development of pump energy saving products.Self-priming centrifugal pump, the pump and other pump does not have the self-priming capacity, etc.Such as corrosion resistant mechanical seals and stainless steel material can call some of the chemical, pharmaceutical acid and alkali medium.
Second, the product features
1, the pump with self-priming function, do not need to install the bottom valve in pipeline, only to ensure storage in pump body before work are quantitative liquid can have "a drainage, life-long self-priming" function.So both simplifies the pipeline system, and improved the working conditions.
2, has a compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life.
Three, use the product
1) suitable for urban environmental protection, construction, fire control, chemical, pharmaceutical, dyes, and dyeing, brewing, electric power, electroplating, papermaking, oil, mining, equipment cooling, tanker unloading, etc.
(2) apply Yu Qingshui, sea water, chemical liquid medium with acid, alkalinity and with general mushy slurry (medium viscosity 100 mile, or less under the solid content of 30%).
(3) mount a rocker arm sprayer, the water can go into the air, a small drips to spray, is a good tool for farm, nursery, garden, tea garden.
And (4) can be matched with pressure filter of any model and specifications, sending size belt filter to filter the most ideal auxiliary pump.
Fourth, working conditions
Traffic: 3 ~ 500 m3 / h
Head: 10 ~ 80 m
Ambient temperature 50 ℃ or less
Medium temperature is 100 ℃ or less
Medium density of 1.24 or less by 103 kg/m3
- Q: Know flow and lift how to calculate the pump power?
- The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.
- Q: What is the dry running protector of screw pump? What's the principle and function? Thank you
- The utility model relates to a screw pump dry running protector, which is used for protecting the stator and the rotor of the screw pump from being transported by air
- Q: If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?
- If the fish tank is made of metal, the fish tank is grounded or connected to the zero line, and then the fire line is put into the water, then your fish will be electrocuted immediately. Go back to the submersible pump, submersible pump line and the zero line very close, even if the firing line and the zero line at the same time the leakage occurs, fish could not swim between the firing line and the zero line, so the tank submersible pump leakage will cause the following hazards: 1, electric shock. 2, submersible pump short circuit. 3, the submersible pump serious fever, resulting in water temperature tank.
- Q: Water pump can not be pumped out, how to maintain water?
- Packing overheating:Due to packing too tight, the cooling water can not enter the filler, or the shaft surface damage. Measures for proper relaxation of packing and cleaning of sealing pipe are adopted. Filler wear must be replaced with new ones. Before installation, soak in the oil and rotate it in turn. The incision should be staggered so that water leakage can be reduced. Fill the last lap after installed loading pressed to cover operation for further adjustment of the tightness.
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- However, the centrifugal pump will have its import pressure requirements, which is to prevent cavitation, that is, the fear of the delivery of liquid at low pressure will occur gasification. Centrifugal pump has an important parameter called NPSH, for example relating to the inlet pressure, the pump NPSH, 4 meters, it means that the absolute pressure of imports should be higher than the saturated steam conveying fluid pressure of liquid column is 4 meters high, so, when it is at a temperature of saturated vapor pressure for water transport 2 meters, 4+2=6 meters minimum inlet absolute pressure. Because the absolute pressure is 10 meters water column atmospheric pressure, at this time the entrance negative pressure is 10-6 meters =4 meters water column.
- Q: What does centrifugal pump mean horizontally?
- Centrifugal pump: centrifugal pump is a centrifugal force on the impeller rotates to transport liquid pump. Centrifugal pumps use the impeller to rotate and cause centrifugal motion of the water to work. The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
- Q: Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?
- Four) release bolus dosage method can use automatic release and manual release two ways, the key is to alarm after the infusion must be stopped(five) any kind of pill dose release are not restricted to replace the pill. The total dose limit for in pipe blockage after pill agglomeration process will remove blocking accident, this time will be the rapid infusion of pill dose concentration into the patient's blood, if the total dose pill does not get test and limit, rapid infusion of this accident it may have unimaginable consequences.(six) supplies open type infusion pump overflow on the domestic market for pill characteristic parameters of consumables simply without testing and limitation. Therefore, the risk of accidental pill has become one of the residual risk of open type infusion pump supplies the most deadly.
- Q: Why is the flow of the pump too small will occur cavitation phenomenon?
- This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
- Q: Centrifugal pump flow, why can be adjusted through the outlet valve? Can the flow of the reciprocating pump be adjusted in the same way?. Why
- Reciprocating pump is a positive displacement pump, the volume change of flow is the unit of time, constant flow speed constant, can not rely on increased resistance to change the flow resistance increase is only leaked, only small changes in flow.
- 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.
