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:What's the word "pump"? Is that what advocates mean?RT
What is a "fan"?In recent years, the term "fan" often appears on the newspaper Web page, whether it is a team, a singer, a sports car and a toilet, all of which have their own fans
Q:What is the "variable" of a variable pump?
Variable pump variable refers to the flow can be changed to distinguish from the constant flow of quantitative pumps.
Q:The water tank of the fish tank does not air out and only has the water outlet
The air inlet pipe is connected with the oxygen burst, the entrance also pulled out, we can see that it is the design of a miter, the oblique incision back to the direction of the water flow speed, this outflow, negative pressure is formed in the oblique incision, the air can be sucked in. As shown.
Q:What are the functions of a disposable infusion pump?
With the development of science and technology, more and more fields need to control the flow or velocity of fluid accurately. For example, the detection and analysis of micro chemical elements in chemical industry always need to control the flow accurately. In the field of health care, the flow and velocity of traditional Chinese medicine liquid must be controlled accurately.Venous transfusion is one of the most commonly used methods of clinical treatment. It is a common medication and treatment technique for nursing specialty. Clinically, appropriate infusion rate should be applied according to the drug and patient's condition. Transfusion too fast may cause poisoning, more serious can lead to edema and heart failure;
Q:Must the water pump in the tank be all soaked in water?
Usually you have to soak it all in the water. If you don't want to put it in the water, you can buy an amphibious pump. At most, you can expose it
Q:What are the constant pressure pumps?
Constant pressure pump is also called the booster pump, the name is used for booster pump, its main purpose is water heater booster, with tall low pressure, sauna, bath and other pressure in the apartment, the lack of water pressure, solar automatic pressurization and so on.
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:How should the water pump be installed?
(4) before installation, make sure all pipes connected with the pump should be clean, and no solid foreign bodies which may cause damage to the pump shall be allowed.(5) apply the blind flange or other things to the suction, exhaust or open pump to ensure that no sundries enter the pump cavity during the installation.(6) check whether the pump random data is complete and complete; whether the pump surface has obvious damage. Only with complete data, no obvious damage to the pump, you can continue to install.(7) the installation of centrifugal pump with the coupling of the hand when turning slowly rotating coupling or pulley, observe the pump rotation are stable, flexible and adjustable, the rotor parts have no jamming, the pump has no debris crash, bearing the operation is normal, with elastic suitability.
Q:What is the difference between centrifugal pump and positive displacement pump?
Positive displacement pump is the volume pump, this type of pump is to rely on changes in volume to compress fluid work, including: diaphragm pumps, gear pumps, screw pumps, etc.;
