Description

Technical Field

[0001] This utility model relates to the field of plunger pump technology, specifically a multifunctional adjustable water output plunger pump. Background Technology

[0002] Plunger pumps, as positive displacement pumps that rely on the reciprocating motion of a plunger to achieve liquid intake and discharge, are widely used in industrial cleaning, agricultural irrigation, and engineering machinery due to their high pressure and high efficiency. Traditional plunger pumps often adopt an axial or radial symmetrical layout, with fixed positions for the inlet, outlet, and outlet channels, and a single discharge direction, resulting in poor adaptability to complex working conditions.

[0003] Existing plunger pumps mostly have a unidirectional outlet channel, which can only drain water in one direction. If it is necessary to switch the outlet direction, additional pipeline valves are required, which increases the system complexity and leakage risk. When different areas need to be irrigated alternately, traditional plunger pumps need to be shut down to replace the pipeline, which seriously affects the operation efficiency.

[0004] Therefore, a multi-functional adjustable plunger pump is needed to improve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional adjustable water output plunger pump to solve the problems mentioned in the background art.

Figure 1 , 23, 4, 5, and 6, a multi-functional adjustable water output plunger pump, including a pump body 1, with fixed feet 3 fixedly connected to both sides of the lower end of the pump body 1. The lower end of the pump body 1 is connected to the mounting surface through the fixed feet 3 to ensure stability during operation; the bolted connection between the plunger chamber 5 and the end cover 11, and the precise fit between the plunger 17 and the chamber cavity, further enhance the overall structural rigidity and reduce vibration and noise. The plunger chamber 5 is provided at the front end of the pump body 1, and the water outlet 6 is provided perpendicularly to the upper end of the plunger chamber 5. The rear end of the water outlet 6 is provided with several... The main outlet pipe 13 is equipped with a valve 15 and a sealing element on the outside of each outlet pipe 13. When the outlet pipe 13 is connected to an external pipe, the sealing element is tightly fitted to the connection between the outlet pipe 13 and the external pipe. The plunger chamber 5 is equipped with a docking end 10, and the two sides of the docking end 10 are connected with end caps 11 by bolts. The lower end of the end cap 11 is equipped with a water inlet end 12. The docking end face of the end cap 11 is provided with an installation groove 21, and a filter element is provided inside the installation groove 21.

[0021] The upper end of the plunger chamber 5 is vertically equipped with a water outlet 6, and the rear end is connected to several water outlet pipes 13. Each water outlet pipe 13 is independently equipped with a valve 15. By controlling the opening and closing of the valve 15 individually, single or multiple water outlets can be switched without stopping the machine to replace the pipeline. In agricultural irrigation, water can be supplied to different areas alternately by opening different valves 15, thereby improving the efficiency of operation.

[0022] Please refer to Figure 6 The sealing element includes a sealing ring 14 fixedly connected to the outside of the water outlet pipe 13, and one end of the sealing ring 14 is open, and the inner wall of the sealing ring 14 is provided with a soft bladder 25, and the outer side of the sealing ring 14 is provided with an annular groove 4.

[0023] A sealing element is provided on the outside of the water outlet pipe 13, consisting of a sealing ring 14, a soft bladder 25, and an annular groove 4. The sealing ring 14 adopts an open structure. When the external pipe is inserted into the water outlet pipe 13, the sealing ring 14 is squeezed and deformed. The soft bladder 25 on the inner wall fills the gap, and the annular groove 4 on the outer side forms a negative pressure sealing cavity, providing double protection against leakage at the connection. Compared with traditional flat seals, this design is suitable for pipes of different diameters. As the usage time increases, the soft bladder 25 can compensate for the wear of the sealing ring 14 and extend the sealing life.

[0024] Please refer to Figure 4 and 5 The filter element includes a frame 23 disposed inside the mounting groove 21, and an opening 22 is provided at the lower end of the frame 23. A filter screen 24 is disposed inside the frame 23. The filter screen 24 is disposed at an angle inside the frame 23, and the filter screen 24 is arc-shaped.

[0025] The end cap 11 is fixed to the mating end 10 of the plunger chamber 5 by bolts. The lower end of the end cap 11 is provided with a water inlet 12. The mating end face is provided with an installation groove 21 and a filter element is built in. The lower opening 22 of the frame 23 is connected to the water inlet 12. After the liquid enters through the opening 22, it is filtered by the inclined arc-shaped filter screen 24 to remove impurities. The inclined arc design can increase the filtration area and reduce clogging. Impurities settle to the bottom of the opening 22 due to gravity, which is easy to clean. The frame 23 and the installation groove 21 are detachably connected to facilitate the replacement of the filter screen 24.

[0026] The plunger chamber 5 has several independent chambers inside, each chamber is equipped with a plunger 17, and a spring 18 is installed on the outside of the plunger 17. The pump body 1 has an inner cavity 19 inside, and a shaft 2 is installed through the middle of the inner cavity 19. Several cams 20 corresponding to the positions of the plunger 17 are installed at equal intervals on the shaft 2. An air chamber 7 and a pressure gauge 16 are respectively installed at the upper end of the water outlet 6. A return water seat 9 is installed on one side of the upper end of the water outlet 6, and a pressure regulating valve 8 is installed on the upper end of the return water seat 9.

[0027] An internal cavity 19 is formed inside the pump body 1, through which a shaft 2 is installed. Several cams 20 are fixed at equal intervals on the shaft 2. The plunger chamber 5 is divided into independent chambers, each containing a plunger 17, with a spring 18 sleeved on the outside of the plunger 17. When the shaft 2 is driven to rotate by an external power source, the cams 20 push the plunger 17 to compress the spring 18. The plunger 17 reciprocates under the restoring force of the spring 18, completing the suction and discharge of liquid. The independent working design of the multiple plungers 17 can improve flow stability and reduce pressure fluctuations.

[0028] An air chamber 7 and a pressure gauge 16 are installed at the upper end of the water outlet 6. A return water seat 9 and a pressure regulating valve 8 are provided on one side. The air chamber 7 is filled with compressed gas, which can absorb liquid pulsation and stabilize the water outlet pressure. The pressure gauge 16 monitors the system pressure in real time. When the pressure exceeds the set value, the pressure regulating valve 8 opens, and part of the liquid flows back to the water inlet 12 through the return water seat 9 to achieve overload protection.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
