Abstract
The utility model discloses an installation structure of a diaphragm compressor compensation oil pump. The installation structure of the diaphragm compressor compensation oil pump comprises a compensation oil pump (2), a box connection cylinder (1), an oil returning hole (3) and an oil passing hole (4), wherein the box connection cylinder (1) is fixed on the outer wall of a crankshaft box (6), part of a crankshaft (5) which is stretched out of the crankshaft box is positioned inside the box connection cylinder, and the compensation pump is fixed below the box connection cylinder. Part of a plunger of the compensation pump is located inside the box connection cylinder, the slant oil returning oil is drilled on one side of the bottom of the box connection cylinder, wherein the side of the bottom of the box connection cylinder is connected with the crankshaft box, the oil passing hole is drilled on one side of the crankshaft box, and the oil returning hole is communicated with the oil passing hole after the box connection cylinder is installed. According to the installation structure of the diaphragm compressor compensation oil pump, the compensation pump is installed on the position of the box connection cylinder at one end of the crankshaft, and does not directly contact the box, oil produced by leakage of the compensation pump is left inside the box connection cylinder and flows back to the crankshaft box through the oil returning hole and the oil passing hole, and the problem that leakage of lubricating oil pollutes the production environment is solved.
Description
Technical field
The utility model relates to a kind of diaphragm type compressor compensation oil pump, specifically a kind of mounting structure of diaphragm type compressor compensation oil pump.
Background technique
Membrane compressor is a kind of positive displacement compressor of special construction, the characteristics that have that compression ratio is large, good airproof performance, pressurized gas do not polluted by lubricant oil and other solid impurity.Usually, diaphragm type compressor mainly is comprised of driving mechanism, cylinder part, lubricating oil system, air pipe parts, crankcase components etc.Press the working principle of membrane compressor, the lubricant oil in the diaphragm type compressor oil cylinder extracts by the compensation oil pump in crankcase.Traditional compensation oil pump is to be directly installed on the crankcase body; its oil inlet hole is to obtain in casing boring; seal form is to add the asbestos packing sealing, and this kind structure often can produce the oil leak problem because of machining accuracy and bolt strained inequality, thereby pollutes production environment.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of mounting structure of diaphragm type compressor compensation oil pump, can effectively prevent oil leak pollution production environment.
To achieve these goals, the technical solution adopted in the utility model is: a kind of mounting structure of diaphragm type compressor compensation oil pump, comprise the compensation oil pump, also comprise the casing extend neck, spill port and oil-through hole, the casing extend neck is fixed on the crankcase body outer wall, stretch out the outer bent axle of crankcase body and partly be positioned at the casing extend neck, the compensation oil pump is fixed on the below of casing extend neck, the compensation fuel feed pump plunger partly is positioned at the casing extend neck, the sidetracking that casing extend neck bottom is connected with crankcase body has oblique spill port, crankcase body one sidetracking has oil-through hole, and spill port and oil-through hole connect after the casing extend neck is installed.
As preferably, spill port is oblique.
The utility model compensation oil pump is installed in the casing extend neck place of bent axle one end, directly do not contact with casing, the oil that compensation oil pump seepage produces is stayed in the casing extend neck, flows back in the crankcase through spill port and oil-through hole, can not produce the problem that production environment is polluted in oil leak.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model integral installation schematic diagram.
Among the figure: 1, casing extend neck, 2, the compensation oil pump, 3, spill port, 4, oil-through hole, 5, bent axle, 6, crankcase body.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of mounting structure of diaphragm type compressor compensation oil pump, comprise compensation oil pump 2, also comprise casing extend neck 1, spill port 3 and oil-through hole 4, casing extend neck 1 is fixed on crankcase body 6 outer walls, stretch out crankcase body 6 outer bent axle 5 parts and be positioned at casing extend neck 1, compensation oil pump 2 is fixed on the below of casing extend neck 1, compensation oil pump 2 plungers partly are positioned at casing extend neck 1, the sidetracking that casing extend neck 1 bottom is connected with crankcase body 6 has oblique spill port 3, crankcase body 6 one sidetrackings have oil-through hole 4, and spill port 3 connects after casing extend neck 1 is installed with oil-through hole 4.
As preferably, spill port 3 is oblique, utilizes the lubricant oil deadweight to be convenient to reflux.Spill port 3 also can be parallel hole, and its backflow effect is bad.
During work, because the effect of compensation oil pump 2, the lubricant oil that its plunger motion is taken out of is stayed in the casing extend neck 1, and lubricant oil flows back in the crankcase body 6 through oblique spill port 3 and oil-through hole 4, can not produce the problem that production environment is polluted in oil leak.
Claims (2)
1. the mounting structure of diaphragm type compressor compensation oil pump, comprise compensation oil pump (2), it is characterized in that, also comprise casing extend neck (1), spill port (3) and oil-through hole (4), casing extend neck (1) is fixed on crankcase body (6) outer wall, stretch out outer bent axle (5) part of crankcase body (6) and be positioned at casing extend neck (1), compensation oil pump (2) is fixed on the below of casing extend neck (1), compensation oil pump (2) plunger partly is positioned at casing extend neck (1), the sidetracking that compensation oil pump (2) casing extend neck (1) bottom is connected with crankcase body (6) has oblique spill port (3), crankcase body (6) one sidetrackings have oil-through hole (4), and spill port (3) connects after casing extend neck (1) is installed with oil-through hole (4).
2. the mounting structure of a kind of diaphragm type compressor compensation oil pump according to claim 1 is characterized in that, described spill port (3) is oblique.
