Abstract
An ammonia refrigeration fast oil discharge device belongs to an ammonia refrigeration equipment, which is composed by a shell(1), an oil inlet valve(2), an oil discharge valve(3), a pressure reducing valve(4), a pressure gauge(5), a liquid level detector(6) and a differential pressure regulator of oil discharge device, the differential pressure regulator of oil discharge device is composed by an air inlet valve(7), a vacuum device(8), a check valve(9) and an exhaust valve(10). The oil discharge device can guarantee the oil discharge of high pressure equipment, also can ensure the low pressure equipment does not stop working and fast discharge oil. The oil discharge device is convenient to manufacture, using and maintenance, whose oil discharge time is as short as one quarter of original oil discharge time.
Description
The utility model relates to Ammonia Refrigerating Equipment, the device of particularly draining the oil.
The device of draining the oil also claims oil catcher, and it only is used for ammonia refrigeration system.Its effect is to deposit the lubricating oil of separating from oil eliminator, condenser, liquid reservoir, intercooler or evaporimeter, and abides by certain operational procedure of draining the oil the long-pending oil in the refrigeration system is emitted system under low-pressure state.The device of draining the oil mainly is made of housing, inlet valve, fuel outlet valve, pressure-reducing valve, Pressure gauge, content gauge etc.Housing is a steel garden tube; The pressure-reducing valve at top is connected with muffler, muffler generally is connected with ammonia liquor separator, as reclaiming cold-producing medium and reducing cylinder pressure, the inlet valve of garden tube upside is connected with oil inlet pipe, and low-voltage equipment or the high-tension apparatus that need drain the oil in oil inlet pipe and the ammonia refrigeration system are connected; Fuel outlet valve is contained in the downside of garden tube; Pressure gauge is contained in the upside of garden tube; Content gauge is contained in the middle part of garden tube.Ammonia refrigeration system is drained the oil and must be undertaken by certain operational procedure.When low-voltage equipment was drained the oil, its equipment need quit work, and treated that defueling equipment pressure raises, increase defueling equipment and the pressure differential between the device of draining the oil after, could in the device of draining the oil, drain the oil.Low-voltage equipment does not have pressure differential with the device of draining the oil just often, and therefore, the time of draining the oil is long.Drain the oil device in refrigeration system equipment is installed, and its absolute altitude is in extreme lower position.In order to solve this problem that to quit work of draining the oil of low-voltage equipment, application number provides a kind of " ammonia refrigeration system low pressure volume jettison gear " for 91219865.6, promptly increased by a jacket heating system in the bottom of low-voltage equipment, improve the flowability of oil in low-voltage equipment and the drain line, favourable draining the oil.Though this device does not quit work when low-voltage equipment is drained the oil, making, maintenance difficult, and the time of draining the oil is still long, and the device of draining the oil still need be installed in extreme lower position.For this reason, remain the device of draining the oil is further improved.
The purpose of this utility model: the innovation and creation ammonia refrigeration device of draining the oil fast, can ensure draining the oil of high-tension apparatus, very favourable again low-voltage equipment is drained the oil when not quitting work fast.
The utility model is achieved in that the ammonia refrigeration device of draining the oil fast is on the basis of original device of draining the oil, and increases the device differential pressure regulator of draining the oil and constitutes.With reference to accompanying drawing, the former device of draining the oil is made up of housing (1), inlet valve (2), fuel outlet valve (3), pressure-reducing valve (4), Pressure gauge (5), content gauge (6), and the device differential pressure regulator of draining the oil that intake valve (7), vacuum (8), check-valves (9), air bleeding valve (10) is formed by connecting by pipeline is connected in parallel on pressure-reducing valve (4) two ends.Drain the oil the fast operation principle of device of ammonia refrigeration is: start the device differential pressure regulator of draining the oil, take the ammonia of housing (1) internal upper part fast away, pressure in the device of draining the oil is reduced rapidly, make low-voltage equipment and drain the oil to form pressure reduction between the device fast, favourable low-voltage equipment is drained the oil fast.Housing (1) is made the garden tube with steel, and its external diameter is 150-520mm, and height is 600-1600mm.The vacuum in the device differential pressure regulator of draining the oil can be ammonia with vavuum pump or 50,70 serial ammonia refrigerating compressors.The ammonia refrigeration device of draining the oil fast is little because of vome of shell, and pressure is low, and the internal memory ammonia seldom also can intersect to the pipeline between the air bleeding valve (10) at check-valves (9) and is connected with a valve, and the emptying of the valve other end makes and extracts ammonia out and can put into air.
The ammonia refrigeration of the present utility model device of draining the oil fast, not only can ensure draining the oil of high-tension apparatus, and draining the oil fast can realize that low-voltage equipment does not quit work the time, simultaneously, can make the device of draining the oil be not interposing at the lowest order that is installed in refrigeration system equipment, the time of draining the oil only is 1/4th of the former time of draining the oil, and the device of draining the oil is made, maintenance is very convenient.
Accompanying drawing is a kind of structural representation of the present utility model, among the figure, be connected with inlet valve (2), fuel outlet valve (3), pressure-reducing valve (4), Pressure gauge (5), content gauge (6) on the housing (1), intake valve (7), vacuum (8), check-valves (9), air bleeding valve (10) are formed the device differential pressure regulator of draining the oil, and are connected in parallel on pressure-reducing valve (4) two ends.
Below in conjunction with embodiment, the utility model will be further described.
Embodiment: the JY-325 ammonia refrigeration device of draining the oil fast
As the ammonia refrigeration of the making device model of draining the oil fast is JY-325, promptly make the housing (1) of garden tube with steel, housing garden tube external diameter is 325mm, height can be 1070mm, connect fuel outlet valve (3) in housing (1) bottom, the Pressure gauge (5) that connects inlet valve (2) and vacuum type on top connects content gauge (6) at the middle part; Connect pressure-reducing valve (4) at the top, vacuum is selected 70 serial ammonia refrigerating compressors for use, with pipeline intake valve (7), vacuum (8), check-valves (9), air bleeding valve (10) are together in series, are connected in parallel on the two ends of pressure-reducing valve (4) then, all valves are selected the ammonia valve for use.Can constitute this routine ammonia refrigeration device of draining the oil fast.
When the device of draining the oil used, inlet valve (2) linked to each other with defueling equipment with other valve by pipeline, and pressure-reducing valve (4) links to each other with muffler.
Low-voltage equipment is drained the oil when operation: start the device differential pressure regulator of draining the oil earlier, ammonia is taken away, pressure reduces rapidly, then, opens low-voltage equipment and drains the oil in the device.Drain the oil finish after, close inlet valve, open fuel outlet valve, just the lubricating oil of draining the oil in the device can be emitted.
