Abstract
The utility model discloses a hard alloy amphibious sand pump capable of spinning and being connected in series. A first movable ring is provided with a blocking cylinder of a transmission pin which can be thrown out when a check block covered outside the circumference of a first movable ring transmission body rotates. The blocking cylinder can be a thin-wall cover-shaped cylinder extended out of a transmission body of a second movable ring which adopts two-end-surface mechanical sealing. The hard alloy amphibious sand pump realizes the aims that when different cavities generate high pressure alternatively and frequently, a mechanical seal can not generate overlarge pressure at sealing end surfaces, so that the work can be kept to be stable and safe. Simultaneously, the improved mechanical seal is easy to manufacture, is convenient to install and dismantle, has an ideal effect, can be used for pumping water and discharging sand in deeper water, can resist steam high pressure in a cavity of a sealing motor caused by high temperature due to overload in sand discharging, and can meet the harsh requirements on the mechanical seal due to the frequent change of pressure.
Description
Technical field
The utility model relates to a kind of cemented carbide idle running amphibious husky pump of can connecting, and it is land and dual-purpose under water amphibious type water pump, is applicable to carry the sand-discharging submerged pump that contains solid abrasive particles in the liquid or land with upright pump.
Background technique
Existing technology, " vertical pump for mine " have 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 influences the sealing effect and the life-span of vertical pump for mine.For example: water level drops to several meters for 100 meters, and 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 was raised to 180 ℃ by normal temperature, the body internal pressure was raised to the 1MPa saturated vapor from zero.Replace the phenomenon of frequent variations for this two pressure, also do not retrieve desirable solution at present, therefore, the application area and the working life of submersible pump and vertical pump for mine are restricted always.
Summary of the invention
The purpose of the utility model is: for mining provides a kind of amphibian amphibious type vertical pump for mine upgrading products---the cemented carbide idle running amphibious husky pump of can connecting; When its mechanical seal can replace frequent variation at the cavity pressure that mechanical seal is isolated; Can not produce harmful effect, still can work safely and reliably, and new improved mechanical seal is easy to manufacture seal face; Installing/dismounting is easier, can overcome current shortcoming and defect.
The cemented carbide idle running of the utility model technological scheme that amphibious husky pump adopted of can connecting is: mechanical seal has when within smooth driving pin is installed in the transmission pin-and-hole that can free in and out of pump shaft, being installed within the first rotating ring transmission body, the first transmission gap that can free in and out of the first rotating ring transmission body simultaneously and covers on can block and prevent to rotate the retaining tube that the driving pin within the pump shaft transmission pin-and-hole and the first transmission gap, installed the back is thrown out of outside the first rotating ring transmission body circumference.The retaining tube can be the extended thin-walled cover of the transmission body shape cylinder of double mechanical seal second rotating ring.The retaining tube can also be the extended thin-walled cover of the sleeve end shape cylinder of following the pump shaft rotation of single mechanical end face seal.This end of axle sleeve band thin-walled cover shape cylinder also has the pressure-bearing end face of holddown spring.Thin-walled cover shape cylinder only also has to be cut off on circumference, the driver blade in the second transmission gap that extend into first rotating ring that curves inwardly again.
The cylndrical surface of the first rotating ring transmission body at a plurality of spring mounting holes place of mechanical seal have supply fine rule or finer wire bottom land around after again knotting and steel wire and the space between the steel wire that can the fall spring spring of blocking make its unlikely circular groove that drops out.This circular groove is opened in the bottom of spring mounting hole and with all spring mounting holes and is connected.
The internal diameter of the stationary ring of high-abrasive material manufacturing is identical or close with the external diameter of the stationary ring fitting seat of in the mounting hole of frame, installing, and the bore area identical with the rotating ring internal diameter at stationary ring is equipped with dismountable filling cover of filling this space in the space between the pump shaft surface.Driving pin has transmission pin-and-hole that the driving pin opened on the axial plane of pump shaft frees in and out, fill the space that holds self of the first transmission gap that the driving pin opened on the driving pin through hole that the driving pin that puts out can free in and out and the first rotating ring transmission body can free in and out.There is the O shape circle and O shape ring recess on this mating face of sealing on the mating face of filling cover and pump shaft.
Can the connect advantage of amphibious husky pump of the cemented carbide idle running of the utility model is: realized that mechanical seal in that different cavitys are alternately frequent when producing high pressure, can not produce excessive pressure at seal face, the purpose of can held stationary working safely.Simultaneously, the mechanical seal after the improvement easy to manufacture, easy installation and removal; Satisfactory for result; Can be in darker water the row of drawing water husky, can resist the sealed electric-motor inner chamber because the steam high pressure that high temperature brings during the husky overload of row can also satisfy the harsh requirement of pressure frequent variations to mechanical seal.
