Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
as shown in figure 1, the invention comprises a gear box 11, a motor pump 6, a temperature sensor 2 and a ball valve 1, and is characterized in that the gear box 11 is connected with the temperature sensor 2 through a pipeline and used for monitoring the temperature of lubricating oil of the gear box 11, so that the start and stop control of the motor pump 6 is facilitated. Ball valve 1 sets up between gear box 11 and temperature sensor 2, and wherein ball valve 1 installs on the pipeline, and the fluid that can effectual control in the gear box 11 flows out.
The motor pump 6 is arranged between the solid particle size detector 5 and the strong magnetic solid particle filter 7, the motor pump 6 comprises a motor and an oil pump, wherein the motor and the oil pump can be directly connected and can also be connected through a bell jar and a coupler, the motor can be in 4-level, 6-level or 8-level, the oil pump is a delivery pump, and the delivery pump can be suitable for media with more particles.
Between oil absorption filter 3 and solid particle size detector 5, all be equipped with pressure measurement sampling joint 4 between strong magnetism solid particle filter 7 and the flow sensor 9, when the system operation, can connect pressure sensor 8 here in order to read corresponding pressure data, the pressure differential value of two positions can reflect fluid through solid particle size detector 5, the pressure value of loss behind motor pump 6 and the strong magnetism solid particle filter 7, through different temperatures, the pressure differential value under the different flow and the different pressure condition, thereby choose for use corresponding motor pump 6 and corresponding structure's washing nozzle 10 as required, in order to guarantee that washing nozzle 10 reaches due effect. The pressure measurement sampling joint 4 can also be connected with a sampling hose to sample oil, and the oil sample before and after the strong magnetic solid particle filter 7 is extracted is compared to know the oil condition after the oil passes through the strong magnetic solid particle filter 7.
Solid particle size detector 5 passes through the pipeline and links to each other with strong magnetism solid particle filter 7, wherein is equipped with strong magnetism filter core and filth in strong magnetism solid particle filter 7 respectively and blocks up the news transmitter, and when the solid particle of interception reached certain degree on strong magnetism filter core of strong magnetism solid particle filter 7 needs to be changed, the news transmitter can send out the suggestion of reporting to the police and change the filter core.
The strong magnetic solid particle filter 7 is connected with the flow sensor 9 through a pipeline, the flow sensor 9 is connected with the flushing nozzle 10 through a pipeline and used for monitoring the flow condition of the system during working, and whether the system breaks down or not can be judged according to the numerical value of the flow. Particularly, in a prototype test, whether the rotating speed of the motor needs to be adjusted or the structure of the nozzle needs to be changed is considered according to the flow rate and the working effect of the washing nozzle 10.
Washing nozzle 10 installs at gear box 11 inboardly, can improve the lubricated effect of gear to gear face oil spout, can wash impurity such as remaining solid particle on the gear box inner wall simultaneously.
The using process of the invention is as follows: an operator firstly opens the ball valve 1, oil in the gear box flows out of the ball valve 1 and then passes through the temperature sensor 2, the temperature sensor 2 judges whether the motor starting condition in the motor pump 6 is met or not by monitoring the temperature of the oil, when the oil temperature reaches the motor starting condition, the motor is started, then the oil flows to the oil absorption filter 3, at the moment, large solid impurities in the oil can be intercepted and filtered by the oil absorption filter 3, the oil passing through the oil absorption filter 3 flows to the solid granularity detector 5, the quantity and the distribution condition of solid particles in the oil are monitored in real time, then the oil flows to the strong magnetic solid particle filter 7 after passing through the motor pump 6, most solid particles in the oil are filtered, particularly, metal iron chips, aluminum chips and other particles in the oil, when the intercepted dirt of the strong magnetic solid particle filter 7 reaches a certain amount, dirt blocking signalling device above the strong magnetic solid particle filter 7 can send alarm signal, the suggestion renew cartridge and the strong magnetic filter core of clearance, fluid flow direction pressure sensor 8 and flow sensor 9 afterwards, if system pressure explains that certain position of system has a problem when crossing excessively, need the inspection, too low system pressure also makes the effect of washing nozzle 10 reduce or lose corresponding effect simultaneously, and flow sensor 9 can the flow of fluid among the monitoring system, the system flow of normal work is undulant at a certain within range, when the flow appears reducing comparatively obviously, judge through the state of looking over other sensors whether the system appears leaking. Finally, after the filtered clean oil flows to the washing nozzle 10, the washing nozzle 10 sprays the oil to the gear tooth surface, the bearing and the inner wall of the box body, which are not easy to be cleaned, so that the lubrication of the gear is improved, the corresponding heat on the bearing is taken away, and the damage caused by high temperature is avoided.
The data of corresponding sensors and instruments in the system can be used as a reference basis for replacing or maintaining the system: when the temperature value monitored by the temperature sensor 2 is normal, the flow value monitored by the flow sensor 9 is low, and the dirt blocking alarm on the ferromagnetic solid particle filter 7 does not give an alarm, the oil absorption filter 3 needs to be cleaned and the filter element needs to be replaced.
When the solid particle size detector 5 displays that more solid particles exist in oil for a long time, the flow value monitored by the flow sensor 9 is low, and the dirt blocking signal transmitter on the strong magnetic solid particle filter 7 does not give an alarm, whether the dirt blocking signal transmitter on the strong magnetic solid particle filter 7 is damaged or not needs to be checked, the strong magnetic filter element is replaced in time, and then monitoring is carried out.
When the pressure value monitored by the pressure sensor 8 is lower and the flow value monitored by the flow sensor 9 is normal, it indicates that the nozzle 10 is in a problem, the oil does not achieve the corresponding spraying and flushing effect, and the condition of the nozzle needs to be checked.
When the pressure value monitored by the pressure sensor 8 is lower and the flow value monitored by the flow sensor 9 is also lower, it indicates that a certain part of the system has leakage and needs to be checked.
Other undescribed portions of the present invention are the same as the prior art.
