Description

[0001] POWER BALANCING UNIT

[0002] The invention refers to a power balancing unit designed to be used for powering producers that need to consume a very big spining moment and, implicitly, a high energy consumption. The producer can be an installation, or an equipment such as a breaking machine, a transport installation, a high capacity band carrier, a pump, a electrical power generator etc., which need to be driven by a carrying group in order to perform an operation such as stone crushing, material transport, absorbtion and repression of liquid, electrical power producing. The carrying group is provided with a high power carrying engine of several hundreds of kW supplied mostly with electricity or a diesel engine, or a fuel engine.

[0003] Curently, the increasing of the production capacities of the producers determines the use of some high power carrying groups. It is known that the carrying group is an aggregate consisting of an electrical engine, a diesel engine or a fuel based engine, mounted on a frame or a pedestal and having in all cases adequate couplings in order to transmit the moment of torsion generated when starting the carrying group to the producer.

[0004] The disadvantages of the carrying aggregates already known are the following:

[0005] - high energy consumption generate pollution which means they are sources for pollution with different substances and also high level sound pollution sources, because they use carrying groups of high power

[0006] The technical problem aimed to be solved by the invention is to create a power ballancing unit that reduces the energy consumption necesary to drive the producers and also to reduce the noxa agents and sound pollution.

[0007] According to the invention, the power ballancing unit solves these problems by the fact that it generates torsion and mass moment that added to the torsion moment generated by the carrying group ensures the functionality of the producer. In this way the power deficit of the producer is compensated, more precisely, there is a compensation of the torsion moment generated by the carrrying group in order to ensure the neccesary torsion moment needed for the producer to work. By adding the torsion mass moment generated by the mechanical power ballancing unit to the torsion moment generated by the carrying group it results a compensation of the torsion moment, respectively a compensation of the power between the installed power of the carrying group and the neccesary power for the producer to work.

[0008] Practically, a mechanical unit is placed between the carrying group and the producer and this unit is a torsion mass moment generator. The torsion mass moment is, in fact, generated by a wheel type piece set in rotation motion by the carrying group without using any other energy sources. The torsion mass moment is added to the torsion moment generated by the carrying group and it is transmited to the producer. Logically, the wheel type piece is designed so that to be able to compensate the difference between the torsion moment neccesary for the pproducer to work and the torsion moment generated by the carrrying group. When starting the engine of the carrying group, the driving axel of the wheel type piece that is connected with the carrying group determines the setting in rotation motion of the wheel type piece.

[0009] According to the invention, the power ballancing unit has the following advantages: -significantly reduces the energy consumptions

[0010] -reduces pollution with substances and sound pollution, becoming a 100% green equipment -reduces the maintenance costs, ensuring the increase of the investment efficiency.

[0011] Furthermore, we present a practical example of the power balancing unit as claimed related with figures number 1, 2a, 2b, 2c, 3, 4, 5, 6a, 6b, 6c, 7a, 7b, 7c, which represent:

[0025] In order to set in motion an electrical generator at a rotation of 1450 rot / min, which is currently driven by a diesel engine with a capacity of 2000 HP equivalent to 1470 kW, the torsion moment Mt generated for functioning:

[0026] Mt= 98743 [Nm]

[0027] The invention intends to use a carrying group with a power of 75 kW, with a rotation of 1450 rot / min which represents 1395 kW less than necessary. By using this power balancing unit the necessary torsion moment for the generator to work using a carrying group equipped with an electrical engine of maximum 75 kW at a functioning rotation of 1450 rot / min, can be produced and it generates a torsion moment equal to:

[0028] 97400»75 1450

[0029] Mt= 5038 [Nm]

[0030] By using the invention’s concept the torsion moment difference of 93705 Nm is ensured by the setting in motion of the mechanical unit with the wheel type revolution body 1 into rotation, being placed between the carrying group A and the producer C, considering that the mechanical unit is in fact the torsion mass moment generator.

[0031] Considering M the mass of the wheel type revolution body 1 concentrated in the center of mass of the section that is rotating, the center of mass being positioned at the distance RG = 0,5 m from the rotation axel and moving on a circular path with the tangent speed V. Considering the rotation of the carrying group to be 1450 rot / min it results:

[0032] V = 75,88 [m / s]

[0033] By a convenient arrangement of the elements in the Joule definition we can define and calculate 1 W (Watt) as a power unit, as follows: respectively: relation that can be also written as: 1 = UV * — (6) is In other words the power is equal to the product between mass and moving speed of the mass. According to the above example having a deficit of 1395 kW=l 395000 W, from relation (6) we can calculate the necessary mass of the wheel type piece in the pre-established conditions, respectively the mass should be concentrated in the center of mass of the section that is rotating and this center is positioned at a distance RG = 0,5 m from the rotation axel of the piece

[0034] - , 1395000

[0035] M= - = 18384 [N] sau

[0036] 75.88

[0037] M= 1838 kg

[0038] This is the mass of the wheel type piece 1 which generates a power of 1395 kW if the requested conditions are fullfiled. This power added to the power of the carrying group generates the increase of the driven capacity of the carrying group. According to the invention, this surplus of power generates the torsion moment difference necessary to ensure the working of the generator: 1450

[0039] Aft= 95705 [Nm]

[0040] So, the energy generated, according to the invention ensures the driving capacity of the carrying group to set in motion producers that need a significantly higher power than the carrying group if it was not used this unit, according to the invention.

[0041] The power balancing unit consists of a transfer box 6 of torsion mass moment mounted between a carrying group A and a producer C (Fig.2a, 2b, 2c).

[0042] The torsion mass moment generator B, in fact the power balancing unit, fulfils the aim of the invention due to its construction and realizes a balancing driving power. The torsion mass moment generator B consists (Fig.3) of a wheel type rotation body 1 set in rotation motion, mounted on an axle 2 which is coupled both to the carrying group A and to the producer C . The axle 2 is supported by two rollers, a one leading roller 3 and one leaded roller 4. The power balancing unit B is also provided with a protection 5 having the role to protect against accidents during the rotation mouvment of the wheel type rotation body 1.

[0043] The wheel type rotation body 1 is set in rotation motion in order to generate the torsion mass moment needed to suppliment the torsion moment generated by the carrying group A; according. to the neccessary supliment torsion moment, the wheel type rotation body 1 is designed to corespond the suply needs of the torsion moment neccessary for the producer A to work. (Fig.

[0044] 4)

[0045] The mass of the totaling body 1, concentrated in the gyration centre, compared to the rotation axle at a distance Rg ( gyration radius) generates the torsion moment. (Fig.l)

[0046] It is obvious that the producer C receives the torsion moment (gyration) from the carrying group A through the torsion mass moment generator B so that the producer C reaches the torsion moment generated by the carrying group A to which the torsion mass moment generated by the mouving wheel type rotation body 1 is added.

[0047] The axle 2 that supports the wheel type rotation body 1 is provided with some bearings 7 for the rollers 3 and 4 on which they stay; after the final processing, it is assembled with the wheel type rotation body 1 and they are compulsory dynamically balanced together (Fig.5).

[0048] The leading roller 3 has the role to secure the axle 2 against radial and axial mouvements (Fig.6a, 6b, 6c).

[0049] The leaded roller 4 has the role to secure the axle 2 against radial mouvements and to secure against any thermical deformations that may occure during the function. (Fig.7a, 7b, 7c).
