Abstract
The invention provides a hard alloy amphibious sand pump capable of being idled and connected in series. The sand pump is characterized in that the cylindrical surfaces of first rotating ring drive bodies where a plurality of spring installation holes of a mechanical seal are located are provided with ring-shaped grooves which are used for thin wires or thin steel wires to surround the groove bottoms and then be tied and fall in the open space between the steel wires of springs to block the springs so that the springs do not drop out; and the ring-shaped grooves are arranged at the bottoms of the spring installation holes and are communicated with the spring installation holes. The sand pump has the following advantages that the improved mechanical seal is easy to manufacture, is convenient to install and dismantle, has an ideal effect and can pump water and drain sand in deeper water.
Description
Technical field
The present invention relates to a kind of cemented carbide idle running can to connect amphibious husky pump, it is land and amphibious type water pump dual-purpose under water, is applicable to carry in liquid containing the vertical pump of the sand-discharging submerged pump of solid abrasive particles or land.
Background technique
Prior art, " vertical pump for mine " has three patent of invention: ZL200410078876.4, ZL200410078879.8, ZL200410078880.0.
The pressure at both sides frequent variations of single mechanical end face seal or by the tripartite pressure frequent variations of double mechanical seal, can cause cause thermal damage even cracked, directly affect sealing effect and the life-span of vertical pump for mine.Such as: water level 100 meters drops to several meters, the pressure of the vertical pump for mine in shaft bottom drops to almost nil from 1MP.And for example: when the motor temperature of heating is raised to 180 DEG C by normal temperature, body internal pressure is raised to 1MPa saturated vapor from zero.This two pressure are replaced to the phenomenon of frequent variations, also do not retrieve desirable solution at present, therefore, application area and the working life of submersible pump and vertical pump for mine are restricted always.
Summary of the invention
The object of the invention is: for mining provides a kind of amphibian amphibious type vertical pump for mine upgrading products---cemented carbide idle running can be connected amphibious husky pump, its mechanical seal can when the cavity pressure of mechanical seal isolation alternately changes frequently, harmful effect can not be produced to seal face, still can work safely and reliably, and the new mechanical seal improved is easy to manufacture, installing/dismounting is easier, can overcome current shortcoming and defect.
The cemented carbide idle running of the present invention technological scheme that amphibious husky pump adopts of can connecting is: the cylndrical surface of the first rotating ring transmission body at multiple spring mounting hole places of mechanical seal have for fine rule or finer wire bottom land around after knotting and the space can fallen between the steel wire of spring and steel wire makes its unlikely circular groove dropped out to spring of blocking again.Circular groove leaves the bottom at spring mounting hole and connects with all spring mounting holes.
Mechanical seal smooth driving pin be arranged on be arranged on the first rotating ring transmission body within the transmission pin-and-hole that can free in and out of pump shaft simultaneously the first rotating ring transmission body first transmission gap that can free in and out within time have and cover on can block and the gear cylinder that the driving pin installed within pump shaft transmission pin-and-hole and the first transmission gap is thrown out of after preventing from rotating outside the first rotating ring transmission body circumference.Gear cylinder can be the hood-like cylinder of thin-walled that the transmission body of double mechanical seal second rotating ring is extended.Gear cylinder can also be the hood-like cylinder of thin-walled that the sleeve end of following pump shaft rotation of single mechanical end face seal is extended.This one end of the hood-like cylinder of axle sleeve band thin-walled also has the pressure-bearing end face of holddown spring.The hood-like cylinder of thin-walled also has only circumferentially to be cut off, then the driver blade extend in the second transmission gap of the first rotating ring that curves inwardly.
The internal diameter of the stationary ring of high-abrasive material manufacture is identical or close with the external diameter of the stationary ring fitting seat installed in the mounting hole of frame, is provided with dismountable filling of filling this space and overlaps in the space between the bore area identical with rotating ring internal diameter at stationary ring to pump shaft surface.The transmission pin-and-hole that driving pin has the driving pin that the axial plane of pump shaft is opened to free in and out, fill the space of the accommodation self of the first transmission gap that driving pin that driving pin through hole and the first rotating ring transmission body that the driving pin that puts out can free in and out are opened can free in and out.Filling cover has the O shape on this mating face closed to enclose and O shape ring recess with the mating face of pump shaft.
Can the connect advantage of amphibious husky pump of cemented carbide idle running of the present invention is: achieve mechanical seal different cavity alternately frequent produce high pressure time, excessive pressure can not be produced at seal face, can work safely by held stationary.Meanwhile, the mechanical seal after improvement easy to manufacture, easy installation and removal, satisfactory for result, can to draw water in darker water sand discharge, the steam high pressure that sealed electric-motor inner chamber brings due to high temperature when sand discharge is transshipped can be resisted, the rigors of pressure frequent variations to mechanical seal can also be met.
