Description
Technical Field
The utility model belongs to the chemical industry technique, concretely relates to double air chamber diaphragm formula pulse damper.
Background
The conveying of high-density media is currently carried out by a screw pump in China. The screw pump is sealed by filling, leakage exists in the operation process, and once the high-density medium leaks, the high-density medium pollutes air in a production field and poisons bodies of workers on the field due to high specific gravity, high permeability, pollution and toxicity.
The pulse type damper is generally arranged on a pump body of a delivery pump, and has the functions of buffering pulses of high-density media output by the pump, reducing the influence of the pulses on a system, stabilizing the pressure and the flow of fluid, eliminating the vibration of a pipeline, protecting downstream instruments and equipment, increasing the volumetric efficiency of the pump and the like.
The damper in the prior art generally utilizes a solid medium to directly intercept fluid so as to achieve the effect of buffering pressure pulsation or flow pulsation, and the pulsation damper is suitable for high-frequency pulsation application and is not suitable for the requirement of high-density medium conveying.
Disclosure of Invention
The utility model aims at providing a two air chamber diaphragm formula pulse damper, it can satisfy the medium buffering requirement of high density medium delivery pump.
The technical scheme of the utility model as follows:
a diaphragm type pulse damper with double air chambers comprises a cylinder body and end enclosures fixedly connected with the upper end and the lower end of the cylinder body in a sealing mode, wherein diaphragms are arranged at two inner end portions of the cylinder body respectively, the diaphragms and the end enclosures to form air chambers, and a medium cavity is enclosed between the diaphragms at two ends and the cylinder body.
The seal head is fixedly connected with the two ends of the cylinder body through flange structures, a gap is reserved between the mounting flange of the seal head and the mounting flange of the cylinder body, and the edge part of the diaphragm is mounted in the gap.
And an inflator pump is arranged on the seal head.
The inflator pump is connected with an argon pipeline and used for pre-filling argon into the air chamber.
And a pressure gauge is arranged between the inflator pump and the seal head.
The side wall of the cylinder body is provided with a connecting pipe.
The connecting pipe is connected with the delivery pump.
The utility model discloses an effect as follows: the diaphragms made of soft materials are designed at the two ends of the cylinder body, so that air chambers are formed at the two sides of the cylinder body respectively, a double-air-chamber structure is further formed, the space size of the medium cavity in the cylinder body is changed by utilizing the deformation of the diaphragms, and the damper is suitable for the medium buffering requirement of a high-density medium delivery pump.

Detailed Description
The present invention will be further explained with reference to the drawings and the detailed description.
As shown in figure 1, the double-air-chamber diaphragm type pulse damper comprises a cylinder body 2 and a seal head 4 which is respectively and fixedly connected with the upper end and the lower end of the cylinder body 2 in a sealing way, wherein an inflator pump 5 and a pressure gauge 6 are arranged on the seal head 4. The side wall of the cylinder body 2 is provided with a connecting pipe 1.
And a diaphragm 3 installed at both ends in the cylinder 2.
The diaphragm 3 is made of soft material and has a certain thickness, and PTFE is selected as the material of the diaphragm 3.
When the air is not inflated, the diaphragm 3 is depressed toward the inside of the cylinder 2 to form a spherical surface.
The seal head 4 is fixedly connected with the two ends of the cylinder body 2 through flange structures, a gap is reserved between the mounting flange of the seal head 4 and the mounting flange of the cylinder body 2, and the edge part of the diaphragm 3 is mounted in the gap, so that the flange structures of the two parts compress the diaphragm 3, and the diaphragm 3 is fixed.
The inflator 5 precharges the space outside the diaphragm 3 with argon gas.
The space enclosed by the outer part of the diaphragm 3 and the end enclosure 4 is called an air chamber, and the space enclosed by the diaphragm 3 at two ends and the cylinder 2 is called a medium cavity. Due to the adoption of the double diaphragms at the two ends of the cylinder body 2, the two ends of the cylinder body 2 are respectively provided with the air chambers filled with argon, so that the double-air-chamber structure can well perform pulse buffering on the conveyed high-density medium.
The main technical indexes of the double-air-chamber diaphragm type pulse damper are shown in the following table 1
Parameter meter for double-air-chamber diaphragm type pulse damper
The connecting pipe 1 arranged on the cylinder body 2 can be connected with a delivery pump, receives the high-density medium transmitted by the delivery pump, buffers the pulse of the high-density medium output by the pump, and reduces the influence of the pulse on the system.
