Description
Technical field
The utility model relates to a kind of compressor displacement regulating structure, relates in particular to displacement regulating oil-hydraulic cylinder in a kind of compressor displacement regulating structure.
Background technique
Compressor is a kind of gas to be compressed to high pressure from low pressure, kinetic energy is converted to a kind of machine of potential energy.Be mainly used in refrigerating field.
As seen from Figure 1: compressor generally is made up of oil hydraulic cylinder 1, bearing support 2, casing 3, motor end cap 4.And displacement regulating structure generally is made up of the oil circuit in oil hydraulic cylinder 1 and the casing 3; The effect of displacement regulating structure is to regulate aspirated volume for the variation according to load, avoids unnecessary energy output, to reach purpose of energy saving.
As seen from Figure 2: generally transfer piston rod 12, hold and transfer piston 13, displacement regulating oil-hydraulic cylinder 14, delivery space 17, displacement-regulating sliding piece 18 to form by rotor 11, appearance; During compressor loads, charge into refrigeration oil in the oil hydraulic cylinder, oil pressure promotes piston toward moving to right, and runs into the oil hydraulic cylinder right side until piston, and compressor is fully loaded.Piston moves right together by piston rod 2 drive slide blocks in this process, the compressor full load, and the slide block right side reaches maximal inspiratory capacity in the rotor right side at grade.This kind design can only be used on the compressor of fixing operating mode, but in other systems such as cryogenic system, because the variation meeting of operating mode is bigger, use fixed volume than (volume ratio of compressor (Vi) defines: the ratio of aspirated volume and delivery space) can cause the phenomenon of insufficient compression and overcompression, as shown in Figure 3.Volume ratio directly influences interior compression ratio.
Summary of the invention
The utility model technical issues that need to address have provided displacement regulating oil-hydraulic cylinder in a kind of compressor displacement regulating structure, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: rotor, appearance are transferred piston rod, are held and transfer piston, displacement regulating oil-hydraulic cylinder, delivery space, displacement-regulating sliding piece; Also comprise: volume ratio is adjusted connecting rod, volume ratio is adjusted screw rod, volume ratio adjustment seat; Described volume ratio adjustment seat be placed in hold to transfer piston rod and hold transfer between the piston and with the fusing of displacement regulating oil-hydraulic cylinder; In volume ratio adjustment seat, comprise with the volume ratio of holding an end vertical connection of transferring piston and adjust connecting rod; The upper and lower part that described volume ratio is adjusted two ends of connecting rod and volume ratio adjustment seat is connected airtight and is touched; Adjusting the bottom of connecting rod in volume ratio settles a connected volume ratio to adjust screw rod; The right side that described volume ratio is adjusted screw rod one end and volume ratio adjustment seat connect airtight touch, the other end passes the left side of volume ratio adjustment seat and connect airtight with it and to touch;
Compared with prior art, the beneficial effects of the utility model are: compressor be may operate in than the air conditioning condition of short volume ratio and the worst cold case of big volume ratio.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 4: the utility model comprises: rotor 11, appearance are transferred piston rod 12, are held and transfer piston 13, displacement regulating oil-hydraulic cylinder 14, delivery space 17, displacement-regulating sliding piece 18; Also comprise: volume ratio is adjusted connecting rod 15, volume ratio is adjusted screw rod 16, volume ratio adjustment seat 19; Described volume ratio adjustment seat 19 be placed in hold to transfer piston rod 12 and hold transfer between the piston 13 and with the fusing of displacement regulating oil-hydraulic cylinder 14; In volume ratio adjustment seat 19, comprise with the volume ratio of holding an end vertical connection of transferring piston 13 and adjust connecting rod 15; The upper and lower part that described volume ratio is adjusted two ends of connecting rod 15 and volume ratio adjustment seat 19 is connected airtight and is touched; Adjusting the bottom of connecting rod 15 in volume ratio settles a connected volume ratio to adjust screw rod 16; The right side that described volume ratio is adjusted screw rod 16 1 ends and volume ratio adjustment seat 19 connect airtight touch, the other end passes the left side of volume ratio adjustment seat 19 and connect airtight with it and to touch.
The utility model is adjusted screw rod by the rotation volume ratio and is adjusted the position that volume ratio is adjusted connecting rod, and the drive volume ratio that turns clockwise is adjusted connecting rod and moved right, and drives volume ratio counterclockwise and adjusts connecting rod to moving to left.During compressor loads, charge into refrigeration oil in the oil hydraulic cylinder, oil pressure makes to hold transfers piston toward moving to right, and drives displacement-regulating sliding piece together toward moving right by holding the accent piston rod, transfers piston to run into volume ratio adjustment connecting rod until holding, and this moment, compressor was in full load condition.When volume ratio was adjusted connecting rod and is in position, the left side, delivery space minimum, volume ratio reached 4.8, and when adjusting to position, the right side, delivery space maximum, volume ratio are 2.2.Volume adjusted can make connecting rod rest on the arbitrary position than adjusting screw rod, thereby realizes according to the most energy-conservation Vi value of different regulating working conditions, as shown in Figure 5.
