Description

Technical Field

[0001] The utility model relates to the technical field of metering pumps, in particular to a large-flow hydraulic diaphragm metering pump. Background Art

[0002] Metering pump is a kind of fluid conveying machinery, and its outstanding feature is that it can maintain a constant flow rate regardless of the discharge pressure. Metering pumps can simultaneously complete the functions of conveying, metering and regulating, thereby simplifying the production process. Using multiple metering pumps, several media can be input into the process flow in accurate proportions for mixing. Due to its own outstanding features, metering pumps have now been widely used in various industrial fields such as petrochemicals, pharmaceuticals, and food.

[0003] When a traditional metering pump is used for high-flow delivery, the medium passing through the metering pump is prone to vibration due to the large flow rate. Since the metering pump is connected to the mounting platform by bolts, long-term vibration can easily cause the metering pump and the mounting platform to loosen, which can easily cause damage to the metering pump. To this end, we propose a large-flow hydraulic diaphragm metering pump. Utility Model Content

Since a plurality of groups of symmetrical threaded rods are welded at the shell wall of the metering pump body, after the plurality of groups of threaded rods are respectively passed through the rubber pad A and the T-plate, the threaded rods are threadedly connected with the locking threaded sleeve, so that the locking threaded sleeve squeezes the T-plate, and the anti-loosening bolt is threadedly connected with the threaded rod, so that the anti-loosening bolt limits the locking threaded sleeve, thereby avoiding vibration of the metering pump body when conveying the medium, causing the installation stability of the metering pump body, and then the external bolts are respectively passed through the through holes at the base plate and the rubber pad B to connect with the outside, so as to realize the installation support of the metering pump body.

[0007] Specifically, it also includes a detection mechanism, and the detection mechanism is installed on the shell wall of the metering pump body.

[0008] By adopting the above technical solution, the delivery flow rate of the metering pump body can be detected by the detection mechanism.

[0009] Specifically, the detection mechanism is composed of a discharge pipe, a flow detection sensor, a processor and a buzzer. The discharge port of the metering pump is connected to a discharge pipe, a flow detection sensor is installed on the wall of the discharge pipe, a processor is installed on the shell wall of the metering pump body, and a buzzer is installed on the shell wall of the metering pump body.

[0010] By adopting the above technical solution, when the metering pump body is subjected to flow warning detection, since a detection mechanism is installed on the shell wall of the metering pump body, and the detection mechanism is composed of a discharge pipe, a flow detection sensor, a processor and a buzzer, when the medium enters the discharge pipe, since a flow detection sensor is installed on the wall of the discharge pipe, when the flow of the metering pump body is opened to the maximum, the flow detection sensor detects that the flow of the conveying medium has not been reached, and the flow detection sensor transmits a signal to the processor, so that the processor controls the buzzer, and the buzzer rings, thereby preventing the metering pump from being blocked and affecting the medium conveying flow.

[0011] Specifically, the liquid inlet port of the metering pump body is connected to a liquid inlet pipe.

[0012] By adopting the above technical solution, the external medium can conveniently enter the metering pump body through the liquid inlet pipe.

[0013] Specifically, the plate wall of the bottom plate and the outer wall of the rubber pad B are both provided with through holes.
