Problems solved by technology

For the 300,000 units in the thermal power plant, the current oil pressure signal pipe is connected to the monitoring and testing device, and the segmental test is realized through internal orifices of different sizes. The diameter of the orifice is less than 0.8mm, especially The orifice of the driving hydraulic oil is only 0.05mm. Once the foreign matter in the oil is blocked, it will cause the malfunction of the protection device, resulting in the interruption of the production process and even the refusal to damage the equipment, resulting in huge losses.

Abstract

The invention discloses an oil pressure online monitoring and testing system. The system comprises an oil pressure parent pipe and three source taking signal pipes connected to the oil pressure parentpipe in parallel, and the other ends of the signal pipes are connected with a tested device. The signal pipes are connected in parallel and then connected with an oil return pipe. An oil outlet end of the oil return pipe is connected with an oil collecting tank. A pressure switch, a pressure transmitter and a pressure gauge are connected to each signal pipe in series, a manual valve and a remotecontrol valve which are connected in parallel are further arranged on each signal pipe, and the remote control valves are connected with DCS through signal wires. The oil pressure online monitoring and testing system can effectively monitor the oil pressure of power equipment, is high in precision, and can be widely applied to the technical field of oil pressure online monitoring systems in powerplant equipment.

Description

technical field [0001] The invention relates to the field of an oil pressure online monitoring system in power plant equipment, in particular to an oil pressure online monitoring and testing system. Background technique [0002] The lubricating oil of the rotating part of important mechanical equipment and the hydraulic oil of the driving part must ensure continuous and reliable operation, and the oil pressure main pipe is connected to the online monitoring and testing device through this pressure pipe to facilitate real-time monitoring and periodic testing. For the 300,000 units in the thermal power plant, the current oil pressure signal pipe is connected to the monitoring and testing device, and the segmental test is realized through internal orifices of different sizes. The diameter of the orifice is less than 0.8mm, especially The orifice of the driving hydraulic oil is only 0.05mm. Once the foreign matter in the oil is blocked, it will cause the malfunction of the prote...
