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.

      Engine cooling water pump is the main part of the cooling system of automobile engine. Its function is to force the cooling fluid in the engine to circulate in the cooling system and reduce the influence of high temperature on the engine during the working process of the engine. Water seal is the core of the work of the pump. The movement of the water seal itself is very simple, just rotates with the shaft. . Water seal, pump body and bearing are super-hard matching mechanical seals. This kind of seals is composed of static rings and dynamic rings, which are perpendicular to the shaft, and the smooth and straight surface of each other, and do relative rotation. Coolant movement in the pump is very complex, different types of water seals, using different types of coolant, if the water package is equipped with problems, the engine coolant will appear seepage, then the pump bearing lubrication will be washed away, the entire pump function will be invalid.
      There are two main types of water seals: one is separated (rotating ring parts and static ring parts are respectively installed on the pump), the other is integrated (rotating ring parts and static ring parts are first installed together, and then installed on the pump), separated water seals are mainly used in larger pumps, now commonly used is integrated water seals.

      It is unavoidable that the breakdown of the automobile water pump is in use. Common faults are as follows:
      (1)   Bearing locking and fracture
      The causes of bearing failure may be the following aspects: bearing itself quality defects; bearing excessive impact load; product structure design defects; improper pump installation (such as knocking installation, belt tension, etc.)
      (2)   Leakage of installation surface
      The possible reasons for leakage of installation surface are as follows: uneven application of sealant, resulting in leakage of seam; improper installation of sealing gasket; leakage of pump sealing gasket or improper installation operation.
      (3)   Impeller damage
      Impeller damage is common in the form of impeller cracking, impeller loose from the pump shaft or impeller corrosion, impeller corrosion will not generally cause engine failure. When the impeller cracks or the impeller is loosened from the pump shaft, the coolant circulation speed becomes slower, which may easily cause the engine temperature to be too high. Damaged impeller may also impact the pump housing when rotating, causing cracking.
      If your car water pump is broken down , Feilong water pump can give you the prompt help.
