Description
Technical field：
The present invention relates to a kind of double list mortar pump sand removing devices with continuous work and suction sand method, adapt to the pump of a variety of working conditions, such as the various corrosive ore pulps of transport acid, smelting industry, all kinds of sewage of environmental protection industry (epi), not only corrosion-resistant but also wear-resistant, quite varied using scope.
Background technology：
Mortar pump, refers mainly to the water pump for conveying mortar, typically based on centrifugal pump.Sand pump is main in the majority in seabed placer, and river levee takes out sand.The more meanings of mortar pump refer to mortar, less efficient, not more than
55%
, the efficiency of traditional Sand pump exists
20-40%
, therefore hamper it and develop to high-power direction.Traditional Sand pump can not be used for pumping the larger medium of viscosity, and because that can be drastically reduced with the lift and efficiency of the increase of liquid viscosity, pump, the viscosity of medium is limited in
114
Within centistoke, the requirement of radial clearance and axial gap between Sand pump impeller and the pump housing more sternly brings certain difficulty to processing and assembly technology.
The content of the invention：
It is an object of the invention to provide a kind of double list mortar pump sand removing devices with continuous work and suction 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：Regulating valve, described regulating valve is connected with discharge line, described discharge line is connected with outlet, described outlet is connected by pipeline with pump case, described pump case is connected with intake line, described intake line is connected with adpting flange, and described adpting flange is connected by pipeline with one-way bottom valve.
Described double list mortar pump sand removing devices with continuous work and sand method is inhaled, impeller, pump shaft are installed inside described pump case, described impeller is connected with described pump shaft, and the pump case is connected with suction inlet.
Described double list mortar pump sand removing devices with continuous work and sand method is inhaled, described unidirectional base valve is connected with filter screen, and described filter screen surrounding is uniformly machined with one group of bar hole.
Described double list mortar pump sand removing devices and suction sand method, water and impurity in described filter screen suction sand pond with continuous work, described intake line is entered into by pipeline, and described intake line is entered in the pump housing by suction inlet.
Described double list mortar pump sand removing devices with continuous work and sand method is inhaled, the method comprises the following steps：Mortar pump is operationally, by the impeller of high speed rotation, 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 medium to rotate quickly, the medium of rotation flies out from impeller under the influence of centrifugal force, after water in pump is spilled over, impeller central portion forms vacuum area, simultaneously constantly suck liquid, give simultaneously and constantly the certain energy of liquid of suction, liquid is discharged, mortar pump just so continuously works.
Beneficial effects of the present invention：
1.
The present invention is resistant to various Korrosionsmediums in uniform temperature and concentration range
(
Acid, alkali, salt
)
And organic solvent,
20℃
With
90℃
's
80
Plant dipping in organic solvent
30d
, without any abnormal phenomena, other physical properties also have almost no change appearance.
2.
The present invention uses ultra-high molecular weight polyethylene
(UHMW-PE)
Chemical property is extremely stable, therefore is also suitable for being used in food service industry.It is safe and reliable, to be decomposed without toxin, ultra-high molecular weight polyethylene impact energy absorbability is peak in plastics, sound-deadening properties good, so as to reduce the noise of liquid flow movable property life to greatest extent in course of conveying.
3.
The coefficient of friction of inside of the invention is for only
0.07-0.11
, therefore with self lubricity, under the conditions of water lubrication, its coefficient of kinetic friction ratio
PA66
And polyformaldehyde
(POM)
It is at half, when being worked with slip or rotation formula, has added the lubricity after lubricating oil also good than steel and brass.
4.
The present invention has innovation in terms of the Hydraulic Design, structure design, flow passage components are cast using the high-chromium wear-resistant alloy of anti scuffing, with efficient, energy-conservation, it is wear-resisting, reliable the features such as, it is adapted to strong abrasion of the conveying containing solid particle, mortar, mortar, mortar, slag etc., the solid-liquid mixed concentration of conveying can reach
60%
, be it is more satisfactory adopt sand, take out sand, send sand equipment, user can reach remote construction according to actual condition by the way of unit or multimachine series operation.
