Abstract
The invention provides a hard alloy amphibious sand pump capable of being idled and connected in series. A first rotating ring is provided with a blocking drum which covers the circumference of a first rotating ring drive body and blocks a drive pin which will be thrown out during rotation. The blocking drum can be a thin-wall cover-shaped drum extending from a drive body for mechanically sealing a second rotating ring at double end faces. The sand pump has the following advantages that the aims that the mechanical seal can not generate too high pressure on the seal face when different cavities alternate and frequently generate high pressure and can keep stable and safe operation are achieved; and meanwhile, the improved mechanical seal is easy to manufacture, is convenient to install and dismantle, has ideal effects, can pump water and drain sand in deeper water, can resist the high temperature of steam brought by high temperature during drained sand overload in seal motor inner cavities and can meet the extreme demands of frequent variation of pressure.
Description
Technical field
The present invention relates to a kind of cemented carbide idle running amphibious husky pump of can connecting, it is land and dual-purpose amphibious type water pump under water, is applicable to carry the sand-discharging submerged pump that contains solid abrasive particles in the liquid or land with vertical pump.
Background technique
Prior art, " 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 affects sealing effect and the life-span of vertical pump for mine.For example: 100 meters of water levels drop to several 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, application area and the working life of submersible pump and vertical pump for mine are restricted always.
Summary of the invention
The objective of the invention 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 alternately change frequently at the cavity pressure of mechanical seal isolation, can not produce harmful effect to seal face, still can work safely and reliably, and new improved mechanical seal 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: mechanical seal have when within smooth driving pin is installed in the transmission pin-and-hole that can free in and out of pump shaft, being installed in simultaneously within the first rotating ring transmission body first transmission gap that can free in and out of the first rotating ring transmission body cover on outside the first rotating ring transmission body circumference can block and prevent from rotating after the gear cylinder that is thrown out of of the driving pin within pump shaft transmission pin-and-hole and the first transmission gap, installed.The gear cylinder can be the hood-like cylinder of the extended thin-walled of transmission body of double mechanical seal the second rotating ring.The gear cylinder can also be the hood-like cylinder of the extended thin-walled of sleeve end of following the pump shaft rotation of single mechanical end face seal.This 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 only also has to be cut off at circumference, the driver blade in the second transmission gap that extend into the 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 for fine rule or finer wire bottom land around after again knotting and can fall the steel wire of spring and the spring of blocking of the space between the steel wire makes 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 installing in the mounting hole of frame, 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 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 cemented carbide idle running of the present invention is: realized that mechanical seal is alternately frequent when producing high pressure at different cavitys, 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, the sand discharge of can drawing water in darker water can be resisted the sealed electric-motor inner chamber because the steam high pressure that high temperature brings during the sand discharge overload can also satisfy the pressure frequent variations to the harsh requirement of mechanical seal.
