Structural Characteristics
Pump is vertical structure,motor cover and pump cover are connected to be designed.Beautiful appearance,little occupied area.It can be used outdoor if a protective cover is installed.
Inlet and outlet diameter of pump are the same and they are on the same center line,which can be installed on the pipeline directly just like valves,and the installation is very convenient.
Excellent foot design makes the installation and steadiness of pump convenient.
Pump shaft is lengthened shaft,and this solves the vibration problem caused by coupling drive that is applied by common centrifugal pump shaft and motor shaft.Chromeplate treatment shall be proceeded on surface of pump shaft,which greatly prolongs the service life of pump.
Impeller is directly installed on the motor lengthened shaft.There i no noise when pump is operating,motor shaft applies low noise bearing,which greatly improved the operating environment.What’s more,non-malfunction working time of pump has prolonged 3 times than the common pump.
Mechanical seal is used on the shaft seal,which solves the severe leakage problem caused by packing seal of common centrifugal pump.Static ring and rotating ring of sealing are made of silicon carbide,which prolongs service life of seal.
There is a exhaust hole on the pump cover.Outlet hole and pressure hole are on the flanges downside and two sides of pump casing in order to make pump operate,maintain normally.
Unique structure,so there is no need to dismantle pipe system.Just dismantle pump cover nut,then begin to maintain.It is very convenient.
Series connection,parallel connection and enlarging of pipe diameter can be applied according to requirements,namely,capacity and head.
Max working pressure of pump system≤1.6MPa,namely “pump suction pressure+pump head ≤1.6MPa”.When ordering,system working pressure shall be marked.If pump system working pressure is more than 1.6MPa,it must be specified when ordering so that cast steel material can be applied when manufacturing.
Environmental temperature＜40℃,relative humidity＜95%.
Volume content of solid particles in the transported medium shall no exceed 0.1% of unit volume,granularity＜0.2mm.
Remarks:If medium contains tiny particles,please specify when ordering,so that the wear-resistant mechanical seal can be applied.
- Q: How can the submersible pump level meter be connected?
- Installation of submersible pumps dedicated liquid level float, connected to the submersible pump power line (some submersible pumps bought with), or received submersible pump control circuit, high starting, low stop.
- Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?
- (1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.
- 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 causes of pump shock?
- Troubleshooting cause1. bearing damage, replace new bearings2., coupling pin, bolt damage, rubber column or metal bolt wear, change
- Q: What's the meaning of the pump head in the water pump, please advise, thank you
- The pump head of the centrifugal pump refers to the shell that contains the impeller and impeller, and also includes the shaft part that drives the impeller. It can be used as the part of the motor and shaft coupling and the base.
- Q: Please give me professionals to calculate, the cylinder bore is 100 and the rate of 20m/s, the leakage can be ignored, but to the large flow pump!
- 3. efficiencyVolume efficiency, for hydraulic pumps, is the ratio of actual flow to theoretical flow. A hydraulic motor is the ratio of its theoretical flow to its actual flow.Mechanical efficiency, for hydraulic pumps, refers to the ratio of theoretical torque to actual input torque. The actual output torque of the hydraulic motor is theoretical torque to overcome the torque after friction, so the mechanical efficiency is the ratio of the actual output torque to the theoretical torque.
- 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?
- (1) the pellet dose in the safety standard of the infusion pump refers to the amount of liquid that is transported to the patient in a short period of time(two) pill dose limit is mainly to control the risk of accidental pill dosage. Especially after the mandatory requirements of pipe blockage in the elastic pipe storage liquid limit amount of agglomeration and the limitation of these methods to release pill dose.
- Q: Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?
- Start the pump. Water pressure depends on how large you buy the pump, generally small, mostly 10-15 meters hydraulic pressure, about 200 of the price.
- Q: How many square cables does the submersible pump for 7.5KW need?
- I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).
- Q: Filter backwash pump for what use, what is the principle of work ah?
- When the filter is in normal operation, the impurity will be trapped in the upstream of the filter (filter medium). As the accumulation of impurities, the filter media will be blocked, and the direct performance is that the circulation will decrease. Usually, when the flow drops to a set point (the industry is usually judged by the pressure drop),
