1 High pressure pump

高壓清洗機的核心是高壓泵，它們處于不可替代的位置高壓泵用于增加水壓，將高壓水輸送到高壓水槍或噴嘴這種泵可以移動或固定容積式柱塞泵是保證給定泵速下流量恒定的常用泵

The core of high-pressure cleaning machines is high-pressure pumps, which are in an irreplaceable position. High pressure pumps are used to increase water pressure and deliver high-pressure water to high-pressure water guns or nozzles. These pumps can be moved or fixed. Positive displacement plunger pumps are commonly used to ensure a constant flow rate at a given pump speed

高壓清洗機自誕生以來，一直面臨著許多故障，但一般90%的故障不是由泵引起的常見的故障是由部件或部件（如噴嘴）磨損引起的水泵進水不足是水泵早期故障的主要原因不合適的進氣管不能使足夠的水進入泵內，造成氣蝕，氣蝕會導致混入水中的氣體發生小爆炸，造成超壓損壞和活塞表面磨損

Since its inception, high-pressure cleaning machines have been facing many failures, but generally 90% of the failures are not caused by the pump. The common failures are caused by the wear of components or components (such as nozzles), and insufficient water intake is the main cause of early water pump failures. Inappropriate intake pipes cannot allow enough water to enter the pump, causing cavitation, which can cause small explosions of gas mixed in the water, causing overpressure damage and piston surface wear

2海豹

2 seals

大多數泵的設計都包括一個水循環系統，用于潤滑密封件，以防止因磨損而泄漏當磨損或壓力降超過時，應更換相關的密封件有時新泵的摩擦阻力更大，直到密封件和活塞之間的配合更合適為止

Most pump designs include a water circulation system to lubricate the seals to prevent leakage due to wear. When wear or pressure drop exceeds, the relevant seals should be replaced. Sometimes, the friction resistance of the new pump is greater until the fit between the seals and the piston is more suitable

3曲軸箱

3 crankcase

曲軸箱故障很少如果保養正常，應在初次使用50小時后更換潤滑油，然后每500小時或每年更換一次，直到潤滑油乳化為止，這通常是由于溫度或油封泄漏引起的老化和變質引起的，如果軸箱中的油塞沒有加滿或油封被吸到B中，潤滑油就會發熱Y真空

If the maintenance of the crankcase is normal, the lubricating oil should be replaced after the first 50 hours of use, and then every 500 hours or every year until the lubricating oil emulsifies. This is usually caused by aging and deterioration caused by temperature or oil seal leakage. If the oil plug in the crankcase is not filled or the oil seal is sucked into B, the lubricating oil will generate heat and vacuum

4過濾元件

4 filtering elements

好的入口過濾器是保護設備的廉價方法灰塵、碎屑和沙子很容易損壞閥門和活塞解決方法是使用60-100目濾布和適合水流的尺寸，并確保定期檢查

A good inlet filter is an inexpensive way to protect equipment. Dust, debris, and sand can easily damage valves and pistons. The solution is to use a 60-100 mesh filter cloth and a size suitable for water flow, and ensure regular inspection

5減壓閥

5 Pressure reducing valve

只有當設備對高壓水敏感時，有時由于高壓水，清洗液吸入口不能工作

Only when the equipment is sensitive to high-pressure water, sometimes the cleaning fluid suction port cannot work due to high-pressure water

6壓力表

6 Pressure gauge

高壓清洗機應設置此表以顯示壓力變化壓力表的校準范圍至少比高壓清洗機的大工作壓力高50%當壓力波動較大時，應設置壓力調節器以準確顯示壓力讀數壓力表提供一個重要的警告條件，用于監測噴嘴磨損和密封失效導致的減少，并避免將來更昂貴的維護

The high-pressure cleaning machine should be equipped with this gauge to display pressure changes. The calibration range of the pressure gauge should be at least 50% higher than the large working pressure of the high-pressure cleaning machine. When the pressure fluctuation is large, a pressure regulator should be installed to accurately display the pressure reading. The pressure gauge provides an important warning condition to monitor the reduction caused by nozzle wear and seal failure, and to avoid more expensive maintenance in the future

7泄壓閥（調壓閥）

7 Pressure relief valve (pressure regulating valve)

這是清洗機的主要安全部件，它保證了噴槍的自由使用和水通過系統的流動如果噴槍沒有完全釋放，壓力將繼續上升直到發動機（汽油發動機或馬達）被損壞或泵、軟管或噴槍損壞安全閥將全部或部分水流回水箱或進水口，以防止壓力上升

