Hydraulic Power Packs : making their own hands

During the industrial tool, which requires high pressure, can not do without the use of hydraulic oil station.On the device, advantages and features of the production of oil station with their own hands will be discussed later.

device type hydraulic oil station

powerpack used to convert various types of energy into mechanical type of liquid.The hydraulic oil tank pumps the hydraulic fluid, and creates pressure in the working area of ​​executive devices.

hydraulic oil tank is characterized by:

1. hydraulic tank - it is made of black steel or stainless steel.The inner surface of the tank and passes sandblasting double coating polymer.If you expect continuous operation of oil station, the walls are placed inside the tank, which promote mixing and cooling liquid.The main functions of the hydraulic tank is:

• acting as a reservoir, in which the oil is located;
• cooling of the working fluid;
• feature coarse filter, which upheld pollution;
• separation of liquid water and oxygen;
• supply of the working fluid for the pumping equipment.

1. Pump.The pumps come in different types and different technical features.The feed rate of the liquid pump is 3 to 300 liters per minute.That varieties of pumps, which are used in hydraulic powerpack:

• pinion type;
• plate type;
• radially pluzhennogo type;
• axial piston type.

1. prime mover - in this case, the hydraulic.Its main function is to convert mechanical energy into rotational force or kinetic energy.
2. Pipeline, which is a channel system consisting of hoses with high pressure.Also in the pipeline includes metal pipes which have a modular installation or Butt.Their main function is to connect the hydraulic equipment with the regulators, power distributors.Responsible for the transfer of the working fluid and its timely return.
3. drain filter - it is responsible for cleaning the working fluid returning to the unit tank.
4. suction filter, which ensures the prevention of ingress of solid pieces of mechanical impurities into the pump pipe.Installation of the filter is made directly on the site of the tube under the working fluid.Since the suction pump has a limited capacity, the resistance of the filter towards the working liquid should be minimal.These filters produce a crude liquid purification and consist of several structural parts.Some filters have a capacity valve or a magnetic trap.
5. filler cap, which is an air filter - this item performs the function of preventing dirt from entering the hydraulic fluid at the opening of the tank.
6. measuring element: pressure gauge, oil quantity indicator.
7. distributor, which are:

• electro;
• hand, with one or more sections.

operating principle of the hydraulic oil station

Hydraulic Power Packs also called hydraulic drive, hydraulic unit or the hydraulic pump station.It appears in the form of the system, converts energy through control of hydraulic fluid.

type converts the energy is directly dependent on the design features of the prime mover, which is the main element of oil station.

operating principle of the hydraulic oil station is to transfer torque from the source of mechanical energy (electric motor or internal combustion engine) to the pump shaft.By means of the suction filter is sucked working fluid, in this case, an oil pump via.Then RJ transmitted through the pipeline system to a hydraulic equipment, which it distributes and determines the pressure on the way to the cylinder or hydraulic motor performing work.

The spent working fluid pipe system for passing flushing filters back into the hydraulic tank.

Key Applications Hydraulic Power Packs:

• Industry;
• metals;
• construction;
• energy;
• farm;
• transport.

The main types of hydraulic oil stations

Hydraulic oil station shared by several parameters.Depending on the type of movement, they are:

• cell type;
• stationary type;
• self-propelled type.

The first type is characterized by a compact and easy to transport.Mobile oil stations are low power and are used in the private sphere.

stationary devices used in industry.Such oil stations have large dimensions and operate at high power.

propelled Hydraulic Power Packs combine the advantages of the two previous types.They have a high power, and means for conveying, in particular - Wheels.

Depending on the prime mover, oil station is:

• hydraulic;
• electricity;
• air;
• gasoline;
• diesel.

greatest compactness different oil station on the basis of a gasoline engine.For pneumatic oil station requires the mandatory presence of the compressor, the minimum operating pressure of which is 0.5 MPa.Hydraulic oil station on the basis of an actuator used in enterprises, which impose stringent requirements for use, and in particular, in the factories of petrochemical or mining areas.Such oil stations have a long life and use devices that provide lubrication system by spraying the working fluid.

