure applications where cost-effectiveness is paramount. They are highly flexible and can fit into different machinery pieces. The design includes cylindrical heads and caps attached to the body by parallel tie rods.

Parker polycylinders

The parker polycylinder is a modification of the tie-rod cylinder, ideal for light to moderate-duty applications. Its primary distinction is the use of sturdy plastic end caps and a resilient aluminum extrusion for the barrel.

Welded cylinders

Welded cylinders have a permanent weld joining the head and barrel, which prevents any movement between these two parts. This makes them particularly sturdy and able to handle greater pressures compared to tie rod designs.

Mill-type cylinders

These cylinders have a bulky frame made of cast aluminum or ductile iron, which protects the internal components effectively. The frame is permanently secured to the end caps through a welding process, ensuring robust strength and stability.

Round cylinders

As the name suggests, components have a circular bore and plunger. Most of them are simple to construct and work with a few moving parts. This straightforward style often equals lower upkeep expenses. It also goes well with many different kinds of machines and equipment.

Square cylinders

The square cylinder body provides good balancing and stability, allowing for even force distribution during operation. Their plunger can easily accommodate hydraulic fluids. Besides, square cylinders are easily stackable.

Features of Parker Cylinder

Design features

Some cylinders have a double-acting design, while others have a unique construction that reduces wear and tear. This is the piston and rod assembly, which allows a fluid link between the piston and the cylinder walls. Parker's unique design features a low-friction seal that enables longer strokes and higher speeds.

Sizes

Parker offers small, medium, and large sizes. Small tie rod cylinders are about 1 to 2 inches in rod diameter, while large cylinders are over 2 inches. The medium sizes are between large and small. Sizes determine the pressure-bearing capacity and applications. Large cylinders are suitable for construction equipment like excavators, while small ones fit packaging machines.

Mounting options

Parker hydraulic cylinders support various mounting techniques for flexibility. This includes flange and foot mounting. They are mounted to the base or structure perpendicular to the axis of movement. Flange mounting has a rectangular metal plate with mounting holes on the cylinder. The cylinder is fixed to another part using the holes.

Stroke length

The stroke length of a cylinder is the distance traveled by the piston inside the cylinder. Parker hydraulic cylinders have different stroke lengths for distinct applications. In general, double-acting cylinders have a stroke length between 3 and 45 inches. Multi-stroke cylinders are up to 144 inches long.

Application of Parker Cylinder

Construction industry

Parker hydraulic rams are widely utilized in the construction industry. They can be used in large vertical and horizontal formwork systems to support heavy weights. Parker hydraulic cylinders are also used as vibrators to increase the compactness of concrete during casting.

Mining industry

Parker hydraulic cylinders are also widely used in the mining industry. They can be used in the mining industry to support heavy weights like in the construction industry. Hydraulic cylinders are also used as feeders to push ores down from stockpiles and hoppers.

Logistics and packaging industries

In the packaging industry, the parka hydraulic cylinder serves as the power source for the machine, providing propulsion and clamping force. Clamping operation and material handling are the two primary applications in the logistics industry.

Customizable Parker Cylinder

Parker cylinders can be customized to meet specific requirements. They are available in a variety of sizes and configurations, ensuring compatibility with different machines and applications. Parker cylinders come with a range of seal options, including high-temperature and high-pressure seals. These seals are designed to withstand harsh conditions and provide reliable performance.

FAQ

Q: How do hydraulic cylinders work?

A: Hydraulic cylinders are actuators that convert hydraulic energy (fluid pressure) into linear mechanical energy (force and motion). They have a piston housed in a cylinder. When the hydraulic fluid is pumped into the cylinder, it pushes the piston, causing it to move and perform work.

Q: What are the four main parts of a hydraulic cylinder?

A: A hydraulic cylinder consists of the following four main parts: the body, the piston, the rod, and the seals. The body houses the piston, the moving element that generates force.

Q: What are the differences between hydraulic and pneumatic cylinders?

A: Although hydraulic and pneumatic cylinders are linear actuators, they have different working mechanisms. A hydraulic cylinder uses pressurized liquid to generate motion and force. For high power, hydraulic cylinders are ideal for heavy-duty applications.

Q: What size are Parker cylinders?

A: Parker Custom Cylinders are highly sophisticated cylinders in bore sizes that range from 2” to 48” with single stage strokes in excess of 40 feet.

Q: How long should a hydraulic cylinder last?

A: On average, hydraulic cylinders are designed to have a lifespan of around 15 to 20 years. However, this can vary significantly depending on the specific application, the frequency of use, and the level of maintenance and care provided.

Q: How to keep a hydraulic cylinder from rusting?

A: A heavy coat of grease will provide several months of protection, but for a machine used only one season a year, it may be necessary to renew the grease every three to four months. Hydraulic cylinders can be ruined by pit rust if left extended and not protected.

Q: Can you lubricate a hydraulic cylinder?

A: The best way to extend the operating lifespan of your hydraulic cylinder is to ensure all rods and component parts are adequately lubricated to avoid friction and wear. Failure to do so can result in rust, pitting, and complete system failure.

Q: Can you fix a pitted hydraulic cylinder?

A: In some cases, a pitted hydraulic cylinder can be repaired by honing or reaming the cylinder walls. However, if the pitting is extensive, the cylinder may need to be replaced.

Q: Should hydraulic cylinders get hot?

A: Hydraulic pumps naturally generate heat when running. However, the temperature should never exceed 180 °F.
