Abstract
The utility model relates to a filter type lubricating oil separator structure of a marine cold store refrigeration device. The filter type lubricating oil separator structure is characterized in that a separator is a closed metal tank, an oil storage cylinder (4) is arranged at the bottom in the tank, an oil filtering layer (1) is arranged at the upper part of the tank, a gas inlet (12) and an exhaust port (13) are arranged in the same direction on the outer side of the tank, a floating ball (3) and a needle valve (5) are arranged in the oil storage cylinder (4), and lubricating oil in the oil storage cylinder (4) flows out of the needle valve and enters a crankcase of a compressor via an electromagnetic valve (8) and a throttle hole plate (11). The filter type lubricating oil separator structure has the beneficial effect that the separation effect is greatly improved.
Description
Technical field
The utility model relates to a kind of marine vehicle cool house refrigerating device filtering type oil separator structure.
Background technology
In the exhaust of marine vehicle cool house refrigeration compressor, be mixed with the oil droplet and the oil gas of lubricating oil inevitably, the effect of oil separator is exactly to separate the most of lubricating oil in the exhaust, makes it return crankcase.The input pipe of the lubricated separator of original coaxial-type and non-coaxial is in the outside top of oil water separator; Blast pipe is in the top of separator; The oil separator inferior separating effect of this structure, and the lubricating oil of separating is returned crankcase effectively do not control.
Summary of the invention
The utility model is to realize like this; Separator is an airtight metal can, and the bottom in jar is an oil drum, and top is the oil strain layer; The outside of jar is air inlet and exhaust outlet with the orientation; Ball float and needle-valve are arranged in the oil drum, and the lubricating oil in the oil drum flows out from needle-valve, gets into compressor crankcase through magnetic valve and restricting orifice.
Adopt the oil separator of said structure, when the refrigerant vapor that contains lubricating oil flow through oil separator, circulation area was bigger, and flow velocity lowers greatly, adds the several times transformation of flow direction, and separating effect improves greatly.When high-temperature exhaust air is walked around the oil drum in the separator,, be dissolved in cryogen in the oil and just be evaporated and drain the lubricating oil heating that accumulates in the tube.From separator leads to the return line of crankcase, choke block is housed, is used for preventing that oil return speed is too fast, to such an extent as to make the needle-valve serious wear.Magnetic valve in the oil return pipe prevents that parking period is not closed completely because of needle-valve, and exhaust drains back to crankcase, makes the suction pressure of compressor raise too fast.
Description of drawings
Fig. 1 is a filtering type oil separator structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing explains the concrete structure and the operation principle of the utility model.
Shown in accompanying drawing, after compressor air-discharging gets into from bottom (12), walk around the outside of oil drum (4), be upward through oil strain layer (1) then and flow to outlet (13).Row in oil droplet impinge upon on the wall, perhaps attached on the oil strain layer, oil droplet flows into oil drum (4) through porous barrier (2) downwards.When oil level was elevated to certain altitude in the oil drum, ball float (3) was opened needle-valve (5), and lubricating oil just returns crankcase in the tube under the pressure at expulsion effect, and needle-valve when oil level drops to a certain degree (5) is closed.
Oil separator is equipped with restricting orifice (11) in the return line of crankcase, be used for preventing that oil return speed is too fast.Magnetic valve (8) also is housed on the oil return pipe, and it is opened when compressor start, closes during shutdown.Filter (7) in order to prevent that impurity from stopping up restricting orifice or making closed electromagnetic valve not tight.
Claims (2)
1. a marine vehicle cool house refrigerating device filtering type oil separator structure is characterized in that, separator is an airtight metal can; Bottom in jar is oil drum (4); Top is oil strain layer (1), and the outside of jar is air inlet (12) and exhaust outlet (13) with the orientation, and ball float (3) and needle-valve (5) are arranged in the oil drum (4); Lubricating oil in the oil drum (4) flows out from needle-valve, gets into compressor crankcase through magnetic valve (8) and throttle orifice (11) plate.
2. oceangoing ship cold storage cooling device filtering type oil separator structure according to claim 1 is characterized in that, after compressor air-discharging gets into from bottom (12), walks around the outside of oil drum (4), is upward through oil strain layer (1) then and flows to outlet (13); Oil separator is equipped with restricting orifice (11) in the return line of crankcase, be used for preventing that oil return speed is too fast; Magnetic valve (8) also is housed on the oil return pipe.
