Specific embodiment
Understand for the ease of those of ordinary skill in the art and implement the present invention, with reference to the accompanying drawing and specific embodiment
The present invention is described in further detail.
As shown in Figure 1, the compressor of this programme, for pumping transfusion fluid, the cylinder of the compressor is provided with refrigerant inlet simultaneously
And refrigerant exit.
As shown in Fig. 2,3,4 and 5, a kind of compressor and its pump body structure defeated for liquid refrigerant pump.Its main feature is that should
Compressor is duplex cylinder compressor, is divided into upper cylinder and lower cylinder, and crankshaft 1 runs through upper cylinder and lower cylinder, upper cylinder and lower cylinder
Successively be sleeved on above crankshaft 1 from top to bottom for upper flange 2, partition 6, lower flange 3, upper cylinder body 4 setting upper flange 2 and every
Between plate 6, lower cylinder body 5 is arranged between partition 6 and lower flange 3, seals composition.It is set respectively inside upper cylinder and lower cylinder
Have and be fastenedly connected with crankshaft 1, with upper roller 7 and lower roller 8 that crankshaft 1 rotates, upper roller 7 and lower roller 8 respectively drive gas
Cylinder and lower cylinder imbibition drain, upper roller 7 and lower roller 8 are upper and lower interlaced arrangement, and upper cylinder is equipped with 9 He of upper cylinder feed pathway
Upper cylinder apocenosis passage 10, lower cylinder is equipped with lower cylinder feed pathway 11 and lower cylinder apocenosis passage 12, and upper cylinder feed liquor is logical
Road 9 and upper cylinder apocenosis passage 10 and lower cylinder feed pathway 11 and lower cylinder apocenosis passage 12 are symmetrically arranged in upper and lower, and two
Cylinder is connected to by the feed liquor intercommunicating pore 13 opened up on partition 6 with drain intercommunicating pore 14, and feed liquor intercommunicating pore 13 is arranged in upper cylinder
11 side of feed pathway 9 and lower cylinder feed pathway, the setting of drain intercommunicating pore 14 are arranged in upper cylinder apocenosis passage 10 and lower cylinder
12 side of liquid channel.
As shown in fig. 6, communicating passage also can be set on the pipeline outside the pump housing, interface channel is logical for upper cylinder feed liquor
Feed liquor connecting pipe 15 and upper cylinder apocenosis passage 10 between road 9 and the external pipeline of lower cylinder feed pathway 11 is under
Drain connecting pipe 16 between the external pipeline of cylinder apocenosis passage 12, pump body compression can be simplified as far as possible by being designed in this way