Depending on the type of valves, Hydraulic Power Packs are:

1. With the availability of manual handling crane - they pump and relieve the pressure in the hydraulic cylinder device.Used when working with equipment that has a spring return, such as tube bender or gaykorezy.
2. powerpack pumps with on-off valves is the pressure that can not only apply the oil to work, but also to ensure its return back to the system.Apply for equipment that has a two-position action.
3. devices with the presence of three-position distributor are the most popular.They allow you to work in the position of the stroke - retention and return.They are used for presses.

Under pressure oil stations are:

• weak pressure - up to 16 MPa;
• medium pressure - up to 45 MPa;
• oil station high pressure - up to 155 MPa;
• heavy duty pressure - more than 155 MPa.

Hydraulic Power Packs are different way to manage and are:

• manual type;
• electromagnetic type;
• automatic type.

In the first form of oil stations is controlled by a handle.The electromagnetic method of controlling involves pressing the push-button station, which is located on the oil station, or use the buttons on the remote control.

third type of control is a combination of the two previous methods.Office work is possible as a remote control and handle.

Depending on the type of hydraulic drive, oil station are:

• single stage;
• two-stage.

single-stage pump are single-threaded.These stations allow you to adjust the speed and mode of operation of the hydraulic cylinder.Maslostantsii of this type is used in cases where it is necessary to make the same effort to squeeze the molded body.For example, in the manufacture of briquettes from waste or garbage.They are also used in the manufacture of dry ice, gluing wood beams, pressing out and pressing in.

two-stage oil-pumping station consists of a two-stage cycle.They differ by the presence of double pump and Bulkhead Hydropanels.Such stations significantly save electricity.

Recommendations on the choice of hydraulic oil station

to buy Hydraulic Power Packs, contact a specialized company or directly to producers.

price of oil station depends on such factors:

• type of prime mover;
• pressure;
• power;
• type of distributor;
• ability to move;
• manufacturer.

When choosing oil station note the operating pressure, the working volume of the piston area, the speed and magnitude of the stroke, the drive type and configuration gidromaslostantsii.

The principal characteristics are:

• value performance or rated power;
• tank size for the fuel and hydraulic fluid pressure value.

Determining the type of oil station in accordance with the control method depends on the technical features of the enterprise or the direct functions of oil station.

Note that the value of the useful volume of the fuel tank must be more than a quarter of the total working volume of the hydraulic equipment to be used in conjunction with the oil station.Thus, another function of the oil tank is cooling and lubrication, however if it is no longer required volume, these functions are not performed.

To be able to operate simultaneously several tools should purchase a multi-way valve, port or multi-port pump.

When selecting hydraulic oil station type pay attention to its technical features and pre-read the instruction manual to determine the recommended supply of the working fluid, and compare it with the tool.If the supply is less, then there is a risk of slow operation of the equipment, in case of more supply - equipment fails.

hydraulic powerpack with their hands

Manufacturing hydraulic oil station - a very complex process.Therefore, in the absence of skills to work with this equipment, it is recommended to entrust this work to professionals.

To make Hydraulic Power Packs own hands requires:

• prime mover;
• hydraulic tank;
• filters: drain, suction;
• pump;
• system pipes;
• safety valve;
• distributors;
• gauge;
• oil level gauge.

Pay special attention to the selection of the hydraulic tank.Its size depends on the type of device that is connected to the oil station.Also note that the oil moving through the system, heated and returned to the tank heated, and hence a larger volume, and requires a space for heat dissipation.

hydraulic fluid absorption zones must have a partition that will improve the performance of oil station.

Do not use the oil viscosity is too high, if this action could not be avoided - add special additives.

Installing filters is mandatory - it will prolong the performance of oil stations and prevent its premature failure.

There are several ways to mount the hydraulic tank to the oil station design:

• horizontal mount, when the hydraulic equipment is mounted on top of the engine and is located on top of the lid, hydraulic tank must be rigid to prevent vibration of the engine;
• lower location of the hydraulic tank - this design is quite cumbersome and expensive, poor distribution of pressure requires more energy to increase cavitation;
• best option will be the location of the hydraulic tank vertically in relation to the entire plant, such equipment is compact and low shumoproizvoditelnostyu.

tank size depends on the amount of oil that is required to ensure the equipment efficiency, connected to the oil station.Depending on the form, the tanks are cylindrical or rectangular.
