      China's shortcuts in automobile manufacturing industry
      Over the past nine years, China has become the world's largest automobile market and producer, with annual production and sales exceeding 25 million vehicles. China's automotive industry has also been the world's largest automotive industry in just a few years, driven by the huge domestic demand of the Chinese market. But there is not a strong enough component system to support the development of China's automobile industry. In March this year, the 2017 Top 100 list of global auto parts suppliers was officially unveiled. Unsurprisingly, Germany's Bosch Group continued to rank first with more than $46 billion in revenue, while German gearbox supplier Zeiff rose to second. From the third to the tenth ranking of parts companies are Magna, electronics, mainland, Aixin, modern Mobius, Virginia, Lear.
      In this ranking, China's highest ranking of parts companies is Yanfeng automotive interior system, followed by CITIC Deka ranked 71. And the selected parts enterprises are mainly single components. Feilong Jiangli supply water pumps for car plants.
      In contrast, there is no comprehensive automobile parts supplier in China's automobile industry.

      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.

      When the pump is damaged, we should pay attention to the following items when replacing.
      (1)   The real cause of the pump damage should be clear. Before replacing the pump, the radiator fan, thermostat and coolant should be determined.
      (2)   It is likely that pumps with similar shapes but suitable for different types of engines will occur, so before installing the pumps, a comparison should be made between the new pump and the old pump removed, or a check should be made on the part number of the pump and the type of the engine to determine whether the selected pump is suitable for the model being repaired.
      (3)   Water pump installation surface should be carefully cleaned and leveled.
      (4)   When installing the pump, wet the seal ring with coolant first. If you need to use sealant, be careful not to apply too much.
      (5)   Do not use the way of percussion pump shaft to install the pump. You should check the real reason for the difficulty of pump installation. If the excessive scale in the cylinder water channel leads to the difficulty of pump installation, steel wire brush or fine sand paper should be selected according to the scale situation. When installing bolts in water pumps, they should be tightened progressively in the direction of diagonal according to the prescribed torque, excessive tightening of bolts or causing damage to gaskets.
      (6) The tension of the pump belt must be strictly controlled according to the adjustment standard. Excessive tension of the belt, will cause bearing overload operation and early damage; and too small tension, easy to produce noise, serious pump can not work properly.
      Feilong Jiangli warm notes: If you can't replace it by yourself, please go to the warehouse.

      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.
