What is the difference between t651 and t6?

T651 and T6 mainly have the following differences: Different internal stress: Generally, T6 has relatively large internal stress and is prone to deformation during processing. The most suitable state for processing should be T651, which is stretched on the basis of T6 to eliminate internal stress. Different states: T6 state: After solution heat treatment and cooling, it has reached high strength and no further cold working is performed. T651 state: After solution heat treatment and cooling, it has reached high strength, and then undergoes cold stretching by a stretching machine to eliminate residual internal stress after heat treatment, ensuring no deformation during subsequent deep processing to guarantee the precision of machined products.

What is the working principle of an oil pump?

"The working principle of an oil pump is: The suction and pressurization of oil are accomplished by the reciprocating motion of the plunger within the plunger sleeve. When the plunger is in the lower position, the two oil holes on the plunger sleeve are open, connecting the inner cavity of the plunger sleeve with the oil passage in the pump body, allowing fuel to quickly fill the oil chamber. When the cam pushes against the roller of the roller body, the plunger rises. Due to the movement of the plunger, fuel is squeezed out of the oil chamber and flows into the oil passage. This upward stroke is called the pre-stroke. When the plunger blocks the oil holes, the oil pressurization process begins. As the plunger moves upward, the oil pressure in the chamber rises sharply. When the pressure exceeds the spring force of the outlet valve and the upper oil pressure, the outlet valve is pushed open, and the fuel is forced into the oil pipe and delivered to the injector. Maintenance of the oil pump should pay attention to the following aspects: Water can corrode the oil pump, so substances containing water are prohibited from being vacuumed by the oil pump. For substances containing a large amount of solvent, first remove most of the solvent in an oven before using the oil pump for vacuuming. Use the vacuum pump in the correct sequence to prevent backflow. After using the vacuum oven, be sure to clean it thoroughly, wiping the glass window of the vacuum oven. Wipe off the surface rust-proof oil. Remove the rust-proof oil from the inner cavity of the governor and the fuel injection pump, and add the specified grade of lubricating oil."

What is szrtc parking?

Parking spaces adopt a prepayment method. Please complete the payment operation after parking before choosing to leave. Four major issues exist: Inappropriate site selection, unreasonable layout, lack of supporting facilities, and irregular management. The result is "seriously interfering with the normal traffic flow on roads, further exacerbating the urban traffic problems of 'difficulty in driving and parking'." Driving regulations: The "Urban Road Vehicle Parking Space Setting Standards" also propose that for one-way streets, on-street parking spaces should preferably be placed on the left side; for roads with two-way traffic, priority should be given to parking on the right side.

Can Flood-Damaged Cars Be Traded In for New Ones?

Flood-damaged cars can be traded in for new ones. Below is an introduction to flood-damaged vehicles: 1. Specific definition of flood-damaged vehicles: Water begins to accumulate in the vehicle, and internal components are damaged due to the water. Flood-damaged vehicles also have corresponding water submersion levels. 2. Classification of water submersion levels for flood-damaged vehicles: Level 1 is when water just reaches the vehicle's chassis, Level 2 is when water reaches half of the wheels, Level 3 is when water almost completely submerges the tires, Level 4 is when water reaches the engine hood, Level 5 is when water completely submerges the engine hood, and Level 6 is when water submerges the roof.

What Causes the Electronic Steering Wheel to Become Heavier?

Electronic power steering becoming heavier is mainly caused by: lack of lubrication in the steering gear, low tire pressure, vehicle battery discharge, and booster failure. Lack of lubrication in the steering gear: When the car's steering gear lacks lubrication, steering resistance will occur, and the steering wheel will become heavier. In this case, it is necessary to add lubricating oil or, if required, replace the power steering fluid. Low tire pressure: When the tire pressure of a car is too low, the contact area between the tire and the ground increases, leading to higher driving resistance, which makes the steering wheel feel heavier. In such cases, the tires should be inflated promptly. Vehicle battery discharge: The energy for the electric power steering system motor comes from the battery or the engine. The motor's energy is only needed during steering operations. If the car battery has been used for too long, it may affect the normal output of electric power assistance. In this situation, the battery should be replaced in time. Booster failure: If the car's electronic booster malfunctions, the steering wheel will become heavier. This issue requires specific analysis and should be checked further by professionals at a 4S shop or repair shop.

What are the reasons for a single-cylinder diesel engine being unable to crank?

Single-cylinder diesel engine being unable to crank is one of the situations where the diesel engine fails to start. Common causes include: improper assembly clearance, moving parts being stuck; valves pressing against the piston; small components such as pins, nuts, or gaskets loosening or breaking and falling into the cylinder sleeve, piston, or gearbox, causing jamming. Below are specific explanations of the common reasons for a single-cylinder diesel engine being unable to crank: 1. Improper assembly clearance, moving parts being stuck. For example, the connecting rod bearing seizing the crankshaft journal, or the piston getting stuck in the cylinder sleeve. The solution is to reassemble. 2. Valves pressing against the piston. The symptom is that the crankshaft cannot turn at a certain position but can be reversed. Possible causes include incorrect timing gear meshing or improper adjustment of the decompression mechanism. The solution is to reassemble or adjust the decompression mechanism. 3. Small components such as pins, nuts, or gaskets loosening or breaking and falling into the cylinder sleeve, piston, or gearbox, causing jamming. The solution is to inspect and remove them.
