Most power equipment requires cranking before starting. Why?
Power machinery requires manual cranking before starting. This is a basic requirement. The purpose is to determine whether there is damage, foreign matter, or jamming inside the machine. :handshake
Not only before starting, but also after being shut down for a long time. In addition to the reasons mentioned above, there is also the need to pre-lubricate the bearings to reduce wear during startup.
Agree with what was said on the 1/2 floor. At the same time, for some corrosive/easy to crystallize/easy to freeze in winter and other moving equipment, this should be done before driving. At the same time, after stopping the pump, the materials in the pump should be drained and rinsed with water as much as possible. Pumps that are not in use should be cranked regularly. We require that pumps be cranked every three shifts. If problems are found, they will be dealt with immediately.
Supplement: Detect problems early to prevent overloading during startup
Regardless of whether the equipment is in use or on standby, it must be cranked. This is a rigid rule in equipment management.
In addition to the reasons analyzed above, there is also the need to crank the pump to the appropriate position to reduce the starting load of the motor and prevent sinking points from increasing the load on the motor and causing circuit problems.
Turn the car regularly, be prepared, follow the rules and regulations, and stay safe for a long time!
It doesn't have to be manual turning. Depending on the size of the shaft power, there is also electric or pneumatic turning.
Power equipment should be moving equipment.

It is required to crank the equipment regularly before starting the machine and when preparing the machine. Cranking the machine before starting the machine is to detect problems in the equipment in time. Most equipment problems are discovered during the cranking process, such as shaft locking, poor alignment of the motor and pump, etc. Personally, I think cranking has little effect on lubrication. It just requires some oil to be put into the bearing in advance, which has little effect. Prepare the car and turn it to prevent the shaft from deforming due to long-term immobility, preventing the shaft and bearings from rusting, etc.
