Q:What is the liquid pump? What are their categories? What are their strengths and weaknesses?
The pump is constructed by connecting large diameter gas piston with small diameter hydraulic piston. The two piston area ratio produces a pressure ratio, and the maximum output pressure can be calculated by the pressure ratio. High pressure ratio produces high outlet pressure. You can set the outlet pressure through a simple gas pressure reducing valve. Pressure ratio * gas drive pressure = output pressure.
Q:Suction stroke and lift of water pump
The absorption process is also called the "largest self-priming height" (also can be understood as "the degree of self suction). Micro pumps do not add water at the circumstances, can automatically water suction pump up the maximum height (the vertical distance from the pump to be pumped from the mouth of pumping liquid).Generally lower than the water pump positioned equal when there is self-priming pump required capacity. For example, outdoor tourism, need to extract the water in the river, with the best micro pump self-priming ability (impossible to people ran to the river water inlet pipe with water. It) or pumping the liquid corrosion, easy to add water and so on occasions.
Q:What are the main performance parameters of the pump?
RPM revolutions per minute. In N, the unit is R / minThe power delivered by the shaft power prime mover to the pump shaft. In P, the unit is kW.The ratio of useful power to shaft power of an efficient pump. With ETA said. It is an indicator of the degree of perfection of the pump in terms of hydraulic power
Q:What does "efficiency" mean in a water pump catalog?
General pump efficiency is 60% ~ 85%. high efficiency of the pump, indicating the same work, the pump consumes the lowest energy, and vice versa
Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same
Non negative pressure water supply equipment can be divided into non negative pressure tank and box type non negative pressure compensation device, steady flow tank type non negative pressure water supply equipment is the negative pressure tank, pressure tank can eliminate the negative effect of network equipment, is equipped with a vacuum suppressor and water protection box; non negative pressure water supply equipment has the advantages of simple device is a water tank with the boost voltage stabilizing device of complex box at the same time with no negative pressure tank.The tank type non negative pressure water supply equipment adopts vertical multistage centrifugal pump. This kind of pump is low noise and high efficiency. Such as CDL series and imported CR seriesOrdinary box type non negative pressure water supply equipment can use multi-stage centrifugal pump, also can use stainless steel submersible pump, submersible pump costs will be lower, but the maintenance costs will be high.
Q:How can I buy a pump?
2, must meet the characteristics of the media requirementsFor the delivery of flammable, explosive, toxic or valuable medium pump, requiring reliable sealing shaft or the use of non leakage pump, such as magnetic drive pumps (without shaft seal, using isolated magnetic indirect drive).For the transmission of corrosive medium pumps, convection components are required to use corrosion-resistant materials, such as fluorine plastic corrosion resistant pump.For conveying pumps containing solid particles, wear resistance materials shall be adopted in convection parts, and clean liquid shall be used for shaft seal when necessary.
Q:How accurate is the metering pump?
In addition, when the oil supply is too large or the pipeline pressure rises unexpectedly, the volume of the liquid in the hydraulic chamber can be changed, thereby affecting the stability of the flow and reducing the metering accuracy of the pump. In order to solve the problem of how to stabilize the measurement accuracy of metering pump metering pump flow, how stable, the three valve device. The so-called actual refers to the combination of three functions including compensation, discharge and safety protection device or device supporting the hydraulic chamber, according to its action principle is different, is divided into automatic compensation and forced compensation two three valve device.
Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?
2, the change of working volume is periodic, and in each cycle, the oil absorption process is changed from small to big, and the process of oil pressure is changed from large to small;3, suction oil cavity must be separated from each other without interference.
Q:The difference between submersible pumps and centrifugal pumpsWhat's the difference between the two? What is applicable and what?
Difference:The installation position is different: one can discharge water, one is on the ground.The work principle is different: the principle of submersible pump is similar to the electric fan, centrifugal pump through centrifugal force to make the water throw out. According to the principle of centrifugal force design,
Q:What flowmeter is installed after the pneumatic diaphragm pump?
According to your entire pipeline system to flow meter ah!How about the pressure, the material, the digital float or what?You must be sure of the size of the flow
