Abstract
Provided are a single-stage single-suction sand pump sand suction device and a sand suction method. A conventional sand suction pump cannot be used to pump mediums whose viscosity is relatively large, and with increasing of liquid viscosity, lift and efficiency of the pump would rapidly reduce. The viscosity of the medium is limited within 114 CST. Requirements on radial gap and axial gap between the impeller and the pump body of the sand suction pump are relatively strict, so processing and assembling are difficult. The single-stage single-suction sand pump sand suction device comprises a regulating valve (10). The regulating valve is connected with a discharge pipe (9). The discharge pipe is connected with an exhaust port (8). The exhaust port is connected with a pump housing (2) through a pipeline. The pump housing is connected with a suction pipe (5). The suction pipe is connected with a connecting flange (11). The connecting flange is connected with a one-way bottom valve (6) through a pipeline. The single-stage single-suction sand pump sand suction device is suitable to pump various yellow sand and ore sand, and other mediums with strong abrasion.
Description
Technical field:
The present invention relates to a kind of one step single sucking sand pump inhale sand device and inhale sand method, adapt to the pump of various different working condition, such as transport acid, the various corrosive ore pulp of smelting industry, all kinds of sewage of environmental protection industry (epi) etc., not only corrosion-resistant but also wear-resistant, use scope is very extensive.
Background technology:
Mortar pump, refers mainly to the water pump for carrying mortar, generally based on centrifugal pump.Sand pump is mainly in the majority in seabed placer, and sand taken out by river levee.The more meaning of mortar pump refers to mortar, inefficient, the highest less than 55%, and the efficiency of traditional Sand pump, at 20-40%, therefore hampers it and develops to high-power direction.Traditional Sand pump can not be used for pumping the medium that viscosity is bigger, because of along with stringy increase, pump lift and efficiency meeting dramatic drop-off, the viscosity of medium is limited within 114 centistokes, and radial clearance and the requirement of axial gap between Sand pump impeller and the pump housing bring certain difficulty more sternly to processing and assembly technology.
Summary of the invention:
It is an object of the invention to provide a kind of one step single sucking sand pump inhale sand device and inhale sand method.
Above-mentioned purpose is realized by following technical scheme:
A kind of one step single sucking mortar pumping sand device, its composition includes: regulate valve, described adjustment valve is connected with discharge line, described discharge line is connected with outlet, described outlet is connected with pump case by pipeline, described pump case is connected with intake line, and described intake line is connected with adpting flange, and described adpting flange is connected with one-way bottom valve by pipeline.
Sand device inhaled by described one step single sucking sand pump, and described pump case is internally installed impeller, pump shaft, and described impeller is connected with described pump shaft, and described pump case is connected with suction inlet.
Sand device inhaled by described one step single sucking sand pump, and described unidirectional base valve is connected with filter screen, and described filter screen surrounding has processed one group of bar hole uniformly.
Sand device inhaled by described one step single sucking sand pump, and described filter screen sucks the water in sand pond and impurity, enters into described intake line by pipeline, and described intake line is entered in the pump housing by suction inlet.
The suction sand method of sand device inhaled by described one step single sucking sand pump, the method comprises the steps: that mortar pump is operationally, rely on the impeller of high speed rotating, liquid obtains energy to improve pressure under centrifugal inertial force effect, mortar pump is before work, the pump housing and back with water inlet line must fill liquid medium, prevent cavitation from occurring, when impeller quick rotation, blade promotes that medium quickly rotates, the medium rotated flies out under the influence of centrifugal force from impeller, after water in pump is spilled over, impeller central portion forms vacuum area, one side constantly sucks liquid, one side constantly gives again the certain energy of liquid sucked, liquid is discharged, mortar pump just so continuously works.
Beneficial effects of the present invention:
1. the present invention in uniform temperature and concentration range resistant to various Korrosionsmediums (acid, alkali, salt) and organic solvent, 80 kinds of organic solvents of 20 DEG C and 90 DEG C impregnate 30d, appearance is without any anomalism, and other physical property also has almost no change.
The present invention adopts ultra-high molecular weight polyethylene (UHMW-PE) chemical property extremely stable, is therefore also suitable for using in food service industry.Safe and reliable, decompose without toxin, ultra-high molecular weight polyethylene impact energy absorbability is peak in plastics, sound-deadening properties good, thus reducing the noise that liquid flowing produces in course of conveying to greatest extent.
The coefficient of friction of the inside of the present invention is for being only 0.07-0.11, therefore there is self lubricity, when water lubrication, its coefficient of kinetic friction is at half than PA66 and polyformaldehyde (POM), when to slide or during rotation formula work, also better than steel and pyrite have added the lubricity after lubricating oil.
The present invention has innovation in the Hydraulic Design, structural design, flow passage components adopt the high-chromium wear-resistant Alloys Casting of anti scuffing, there is the features such as efficient, energy-conservation, wear-resisting, reliable, it is suitable for the conveying strong abrasion containing solid particle, mortar, mortar, mortar, slag etc., the solid-liquid mixed concentration of conveying can reach 60%, being more satisfactory adopt sand, take out sand, send sand equipment, user can adopt the mode of unit or multimachine series operation to reach remote construction according to actual condition.
