Abstract

The utility model discloses a double fuel engine fuel oil injection volume digital control executing apparatus which comprises a housing, a stepping motor, a potentiometer, wire tread insert parts, a flexible coupling and a guidance key. The stepping motor and the potentiometer are equipped in the housing respectively. The flexible coupling is connected with the right terminal shaft of the potentiometer and the left terminal shaft of the stepping motor. The right terminal shaft of the stepping motor is connected and cooperated tightly with a wire rod. The wire tread insert parts are engaged with the wire rod by a wire tread insert. The guidance key is out of the wire tread insert parts. The right terminal of the wire tread insert parts is contact with a gear rod of a fuel injection pump. The utility model can realize a direct digital control and control oil outlet volume of the fuel injection pump precisely.

Description

The digital control actuating device of duel fuel engine fuel injection amount
The utility model relates to a kind of duel fuel engine fuel injection amount control device, particularly be a kind of micro-control figure formula control actuating device that is used for diesel oil-natural gas double fuel engine diesel oil.
Following three kinds of patterns are mostly adopted in the diesel oil amount of diesel oil-natural gas double fuel engine control both at home and abroad at present:
1, by mechanical mechanism restriction diesel fuel injection pump throttle position the diesel injection amount is controlled;
2, by two electromagnet promotion oil pump ratch are installed on diesel injection pump the diesel injection amount is controlled;
3, by the displacement of DC linear motor control ratch is installed on diesel injection pump.
Above-mentioned the 1st, 2 kind of pattern only can be carried out limiting the quantity of of a certain value to the diesel injection amount, can not regulate fuel injection quantity according to load change.
Though the 3rd kind of mode can be regulated, because employing is the DC linear motor, control accuracy is relatively poor, can not realize directly digital control.
The purpose of this utility model is: provide a kind of and can change the diesel injection amount as required, arbitrarily, control accuracy is high and can directly realize the digital control actuating device of numerically controlled injecting fuel of diesel motor amount.
The utility model is such formation: it is by housing (1), stepper motor (2), potentiometer (3), silk braid assembly (4), flexible coupling (5), feather key (8) is formed, stepper motor (2), potentiometer (3) is contained in respectively in the housing (1), and by the right-hand member axle of flexible coupling (5) connection potentiometer (3) and the left end shaft of stepper motor (2), the right-hand member axle of stepper motor (2) is connected with screw mandrel (6) drive fit, silk braid assembly (4) has a feather key (8) by silk braid (7) and screw mandrel (6) engagement outside silk braid assembly (4), the right-hand member of silk braid assembly (4) contacts with the ratch (10) of Injection Pump (9).
Compared with the prior art, the utlity model has following advantage:
1, the core component of this device adopts stepper motor, can realize directly digital control;
2, because the straight-line displacement of control actuating device is changed by swing offset by screw mandrel silk braid device, and its position control accuracy is higher, thrust is big;
3, move to expected value when this device, after the stepper motor dead electricity, this device has the position memory function, and therefore, power consumpiton is lower;
4, adopt the multi-turn wire-wound potentiometer that the working state of stepper motor is detected, improved control accuracy, and can monitor the motion dynamic process of control mechanism;
5, after this device is applied to diesel oil-natural gas double-fuel electric-controlling injection system, owing to can accurately control to the diesel oil amount, and can regulate the diesel injection amount according to the working state of motor, thereby improve the control accuracy of motor and rock gas replacement rate diesel oil.
Accompanying drawing 1 is a structure principle chart of the present utility model.
Embodiment of the present utility model: stepper motor (2), potentiometer (3) are contained in respectively in the housing (1), and by the right-hand member axle of flexible coupling (5) connection potentiometer (3) and the left end shaft of stepper motor (2), the right-hand member axle of stepper motor (2) is connected with screw mandrel (6) drive fit, silk braid assembly (4) is by silk braid (7) and screw mandrel (6) engagement, one feather key (8) is arranged outside silk braid assembly (4), and the right-hand member of silk braid assembly (4) contacts with the ratch (10) of Injection Pump (9).During work, when controller necessarily instructs for stepper motor, stepper motor drives screw mandrel and turns an angle, screw mandrel drives the silk braid assembly and rotates, but because the restriction and the leading role of feather key, the silk braid assembly can't be rotated and can only move axially, thereby promote the ratch of Injection Pump, meanwhile, the potentiometer that links to each other with stepper motor detects the angle of swing of stepper motor, by calculating outgoing position is carried out the data feedback, controller sends revised instruction to stepper motor again, and then reaches the oil pump capacity purpose of accurate control Injection Pump.

Claims (1)

1, the digital control actuating device of a kind of duel fuel engine fuel injection amount, it is by housing (1), stepper motor (2), potentiometer (3), silk braid assembly (4), flexible coupling (5), feather key (8) is formed, it is characterized in that: stepper motor (2), potentiometer (3) is contained in respectively in the housing (1), and by the right-hand member axle of flexible coupling (5) connection potentiometer (3) and the left end shaft of stepper motor (2), the right-hand member axle of stepper motor (2) is connected with screw mandrel (6) drive fit, silk braid assembly (4) is by silk braid (7) and screw mandrel (6) engagement, one feather key (8) is arranged outside silk braid assembly (4), and the right-hand member of silk braid assembly (4) contacts with the ratch (10) of Injection Pump (9).
