Abstract

The utility model relates to a vertical mud pump, which is composed of a supporting part, a rotor part, and a seal part. The utility model is characterized in that an easy damaged seal of a bearing is sealed by a soft filler mode, a skeletion oil seal mode, and an end surface seal mode which exist jointly; the middle between a soft filler and a skeletion oil seal are divided into two bodies, a water blocking ring is added between the two bodies to reduce the pressure of overflowed mud in a pump cavity, and thus, the mud can not enter a bearing chamber along a pump shaft to damage a bearing. A large stopping opening is adopted between a screw line-shaped pump body and a rear cover. The bearing chamber adopts a through hole. The number of blades in a semi-open impeller is four. The utility model has the advantages of increased reliability, extended service life, increased work efficiency, and convenient installation and maintenance.

Description

A kind of novel vertical slurry pump

The utility model belongs to water conservancy machinery.

Along with the develop rapidly of national economy, administer the river course, to draw engineering desilting workloads such as yellow irrigation, domestic water and excavation pond increasing.Current press for design a kind ofly be convenient to move, use reliable, the life-span is long, simple in structure, efficient is high, power consumption less, installation and maintenance make things convenient for.The novel water conservancy machinery that operations such as union is dug, adorns, fails, filled out, rammer are finished simultaneously.Yet the slurry pump that existing domestic engineering is used, abominable because of the operating conditions environment eventually, bearing seal is not well solved always, to pump work reliability and working life are reduced greatly.Inefficiency uses the maintenance cost height, brings great economic loss to the user.Though in the past few years through the parties concerned research side's of thinking solution, eventually because of poor effect, so still rest on original level.

The utility model purpose is to provide a kind of Trinitarian bearing seal form of soft packing, outside framework oil seal and end face seal that has.Adopt big seam between the spiral line type pump housing and the bonnet, bearing chamber adopts through hole, and the half-opened impeller intra vane is a kind of novel vertical slurry pump of four.Effectively solved the reliability of bearing seal, improved bearing working life, reduced maintenance cost, and give make, installation, maintenance brings great convenience.

When the utility model purpose was achieved in that pump work, pump chamber inner high voltage mud very easily upwards overflowed along the pump shaft that rotates, and soft packing at this moment compresses, and mud can not be flowed out.When damaging, soft packing can compress at any time and replenish.A small amount of mud is when pump shaft flows out, and water retaining ring can stop mud to continue to rise along pump shaft, and mud row is poured off to the outside.Defence line, second road outside framework oil seal, because of not being subjected to washing away of pump chamber internal pressure mud, wearing and tearing alleviate, and have prolonged working life.When the long-term outside framework oil seal that uses wore and tore, seal action was still played in the three lines of defence end face seal, and mud can not enter bearing chamber and damage bearing.Through the three lines of defence sealing, avoid entering mud in the bearing chamber, protected bearing not to be damaged, thereby prolonged the working life of bearing greatly.Adopt big seam between the spiral line type pump housing and the bonnet, half-opened impeller can be packed into from this end, the half-opened impeller of can packing into earlier during installation, after the spiral line type pump housing of packing into, reduced the spiral line type pump housing of packing into after, the difficulty that refills, tears open half-opened impeller.The half-opened impeller intra vane adopts four, has increased the active area of blade to liquid, and under the constant situation of motive force, working efficiency improves greatly.

The mode of the utility model because of having adopted unique soft packing, outside framework oil seal, three kinds of seal form of end face to coexist, and between soft packing and outside framework oil seal, be divided into two bodies, the centre adds a water retaining ring.Between soft packing and outside framework oil seal and pump shaft, adopt axle sleeve, protected pump shaft not frayed.The possibility of having avoided mud to enter bearing chamber to greatest extent when work has protected bearing not to be damaged, and has prolonged the working life of pump greatly, has improved working efficiency, has reduced maintenance frequency, has reduced user cost.Adopt big seam between the spiral line type pump housing and the bonnet, bearing chamber adopts through hole, brings great convenience for manufacturing, installation, maintenance.The half-opened impeller intra vane adopts four, thereby has improved working efficiency, has reduced user cost, reaches energy-efficient purpose.

The utility model concrete structure is provided by following examples and accompanying drawing.

Accompanying drawing is a whole-cutaway view of the present utility model.

Describe details and working condition in detail below in conjunction with this accompanying drawing according to the concrete structure that the utility model proposes:

The utility model is mainly by support unit: [1] [3] [4] [7] [13] [14], rotor part: [2] [6] [8] [10] [12] [15] [18] [19] [23], sealed member: [5] [9] [11] [20] [21] three parts such as [22] are formed.As shown in drawings.Support unit: the spiral line type pump housing [4] the left end protecgulum [1] of packing into, right-hand member pack into successively bonnet [3], bearing bracket stand [7], middle seat [13], motor cabinet [14].Is one with bolton with upper-part respectively behind pack into rotor part and sealed member.Rotor part: the left end of pump shaft [12] is packed into successively, and also usefulness nut [23] is fastening for bearing [19], axle sleeve [10], water retaining ring [8], protective shaft sleeve [6] and half-opened impeller [2].Right-hand member bearing [18], the pump connection device [15] of packing into successively, its middle (center) bearing [18] [19] is respectively charged into fixedly becomes fulcrum on motor cabinet [14] and the bearing bracket stand [7].Sealed member: soft packing [5] is packed in the filler chamber of bonnet [3], and aligns with Gland [22].Outside framework oil seal [9] and edge face sealing member [11] are respectively charged in the sealing seat [20], and wherein outside framework oil seal [9] is located with gland [21].Sealing seat [20] is fixed by bolts on the bearing bracket stand [7].

The utility model is such enforcement, and motor rotates during work, joins device [15], passes to pump shaft [12] drive half-opened impeller [2] rotation by Electricity Federation device [16], pump, produces centrifugal force.Mud enters in the spiral line type pump housing [4] by protecgulum [1], when the half-opened impeller [2] that process is rotated, kinetic energy and pressure can increase simultaneously, make mud pass through the spiral line type pump housing [4] outlet and discharge, be sent to the spoil ground, finish dig, adorn, fail, fill out, operation task such as rammer.
