Some issues have arisen in the hydraulic system of the titanium reactor overturning machine during operation. The following analysis is provided regarding these problems:
I. Description of the Hydraulic System Issues in the Flipper Machine
1. When the hydraulic system starts under low-temperature conditions, the pump output oil pipe vibrates significantly.
2. During the no-load operation of the hydraulic system, the pump temperature rises rapidly and reaches a high level, exceeding 60°C within 30 minutes.
3. Due to the use of single-cylinder drive and electromagnetic directional switching, the hydraulic flipper lacks sufficient overturning torque. Additionally, the flipper frame bears force unevenly on one side during the flipping process, resulting in unstable operation. This imposes significant stress on the hinge bearings and bearing seats, leading to reduced service life of the hinge bearings and severe deformation of the flipper frame and bearing seats.
II. Analysis of Hydraulic System Issues in the Flipping Machine
1. Due to the insufficient flow capacity of the plunger pump's oil filter and the small diameter of the oil delivery pipe, the required flow rate cannot be met. This results in inefficient oil suction by the pump, higher pressure resistance in the delivery pipe, significant pressure loss, leading to rapid temperature rise of the pump. Additionally, severe vibration occurs in the delivery pipe during low-temperature operation.
2. During the tilting process of the titanium reaction vessel, the hydraulic system cannot achieve stepless speed regulation, and significant switching shocks occur when the electromagnetic reversing network reverses, leading to substantial impacts on the bearings and bearing seats by the tilting frame.
3. Although the stacked unidirectional throttle can regulate the speed of hydraulic cylinders, it results in high back pressure, excessive useless work, significant energy loss, leading to heat generation and substantial energy dissipation.
In response to the aforementioned issues of the hydraulic system in the reactor overturning machine, technicians proposed a modification plan, which has been successfully implemented in practice. The improved hydraulic overturning machine features reduced oil pipe vibration and lower hydraulic oil temperature. The use of a stacked hydraulic check valve enables reliable locking at any overturning position. The adoption of flow division and collection with a symmetrical bidirectional layout allows for automatic proportional distribution or centralized flow, ensuring high synchronization accuracy in bidirectional displacement and speed of hydraulic cylinders. The symmetrical arrangement of hydraulic cylinders enhances overturning torque, improves force balance in the overturning machine, minimizes deformation of the overturning frame and bearing support, and extends the lifespan of bearings and bearing housings. The implementation of electro-hydraulic proportional directional valves enables stepless speed control for starting, acceleration, deceleration, and stopping of the overturning machine, significantly improving operational efficiency while reducing impact during startup and shutdown. This results in better stability and higher safety for titanium reactors.
