Suggestions for purchasing mining generator
1. Compliance verification
Coal mine safety certification: MA/KC mark (mandatory for domestic mines)
International standards: MSHA (USA), ATEX (EU)
2. Cost optimization
Prioritize choosing the customized version for mining (15-20% more expensive than the general model, but with a 50% lower failure rate)
Long term maintenance contract (including on-site spare parts inventory)
3. Manufacturer recommendation
Domestic: Huaquan WC series, Huaquan YC series explosion-proof generator sets
International: Caterpillar (Explosion proof Series), Huaquan MTU Mining Edition
Concerns of Mining Generator Users
1.What are the reasons and solutions for the mine generator starting normally but the engine stalling shortly after?
Possible reasons:
1. Air intake into the fuel system (common reasons)
2. Fuel filter blockage
3. Malfunction of the shutdown solenoid valve
Handling method:
1. Drain the fuel system
2. Replace the fuel filter
3. Check if the solenoid valve operates when powered on
2.What are the reasons for the unstable and fluctuating output voltage of mining generators?
Possible reasons:
1. AVR (Automatic Voltage Regulator) malfunction
2. Unstable engine speed (frequency)
3. Poor contact of excitation system circuit
4. Nonlinear loads (such as frequency converters) generate harmonic interference
Handling method:
1. Check or replace AVR
2. Check the diesel engine governor and fuel system
3. Check all wiring and plugs
4. Add harmonic filters
3.What are the reasons and treatment methods for black smoke emitted by mining generator engines?
Possible reasons:
1. Insufficient intake (clogged air filter)
2. Poor or damaged atomization of fuel injectors
3. Overloading
4. Inaccurate fuel injection timing
Handling method:
1. Clean or replace the air filter
2. Check, clean or replace the fuel injector
3. Reduce the load to within the rated range
4. Adjust the fuel injection timing
