Electro Max Electric Tensioning Pump

Hydraulic pumps in tensioning applications typically run intermittently, engaging when tensioning is required and disengaging when the desired tension is achieved. This controlled operation conserves energy and enhances pump longevity.

Hydraulic tensioning focuses on applying tension to bolts, ensuring even and controlled clamping force. Torquing, on the other hand, involves tightening bolts by applying rotational force. Tensioning is preferred for critical joints requiring precise and uniform force distribution.

Hydraulic tensioning is a method of tightening bolts by using hydraulic force to stretch the bolt, ensuring even and controlled tension. It is crucial for applications where precise and uniform clamping force is essential.

An electric hydraulic pump works by using an electric motor to power a pump that pressurizes hydraulic fluid (usually oil) within a closed hydraulic system. Here's how it operates- Electric Motor Activation: When the electric motor is powered on, it starts to rotate the pump shaft. Fluid Movement- The rotation of the shaft inside the pump creates suction, drawing hydraulic fluid from the reservoir and forcing it into the pump’s discharge port. Pressure Generation- As the fluid is forced through the pump, it is pressurized. This high-pressure fluid is then sent through hydraulic hoses to power cylinders, motors, or other hydraulic actuators within the system. Flow Control- The amount of flow and pressure can be regulated using control valves, ensuring that the correct amount of hydraulic force is delivered for the specific application.

The weight a 12V hydraulic pump can lift depends on several factors, including the pump’s pressure output, the type of hydraulic cylinder used, and the efficiency of the system. However, in general- A typical 12V hydraulic pump can generate pressures ranging from 1,500 psi to 3,000 psi (pounds per square inch). The lifting capacity also depends on the size of the hydraulic cylinder and its bore size.

The three main types of hydraulic pumps are- Gear Pumps- These are the most common and cost-effective hydraulic pumps. They use two interlocking gears to push hydraulic fluid through the system. Gear pumps provide a steady flow of fluid and are reliable in low-pressure applications. Vane Pumps- Vane pumps use a set of vanes that slide in and out of a rotor, creating suction and pressure to move hydraulic fluid. They are generally used in mid-range pressure systems and offer smoother flow compared to gear pumps. Piston Pumps- These pumps use pistons that move back and forth inside cylinders to pressurize hydraulic fluid. Piston pumps are suitable for high-pressure applications and are often used in heavy-duty machinery due to their efficiency and ability to handle high fluid volumes.

The working principle of a hydraulic pump is based on converting mechanical energy into fluid energy to generate hydraulic pressure. Here's the basic operation- Fluid Suction- The pump creates a low-pressure area inside the pump chamber, which draws hydraulic fluid from the reservoir. Fluid Compression- As the pump operates, mechanical energy is applied to move the fluid from the suction side to the discharge side. This movement compresses the fluid, increasing its pressure. Fluid Discharge- The pressurized fluid is then directed out of the pump and into the hydraulic system, where it is used to perform work such as lifting, clamping, or driving hydraulic motors and cylinders. Pressure Regulation- The pressure can be regulated using a pressure relief valve, which ensures that the system operates within safe limits.
