Perfect match of pump and thermostat
The engine is realized by the circulation of coolant. The component of the forced circulation of coolant is a water pump, which is driven by a crankshaft belt to promote the circulation of coolant throughout the system. Specializing in the production of water pumps for 40 years Feilongjiang Li's latest product - electric water pumps, it can accurately control the pump speed, and effectively reduce the loss of output power. The cooling of these coolants on the engine should be adjusted at any time according to the working conditions of the engine. When the engine temperature is low, the coolant circulates inside the engine itself. When the engine temperature is high, the coolant circulates between the engine and the radiator. The thermostat is used to control the coolant in different cycles. The thermostat can be regarded as a valve, its principle is to use materials that can be flexible with the temperature (paraffin or ether and so on) as a switch valve, when the water temperature is high material expansion top open valve, coolant for a large cycle, when the water temperature is low material shrinkage closed valve, coolant small cycle.

According to the cooling medium used, engine cooling methods can be divided into water-cooled and air-cooled.
1. Water-cooled one by one with water as the cooling medium, heat first from the machine to water, by the flow of water to heat away and then into the atmosphere. After heat dissipation, the water flows back to the hot part again. The normal working temperature of the engine can be maintained by properly adjusting the water and cooling intensity. At the same time, hot water can also be used to preheat the engine, which is convenient for starting in winter.
The structure of water-cooled cooling system: water pump, radiator, fan, thermostat, expansion tank, warm air, engine water jacket, cooling pipe.
2. the heat of air-cooled parts is directly scattered into the atmosphere.
At present, most of the cars are water-cooled.
