Steel support axial force servo hydraulic system is a complete set of safety solutions for foundation pit engineering which has the characteristics of 24 hours real-time monitoring, low pressure automatic compensation, high pressure automatic alarm and multiple security protection. Applicable to the project of strictly controlling the deformation of foundation pit.
This system is composed of several distributed numerical control hydraulic pump stations. Every NC hydraulic pump station is controlled independently and not affected each other. Every NC hydraulic pump station has 4 independent oil passage, which can realize the independent control of 4 hydraulic cylinders. CNC oil pump built-in pressure and displacement sensor, achieves the dual control of pressure and stroke.
NC hydraulic pump station is small in size, light in weight and convenient in layout. Distributed structure greatly shortens the hose connection between pump station and support equipment, system assembly is more convenient and quick.
Self locking and alarming for abnormal states, such as low pressure automatic compensation, high pressure, etc. provide full range of multiple security protection including dual control of pressure and displacement.
NC pump stations are independent from each other, the relative concentration of large pumping station, to avoid oil leakage or explosion due to a single tube and the impact of other oil, while avoiding the pump head hydraulic power failure caused the paralysis of the whole system dilemma, the greatest degree of dispersion of systemic risk, improve the reliability of the whole system.
Monitoring data can be outputted through the electronic control system network, while equipped with dedicated data acquisition industrial computer monitoring, to achieve 24 hours online monitoring.
Lifting data can be imported into the equipment database at once. Lifting results are automatically recorded in the database, which can be printed and downloaded.
