[0022] Please refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a water treatment metering pump;

[0023] It includes a pump body 1 and a filtration component. A pump cover 13 is installed on the front of the pump body 1. A threaded connection port 16 is installed through the bottom of the pump cover 13. A filtration component is installed on the bottom of the pump cover 13 through the threaded connection port 16. The filtration component is used to filter the incoming liquid. The filtration component includes a filter shell 17, a connection sleeve 18, and a filter net 19. The connection sleeve 18 is installed on the top of the filter shell 17. The connection sleeve 18 is connected to the threaded connection port 16. The filter net 19 is installed inside the filter shell 17. An inlet pipe 20 is installed through the bottom of the filter shell 17. A threaded cover 21 is installed on the outer side of the bottom end of the inlet pipe 20. A disassembly cover 14 is installed on the front of the pump cover 13 through bolts. An outlet pipe 15 is installed through the top of the pump cover 13, and the top end of the outlet pipe 15 is sealed by a threaded cover 21;

[0024] The pump body 1 is driven by the motor 3. After the motor 3 is powered on, it drives the internal operation of the pump body 1, so as to generate suction in the pump cover 13 to transfer the liquid. The water treatment liquid enters the inside of the filter assembly through the inlet pipe 20. By passing the incoming liquid through the filter assembly first and then into the metering pump, the filter screen 19 installed inside the filter assembly can filter the impurities in the liquid, preventing the impurities from entering the inside of the metering pump and rubbing against the internal parts, which may cause damage to the metering pump. Since the filter housing 17 is threadedly connected to the threaded connection port 16 through the connecting sleeve 18, the filter housing 17 can be rotated and disassembled, enabling the filter assembly to be disassembled and cleaned regularly. The filtered liquid is discharged through the outlet pipe 15 at the top. The threaded cap 21 is used to seal the outlet pipe 15 and the inlet pipe 20.

[0025] Please refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a water treatment metering pump;

[0026] It includes an injection pipe 5 and an oil storage cylinder 8. A chassis 2 is installed at the bottom of the pump body 1, a motor 3 is installed at the top of the pump body 1, an oil filling port 4 is installed at the top of the pump body 1, an injection pipe 5 is installed at the top end of the oil filling port 4, a support shell 6 is installed at the top end of the injection pipe 5, a mounting shaft 7 is threadedly installed at the top of the support shell 6, an oil storage cylinder 8 is installed through the inside of the mounting shaft 7, a fuel filling port 9 is opened at the top of the oil storage cylinder 8, a sealing cover 10 is installed inside the fuel filling port 9, a transmission pipe 11 is installed through the bottom of the oil storage cylinder 8, and the transmission pipe 11 passes through the injection pipe 5 and extends into the inside of the pump body 1, and an oil outlet head 12 is installed at the bottom end of the transmission pipe 11;

[0027] The chassis 2 is used to support the pump body 1. After the motor 3 is powered on, it converts electrical energy into kinetic energy and drives the pump body 1 to transfer the liquid. The oil filling port 4 provides space for the lubricating oil to enter the inside of the pump body 1. By adding lubricating oil to the inside of the pump body 1, the lubrication effect inside the pump body 1 is better. In order to facilitate adding lubricating oil each time, a support shell 6 is installed through the injection pipe 5 at the top of the oil filling port 4. The support shell 6 provides a position for the installation of the oil storage cylinder 8. The oil storage cylinder 8 is threadedly installed on the top of the support shell 6 by using the mounting shaft 7. Lubricating oil is added to the inside of the oil storage cylinder 8 through the fuel filling port 9 and then sealed by the sealing cover 10. The oil storage cylinder 8 is made of rubber and can be extruded. By extruding the oil storage cylinder 8, the lubricating oil stored inside the oil storage cylinder 8 is transmitted to the inside of the pump body 1 through the transmission pipe 11 and finally discharged through the oil outlet head 12. The oil storage cylinder 8 can store the lubricating oil consumption for multiple times, thus facilitating adding lubricating oil to the pump body 1 each time.

[0028] Working principle: Before using the water treatment metering pump, it is necessary to check whether there are any problems affecting its use. First, install the water treatment metering pump at the required position through the chassis 2, and drive the pump body 1 to operate through the drive motor 3, so that the liquid can be transmitted through this metering pump. When transmitting the liquid, the liquid will first pass through the filtration component, and the liquid is filtered through the filtration component to prevent impurities from entering the interior of the metering pump and causing damage due to friction between the interior of the metering pump and the impurities.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.
