(54) CENTRIFUGE FOR LIQUID CLEANING

I

The invention relates to engine-building and relates, in particular, to full-speed centrifuges for cleaning liquids, mainly lubricating oil, as well as fuel from mechanical applications and other contaminants.

A known full-flow center 11fug for cleaning fluid, containing a rotor, inside of which is an insert for dividing the combustible fluid into two streams, directed to the cleaning and to the drive with oil intake wells | s /,

The indicated centrifuge is 11 closer to the proposed centrifuge by its technical essence and the result achieved.

The disadvantage of it is the low efficiency of the cleaning process due to the large non-uniform flow.

The goal of this is to increase the efficiency of the cleaning process.

This is achieved by the fact that in the centrifuge proposed, the forming inserts

performed on the curve, okskshaemy expression

X f,

where 2a is the pterbo axis

ly,

2b is the imaginary axis of the hyperbola, determined from the equation

B. where 2c is the focal distance,

and the inlets of the oil sump wells are located in the upper part of the insert.

For the main sizes of centrifuges for oil cleaning, the parameters a, b, c vary within the following limits: aa 2 O-3; from 4-7; B 20.4-30.6.

FIG. 1 shows the described centrifuge in section, of a general view; in fig. 2 is a scheme for constructing a curved-linear surface of inserts for centrifuges for cleaning a liquid, in which 363 is the diameter of the inner wall of the rotor dp i 13О-14О mm (the most widespread) for the specified range of variation of the parameters a, b, c, the centrifuge contains a rotor, - one of the interconnected screws. mi cylindrical cup 1 and cover 2. The rotor is fixed on the scr 3, having openings 4 and 5, respectively, for the water of crude oil into the cavity of the pry-gsa and drainage of the cleaned masp. The inside of the rotor on the lid 2 is reinforced with an insert 6, which is formed according to k; -, howl, described by the specified expression, and representing the palabry branch of the hyperbola. Insert 6 separates the rotor into two half-rows: preliminary cavity A and cleaning cavity B. The rotor assembly consists of 7 centners of oil suction tanks KD "co-operating with them. podtsev.8, equipped with filters 9 Centrifuge operates in the following way. Oil under pressure through the holes 4 in axis 3 enters the cavity A of the rotor where part of the flow C 4 10%) is sucked from the oil intake wells S to the nozzles 7 of the drive, the oil that reaches the cavity B is cleaned and passes from bottom to top inside the rotor along the insert 6 to the holes S in axis 3, with solid particles s 1 eulyutae greater than oil yielding weight, under the action of centrifugal forces I reject -: - to the periphery and keeping it on the inside wall of the rotor. For cleaning with a centrifuge, the rotor paa6iJpaeTcs5s for which a cylindrical cup is designed; from the cover, the walls are removed from the infrared; CLEANING PRODUCTS. The presence of a curvature insert of the proposed form lengthens the cleaning path inside the rotor while simultaneously removing the flow from the axis of rotation, improves the uniformity and symmetry of the cleaning boom due to the suction of part of the flow from under the narrower curvature of the curvilinear insert surface ). Consequently, the oil purification coefficient increases, as well as the service life of the internal combustion burner, the life of the device filled with cleaning products increases (their more uniform layer is reached, and, consequently, the greater capacity), the service life between disassemblies is increased, time and costs are reduced “I have found a centrifuge for cleaning a liquid, which is beneficial to engine oil in an internal combustion engine, containing a rotor, inside which is an insert for two tons of cleaned liquid to be cleaned t-eye, sent to the cleaning and to the drive with oil suction wells, so that, in order to increase the efficiency of the cleaning process, the insert forming is executed according to the curve described by the expression of hert 2a ™ and the axis of the hyperbola , 2b is the imaginary axis of the hyperbola, defined by the Z3 equation b: a, where 2c is the focal distance, and the openings of the oil intakes of the drive are located in the upper part of the insert, HcTonjrmxH information, taken during internal examination: 1 USSR author's certificate 205434, cl.
