1 High pressure pump

高压清洗机的核心是高压泵，它们处于不可替代的位置高压泵用于增加水压，将高压水输送到高压水枪或喷嘴这种泵可以移动或固定容积式柱塞泵是保证给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

高压清洗机自诞生以来，一直面临着许多故障，但一般90%的故障不是由泵引起的常见的故障是由部件或部件（如喷嘴）磨损引起的水泵进水不足是水泵早期故障的主要原因不合适的进气管不能使足够的水进入泵内，造成气蚀，气蚀会导致混入水中的气体发生小爆炸，造成超压损坏和活塞表面磨损

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

大多数泵的设计都包括一个水循环系统，用于润滑密封件，以防止因磨损而泄漏当磨损或压力降超过时，应更换相关的密封件有时新泵的摩擦阻力更大，直到密封件和活塞之间的配合更合适为止

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曲轴箱

3 crankcase

曲轴箱故障很少如果保养正常，应在初次使用50小时后更换润滑油，然后每500小时或每年更换一次，直到润滑油乳化为止，这通常是由于温度或油封泄漏引起的老化和变质引起的，如果轴箱中的油塞没有加满或油封被吸到叠中，润滑油会发热驰真空

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过滤元件

4 filtering elements

好的入口过滤器是保护设备的廉价方法灰尘、碎屑和沙子很容易损坏阀门和活塞方法是使用60-100目滤布和适合水流的尺寸，并确保定期检查

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减压阀

5 Pressure reducing valve

只有当设备对高压水敏感时，有时由于高压水，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压力表

6 Pressure gauge

高压清洗机应设置此表以显示压力变化压力表的校准范围少比高压清洗机的大工作压力高50%当压力波动较大时，应设置压力调节器以准确显示压力读数压力表提供一个重要的警告条件，用于监测喷嘴磨损和密封失效导致的减少，并避免将来更昂贵的维护

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泄压阀（调压阀）

7 Pressure relief valve (pressure regulating valve)

这是清洗机的主要部件，它保证了喷枪的自由使用和水通过系统的流动如果喷枪没有完全释放，压力将继续上升直到发动机（汽油发动机或马达）被损坏或泵、软管或喷枪损坏阀将全部或部分水流回水箱或进水口，以防止压力上升

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

调压阀分为调零阀和非调零阀，目前大部分采用零回调压阀，控制形式分为手动控制和气动控制

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阀

8 Safety valve

当压力超过设定的报警压力时，泄压阀放水，爆破片是设计中的薄弱环节，当压力超过设计压力时爆破片破裂

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

阀安装在泵的排放端阀内有弹簧和阀组机构气门芯通常由弹簧预设在角，当高压泵的压力超过预定值时，气门打开

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高压枪

9 High pressure gun

高压枪是一种以触发式球阀为核心的简单机械，在水流的作用下，阀球保持在关闭位置或向前位置，或关闭水通过枪进入喷嘴的通道，当扳机被拉动时，它将活塞推到阀珠上，迫使阀珠离开阀座并打开在水进入喷嘴的过程中，当释放触发器时，阀珠在弹簧的作用下回到阀座上，关闭通道当参数允许时，喷枪应使操作人员感到舒适

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

高压枪通过高压软管总成连接到高压泵的排放端高压水枪是一种常见的执行机构，也是操作频繁的部件，根据排放压力的控制阀类型，可以进一步定义高压水枪：当阀门关闭时，如果高压水排放到大气中，则为溢流高压水枪；当阀门是关闭的，它是一个关闭高压枪

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高压喷嘴

10 High pressure nozzle

高压喷嘴是高压清洗机的一个部件，内置一个或多个喷嘴高压喷嘴限制水的流动面积，加速流速，形成所需的喷射形状它影响压力和效率喷射面积小意味着压力更大这是为什么旋转喷头越来越流行的原因事实上，它们不会增加压力但它们以移动的方式使用零注入角，以比使用零注入角更快地覆盖更大的区域

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高压管

11 High pressure pipe

高压管道通常由软管制造商提供，以确保爆破压力为工作压力的4倍

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