Waterjet cutting intensifier pump

Waterjet cutting intensifier pump

There are two types of pumps used today in waterjet cutting: the hydraulic intensifier pump and the direct drive pump. Today, both intensifiers pump and direct drive pumps are capable of reliably delivering ultrahigh-pressure water, and both are successfully used in industry.

In this article, We discover what waterjet direct drives pump differently in design, performance, and even maintenance uncovering both their strengths and maintenance.

Strengths

Electric energy is directly converted into mechanical energy, reducing energy loss

The main motor is only started during cutting, saving power

The Servo motor can drill holes under low pressure and cut under high pressure

Three-cylinder design, stable output pressure, pressure drop within 1Mpa during reversing

Under the same pressure, the cutting speed is 10% to 20% higher than the hydraulic pump

The continuous and stable output of high-pressure water, high cutting efficiency, all-weather operation

Both torque mode and speed mode are available, torque mode is used for constant pressure cutting, speed mode is used for maintenance, and has a low-pressure alarm function.

Direct drive pump has a simple structure, low failure rate, and easy troubleshooting

Direct drive pump does not require a cooling system

Maintenance

Replace the hydraulic oil and clean the oil tank once every six months.

Clean the air filter while cleaning the oil tank.

Regularly check the signal light of the oil filter. Once the signal light is on, clean the oil filter immediately.

Check frequently (oil temperature is ≥ 45 ℃) whether the cooling device starts automatically (cooling water temperature <30 ℃).

Always observe the liquid condition. When the liquid level is close to the lower limit, please add the recommended hydraulic oil to the oil tank in time.

Fill the lubricating points of the mechanical transmission part of the equipment with oil as required.

Regularly check the dust prevention devices at all places, and timely deal with any damage or loose connection found to prevent sand and dust from entering and damaging the equipment.

Usually, the direct drive pump is used in the waterjet cutting industry. Direct drive pump structure is simple, to help you save power.
