Technical Field

[0001] The present application belongs to the technical field of pump equipment, and specifically relates to a pump head assembly suitable for conveying a variety of fluids and a method of using the same. Background Art

[0002] A pump is a machine that conveys fluid or pressurizes fluid. It transfers the mechanical energy of the motor or other external energy to the liquid to increase the energy of the fluid. Pumps are mainly used to convey liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also convey liquid-gas mixtures and liquids containing suspended solids.

[0003] In the existing production and processing process, it is often necessary to use a pump to transport different liquids into the same container. For example, in the field of food production and processing, traditional pumps usually only transport one fluid and cannot meet the needs of transporting multiple fluids. They need to be increased in number, but this is not only costly, but also complex in structure and very inconvenient to install. In addition, although some existing pump heads can connect multiple groups of pipelines at the same time to realize the transport of multiple fluids, they lack a structure to detect flow and pressure, which easily increases the load on the pump and is more likely to cause pump failure. In view of this, a pump head assembly suitable for the transport of multiple fluids is needed to solve the above problems. Summary of the invention

[0004] The present application provides a pump head assembly suitable for conveying a variety of fluids and a method of using the same, which effectively solves the problem that existing pumps are unable to convey a variety of fluids.

[0030] Example 1

[0031] like Figure 1-6 As shown, the present application provides a pump head assembly suitable for conveying various fluids, including a base 1, a shell 2 is installed on one side of the top of the base 1, a plurality of joints 3 are arranged equidistantly on the top of the shell 2, and a pressure detection assembly for detecting fluid pressure is installed inside the shell 2. By setting the shell 2, the pressure detection assembly can be effectively protected.

[0032] The pressure detection component includes a liquid storage cylinder 4 fixedly arranged on the inner side of the shell 2. The bottom of each joint 3 extends to the inside of the shell 2 and is connected to the inside of the liquid storage cylinder 4. A valve 5 is installed on the outside of each joint 3. The valve 5 is preferably a solenoid valve for easy control. The number of joints 3 can be set according to production needs. This example is illustrated with four groups. The four groups of joints 3 can be connected to four groups of pipes respectively. These four groups of pipes are connected to different fluid sources respectively, and different types of fluids can be transported into the inside of the joints 3, thereby achieving the purpose of transporting multiple fluids at the same time. In addition, by setting the valve 5, the flow state of any joint 3 can be controlled by opening and closing the valve 5 and the opening degree.

[0033] In order to facilitate the fixed arrangement of the liquid storage cylinder 4 on the inner side of the housing 2, a fixing ring 6 is sleeved on the outside of the liquid storage cylinder 4, and a plurality of connecting blocks 7 are evenly installed around the fixing ring 6, and the other side of each connecting block 7 is connected to the inner wall of the housing 2. By setting the fixing ring 6 and the connecting block 7, the liquid storage cylinder 4 can be reinforced, and the four groups of pipes convey different fluids into the liquid storage cylinder 4. The fixing ring 6 and the connecting block 7 can reinforce the liquid storage cylinder 4 and reduce looseness caused by fluid impact.

[0034] In order to detect the fluid pressure inside the liquid storage cylinder 4, the pressure detection assembly also includes a pressure detector 8 installed outside the housing 2. The detection end of the pressure detector 8 penetrates the housing 2 and extends to the top of the inner cavity of the liquid storage cylinder 4. As the fluid enters the liquid storage cylinder 4, the pressure inside the liquid storage cylinder 4 begins to change. The pressure detector 8 can detect the pressure inside the liquid storage cylinder 4. When the pressure is abnormal, it can be convenient for workers to detect it in time to prevent fluid leakage and pipeline congestion.

[0035] In this embodiment, a connecting component for connecting to the extraction end of the pump is installed on the other side of the top of the base 1, and the other end of the connecting component extends into the interior of the outer shell 2 and is connected to the pressure detection component; a flow detection component for detecting the fluid flow is installed on the connecting component.

