Working principle of the present invention is as follows: when barreled lubricant oil oil pumping device normally works, weighing instrument 3 can show current lubricating oil product residuals weight in real time; When the minimizing along with lubricating oil product, the stressed reduction of Weighing cell module 2, its amount of deformation diminishes, thus the 4-20mA signal numerical value of its sensor diminishes, this signal feed back, to signal amplifier 1, integrates four signals through signal amplifier 1, amplifies and exports to weighing instrument 3; The numerical value of lubricating oil product weight constantly declines, and when being reduced to predefined value, weighing instrument 3 output alarm signal to control cabinet or central control chamber, thus realizes liquid level monitoring warning function.After control box 3 or central control chamber obtain alarm signal, send operational order, electromagnetic valve of gas circuit 9 dead electricity, electromagnetic valve of gas circuit 9 is closed, and pneumatic pump 10 quits work, and staff carries out changing bucket operation, reaches the function of carrying out changing bucket operation according to warning of weighing thus.
As shown in Figure 2, working procedure of the present invention is as follows:
Control box obtains electric, starts play button, electromagnetic valve of gas circuit 9 electric after, electromagnetic valve of gas circuit 9 gas circuit is opened, and pneumatic pump 10 normally works after ventilating; Five manually operated valves 7 of threeway are simultaneously in PB communicating state, adjust to suitable pressure by reduction valve 8 simultaneously, keep upper bracket 11 to be with pneumatic pump 10 entirety reduce with oil drum liquid level and reduce.
Weighing instrument 3 on control box can show current lubricating oil product residuals weight in real time; When the minimizing along with lubricating oil product, the stressed reduction of Weighing cell module 2, its amount of deformation diminishes, thus the 0-10V signal numerical value of its sensor diminishes, this signal feed back, to signal amplifier 1, is converted into 0-20mA signal through signal amplifier 1, amplifies the weighing instrument 3 exported on control box; 4-20mA signal is converted into numerical value by the weighing instrument 3 on control box, shows in real time; The numerical value of lubricating oil product weight constantly declines with the work of pump, and when being reduced to predefined value, weighing instrument 3 output alarm signal on control box to control box or central control chamber, thus realizes liquid level monitoring warning function.
After control box 3 obtains alarm signal, send operational order, electromagnetic valve of gas circuit 9 dead electricity, electromagnetic valve of gas circuit 9 gas circuit is closed, and pneumatic pump 10 quits work; Staff carries out changing bucket operation.
Change a barrel operating process: carry out lifting operations, threeway five manually operated valves 7 switch to PA communicating state, and upper bracket 11 is with pneumatic pump 10 to rise overally; When upper bracket 11 is with pneumatic pump 10 to rise overally to top, threeway five manually operated valves 7 switch to meta state, keep upper bracket 11 state of rest; Pneumatic pump 10 entirety departs from 200L oil drum; After old bucket is replaced by new bucket, threeway five manually operated valves 7 switch to PB communicating state, and pneumatic pump 10 entire lowering is with by upper bracket 11; When upper bracket 11 is with pneumatic pump 10 entire lowering to the highest liquid level of new bucket, after laminating compresses, complete the whole barrel that changes and operate.
Start play button, pneumatic pump normally works.
