Buy a hydraulic pump

Hydraulic pump- the key element of the hydraulic system, which provides the transmission of the energy fluid energy. The correct choice of the pump determines the effectiveness and reliability of the entire system. In this leadership, we will consider the main typeshydraulic pumps, their characteristics, selection criteria and place where you can profitablyBuy a hydraulic pump.

What's happenedHydraulic pumpAnd why is it needed?

Hydraulic pumpconverts mechanical energy (for example, from the engine) into hydraulic energy, creating a flow of working fluid under pressure. This liquid is then used to actle hydraulic cylinders, motors and other executive mechanisms.

Hydraulic pumpswidely used in:

• Construction equipment (excavators, loaders, taps)
• Agricultural machinery (tractors, combines)
• Industrial equipment (presses, machines)
• Vehicles (brake systems, rudder of the steering wheel)

The main typeshydraulic pumps

There are several main typeshydraulic pumps, each of which has its own characteristics and advantages:

Gear pumps

These are the simplest and most commonHydraulic pumps. They consist of two gears in the hook. When gear rotates, the liquid is captured between the teeth and is transferred from the suction pipe to the discharge.

Advantages:

• Simplicity of design
• Low cost
• Unpretentity in operation

Flaws:

• Low efficiency (especially with high pressure)
• High noise level
• Short service life (compared with other types)

Plastic pumps

In these pumps, the working element is the plates installed in the rotor, which rotates inside the case. The plates are advanced and moved, changing the volume of the chambers and creating a fluid flow.

Advantages:

• Average effectiveness
• STRICE WORK THE SIGNESS PACS
• Higher efficiency than gear pumps

Flaws:

• A more complex design than gear pumps
• Sensitivity to pollution of the working fluid

Piston pumps

These are the most effective and powerfulHydraulic pumps. They use pistons that move in cylinders to create fluid flow. There are radial piston and axial piston pumps.

Advantages:

• High efficiency (up to 95%)
• High pressure
• Long service life

Flaws:

• Complex design
• High cost
• Demands on the purity of working fluid

How to chooseHydraulic pump: main criteria

When choosinghydraulic pumpThe following factors must be taken into account:

• Productivity (stream): The volume of liquid, which the pump pumps per unit of time (l/min or m3/h).
• Pressure: Maximum pressure that the pump can create (bar or MPa).
• Type of working fluid: The pump should be compatible with the working fluid used (mineral oil, synthetic oil, water-glycol mixture, etc.).
• The viscosity of the working fluid: Viscosity affects the performance and efficiency of the pump.
• The temperature of the working fluid: The pump should work in the temperature range acceptable for the liquid used and the pump materials.
• Type of drive: Electric, hydraulic, mechanical, etc.
• terms of Use: The pump should be resistant to environmental conditions (temperature, humidity, pollution).
• Price: It is necessary to take into account the cost of the pump, its installation and maintenance.

WhereBuy a hydraulic pump?

Buy a hydraulic pumpIt is possible in specialized stores of hydraulic equipment, at official dealers of manufacturers, as well as through online stores. When choosing a supplier, pay attention to the following factors:

• The reputation of the supplier: Customer reviews, market experience.
• Assortment of products: The presence of a wide selection of pumps of different types and manufacturers.
• Product quality: The availability of certificates of conformity and quality guarantees.
• Prices: Comparison of prices of different suppliers.
• Service: The availability of a service center, the possibility of repair and maintenance.
• Delivery: Conditions and terms of delivery.

Example: Choosing a pump for an excavator

Suppose you needBuy a hydraulic pumpFor an excavator. The following parameters must be taken into account:

• Productivity: is determined by the total stream of all hydraulic cylinders of the excavator.
• Pressure: must correspond to the maximum working pressure of the excavator hydraulic system.
• Pump type: Piston pump is the best choice for the excavator, as it provides high efficiency and pressure.

It is recommended to contact specialists to select a specific pump model corresponding to the parameters of your excavator.
