oil pump introduce

The function of the oil pump in the lubrication system: The oil pump is used to increase the oil pressure to a certain level and force it to the moving surfaces of various parts of the engine. Its structure often adopts a gear type oil pump. When the engine is working, the crankshaft drives the active gear transmission, and the passive gear rotates in the opposite direction. The oil in the suction chamber is then pressed into the oil outlet chamber along the tooth gap and pump wall. As the oil in the suction chamber is continuously carried away, suction force is generated in the suction chamber, The oil pump continuously sucks the oil from the oil pan into the suction chamber and simultaneously pumps a certain pressure of oil into the lubricating oil circuit. In the lubrication system, the oil pump is a device that can force the oil from the oil pan to be sent to the moving parts of the engine. It is used to increase the oil pressure and ensure a certain amount of oil. The oil pump is a component that forcibly supplies oil to various friction surfaces. Gear type and rotor type oil pumps are widely used in internal combustion engines. Gear type oil pumps have a simple structure and are easy to process, Reliable operation, long service life, high pump oil pressure, and widely used. The rotor shape of the rotor pump is complex and is often pressed by powder metallurgy. This type of pump has the same advantages as gear pumps, but it is compact in structure and small in volume)

Installation method of diesel engine oil pump:

Installation method for diesel engine oil pump: 1. First, drain all engine oil, remove the engine oil pan, and replace the oil pump assembly; 2. The oil pump is the main component in the lubrication system of a diesel engine. Its function is to increase the oil pressure to a certain level and force it to the moving surfaces of various parts of the engine. The structure of the oil pump can be divided into two types: gear type and rotor type; 3. Gear type oil pumps are divided into internal gear type and external gear type, generally referred to as gear type oil pumps. 1. From the hole where the oil pump is installed, rotate the flywheel to rotate the cam to the back; 2. Seeing a fork, adjust the throttle so that the fork is in the middle position of the hole, place the gear rack on the oil pump in the middle position, and then carefully install it. Then, remove the speed limit screw in the gear compartment to see if the fork is forked against the gear rack. If it is not, repeat step 2. The oil pump of a single cylinder diesel engine is located in the lower left corner behind the large flywheel. Replacement steps for the oil pump of a single cylinder diesel engine: 1. Remove the large flywheel, and the oil pump can be seen in the lower left corner; 2. Unscrew the three bolts; 3. Remove the oil pump; 4. Fill the new pump with engine oil and install it

HiLux introduce

The Toyota HILUX (imported) TOYOTA HILUX is an SUV that leans towards road performance. Toyota has always been a loyal supporter of SUVs, and compared to the LC series PRADO, HILUX places more emphasis on road performance. Although it has been rooted in the North American market for many years and has sold over 1.2 million vehicles (known as 4RUNNER in North America), most people who buy it will not use it to travel mountains and rivers, The spacious interior and powerful design make it a competent SUV. Although the TOYOTA HILUX SURF provides passengers with a luxurious road riding experience, it still has a certain ability to endure hardships. The secret is the non constant TORSEN variable four-wheel drive mode, combined with the latest technology, similar to Land Rover's HDC downhill control system, which has TOYOTA's deep off-road capabilities, The powerful power system is also its advantage. Although it still uses the previous generation power system, the top tier 3-liter diesel engine can reach a maximum torque of 35.9kgm, and the North American version of 4RUNNER is even equipped with a top tier 4.7 displacement 235 horsepower gasoline engine
