1, electric drive
DC drive, AC / DC drive and AC / DC (AC) drive. Dongfeng, Dongfeng 2 and Dongfeng 3 locomotives are DC drive locomotives; Electric drive diesel locomotive developed after Dongfeng 4, All of them are AC and DC electric drive locomotives
since 1999, some AC drive locomotives have appeared in succession
the more successful ones are Dongfeng 4dj made in Dalian and Dongfeng 8CJ made in Qishuyan
the domestic electric drive locomotives are all named Dongfeng * type, while the imported ones are nd * type
the most famous ones in China are Dongfeng 11g and Dongfeng 8b made by Qishuyan Locomotive and rolling stock works < br />
2. Hydraulic transmission
General (mechanical reversing) hydraulic transmission and hydraulic transmission with hydraulic reversing; Another is hydraulic mechanical transmission. Beijing type and Dongfanghong series locomotives are hydraulic transmission locomotives; Most GK series instrial and mining locomotives are hydraulic reversing locomotives< The domestic hydraulic transmission is generally Dongfanghong * type and Beijing * type, and the GK series of instrial and mining locomotives are NY * type
the most famous hydraulic transmission locomotive in China is the ND5 type of American General Electric Company
3. Mechanical transmission
should be rare in China; It is rarely used in small power local railways and instrial and mining locomotives.
the main diesel locomotives in China are mainly electric driven Dongfeng locomotives.
now there are fewer hydraulic drive locomotives. However, in the past, the chief special trains were all electric driven internal combustion locomotives driven by ny6 and NY7 of Hansel factory in Germany, Only one Dongfeng 11z locomotive manufactured by Qishuyan Locomotive and rolling stock works is used for traction of special train
the function of transmission device of diesel locomotive
when the fuel supply per cycle is fixed, the torque of diesel engine changes little with the speed; The power of diesel engine is approximately proportional to the speed, and it can reach the rated power only at the rated speed. In order to make full use of the power of diesel engine and realize the requirements of locomotive traction characteristics, diesel locomotive must be equipped with transmission device, which is the intermediate link between diesel engine crankshaft and locomotive moving shaft. The torque, power speed characteristics of diesel engine are converted into the traction characteristics of diesel locomotive: that is, the locomotive has greater traction when starting and low-speed traction; After the train starts, when the handle of the main controller of the locomotive is at a given position, the speed and power of the diesel engine are fixed, and the train running resistance is less than the traction force of the locomotive (the acceleration force is positive), the speed of the locomotive increases along the traction characteristic curve (the traction force decreases accordingly); When the train resistance is greater than the locomotive traction force (the acceleration force is negative), the locomotive speed decreases along the traction characteristic curve (the traction force increases with it); At the same time, through the transmission device to achieve locomotive reversing, power braking and other conditions conversion function, to meet the requirements of train traction.
The diesel locomotives proced by Beijing Erqi Locomotive Works include: Dongfeng 7, Dongfeng 7b, Dongfeng 7C series, Dongfeng 7d series trunk line passenger and freight locomotives, Dongfeng 7e heavy haul shunting locomotives, Dongfeng 7F high power shunting locomotives, ck1e31 mining locomotives, gkd1e mining locomotives, GK3E mining locomotives Ck1e instrial and mining locomotive and Beijing series hydraulic diesel locomotive. Since 1975, the factory has proced more than 1800 diesel locomotives of Beijing type, Dongfeng 7 type and instrial and mining series, distributed in more than 70 locomotive depots of 14 railway bureaus and more than 40 large instrial and mining enterprises in petrochemical, coal, metallurgy, electric power and other instries, accounting for more than half of the national shunting locomotive market share. In 2003, the factory began to sell diesel locomotives to Vietnam and other countries and Taiwan
by the end of 2004, the Ministry of Railways has forced the diesel locomotives out of trunk line operation.