[0036] In this embodiment, the connection assembly includes a first connection tube 9, one end of which extends into the interior of the housing 2 and is connected to the bottom of the liquid storage cylinder 4, and the other end is connected to a detection tube 10, and the end of the detection tube 10 away from the first connection tube 9 is connected to a second connection tube 11, and the end of the second connection tube 11 away from the detection tube 10 is installed with a flange 12. The extraction end of the pump can be connected to the pump head assembly through the flange 12. After the pump is started, the pump generates suction to transport the fluid in the liquid storage cylinder 4 to a designated container or area, thereby achieving the purpose of multi-fluid transportation.

[0037] In this embodiment, the flow detection assembly includes a flow detector 13 installed on the outside of the detection tube 10, and the detection end of the flow detector 13 extends to the inside of the detection tube 10. A protective shell 14 is provided on the outside of the detection tube 10, and the bottom of the protective shell 14 is connected to the top of the base 1. The flow detector 13 is located inside the protective shell 14, and an observation window is provided on the front of the protective shell 14. A controller 15 is installed inside the protective shell 14, and an alarm device 18 is connected to the controller 15 through a line. The valve 5, the pressure detector 8 and the flow detector 13 are connected to the controller 15 through the line respectively. By setting the protective shell 14, the flow detector 13 and the controller 15 can be protected to prevent the outside world from directly contacting the flow detector 13 and the controller 15, thereby causing interference to the flow detector 13 and the controller 15. The alarm device 18 can be a warning light of different colors, a buzzer, etc., which is convenient for issuing different types of warning information so that the operator can detect it in time.

[0038] In this embodiment, the outer sleeve of the protective shell 14 is provided with a metal cage 16, a positioning rod 17 is installed at the bottom of the metal cage 16, and a positioning hole adapted to the positioning rod 17 is opened at the top of the base 1, and the bottom of the positioning rod 17 extends to the inside of the positioning hole. By providing the metal cage 16, the connection assembly and the flow detection assembly can be further isolated and protected, especially when the pump is used outdoors, it can reduce accidental collisions from the outside, ensure the stability of the connection assembly when connected, avoid loose connections caused by direct collisions, and improve safety and stability when used outdoors. In addition, the provision of the positioning rod 17 can facilitate the disassembly and assembly of the metal cage 16, thereby facilitating the inspection and maintenance of the connection assembly.

[0039] Embodiment 2:

[0040] like Figure 1-6 As shown, the method for using the pump head assembly suitable for conveying various fluids in Example 1 includes:

[0041] Connect the cover plate 12 to the extraction end of the pump 19, and connect the pump 19 to the controller 15 through the line, so that the controller 15 can control the switch of the pump 19; connect each connector 3 to various fluid sources;

[0042] Open the valve 5 corresponding to the fluid to be extracted, the fluid flows into the liquid storage cylinder 4, and turn on the pump 19 to extract;

[0043] During the fluid extraction process, the pressure detector 8 and the flow detector 13 are used to detect the fluid pressure and the fluid flow respectively. When the fluid pressure and / or the fluid flow value are abnormal, the alarm device 18 is used to sound an alarm, and the pump 19 and / or the corresponding valve 5 are closed by the controller 15. For example, when the pipeline is blocked, the fluid cannot enter the liquid storage cylinder 4 or enters in small quantities. At this time, the data detected by the flow detector 13 changes. After reaching the preset threshold, the controller 15 receives the abnormal information sent by the flow detector 13, and then the controller 15 can control the pump 19 to stop working, which can prevent the pump from idling and reduce the damage to the pump. It can also facilitate workers to intuitively understand the working status of the pump and the transportation status of the pipeline in real time, greatly improving the reliability and controllability of fluid transportation. In addition, when an abnormality occurs, the corresponding valve 5 can also be controlled to close by the controller 15, which is convenient for operators to perform maintenance.

[0044] In addition, the controller 15 can also be connected to the upper control system, which sends control instructions to the controller 15, opens the corresponding valve 5 through the controller 15 to input fluid, and opens the pump 19 through the controller 15 to extract fluid, thereby realizing automatic control of the pump head assembly.
