Product introduction:
QDX. QX series submersible pump consists of pump, mechanical seal and motor. Pump is at the bottom part of pump, which is adopted centrifugal impeller.Motor which is monophase or three phase is at the upper pa" of pump and seal is used where pump and motor combine, which is a kind of double end mechanical seal "O " rings are applied to all static joints. Floator switch can be equipped to control pump" starting and stopping automatically according to the water level.

Application:
This series pump is small and light, which is widely used in countryside for elevating water from well, irrigation, sprinkling and domestic water supply, and also used in draining off water for fishpond and building site.

Work Conditions:
The pump can work properly and continuouslyunder following operational conditions:
1 .Medium is not corrosive, Sand contents shouldbe max. 0.10% by volume and granular sizeshould be max.0.2mm.
2.Medium temperature shouldn’t be over 40℃ and PH should be6.5-8.5.
3.The pumps should be operated within rated head.
4.The pumps should be fully submerged into water with depth of less than 3m mad max. the pump should be min.0.5m over the water bottom and not be inserted into sludge.
5.Power frequency should be 50Hz, single phase voltage 220V, three-phase voltage 380V, and voltage fluctuation should be 0.9-1.1 times than the rated .

Q: Is the vacuum pump air compressor?: A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.

Q: What does electromechanical vector pump mean?: It is a close set of mechanical and microelectronic technology. It adopts dual control center mode to control, and has a new water pump with logic control center and IPC control center.

Q: What are the application areas of pumps?: Performance range from the pump to see giant pump flow up to hundreds of thousands of cubic meters per hour, while the micro pump flow per hour in a few milliliters; pump from atmospheric pressure up to 19.61Mpa (200kgf/cm2); the lowest temperature of the liquid is transported up to -200 DEG C, up to 800 DEG C. Pumps carry a wide variety of fluids, such as water (clean water, sewage, etc.), oils, acid and alkaline solutions, suspensions, and liquid metals.In the chemical and oil sector production, raw materials, semi-finished products and finished products are mostly liquid, and semi-finished and finished products to raw materials, need to go through a complex process, to pump and provide transportation of liquid chemical reaction of the pressure and flow in the process, in addition, the device also used in many pumps to adjust the temperature.In agricultural production, the pump is the main irrigation and drainage machinery. Rural areas in our country are vast and vast, and a large number of pumps are needed every year in rural areas. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most widely used equipment in the mining and metallurgical industries. The mine needs pumping and drainage. In the process of ore dressing, smelting and rolling, the pump needs water to supply water first.

Q: Difference between pump and compressor: In the spiral case, the liquid slows down due to the gradual enlargement of the flow passage, and the part of kinetic energy is converted to static pressure, and finally flows into the exhaust pipe at higher pressure and is sent to the required place. When the liquid flows from the center of the impeller to the outer edge, a vacuum is formed at the center of the impeller. As the pressure at the upper level of the tank is greater than the pressure at the pump inlet, the liquid is continuously pressed into the impeller. Visible, as long as the impeller continues to rotate, the liquid will continue to be inhaled and discharged.The working principle of the linear pump is different from that of any other pump. It adopts the principle of magnetic suspension and the hydraulic structure of the spiral ring to realize liquid propulsion, that is, to cancel the shaft, to cancel the shaft connection, and to cancel the sealing structure of the shaft. After starting, the electric current is transformed into a magnetic field, and the magnetic field force drives the spiral ring to move, namely, the spiral ring promotes the liquid advance.Compressor (compressor), a driven fluid machine that promotes low-pressure gas as a high pressure gas, is the heart of a refrigeration system. It is of low temperature and low pressure refrigerant gas suction pipe from the suction, through the operation of the motor drives the piston to compress it after high temperature and high pressure refrigerant gas discharge pipe to the exhaust, to provide power for the refrigeration cycle, so as to realize the compression and condensation (exothermic), expansion and evaporation (endothermic) refrigeration cycle.

Q: Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role: The spoon pipe is not a feed pump, but also is an adjusting oil inlet device of a hydraulic coupler matched with a feed pump

Q: Harm of air pump and pump: If the liquid is not full, this situation is generally the suction pipe or pump shell leakage, then easy to cause cavitationHit the pump for centrifugal pumps, centrifugal pump is recommended to start closed, the discharge valve closed, starting is in the state of pump

Q: The working principle of magnetic pump: Working principle of magnetic pumpN of the magnet (n is even) arranged according to the laws in the magnetic clutch assembly inside and outside the magnetic rotor, the magnet part consisting of magnetic coupling system. When the inside and outside the two poles in different relative displacements, two poles between the angle phi = 0, the lowest energy magnetic system; when rotates to the relative displacement is two poles, pole angle between phi = 2 pi /n, the magnetic system of magnetic energy. Remove the external force, due to the magnetic system of magnetic poles repel each other, magnetic magnet will return to the lowest energy state. So magnets in motion, driven by the magnetic rotor.

Q: Because the water pressure of the booster pump is not enough, it can not work automatically. It can only be operated by hand. It is inconvenient to use.: One possibility is the automatic type household booster pump used for a period of time, automatic failure phenomenon, it is mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging. Can be re used. But that's not why if your booster pump isn't working properly all the time.

Q: What flowmeter is installed after the pneumatic diaphragm pump?: The pressure decreases, the diaphragm moves slowly, and the flow decreases.This is not particularly accurate, because the diaphragm is not a metering pump, but the approximate flow can still be controlled.

Q: What is the series of pumps? What is the difference between a unipolar and a multilevel? What is the meaning of each "first class"?: Each impeller is of the first stage. (two impellers share only one level, and exit is only level one)
