Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic diaphragm metering pumps, in particular to a hydraulic diaphragm metering pump with an inlet end resistant to high pressure. Background Art

[0002] A metering pump is a type of fluid conveying machinery. Its outstanding feature is that it can maintain a constant flow rate that is independent of the discharge pressure. A metering pump can simultaneously complete the functions of conveying, metering, and regulation, thereby simplifying the production process. By using multiple metering pumps, several media can be input into the process flow in an accurate proportion for mixing. Due to its own prominence, metering pumps are now widely used in various industrial fields such as petrochemicals, pharmaceuticals, and food. A metering pump generally includes a worm gear drive mechanism, an eccentric rotary mechanism, a plunger reciprocating mechanism, and a diaphragm pump head mechanism. The eccentric rotary mechanism is driven by the worm gear drive mechanism, and the eccentric wheel of the eccentric rotary mechanism is driven by the eccentric wheel. The plunger in the dynamic plunger reciprocating mechanism performs reciprocating motion, and the plunger drives the diaphragm of the diaphragm pump head mechanism to deform. The deformation of the diaphragm will change the volume of the pump chamber, thereby achieving the purpose of conveying the medium. Although the currently used hydraulic diaphragm metering pump can meet the use requirements, it still has certain defects in actual use. For example, the currently used hydraulic diaphragm metering pump is not convenient for cleaning the dust cover. The surface of the dust cover is easy to absorb dust after long-term use, which is easy to cause the dust cover to be blocked over time, affecting the heat dissipation effect of the hydraulic diaphragm metering pump. Improvement is needed. Therefore, a hydraulic diaphragm metering pump with high pressure resistance at the inlet end is now proposed. Utility Model Content

[0035] In the present embodiment: by providing a protective cover 2 and a dustproof net 4, the top of the metering pump body 1 can be protected, and heat dissipation is also convenient.

When the metering pump body 1 is running, the control switch of the rotating motor 501 is started, and the rotating motor 501 drives the rotating shaft 502 to rotate, and the rotating shaft 502 drives the fan blades 503 to rotate, and the heat inside the metering pump body 1 is blown out through the fan blades 503 to dissipate heat inside the metering pump body 1. At the same time, the rotating shaft 502 drives the brush plate 504 to rotate, and the surface of the dustproof net 4 of the brush plate 504 is cleaned to separate the dust from the dustproof net 4, and then the dust is blown away by the action of the fan blades 503, so that the dustproof net 4 can be cleaned, and the clogging of the dustproof net 4 is avoided to improve the heat dissipation effect.
