Description
Technical field
The utility model relates to Compressor Technology field, is specifically related to a kind of for forming the horizontal compressor of the continuous cooling circulations such as refrigeration system and air-conditioning system.
Background technique
Generally speaking, closed compressor can be divided into rotary compressor, reciprocal compressor and scroll compressor according to fluid compression mode, and rotary compressor is along with plunger is in the revolution of cylinder the inside and from transferring compressed fluid.This compressor, according to the difference of type, is divided into horizontal and vertical two types.
The horizontal compressor of routine techniques comprises shell, motor drive mechanism and compressing mechanism and lubrication unit, and shell has certain inner space; Motor drive mechanism is arranged on the left side of seal container shell, for generation of driving force; Compressing mechanism is arranged on the right side of shell, by the driving force pressurized gas of motor drive mechanism; Lubrication unit is used to each friction portion of compressor that refrigerator oil is provided, and these refrigerator oils are stored on the lower surface of shell, and along with the rotation of rotating shaft, refrigerator oil is sucked out and supplies with composition compression mechanical part.
The compressing mechanism of prior art as shown in Figure 1, mainly contain baffler 1, upper bracket 2, cylinder 3, undersetting 4, bent axle 5, encircle 6, the parts such as blade 7, wherein upper bracket has been provided with exhaust port, contains again exhaust valve plate and bluff piece at relief opening on the valve seat going out in structure.The working procedure of compressing mechanism is as follows: during compressor operation, be with dynamic crankshaft 5 rotations, thereby make to encircle 6 rotates in cylinder, constantly the low-temp low-pressure coolant media of suction is compressed into the gas of High Temperature High Pressure, the gas of High Temperature High Pressure backs down exhaust valve plate through the relief opening of upper bracket 2, thereby discharge cylinder 3, enter refrigerating circulation system.Yet, lubricated is the assurance of horizontal compressor normal operation, existing bent axle is in the enclosure spacing by upper bracket and undersetting, refrigerator oil by vacuum pressure conveying to each need be lubricated position, but because the height of the upper bracket of said structure is lower, the height of refrigerator oil left and right sides on the lower surface of shell is basically identical, horizontal compressor is because inner refrigerator oil suction port is for turning round rear end, axle center, and refrigerator oil consumption is large, rely on existing negative pressure system cannot meet lubricating requirement, there is the low problem of compressor compresses machine reliability, the phenomenon that even occurs lack of lubrication and burn machine.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of horizontal compressor to guarantee each slide part fuel feeding of compression mechanical part, finally makes compressor have high reliability.
The purpose of this utility model is achieved through the following technical solutions:
A kind of horizontal compressor, the shell cylindraceous that comprises horizontal placement, in shell, be provided with motor and the pump housing, the lower surface of shell stores refrigerator oil, the described pump housing comprises upper bracket and undersetting, bent axle and cylinder, bent axle is in the enclosure spacing by upper bracket and undersetting, cylinder is arranged between upper bracket and undersetting, motor is connected in series one with the pump housing by bent axle, in bent axle inner chamber in undersetting, Oil sucking device is installed, described Oil sucking device is provided with fuel sucking pipe, the submerge refrigerator oil of the lower surface that is stored in shell of the front end of described fuel sucking pipe, on the shell of opposite direction one side of fuel sucking pipe front end, be provided with the discharge tube of the refrigerant after compression being discharged to compressor, the clearance distance of described upper bracket and shell is less than the clearance distance of cylinder and shell.Because the clearance distance of upper bracket and shell is less than the clearance distance of cylinder and shell, by upper bracket, the inside of shell is divided into hyperbaric chamber and low pressure chamber, and the small gap that the refrigerant that compression produces becomes with shell by upper bracket flows to low pressure chamber, and on the shell of opposite direction one side of inlet port, be provided with the discharge tube of the refrigerant after compression being discharged to compressor, thereby keep the oil level in hyperbaric chamber lower than the oil level of low pressure chamber, refrigerator oil lodges in the inlet port of low pressure chamber, facilitate Oil sucking device oil suction, promote oil circulation in compressor, improve the reliability of compressor.
Concrete, between described upper bracket and internal diameter of outer cover, forming annulus, the area of annulus is more than or equal to the circulation area of outlet pipe, is less than or equal to the exhaust circulation pipe area of 10 times.Through verification experimental verification, this circulation area when this scope, undersetting one side in shell oil level all the time higher than the oil level of upper bracket one side, facilitate Oil sucking device oil suction.
The utility model has the following advantages and beneficial effect compared to existing technology:
The clearance distance of the utility model upper bracket and shell is less than the clearance distance of cylinder and shell, by upper bracket, the inside of shell is divided into hyperbaric chamber and low pressure chamber, and the small gap that the refrigerant that compression produces becomes with shell by upper bracket flows to low pressure chamber, and on the shell of opposite direction one side of inlet port, be provided with the discharge tube of the refrigerant after compression being discharged to compressor, thereby keep the oil level in hyperbaric chamber lower than the oil level of low pressure chamber, refrigerator oil lodges in the inlet port of low pressure chamber, facilitate Oil sucking device oil suction, promote oil circulation in compressor, and then flow to each slide part fuel feeding, improve the reliability of compressor.
