Specific embodiment
Below against accompanying drawing, by the description to optimum embodiment, specific embodiment of the present utility model is made into one
Step detailed description.
As shown in Figure 1, Figure 2 and shown in Fig. 4, this kind of refrigeration compressor oil pumping system, including the internal bent axle with lubricant passage way 9
1 and be connected to fuel sucking pipe 5 on bent axle 1, fuel sucking pipe 5 is provided with inlet port 6, is provided with and for fuel sucking pipe 5 is separated into three in fuel sucking pipe 5
The V-arrangement pump oil piece 2 of individual supercharging oil duct, three supercharging oil ducts are connected with inlet port 6 and lubricant passage way 9.
Lubricant passage way 9 on bent axle 1 has a discharge refrigerant passage 8, when bent axle 1 rotates, lubricating oil and cold-producing medium self-priming
The inlet port 6 of oil pipe 5 sucks, and when through V-arrangement pump oil piece 2, is divided into three strands by V-arrangement pump oil piece 2；Three strands of lubricating oil are based on V-arrangement
The structure of pump oil piece 2, the rate of climb is inconsistent, produces three kinds of lift, shorten lubricating oil from oil suction in three supercharging oil ducts
Mouth 6 is to the time of discharge refrigerant passage 8 on lubricant passage way 9 and bent axle 1 top.Because cold-producing medium is sufficiently mixed with lubricating oil,
When reaching discharge refrigerant passage 8, refrigerant gas overflow from discharge refrigerant passage 8, and refrigerator oil passes through lubricant passage way 9
Transmit oil into each kinematic pair, increase compressor pump oil lubrication effect, improve compressor pump oil mass simultaneously, realize compressor
Quick effectively lubricating.
The lateral cross section of V-arrangement pump oil piece 2 and 3 points of fuel sucking pipe 5 inwall are pressed into contact with.V-arrangement pump oil piece 2 and fuel sucking pipe 5 inwall
Cooperation, realizes triangle cylindrical support face and supports, and Stability Analysis of Structures is it is not easy to deform.Simultaneously because after increasing V-arrangement pump oil piece 2,
Compressor pumping ability improves, and especially adapts to frequency-changeable compressor lubricating requirement at the low rotational speed, meets compressor in variable working condition,
Reliability requirement under variable speed.
As shown in figure 3, fuel sucking pipe 5 stub end being connected by little head end and bent axle 1 and the mistake connecting little head end and stub end
Cross section to constitute；, inside the stub end of fuel sucking pipe 5, inlet port 6 is on little head end for V-arrangement pump oil piece 2.The aperture of inlet port 6
Typically in more than 4.5mm, V-arrangement pump oil piece 2 Stability Analysis of Structures is reliably arranged on fuel sucking pipe 5 on one end of bent axle 1, has value
Effect improves the lift of lubricating oil, so that the entrance bent axle 1 of lubricating oil fast and reliable, refrigerator oil passes through lubricant passage way 9 and passes oil
It is delivered to each kinematic pair, and cold-producing medium is run through discharge refrigerant passage 8 and discharge, realize the lubrication of compressor.
The length of V-arrangement pump oil piece 2 is adjusted according to required pressure during compressor pump oil, the length of V-arrangement pump oil piece 2
Bigger, lift during compressor pump oil is bigger.Preferably, the length of V-arrangement pump oil piece 2 is equal to the stub end of fuel sucking pipe 5
Length.Lift during compressor pump oil is bigger, and during compressor pump oil, required pressure is bigger, is capable of fast and reliable profit
Sliding.
As shown in Figures 5 and 6, V-arrangement pump oil piece 2 is by the first reinforcing sheet 3 and the second enhancing in angle with the first reinforcing sheet 3
Piece 4 is constituted；Fuel sucking pipe 5 inwall is divided into oil suction inside pipe wall first position 51, oil suction by the first reinforcing sheet 3 and the second reinforcing sheet 4
Inside pipe wall second position 52 and oil suction inside pipe wall the 3rd position 53；First reinforcing sheet the first side wall 31 and oil suction inside pipe wall first
The first supercharging oil duct is constituted between position 51；The is constituted between second reinforcing sheet the first side wall 41 and oil suction inside pipe wall second position 52
Two supercharging oil ducts；First reinforcing sheet second sidewall 32, the second reinforcing sheet second sidewall 42 and oil suction inside pipe wall the 3rd position 53 it
Between constitute the 3rd supercharging oil duct.First reinforcing sheet 3 and the second reinforcing sheet 4 are integral type molding structure, and structure is reliable and stable.
