高压清洗机不能加热是因为什么原因？What is the reason why the high-pressure washer cannot be heated?

高压清洗机可分为冷水、热水和蒸汽三种类型，冷水式清洗机只能用冷水清洗，而热水式的清洗机既可以用热水清洗，也可以用冷水清洗，是两用型的。
High-pressure washing machines can be divided into three types: cold water, hot water and steam. Cold water washing machines can only be cleaned with cold water, while hot water washing machines can be cleaned with hot water or cold water, which is dual-use.

热水高压清洗机在去除油污方面有特殊的优势，适用于食品加工业、饲料加工企业、化工行业等企业的设备和油污管道的清洗。在设备长时间运行之后每一环节都有可能会呈现毛病，然后导致热水高压清洗机不能够正常加热水温。这种情况下该怎么排查毛病呢？

Hot water high-pressure cleaning machine has special advantages in removing oil pollution, and is suitable for cleaning equipment and oil pollution pipelines of food processing industry, feed processing enterprises, chemical industry and other enterprises. After the equipment has been running for a long time, every link may have problems, and then the hot water high-pressure washer can not normally heat the water temperature. How to troubleshoot the problem in this case?

我们首先需要查看热水高压清洗机加热器内的燃油液面，如果燃油液面低于标准值，那么将于与火花无法接触。

First, we need to check the fuel level in the heater of the hot water high-pressure washer. If the fuel level is lower than the standard value, it will be impossible to contact the spark.

还需要查看排气风扇旋转方向是否正确，如果是旋转方向不正确可以把电源线任意对换两根再接。其次我们要检查热水高压清洗机的加热器的点火电极是否正常，两个点火电极之间的间隙必须要合适，如果电极有烧毁现象则需要更换新的，点火变压器的工作电压同样重要，我们应该检测其是否在正常的范围内。
It is also necessary to check whether the rotation direction of the exhaust fan is correct. If the rotation direction is incorrect, you can exchange two power cables at will and connect them again. Secondly, we should check whether the ignition electrode of the heater of the hot water high-pressure washer is normal. The gap between the two ignition electrodes must be appropriate. If the electrode is burnt, it needs to be replaced. The working voltage of the ignition transformer is also important. We should check whether it is within the normal range.

热水高压清洗机中的温度调节器的作用是调节、控制加热器出口处的水温，当旋钮在位置1时，加热器总是关闭，所以才会出现不能加热的情况，这是需要重新调节。热水高压清洗机的加热器中装有低水位保护系统，如果其内部缺少足够的水，低水位保护系统就会阻止锅炉点燃和加热水温，所以这也是热水高压清洗机不能加热的原因之一。

The function of the temperature regulator in the hot water high-pressure washer is to regulate and control the water temperature at the outlet of the heater. When the knob is at position 1, the heater is always turned off, so it can not be heated, which needs to be readjusted. The heater of the hot water high-pressure washer is equipped with a low water level protection system. If it lacks enough water inside, the low water level protection system will prevent the boiler from igniting and heating the water temperature, so this is also one of the reasons why the hot water high-pressure washer cannot heat.
