The characteristics of gear lubrication pumps

When conveying high viscosity liquids, gear lubrication pumps should achieve a relatively high flow rate at lower power consumption, less leakage, and greater pressure. The viscosity of the liquid reflects the difficulty of medium flow. If the viscosity is too high, it will increase internal friction resistance and reduce output. The volumetric efficiency of wear and leakage will decrease, and the output power of the oil pump will be better than the input power. All losses will be converted into heat energy, which will cause the oil pump to overheat. The so-called sudden change in working conditions, It refers to the sudden abnormal phenomenon in the working condition of a car, which is a common symptom of a malfunction

For example, it is difficult to restart the engine after it suddenly stalls, and even cannot be started; The engine suddenly experiences a decrease in power while driving, resulting in weak driving performance; Sudden brake failure, deviation, or even failure during driving. The symptoms of this type of malfunction are obvious, so it is easy to detect

The gear lubrication pump is modified using Italian technology, with low noise and pollution resistance. The abnormal sound that occurs during the driving process of the car is the "alarm" for car malfunctions. When a sudden abnormal sound occurs during driving, as a driver, one should be aware that the car has a problem and immediately stop for inspection. The vehicle should not be allowed to work with a problem

The electro-hydraulic actuator integrates the motor, gear lubrication pump, and electro-hydraulic servo valve into one, and can work as long as the power supply and control signal are connected. The hydraulic actuator is similar to the cylinder, but can withstand higher pressure than the cylinder. Its operation requires external hydraulic pressure. In short, the above products require a large number of high-pressure plunger pumps, high-pressure gear lubrication pumps, high torque motors, wheel motors, multi way valves, oil cylinders, pipe fittings, pipeline assemblies, and oil filters, The market for hydraulic and sealing components used for supporting and repairing engineering machinery. During the operation of engines, the main components of normal combustion products should be carbon dioxide and a small amount of water vapor. If the engine combustion is not normal, the exhaust gas will be mixed with unburned carbon particles, carbon hydrogen compounds, carbon monoxide, and a large amount of water vapor. In addition, there are nitrogen oxides, etc. At this time, the color of the exhaust gas may turn black, blue, or white, That is to say, the exhaust smoke color is abnormal. For gasoline engines, there should be no obvious smoke in the normal exhaust. However, when the lubrication gear lubrication pump moves up the cylinder, the exhaust gas appears blue; When the combustion is incomplete, the exhaust gas appears black, and when water is added to the oil, the exhaust gas appears white