This is the main safety component of the cleaning machine, which ensures the free use of the spray gun and the flow of water through the system. If the spray gun is not fully released, the pressure will continue to rise until the engine (gasoline engine or motor) is damaged or the pump, hose, or spray gun is damaged. The safety valve will completely or partially flow back to the water tank or inlet to prevent pressure from rising

調壓閥分為調零閥和非調零閥，目前大部分采用零回調壓閥，控制形式分為手動控制和氣動控制

Pressure regulating valves are divided into zero regulating valves and non zero regulating valves. Currently, most of them use zero return pressure valves, and the control forms are divided into manual control and pneumatic control

8安全閥

8 Safety valve

當壓力超過設定的報警壓力時，泄壓閥放水，爆破片是設計中的薄弱環節，當壓力超過設計壓力時爆破片破裂

When the pressure exceeds the set alarm pressure, the relief valve releases water, and the bursting disc is a weak link in the design. When the pressure exceeds the design pressure, the bursting disc ruptures

安全閥安裝在泵的排放端閥內有彈簧和閥組機構氣門芯通常由彈簧預設在角，當高壓泵的壓力超過預定值時，氣門打開

The safety valve is installed in the discharge end of the pump, with a spring and valve group mechanism. The valve core is usually preset at the angle by the spring. When the pressure of the high-pressure pump exceeds the predetermined value, the valve opens

9高壓槍

9 High pressure gun

高壓槍是一種以觸發式球閥為核心的簡單機械，在水流的作用下，閥球保持在關閉位置或向前位置，或關閉水通過槍進入噴嘴的通道，當扳機被拉動時，它將活塞推到閥珠上，迫使閥珠離開閥座并打開在水進入噴嘴的過程中，當釋放觸發器時，閥珠在彈簧的作用下回到閥座上，關閉通道當參數允許時，噴槍應使操作人員感到舒適

The high-pressure gun is a Simple machine with the trigger ball valve as the core. Under the action of water flow, the valve ball is kept in the closed position or the forward position, or the channel of water entering the nozzle through the gun is closed. When the trigger is pulled, it pushes the piston onto the valve ball, forcing the valve ball to leave the valve seat and open during the process of water entering the nozzle. When the trigger is released, the valve ball returns to the valve seat under the action of the spring, and closes the channel. When the parameters allow, The spray gun should make the operator feel comfortable

高壓槍通過高壓軟管總成連接到高壓泵的排放端高壓水槍是一種常見的執行機構，也是操作頻繁的部件，根據排放壓力的控制閥類型，可以進一步定義高壓水槍：當閥門關閉時，如果高壓水排放到大氣中，則為溢流高壓水槍；當閥門是關閉的，它是一個關閉高壓槍

The high-pressure gun is connected to the discharge end of the high-pressure pump through a high-pressure hose assembly. The high-pressure water gun is a common actuator and a frequently operated component. Based on the type of control valve for the discharge pressure, the high-pressure water gun can be further defined: when the valve is closed and high-pressure water is discharged into the atmosphere, it is an overflow high-pressure water gun; When the valve is closed, it is a closed high-pressure gun

10高壓噴嘴

10 High pressure nozzle

高壓噴嘴是高壓清洗機的一個部件，內置一個或多個噴嘴高壓噴嘴限制水的流動面積，加速流速，形成所需的噴射形狀它影響壓力和效率噴射面積小意味著壓力更大這就是為什么旋轉噴頭越來越流行的原因事實上，它們不會增加壓力但它們以移動的方式使用零注入角，以比使用零注入角更快地覆蓋更大的區域

A high-pressure nozzle is a component of a high-pressure cleaning machine, which is equipped with one or more built-in nozzles. The high-pressure nozzle limits the flow area of water, accelerates the flow rate, and forms the desired spray shape, which affects pressure and efficiency. A small spray area means greater pressure, which is why rotating nozzles are becoming increasingly popular. In fact, they do not increase pressure, but they use zero injection angle in a mobile manner, Covering larger areas faster than using zero injection angle

11高壓管

11 High pressure pipe

高壓管道通常由軟管制造商提供，以確保爆破壓力為工作壓力的4倍

High pressure pipelines are usually provided by hose manufacturers to ensure a burst pressure of 4 times the working pressure
