Is there a moment when you see a dirty place being washed away by a high-pressure water gun and it becomes very clean, just like new, and your heart feels very comfortable. Today, I will share with you some comparison pictures before and after high-pressure cleaning. After reading them, you will definitely be shocked! …
Learn morePreparing for Camping fun or outdoor adventure. Or maybe you are thinking about spending a few days at the lake or in the mountains to go fishing. Some essential tasks will be needed and you would require electricity for that if you are out in nature. You will need to charge your phone in order to stay connected, turn on lights at night so you can see and make food hot enough that it is safe for y…
Learn moreWhat Is Plunger Pump? A plunger pump is a type of positive displacement pump in which the high-pressure seal is stationary and a smooth cylindrical plunger slides through the seal. This distinguishes them from piston pumps and allows them to be used at higher pressures. This type of pump is often used to pump municipal and industrial wastewater. Piston pumps, sometimes referred to as piston …
Learn moreThe efficiency of pumps refers to the ratio of effective power of pumps to shaft power of pumps. η=Pe/P The power of pumps normally refers to input power, i.e. the power conveying from prime mover to pump shaft, so it is also called shaft power and it is expressed as P. Effective power means product of pump lift, mass flow rate and gravity acceleration. Pe=ρg QH (W) or Pe=γQ…
Learn moreFor normal centrifugal pump, if the suction surface is below the impeller, it needs to fill water when starting the pump, which is very inconvenient. In order to store water in the pump, bottom valve is installed at the inlet of suction pipe, and when the pump works, bottom valve will lead to great hydraulic loss. But for the so-called self-sucking pump, it does not need to fill water when startin…
Learn moreThe cause of pump suction failure may be that there is air in the pump body or air accumulated in the inlet pipe, or the bottom valve is not closed properly or the water is not filled up with water, the packing of the vacuum pump seriously leaks, or the gate valve or flap valve is not closed properly. Eliminating method: pressurize water and, then fill up the pump body and then start the pump. Mea…
Learn morePower optimal selection will enable you to make the best use of you generator, and this document will help you to: • Use a small and cheap generator that can also meet your requirement. • Use the generator more efficiently. Power optimal selection is based on a simple concept that simultaneously using all the electric households is not necessary. When using one electric device…
Learn moreAVR circuit is composed of rectifier main circuit, voltage detection circuit and comparison and control circuit; excluding the possibility that the damage is caused by the quality problems of the electric components, the working frequency of the main circuit and comparison and control circuit changes most among the whole AVR circuit. And the rectifier bridge in the main circuit and the transistor …
Learn morea. The air filter is too dirty and the suction air is insufficient. The air filter must be cleaned or replaced now. b. The fuel strainer is too dirty, and fuel injection quantity is not enough. It needs to be replaced or cleaned. c. Fire ignition time is not right and needs to be adjusted.
Learn moreBefore choosing a generator, you need to know Maximum power and rated power The power of a generated indicated in advertising is generally the maximum power that the manufacturer can produce. However, you can also see the indicated rated power. Maximum power= the maximum power output that the generator can produce, which normally can only lasts for 30 minutes. Rated power= the …
Learn moreDead center: piston is connected with crank and rod assembly. The piston has top and bottom limit positions in the cylinder. The top limit position is called top dead center, which is the farthest from the crankshaft centerline. The bottom limit position is called bottom dead center, which is the nearest to the crankshaft centerline. Piston stroke: The distance of piston movement from top …
Learn moreIn the event of faults of the carburetor such as starting difficulty, unstable idle speed, power shortage and oil leakage, clean and adjust the carburetor promptly. Dismantle the carburetor, firstly clean the external parts of the carburetor, and then dismantle and clean each main part (it can be cleaned by special detergent for carburetor). The main cleaning parts are main oil passage orifice,…
