Description
Technical field
The present invention relates to a kind of reciprocating pump structure, and power end component and use more particularly to a kind of reciprocating pump should
The multi-cylinder reciprocating pump of component.
Background technology
For general horizontal reciprocating pump hydraulic-end in the front of power end, vertical reciprocation pump power end is bent in the lower section of fluid end
Axle acting is also only a fluid end service, and the reciprocating plunger pump installation of this structure is limited by the field.Back and forth
The formula plunger efficiency of pump is higher than efficiency of centrifugal pump, and the position of centrifugal pump is gradually instead of in water supply field, but due to reciprocating type plunger
Pump position dimension and inadaptability in structure field requirement, can not be suitable for high-rise building water system.It is a people that building, which supply water,
With, industrial multi-field high rise building water supply Energy-saving Projects, while it is also the huge engineering of a popularization amount.Reciprocating plunger pump
Operational efficiency ＞ 88%, and the efficiency of rotary and centrifugal type multistage water supply pump typically up in 75% practical application up to
65%, the two energy-conservation differs greatly, and the especially building number of plies is more than 60 layers, typically in one pump transfer of middle (30 layers) settings
Stand, now, the efficiency of centrifugal pump can be lower.Reciprocating plunger pump sets a pumping plant on ground with regard to much of that, because of reciprocating type plunger
Pump is displacement pump, so pressure and flow are mutually non-interference, and both of which can be realized by VFC, pass through electrodeless tune
Speed variator needs how much water supplies how much water.Currently in 13 this innovation driving, energy-saving overall situation, innovation optimization
