Gas generator set

Natural gas generator set is a new type of generator set developed and designed by absorbing international advanced technology and experience in combination with the needs of oil and gas field users in my country. Widely used in oil fields, mining, coking and other industries: Applicable fuels: natural gas, coking gas, gas and filtered straw gas.

Gas generator sets have the advantages of wide output power range, high reliability in startup and operation, good power generation quality, light weight, small size, simple maintenance, and low low-frequency noise. Generally, they have the following three advantages:

1. Good power generation quality. Since the generator set has only rotating motion when working, the ESC has a fast response speed and works particularly smoothly. The output voltage and frequency of the generator have high accuracy and small fluctuations. When the load is reduced by 50% and 75% when the load is suddenly added, the set will become intensive. Camel line is very stable. The electrical performance index is better than diesel generator set.
2. Good startup performance and high startup success rate. The time from a successful cold start to full load is only 30 seconds, while the international regulations stipulate that diesel generators will carry load 3 minutes after a successful start. The gas turbine generator set can guarantee the success rate of startup under any ambient temperature and climate.
3. Low noise and small vibration. Because the gas turbine is in a high-speed rotation state, its vibration is very small, and the low-frequency noise is better than that of diesel generator sets.

1. Product introduction of gas generator

Natural gas generator set is a new type of generator set developed and designed by absorbing international advanced technology and experience in combination with the needs of oil and gas field users in my country. Widely used in oil fields, mining, coking and other industries: Applicable fuels: natural gas, coking gas, gas and filtered straw gas.

The series of gas generators are officially authorized products of related companies, which have better performance, better quality and more guaranteed service among similar products. They are recommended products by the gas generator set department.


2. Advantages

Gas generator sets have the advantages of wide output power range, high reliability in startup and operation, good power generation quality, light weight, small size, simple maintenance, and low low-frequency noise. Generally, they have the following three advantages:

1. Good power generation quality. Since the generator set only has rotating motion when working, the ESC has a fast response speed, and the work is particularly stable. The output voltage and frequency of the generator have high accuracy and small fluctuations. When the load is reduced by 50% and 75% when the load is suddenly added, the set will become intensive Camel line is very stable. The electrical performance index is better than diesel generator set.

2. Good startup performance and high startup success rate. The time from a successful cold start to full load is only 30 seconds, while the international regulations stipulate that diesel generators will carry load 3 minutes after a successful start. The gas turbine generator set can guarantee the success rate of startup under any ambient temperature and climate.

3. Low noise and small vibration. Because the gas turbine is in a high-speed rotation state, its vibration is very small, and the low-frequency noise is better than that of a diesel generator set.


Three, lubrication system

Inspection and maintenance of lubrication system. Due to the fact that there are many operating parts in this type of unit, the operating conditions of the operating parts are poor, most of which are under high temperature and high impact load, and there are many parts that need lubrication, and the reliability of the lubrication system is more demanding, so pay attention to checking the lubricating oil Pay attention to the cleaning of the centrifugal filter and the oil filter of the oil quality, oil level, oil temperature and oil pressure of the system to avoid increased wear of the unit components due to poor lubrication and shorten the service life of the unit components. Increase maintenance workload.


Fourth, gas generator set and diesel generator set comparison

Gas generator sets are generally used for normal load, while diesel generator sets are usually emergency or backup power sources;

The gas source of gas-fired units is abundant, coalbed methane, natural gas, biogas, etc. can all be used as gas sources, while diesel units can only use diesel as fuel;

The overall benefit (generation value-maintenance cost) of gas-fired units is better than diesel units, and gas is more economical than dyeing oil.


Five, failure analysis

When a failure occurs, pay attention to analyze the cause of the failure from the failure phenomenon, and analyze the structure based on the principle. From the outside to the inside, the easy first is the difficult.

When a failure occurs, the following three questions should be considered first:

(1) What happened before the failure?

(2) What maintenance and overhaul work was performed before the failure occurred?

(3) Have you encountered a similar situation before? How to deal with it? In addition, when the unit is allowed to judge the problem during operation, it can be judged during operation.

The power range of the diesel generator set supplied by our company is 30kw-3000kw, which can meet the specifications of ordinary, automatic, four protection, automatic switching and three remote monitoring, low noise and mobile...
