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、熱水高壓清洗機的基本結構和工作流程：

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

熱水高壓清洗機的基本結構簡單來說就是冷水高壓清洗機加一個可以對高壓水加熱的鍋爐或電熱管，高壓水經過加熱盤管加熱到所需要工作的溫度，再經軟管輸送到高壓噴嘴的部位，熱水高壓清洗機噴嘴把高壓低流速的水轉變為低壓高流速的射流，正向或切向沖擊被清洗物體的外表面，加熱后的水作為一種動力和導熱介質，對一些重油污物體環境清洗的效果是非常好的，而且其效率也是很高的。熱水高壓清洗機非常適合對油污、油垢的處理工作。比如，我們常見的對乳化液、壓縮機、液壓支架、液壓油缸的油污的清洗。

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、熱水高壓清洗機如何清洗呢？

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

清洗前所需準備：

Preparation before cleaning:

用來除垢的液體，其它除垢液體也行。熱水高壓清洗機一般可用鹽酸和水，比例為1：3，也可根據情況適當行進增減（主要考慮的是清洗的速度）。

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).

一個用來容納鹽酸水的容器，熱水高壓清洗機其大小主要考慮能夠供有足夠的水進行循環使用即可。

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.

將噴頭卸下來（這樣出來的水不會有較大壓力，鹽酸水不會濺到其它物體上）。

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

將放入鹽酸的容器引出一條水管，熱水高壓清洗機供給機器進水（此時供入設備的水沒有水壓，如開機后很長時間水不能從手持槍前端出來，即有可能是進水壓力不夠，應將容器置高或先將設備自身的水箱內先灌滿鹽酸水再開機），開機不會立即出水，因為設備及管件內部有空氣，水還沒有進入到各個部位，等待前端出水。熱水高壓清洗機將手持槍噴口對準容器內，讓槍噴口出來的鹽酸水再流入容器內，這樣進行循環的清洗即可，待看見出來的水帶有一些銹水，即為鹽酸在金屬內部有了效果，如出來的鹽酸水太臟了應進行更換，再次進行清洗。

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.
