Q: How to adjust the flow of piston pump?: The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.

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: What is a water pump coupling device?: The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove

Q: How many millimeters is the diameter of the water outlet of the four inch pump?: If it is a centrifugal pump, the nominal diameter of the outlet is less than 4 inches, there is a conical short tube to enlarge the standard 4 inch outlet flange, from here, is the standard 4 inch flange connection.

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: 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: What is the function of the heating pump system for the water pump design?: Will cause some of the internal friction gap disappeared, the coupling center damage. In this case, starting the pump inevitably results in vibration, friction, etc.

Q: How many concrete pump tube diameter: The pump tubing diameter is 125MM general concrete or mortar pump tube diameter is 80MM fine stone

Q: Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?: Because the characteristic curves of the two are different.The power of centrifugal pump decreases with the decrease of flow rate. When the flow rate is zero, the power is minimum, so the centrifugal pump is started with a closed valve.

Q: What are the failures and causes of the replacement of the fuel pump assembly?: Common troubles of gasoline pump:Gasoline pump supply shortage of gasoline pump supply depends on the pump membrane stroke, stroke, pump oil should be more; however, the amount of gasoline pump oil pump will reduce the consumption of gasoline engine, and the fuel pump is inevitable, if the engine fuel consumption, but the actual amount of oil is less, this situation is the amount of oil in the petrol pump, there will be a float chamber of a carburetor oil level is reduced, the engine power shortage.
