Hydraulic station oil pump oil feeding system

Abstract

The invention relates to a hydraulic station oil pump oil feeding system. The bottom of an oil tank is communicated and fixedly provided with a rigid oil tank oil inlet pipe; the outlet of the oil tank oil inlet pipe is connected and communicated with a hydraulic pump via an oil pump connecting pipe; the inlet of the oil tank oil inlet pipe is provided with a V-shaped joint; a valve rod is fixedly arranged on the top of the oil tank via a supporting seat and a supporting plate arranged above the supporting seat; the tail end of the valve rod is positioned above the outlet of the V-shaped joint. A ball valve is replaced in a way that the valve rod is cooperated with the V-shaped joint to control the oil to be filled in or discharged; the position is changed to the top of the oil tank from the bottom of the oil tank, so that the installation technology is simplified, and convenience is brought for overhauling; meanwhile, the outlet of the oil tank oil inlet pipe is connected with the hydraulic pump via a hose to omit a compensator; flexible connection is simple to install on the manufacture technology, a vibration source can be isolated when equipment is operated, and noise pollution is reduced; according to the integral structure, the compensator and the ball valve are omitted, the practicality is stronger, and a pipeline is more optimal.

Description

technical field [0001] The invention relates to an oil inlet system, in particular to an oil inlet system for an oil pump of a hydraulic station. Background technique [0002] The hydraulic station is a hydraulic source device consisting of a hydraulic pump, a driving motor, an oil tank, a relief valve, etc., or a hydraulic device including a control valve. Supply oil according to the flow direction, pressure and flow required by the driving device, connect the hydraulic station with the driving device (oil cylinder or motor) with oil pipes, and the hydraulic system can realize various specified actions. [0003] In the prior art, the hydraulic station adopts two-stage drive, two motors and a hydraulic pump. When the oil pump is upside down or placed down, the oil pump inlet pipe will use the shock absorber throat and the ball valve, but this structure has the following defects: 1. Equipment work When the shock absorber throat produces turbulent flow, the oil inlet is not s...

Problems solved by technology

[0003] In the prior art, the hydraulic station adopts two-stage drive, two motors and a hydraulic pump. When the oil pump is upside down or placed down, the oil pump inlet pipe will use the shock absorber throat and ball valve, but this structure has the following defects: 1. The equipment works When the shock absorber throat produces turbulence, the oil inlet is not smooth and the noise is increased; 2. The ball valve switch is at the bottom of the fuel tank, and the space for equipment maintenance is small, and the operation is inconvenient; 3. Since the hard pipe is formed by multi-stage welding, the weld seam There is an oil leak hazard in the location
