Description

Technical Field

[0001] This utility model relates to the field of plunger pump technology, and in particular to a plunger pump with intelligent boosting function. Background Technology

[0002] As a common type of positive displacement pump, the plunger pump changes the volume of the sealed working chamber by the reciprocating motion of the plunger in the pump cylinder, thereby realizing the intake and discharge of liquid. Due to its characteristics such as high rated pressure, compact structure, high efficiency and convenient flow regulation, it is widely used in many industrial fields such as petroleum, chemical, metallurgy, power, shipbuilding, and engineering machinery. It is especially suitable for high-pressure and low-flow working environments and is one of the key equipment for fluid transportation and pressure control in industrial production.

[0003] However, the pressure regulation of traditional plunger pumps mostly relies on manual operation. Manual adjustment depends on the operator's experience. When the system flow rate, load and other operating conditions change, it is difficult to detect pressure changes in real time and respond quickly. This may cause excessive pressure to cause equipment overload, or insufficient pressure to affect production efficiency. Therefore, this utility model proposes a plunger pump with intelligent pressure boosting function to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plunger pump with intelligent boosting function.

[0005] To achieve the above objectives, this utility model provides a plunger pump with intelligent boosting function, including a pump body. Several connecting pipes are fixedly arranged on the front of the pump body. A front plate is fixedly arranged on the front of the connecting pipes. An inlet pipe is fixedly arranged at the center of the front of the front plate. A first branch pipe is fixedly arranged through the top of the inlet pipe. A boosting regulating plate is fixedly arranged on the top of the first branch pipe. The boosting regulating plate is hollow inside. An upper pipe is fixedly arranged through a second branch pipe on the top of the boosting regulating plate. A pressure regulating pipe is fixedly arranged through one side of the boosting regulating plate. A solenoid valve is installed on the pressure regulating pipe. A vertical block is fixedly arranged inside the boosting regulating plate near the pressure regulating pipe. A water pressure sensor is fixedly arranged on the side of the vertical block away from the pressure regulating pipe.

[0006] Furthermore, the water pressure sensor is electrically connected to the CPU controller, and the CPU controller is electrically connected to the solenoid valve. Mounting bases are fixedly installed on both sides of the bottom of the pump body.

[0007] Furthermore, a drive wheel is rotatably mounted on one side of the pump body, a drive rod is fixedly mounted on one side of the drive wheel, a collar is fixedly mounted on the other side of the pump body, and a cover is fixedly mounted on the outer wall of the collar.

[0008] Furthermore, the drive rod passes through the pump body and is rotatably sleeved within the sleeve, and the drive rod extends and rotatably is disposed within the sleeve cover. A drive mechanism is provided on one side of the drive wheel, and the drive mechanism drives the drive wheel to rotate via a belt.

[0009] Furthermore, a plunger is fixedly provided at one end of the upper tube, and a third branch tube is fixedly provided at the other end of the upper tube, with a sealing cap threaded onto the outer end of the third branch tube.

[0010] Furthermore, a mounting plate is provided on the front of the upper pipe, and drain pipes are respectively installed through the front and rear sides of the mounting plate, with drain valves installed on the drain pipes.

[0011] Furthermore, the outer surface of the pump body is coated with anti-rust paint, and the drive wheel, collar, and cover are all made of stainless steel. The collar is fixed to the outer wall of the pump body by positioning screws.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a water pressure sensor to monitor the fluid pressure inside the pressure regulating plate in real time and transmits the signal to the CPU controller. The CPU then automatically controls the opening and closing of the solenoid valve on the pressure regulating pipe according to a preset threshold, dynamically adjusting the fluid pressure inside the pressure regulating plate to achieve intelligent pressure boosting or depressurization without manual intervention, thus solving the problem of reliance on operator experience for manual adjustment.

[0013] The water pressure sensor of this invention can capture pressure fluctuations caused by changes in system flow, load and other operating conditions in real time. After receiving the signal, the CPU controller can quickly drive the solenoid valve to adjust the pressure in real time: when the pressure is lower than the set value, the solenoid valve closes slightly, reducing the liquid discharge from the pressure regulating pipe and increasing the pressure in the booster regulating plate, thereby increasing the output pressure of the upper pipe through the second branch pipe; when the pressure is higher than the set value, the solenoid valve opens wider, increasing the liquid discharge and reducing the pressure.
