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:Which nuclear submarines use the shaftless pump technology?
At present, the submarine has been used in the pump jet technology, the most representative is the United States Virginia class submarine and the Russian North Sea God class submarines.. And shaftless pump is a derivative application of superconducting technology, which is more advanced than pump jet technology..If you want to learn more about shaftless pump technology, you can find relevant papers online.
Q:What does electromechanical vector pump mean?
Scope of application is;Residents living water: such as high-rise buildings, residential areas, villas and so onPublic places such as hospitals, schools, gymnasiums, golf courses, airports, etc
Q:Why does the centrifugal pump close the pressure to start?
Therefore, the operation rules of multistage centrifugal pumps require that the inlet valve be opened before opening, and the outlet valve is closed. However, the export valve closed time can not be too long, because at this time the medium in the pump cycle, the medium temperature gradually increased, easy to cause mechanical seals, due to lack of lubrication friction and wear or damage.
Q:Metering pumps related matters
2) change the metering pump diaphragmTrouble is often encountered when the old diaphragm is removed. Provide some additional advice on how to remove the old diaphragm.After in the pump head loose, remove the pump head before the stroke length adjustment to the 10% position. To ensure that the electromagnetic axis has sufficient pressure to maintain its connection firmly, so that you can unscrew the diaphragm.The pull end torque from the Jack out of the screw. Seize the liquid counter clockwise rotation. There is a slight resistance that can unscrew the diaphragm.Chemical 3 measurement may end in fluid crystallization, resulting in a one-way valve ball and seat valve does not work.In the end inhalation metering pump may have a gas leak. Hydraulic end suction side connector may lack O ring or suction valve connection loose.3) flow monitoring and measurement of a high viscosity medium, in the process of liquid delivery received a flow failure signal, how can we solve this problem?Move the hydraulic end by loosening the 4 pump head screws. Rotating stroke length to 10%, and seize the hydraulic end, and then slide out of the screw hole, then the screws do not touch them, but still control the back and diaphragm. Then rotate the component counter clockwise, with a slight resistance, and the diaphragm will loosen from the electromagnetic axis. If the diaphragm is not loose, use some grease on the contact surfaces of the diaphragm and the electromagnetic shaft. After a few minutes, gently tap the diaphragm with a small plastic hammer. Then proceed again in accordance with the above description.
Q:What are the conditions required for hydraulic pumps to complete oil absorption and compression?
There must be one or more sealing volumes, and the volume of work is variable;
Q:What are the characteristics of a vertical multistage centrifugal pump?
Vertical multi-stage centrifugal pump is cast iron, the advantage is that the price is cheap, the disadvantage is bulky and power consumption.
Q:Fire hydrant pump button, under what circumstances do not need to install?
The installation of hydrant pump buttons depends on the type of water supply:(1) municipal water supply; (in this case, do not have to install)(2) there is a fire pump; (must be installed)
Q:Operating procedures for measuring pumps
3, discharge pipeline unimpeded.4, the pipeline should meet the positive pressure head, that is, in high flow suction conditions work.5, check the direction of the pump, strictly prohibited reverse.6. Check the oil level in the crankcase compartment. For multi cylinder pumps, check that the oil level has reached the required level.7 、 pump motor static grounding is good, meet the requirements.
Q:How to select metering pump head?
The manufacturers of chemicals will give relevant recommendations, or consult the ProMinent chemical corrosion chart to determine the compatibility of the chemicals with the contact material.
