centrifugal
A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.
Friction of the mechanical seal faces running together without lubrication or the shaft packing running against the shaft without cooling by water seepage are the result of pumps running dry. Impeller clearances are usually wide enough that the impeller and volute aren't damaged when dry running occurs, but if the pump uses the fluid media to maintain a balance or if tolerances are extremely tight and there is contact with the impeller and volute then galling, damaging, and possibly seizing the impeller could happen.

Screw
Electrician uses many tools while carrying out his job. Screw driver is one of the tools. He uses multimeter, wire stripper, screw driver, nose plier....many more depending on the equipment, panel devices.
centrifugal chiller
The type of chiller that uses a screw type impeller is typically known as a screw chiller. These chillers employ a twin-screw compressor, which compresses refrigerant using two rotating screws. They are known for their efficiency, reliability, and ability to handle large cooling loads, making them ideal for industrial applications and large commercial buildings. Screw chillers are also recognized for their low maintenance requirements and operational versatility.

An M6 screw is a type of metric screw with a diameter of 6 millimeters. It is commonly used in construction, machinery, and electronics for securing components together.
A 10 screw is a type of screw that has a diameter of 0.190 inches. It is commonly used in woodworking, construction, and other applications where a medium-sized screw is needed to fasten materials together.
A M5 screw is a type of metric screw with a diameter of 5 millimeters. It is commonly used in electronics, machinery, and automotive industries for securing components together.
Ahu (air handling unit) and chiller are both components of a building's HVAC system. The AHU is responsible for circulating and conditioning air, while the chiller is responsible for cooling the water that circulates through the building to remove heat. The AHU uses the chilled water from the chiller to help control the temperature and humidity levels in the building.
An M5 screw is a type of metric screw with a diameter of 5 millimeters. It is commonly used in mechanical applications to fasten components together, such as in machinery, equipment, and electronics.
An M4 screw is a type of metric screw with a diameter of 4 millimeters. It is commonly used in mechanical applications to fasten components together, such as in machinery, electronics, and furniture assembly.
