Summary of the invention
The purpose of the utility model is the deficiency to existing technology, provides a kind of a kind of improved water-cooled cryogenic refrigeration compressor bank that can effectively lower temperature of lubricating oil of compressor with and impurity to use external oil cooler.
For realizing above-mentioned technical purpose; The utility model adopts following technological scheme: a kind of improved water-cooled cryogenic refrigeration compressor bank is used external oil cooler; It comprises: compressor, oil cooler, oil pump and hand valve A; Compressor is the middle temperature helical-lobe compressor that comprises subsequent use oil inlet and subsequent use oil export, and subsequent use oil export connects oil cooler, hand valve A, oil pump and subsequent use oil inlet successively, wherein:
---also parallelly connected bypass valve between said subsequent use oil export and the hand valve A;
---connect oil strainer between said oil pump and the hand valve A;
---connection traffic switch between said oil pump and the subsequent use oil inlet;
---also distinguish parallelly connected modulating valve and one-way valve between oil strainer and the flow switch.
Further, said oil cooler is a water to oil cooler.
Further, establish hand valve C between the oil pump of said oil strainer and parallel connection, modulating valve, the one-way valve.
Further, establish liquid-sighting glass between said subsequent use oil inlet and the flow switch.
Further, establish hand valve B between said liquid-sighting glass and the flow switch.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is done further explain.
Embodiment
As shown in Figure 1, a kind of improved water-cooled cryogenic refrigeration compressor bank is used external oil cooler, and it comprises: compressor 1, oil cooler 2, oil pump 3 and hand valve A7.Compressor 1 is the middle temperature helical-lobe compressor that comprises subsequent use oil inlet 1-1 and subsequent use oil export 1-2.Subsequent use oil export 1-2 connects oil cooler 2, hand valve A7, oil pump 3 and subsequent use oil inlet 1-1 successively.Also parallelly connected bypass valve 6 between subsequent use oil export 1-2 and the hand valve A7.Connect oil strainer 10 between oil pump 3 and the hand valve A7.Connection traffic switch 12 between oil pump 3 and the subsequent use oil inlet 1-1.Also distinguish parallelly connected modulating valve 4 and one-way valve 5 between oil strainer 10 and the flow switch 12.
During proper functioning, hand valve A7 opens, oil pump 3 operations, and lubricant oil is back to subsequent use oil inlet 1-1 through oil cooler 2, hand valve A7, oil strainer 10, oil pump 3 successively in the compressor 1.It can effectively reduce the temperature of lubricant oil in the compressor, removes the impurity in the compressor lubricant oil, improves the stability of compressor and whole unit.
