Production Introduction:
QJD. QJ Multistage Deep-well submersible pump consists of motor and multistage pump.The pump consists of impeller,vane,pump body, inlet flap,outlet flap,shaft and bearing.The motor is applied with double -face mechanic sealing with"0" shaped rubber ring as static sealing.
Application:
This series pump is extensively used for electrical irrigation, forest water spraying, water pumping from well, water tower deliver and urban construction water supply and discharge for farms, villages, industrial and mining enterprise.
Condition of usage:
The pump can work properly and continuously under following operational conditions:
1.Medium is not corrosive .Sand contents should be max.0.10% by volume and granular size should be max.0.20mm.
2.Medium temperature shouldn’t be over 40*C and PH should be 6.5-8.5.
3.The pump should be opera ted within rated head. The pump should be min.0.5m over the water bottom and not be inserted into sludge.
4.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: 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: 5 floor water pressure is too low, what kind of water pump is better?
- The location of the pump is too far away from the pumping pool, the suction of the pump is not enough, cavitation phenomenon, pumping water, this water pump manufacturers, the pump will be placed in a reasonable position
- Q: Variable flow pumps are variable pumps
- To be exact, variable pump means variable displacement. Because if the displacement does not change
- Q: What are the ways of hydraulic pumps?
- There are several ways:Direct flow mode, such as external gear pump;Port plate, such as vane pump, axial piston pump, etc.;
- Q: What is the lift off the dead center point? This is a straight mark about the water pump. What is the function and the relationship between the design head and the pump head? ThanksWhat exactly is the dead point lift? What's the function of this indicator?
- The dead point head is the measured head after the outlet valve is closed. Mainly on the lower reaches of the pump equipment, such as your dead center, the lift is 300 meters, that is, 3MPa
- Q: I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?
- (4) before installation, make sure all pipes connected with the pump should be clean, and no solid foreign bodies which may cause damage to the pump shall be allowed.(5) apply the blind flange or other things to the suction, exhaust or open pump to ensure that no sundries enter the pump cavity during the installation.(6) check whether the pump random data is complete and complete; whether the pump surface has obvious damage. Only with complete data, no obvious damage to the pump, you can continue to install.(7) the installation of centrifugal pump with the coupling of the hand when turning slowly rotating coupling or pulley, observe the pump rotation are stable, flexible and adjustable, the rotor parts have no jamming, the pump has no debris crash, bearing the operation is normal, with elastic suitability.
- Q: What is a positive displacement pump? He Weizheng displacement?
- Includes a pump housing (10), a pump chamber (24), the pump chamber has an entrance channel (21) and an outlet check valve (17) export control channel (28), a displacement member (13), the definition of the pump cavity in a direction of movement in (24) and in a stroke section in the pump cavity (S) in reciprocating motion
- Q: How high can the pneumatic diaphragm pump be?
- Pump made of polyvinylidene fluoride (PVDF) material two, the series of pneumatic diaphragm pump belongs to the fluorine plastic pneumatic diaphragm pump is also known as the corrosion products of pneumatic diaphragm pump, diaphragm liquid contact using PTFE material, using PVDF material produced by pneumatic diaphragm pump is mainly used in corrosive the pH, mainly used for chemical liquid conveying multiple solvent, corrosion resistance effect is very good. The series of fluorine plastic pneumatic diaphragm pump in high temperature less than 93.3 degrees.POM pump material also has good resistance to solvent and abrasion resistance, low friction resistance, moisture absorption is also low, the highest temperature of such pumps within 65.5 degreesPolytetrafluoroethylene (PTFE) membrane corrosion resistance is very good, in addition to liquid metal lithium, potassium fluoride, sodium fluoride, three chlorine, three fluoride high temperature oxygen, high flow rate, almost all of the chemical liquid transport (including concentrated nitric acid and aqua regia), PTFE material the maximum temperature to 176.6 degrees. However, for the diaphragm pump product as the diaphragm moves back and forth in work, we suggest that at a temperature of 120 degrees, the prerequisite is the pump body pump must be made of metal material and plastic material. The pump is the pump of PVDF material temperature is highest in less than 93.3 degrees.
- Q: Is the centrifugal pump large or small?
- When the liquid is lowered at a certain temperature to the vapor pressure at this temperature, the liquid bubbles. The phenomenon of producing bubbles is called cavitation. When the bubbles are flowing to the high pressure, the volume of the bubbles is reduced so that they are destroyed. This due to the pressure of rising bubbles disappear in the liquid in the phenomenon called cavitation bubble collapse. The local pump is in operation if the over-current part (usually the impeller blade inlet somewhere later) for some reason, the absolute pressure of pumping the liquid was reduced to liquid vapor pressure temperature, liquid vaporization began there, produce a lot of steam bubble formation, when the liquid contains a lot of bubbles by forward high pressure impeller Zone, high pressure liquid around the bubbles in the bubble decreases drastically and rupture. Condensation in the bubble burst and the liquid particle at high speed to fill a hole in this moment has a very strong effect of water hammer and the impact of high frequency against the metal surface, the impact stress of hundreds to thousands of atmospheric pressure, impact frequency can be up to tens of thousands of times per second, serious breakdown when the wall thickness will be. The process of cavitation in a pump is caused by the bursting of bubbles and bubbles in the water pump and the destruction of the over-current components. Water pump cavitation, in addition to the over-current components will have a destructive effect, but also produce noise and vibration, and lead to the performance of the pump down, seriously when the pump will be interrupted liquid, can not work properly.
- Q: What is the nominal pressure of the hydraulic pump and hydraulic motor?
- Related concepts of hydraulic motorsFlow theoretical volume refers to the volume of oil inhaled in unit time without leakage.
