Common types of grease fittings: Straight pressure grease fittings M6M10×1. Angle pressure grease fittings M645°M10×145°. Each nominal diameter corresponds to an outer diameter, with the inner diameter varying according to thickness. Pipes are categorized into imperial and metric pipes. For a pipe with a nominal diameter of DN100, if it belongs to the international standard series (commonly known as imperial pipe), its outer diameter is 114.3mm. Below are precautions for cleaning grease fittings: Monthly greasing: It is best to apply grease once a month. Otherwise, if the shaft pin rusts completely and becomes immovable, it is usually due to the operator not applying grease diligently. Sealing gaps tightly: Sand, gravel, and other debris from construction can enter the gap between the oil seal and the pin sleeve. Generally, the gap should be tightly sealed with wire, plastic hose, or inner tube. Clean before assembly: Remove impurities, gravel, and dust before installing the new replacement parts.

Can taxes be refunded if a newly purchased car is scrapped due to flooding and a new car is purchased again?

If a newly purchased car is scrapped due to flooding and a new car is purchased again, the taxes cannot be refunded. Below is a relevant introduction to the characteristics of vehicle purchase tax: 1. Single scope of taxation: As a property tax, the vehicle purchase tax is levied on specific vehicles purchased, rather than on all property or consumer property, making it a narrow-scope special property tax. 2. Single taxation stage: The vehicle purchase tax is imposed once, not at every stage of production, operation, or consumption, but only at the specific stage when the vehicle exits circulation and enters the consumption field. 3. Single tax rate: The vehicle purchase tax is levied at a uniform proportional rate, which does not vary with the amount of the taxable object, making it simple to calculate and stable in burden, conducive to tax administration according to law. 4. Single taxation method: The vehicle purchase tax is levied ad valorem based on the taxable price of the vehicle purchased by the taxpayer, with price as the taxation standard, directly linking taxation to value—higher value results in higher tax, and lower value results in lower tax. 5. Tax is levied outside the price, and the tax burden is not transferred: The tax base of the vehicle purchase tax does not include the tax amount itself; the tax amount is added outside the price, and the taxpayer is the actual bearer of the tax burden, meaning the tax burden is not transferred.

What is the correct way to steer the steering wheel?

The correct way to steer the steering wheel: 1. When turning left, rotate with both hands together. When the hands are about to cross, keep the right hand stationary on the steering wheel, take out the left hand, place it on the right side of the steering wheel, and continue rotating. After that, alternate the left and right hands according to the pattern; 2. The same principle applies when turning right, just switch the left and right hands. Before steering, adjust your sitting posture properly. The principle is to keep the elbows slightly bent—neither too straight nor too bent. The arms should naturally extend forward, with the wrists just resting on the top edge of the steering wheel for better vehicle control. If both hands grip the steering wheel at the 9 o'clock and 3 o'clock positions, the arms should naturally be in a slightly bent and relaxed state.
