How is the construction of the cooling water pump and how does it work?The cooling water pump of the engine generally adopts a centrifugal water pump, which is mainly composed of a pump body, a pump shaft, an impeller, a water seal, an inlet pipe, etc. turning parts Working condition: the belt pulley outside the pump is driven by the crankshaft and driven by the water pump shaft The impeller rotates in the pump body to generate a rotating centrifugal force, and a partial vacuum is formed at the inlet pipe. The water enters the center of the impeller from the water inlet, and the impeller piece winds the water to the inner wall of the pump body. Due to the increase of the water flow rate, a certain pressure is generated. Then, the water outlet of the pump flows into the water jacket of the cylinder block to realize the circulation of the cooling system.
What is the role of lubricating oil in the engine lubrication system?
Lubrication: The cleaned oil is continuously sent to the friction surface of the engine running parts to form a good lubricating film (using the friction between liquids instead of rolling or sliding friction between solids) to reduce the movement and wear of the parts.
Cooling effect: Due to the circulating flow of the oil, a part of the heat generated by the friction can be taken away and the temperature of the machine is lowered.
Cleaning effect: It can take away the rubbed metal scraps, keep the friction surface of the machine clean and reduce friction.
Sealing effect: The oil layer between the piston and the cylinder wall can reduce the air leakage when the piston moves and increase the sealing between the piston and the cylinder wall.
What does the oil pump do and how does it work?
The function of the oil pump is to send the oil to the friction parts of the engine, so that the oil circulates in the lubrication road to ensure that the engine is well lubricated. The oil pump is mostly a gear pump, which is composed of a gear pump body, etc. When the engine is working, The camshaft drives the driving gear of the pump body to rotate. The gear squeezing oil flows along the inner wall of the pump from the oil inlet to the oil outlet, forming a low pressure, generating suction, and the oil in the oil tank is sucked into the oil inlet. The oil is more and more accumulated, so the pressure is increased, and the oil is pressed to the friction parts to achieve forced lubrication.
The average car owner knows that when the car oil is insufficient, the lubrication will often lead to poor lubrication, which will aggravate the degree of wear and tear, and it is easy to cause the accident of the burning shaft. Therefore, there is often a misunderstanding,turbocharger shaft that is, it is better to add more oil than the oil is too small, but in fact, too much oil is also likely to cause car breakdown. This is because when the oil is too much, the large end of the crank handle connecting rod will produce strong agitation, which will not only increase the internal power loss of the engine, but also increase the oil splashed on the cylinder wall, causing the failure of burning the engine oil, even Since the danger occurs. Therefore, the amount of engine oil should be controlled between the upper and lower scales of the dipstick.
As a large-scale mechanical travel tool, there are countless parts of the car that use bolts and nuts to link. Many car owners naturally believe that, for safety reasons, these key bolts are guaranteed to have sufficient early warning force, and the tighter the tightening is, the better, even many car repairers will naturally tighten the bolts during the maintenance process. Turn. However, if it is tightened for a long time, on the one hand, the link will be permanently deformed under the action of external force, and on the other hand, the bolt will be stretched and permanently deformed, and the early warning force will decrease, and even cause buckle or breakage. This creates an unnecessary danger.
Before the advent of summer, in order to cope with the high temperature to prevent the engine from overheating, many private car owners choose to tighten the fan belt to improve the engine cooling effect. In fact, the fan belt should maintain proper tightness and should stainless steel shaft not be over-tightened. Otherwise, it is easy to increase the bearing load, increase wear and increase power consumption, and also cause the pump shaft to bend, the belt is elongated and deformed, and the service life is shortened.
Many times we always complain that the car is malfunctioning because of quality problems, but according to the survey, more than 85% of the reasons for the failure of private cars every year are caused by improper maintenance. Even many young car owners have never even had in-depth maintenance of their car due to busy work. Be aware that proper car maintenance can reduce the failure rate by at least 80%.
