(1) vibrations that produce in running of compressor 1 are easy to make the weld fracture of the first copper pressure-equalizing pipe 6, affect the normal use of source pump;
Complicated when (2) installing, bother during maintenance.
The utility model content
The utility model proposes a kind of dry evaporator source pump, solved the problem of the easy fracture of weld of prior art the first pressure-equalizing pipe 6.
The technical solution of the utility model is achieved in that the dry evaporator source pump, comprise compressor, condenser, the first expansion valve and evaporimeter, described compressor, condenser, the first expansion valve and evaporimeter form circulation line by Trunk Line, be connected with the first pressure-equalizing pipe on described the first expansion valve, the end of described the first pressure-equalizing pipe is connected to the exit of described evaporimeter, described the first pressure-equalizing pipe is provided with angle valve, and described the first pressure-equalizing pipe is flexible pipe.
As one preferred embodiment, also comprise the second pressure-equalizing pipe, an end of described the second pressure-equalizing pipe is connected on Trunk Line between described compressor and described condenser, and the other end is connected on the exhaust end angle valve of described compressor.
As one preferred embodiment, also comprise the cooling feed liquor pipeline of compressor liquid spray, one end of the cooling feed liquor pipeline of described compressor liquid spray is connected on Trunk Line between described condenser and described the first expansion valve, and the other end is connected on the air intake duct of described compressor.
As one preferred embodiment, the Trunk Line between described condenser and described the first expansion valve is provided with hand valve, device for drying and filtering, liquid-sighting glass and the first magnetic valve.
As one preferred embodiment, the cooling feed liquor pipeline of described compressor liquid spray is provided with the second magnetic valve.
After having adopted technique scheme, the beneficial effects of the utility model are: due to original the first copper pressure-equalizing pipe is replaced by flexible pipe, and the end of the first pressure-equalizing pipe is connected to the exit of evaporimeter, also be provided with simultaneously angle valve on the first pressure-equalizing pipe, the vibrations that not only can avoid producing in the compressor operating process cause the junction fracture of the first pressure-equalizing pipe, and this structure installs very simple, keep in repair also very conveniently, greatly alleviated staff's labour intensity.
