Abstract
The utility model relates to a pneumatic reciprocal liquid filling pump. Between an air distribution portion and a pneumatic portion, two air passages are communicated with an air cylinder body in an air distribution plate, and two air passages are respectively communicated with an upper cavity of the air cylinder and a lower cavity of the air cylinder. A common piston rod is adopted between the air cylinder and a liquid cylinder, one end of the common piston rod is connected with an air cylinder piston in the air cylinder, and the other end is connected with a liquid cylinder piston in the liquid cylinder. The pneumatic reciprocal liquid filling pump of the utility model has the advantages of simple structure, size reduction, convenient manufacture, energy saving, convenient operation, favorable technical performance and favorable social and economic benefit.
Description
The utility model belongs to the pneumatic reciprocal topping-up pump that is mainly used in petroleum chemical industry in the what mechanical pump kind equipment field.
Before the utility model, in the topping-up pump that petroleum chemical industry uses, the prior art the most approaching with the utility model is the POMP pump that Tokyo I.E.C. Co., Ltd. produces.Its distribution partial structure complexity, cylinder block and liquid cylinder adopt separation structure, and be bulky, process, debug, maintenance difficult, manufacture cost height, waste energy again.
In order to overcome above-mentioned shortcoming, the purpose of this utility model is: simplified structure, reduced volume, the saving energy, be easy to process, debug, reduce manufacture cost, be convenient to Operation and maintenance.
Detailed content of the present utility model is made up of distribution part (1,2,3,4,5,6,7,8,9), pneumatic part (10,11,12,13,14,15) and fluid injection part (13,16,17,18,19,20,21,22) as shown in Figure 1.
Distribution partly is made up of pneumatic pannel 1, cavity of resorption air vent 2, inlet hole 3, epicoele air vent 4, air chamber 5, distributing valve 6, top board 7, positioning plate 8, positioning means 9.
Pneumatic part 15 is formed at the bottom of by cylinder block 10, upper chamber of air cylinder 11, cylinder piston 12, piston rod 13, lower chamber of air cylinder 14, cylinder.
Fluid injection partly by at the bottom of piston rod 13, liquid discharging valve 16, fluid cylinder top 17, liquid cylinder 18, liquid cylinder piston 19, fluid cylinder chamber 20, the fluid cylinder 21, feed liquor valve 22 forms.
An inlet hole 3 is arranged on the pneumatic pannel 1, two air vents 2 and 4 that interlink with cylinder block 10 are arranged in the pneumatic pannel 1, top board 7 is connected with pneumatic pannel 1 and positioning plate 8 usefulness screws, the positioning means 9 that limits distributing valve 6 mobile positions is housed on the positioning plate 8, form air chamber 5 between distributing valve 6 and the pneumatic pannel 1, and slipper seal, distributing valve 6 moves up and down air chamber 5 is connected with inlet hole 3 and cavity of resorption air vent 2 or inlet hole 3 and epicoele passage 4 respectively, and pneumatic pannel 1 and positioning plate 8 usefulness screws and cylinder block 10 are connected.
There is the air vent 2 and 4 in two air vents and the pneumatic pannel 1 to be connected in the cylinder block 10, epicoele air vent 4 and upper chamber of air cylinder 11 communicate, cavity of resorption air vent 2 and lower chamber of air cylinder 14 communicate, adopt public piston rod 13 between cylinder chamber and the fluid cylinder chamber, one end of piston rod 13 is connected with cylinder piston 12 in lower chamber of air cylinder 14, the other end is connected with liquid cylinder piston 19 in fluid cylinder chamber 20, and cylinder block 10 is connected with 15 usefulness screws at the bottom of the cylinder.
At the bottom of the cylinder 15, at the bottom of the fluid cylinder top 17, liquid cylinder 18, fluid cylinder 21, all be connected between them with screw, liquid discharging valve 16 and fluid cylinder push up 17 and feed liquor valve 22 with 21 all use and be threaded at the bottom of the fluid cylinder.
Working principle of the present utility model is: the pressurized air that enters air chamber 5 by inlet hole 3, enter lower chamber of air cylinder 14 through cavity of resorption air vent 2, cylinder piston 12 is moved upward, driving distributing valve 6 moves upward, air chamber 5 is communicated with inlet hole 3 and epicoele air vent 4, at this moment pressurized air enters in the upper chamber of air cylinder 11 through epicoele air vent 4, cylinder piston 12 is moved downward, driving distributing valve 6 again moves downward, make air chamber 5 get back to original position, communicate with inlet hole 3 and epicoele air vent 4 again, because piston rod 13 constitutes one with cylinder piston 12 and liquid cylinder piston 19, the to-and-fro motion of cylinder piston 12, it is reciprocating to drive liquid cylinder piston 19 by piston rod 13, thus the discharge that has realized passing through the suction of 22 pairs of liquid of feed liquor valve and passed through 16 pairs of liquid of liquid discharging valve.
Good effect of the present utility model: simple in structure, volume is little, power consumption is little, saved the energy, save raw material, be convenient to manufacturing, reduced cost of production, be convenient to operation, improved working efficiency.
Description of drawings: Fig. 1 is structural representation of the present utility model and Figure of abstract.
Most preferred embodiment: at the bottom of piston rod 13, liquid discharging valve 16, fluid cylinder top 17, liquid cylinder 18, liquid cylinder piston 19, the fluid cylinder 21, the material of feed liquor valve 22 adopts stainless steel 0C
r18N
i9 (T
1), the material of cylinder piston 12 adopts cast aluminium, and the material of pneumatic pannel 1 adopts 45
#Steel, and its internal surface (surface that contacts with distributing valve 6) requires the quenching grinding to surface roughness, and the material of distributing valve 6 adopts GC
r15, the surface of contact of it and positioning means 9 requires to quench, and the positioning element of positioning means 9 adopts roller construction.The area of cylinder piston 12 and liquid cylinder piston 19 is determined according to lifting rate and discharge opeing pressure size.
