Abstract
The utility model discloses a lubricating oil cooling device for a screw air compressor. The device comprises an oil-air separator, a minimum pressure valve, an air cooler and an engine oil filter oil inlet pipe, and is characterized in that an oil drain pipe of the air cooler is communicated with an oil inlet pipe of a water cooler by virtue of a pipeline; the water cooler consists of a sealed tank-shaped body and an S-shaped pipe arranged in the tank-shaped body; the oil inlet and an oil drain pipe are arranged on the sidewall of the tank-shaped body in a perforation way; the oil drain pipe of the tank-shaped body is communicated with the engine oil filter oil inlet pipe through the pipeline; the two pipe ends of the S-shaped pipe are communicated with a water source pipe and a drain pipe through the pipeline after hermetically penetrating through the pipe wall of the tank-shaped body respectively; a water inlet valve is connected in series with the water source pipe. The device has the advantages that circulating water and air are used for cooling the lubricating oil of the air compressor to reduce the temperature of the lubricating oil as cooling media, and cooling water is cyclically cooled by virtue of a cooling tower, so that good lubricating oil cooling effects are achieved, and the recycling of the cooling water is also ensured.
Description
technical field:
The utility model relates to oil circuit cooling equipment, particularly a kind of cooling unit of screw-rod air compressor lubricant oil.
background technique:
Pressurized air is the requisite energy of Chemical Manufacture, produces pressurized air at present with screw-rod air compressor, the cooling cooling or air-cooled method of air natural that all adopts of lubricant oil of air compressor.Its structure is outlet pipe and the deaerator pipeline connection of air compressor, the relief opening of deaerator filter core is drawn pressurized gas and is led to the gas equipment for the treatment of, and after the lubricant pipe serial connection minimum pressure valve of Oil-gas Separation, be communicated with air-cooled cooler oil inlet pipe carry out indirectly air-cooled, then the oil exit pipe of air-cooled cooler is communicated with the oil inlet pipe of oil strainer, main frame, by lubricated the oil main frame that refluxes.
Screw air compressor does not have oil hydraulic pump, and the circulation of lubricant oil is that the pressure difference producing by the pressure before filter core and main frame jet realizes.In the time of compressor operation, gas in deaerator is under the effect of minimum pressure valve, model plays pressure, force lubricant oil to pass through air-cooled cooler, enter oil cut-off valve through oil strainer again, to the upper and lower nozzle opening fuel feeding of main frame, the heat being produced to take away air in compression process, host work chamber is lubricated and is sealed simultaneously, reduce internal leakage.The fogging oil that sprays into compressor mix with air compressed after, then reenter deaerator through exhaust check valve.
But in the situation that temperature is high, particularly, in the situation of southern summer high-temperature, oil temperature is often higher, by the cooling temperature that cannot reduce of air at all.Oil temperature height not only affects the oil of lubricant oil, reduces its working life, also affects the working life of air compressor.
summary of the invention:
The purpose of this utility model is to overcome above-mentioned defect, and a kind of cooling unit of screw-rod air compressor lubricant oil is provided.
Scheme of the present utility model is: comprise air-cooled cooler, oil strainer oil inlet pipe, it is characterized in that: the oil inlet pipe pipeline connection of the oil exit pipe of air-cooled cooler and water-cooling cooler, water-cooling cooler is made up of the box shaped body of sealing, the built-in S shape pipe of box shaped body, on box shaped body sidewall, perforate is provided with oil inlet pipe, oil exit pipe, box shaped body oil exit pipe is communicated with oil strainer oil inlet pipe by pipeline, two end sealing formulas of S shape pipe through after box shaped body tube wall respectively with water source tube, waste pipe pipeline connection, in water source tube, be connected in series an inlet valve.
The utility model has the advantage of: the one, under the hot weather in summer of south, all carry out cooling air compressor lubricant oil as cooling medium with circulating water and air, lubricating oil temperature is reduced, and cooling water adopts cooling tower circulating cooling, not only make lubricant oil good cooling results, also ensured cooling water circulation use.The 2nd, in the situation that weather temperature is low, the air natural cutting oil that can be used alone, can reach the needs of production completely.
brief description of the drawings:
Accompanying drawing is the utility model structural representation.
embodiment:
The utility model comprises deaerator 2, minimum pressure valve, air-cooled cooler 3, oil strainer 5 oil inlet pipes, it is characterized in that: the oil inlet pipe pipeline connection of the oil exit pipe of air-cooled cooler 3 and water-cooling cooler 4, water-cooling cooler 4 is by the box shaped body of sealing, the S shape pipe composition that box shaped body is built-in, on box shaped body sidewall, perforate is provided with oil inlet pipe, oil exit pipe, box shaped body oil exit pipe is communicated with oil strainer 5 oil inlet pipes by pipeline, two end sealing formulas of S shape pipe through after box shaped body tube wall respectively with water source tube, waste pipe pipeline connection, in water source tube, be connected in series an inlet valve.
The lubricant oil that lubricant oil is drawn after air-cooled from deaerator 2, minimum pressure valve enters sky in water-cooling cooler 4 box shaped body, through indirectly cooling of S shape pipe, then enters oil strainer 5, main frame 1.In the time of low temperature, as long as close inlet valve, reach the energy-conservation object of closing down water-cooled.
