Product Description:


1. Product Introduction:

ZX series self-priming centrifugal pump falls into the category of self-priming centrifugal pump,which has such advantages as compact structure, easy operation, stable running, easy maintenance, high efficiency, long life and strong self-priming capacity. The bottom valve needn't be mounte in the pipeline. It 's only necessary to reserve a fixed quantity of guide liquid in the pump body before work. Therefore, it simplifies the pipeline system and also improves the labor conditions

2. Range of Application:

1) It is applicable for city environmental protection, building, fire control,chemical engeering,pharmacy,dyestuff,printing and dyeing, brewage, electricity, electroplating, paper making ,petroleum, mine, equipment cooling, tanker discharging,etc.

2) It is applicable for clear water, seawater, liquid containing acid or alkali chemical medium, and generally pasty slurry (medium viscosity≤100cP and solid content less than 30%).

3) When it's mouted with an arm sprayer, it can jet the water into the air to disperse into little raindrops for spraying , so it is a good tool for farm, nursery, orchar and tea garden.

4) It can work with any types and specifications of filter press, so it is an ideal type to deliver the slurry to the filter for the filter pressing.

Q:Which nuclear submarines use the shaftless pump technology?
Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.
Q:What is the difference between centrifugal pump and rotary vane pump?
This is a classification problem.Rotary is classified by movement, vane pumps are rotary, volumetric pumps are mostly rotary, piston pumps, etc., is reciprocating.
Q:Advantages and disadvantages of centrifugal pumps?
Centrifugal pump; advantages and disadvantages:(1) advantages:The structure of the pump is simple and compact, and the centrifugal pump has small area, light weight, little material consumption and high cost for the foundation. Therefore, the cost of manufacturing and installation is less.For high speed operation, the 2 pole or 4 pole motor can be directly connected. The drive structure is simple and easy to install.
Q:Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q:What are the general water pump failure, how to repair?
(2) in contact with the water pump inlet of the horizontal application of reverse flow direction, fell more than 0.5% slope, connect one end of the highest import pumps, do not completely level. If the upward tilt, the intake pipe will retain air, reducing the water pipes and pumps in the vacuum, water absorption.
Q:What is the pump lift voltage? And how to suppress the pumping voltage rise?
[pump voltage] when braking, in the motor winding series resistance, motor equivalent to the generator, the energy will be converted to electric energy consumption in the series resistance. This method is widely used in all kinds of motor braking, and frequency conversion control is also used. From high to low (zero speed), then the electrical frequency changes quickly, but the rotor of the motor with the load (production machinery) mechanical inertia, could not stop quickly, resulting in the back EMF (EU voltage) motor is in the state of power,
Q:Fire pump and shower pump flow head selection, high resolution.
2, the volume is greater than 10000 is less than 25000, the minimum water consumption of indoor fire hydrant is 15L/s
Q:What should be used to pay attention to the use of mechanical pumps?
When opening the pump, first close the outlet valve, lift the pressure, then open the outlet valve again, pay attention to the flow of the motor.
Q:What is the lift of diaphragm pump?
Tell you: diaphragm pump head is liquid through the pump energy obtained is called lift it, and flow and pump speed, a liquid density is generally 1 kg is 10 meters lift, horizontal pipeline 10 meters 1 meters lift, a 90 degree bend is 1 meters.
Q:What is the displacement of the pump? Flow? What is the volume efficiency and mechanical efficiency of the pump?
Displacement of a pump: the volume of the discharged liquid calculated by the change in the size of the sealing geometry for each revolution of the hydraulic pump
