Abstract
The utility model relates to a pneumatic reciprocating pump, which comprises an air cylinder, a water pump, a push rod and a water pump plunger; the push rod is arranged on the air cylinder; the water pump plunger is arranged on the water pump; the push rod is connected with the water pump plunger; and a V-shaped seal ring for sealing is arranged between the water pump plunger and the inner wall of the water pump. Needing only one standard air cylinder, the pneumatic reciprocating pump can increase or decrease the working pressure by means of water pump cylinders with different surface areas, so that the service efficiency can be increased; and meanwhile, the cost is reduced.
Description
Technical field
The utility model relates to a kind of pneumatic reciprocating pump, and particularly a kind of utilization efficiency height, the pneumatic reciprocating pump that cost is low belong to the fluid device technical field.
Background technique
In the fluid device, membrane pump with pneumatic drive is a common equipment, and its actual working pressure is not because the loss in the operation reaches ideal value.And cost price is higher.
The model utility content
The utility model purpose is to have proposed a kind of utilization efficiency height, pneumatic reciprocating pump that cost is low in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pneumatic reciprocating pump comprises cylinder, water pump, push rod, pump plunger; Described push rod is arranged on the cylinder; Described pump plunger is provided with on the water pump; Described push rod links to each other with pump plunger.
Preferably, be provided with V-shaped seal ring between described pump plunger and the water pump inwall, in order to sealing.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Pneumatic reciprocating pump of the present utility model only needs a standard cylinder, and water pump cylinder body increase that just can be by the different table area or dwindle operating pressure can improve utilization efficiency; Reduce cost simultaneously.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Fig. 1 is the first user mode schematic representation of pneumatic reciprocating pump of the present utility model;
Fig. 2 is the second user mode schematic representation of pneumatic reciprocating pump of the present utility model;
Wherein: 1, cylinder; 2, water pump; 3, push rod; 4, pump plunger; 5, V-shaped seal ring; 6, go up one-way valve; 7, following one-way valve.
Embodiment
Below in conjunction with accompanying drawing the utility model is described.
Be depicted as a kind of pneumatic reciprocating pump described in the utility model as accompanying drawing 1,2, comprise cylinder 1, water pump 2, push rod 3, pump plunger 4; Described push rod 3 is arranged on the cylinder 1; Described pump plunger 4 is provided with on the water pump 2; Described push rod 3 links to each other with pump plunger 4; Be provided with V-shaped seal ring 5 between described pump plunger 4 and water pump 2 inwalls, in order to sealing; The outlet port of described water pump is provided with one-way valve 6 and following one-way valve 7, is used as the outflow outlet of water, so that the controlled water flow direction.
Assembling one material is the water pump 2 of stainless steel or plain carbon steel on cylinder 1, and the water pump internal surface requires to be bright and clean minute surface, and with the sealing of guaranteeing that it moves back and forth under cylinder promotes, its closing property of sealing is also guaranteed by V-shaped seal ring.Pressurized air is passed to water pump by the pressure that the cylinder sectional area produces by the plunger that is connected with push rod, produces than original greater or lesser pressure.Obtain bigger pressure as need, then the water pump sectional area just is less than the cylinder sectional area; Obtain less pressure as need, the sectional area that connects water pump just is greater than the sectional area of cylinder.
Pressurized air pressure is generally P1, and cylinder bore is d1, and the water pump diameter is d2, and the pressure that final water pump produces is P2, then is formulated as: P1 π (d1/2)
2=P2 π (d2/2)
2, be P2=P1d 1
2/ d2
2
Thus, the duplicate ratio by cylinder and water pump diameter is a concrete multiple when entering with regard to the pressure of knowing new generation.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
Pneumatic reciprocating pump of the present utility model only needs a standard cylinder, and water pump cylinder body increase that just can be by the different table area or dwindle operating pressure can improve utilization efficiency; Reduce cost simultaneously.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