diesel locomotives
domestic diesel locomotives are installed by transmission There are three kinds of
transmission devices named after
1, electric drive
DC drive, AC / DC drive and AC / DC / AC drive. Dongfeng, Dongfeng 2 and Dongfeng 3 locomotives are DC drive locomotives; Electric drive diesel locomotive developed after Dongfeng 4, All of them are AC and DC electric drive locomotives
since 1999, some AC drive locomotives have appeared in succession
the more successful ones are Dongfeng 4dj made in Dalian and Dongfeng 8CJ made in Qishuyan
the domestic electric drive locomotives are all named Dongfeng * type, while the imported ones are nd * type
the most famous ones in China are Dongfeng 11g and Dongfeng 8b made by Qishuyan Locomotive and rolling stock works < br />2. Hydraulic transmission
General (mechanical reversing) hydraulic transmission and hydraulic transmission with hydraulic reversing; Another is hydraulic mechanical transmission. Beijing type and Dongfanghong series locomotives are hydraulic transmission locomotives; Most GK series instrial and mining locomotives are hydraulic reversing locomotives
domestic hydraulic transmission locomotives are generally Dongfanghong * type and Beijing * type, as well as instrial and mining locomotives GK series, while imported ones are NY * type
the most famous hydraulic transmission locomotives in China are the ND5 type of American General Electric Company
3 Mechanical transmission
should be very rare in China
it is rarely used in small power local railways and instrial and mining locomotives
China's main line diesel locomotives are mainly electric drive Dongfeng type
now hydraulic transmission is relatively rare, but the former special trains used to be made by ny6, Hansel factory of Federal Germany There is only one diesel locomotive with electric drive driven by NY7. Dongfeng 11z made by Qishuyan Locomotive and rolling stock works is used for traction of special train. By the way, the function of diesel locomotive transmission device is not obvious when the fuel supply per cycle is fixed; The power of diesel engine is approximately proportional to the speed, and it can reach the rated power only at the rated speed. In order to make full use of the power of diesel engine and realize the requirements of locomotive traction characteristics, diesel locomotive must be equipped with transmission device, which is the intermediate link between diesel engine crankshaft and locomotive moving shaft. The torque, power speed characteristics of diesel engine are converted into the traction characteristics of diesel locomotive: that is, the locomotive has greater traction when starting and low-speed traction; After the train starts, when the handle of the main controller of the locomotive is at a given position, the speed and power of the diesel engine are fixed, and the train running resistance is less than the traction force of the locomotive (the acceleration force is positive), the speed of the locomotive increases along the traction characteristic curve (the traction force decreases accordingly); When the train resistance is greater than the locomotive traction force (the acceleration force is negative), the locomotive speed decreases along the traction characteristic curve (the traction force increases with it); At the same time, through the transmission device to achieve locomotive reversing, power braking and other conditions conversion function, to meet the requirements of train traction< (1) main line diesel locomotives include freight diesel locomotives and passenger diesel locomotives; Shunting diesel locomotive and shunting diesel locomotive with small operation; Instrial and mining diesel locomotive; Diesel locomotive for local railway
(2) diesel locomotives can be divided into electric drive, hydraulic drive and mechanical drive. Electric drive diesel locomotive can be divided into DC drive, AC drive and AC drive diesel locomotive. Hydraulic transmission diesel locomotive can be divided into ordinary hydraulic transmission, hydraulic mechanical transmission and hydraulic reversing diesel locomotive. The latter is called hydraulic reversing diesel locomotive for short
(3) according to railway gauge: standard gauge, wide gauge and narrow gauge diesel locomotives. The standard gauge is 1435mm; There are four kinds of wide gauge: 1520mn, 1600mm, 1665mm and 1676mm; There are 19 kinds of narrow gauge from 597mm to 1219mm, and the typical ones are 600mm, 762mm, 900mn, ooomm and 1067mm. The latter two kinds of gauge locomotives are generally called meter gauge locomotives
(4) according to the number of main diesel engines installed on locomotives: single unit diesel locomotive and double unit diesel locomotive
(5) according to whether or not to implement multiple locomotive, there are two types: non multiple diesel locomotive and multiple diesel locomotive
(6) according to the structure of running gear: frame diesel locomotive and bogie diesel locomotive
(7) according to the number of Locomotive Axles: two axle, three axle, four axle, five axle, six axle and eight axle diesel locomotives
(8) according to axle type of locomotive: A-A, a0-a0, B-B, b0-b0, b-b-b, B0-B0-B0, C-C, C0-C0, D-D, d0-d0, a01a0-a01a0, aaa-b axle diesel locomotive
(9) according to the number of cabs: single cab, double cab and no cab<
composition of diesel locomotive
diesel locomotive is a locomotive with internal combustion engine as power unit. Note: most internal combustion engines for railway locomotives are diesel engines
diesel locomotive is composed of the following parts: diesel engine, main transmission device, auxiliary transmission device, car body (including cab), running gear and auxiliary systems
locomotive auxiliary system includes: fuel system, oil system, cooling water system, preheating system, air braking system and other air systems, control system, lighting system, charging system, detection system, diagnosis system, display and recording system, etc<
briefly speaking, the most widely used AC / DC electric drive locomotive's action principle
locomotive battery supplies 96V to start 80kW to start generator
start generator engine, locomotive diesel engine runs to drive synchronous main generator, 45KW inctor exciter outputs DC to synchronous main generator rotor through rectification to excite the main generator to generate electricity normally
(when diesel engine is running) After the generator runs, start the generator and turn it into a separate generator to generate 110V constant DC, which is used to supply the air compressor and some locomotive auxiliary equipment, and then charge the locomotive battery)
the synchronous main generator generates three-phase AC, which is used to supply six DC traction motors through the main rectifier cabinet
finally, Locomotive starting
it's much simpler to teach diesel locomotive the structural principle of electric locomotive
too much to introce casually
electric locomotive is a locomotive that obtains electric energy from catenary and then uses traction motor to drive, which is not a locomotive with its own energy
types of electric locomotives
1. DC electric locomotives
this kind of locomotives has been widely used in trams, subways, railway transportation and other aspects in China. However, e to the influence of catenary voltage, locomotive power is limited to a certain extent
2 Single phase low-frequency AC electric locomotive
this kind of locomotive uses single-phase commutator traction motor (now it also uses DC separately excited traction motor), the main problem is rectification
requires the use of lower power supply frequency, such as 16 and two-thirds Hz or 25 Hz
this kind of locomotive has been applied in Europe and America, and special power plants and frequency conversion devices need to be set up< Single phase power frequency AC electric locomotive (rectifier type electric locomotive)
this kind of locomotive is widely used in China, such as Shaoshan type 1, Shaoshan type 3, etc.
