Abstract
The utility model provides an efficient anti-corrosion liquid-absorbing pump, which comprises a pump body, wherein a gland 9 is arranged at the upper end of the pump body 1; the gland 9 is used for fixing a connection rod positioning block 3; the connecting rod positioning block 3 is provided with a breathing hole 13; the lower end of the pump body 1 is connected with a liquid inlet tube flange 10, and the joint is sealed by a silicon rubber sealing gasket 12; a lower valve 4 is arranged in a middle hole of the liquid inlet tube flange 10; a lower-valve limiting bracket 5 is arranged at the upper end of the lower valve 4; the upper and lower parts of the entire pump body are connected via a lead screw 8. In the liquid-absorbing pump, a porous embedded valve is adopted. After the adoption of the porous valve, liquid flows inwards and is drained from a plurality of holes, and the flow of the liquid is increased, so that the conveying speed of the liquid is increased. Meanwhile, the embedded valve is prevented from being moved randomly under the condition of increase of the liquid flow, so that the problem of valve stability under the condition of large flow is solved.
Description
Technical field
The utility model belongs to mechanical field, is specifically related to a kind of reciprocating pump of carrying for highly corrosive, high foam, high concentration liquid specially.
Background technique
Filling liquid requirement flow is large, speed is fast, precision is high, and existing liquid delivery pump mainly exists 2 problems:
1. valve is young, and when liquid sucks and discharges, flow is little, consuming time; If valve is strengthened, easily produces valve stability problem.
2. piston leather hose around adopts rubber, is not suitable for the liquid of carrying corrosivity strong.
Summary of the invention
The purpose of this utility model will overcome deficiency of the prior art exactly, and back and forth mouthful suction pumps of a kind of positive displacement of carrying for highly corrosive, high foam, high concentration liquid is specially provided.
The technical solution of the utility model is:
A kind of efficient corrosion resisting suction pumps is provided, comprises the pump housing, it is characterized in that: the pump housing 1 upper end is provided with gland 9, and gland 9 is fixed connecting rod positioning block 3, connecting rod positioning block 3 is provided with a spiracle 13; The lower end of the described pump housing 1 is connected with liquid inlet pipe flange 10, joint is sealed by silicone rubber seal gasket 12, on liquid inlet pipe flange 10 intermediate holes, lower valve 4 is housed, lower valve limiting bracket 5 is equipped with in the upper end of lower valve 4, piston 7 is equipped with in the inside of the described pump housing 1, and the middle and upper part of piston 7 combines with piston rod 2; Piston 7 forms by upper and lower two, and leather cup 11 is equipped with in the junction of two, and the inside of piston 7 is hollow, and lower narrow wide, valve 6 is equipped with in centre, and the whole pump housing is connected by lead screw 8 up and down.
The utility model has the advantage of:
1. this suction pumps adopts porous embedded valve.Porous valve makes liquid flow into and discharge from a plurality of holes, has increased the flow of liquid, thereby has strengthened the transporting velocity of liquid.Meanwhile, embedded valve can at will not move valve in the situation that fluid flow strengthens, and has solved the valve stability problem under heavy traffic condition.
2. this suction pumps adopts polyethylene as the material of piston, and the existing strong alkali-acid resistance corrosive action of this material has again stretching and pliability of rubber, is applicable to conveying corrosive liquid, and long-time use is not easy to wear yet, and the precision of liquid extraction is very high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to accompanying drawing; attached the utility model efficient corrosion resisting suction pumps that Figure 1 shows that; the pump housing 1 upper end is provided with gland 9; its effect is to fix connecting rod positioning block 3, has a spiracle 13 on connecting rod positioning block 3, and the lower end of the pump housing 1 is connected with liquid inlet pipe flange 10; joint is sealed by silicone rubber seal gasket 12; on liquid inlet pipe flange 10 intermediate holes, lower valve 4 is housed, lower valve limiting bracket 5 is equipped with in the upper end of lower valve 4, is used for the height that limiter valve opens; Piston 7 is equipped with in the inside of the pump housing 1, and the middle and upper part of piston 7 combines with piston rod 2; Piston 7 forms by upper and lower two, and leather cup 11 is equipped with in the junction of two, and leather cup 11 has strengthened the sealing of piston 7 with the pump housing 11, and the inside of piston 7 is hollow, and lower narrow wide, be equipped with centre
Valve 6, the whole pump housing only connects by lead screw 8 up and down.
Working principle of the present utility model is:
When piston 7 and piston rod 2 upwards move, upper valve 6 is closed, lower valve 4 is opened, and liquid enters the pump housing 1 from liquid inlet pipe 10, when piston 7 moves downwards with piston rod 2, lower valve 4 is closed, upper valve 6 is opened, and the liquid that the pump housing is 1 li flows out by piston rod 2 drain pipes, and so forth motion, liquid is entered by liquid inlet pipe 10, from the drain pipe of piston rod 2, continuously outflows.
Lower valve 4 and upper valve 6 structures are just the same, are embedded in neatly in the hole of the pump housing 1 and piston 7 bottoms, have avoided piston 7 when fluid flow is large, because hydraulic shock moves left and right; On valve, drill through a plurality of holes, strengthened fluid flow, increased liquid transporting velocity, piston 7 adopts polythene materials, and corrosion that can strong alkali-acid resistance has again the pliability of rubber material.
