Abstract
The utility model relates to an intermediate plate for increasing the oil amount for a compressor. The intermediate plate is arranged on a pump body, and provided with a gas drawing groove which is internally provided with an oil supply hole, a radial through hole is arranged at the front end of the gas drawing groove, an opening at the other end of the radial through hole is positioned on the upper surface of the intermediate plate, a side oil guiding through hole is arranged on the side surface at the upper part of the intermediate plate, and communicated with the radial through hole. Compared with the prior art, refrigerating machine oil in an oil tank at the lower part of a shell of the compressor is introduced into a piston and a blade tip end friction pair, the lubricating oil amount is added at the position, the abrasion loss is reduced, the mechanical efficiency is improved, and the safety and reliability of the compressor are ensured.
Description
Technical field
The utility model relates to a kind of compressor oil-drawing device, especially relates to a kind of intermediate plate that increases compressor oil-supplying.
Background technique
In refrigeration cycle; The effect of refrigerator oil is in lubricated, the cooling of compressor internal friction face and sealing etc.; But because all kinds of differences such as the structure of compressor, use refrigerant, running operating mode; The distribution that causes oil mass is very complicated, and problem such as also often have insufficient lubrication to cause the abrasion of friction pair bigger than normal, heating is deadlocked is serious even card cylinder phenomenon occurs.Special blade tip and piston external diameter are in boundary lubrication condition, and fuel feeding is to the lubricated decisive role that plays.Therefore, in order to ensure the safety reliability of compressor, it is very important increasing the lubricants capacity in the compressor friction pair and can not destroying normal lubricating oil path simultaneously.
The model utility content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned existing technology existence a kind of reduction abrasion to be provided, and improves the intermediate plate of the increase compressor oil-supplying of mechanical efficiency.
The purpose of the utility model can realize through following technological scheme:
A kind of intermediate plate that increases compressor oil-supplying is arranged between the upper and lower air cylinders, and intermediate plate is the disc-shape that an end is provided with handle shape structure; It is characterized in that air drain is pulled out in radially offering of intermediate plate, pull out and be provided with oil supply hole in the air drain; The front end that pulls out air drain is communicated with radial direction through hole; The opening of the radial direction through hole the other end is positioned at the edge of intermediate plate, and the side of intermediate plate offers side and draws oil hole, and this side is drawn oil hole and is communicated with radial direction through hole.
The described air drain that pulls out is a rectangular recess, and the oil supply hole that pulls out on the air drain links to each other with the oil-sucking hole of compression cylinder.
The opening of radial direction through hole is provided with sealing block.
Described side is drawn oil hole and radial direction through hole vertical connection.
Described side is drawn on the oil hole to install and is drawn oil pipe, and this draws in the oil sump at the bottom of oil pipe stretches into shell.
Compared with prior art; The utility model is through introducing piston external diameter and blade tip friction pair with the refrigerator oil in the oil sump of compressor housing bottom; The friction of piston external diameter and blade tip is boundary lubrication, and fuel feeding plays key effect to reliability, increases oil mass and can reduce abrasion; Improve mechanical efficiency, guarantee the safe and reliable of compressor simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 draws oil hole for oil supply hole, 4 is radial direction through hole, 5 for side for pulling out air drain, 3 for intermediate plate, 2 among the figure.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
A kind of intermediate plate that increases compressor oil-supplying; This device is for being arranged on the intermediate plate 1 between the upper and lower air cylinders; Its structure is as shown in Figure 1, and what offer the rectangular recess structure on the intermediate plate 1 pulls out air drain 2, pulls out and is provided with oil supply hole 3 in the air drain 2; Intermediate plate 1 is through linking to each other with the oil-sucking hole of cylinder pulling out the oil supply hole of offering on the air drain 23, and its internal pressure is basic identical.The front end that pulls out air drain 2 offers radial direction through hole 4; The opening of the radial direction through hole the other end is positioned at the upper surface of intermediate plate; Pulling out air drain 2 communicates with oil-sucking hole through radial direction through hole 4; The opening of this radial direction through hole 4 need use sealing block to carry out encapsulation process when general assembly, and the side on intermediate plate 1 top offers side and draws oil hole 5, with radial direction through hole 4 vertical connections.Side is drawn on the oil hole 5 to install and is drawn oil pipe, and this draws in the oil sump at the bottom of oil pipe stretches into shell.During operation; Gas flow rate was very fast when cylinder was air-breathing; When air-flow flows into the suction line of cylinder from the suction port of upper cylinder cover; The dynamic pressure that forms makes the oil-sucking hole place of cylinder and the pasta of housing inner cavity that is refrigerator oil produce pressure reduction, and this part pressure reduction can be introduced the refrigerator oil in the oil sump in the cylinder, and finally supplies with in the friction pair of piston.
