r-br: br-,: -r:B/. Pneumatic diaphragm pump Bei Weiwei came out of the bathroom and walked to his computer. I saw such a scene, the heroine in red was surrounded by crowds of people, but they had a tacit understanding to create a circle around the heroine, leaving the heroine alone and standing in the middle with a forlorn back. Then the words kept popping up on the heads of those around them, and the most frequent one was "Support Lu Weiwei's marriage grabbing!" Support Luwei Weiwei’s marriage grab! B/. Pneumatic diaphragm pump supports Luwei Weiwei! Support Luwei Weiwei’s marriage grab! Support Luwei Weiwei’s marriage grab! Support Luwei Weiwei’s marriage grab! Support Luwei Weiwei’s marriage grab! Support Luwei Weiwei’s marriage grab! Wei Wei is stunned. B/.Pneumatic diaphragm pump

r-br: br-,: -r: Pneumatic diaphragm pumps are mainly used for Mine roadway development, shaft shaft construction, sewage discharge around mining working face tanks and various equipment, drainage, sewage sand discharge, mud discharge in underground cave chamber projects, mine roadway spray whitening applications, etc. The pneumatic diaphragm pump produced by our company adopts, absorbs and improves the most advanced pneumatic diaphragm pump production process and technology in the world. This product is specially designed for coal mines and has traditional submersible electric pumps, mud pumps, impurity pumps and flexible shaft pumps. All functions are a revolution in traditional mining water pumps. The key is to completely solve the safety issues of traditional water pumps. The product can provide high conveying speeds at low air pressures and is compatible with a wide range of materials. This water pump has an anti-stall design and a modular pneumatic motor/fluid part.
r-br: br-,: -r: Pneumatic diaphragm pumps are used to discharge clean water underground in coal mines or sewage containing solid particle impurities (volume concentration less than %). They can also be used in non-coal mines to transport media. Similar other occasions. B/. Pneumatic diaphragm pump multi-industry submersible pump, Dongda Electromechanical Manufacturing

r-br: br-,: -r: Diaphragm pump troubleshooting guide When encountering one or more of the following situations, this information can be used as Guidance to help you formulate maintenance measures.
r-br: br-,: -r: As shown below, there are several abnormal operating conditions described in this guide: ) Fast cycle/low flow B) No cycle/slow cycle/irregular cycle) Leakage) Noise) Component breakage
r-br: br-,: -r: During the application of the pump, these situations are likely to be encountered. Each situation can be divided into several possible causes. This guide lists the causes of malfunctions and provides corresponding correct repair measures. The meanings of all specific terms in the guide are listed below. Water hammer effect -
r-br: br-,: -r: Water hammer is when there is a sudden power outage or when the valve is closed too fast, due to the inertia of the pressure water flow, a water flow shock wave is generated, just like a hammer hitting, so It's called water hammer. The force generated by the back and forth shock waves of water flow can sometimes be so great that it can damage valves and water pumps. The water hammer effect means that inside the water pipe, the inner wall of the pipe is smooth and the water flows freely. When the open valve is suddenly closed, the water flow will generate a pressure on the valve and pipe wall, mainly the valve. Because the pipe wall is smooth, the subsequent water flow quickly reaches the maximum under the action of inertia and produces destructive effects. This is the "water hammer effect" in hydraulics, that is, positive water hammer. This factor must be considered in the construction of water conservancy pipelines. On the contrary, when a closed valve is suddenly opened, it will also produce water hammer, which is called negative water hammer. It also has a certain destructive power, but it is not as big as the former. .

r-br: br-,: -r: Air valve--The copper or stainless steel valve housing is fixed on the center body of the pump by four bolts.
r-br: br-,: -r: Piston--an aluminum cylinder enclosed in the air valve that controls the air flow.
r-br: br-,: -r: Cavitation--Due to the reduction or lack of fluid supply at the pump inlet, the pump discharge volume is lower than the rated volume. In fact, the liquid chamber is filled with fluid before discharge.
r-br: br-,: -r: Jingpai pressure relief head--the vertical distance (in feet) from the center line of the pump to the free delivery point. Inlet pressure--the inlet is measured in pounds. , including the specific gravity and flow rate of the fluid.
r-br: br-,: -r: Specific gravity--the ratio of flow rate to water weight. The specific gravity of water is.
r-br: br-,: -r: Static suction head - the vertical distance from the supply liquid level to the center line of the pump. The pump should be above the liquid level.
r-br: br-,: -r: Vapor pressure--the pressure produced by the vapor of all liquids on their free surface. In any pump operating system, the operating pressure cannot be lower than the vapor pressure, otherwise the vapor formed will partially or completely cut off the flow to the pump. Viscosity - the property of viscosity that causes flow resistance in a fluid due to the presence of internal friction in the fluid.
