Description

Flow meter per km.

Utility model belongs to test traffic mileage technical field.

The kilometer flowmeter is mainly used on the motor vehicles.Other motor vehicle such as automobile, tractor is installed the kilometer table now, a read rate, and the distance that accumulative total is travelled, function is simple.

The kilometer flowmeter is contained on the motor vehicle, can read the flow size of the speed of per second, distance, oil circuit that accumulative total is travelled, every kilometer oil consumption what, can make the driver select best fuel feeding position.

The kilometer flowmeter is on the basis of kilometer table, and the multi pack flowmeter by certain physical construction, can directly indicate kilometer oil consumption how many values.Shown in Figure 1, kilometer flowmeter dial plate.Last figure is a front elevation, and figure below is following view.The horizontal read number window is a speed disc, and reading value from left to right increases gradually, and the bottom is the kilometer reading, and vertically the reading window is the flow dish, and reading increases gradually from the bottom up, and two square frames in top are two maximum oil position pearls, observe whether to be filled with steam bubble.The circular arc window is hundred kilometers oil consumption dishes, and pointer can directly be read numerical value, outside kilometer table line and two oil pipes of connecting of kilometer flowmeter.Reduced pipe enlarged drawing shown in Figure 2.Fig. 3 testing pressure head difference size connection layout.Fig. 2 is different to be loaded in Fig. 3 machinery through pipe.Fig. 4 instrument structure is indicated the structure and the contact of all parts.Fig. 5 pointer front elevation, left view.

The kilometer meter adopts kilometer table principle now, inserts logical magnetic force dish by the table line and attracts to go up dish indication speed, and the table line gear is by gear train, and revolution counter changes the needle dial indication into horizontal window reading.

Flowmeter adopts Wen Deli flowmeter principle to make.Adorning one section section in oil feed line diminishes gradually and recovers the change of original section reduced pipe Fig. 2 along with flow gradually, the corresponding change of head difference of reduced pipe inlet section and throat's section.Utilize pressure gap, obtain the flow size.

The head difference size is measured with manograph.As Fig. 3 manograph (1) and reduced pipe (4), peak level pearl (5) is handled steam bubble machine (2) and connects.Connect a tubule respectively at the reduced pipe inlet end, two tubules insert manograph.Manograph is made with soft material (laterally flexible, vertically constant), centrally is divided into two halves with hard material (3), and liquid can not circulate.Hard material connects lever (6).

When reduced pipe had liquid flow, liquid not necessarily was full of in the manograph and whole pipe.By observing the steam bubble situation of the most significant digit globule, active process steam bubble machine, the work eliminating steam bubble of inspiration, extrusion.Handle the steam bubble machine valve of two unidirectional conductings is housed.(the valve conducting direction is from big one of a little sensing manograph pressure of manograph pressure) inspiration, extrude and constantly enter liquid, all steam bubbles are disposed.When the side pressure device was worked, owing to handle the unidirectional conducting of steam bubble machine, the liquid that can not that manograph pressure is big entered in the little survey of pressure.

When reduced pipe has liquid flow, produce pressure difference as Fig. 4 manograph (1) two ends, central hard material (3) is subjected to the effect of power.Hard material connects lever (6) one ends, and the lever other end is made with metallic iron, and a winding the end of a thread is adorned with insulator in the top, and there is wiring point (12) position of correspondence convenient to both.Connector lug connects one side motor just to be changeed, and connects the counter-rotating of another side motor.Motor (15) drives magnet (14) and moves by belt (7) along straight-line groove (16).Do not have when stressed at hard material, magnet is at upper/lower positions, with adjusting magnet (11) trimming moment, makes in the middle of connector lug is positioned at.After hard material is stressed, connector lug (13) the deflection left side, motor just changes, and magnet upwards slides, and increases moment, up to balance.Cut off the electricity supply after the balance, point out the pressure head extent.Magnet slides into the extreme higher position, in order to prevent to burn out motor, shields with projecting point (18), and magnet operates in projecting point, can cut off the electricity supply automatically.Flowmeter flow size equals the head difference square root and takes advantage of a constant in the literary virtue.The size indication of flow is handed over a bit with belt drive straight line pole and curve rail (17) at motor, and this point indicates flow by transverse bar (8).

Speed connects longitudinal rod (9) by speed disc drive belt and indicates velocity amplitude.The kilometer oil consumption is the ratio of flow and speed.Speed is positioned at transverse axis, and flow is positioned at the longitudinal axis, and it is the kilometer fuel consumption values of fixing that the intersection point of diaxon (10) points to a position with the true origin on line of diaxon.Pointer Fig. 5 rotation axis is contained in the diaxon true origin, and sliding tray slides on intersection point, and pointer is directly read a kilometer fuel consumption values like this.Consider that instrument intersection point in service can overlap with initial point; Pointer arbitrarily points to a side, and pointer is contained in a retracing spring that elasticity coefficient is very little, points to infinitely great when instrument stops.When not having flow to have only speed, it is a dead-centre position that pointer rotates, and therefore sliding tray begins suitably to strengthen the existence that the dead point is avoided on some Fig. 5 left side just.Motor vehicle is nonsensical in the kilometer of the indication in particular cases oil consumption of low speed, low throttle, thus processing pointer sliding tray adds on a large scale from initial point to the speed window or the flow window 1/10th in.

The processing reduced pipe: minimum diameter is not less than 0.5 millimeter, guarantees that fuel feeding is not subjected to the influence of impurity.Because the vehicle size difference is very big, reduced pipe produces the pressure difference scope 0.1-600 millimeter of water.Manograph is made with light and thin material.The hard material area is along with reduced pipe produces the decision of maximum pressure difference in the middle of the manograph, and the acting force that it produced restrains between 120 grams 5.Require the maximum resistance of manograph not surpass 0.5 gram, the maximum resistance of lever square 0.5 gram centimeter.

The kilometer flowmeter becomes the epiphase ratio with kilometer, and more perfect function can directly be read a kilometer fuel consumption values, and the driver can select optimal economic for by the position, can economize on oil like this.And can check the oil circuit situation, whether engine power performance work is normal.
