Shandong Generator Rental Manufacturer Analyzes Misconceptions about Generator Rental Usage
Misconception 1: Misuse of Generator Rental - There are clear specifications for the operating temperature of generators, yet some operators prefer to set the outlet water temperature very low, some nearly reaching the lower limit, and others even below it. They believe that a lower water temperature prevents cavitation in the pump and ensures uninterrupted cooling water flow, thus providing a safety margin. However, in reality, as long as the water temperature does not exceed 95°C, cavitation will not occur and the cooling water flow will not be interrupted. Conversely, excessively low water temperatures can be highly detrimental to the diesel engine's operation.
Firstly, due to the low temperature, the combustion conditions in the cylinder deteriorate, leading to poor fuel atomization. This causes an extended burn period after ignition, resulting in a rough engine operation and increased wear on components like the crankshaft bearings and piston rings. Consequently, power and fuel economy decrease.
Secondly, the water vapor after combustion is prone to condense on the tank wall, causing metal corrosion.
Thirdly, burning diesel may dilute engine oil, worsening the lubrication conditions.
Fuel combustion fails to form gums, causing piston rings to stick in the piston ring grooves and valves to become jammed. This leads to a decrease in cylinder pressure at the end of compression.
Fifthly, due to the low water temperature, the oil temperature is also low, causing the oil to thicken and its flowability to decrease. As a result, the oil pump of the Changsha generator rental has a reduced oil supply, leading to insufficient fuel supply for the Dongguan generator repair. Additionally, the decrease in the clearance of the crankshaft bearings contributes to poor lubrication.
Myth Two: Diesel generator set should have a lower speed.
Many operators are reluctant to work at the operating speed, believing that a lower speed won't cause any issues. In reality, excessively low speed can also lead to some adverse consequences:
A low RPM can reduce the diesel engine's output power and diminish its dynamism.
Secondly, excessively low RPMs can lead to reduced operating speeds of various components, which will degrade their performance and lower the output pressure of the oil pump.
The third measure reduced the reserve power of diesel engines, causing those that should be operating normally to work at full or overfull load; the fourth is that a low engine speed also decreases the rotational speed of the mechanical components of the linkage mechanism, thereby reducing the mechanical performance, such as lowering the water output of the pump and reducing the pump's lift.
