Hydraulic Maslostation Device
Maslostation is used to convert various types of energy into a mechanical type fluid energy. Hydraulic oil suspension pumps hydraulic fluid and creates pressure in the working section of the actuators.
Hydraulic oil station is characterized by the presence:
- Hydraulic tank - It is made of black steel or stainless steel. The inner surface of the tank passes sandblasting and double coating by polymer. If there is an extensive operation of the oil station, then partitions are placed inside the tank, which contribute to stirring and cooling the fluid. The main functions of the hydraulic tank is:
- the role of the reservoir in which the oil is located;
- cooling of the working fluid;
- the function of a coarse filter in which contamination is upset;
- separation from water and oxygen liquid;
- supply of working fluid for pumping equipment.
- Pump. Pumps are different types and differ in technical features. The liquid feed rate of the pump is from 3 to 300 liters per minute. Here is a variety of pumps that are used in hydraulic oil stations:
- gear type;
- lamellar type;
- radial-polished type;
- axial piston type.
- Primary engine - in this case, hydraulic. The main function is the transformation of mechanical energy due to rotation or kinetic energy.
- Pipeline, which is a system of channels consisting of high pressure sleeves. Also, the pipeline includes metal pipes that are characterized by a modular or butt installation. The main function is to connect hydraulic equipment with regulators, energy distributors. Responsible for the transfer of working fluid and its timely return.
- A drain filter - it is responsible for cleaning the working fluid returning to the hydraulic panel device.
- A suction filter, which ensures the prevention of solid parts of the mechanical impurity into the pumping line. Installing this filter is made directly on the pipe section under the working fluid. Since the pump has limited suction capabilities, the resistance of filters on the path to the working fluid should be minimal. These filters produce coarse liquid cleaning and consist of several constructive parts. Some filters have a bandwidth or magnetic trap.
- The filling neck, in which the air filter is located - this element performs the function of preventing dirt from entering the working fluid during the opening of the tank.
- Measuring elements: Pressure gauge, oil number pointer.
- Dispensers who happen:
- electrohydraulic;
- manual, with one or more sections.
Principle of operation of the hydraulic oil plant
The hydraulic oil station is also called hydraulic drive, a hydraulic unit or a hydraulic pumping station. It appears in the form of a system that transforms energy through the control of hydraulic fluid.
The type of transformative energy directly depends on the design features of the primary engine, which is the main element of the oil plant.
The principle of operation of the hydraulic oil station consists in transmitting the torque from the original source of mechanical energy (electric motor or internal combustion engine) to the hydraulic pump shaft. With the help of the suction filter, the working fluid is absorbed, in this case, oils, using hydraulic pump. Then the RG is transmitted through the pipeline system to hydraulic instrument, which distributes it and determines its pressure on the way to the hydraulic cylinder or hydraulic material performing operation.
The spent working fluid on the pipe system, passing the drain filters, returns to the hydraulic tank.
Benefits and sphere of using hydraulic type oil suspension
If you compare the hydraulic oil station with a standard compressor, it is allocated to such advantages:

Hydraulic oil stations are used to pump and purify oil. They are able to serve oil into separate parts of the machinery, produce lubricant and cooling its elements. With the help of hydraulic oil stations, hydraulic cylinders, machinery, equipment and pipeline systems are test.
Main spheres of hydraulic oil stations:
- industrial;
- metallurgical;
- construction;
- energy;
- agricultural;
- transport.
Main types of hydraulic oil stations
Hydraulic oil stations are divided into several parameters. Depending on the type of movement, they happen:
- mobile type;
- stationary type;
- self-propelled type.
The first type is characterized by compact sizes and is easily transported. Mobile oil stations have low power and are used in the private sphere.
Stationary devices are used in industry. Such oil stations have large dimensions and operate at high power.
Self-propelled hydraulic oil stations connect the advantages of two previous species. They have both high power and means for transportation, and in particular - wheels.
Depending on the primary engine, the maslostation happens:
- hydraulic;
- electrical;
- pneumatic;
- gasoline;
- diesel.
Maslostations based on a gasoline engine differ in the greatest compactness. For the operation of a pneumatic oil plant, a compressor is required, the minimum working pressure of which is from 0.5 MPa. Hydraulic oil stations based on pneumatic actuator are applied in enterprises that make strict requirements for work, and in particular, in the factories of the petrochemical or mining direction. Such oil stations have a longer service life and use devices that provide lubrication of the system by spraying the working fluid.
