The hot water cleaning machine is equipped with a heating device that uses a combustion cylinder or an electric heating device to heat the water. A hot water high-pressure cleaning machine with a pressure of over 500bar refers to a cleaning device that uses a high-pressure water conversion device (usually referred to as a high-pressure plunger pump) to pressurize water several times, causing it to reach a pressure of hundreds of atmospheres or more. Then, it is converted into a high-speed "water jet" through a specially made spraying device with small apertures. The speed of the "water jet" in the hot water high-pressure cleaning machine is generally more than twice the Mach number, and it has huge impact energy, which can complete different types of cleaning and cleaning tasks.

一、热水高压清洗机的基本结构和工作流程：

1、 The basic structure and workflow of a hot water high-pressure cleaning machine:

热水高压清洗机的基本结构简单来说就是冷水高压清洗机加一个可以对高压水加热的锅炉或电热管，高压水经过加热盘管加热到所需要工作的温度，再经软管输送到高压喷嘴的部位，热水高压清洗机喷嘴把高压低流速的水转变为低压高流速的射流，正向或切向冲击被清洗物体的外表面，加热后的水作为一种动力和导热介质，对一些重油污物体环境清洗的效果是非常好的，而且其效率也是很高的。热水高压清洗机非常适合对油污、油垢的处理工作。比如，我们常见的对乳化液、压缩机、液压支架、液压油缸的油污的清洗。

The basic structure of a hot water high-pressure cleaning machine is simply to add a boiler or electric heating tube to the cold water high-pressure cleaning machine that can heat high-pressure water. The high-pressure water is heated to the required working temperature through a heating coil, and then transported to the high-pressure nozzle through a hose. The nozzle of the hot water high-pressure cleaning machine converts high-pressure and low flow rate water into a low-pressure and high flow rate jet, which impacts the outer surface of the cleaned object in a positive or tangential direction, The heated water, as a power and thermal medium, has a very good cleaning effect on some heavy oil and dirt environments, and its efficiency is also very high. The hot water high-pressure cleaning machine is very suitable for the treatment of oil and dirt. For example, we commonly clean oil stains from emulsions, compressors, hydraulic supports, and hydraulic cylinders.

二、热水高压清洗机如何清洗呢？

2、 How to clean a hot water high-pressure cleaning machine?

清洗前所需准备：

Preparation before cleaning:

用来除垢的液体，其它除垢液体也行。热水高压清洗机一般可用盐酸和水，比例为1：3，也可根据情况适当行进增减（主要考虑的是清洗的速度）。

A liquid used for descaling, and other descaling liquids are also suitable. Hot water high-pressure cleaning machines can generally use hydrochloric acid and water in a ratio of 1:3, and can also be increased or decreased according to the situation (mainly considering the cleaning speed).

一个用来容纳盐酸水的容器，热水高压清洗机其大小主要考虑能够供有足够的水进行循环使用即可。

A container used to hold hydrochloric acid water, the size of the hot water high-pressure cleaning machine is mainly considered to be able to provide enough water for circulation.

将喷头卸下来（这样出来的水不会有较大压力，盐酸水不会溅到其它物体上）。

Remove the nozzle (so that the water coming out will not have significant pressure and hydrochloric acid water will not splash onto other objects).

将放入盐酸的容器引出一条水管，热水高压清洗机供给机器进水（此时供入设备的水没有水压，如开机后很长时间水不能从手持枪前端出来，即有可能是进水压力不够，应将容器置高或先将设备自身的水箱内先灌满盐酸水再开机），开机不会立即出水，因为设备及管件内部有空气，水还没有进入到各个部位，等待前端出水。热水高压清洗机将手持枪喷口对准容器内，让枪喷口出来的盐酸水再流入容器内，这样进行循环的清洗即可，待看见出来的水带有一些锈水，即为盐酸在金属内部有了效果，如出来的盐酸水太脏了应进行更换，再次进行清洗。

Introduce a water pipe from the container containing hydrochloric acid, and the hot water high-pressure cleaning machine will supply the machine with water (at this time, the water supplied to the equipment does not have water pressure. If the water cannot come out from the front end of the handheld gun for a long time after starting up, it is possible that the water inlet pressure is not enough. The container should be raised or the equipment's own water tank should be filled with hydrochloric acid water first before starting up). The water will not immediately flow out when starting up, because there is air inside the equipment and pipe fittings, The water has not yet entered various parts, waiting for the front end to come out. The hot water high-pressure cleaning machine aims the handheld gun nozzle into the container, allowing the hydrochloric acid water from the gun nozzle to flow back into the container. This cycle of cleaning can be carried out. When some rust water is seen in the water, it indicates that hydrochloric acid has an effect on the metal interior. If the hydrochloric acid water is too dirty, it should be replaced and cleaned again.
