AI Technical Summary
The moving disk bearing seat of the existing scroll compressor has eccentric oil agitated inside the upper bracket oil tank, resulting in the loss of power consumption of the agitated oil and affecting the energy efficiency of the compressor.
A pump body assembly is designed, including a moving disc, a crankshaft and an eccentric mass. The crank and the crankshaft main body form a shoulder. The eccentric mass is arranged at the shoulder and is located at the outer circumference of the moving disc bearing seat. The outer circumference center line of the eccentric mass is concentric with the center line of the crankshaft main shaft. The moving disc bearing seat is inserted in the eccentric hole of the eccentric mass. The moving disc bearing seat and the eccentric hole can move relative to each other.
It effectively reduces the oil disturbance loss of the moving disk bearing seat, improves the energy efficiency of the compressor, reduces the risk of oil-deficient wear of the pump body during startup, and reduces the wind resistance loss of the first and second balance blocks.
