Abstract
The utility model discloses an oil pressure unloader of a horizontal decanter centrifuge differential mechanism; the unloader consists of a set-up spring and a steel ball; the unloader is arranged in the central part of the differential mechanism; when the pressure is boosted to a certain value, the unloader can discharge less oil to keep the pressure balance of lubricating oil to avoid an oil seal from being destroyed by over-high pressure, thus allowing the differential mechanism to be fully filled with lubricating oil, thereby improving the lubricating conditions and leading the differential mechanism to run safely for a long period of time. The oil pressure unloader adopts a minitype one-way valve and is arranged at the output end of the differential mechanism. Under the spring effect of the one-way valve, the spherical surface of the sealed steel ball generates a pre-pressure to prevent the lubricating oil loaded in a shell from being lost. When the pressure generated by the expansion of oil caused by the increasing of oil temperature exceeds the pre-pressure of the spring, the oil drainage port of the unloader can drain the oil inside the shell to the outside to guarantee the pressure of the oil loaded in the shell to be under the pre-pressure of the spring, thereby protecting the completion of the oil seal. The oil pressure unloader of the horizontal decanter centrifuge differential mechanism can guarantee the lubricating state of the differential mechanism to be excellent and can reliably run for a long period of time.
Description
Technical field
The utility model relates to the interior fittings of centrifuge, especially horizontal screw centrifuger differential mechanism oil pressure relief arrangement.
Background technology
Differential mechanism is the critical piece of horizontal screw centrifuge, and the lubricated of the gear of differential mechanism and bearing is the key issue of guaranteeing that differential mechanism moves reliably and with long-term.Because the heat that the friction of the relative motion of differential gear and bearing (rolling bearing and sliding bearing) produces can make the temperature of lubricating oil raise, along with the rising of oil temperature, the lubricating oil volume can expand.If differential mechanism is filled lubricating oil, because the expansion of volume can make lubricating oil produce oil pressure, temperature high pressure more is big more, even can make the oil sealing breakage of sealing, causes leakage of oil, and then because of the lubricated damage that causes bearing, gear of oil starvation, differential mechanism lost efficacy.For avoiding the too high serious consequence of bringing of oil pressure, all be to take to pack into the lubricating oil of 2/3rds volumes at the differential mechanism of usefulness at present, the compressibility of the air in 1/3rd space by not pouring into oil reduces the rise of oil pressure.; because differential mechanism is along with the bowl rotation; under action of centrifugal force; the lubricating oil of 2/3rds volumes of packing into is thrown to the housing of differential mechanism; central part becomes the space of not having oil; can make the rolling bearing that is contained in central part only rely on the humour that has lubricating oil to soak when shutting down to lubricate,, can damage owing to the damaged rolling bearing of central part that makes of oil film if centrifuge is not shut down for a long time.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of horizontal screw centrifuger differential mechanism oil pressure relief arrangement.
The purpose of this utility model is to realize like this, horizontal screw centrifuger differential mechanism oil pressure relief arrangement, relief arrangement is made up of pre-compressed spring and steel ball, centre at differential mechanism is provided with relief arrangement, when pressure was elevated to certain value, relief arrangement can draw off a spot of oil made the pressure of lubricating oil keep balance.Avoid hypertonia and destroy oil sealing.So just can allow differential mechanism to fill it up with lubricating oil, and then improve lubricating condition, differential mechanism can long-term safety be moved.The oil pressure relief arrangement adopts micro one-way valve, is installed on the differential mechanism output.Under the spring action of check valve, the sealed steel ball sphere produces precompression, makes the unlikely loss of lubricating oil that is contained in the housing.When oily temperature rise causes the expansion of oil and when producing pressure and surpassing the precompression of spring, the drain tap of relief arrangement can outwards release the oil in the housing.Assurance is contained in the pressure of the oil in the housing under the precompression of spring, and then the protection oil sealing is intact.Can guarantee that the differential mechanism lubricating status is good, can move reliably and with long-term.
Described relief arrangement is made up of pre-compressed spring and steel ball.
Described relief arrangement is arranged on the differential mechanism output, and an end is slidingly connected with steel ball and differential mechanism.
The other end of described relief arrangement is connected with spring with drain tap.
Owing to adopted above technical scheme, the utlity model has following beneficial effect: can guarantee that the differential mechanism lubricating status is good, reliably and with long-term operation.
Description of drawings
Fig. 1 is the structure chart of the utility model horizontal screw centrifuger differential mechanism oil pressure relief arrangement.
In the drawings: 1-rolling bearing, 2-sliding bearing, 3-gear, 4-relief arrangement, 5-housing, 6-pouring orifice
The specific embodiment
As shown in Figure 1, the utility model horizontal screw centrifuger differential mechanism oil pressure relief arrangement, relief arrangement is made up of pre-compressed spring and steel ball, system comprises rolling bearing 1, sliding bearing 2, gear 3, relief arrangement 4, housing 5 and pouring orifice 6, in the centre of differential mechanism relief arrangement 4 is set, when pressure was elevated to certain value, relief arrangement 4 can draw off a spot of oil made the pressure of lubricating oil keep balance.Avoid hypertonia and destroy oil sealing.So just can allow differential mechanism to fill it up with lubricating oil, and then improve lubricating condition, differential mechanism can long-term safety be moved.Oil pressure relief arrangement 4 adopts micro one-way valve, is installed on the differential mechanism output.Under the spring action of check valve, the sealed steel ball sphere produces precompression, makes the unlikely loss of lubricating oil that is contained in the housing.When oily temperature rise causes the expansion of oil and when producing pressure and surpassing the precompression of spring, the drain tap of relief arrangement 4 can outwards release the oil in the housing.Assurance is contained in the pressure of the oil in the housing under the precompression of spring, and then the protection oil sealing is intact.Can guarantee that the differential mechanism lubricating status is good, can move reliably and with long-term.
