Abstract
The invention relates to a new detachable direct connection horizontal single-stage pump. The single-stage pump consists of three parts, which are a pump, an elongated shaft motor and a pedestal, and is characterized in that the pump comprises a pump body, an impeller, a pump cover and a mechanical seal, wherein the part for mounting the elongated shaft motor of the pedestal is provided with a dovetail groove sliding guide rail; the pump body is fixedly arranged at one end of the pedestal by bolts; the bottom of the elongated shaft motor is provided with a dovetail groove; the dovetail groove at the bottom of the elongated shaft motor is formed in the dovetail groove sliding guide rail on the pedestal. The impeller, the pump cover, the mechanical seal and the elongated shaft motor are assembled into an integrated component. The single-stage pump has the advantages that the disassembly is flexible and convenient during maintenance or replacement of a spare part since a back opening door type structure is adopted, the maintenance or replacement of the spare part is also extremely easy and no special lifting appliance or personnel are required even if a high-power motor pump unit is arranged so that the maintenance time and cost are saved, the motor is in direct connection with the pump so that the middle structure is simplified and the stability of operation is enhanced, the pump has a simple structure and is easy to implement, the defects of the conventional direct connection single-stage pump are overcome and the requirements for field use of clients can be fully met.
Description
Technical field
The present invention relates to and a kind of new-typely just tear direct connection horizontal one-stage pump open.
Background technique
Conventional direct connection horizontal one-stage pump, pump one, is made up of pump, extension shaft motor, base three part.Pump structure comprises the component such as the pump housing, impeller, pump cover, mechanical seal.Pump is single absorption horizontal centrifugal pump, and the pump housing, pump cover two-part, from wheel backface subdivision, are rear opening structural type.Pump and motor coaxle, direct connection assembles, and has common base.(as shown in Figure 1), the extension shaft structure of this bearing structure is adopted can to there is following drawback:
This serial direct connection horizontal one-stage pump is back opening door structure, when maintenance or replacing accessory, can only by dismounting motor, and just can untie the pump housing after removing motor and carry out overhauling or changing accessory, if larger pump group, high power motor is joined by institute, and dismounting is mobile then quite difficult, lifting appliance and the personnel of specialty need be used, thus increase maintenance time and cost.
Summary of the invention
The object of this invention is to provide a kind of the new-type of common direct connection horizontal one-stage pump that be different from and just tear direct connection horizontal one-stage pump configuration formula open, this is new-type just tears direct connection horizontal one-stage pump open increases the application area of pump and uses flexibility, reduce maintenance or more time of exchange device and cost, fully meet the particular/special requirement of client.The present invention designs and a kind of new-typely just tears direct connection horizontal one-stage pump open, be made up of pump, extension shaft motor, base three part, it is characterized in that: pump comprises the pump housing, impeller, pump cover, mechanical seal formation, divide in floor installation extension shaft motor section and be provided with dovetail groove slide guide, the pump housing is bolted in base one end, the bottom of extension shaft motor is provided with dovetail groove, and the dovetail groove of the bottom of extension shaft motor is arranged in the dovetail groove slide guide on base.Impeller, pump cover, mechanical seal and extension shaft motor are assembled into an one-piece element.Advantage of the present invention adopts back opening door structure, and when maintenance or replacing spare part, dismounting is flexible, even join high-power electric pump group, maintenance or replacing spare part are also quite easy, do not need lifting appliance and the personnel of specialty, thus save maintenance time and cost; Motor and pump direct connection, simplify intermediate structure, enhance traveling comfort; Structure is simple, easily realizes, compensate for the deficiency of traditional direct connection single-stage pump, can fully meet curstomer's site usage requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
In figure, 11 pump housings, 12 impellers, 13 pump covers, 14 extension shaft motors, 15 bases.
Fig. 2 is structural representation of the present invention (pump housing and impeller, pump cover, mechanical seal and the separated state of extension shaft motor part).
In figure, 1 pump housing, 2 impellers, 3 pump covers, 4 extension shaft motors, 5 bases, 6 dovetail grooves, 7 dovetail groove slide guides, 8 bolts.
Below in conjunction with accompanying drawing and construction embodiment, detailed operation instruction is done to the present invention.
Embodiment
Be made up of pump, extension shaft motor, base three part in Fig. 2, it is characterized in that: pump comprises the pump housing, impeller, pump cover, mechanical seal formation, divide in floor installation extension shaft motor section and be provided with dovetail groove slide guide, the pump housing is bolted in base one end, the bottom of extension shaft motor is provided with dovetail groove, and the dovetail groove of the bottom of extension shaft motor is arranged in the dovetail groove slide guide on base.Impeller, pump cover, mechanical seal and extension shaft motor are assembled into an one-piece element.
Because the pump housing is that a separate part is bolted on base, impeller, pump cover, mechanical seal and extension shaft motor are assembled into an one-piece element and are arranged on dovetail groove slide guide, thus the one-piece element that impeller, pump cover, mechanical seal and extension shaft motor are formed can horizontally slip on dovetail groove slide guide.Must maintenance or when changing spare part, as long as back out the connection fastening piece of the pump housing and pump cover, pull open along dovetail groove slide guide the one-piece element that impeller, pump cover, mechanical seal and extension shaft motor form backward, so just achieve just tearing open of pump group.
Claims (2)
1. new-typely just tear direct connection horizontal one-stage pump open for one kind, be made up of pump, extension shaft motor, base three part, it is characterized in that: pump comprises the pump housing, impeller, pump cover, mechanical seal formation, divide in floor installation extension shaft motor section and be provided with dovetail groove slide guide, the pump housing is bolted in base one end, the bottom of extension shaft motor is provided with dovetail groove, and the dovetail groove of the bottom of extension shaft motor is arranged in the dovetail groove slide guide on base.
2. just tear direct connection horizontal one-stage pump open by one according to claim 1 is new-type, it is characterized in that: impeller, pump cover, mechanical seal and extension shaft motor are assembled into an one-piece element.
