2results about How to "Avoid heat buildup" patented technology

This utility model relates to a two-stage cooling structure for the motor rotor of a compressor, comprising a front housing and a rear housing mounted together from left to right. A cooling inlet is connected to the right side of the motor cooling cavity located inside the motor housing. A high-pressure hot gas outlet is connected to the right side of the main compression flow channel. The high-pressure hot gas outlet is connected to a cooler via a high-pressure hot gas connecting pipe, and the cooling inlet is connected to the cooler via a cooling inlet connecting pipe. Several guide vanes are evenly distributed along the circumference on the right side of the impeller, and a drain outlet connected to the motor cooling cavity is provided on the left side of the motor housing. This utility model utilizes the high-pressure hot gas compressed by the compressor, which, after cooling, effectively cools the surface of the motor stator and rotor assembly, forming a closed gas circulation path inside the compressor, avoiding high-temperature accumulation and improving equipment operational reliability.

The utility model discloses a train squatting closet production mould in the technical field of squatting closet mould, including mounting seat, the hydraulic cylinder is fixedly installed on the mounting seat, be provided with the workstation on the mounting seat, be provided with the upper pressure mould on the output of hydraulic cylinder, the lower mould is slidably connected on the workstation, be provided with the cavity between the workstation and lower mould, be provided with buffer assembly in the workstation, buffer assembly includes pressure pipe and spring. The utility model discloses a pressure pipe and spring are combined buffering, wherein, the hydraulic cavity in pressure pipe forms multistage damping through spiral vortex hole and flow guide groove, and the air cavity utilizes the compressibility of air to absorb residual vibration, and the guiding structure of workstation is cooperated, reduces the vibration and impact in the stamping process, protects the mould structure from the resilience damage, ensures product size accuracy, prolongs the service life of mould simultaneously.
