Description
Technical field
The utility model relates to oil field service machine auxiliary equipment, the electronic liquid-supplying system of specifically a kind of oil field service machine steering hardware.
Background technology
The oil field service machine is big from heavy lift, cornering resistance is also big, by manpower driving device steering hardware, is difficult to overcome the propons cornering resistance, so extensively adopt hydraulic power-assist steering system to guarantee the operability of Vehicular turn, reduce the labour intensity of driver driving vehicle to greatest extent.The hydraulic power-assisted steering system of service machine produces high pressure oil stream by driven by engine steering gear oil pump, and the power-assisted fluid cylinder that utilizes high pressure oil stream to drive in the steering hardware carries out work; Turn to distributing valve by mechanical mechanism controls during driver's steering wheel rotation, distributing valve control enters the oily flow path direction powered vehicle front-wheel steering of power-assisted fluid cylinder.
At present, the steering hydraulic force aid system of service machine comes with some shortcomings: the one, no matter whether need power steering, hydraulic booster system is in running order always, and hydraulic oil pump is to drive by driving engine, energy consumption is higher; The 2nd, when the low speed of a motor vehicle turned to greatly, engine speed was not high, and the discharge capacity of steering pump output is lower, this moment the power steering poor effect, there is potential safety hazard in operating difficulties.
The utility model content
The purpose of this utility model is: the electronic liquid-supplying system that a kind of service machine steering hardware is provided, adopt the individual drive mode to work, liquid supply rate and pressure all can be regulated as required, start when needing to use, stop when not needing to use, be particularly suitable for being applied to the power steering that electricity drives the class service machine.
The technical solution adopted in the utility model is: the electronic liquid-supplying system of service machine steering hardware, mainly by inverter, alternating current dynamo, hydraulic oil pump, fuel tank, by pass valve and turn to distributing valve to form, it is characterized in that: the mouth of inverter connects alternating current dynamo by lead, alternating current dynamo connects hydraulic oil pump by coupler, the hydraulic oil inlet of hydraulic oil pump links to each other with fuel tank by hydraulic power line, the hydraulic oil outlet of hydraulic oil pump is connected with high pressure line, high pressure line connects the distributing valve that turns to of service machine steering hardware, turns to the outlet of distributing valve to have pipeline to connect the service machine steering hardware; To the high pressure line that turns between the distributing valve threeway is arranged at hydraulic oil pump, connect a pipeline by threeway, but be connected with the by pass valve of pressure regulation on this pipeline, the outgate of by pass valve has pipeline to link to each other with fuel tank.
The beneficial effects of the utility model: the electronic liquid-supplying system of the utility model service machine steering hardware, after realization works alone, the pulsation-free power steering can when turning to greatly, the low speed of a motor vehicle be provided, effectively alleviate the strength of pilot control bearing circle, reduce the frequent steering dish of chaufeur and the driving fatigue that causes.Adopt the individual drive mode to work, feed flow discharge capacity and pressure all can be regulated as required, start when needing to use, and can stop when not needing to use, and are particularly suitable for being applied to the power steering that electricity drives the class service machine.Simple in structure, install easily, maintaining is convenient, low price.
Description of drawings
Fig. 1 is the electronic liquid-supplying system structural representation of the utility model service machine steering hardware.
Among the figure, the 1-inverter, the 2-alternating current dynamo, the 3-hydraulic oil pump, the 4-fuel tank, the 5-by pass valve, 6-turns to distributing valve.
The specific embodiment
Embodiment 1: the electronic liquid-supplying system with a service machine steering hardware is an example, and the utility model is described in further detail.
Consult Fig. 1.The electronic liquid-supplying system of the utility model service machine steering hardware is mainly by inverter 1, alternating current dynamo 2, hydraulic oil pump 3, fuel tank 4, by pass valve 5 with turn to distributing valve 6 to form.
The mouth of inverter 1 connects alternating current dynamo 2 by lead, alternating current dynamo 2 connects hydraulic oil pump 3 by coupler, the hydraulic oil inlet of hydraulic oil pump 3 links to each other with fuel tank 4 by hydraulic power line, the hydraulic oil outlet of hydraulic oil pump 3 is connected with high pressure line, what high pressure line connected the service machine steering hardware turns to distributing valve 6, turns to the outlet of distributing valve 6 to have pipeline to connect the service machine steering hardware; To the high pressure line that turns between the distributing valve 6 threeway is arranged at hydraulic oil pump 3, connect a pipeline by threeway, but be connected with the by pass valve 5 of pressure regulation on this pipeline, the outgate of by pass valve 5 has pipeline to link to each other with fuel tank 4.
It is the function of 380V alternating current that inverter 1 has the 480V Direct current treatment, and by changing the 380V ac frequency, the height of control alternating current dynamo 2 rotating speeds is with modulated pressure oil pump 3 output discharge capacities.Mix up the frequency of inverter (frequency-variable controller) 1, alternating current dynamo 2 drives hydraulic oil pump 3 runnings by coupler, by regulating by pass valve 5 control system liquid working pressures between 4～10MPa, guarantees the power steering that service machine turns to provides reliable and stable.