4. (1) locomotive with DC separately excited traction motor
like Shaoshan type 2
(2) Locomotives with AC commutatorless traction motor
AC-DC-AC system and AC-AC system have been applied in this system
such as ice type high speed EMU in Germany and DJ2 type in Zhuzhou plant
electric locomotives are composed of mechanical, electrical, electric, electric, electric, etc The principle of rectifier type and AC-DC-AC electric locomotive is briefly described below.
rectifier type electric locomotive:
single cross current is supplied by catenary - traction transformer in locomotive is reced voltage - DC power is supplied after rectification - traction motor is rotated to drive locomotive running.
AC-DC-AC electric locomotive:
single cross current is supplied by catenary Current catenary - step down of traction transformer in locomotive - transformation of DC through power converter - intermediate energy storage link (transition device between balance and isolation power supply and load) - transformation of DC power supply in intermediate link into DC power supply that can be adjusted smoothly through inverter The voltage of three-phase alternating current - three-phase AC asynchronous traction motor - three-phase asynchronous motor rotating traction locomotive
so far as that is concerned, the chaos is not comprehensive enough in fact
the problem is too big, so many working modes of locomotive are different
right, If you look at the above axle type of locomotive, you may not understand it. Let me explain it again.
axle type of locomotive is an expression that reflects the structure and characteristics of axle arrangement of locomotive running gear with the combination of English letters and Arabic numerals
the following numbers, letters and symbols are used to represent the axle type:
1, 2 and 3 represent the number of follow-up axles of running gear (bogie)
A, B, C and d represent the number of moving axles of running gear (bogie)
lower foot & quot; 0" It refers to the single axle drive of bogie wheelset, which is generally electric drive
no foot & quot; 0" It means that the bogie wheelset is driven in groups, which is generally hydraulic transmission
- the straight line indicates that there is no movable joint connection between the two bogies
+ indicates that there is a movable joint connection between the two bogies<
the axle type series of internal combustion engines are mainly as follows:
A-A and a-a-a are frame type locomotives, which have two and three groups of independent driving wheel pairs and hydraulic transmission
B-B and b0-b0 are bogie locomotives with two two axle Bogies and two sets of moving Wheelsets for each bogie; The former is group drive and hydraulic transmission; The latter is single shaft drive and electric drive
C-C and C0-C0 are bogie locomotives, which have two three axle bogies, and each bogie has three sets of moving wheelsets; The former is group drive and hydraulic transmission; The latter is single shaft drive and electric drive
2 (B-B) and 2 (b0-b0) denote two B-B locomotives and two b0-b0 locomotives
2 (C-C) and 2 (C0-C0) denote two C-C locomotives and two C0-C0 locomotives
B0-B0-B0 means that the locomotive has three two axle bogies, single axle drive and electric drive
B0 + b0-b0 + B0 means eight axle locomotive with four two axle bogies, two bogies at each end are connected by movable joints, wheel set single axle drive and electric drive
b0-2 means that the front bogie consists of two sets of moving wheelsets, which are driven by single axle and electric drive; The rear bogie consists of two sets of follow-up wheelsets. The former is called power bogie and the latter is called follow-up bogie
a01a0-a01a0 means six axle locomotive with two three axle bogies. The front and rear wheelsets of each bogie are power wheelsets, and the middle is follow-up wheelsets, which are single axle driven and electric drive.