Depending on the type of distributors, hydraulic oil stations are:
- With the presence of a manual discharge crane - they are injected and reset the pressure into the hydraulic cylinder device. Used when working with equipment, which has a spring return, such as tube bending or nut.
- Oil station with two-position dispensers pumps such a pressure that is capable of not only to supply oil to work, but also ensure its return back to the system. Apply for equipment that has a two-position effect.
- Devices with the presence of a three-position distributor are the most popular. They allow you to work in the position of the working stroke - hold and return. Used to work presses.
In accordance with pressure, oil stations are:
- weak pressure - up to 16 MPa;
- average pressure - up to 45 MPa;
- high pressure maslostation - up to 155 MPa;
- heavy duty pressure - more than 155 MPa.
Hydraulic Power Packs different way to manage and can be:
- manual type;
- electromagnetic type;
- automatic type.
In the first form of oil stations is controlled by a handle. The electromagnetic method of controlling the means pressing the push-button station, which is located on the oil station, or use the remote control on the buttons.
The third type of control is a combination of the two previous methods. operation control is possible as a remote control and handle.
Depending on the type of hydraulic drive, oil stations are:
- single stage;
- two-stage.
Single-stage, single-flow pump have. These stations allow you to adjust the speed and mode of operation of the hydraulic cylinder. Oil station of this type is used in cases where it is necessary to make the same effort to compress the molded body. For example, in the manufacture of briquettes from waste or garbage. they are also used in the production of dry ice, gluing wood beams, press-fitting or pressing out.
Two-stage, oil-pumping station consists of a two-step cycle. Characterized by having tandem pump and Hydropanels bulkhead. Such stations significantly save electricity.
Recommendations regarding the selection of the hydraulic oil station
Hydraulic Power Packs to buy, contact a specialized company or directly to producers.
The price of oil station depends on such factors:
- type of prime mover;
- pressure;
- power;
- type of distributor;
- movable;
- manufacturer.
When choosing oil stations note the operating pressure, the working volume of the piston portion, the speed and magnitude of the stroke, the drive type and configuration gidromaslostantsii.
The main features include:
- performance value or nominal power;
- fuel tank size and importance of the working fluid pressure.
Determining the type of oil station in accordance with the control method depends on the technical features of the enterprise or direct functions oil station.
Note that the fuel tank the quantity of useful volume should be larger for a quarter of the total displacement volume of the hydraulic equipment to be used in combination with the oil station. At the same time, another function of the oil tank is to lubricate and cool, so if it is not more than the required volume, these functions will not be performed.
To be able to simultaneous operation of multiple tools, you must purchase a multi-way valve, port or multiport pump.
When choosing a hydraulic type oil plant, pay attention to its technical features and first read the instruction manual to determine the recommended supply of the working fluid and compare it with the tool. If the feed is less, then the risk of slow equipment is possible, in the event of a greater supply, the equipment fails.
Maslostania hydraulic with their own hands
The manufacture of hydraulic oil suspension is 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 a hydraulic oil station with their own hands requires:
- primary engine;
- hydraulic tank;
- filters: drain, suction;
- pump;
- pipe systems;
- safety valve;
- distributors;
- pressure gauge;
- oil level meter.
Special attention is paid to the choice of hydraulic tank. Its size depends on the type of device, which is connected to the maslostation. It should also be taken into account that the oil, moving through the system, heats up and returns to the tank heated, and therefore, in an enlarged volume, and requires space for heat dissipation.
The hydraulic fluid absorption zones must have partitions that will improve the performance of the oil plant.
Do not use too high viscosity oil if this action could not be avoided - add special additives.
Installation of filters is mandatory - they will prolong the operational characteristics of the oil plant and prevent its premature breakdown.
There are several methods for fastening the hydraulic tank to the construction of the oil suite:
- horizontal mount when hydraulic instrument is attached from above and the engine is located on top on the lid, the hydraulic tank must be tough to prevent engine vibration;
- the lower location of the hydraulic tank is a pretty bulky and expensive design, the improper distribution of pressure requires additional energy to increase cavitation;
- the best option will be the location of the hydraulic tank vertically with respect to the entire station, such equipment is distinguished by compactness and low noise effect.
The tank size depends on the amount of oil, which is required to ensure the performance of the equipment connected to the oil suslation. Depending on the shape, the tanks are cylindrical or rectangular.
