Abstract
The invention discloses a method and structure for reducing abrasion of a sand pump of a sandblasting machine. According to the method and structure for reducing the abrasion of the sand pump of the sandblasting machine, an impeller mechanism of the sandblasting machine is adjusted, a low-pressure area is made to be connected to the center area of the back side of an impeller; because a gap of a transmission shaft and a sand pump sand shell is located in the low-pressure area, gaps between shaft shells are in a negative pressure suction-in state, and sand water cannot be blasted out; and thus, it is not needed to weld a baffle on the transmission shaft, a motor cannot be damaged, and the overall service life of the sand pump is remarkably prolonged. According to the method and structure for reducing the abrasion of the sand pump of the sandblasting machine, the structure is simple, cost is low, and the using effect is ideal.
Description
Technical field
The present invention relates to mechanical field, especially a kind of method and structure for reducing the abrasion of sand-blasting machine sand pump.
Background technology
At present, sand pump generally uses centrifugal pump, and sand pump housing, impeller and blade adopt the lost material of resistance to sand
Polyurethane is manufactured, as shown in Fig. 2 when power transmission shaft impeller rotates at a high speed, sand water is dropped on side and forms higher-pressure region by blade,
The outlet of sand pump is arranged on higher-pressure region, and in centre low-pressure area is formed, therefore sand water inlet is arranged on low-pressure area.And sand pump exists
During work, because wheel backface does not have blade, therefore whipping sand water is unable to.Now higher-pressure region can be from the edge arrival center of pump case
The power transmission shaft in area.Such structure can cause sand water to be gone out from the gap between axle housing, and working environment can be made a big impact,
The safety of normal production is hindered, present solution is plate washer of burn-oning on the power transmission shaft of motor.And due to the sand water gone out
There is extremely strong erosive wear ability under high pressure, high pressure sand water can cause the gap between axle housing increasing, and baffle plate grinds
Damage also quickly, Jing often wants repair welding, such as repair welding not in time, the sand water gone out can at once damage motor.
The content of the invention
The purpose of the present invention is：A kind of method and structure for reducing the abrasion of sand-blasting machine sand pump is provided, it can be prevented effectively from sand
Water overflows the damage caused to motor, and need not arrange baffle plate, improves the whole service life and production efficiency of sand pump, with
Overcome the deficiencies in the prior art.
What the present invention was realized in：The method for reducing the abrasion of sand-blasting machine sand pump, on the impeller of sand pump through hole is opened up, and is made
The sand water inlet region of sand pump enters the regional connectivity of sand pump housing by the through hole of setting on impeller and power transmission shaft, makes sand pump
Sand water inlet region and power transmission shaft are collectively forming low-pressure area into the region of sand pump housing, make impeller and the outside of blade form height
Nip, when power transmission shaft impeller, blade are rotated, makes the gap location between sand water inlet and power transmission shaft and sand pump housing equal
Negative pressure is formed, so as to avoid gap of the sand water between power transmission shaft and sand pump housing from spraying, so as to greatly reduce the mill of sand-blasting machine
Damage.
The improved structure of sand pump, including sand pump housing, power transmission shaft, impeller, the bottom of sand pump housing bottom is sand water inlet,
Sand water out is provided with the side of sand pump housing, power transmission shaft import is provided with the top of sand pump housing, transmission the tip of the axis passes through
Power transmission shaft import is entered in sand pump housing；The pinboard being connected with transmission the tip of the axis is provided with sand pump housing, at pinboard
In impeller top, and the bottom of pinboard is connected by connecting pole with the top of impeller, connecting pole along pinboard Central Symmetry,
Gap is arranged, and the bottom of impeller is connected with blade, through hole is provided with the middle part of impeller；The center of power transmission shaft, pinboard and impeller
It is coaxial.
As a result of above-mentioned technical proposal, compared with prior art, the present invention have adjusted the impeller mechanism of sand-blasting machine, make
Low-pressure area is conducted to wheel backface central area, because the gap of power transmission shaft and sand pump arenaceous shell body is in low-pressure area, therefore
In the course of work, the gap between axle housing is negative pressure suction condition, without spraying sand water, be therefore, there is no need on power transmission shaft
Welding plate washer, will not also damage motor, not only improve working environment, and significantly improve the whole service life of sand pump,
So as to significantly improve operating efficiency and product quality.Present configuration is simple, with low cost, and using effect is preferable.
Description of the drawings
Accompanying drawing 1 is structural representation of the invention；
Accompanying drawing 2 is the fundamental diagram of prior art.
Specific embodiment
Embodiments of the invention：The method for reducing sand-blasting machine abrasion, on the impeller of sand pump through hole is opened up, and makes the sand of sand pump
Water inlet region enters the regional connectivity of sand pump housing by the through hole of setting on impeller and power transmission shaft, makes the sand water inlet of sand pump
Region and power transmission shaft are collectively forming low-pressure area A into the region of sand pump housing, and the outside for making impeller and blade forms higher-pressure region B,
When power transmission shaft impeller, blade are rotated, it is respectively formed the gap location between sand water inlet and power transmission shaft and sand pump housing negative
Pressure, so as to avoid gap of the sand water between power transmission shaft and sand pump housing from spraying, so as to reduce the abrasion of sand-blasting machine.
The improved structure of sand pump, including sand pump housing 1, power transmission shaft 2, impeller 3, the bottom of the bottom of sand pump housing 1 is sand water
Import 7, in the side of sand pump housing 1 sand water out 8 is provided with, and at the top of sand pump housing 1 power transmission shaft import 9, power transmission shaft 2 are provided with
End by power transmission shaft import 9 enter sand pump housing 1 in；Be provided with the sand pump housing 1 be connected with the end of power transmission shaft 2 turn
Fishplate bar 4, pinboard 4 is connected by connecting pole 5 in the top of impeller 3, and the bottom of pinboard 4 with the top of impeller 3, connecting pole
5 Central Symmetry, the gap settings along pinboard 4, the bottom of impeller 3 is connected with blade 10, at the middle part of impeller 3 through hole 6 is provided with；
The center of power transmission shaft 2, pinboard 4 and impeller 3 is coaxial.
Jing inventor is actually detected, is first without the need for baffle plate being arranged outside axle housing, also not being had using the structure of the present embodiment
There is sand water to spray, and, sand pump is greatly improved without repairing service life, relative to the sand-blasting machine of traditional structure, during without repairing
Between extend more than 5 times (traditional sand-blasting machine is repaired once for average 1-2 month, and the sand-blasting machine more than 90% after improving without repairing extremely
Service life terminates).
