Detailed Description
The following description is only a preferred embodiment of the present invention, and the protection scope is not limited to the embodiment, and any technical solution that falls under the idea of the present invention should fall within the protection scope of the present invention. It should also be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention.
The change in the height of the vacuum that the pump allows to suck due to the high altitude, has adverse effects on the design of the pump head, the pump room and the water tank, as 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 area with local elevation of about 2000m, an outdoor fire pool for a fire truck to take water should ensure that the minimum water level of the outdoor fire pool and the central line of a suction pipe of a fire pump in the fire truck are not more than the maximum water absorption height of the location of a fire pump, and the maximum water absorption height of the water pump is about 4.4 m.
The pump manufacturer can only give H, the value, but not directly H g The value is obtained. Because each pump has different use conditions, the arrangement conditions of suction pipelines are different, and the u1/2g is different
Sum-sigma H j The value Hg can therefore only be determined by calculation from the unit of use, depending on the particular arrangement of the suction line.
H given in the pump sample or specification means a value in a state where the atmospheric pressure is 10mH2O and the water temperature is 20C. If the conditions of use of the pump differ from these conditions, the H value given on the sample is converted into the H' value under the operating conditions by the conversion formula
H’=Hg+(H。- 10)- (Hg-0.24)
In the formula
H, allowing the suction of vacuum level, mH, when water is delivered under operating conditions 2 O;
H, -allowed suction of vacuum height given in pump sample, mH 2 0;
H, atmospheric pressure at the working site of the pump, mH 2 0; .
H, saturated vapor pressure of water at one pump operating temperature, mH 2 O;
Saturated vapor pressure of 0.24 water, mH 2 O。
The higher the altitude at which the pump is installed, the lower the atmospheric pressure, and the smaller the suction vacuum height is allowed. If the temperature of the delivered liquid is higher, the corresponding saturated vapor pressure is higher, and the allowable suction vacuum height of the pump is smaller. The pump is not cavitated and the lowest absolute pressure allowed at its inlet (expressed as vacuum) is expressed as the liquid column height, referred to as the allowed pull-up vacuum height of the pump.
It can be seen from the data that the outdoor fire pool at high altitude needs to be lifted up properly to supply the fire truck with the water, so as to effectively provide the normal water supply operation of the fire truck. The height difference between a water pumping hose of a general fire truck and an outdoor water pool is 1m, the maximum height of water which can be sucked by the pump in the area with the altitude is 3.4m, the problem that the water level which cannot be sucked at the bottom of the outdoor fire pool can only be effectively solved through other means, and the water level at the depth of 8-15m of the fire pool is adopted to be pulled up to adapt to a fire water intake for convenient taking.
