Screw pumps require screw-type air compressor oil. The types and maintenance methods of screw-type air compressor oil are as follows: Types of screw-type air compressor oil: There are mineral-based Aoliang screw air compressor oils, which generally have a service life of about 3,000 hours, and fully synthetic Aoliang air compressor oils, which have a service life of over 6,000 hours but are more expensive. You can choose according to your needs. Maintenance of screw pumps: When stopping the screw pump, first close the discharge stop valve, and then close the suction stop valve after the pump has completely stopped. Due to the relatively long length and poor rigidity of the working screw, it is prone to bending, which can cause operational issues. The shaft system connection must be well aligned; alignment is best performed after installation and positioning to avoid deformation caused by pipeline stress. The connecting pipelines should be independently fixed to minimize stress on the pump, etc.

Is It Normal for a Car's Drain Pipe to Drip Water?

It is normal for a car's drain pipe to drip water. The drain pipe is mainly used in light-duty vehicles, compact cars, and buses. Its structure consists of a double-layer corrugated pipe covered with a steel wire mesh sleeve, with clamping rings fitted over the straight sections at both ends. To enhance noise reduction, the corrugated pipe may include an expansion joint or mesh sleeve inside. The primary material of the drain pipe is stainless steel SUS304, while the clamps and connecting pipes can be made of stainless steel or aluminized steel. The methods to address dripping water from the car's drain pipe are: 1. Drive the vehicle for a while and park it on a slope with the front facing upward and the rear downward; 2. Press the accelerator pedal deeply several times to allow the accumulated water in the exhaust pipe to drain out promptly.

Can Car Tires Be Inflated with a Bicycle Pump?

Car tires can be inflated with a bicycle pump. Passenger cars typically use low-pressure tires with a recommended pressure range of 2.2 to 3.0 bar, while bicycle tires usually require 3.5 to 4.5 bar, which is higher than car tires. As long as the valve stem types match, a regular bicycle pump can be used to inflate car tires. The functions of tires include: 1. Supporting the vehicle's entire weight and bearing its load; 2. Transmitting traction and braking torque while maintaining road adhesion; 3. Absorbing shocks and vibrations during driving to prevent excessive vibration and premature damage to vehicle components; 4. Enhancing high-speed performance while reducing noise, ensuring driving safety, handling stability, comfort, and fuel efficiency.
