Abstract

The utility model discloses a testing device of a large-sized diesel generator. Two bearing bush seats are fixedly mounted on a base; one extending end of a rotary shaft of a rotor of the diesel generator is directly mounted on one bearing bush seat; the other extending end of the rotary shaft is connected with a false shaft coupler; the other end of the false shaft coupler is connected with one end of a false shaft mounted on the other bearing bush seat; and the other end of the false shaft is connected with an output shaft of a prime motor by the aid of a coupler. The testing device uses a motor to replace a huge diesel engine to serve as the prime motor for testing, simulates the working environment of the diesel generator by the aid of the false shaft and the coupler, and can test various parameters of the diesel generator on a modification site or a production site of the diesel generator, thereby effectively solving the problem that a diesel generator can be tested only after being mounted on site.

Description

A kind of test unit of large-sized diesel generator
Technical field
The utility model patent relates to the experimental provision of large-sized diesel generator.
Background technology
The renovation technique of large-sized diesel generator belongs to a kind of innovative technology in the motor reconstruct market at home, and improved diesel-driven generator is mainly sold to middle-eastern crude and produced abundant area.The vast market space is arranged.The problem that occurs in this type of motor reconstruct process is quite a lot of, and wherein distinct issues appear at the test of diesel-driven generator the most.Diesel-driven generator for the effect of confirming to transform, must be done type approval test to diesel-driven generator after transformation is finished.At present, after waiting diesel-driven generator to transport to the scene often to install, utilize on-the-spot already installed diesel engine diesel-driven generator to be carried out the test of every performance again, if diesel-driven generator the test mass problem occurs in the working site or the diesel-driven generator operating index does not reach requirement, then its maintenance cost is quite expensive.
The utility model content
The purpose of this utility model is to overcome currently can't carry out the defective of type experiment and the test unit of a kind of large-sized diesel generator of providing to improved large-sized diesel generator.
The purpose of this utility model is achieved by following technical proposals: two bush seat are fixed on the base, the external part of diesel-driven generator rotor shaft is directly installed on the bush seat, the external part of the rotating shaft other end is connected with an end of dummy shaft shaft coupling, the other end of dummy shaft shaft coupling is connected with dummy shaft one end on being installed in another bush seat, and the dummy shaft other end links to each other with the output shaft of prime mover by shaft coupling again.
Be provided with the dummy shaft coupler protective casing in the outside of dummy shaft shaft coupling.
Be provided with coupler protective casing in the shaft coupling outside.
Axial float when preventing rotor operation is provided with rotor limit device in the junction of other end rotating shaft and dummy shaft shaft coupling one end.
Technique effect of the present utility model is: owing to utilize motor to replace huge diesel engine to be used as experiment prime mover, and by design and making base, dummy shaft and shaft coupling, simulate the working environment of diesel-driven generator, therefore, transformation ground or grown place at diesel-driven generator just can be tested the parameters of diesel-driven generator, thereby can solve the confidential situation that is installed to on-the-spot back aptitude test of diesel generation effectively.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing:
Referring to Fig. 1,
Two bush seat 2 are fixed on the base 1, the external part of diesel generation machine rotor 3 rotating shafts 11 1 ends is directly installed on the bush seat 2, the external part of rotating shaft 11 other ends is connected with an end of dummy shaft shaft coupling 5, the other end of dummy shaft shaft coupling 5 is connected with dummy shaft 6 one ends on being installed in another bush seat, and dummy shaft 6 other ends link to each other with the output shaft of prime mover 9 by shaft coupling 8 again.
Running safety in order to test has been set up dummy shaft coupler protective casing 4 in dummy shaft shaft coupling 5 outsides, has set up coupler protective casing 7 in the outside of shaft coupling 8.
Axial float when preventing rotor operation has rotor limit device 10 on the connecting flange both sides of rotating shaft 11 and dummy shaft 6.
