Abstract
The utility model discloses a lubricating system of a co-rotating parallel twin-screw extruder, which comprises an angle valve, one end of the angle valve is communicated with the oil outlet of a transmission case, the other end of the angle valve is communicated with an oil pump through a coarse strainer, and the oil pump is communicated with a pressure valve and a finer filter; the pressure valve is communicated with the oil return hole of the transmission case; and the finer filter is communicated with an oil distributor through a stainless steel plate heat exchanger, and the oil distributor is respectively communicated with each lubricating point joint in the transmission case. In the utility model, the stainless steel plate heat exchanger is adopted to exchange heat with water medium, so the system has the characteristics of high heat exchange efficiency, small flow resistance loss, corrosion resistance, long service life and the like; when filth blockage occurs to the pipe, the pressure valve is opened to form a bypass, so as to ensure stable oil level of the decelerated part of the transmission case; lubricating oil is supplied to each lubrication point through the oil distributor so as to realize forced feed lubrication and oil supply, thus the gear and the bearing can be prevented from being damaged due to oil starvation; and since the front end of the oil pump is provided with the coarse strainer, hard foreign matters can be prevented from entering the oil pump, and dirt matters can be easily removed.
Description
Technical field
The utility model relates to a kind of lubricating system, especially a kind of lubricating system of cocurrent and parallel double screw extruder transmission case.
Background technology
Cocurrent and parallel double screw extruder transmission case is because its transmission power is big, and rotating speed is high, and is very high for the requirement of the lubricant effect of gear and bearing.Domestic cocurrent and parallel double screw extruder transmission case all adopts oil-immersed type lubricated, and oil pump is extracted lubricating oil out from the bottom of transmission case, and through cleaner to multitube water-cooled heat exchanger, lubricating oil returns transmission case after cooling.There is following point in this lubricating system: 1) heat exchange efficiency of multitube water-cooled heat exchanger is low, owing to adopt copper pipe that cooling medium is required high (like the hydrochlorate degree of water temperature and water quality); 2) impurity of lubricating oil is blocked cleaner easily, increases oil circuit pressure, reduces oil mass, reduces the lubricating oil cooling effect; 3) the hard foreign matter of transmission case very easily gets into oil pump, breaks oil pump gear; 4) lubricating oil can not carry out forced feed lubrication to gear mesh, when oil level is low, can cause gear and bearing to damage because of oil starvation.
Summary of the invention
Goal of the invention: the purpose of the utility model is to solve the problems of the technologies described above, and provides that a kind of heat exchange efficiency is high, corrosion-resistant, level height is stable and the lubricating system of the cocurrent and parallel double screw extruder transmission case that can filter hard foreign matter.
Technical scheme: a kind of lubricating system of cocurrent and parallel double screw extruder transmission case; Comprise Angle valve; One end of said Angle valve is communicated with the oil-out of transmission case, and the other end of Angle valve is communicated with oil pump through coarse filter, and said oil pump is communicated with pressure valve and is communicated with fine filter; Said pressure valve is communicated with the oil return opening of transmission case; Said fine filter is communicated with separator through stainless steel plate type heat exchanger, and said separator is communicated with each inner oil site joint of transmission case respectively.
Further, said fine filter is provided with pressure switch, and said pressure switch connects warning device.
Further, said separator is provided with oil pressure gauge.
Further, be provided with flow control valve between said separator and the oil site joint.
Beneficial effect: the utility model adopts stainless steel plate type heat exchanger and aqueous medium to carry out heat exchange, and stainless steel plate type heat exchanger has characteristics such as heat exchange efficiency height, flow resistance loss are little, corrosion-resistant, long service life; The pipeline of oil pump to fine filter is established pressure valve, and dirty stifled when causing loine pressure high when fine filter, pressure valve opens that to form bypass stable with the oil level that guarantees the transmission case deceleration part; Lubricating oil carries out the forced feed lubrication fuel feeding for each oil site through separator, can prevent that gear and bearing from damaging because of oil starvation; At the oil pump front end coarse filter is set, prevents that hard foreign matter from getting into oil pump, and be easy to remove foul.
This lubricating system is used in the high torque drive case of cocurrent and parallel double screw extruder, and through operation, effect is splendid; In the high-revolving operation test of 72 hours full load, under the situation of 30 ° of cooling mediums, oily temperature is not higher than 50 °.
Description of drawings
Be illustrated as the structural representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
As shown in the figure, the lubricating system of the cocurrent and parallel double screw extruder transmission case of the utility model comprises Angle valve 1, coarse filter 3, oil pump 4, pressure valve 5, fine filter 6, stainless steel plate type heat exchanger 8 and separator 9.
One end of Angle valve 1 is communicated with the oil-out that is arranged on the transmission case bottom sides 2, and the other end of Angle valve 1 is communicated with oil pump 4 through coarse filter 3, and coarse filter 3 can prevent that hard foreign matter from getting into oil pump 4, and is easy to remove foul.
Oil pump 4 is communicated with pressure valve 5 and is communicated with fine filter 6, and pressure valve 5 is communicated with the oil return opening 7 of transmission case.Dirty stifled when causing loine pressure high when fine filter 6, pressure valve 5 is opened the formation bypass, and lubricating oil refluxes through the oil return opening 7 of transmission case side, to guarantee the oil level of transmission case deceleration part.Fine filter 6 is provided with pressure switch, and pressure switch connects warning device, and dirty when stifled when fine filter 6, pressure switch is to warning device output pressure alarm signal.
Fine filter 6 is communicated with separator 9 through stainless steel plate type heat exchanger 8, and said separator 9 is communicated with each inner oil site joint of transmission case respectively.Lubricating oil carries out heat exchange through stainless steel plate type heat exchanger 8 and aqueous medium, and stainless steel plate type heat exchanger 8 has high, the characteristics such as flow resistance loss is little, corrosion-resistant, long service life of heat exchange efficiency.Lubricating oil carries out the forced feed lubrication fuel feeding for inner each oil site of transmission case through separator 9.For the ease of observing charge oil pressure, oil pressure gauge 10 is set on separator 9.In addition, between the oil site joint of separator 9 and transmission case deceleration part, be provided with flow control valve 11, with the oil mass of each fuel feeding point of balance.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
