Xiamen Senhengyuan gives reliable piston pumps. They offer quality assurance and technical support. This helps you get the best results for your projects.
A piston pump helps move fluids with strong force and steady flow. It works by using a piston inside a cylinder to push liquid. When the piston goes up, it pulls fluid into the cylinder. When the piston goes down, it pushes the fluid out. This movement happens in machines that need high pressure and a steady flow.
A hydraulic piston pump is used in big machines and equipment. It gives strong power and works well for tough jobs. There are two main kinds. In an axial piston pump, pistons move up and down as the shaft turns. This makes the fluid move in and out in a steady way. In a radial piston pump, pistons are in a circle and move in and out as the camshaft spins. Both types help keep fluid moving smoothly and with power.
A piston pump is part of the positive displacement pump group. You pick these pumps when you want steady flow, even if pressure changes. They work well with thick fluids and can handle hard jobs without losing power.
Here is a table that shows how positive displacement pumps and non-positive displacement pumps are different:
Feature | Positive Displacement Pumps | Non-Positive Displacement Pumps |
|---|---|---|
Pressure | Work in high pressure, up to 800 bar | Good for low pressure, up to 20 bar |
Efficiency | Get better with higher pressure | Peak at one point, drop at high/low |
Viscosity | Improve with thicker fluids | Drop with thicker fluids |
Performance | Give steady flow, even with changes | Flow changes when pressure changes |
A positive displacement pump keeps the flow steady. This is helpful when you work with thick fluids or fluids with solids. You can use these pumps for many kinds of fluids and keep your system working well.
Positive displacement pumps help keep the flow steady, which is good for thick fluids.
You can use them for fluids with different thickness and still get good results.
These pumps work well with fluids that have solids because they do not wear out fast.
Piston pumps are used in many industries because they give control, power, and steady work. When you need a pump for hard jobs, a hydraulic piston pump gives strong and steady performance.
You can learn how a hydraulic piston pump works by looking at each step. The pump has a piston inside a cylinder that moves hydraulic fluid. First, the piston pulls away from the cylinder head. This makes a vacuum and pulls fluid into the cylinder through the inlet valve. Next, the piston pushes toward the cylinder head. This action forces the fluid out through the outlet valve. The pump keeps doing this again and again to move fluid with strong pressure.
Here are the steps in a simple way:
The piston moves back and makes room in the cylinder.
Hydraulic fluid comes in through the inlet valve.
The piston moves forward and squeezes the fluid.
The outlet valve opens, and the fluid goes out.
The pump repeats these steps to keep flow and pressure steady.
Tip: The pump gives you steady pressure because it repeats these steps. This is great for machines that need strong and steady force.
The piston and cylinder work together to make hydraulic pressure. You see the piston move inside the cylinder and push the fluid. The fluid cannot be squeezed, so it carries pressure very well. The pressure is different on each side of the piston. This difference pushes the piston and makes force for your equipment.
The pump makes pressure by pushing fluid into the cylinder.
Hydraulic fluid carries pressure because it cannot be squeezed.
The pressure difference moves the piston and makes force for your system.
You use a piston pump when you need to control fluid power exactly. The design helps you do hard jobs and keeps your machines working well. If you want to know how a hydraulic piston pump works, watch how the piston and cylinder work together to make strong and steady pressure for your hydraulic systems.
The piston and cylinder are the main parts of a hydraulic piston pump. The piston moves inside the cylinder. This movement pushes and pulls fluid. These parts are made from strong materials. Strong materials help them last longer and work well under pressure. Here is a table that shows what materials are used and why they are good:
Material | Durability (Years) | Key Properties |
|---|---|---|
Chrome-plated steel | 15+ | Great at resisting wear, protects against rust, hard surface, less friction |
Hardened Stainless Steel | 10-15 | Resists rust, strong but not heavy, handles heat well, needs little care |
Aluminum Alloys | 5-10 | Strong but light, handles heat well, costs less, easy to shape |
Pick the material that fits your job. Chrome-plated steel is best for tough work. Aluminum alloys are good if you want a lighter pump.
Valves and seals help control fluid and keep the pump tight. Valves let fluid in and out at the right time. Seals stop leaks and keep air and water out. Check these parts often to keep your pump working well. Most problems happen when air or water gets in, fluid levels are wrong, or mistakes are made during care. Here are some common problems and ways to stop them:
Air and water getting in: Use good seals and check fluid often.
Temperature issues: Keep the pump at the right temperature.
Fluid problems: Check and fill fluids when needed.
Mistakes by people: Train workers and follow care steps.
Tip: Checking your pump and using good seals helps it last longer and work better.
The housing holds all the pump parts together and keeps them safe. Inside the housing are bearings, shafts, and ports. New technology makes these parts stronger and better. Some pumps use new materials like polymers and composites. These materials last longer and need less care. Smart sensors can watch your pump and tell you if something is wrong. Some companies use recycled materials and green fluids to save energy and cut down on waste.
Advancement Type | Description | Benefits |
|---|---|---|
Advancements in Materials | New materials like polymers and composites make pumps last longer and work better. | Parts last longer, weigh less, handle heat better, and cost less to care for. |
Integration of Smart Technology | Smart sensors and tools help watch the pump and give data. | Fix problems fast, work better, and have less downtime. |
Sustainability Considerations | Using recycled materials and green fluids helps the planet and saves energy. | Saves up to 20% energy, cuts waste by about 30%, and costs less to run. |
These new features help your pump work better and break down less. When you choose a piston pump, look for these new things to help your system do its best.
You can pick from different hydraulic piston pumps. Each type is made for a special job or industry. Let’s see the main types and how they work.
Single-acting piston pumps move fluid one way. The piston pushes fluid out with hydraulic pressure. It goes back by a spring or gravity. Double-acting piston pumps move fluid both ways. They use hydraulic pressure for each stroke. Double-acting models can do more jobs.
Feature | Single Acting Piston Pump | Double Acting Piston Pump |
|---|---|---|
Operation | Moves in one direction using hydraulic pressure; returns via spring or gravity | Moves in two directions using hydraulic pressure |
Efficiency | Simple and cost-effective for repetitive tasks | More versatile, suitable for complex tasks |
Applications | Ideal for fabrication and low-cost systems | Used in industrial applications and robotics |
Single-acting pumps are good for easy, repeating jobs.
Double-acting pumps do harder jobs and work better.
Double-acting piston pumps are used in excavators and big machines. These pumps help you lift, dig, and move things with strong force both ways. You also find them in robots and factories where control is important.
Axial piston pumps have pistons lined up with the main shaft. This design gives smooth flow and less noise. Variable displacement axial piston pumps let you change flow rates. This saves energy and gives better control. These pumps are used in building machines and factory systems.
Radial piston pumps have pistons in a star shape around the shaft. These pumps give very high pressure and work well. They are used for metal shaping, deep-sea tools, and hydraulic presses.
Feature | Radial Piston Pump | Axial Piston Pump |
|---|---|---|
Piston Arrangement | Radially distributed (star shape) | Parallel to the main shaft |
Pressure Capacity | Ultra-high pressure (600-1000 bar) | Mainstream 200-450 bar, up to 600 bar |
