渣漿泵的性能參數(shù)表:渣漿泵主要性能參數(shù)有哪些
渣漿泵的主要性能參數(shù)是表示渣漿泵工作性能的參數(shù),主要包括流量Q,揚程H,轉(zhuǎn)速n,功率P,效率η,汽蝕余量(NPSH)以及允許吸上真空高度Hs
顧名思義就是指單位時間內(nèi)渣漿泵排除液體的數(shù)量
有兩種表示方法分別是體積流量Q和重量流量Qc
體積流量的單位:m3/h、L/s
重量流量的單位:t/h、kgf/h
體積流量Q和重量流量Qc的關(guān)系是:
Qc=γQ
γ表示漿體的比重(重度)kgf/m3

常規(guī)理解為能夠達到的輸送高度
主要來表示泵軸每分鐘旋轉(zhuǎn)的次數(shù),單位是r/min
渣漿泵的功率包括:
有效功率Pu(輸出功率)
是單位時間內(nèi)對流經(jīng)該泵流體所做的功
軸功率P(輸入功率)
指原動機輸送給泵軸的功率
配用功率Pg
指原動機額定輸出功率,一般配用功率要比軸功率要大一些
泵的輸入功率與輸出功率之差為泵內(nèi)的功率損失,之比為渣漿泵的效率η
為了使渣漿泵在運行中不發(fā)生汽蝕
渣漿泵的進口處的液體所具有超過汽化能力的富余能量

渣漿泵的性能參數(shù)表:渣漿泵主要需要什么性能參數(shù)
渣漿泵主要需要什么性能參數(shù)
表示泵工作性能的參數(shù)叫做泵的性能參數(shù),常有流量Q,揚程H,轉(zhuǎn)速n,功率P,效率η,汽蝕余量(NPSH) 或允許吸上真空高度[H,] 等。
一、流量Q
泵在單位時間內(nèi)排出液體的數(shù)量,有體積流量Q和重量流量Qc兩種:
體積流量Q的單位: m3/h; m3/s; L/s等。
重量流量Qc的單位: tVh; kgf/s。
重量流量Qc和體積流量Q的關(guān)系為:
二、揚程H
單位重量液體通過泵后能量的增加值,即等于泵的出口總水頭與入口總水頭的代數(shù)差。單位為米水柱(mH20)。
功率P
泵的功率包括有效功率Pu (或稱輸出功率),軸功率P (或稱輸入功率),配用功率Pg三種。
1.泵的有效功率P。(輸出功率)
是單位時間內(nèi)對流經(jīng)該泵流體所做的功,稱有效功率Pu或稱輸出功率、水功率。
Pu=pgQvH/1000
式中 Pu—-泵的有效功率, kW;
Qv—-泵的體積流量, m3/s;
H—-泵的總揚程,m;
p—-被輸送液體的密度,kg/m3;。
2.軸功率P (輸入功率)
是指原動機輸給泵軸的功率,稱軸功率P或稱輸入功率。
泵的輸入功率和輸出功率之差即為泵內(nèi)的損失部分,之比為泵的效率η。
P=Pu/η= pgQvH/1000η
式中η泵的效率 ,%。
3.配用功率Pg
是指原動機額定輸出功率。考慮到泵在非設(shè)計工況下運行時軸功率增大或泵在長時間運行后效率下降或其他故障時軸功率增大等因素,所以配用功率比軸功率要大一些,需有一個儲備系數(shù)k。
Pg=kP
式中 k—-儲備系數(shù)
儲視功率的大小采用不同的儲備系數(shù),見圖2-28.
五、泵效率η
泵的有效功率Pu與軸功率P之比,用百分數(shù)表示:

What are the main performance parameters of slurry pump
The parameters indicating the working performance of the pump are called the performance parameters of the pump, including flow Q, head h, rotating speed n, power P, efficiency η, NPSH or the allowable vacuum height [h,], etc.
I. flow Q
The quantity of liquid discharged by the pump in unit time includes volume flow Q and weight flow QC:
Unit of volume flow Q: m3 / h; m3 / S; L / s, etc.
Unit of weight flow QC: TVH; kgf / s.
The relationship between weight flow QC and volume flow Q is as follows:
II. Lift H
The increment of energy after the unit weight liquid passes through the pump is equal to the algebraic difference between the total head at the outlet and the total head at the inlet of the pump. The unit is m water column (mh20).
Power P
The power of the pump includes effective power Pu (or output power), shaft power P (or input power) and power PG.
1. Effective power P of pump. (output power)
It is the work done to the fluid flowing through the pump in unit time, which is called effective power Pu or output power and water power.
Pu=pgQvH/1000
Where Pu is the effective power of pump, kW;
QV —- volume flow of pump, m3 / S;
H —- total head of pump, m;
P —- density of delivered liquid, kg / m3;.
2. Shaft power P (input power)
It refers to the power transmitted by the prime mover to the pump shaft, which is called shaft power P or input power.
The difference between the input power and output power of the pump is the loss part in the pump, and the ratio is the efficiency η of the pump.
P=Pu/η=pgQvH/1000η
Where, the efficiency of η pump,%.
3. Power PG
It refers to the rated output power of prime mover. In consideration of the factors such as the increase of shaft power when the pump is running under non design conditions, the decrease of pump efficiency after a long time of operation or the increase of shaft power when other faults occur, the matching power is larger than the shaft power, and a reserve coefficient K is required.
Pg=kP
Where k — reserve coefficient
Different reserve coefficients are used for the storage of apparent power, as shown in Figure 2-28
V. pump efficiency η
The ratio of the effective power Pu of the pump to the shaft power P, expressed as a percentage:
Η=PU / P * 100% slurry pump manufacturer
