DEVICE AND PRINCIPLE OF OPERATION OF THE HD65 HD 65 HD-65 37300-41700/37300-41701 GENERATOR
The device is shown on a photo. The case (5) and forward cover of the HD65 HD 65 HD-65 (2) generator serve as support for bearings (9 and 10) in which the anchor (4) rotates. On a winding of excitement of an anchor tension from the accumulator moves through brushes (7) and contact rings (11). The anchor is set in motion by means of a maple belt through a pulley (1). Prizapusk of the HD65 HD 65 HD-65 engine as soon as the anchor starts rotating, the electromagnetic field created by it induces alternating electric current in a winding of a stator (3). In the vypryamitelny block (6) this current becomes constant. Further current via the regulator of tension combined with the vypryamitelny block arrives in the car power supply network for food of system of ignition of HD65 HD 65 HD-65, lighting and the alarm system, instrumentations, etc. The storage battery will be connected to number of these devices and will start being recharged slightly later as soon as electric power, the vyrabatyvayemoygeneratorny HD65 HD 65 HD-65 3730041700/3730041701 installation, becomes enough to provide smooth functioning of all consumers.
WORKING CONDITIONS AND SOME RECOMMENDATIONS ABOUT HD-65 GENERATOR 37300-41700/37300-41701/3730041700/3730041701 HD65 HD 65 SERVICE
Conditions in which the generator 3730041700/3730041701 HD65 HD 65 HD-65 should work, in any way you won't call safe. On the HD65 HD 65 HD-65 37300-41700/37300-41701 generator get dirt, oil, moisture, the salt which harmful action is aggravated with high temperatures of air in podkapotny space. To minimize influence of salt "bathtubs", not to allow oxidation of output plugs генератора37300-41700/37300-41701/3730041700/3730041701 HD65 HD 65 HD-65 and loss for this reason in them reliable contact, it is recommended to keep fastenings of all generating wires under a layer of any jellied greasing. The special attention needs to be paid to a tension and timely replacement of a maple belt of the drive of the generator. It isn't necessary to allow even short operation of the generator 37300-41700/37300-41701 3730041700/3730041701 42623 HD65 HD 65 HD-65 with the disconnected storage battery. Splash in tension in the network, arising at accumulator shutdown, for example for generator check, is dangerous practically to all onboard electronic devices of modern cars. Check of operability of the HD65 HD 65 HD-65 37300-41700/37300-41701/3730041700/3730041701 generator on "spark" isn't allowed by short-term connection of the output plug with "mass" of the car also. In this case via the vypryamitelny block too high current which is capable to put diodes of the HD65 HD 65 HD-65 block of action proceeds.
MALFUNCTIONS OF THE HD65 HD 65 HD-65 GENERATOR
As it was spoken above, all generators are similar on a design. Therefore, main "diseases" of generators and ways of their "treatment" also will be approximately identical.
1 . The increased noise during the work. As a rule, wear or damage of bearings of an anchor of HD65 HD 65 HD-65 is the reason of noise. The first usually forward bearing fails: the big loadings falling on it, for example, because of an excessive tension of a driving HD65 HD 65 HD-65 belt affect. Usually replacement of bearings doesn't cause serious difficulties though for this purpose it is necessary to disassemble the HD65 HD 65 HD-65 37300-41700/37300-41701/3730041700/3730041701 generator completely almost. After dismantling it is necessary to pay attention to a condition of landing openings under bearings in the case and a forward cover of the HD65 HD 65 HD-65 37300-41700/37300-41701/3730041700/3730041701 generator. Seldom, but it happens that these openings are worn-out or deformed. If total wear in a landing opening and in the bearing appears more gap between an anchor and a stator, the anchor at rotation touches stator poles that is inadmissible. Replacement not only bearings, but also the case or a forward cover of the generator is required.
2 . The HD65 HD 65 HD-65 37300-41700/37300-41701/3730041700/3730041701 generator doesn't give charging current. The control lamp testifies to it on the dashboard, and also ampermeter or voltmeter indications if these devices equipped the car. If the belt of the HD65 HD 65 HD-65 37300-41700/37300-41701/3730041700/3730041701 generator is normally tense and doesn't slip, that a probable cause of malfunction — wear of brushes or their lag in the brush holder. Brushes not only wear out, but wear out also contact rings which are located on one shaft with an anchor and rotate together with it. It is clear that the more run, the is more and wear therefore very often service life of the HD65 HD 65 HD-65 37300-41700/37300-41701/3730041700/3730041701 generator is limited to durability of contact rings. Residual height of brushes has to be not less than 7 mm then brushes are subject to replacement. As brush spare parts often are on sale together with brush holders. At first it is necessary to take the brush holder with brushes, to unsolder wires of brushes from contact plates. It was necessary to replace worn-out details with the new. If violations in operation of the HD65 HD 65 HD-65 generator 37300-41700/37300-41701/3730041700/3730041701 42623 are connected with that brushes hardly move or in general lost mobility in brush holder nests because of hit of a dust, products of wear and other dirt, it is enough to take the brush holder and to wipe surfaces of its nests and a brush the pure napkin moistened in gasoline. Concerning wear and a podgoraniye of contact rings if this process didn't go too far, it is possible to be limited to cleaning of rings by a grinding skin. At big wear contact rings should be pierced and ground on the machine.
3 . Break or mezhvitkovy short circuits in anchor and stator windings. In this case the HD65 HD 65 HD-65 generator 37300-41700/37300-41701/3730041700/3730041701 42623 also won't develop current. Generally speaking, breaks and mezhvitkovy short circuits in a statorny winding and a winding of excitement of an anchor define by an ohmmeter, but sometimes breaks can be found after dismantling at external survey. The special attention should be paid to a condition of places of the soldering of conclusions of the coil of excitement to contact rings, connection of wires of brushes with contact plates, etc. In case of short circuit of windings, most likely, it is necessary to replace an anchor or a stator with the case assembled, and even the generator entirely.
4 . Failure of the vypryamitelny block. If the brush knot works normally, in electric chains and windings there are no breaks and short circuits, and the HD65 HD 65 HD-65 37300-41700/37300-41701/3730041700/3730041701 generator all the same doesn't develop charging current, responsible for malfunction, most likely, is the vypryamitelny HD65 HD 65 HD-65 block. Faulty diodes — basic elements of the vypryamitelny block — can or not pass at all current (in case of break), or to pass current in both directions (in case of short circuit). The refused vypryamitelny block is subject to replacement.
5 . Violations in operation of the regulator of tension of HD65 HD 65 HD-65. Defects in the regulator of tension are shown that the generator gives big charging current, and the accumulator is systematically recharged (electrolyte), or current, on the contrary, too weak "boils", and even in general is absent. By the way, violations in operation of the regulator of tension — one of the most widespread malfunctions in system of generating installation. Operation of the regulator can be checked on the car. It is necessary to allow to work to the engine of 15 minutes on average turns, then to include headlights and by means of the voltmeter of a direct current to measure tension between the output plug and "mass" of the HD65 HD 65 HD-65 generator. If the regulator is serviceable, the measured tension has to lie within 25,5-26,5 Century. Otherwise the regulator should be replaced.
