The work of the diesel generator is a loop process, then a unit is required to describe the metrics of this job during continuous loop operation. Generally, we are represented by the number of rotations per minute, called the speed. Radiation of diesel generator sets We generally use rot / division, ie r / min. Of course, the use of diesel engines is different, and the required speed is also different. The fixed equipment includes a diesel generator set, a water pump unit, and the like, and the transfer speed used is generally fixed, such as the 50Hz diesel generator set of 50 Hz diesel generated by 1500r / min. The speed of the marine diesel engine is low, and if the speed is higher than 1000R / min, it can be called a high-speed diesel engine. And some large ship's diesel engine may have only 100 turns per minute. For diesel generators, it is also important to maintain a reasonable speed, it can

What are the advantages of the diesel generator set? First we need to understand what is the panel of the diesel generator set. The cabinet is also a generator automatic control cabinet. When two and above, the power generator set is powered together to power supply, or when one or more generator sets are powered together to power supply, the diesel generator is required to achieve the requirements of the joint power supply, so that power is The machine works normally. Below, the company briefly introduces the advantages of the diesel generator set. Diesel generator set parallel advantages: 1. Maintenance, maintenance is more convenient for multiple units to use in parallel, can centrally dispatch, allocate active load and reactive load, can make maintenance, maintenance is convenient. 2, more economical, can put the small power unit of the appropriate table according to the size of the online load, to reduce the fuel and oil waste of the small load operation of high-power units. 3,

Insufficient engine power and continuous black smoke is excessive from most cylinders or all cylinders of the engine, and the fuel and air mixing ratio are disordered. When combustion, severe hypoxia, diesel combustion is incomplete, suspended free carbon elements The exhaust gas is formed together. If the exhaust pipe is intermittent black smoke, it is accompanied by \"Suscitation \", indicating that the individual cylinder is not complete. The main reasons have the following points: 1. Improper injection pump is quenched, so that the oil supply is too large, the combustion is incomplete. 2, the injection quality of most injectors is poor. 3, the oil supply is incomplete. 4, the opening of the intake door is lowered, the opening time is postponed, resulting in insufficient intake. 5, the air filter filter is too dirty or the air filter is installed, which is not smooth. 6. The supercharging efficiency of the supercharger is lowered. 7, the air quality is too bad. Jiangsu Xingguang Power Equipment Co., Ltd. founded in 197

There is a customer asking the engine of the diesel generator to low speed, but the speed of the acceleration cannot be increased, which is the lack of oil supply. Jiangsu Xingshui after-sales professionals to answer: (1) Problem Cause: 1 The fuel injection pump is not adjusted, so that the amount of oil supply is reduced. 2 The governor spring is lowered due to fatigue. 3 The fuel injection pump plunger and sleeve, the injector needle valve is severely worn by the needle valve body, which increases the water leakage in the pump oil, and the amount of oil is relatively reduced. 4 There is air in the oil road. (2) Treatment method: When the engine power is insufficient, if the low speed is good, the smoke is normal, it means that the engine combustion is good, that is, the diesel injection quality is good, the oil supply start time is normal, the cylinder is good, and the intake is sufficient. 1 In the normal condition of the low pressure oil, first check the looseness and connection of the throttle connections.

In the work, if you hear the exhaust of \"啪 \" around the cylinder, or hear the tap of\"咕咕 \" in the radiator, or check the cylinder pressure adjacent two cylinders The pressure is very low, and it indicates that the cylinder liner is damaged. (1) Cause 1 The engine fuel injection advances are too large, and the gas pressure rises too high, and the violent impact load is stripped. 2 The order and method of tighten the bolt bolt is not correct, the tightening torque is uneven, so that the cylinder liner is not fully bonded to the joint surface of the cylinder head. 3 The disassembly cylinder head is not followed by the program to deform the cylinder head. 4 The quality of the cylinder liner is poor, the thickness is uneven, especially the pads around the cylinder are uneven, and it is easier to be corrupted by high pressure gas. (2) Precautions 1 When installing the cylinder pad, the joint surface of the cylinder head and the cylinder block should be cleaned. 2 Pay attention to the orientation of the marker during installation, and the label is zero

Daily fuel tank: The daily fuel tank is supplied directly to the generator, so it should also be placed in the generator. The small unit of the small unit is provided with steel or plastic daily cylinders equipped with a fuel tube to a diesel engine. Such \"Bottom Filters\" can provide a minimum of 8 hours of full-load operation for diesel engines. Or, if you are equipped with a very large base fuel tank, it can run about 12 hours. Large storage cylinders: In order to extend the use time of the unit, a splitting machine, which is particularly important, especially for the alternate generator sets that do not regularly supply fuel. The big cylinder should generally be placed in place for the fuel, and should be easy to clean and examine, but should not be exposed to the wild in winter, because the oil will slow down due to increased viscosity. The cylinder can be placed on the ground or underground. The large cylinder must have a vent hole to release the air pressure generated due to the infusion of the fuel tank, or due to volatilization or expansion. It is also necessary to prevent oil.

1, the heat sink heat sink is blocked. Treatment method: find the cause of the problem, cleaning the heat sink; 2, the coolant is insufficient. Treatment method: Add a coolant; 3, the coolant fan is not working properly. Treatment method: Check the fan belt tension, replace the new belt if necessary; 4, the radiator is ventilated.

Based on the spirit of the user, the company regularly tracks the use of inspection equipment, solves all difficulties that users may encounter quickly and efficiently. On July 15, 2019, the company's after-sales service personnel went to the customer on-site to follow-up work on the unit, and made a simple maintenance work on the unit. The main work of maintenance and maintenance has the following points: 1. Comprehensive inspection of water, electricity, oil, gas, etc. of generator sets, ensuring normal operation. 2, replace the oil, diesel filter, oil filter and other parts. 3. The machine is fully dust removal. 4, an airborne test machine, record the performance parameters of the unit, and propose rational recommendations. The company visits users every year to understand the use of products, help solve the various situations that may encounter during use, while seeking quality improvement opinions in order to better

When the diesel generator sets enter the full-speed operation, when the voltage and frequency of the generator are normal, the staff puts the power generation machine, the unit during operation, the staff should often observe the operation of the unit, and make records . The shutdown operation of diesel generator sets mainly includes the following two points to note: 1, diesel generator sets: Once the diesel generator set fails, immediately press the emergency stop button on the control screen, and the unit is immediately stopped. If there is no emergency, I remember not to use the emergency stop button to turn off the running diesel generator set, which will cause harm to the service life of the diesel generator set. 2, diesel generator sets normal stop operation: Diesel generator sets before stopping the load, then the load is separated, and then the unit is run for a certain period of time, so that the unit will be fully cooled and then stopped. For installation
