At the same time, we will provide necessary follow-up service assurance. Normally, We have 1 year warranty.

③How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. It related to the state and detailed requirement of customers.

Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: (1) the disk, stator or bushing is worn and shall be inspected, trimmed or replaced with a rotary vane vacuum pump.(2) the pump temperature is too high, which not only reduces the viscosity of the oil, increases the saturated vapor pressure, but also may cause cracking of the pump oil. Ventilation, cooling and environmental temperature should be improved. If the exhaust gas temperature is too high, should be cooled before entering the pump, the environment temperature is high, should try to use a better high speed vacuum pump oil or 3# diffusion pump oil. (10) because of the deformation, wear or movement of the parts, the maximum opening height of the check head can be reduced or even unable to be opened, the intake of oil is too little, and the vacuum degree of the rotary vane vacuum pump is reduced, and should be adjusted as shown in the assembly section. Open high, more oil, but open too high, check valve in some places on the stop, it will not automatically drop, lost to prevent oil returns. The commonly used rotary vane vacuum pumps mainly include double stage rotary vane vacuum pump and single-stage rotary vane vacuum pump

Q: The function of centrifugal pump: 6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.

Q: What is the name of the day pump and ground pump? Specific introduction: People often say "day pump" actually refers to the boom pump, it also has many other name, such as pump, boom pump, concrete pump, concrete pump truck, these words are "day pump".Ground pump, in fact, refers to the pump drag pump. Therefore, to understand the difference between day pump and ground pump is to understand the difference between the boom pump and the tow pump

Q: How to select metering pump head?: In metering fluoride, we recommend the use of Viton, sealed PVC pump head. For most chlorination applications, it is better to use EPDM sealed NP (plexiglass) pump head. For hydrogen peroxide mixtures, only PTFE sealed PTFE pump head or stainless steel pump head can be used

Q: What is the "variable" of a variable pump? Is the displacement change or the flow change? Thank you: There are many ways to change the variable pump flow: by changing the eccentricity to change the piston stroke length (radial piston pump, the frequency change principle) motor speed to adjust the flow (such as gear pump flow control principle).

Q: Brief description of centrifugal pump on / off operation: Two, centrifugal pump start(1) the pump entrance valve fully open, start motor, outlet valve fully closed, fully check operation of pump.(2) when the pump outlet pressure is higher than the operation pressure, the outlet valve is gradually opened to control the flow and pressure of the pump.(3) check whether the motor current is within the rated value, such as the pump in the rated flow operation, and the motor overload should stop the pump inspection.

Q: The main factors affecting the performance of centrifugal pumps: The low specific speed pump, on the other hand, is suitable for smaller flow and higher lift. When the pump outlet pipe diameter at the same time, if the two pumps flow similar, smaller than the speed of small head, shaft power consumption is also large. Generally speaking, the centrifugal pump with smaller revolutions than the impeller has a narrow outlet width and a large outer diameter, and the channel formed by the blade is narrow and long. If the ratio of revolutions is large, the impeller outlet is wide and the outer diameter is small, then the flow passage is short and wide.I hope my answer will be helpful to you. I hope to adopt it!

Q: What are the main performance parameters of hydraulic pumps?: speedOperating speed is the actual rotation speed of a pump (or motor) at work.Rated speed is the maximum speed that can operate normally for a long time under rated pressure. If the pump exceeds the rated speed, the work will cause insufficient oil absorption, vibration and noise, the parts will suffer cavitation damage, life expectancy.Minimum steady speed is the minimum speed allowed for normal motor operation. At this speed, the motor does not appear crawling phenomenon.

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: Does the control cabinet of the fire control pump need to be related to the fire control room?: Normal words are needed, but when you check and check, has anyone checked?
