低成本、率、以工作质量保证产品质量

叉车油表使用时间长，或更换新零件时，应及时检查、调整、修理。油表在使用过程中，经常会出现以下故障：

When forklift oil gauge is used for a long time or new parts are replaced, it should be checked, adjusted and repaired in time. During the use of the oil gauge, the following faults often occur:

1、叉车油表指针不动。

1. Forklift oil gauge pointer does not move.

无论储存多少燃油，燃油表都会读数为0，否则点火时指针不会移动。原因有：油表的供电线或油表与传感器之间的导线搭接；焊头坏、断线、铅铁坏或烧坏，导致电路不工作；燃油表后接线柱上的导线接反了。

No matter how much fuel is stored, the fuel gauge will read 0, otherwise the pointer will not move during ignition. The reasons are: the power supply line of the oil meter or the wire between the oil meter and the sensor is overlapped; The welding head is broken, the wire is broken, the lead iron is broken or burned, resulting in the circuit not working; The wires on the rear terminal of the fuel gauge are reversed.

2.叉车油表读数过高。

2. The reading of forklift oil gauge is too high.

无论储存多少油，燃油表读数为“1”或高。这是由于传感器滑块、铁线、滑块、压敏电阻接触不良或中断造成的。综上所述，无论浮子处于什么位置，线路中的阻力总是较大，并与浮子一起上升。压敏电阻的情况类似，所以添加压敏电阻时的读数始终为1或高。

No matter how much oil is stored, the fuel gauge reading is "1" or high. This is caused by poor contact or interruption of sensor slider, iron wire, slider and varistor. To sum up, no matter where the float is, the resistance in the line is always large and rises together with the float. The situation of varistors is similar, so the reading when adding varistors is always 1 or high.

3、叉车油表读数不准确。

3. The reading of forklift oil gauge is inaccurate.

通常是由于接线不良造成的。它是由开关不良或传感器可变电阻故障引起的。可以从检查接线和切换导轨入手，然后用换位比较法判断旧件是否损坏，从而决定是否需要维修。代替。

It is usually caused by poor wiring. It is caused by poor switch or sensor variable resistance failure. You can start with checking the wiring and switching guide rail, and then use the transposition comparison method to judge whether the core is damaged, so as to determine whether it needs maintenance. Replace.

济南二手叉车厂家提醒您，在此基础上，采用直径0.2mm的镍铬合金线对线材进行绝缘，烧毁压敏电阻线。仿冒时，其阻值及连接方式应与原件相同。修复完成后，可按上述方法进行检查，证明无误后才能进行修复。

Jinan used forklift manufacturer reminds you that on this basis, nickel chromium alloy wire with a diameter of 0.2mm is used to insulate the wire and burn the varistor wire. When counterfeiting, its resistance value and connection method should be the same as the original. After the repair is completed, it can be checked according to the above method and can be repaired only after it is proved to be correct.

油表线圈损坏后，可用直径0.132mm的漆包线仿制。模仿时要注意线圈的绕制方向、匝数、电阻、接法要与原线圈相同，左右线圈匝数不同，绕制方向不同，所以不能互换。维修后，还要进行上述检查。

After the oil gauge coil is damaged, it can be copied with enameled wire with a diameter of 0.132mm. When imitating, pay attention to that the winding direction, number of turns, resistance and connection method of the coil should be the same as that of the original coil. The number of turns of the left and right coils are different, and the winding direction is different, so it cannot be interchanged. After maintenance, the above inspection should also be carried out.
