Hydraulic pump

Hydraulic pumpIt is a key component of the hydraulic system that converts mechanical energy into hydraulic energy of fluid under pressure. The right choicehydraulic pumpIt is crucial to ensure the effective and reliable operation of the equipment. In this article we will consider different typeshydraulic pumps, their characteristics, criteria for choosing and area of ​​application, as well as provide practical tips for maintenance and increase in service life.

Typeshydraulic pumps

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

• Gear pumps
• Plastic pumps
• Piston pumps

Gear pumps

Sixth pumps are one of the simplest and most common typeshydraulic pumps. They work, passing the liquid between the teeth of two rotating gears. They are distinguished by simplicity of design, reliability and relatively low cost. There are gear pumps with external and internal hook.

Advantages of gear pumps:

• Low cost
• Simple design
• Reliability

Disadvantages of gear pumps:

• Relatively low efficiency
• High noise level
• Sensitivity to pollution

Plastic pumps

Bad pumps use a rotor with slipping plates to pump fluid. They provide a smoother fluid supply than gear pumps, and have a higher efficiency. There are one -time and double action.

Advantages of lamellar pumps:

• Higher efficiency than gear pumps
• More quiet work
• Puffing fluid

Disadvantages of lamellar pumps:

• A more complex design than gear pumps
• Sensitivity to pollution
• Limited pressure

Piston pumps

Piston pumps are the most effective and expensivehydraulic pumps. They use pistons moving in cylinders to create pressure and pumping fluid. There are axial piston and radial piston pumps.

Advantages of piston pumps:

• High efficiency
• High pressure
• Adjustable feed

Disadvantages of piston pumps:

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

Choice criteriahydraulic pump

When choosinghydraulic pumpThe following factors must be taken into account:

• Required pressure and consumption
• Type of working fluid
• Operating conditions (temperature, pollution)
• Type of drive
• Budget

Consider each of these factors in more detail.

Required pressure and consumption

Pressure and consumption are two basic characteristicshydraulic pump. The pressure determines the force that the pump can generate, and the consumption - the volume of fluid that the pump can pump into a unit of time. It is necessary to choose a pump that will provide the required pressure and consumption for a specific task.

Type of working fluid

The type of working fluid is also an important factor. Different types of pumps are designed to work with different types of liquids. It is necessary to make sure that the selected pump is compatible with the working fluid used.

terms of Use

Operation conditions, such as temperature and pollution, can also affect the choice of the pump. For example, if the pump operates at high temperatures, you must choose a pump that can withstand such temperatures. If the pump will work in a contaminated environment, you need to choose a pump that is resistant to pollution, or install filters.

Type of drive

The type of drive determines how the pump will be driven. The most common types of drive are electric motors and internal combustion engines. It is necessary to select a pump compatible with the existing type of drive.

Budget

The budget is also an important factor. The cost of various types of pumps can vary greatly. It is necessary to choose a pump that corresponds to the budget and provides the required characteristics.

Areas of applicationhydraulic pumps

Hydraulic pumpsused in various fields, including:

• Construction equipment (excavators, loaders, taps)
• Agricultural equipment (tractors, combines)
• Industrial equipment (presses, machines)
• Automotive industry (steering amplifiers, brake systems)
• Aviation (flight control systems)

Service and increase in service lifehydraulic pump

Proper maintenance is crucial to increase the service lifehydraulic pump. Main recommendations:

• Regular replacement of working fluid
• Regular filter replacement
• Checking for leaks
• Compliance with recommended operating modes

Compliance with these simple recommendations will help to avoid the premature failure of the pump and extend its service life.
