Retrofit Service

Turbocharger retrofit

1. Types of TC can be retrofitted

T/C series	Type
RH	RH133, RH143,RH163, RH183 etc
TPS	TPS44,TPS48,TPS52, TPS57, TPS61, A140
VTR	VTR160, VTR161,VTR 221VTR250, VTR251,
RR	RR131, RR151,RR181,RR211
VTC	VTC 214, VTC254
NR	NR12S,NR15R/S, NR20R/S,NR24R/S, NR26R/S
TCR	TCR12, TCR14, TCR16, TCR18, TCR20
HPR/KBB	HPR3000,HPR 4000,HPR5000,HRP6000, ST2, ST3, ST4, ST5, ST6
MET-SR	MET18SRC,MET30SR
NHR/Nappier	NHP20,NHP30,NHP180
NA	NA297

2. Why need to make T/C retrofit:

1）Old and outdated turbochargers, which need to improve overall performance.

2）Turbocharger has low reliability, high failure rate resulting in high maintenance cost

3）Difficult accessibility to spare part or high cost of spare parts,

3. Our advantage in turbocharger retrofit service

1）Professional team in design,manufacturing and service, able to provide users the efficiency and flexible turbocharger retrofit solutions .

2）We have more than 20 years of turbocharger practice, have accumulated rich field service experience in various application scenarios,such as site maintenance, overhaul and special parts repair for gas engine users.

5. Reference

1) Test result

Type of Genset：6N18L-SN; S/N:1903FSN;

Output power: 440kw;

RPM：720rpm

Type of old T/C : RH133, S/N: RH252459

Before

Operation records before replace RH133 T/C, Max output is limited in 160kw

Load	Engine speed rpm	Generator output kw	Scan air pressure bar	Scan air temp ℃	Exhaust gas temperature of each cylinders ℃
Load	Engine speed rpm	Generator output kw	Scan air pressure bar	Scan air temp ℃	1	2	3	4	5	6
25%	720	110	0.3	41	300	300	315	310	280	305
31.8%	720	140	0.25	50	330	340	320	315	340	305
36.4%	720	160	0.3	50	365	355	350	335	360	325

After

RH133 T/C have been replaced by TET151 T/C, test load reach upto 360KW, regular load can maintain at 330 KW during operation, the test records are as below:

Load	Engine speed rpm	Generator output kw	Scan air pressure bar	Scan air temp ℃	Exhaust gas temperature of each cylinders ℃
Load	Engine speed rpm	Generator output kw	Scan air pressure bar	Scan air temp ℃	1	2	3	4	5	6
25%	720	110	0.35	44	280	270	245	260	260	260

75%	720	330	1.5	55	325	340	320	350	350	325
	720	340	1.6	53	350	350	370	320	335	330
82%	720	360	1.6	58	310	320	340	360	370	350

Before retrofit, 6N18L-SN genset generally had common problem of high exhaust temperature and inability to increase the load, and the T/B frequently has trouble, and the maintenance cost was high. After replacement by TET151 T/C and performance of generator has largely improved. The advantages lies in below two:

1) After retrofit, the output of single generator is the output of the two old generators.

2) The reliability of T/C is largely increased. Maintenance interval is 10,000 hours.