When bent axle 1 rotates, lubricating oil and cold-producing medium suck from the inlet port 6 of fuel sucking pipe 5, when through pump oil piece, by pump
First reinforcing sheet 3 of oil sheet and the second reinforcing sheet 4 are divided into three strands.Three strands of oil bases, in the architectural feature of pump oil piece, strengthen first
The lubricating oil that piece 3 and the second reinforcing sheet 4 are divided into is inconsistent due to speed, in three pressurised oil to three kinds of lift of interior generation, contracting
Short fuel sucking pipe 5 oilhole is to bent axle 1 top time, and improves compressor pump oil mass.
Angle between first reinforcing sheet 3 and the second reinforcing sheet 4 is between 25 ° to 60 °.The structure of V-arrangement pump oil piece 2 can
Lean on, stablize, stable and convenient is installed.
As shown in Fig. 7 A, Fig. 7 B and Fig. 8, as another embodiment, discharge refrigerant passage 8 do not processed by bent axle 1, inhales
The changeover portion of oil pipe 5 is provided with discharge refrigerant hole 7.Discharge refrigerant hole 7 is located at the changeover portion of fuel sucking pipe 5, works as fridge
When oily and cold-producing medium passes through the inlet port 6 of fuel sucking pipe 5, with the rotation of bent axle 1 high speed melody, oil is pumped to fuel sucking pipe 5 due to system
Cryogen is sufficiently mixed with lubricating oil, and when reaching discharge refrigerant hole 7, refrigerant gas overflow from discharge refrigerant hole 7；Lubrication
Oil is divided into three strands by pump oil piece in the stub end of fuel sucking pipe 5, and three strands of lubricating oil are respectively after three supercharging oil ducts are pressurized
Refrigerator oil transmits oil into each kinematic pair by lubricant passage way 9, increases compressor pump oil lubrication effect, improves pressure simultaneously
Contracting pump oil mass.Do not need on bent axle 1 to process discharge refrigerant passage 8 simultaneously, reduce the difficulty of processing of bent axle 1, cost-effective.
Although the patent publication us in background technology disclose oil-absorbing pipeline top, lower diameter dimension ratio size,
But inlet port 6 size of fuel sucking pipe 5 is not required；Pump oil amount is main in fact and inlet port 6 pore size of fuel sucking pipe 5
Relevant with bent axle major axis endoporus aperture and rotating speed, the size of oil-absorbing pipeline upper dimension is intended merely to join with bent axle bottom outlet interference
Close, only playing assembling needs.The aperture of inlet port 6 is adjusted according to required pressure during compressor pump oil, is meeting into oil
In the case of amount, the aperture of inlet port 6 is less, and pressure during compressor pump oil is bigger, and the aperture of inlet port 6 is more than or equal to 4.5mm.
This utility model refrigeration compressor oil pumping system, V-arrangement pump oil piece 2 is capable of triangle stable support, Stability Analysis of Structures,
Do not allow yielding, ensure that the functional reliability of oil pumping system it is ensured that compressor obtains proper lubrication.V-arrangement pump oil piece 2 simultaneously
Fuel sucking pipe 5 is separated into three supercharging oil ducts, after increasing V-type pump oil piece, compressor pumping ability improves, especially adapts to frequency conversion pressure
Contracting machine lubricating requirement at the low rotational speed, meets compressor reliability requirement under variable working condition, variable speed.
Obviously this utility model implements and is not subject to the restrictions described above, as long as employing method of the present utility model
The improvement of the various unsubstantialities that design and technical scheme are carried out, all within protection domain of the present utility model.
