Abstract
The invention relates to a single-output volumetric high-pressure boiler pump assembly used for water feed of a high-pressure boiler, and belongs to the fields of chemical engineering, metallurgy, thermal power and the like. The single-output volumetric high-pressure boiler pump assembly comprises a hydraulic control system (8), a drive oil cylinder assembly (7), a water feed pump assembly (6), water inlet and outlet one-way valve assemblies (5 and 4), water inlet and outlet pipe assemblies (3 and 2), a pipeline pressure-stabilizing device and the like. Compared with a centrifugal type (multi-stage) water feed pump assembly, the single-output volumetric high-pressure boiler pump assembly has the advantages of being lower in energy consumption, higher in water feed volume fraction, longer in service life, easier and more convenient to use, easier to maintain and the like.
Description
Technical field
The present invention relates to a kind of single delivery volume formula pump group part for high pressure boiler water supply, belong to the technical fields such as chemical industry, metallurgy, thermoelectricity.
Background technology
At present, when the industries such as chemical industry, metallurgy, thermoelectricity are steam boiler conveying high-pressure water, all using centrifugal (multistage) feedwater pump group part, generation centrifugal force is rotated by Motor drive multi-stage impeller and realizes the extraction of low pressure water and the conveying of water under high pressure.The impeller of such pump is larger with the gap of the pump housing, and the swept volume rate of pump is relatively low, energy consumption is higher, aggregate efficiency≤60%.The hydraulic pressure of conveying is higher, leads to impeller often fragile, service life is shorter, maintenance cycle is shorter, costly.Motor rated power is larger.When needing higher discharge pressure, just need multiple stage centrifugal pump to be used in series, more take electric, poorly efficient.
Content of the invention
For above-mentioned prior art, the technical problem to be solved in the present invention is that when providing a kind of work, pump plot ratio is higher, energy consumption is lower, work efficiency is higher, the hydraulic pressure of conveying is higher, the life-span is longer, using feedwater pump group part that is easier, being more readily maintained.
For solving above-mentioned technical problem, the invention provides a kind of single delivery volume formula high pressure water feeding pump for boiler assembly, by hydraulic control system, hydraulic cylinder assembly, feedwater pump assembly, intake-outlet check valve assembly, water inlet pipe and water outlet pipe assembly, pipeline voltage stabilizer etc. is driven to form.Wherein: drive hydraulic cylinder assembly by driving cylinder block, drive oil cylinder piston, drive oil cylinder oil inlet and outlet etc. to form.Feedwater pump assembly is made up of the feed pump pump housing, feedwater pump piston, feedwater sucker rod etc..Oil cylinder piston is driven to couple for an entirety with feedwater sucker rod, feedwater pump piston.
Specific embodiment
As shown in Figure 1, during work, there is provided power oil by hydraulic control system 8, oil cylinder piston 7d is driven to drive feedwater pump piston 6c to move back and forth, the corresponding volume changing feed pump working chamber 6a, drive intake-outlet check valve 3,4 accordingly constantly to close and open, realize constantly extracting low pressure water from water source by water inlet pipe component 3, the water after pressurizeing is transported to by boiler by one end of the outlet pipe component 2 of three-port structure.The other end of outlet pipe component 2 is connected with pipeline voltage stabilizer 1, to guarantee the stable water pressure exporting, reduces the impact shock to pipeline and equipment for the water under high pressure, realizes flow trim.
Piston is very little with the gap of the pump housing, will not leak, and makes the plot ratio up to >=95% of pump, utilization rate of electrical is higher, and energy consumption is relatively low, send water in hgher efficiency, and assembly service life is longer, and maintenance cost is relatively low.
This feed pump has following characteristics:
1. it is used for the high pressure steam boiler feedwater in the industry such as chemical industry, metallurgy, electric power.
2. feed pressure is up to 50mpa, and common centrifugal pump is unable to reach high pressure.
3. feed pump pistons work is driven by hydraulic drive.
4. energy consumption is lower, feedwater plot ratio is higher, the life-span is longer, use easier, more easy care.
Brief descriptionFig. 1 is the structural representation of the present invention.
Claims (2)
