Production Introduction:
JET series pumps have the advtanges and characteristic of self-priming pumps and centrifugal pumps. Water jet elements realize self-priming function.Pumps by the optimized design, have the advantages of bigger suction, high head, smooth operation, and reliable performance, which is the ideal tool for agriculture, and household, etc

Application:
This series pump is a new type of ideal economical household pump, and widely used in pumping water from well, increasing water pressure, garden irrigation, water supply for vegetable green houses, industrial mining enterprises and aquatic breeding fields etc.

Work Conditions:
The pump can work properly and continuously under following op¬erational conditions:
1.Medium is not corrosive. Sand contents should be max.0.10% by volume and granular size should be max.0.20mm.
2.Medium temperature shouldn’t be over 40℃and PH should be6.5-8.5.
3.Power frequency should be 50Hz,single phase voltage 220V, and voltage fluctuation should be 0.9-1.1 times than the rated.

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: What are the internal losses in centrifugal pumps? How did they come about?: Volume loss: loss due to leakage;3. mechanical loss

Q: What are the characteristics of a pipe shield pump?: According to the transmission of liquid temperature, pressure, viscosity and particle level have different requirements, the pump can be divided into the following types: first, the basic type (standard type) transport medium temperature does not exceed 120 degrees, the head of not more than 100m, the pump other types are variations on the basic type and improved.

Q: Water pump outlet valve sequence: Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.

Q: How many kinds of pumps are available and the operating principles of various pumps?: There are many kinds. See what divides.According to the working principle can be divided into: the power type pump, also called pump or impeller vane pump, depending on the dynamic effect of the rotation of the impeller on the liquid, the continuous energy transfer to the liquid, the liquid kinetic energy (mainly) and the pressure will increase, then converting kinetic energy into pressure energy through the discharge chamber, and can be divided into centrifugal pump, axial flow pump, partial flow pump and vortex pump etc..

Q: Does the reservoir water heater press the booster pump (high marks)?: The outlet water pressure of hot water is the same as that of cold water. The water heater is pushed by cold water to push out the hot water. (of heating). Installation location about 2 meters away from the ground, the impact of water pressure is not large, in rural areas, the installation position in more than two buildings will have an impact. In the city, the installation position is above four floor to affect the water pressure.

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: What is an industrial water pump?: The pump has the different uses, conveying different liquid medium, different flow rate, different lift range, therefore, its structure of course is not the same, the material is different, in general, can be divided into:1, urban water supply 2, sewage system 3, civil and construction systems 4, agricultural water conservancy system 5, power station system6. Chemical system 7, petroleum industry system 8, mine metallurgy system 9, light industry system 10, ship system

Q: Why can't the centrifugal pump pump the vacuum?: Running process: depending on the centrifugal pressure of the liquid in the impeller, the liquid is sucked into the liquid, and the liquid in the pump shell has the conversion of the energy form, so that the fluid can obtain the mechanical energy mainly with the static pressure.The characteristics of the system: the suction diameter than out of large diameter, the general valve installed.

Q: How to maintain and repair the booster pump of pipeline pump?: I. installationAssembly and disassembly1. scrub all the spare parts to be cleaned.2. mechanical seals are installed on the main shaft of the motor, and a small amount of clean turbine oil or 20 oil is added to the surface of the mechanical seal.
