Detailed Description
The following description is only of the preferred embodiments of the present invention, and the scope of the present invention should not be limited to the examples, but should be construed as falling within the scope of the present invention. It should also be noted that modifications and adaptations to those skilled in the art without departing from the principles of the present invention are intended to be comprehended within the scope of the present invention.
The water pump caused by high altitude allows the suction vacuum to be changed, and the adverse effects on the pump lift, pump house and pool design of the water pump can be seen from the table,
| altitude (m) | 0 | 200 | 300 | 500 | 700 | 1000 | 1500 | 2000 | 3000 | 4000 |
| Atmospheric pressure (m water column) | 10.3 | 10.1 | 10.0 | 9.7 | 9.5 | 9.2 | 8.6 | 8.4 | 7.3 | 6.3 |
| Maximum water absorption height (m) | 6.0 | 6.0 | 6.0 | 5.7 | 5.5 | 5.2 | 4.6 | 4.4 | 3.3 | 2.3 |
In a high-rise residence in a Xining region with a local altitude of about 2000m, an outdoor fire-fighting water pool for taking water from a fire-fighting truck should ensure that the height between the lowest water level of the outdoor fire-fighting water pool and the central line of a fire-fighting water sucking pipe in the fire-fighting truck is not greater than the maximum water sucking height of the place where the fire-fighting water pump is located, and the maximum water sucking height of the water pump is about 4.4 m.
The pump manufacturer can only give H, values, but not directly H g Values. Because each pump has different use conditions, the arrangement condition of the suction pipeline is different, and the suction pipeline has different u1/2g
Sum sigma H j The value, therefore, can only be determined by calculation by the usage unit depending on the specific arrangement of the suction line.
The term "H" as used herein refers to a value obtained by setting the atmospheric pressure to 10mH2O and the water temperature to 20C. If the conditions of the pump are different from the conditions, the H value given on the sample is converted into H' value under the operating conditions, and the conversion formula is
H’=Hg+(H。- 10)- (Hg-0.24)
In the middle of
H, allowing suction of vacuum height, mH, when delivering water under an operating condition 2 O;
H. -allowed suction vacuum height given in pump sample, mH 2 0;
H, atmospheric pressure at the working site of a pump, mH 2 0; .
H, saturated vapor pressure of water at a pump operating temperature, mH 2 O;
Saturated vapor pressure of water, mH, of 0.24 2 O。
The higher the elevation of the pump installation site, the lower the barometric pressure, and the lower the vacuum allowed to suck up. The higher the temperature of the liquid to be delivered, the higher the corresponding saturation vapor pressure, and the lower the allowable suction vacuum height of the pump. The pump does not cavitation and the lowest absolute pressure allowed at its inlet (expressed as vacuum) is expressed as the liquid column height, called the allowed suction vacuum height of the pump.
