How to understand the maintenance and use of small gasoline generators
1. gas. Intake and exhaust 1. Intake. No matter what kind of gasoline generator is equipped with an air filter, because the engine needs to be mixed with gas without impurities according to regulations, the engine cannot be run without an air filter, otherwise it will cause rapid engine wear. The air filter is divided into paper type and oil bath type. After the paper type has been used for a period of time, check whether the filter element is dirty or damaged, remove the dirt on the filter element, and replace the filter element if it cannot be removed. Oil bath type, after a period of use, the filter element can be cleaned with warm water with household detergent, then cleaned with clean water, and the filter element is thoroughly dried, and then soaked in the machine

What should be paid attention to in the operation of diesel generator set
What should be paid attention to in the operation of the diesel generator set? 1., when the diesel generator set is running under load without warming up after the cold start of the diesel engine, due to the high oil viscosity and poor fluidity, the oil supply from the oil pump is insufficient, and the friction surface of the machine is due to Lack of oil and poor lubrication, causing rapid wear, and even failures such as cylinder pulling and tile burning. Therefore, the diesel engine should run at idle speed after cooling and start to heat up, and then run with load when the standby oil temperature reaches 40 ℃ or above; the machine should start in low gear and drive for a certain mileage in each gear in sequence until the oil temperature is normal and the oil supply is sufficient After that, it can switch to normal driving.

Small diesel generator operation taboo
Error operation of small diesel generator 1: When the diesel engine is running when the oil is insufficient, the oil supply on the surface of each friction pair is insufficient due to insufficient oil supply, resulting in abnormal wear or burns. For this reason, before the start of the diesel generator and during the operation of the diesel engine, it is necessary to ensure sufficient oil to prevent cylinder pulling and tile burning due to lack of oil. Erroneous operation of small diesel generators 2: Stop immediately after the load is suddenly removed or the load is suddenly removed. After the diesel generator is turned off, the circulation of the cooling system water stops, the heat dissipation capacity is sharply reduced, and the heated parts lose cooling, which is easy to cause the cylinder head, cylinder liner, and cylinder The body and other parts are overheated, resulting in cracks, or

Mainstream diesel water pump models of Chinese manufacturing industry
What are the mainstream diesel engine models in China's manufacturing industry? Diesel engine water pumps are mainly divided into two types: one is a diesel engine water pump unit based on ZW self-priming sewage pump; the other is a diesel engine pump unit system based on a new strong self-priming pump and adding a set of vacuum auxiliary devices. The difference between the two types of diesel engine water pumps is that the purchase cost of the common type is lower, the self-priming height is only 4-5 meters, and the flow rate can only be 800 cubic meters, however, the new diesel self-priming pump with vacuum auxiliary system can reach a self-priming height of 8-9 meters, a fast water outlet time, and a flow rate of 2600 cubic meters per hour. Diesel engine water pump vacuum
