Discussion of the composition and failure:
1 The heart of the washing machine is a high-pressure pump, they are in an irreplaceable position. Piston pumps are the most common. Because they are more efficient and have a longer life, pistons are usually made of ceramics and are very resistant to wear. Piston pumps are often described as A piston moves back and forth. Through a fixed seal; the plunger pump seal is mounted on the plunger. Through a smooth cylinder wall, the plunger pump usually has better initial use characteristics, but cannot operate at excessive pressure and has a short life. .
2 The capacity of the pump depends on the speed of the pump, and the pump must allow the same amount of water to enter and exit. It does not increase or decrease the flow rate like a centrifugal pump. The piston pump has a very stable water flow parameter, no matter how high the pressure is injected, the flow rate of the nozzle will cause the high pressure pump to be under pressure. Therefore, devices such as pressure relief valves are installed in the system.
3 When the piston moves backwards, water is drawn into the sealed chamber through the inlet valve, and when the piston moves forward, the water is forced to flow through the outlet valve to the outlet of the pump. Most piston pumps are double or triple. Dual piston pumps are more demanding and rigorous for system components and operators. Triple pumps are the most versatile form of high pressure cleaners due to their smoother water flow. High-speed pumps can produce less pressure loss and require less starting torque. However, it can cause faster wear, less suction, and sometimes noise and damage.
4 90% of the pressure washers are usually not because of the pump, the most common fault is caused by the wear of components or components (such as nozzle seals), the lack of water in the pump is the primary cause of the early failure of the pump, the inlet pipe Inappropriate does not allow enough water to enter the pump causing cavitation. Cavitation causes a small explosion of gas mixed in the water to cause overpressure damage and wear on the surface of the piston.

In 2007, Industrial Co., Ltd. set up an offline supply system for laboratory instruments, MRO industrial products, etc. In 2009, it officially launched an online procurement operation platform. As the earliest enterprise engaged in MRO industrial products and laboratory instruments and meters in Shanghai, Shanghai Bayu Industrial Co., Ltd. has strong strength, scientific management, quality assurance, complete after-sales and reputation first.
10-inch tablet devices have greatly surpassed netbooks in terms of entertainment, including reading, games, and audio-visual enjoyment. In other respects, the basic operation of the 10-inch tablet computer built on the touch screen ensures that the application of the tablet computer can be well realized, and its operation performance is closer to that of a smartphone.
1.In appearance, the 10-inches tablet computer looks like a large-screen mobile phone, or more like a separate LCD screen.
2.In terms of hardware configuration, the 10-inches tablet computer has all the hardware devices of a traditional computer, and has its own unique operating system, compatible with a variety of applications, and has a complete set of computer functions.
3.The 10-inches tablet computer is a miniaturized computer. Compared with traditional desktop computers, tablet computers are mobile and flexible. Compared with Laptops, tablets are smaller and more portable
4.The 10-inches tablet is a digital notebook with digital ink function. In daily use, you can use the tablet computer like an ordinary notebook, take notes anytime and anywhere, and leave your own notes in electronic texts and documents.
