What is the reason for large oil spill on vertical turbine generator?

Introduction What is the reason for large oil spill on vertical turbine generator? If only the oil spill pipe is full of oil and there is no small oil leak in the upper guide oil seal, it should not matter if the seal oil also leaks oil,

What is the reason for large oil spill on vertical turbine generator?

If only the oil spill pipe is filled with oil and there is no small oil leak in the upper guide oil seal, it should not matter . If the oil seal is also leaking oil, a self-check is necessary:

1 Oil level

2 Oil seal design

3 Whether there is an oil leak in the inner oil pipe

3.1 Whether there is negative pressure in the inner oil pipe

3.2 Inner oil pipe Is the height of the oil pipe reasonable?

3.3 Is there a breathing pump phenomenon between the inner gear oil pipe and the main shaft due to the roundness of the gear oil?

4 Is there a possibility of oil creep in the upper gear oil seal

4.1 The spacing is too small

4.2 The step design is unreasonable

4.3 The splash-proof design is unreasonable

4.4 Failureseal

< p>4.5 Air seal failure

5 There is no air pressure balancing device in the oil chamber

I hope the above is helpful to you.

Typically there are coils wound on the stator; the rotor is installed and fixed on the base via bearings or bushings. There are silicon steel sheets on the rotor. The rotor of the DC motor will also be wound. with coils. When they all work In this state, the current will generate a magnetic field on the silicon steel sheets of the stator and rotor under the action of the coil, and the magnetic field will drive the rotor to rotate.

The stator of an asynchronous motor is composed of the stator core, the stator windings and the frame

1 Stator core

The function of the core of the stator is. serve as the motor magnet for the circuit and the built-in stator windings. The stator core is made of steel sheetsr silicon 0.5 mm thick. Both sides of the brick steel sheets are coated with insulating paint to insulate the sheets from each other to reduce core loss caused by the rotating magnetic field in the stator core. There are several identical slots drilled into the inner circle of the stator core to integrate the stator windings.

2. Stator Winding

The stator winding is the part of the motor circuit. Its main function is to pass current and generate induced potential to achieve electromechanical energy conversion. The stator winding coils are divided into single-layer and double-layer distribution in the stator location. In order to achieve better electromagnetic performance, ABB medium and large asynchronous motors use short-pitch double-layer windings.

3. Stator base

The main function of the base ist to fix and support the stator core, it must therefore have sufficient mechanical strength and rigidity to withstand operation or transport. of the motor. Medium and small AC motors generally use cast iron frames. For larger capacity AC motors, welded frames made of sheet steel are generally used.

The rotor of an asynchronous motor is composed of a rotor core, a rotor winding and a rotating shaft.

1. Rotor core

The rotor core is part of the magnetic circuit of the motor. Together with the stator core and the air gap, it forms the entire magnetic circuit of the motor. The rotor core is generally made of 0.5mm thick silicon steel sheets. Most of the rotor cores of medium and small AC motors are directly installed on the motor shaft. The rotor core of large neck motorsreciprocating rant isIt is installed on the rotating bracket and the bracket is sleeved on the rotating shaft.

2. Rotor Winding The function of the rotor winding is to induce electric potential, cause current to flow, and generate electromagnetic torque. Its structural forms include squirrel cage type and wire wrap type.

1. Squirrel Cage Rotor

The squirrel cage rotor winding is a self-closing winding. A guide bar is inserted into each rotating slot. At the slots protruding from the two ends of the iron core, two end rings respectively connect the two ends of all the guide bars. A6 If the iron core is removed, the shape of the entire winding looks like a "round cage", so it is called a squirrel cage rotor.

2. Wound rotor

The wound rotor is similar to the fixed winding. This is a symmetrical windingthree-phase circuit with insulated wires embedded in the slot of the rotor core and connected to form a star. Then connect the three small ends of the wire to the three slip rings on the shaft, then draw current out through the brushes. The characteristic of the wound rotor is that external resistors can be connected to the rotor winding circuit through slip rings and brushes to improve the motor starting performance or adjust the motor speed. In order to reduce brush wear, the wound asynchronous motor is sometimes equipped with a brush lifting short-circuit device, so that when the motor starts and there is no need to adjust the speed, the brushes are raised and all three slip rings are short-circuited at the same time.
