Description

The vertical pneumatic pump of environmental protection

Technical field

The utility model belongs to the pneumatic pump technical field, particularly relates to the vertical pneumatic pump of a kind of environmental protection.

Background technique

Pneumatic pump is widely used in oil, industries such as chemical industry, conveying has corrosivity, pH value, poisonous and harmful, inflammable and explosive liquid and food beverage industry, at present disclose a kind of pneumatic barrel pump and mainly contain pneumatic part and liquid extraction part, pneumatic part provides power, liquid supplying part mainly utilizes reciprocating pump extracting liq under the effect of pneumatic part, its working state mainly is by pressurized air input cylinder, promote two take a breath valve plate and piston motions on the piston rod, and under the power-assisted effect of cylinder inner spring, do back and forth and be synchronized with the movement, thereby finish the displacement and the discharging of the pressurized gas in the cylinder, and then the piston rod in the realization reciprocating pump drives piston on the connecting rod and does and pump, and finishes the input and output of liquid by the one-way valve that is installed in the reciprocating pump lower end.Enter displacement and the discharging smoothly that the pressurized gas in the cylinder goes round and begins again for making, existing pneumatic pump mainly adopts and will connect by the support mode in the middle of above-mentioned two parts, make like this and have bigger space between two parts, and in sealing configuration, be provided with threaded pressure ring, utilize screw thread rotation to regulate the interior seal ring of sealing seat, some is exposed to piston rod in the atmosphere.Piston rod adopts the hollow type structure, for being discharged, pressurized gas on the piston rod of hollow type, radially is processed with air outlet hole, when piston rod movement during to the space between cylinder and the reciprocating pump, pressurized air is discharged by air outlet hole, so far forms the circulation of pressurized gas like this.The pneumatic pump of said structure and exhaust mode show following defective and deficiency when reality is used:

1, since pressurized air from the joint space drainage between cylinder and the reciprocating pump, erasure effect is undesirable, noise is big, simultaneously when pneumatic pump is worked, has bigger vibration.
