Description
Technical Field
The invention relates to the technical field of tilting gear control, in particular to a control method for pump reduction and energy conservation of a hydraulic station of a clamp type tilting gear.
Background
The slab continuous casting finishing process generally uses a hydraulic tilting gear to turn the slab by 180 degrees. The main pump of the hydraulic station of the tilting gear is 3-used and 1-standby in design and is independently supplied for tilting slabs of the tilting gear. Because the hydraulic load action interval of the tilting gear is longer and the single action flow is larger, the configuration of a variable pump and an energy accumulator of 4 90KW power motors is generally adopted by a plurality of tilting gear hydraulic stations in a factory.
After continuous casting, the off-line tilting gear has the operation rate of less than 10% per day, the lifting period of a traveling crane slab matched with the tilting gear is long, and the hydraulic pressure has the advantages of large power density, namely large thrust and large torque, capability of realizing low-speed large-tonnage motion, convenience in stepless speed regulation, quick dynamic response, high control precision and the like, but the energy loss is overlarge. On one hand, the hydraulic transmission efficiency is low, and the single action flow of the tilting gear is large; on the other hand, the utilization rate of the tilting gear is low, and the power consumption of ineffective 'pressure maintaining' when the hydraulic load does not work accounts for about 70%. Therefore, in order to reduce energy consumption, a hydraulic station control method of the clamp type tilting gear, which can reduce the investment of a pump and is energy-saving and environment-friendly under the condition of meeting the hydraulic load, is needed.

s2, controlling the A-arm belt blank to rise to 75 ℃, standing for 5 seconds, after a large-flow action is carried out by a large load, oscillating the pressure system of the hydraulic station to return to high pressure and low flow, and simultaneously returning the motor current to a low value, wherein the motor power is reduced as the flow of the constant-pressure variable pump is reduced;
s3, controlling the arm B to slowly descend to 0 degree, simultaneously controlling the arm A to ascend to 105 degrees, and after the arm A stands by for 2 seconds, the descending process is throttling;
and S4, controlling the arm A to descend to 0 ℃, and completing semi-automatic blank turning when the arm A and the arm B reach 0 ℃.
Further, the specifications of the A arm and the B arm are the same.
