Description

Technical Field

[0001] This application relates to the field of silent pumps, and more particularly to a silent pump. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals.

[0003] Currently, Chinese utility model patent CN208982370U discloses a silent pump, including a pump body and a silent housing. The pump body is provided with an inlet pipe and an outlet pipe. The pump body is disposed inside the silent housing. The silent housing is provided with a first opening for the inlet pipe to pass through and a second opening for the outlet pipe to pass through. A sound-reducing layer is provided inside the silent housing. This utility model has the effect of reducing noise.

[0004] Since the water pump operates by rotating the motor, the water pump will vibrate, and the vibration of the water pump will cause the soundproof box to vibrate, resulting in a large amount of noise from the soundproof box itself. Utility Model Content

[0005] To reduce the noise generated by the soundproof enclosure, this application provides a silent pump.

[0006] This application provides a silent pump, which adopts the following technical solution:

[0007] A silent pump includes a pump body, a silent housing, and a buffer assembly. The buffer assembly includes a mounting component, a buffer plate, and a buffer spring. The buffer plate is slidably connected to the silent housing in a vertical direction. The mounting component is disposed on the buffer plate and is used to install the pump body onto the buffer plate. The buffer spring is used to maintain a distance between the buffer plate and the inner bottom wall of the silent housing.

[0008] By adopting the above technical solution, the pump body is installed on the buffer plate through the mounting parts. During the operation of the pump body, the pump body will vibrate, and the vibration of the pump body will cause the buffer plate to shake up and down. The shaking of the buffer plate is absorbed by the buffer spring, reducing the vibration of the soundproof box and reducing the noise emitted by the soundproof box.

[0009] Optionally, the mounting component includes a mounting plate, a sliding plate, a first sliding spring, a second sliding spring, and a snap-fit ​​ring. The sliding plate is slidably connected to the buffer plate in a horizontal direction. The first sliding spring is used to reduce the movement of the sliding plate relative to the buffer plate. The mounting plate is slidably connected to the sliding plate in a horizontal direction perpendicular to the sliding direction of the sliding plate. The second sliding spring is used to reduce the movement of the mounting plate relative to the sliding plate. The snap-fit ​​ring is disposed on the mounting plate and is used to snap the pump body.

[0010] By adopting the above technical solution, the snap ring is used to snap the pump body, the mounting plate, the sliding plate and the buffer plate slide against each other, the first sliding spring and the second sliding spring are used to reduce the movement of the mounting plate and the sliding plate; when the pump body is working, the pump body will vibrate, the first sliding spring and the second sliding spring are used to reduce the vibration of the pump body on the horizontal plane, and the buffer spring reduces the vibration of the pump body in the vertical direction, thereby reducing the vibration of the pump body in three-dimensional space.

[0011] Optionally, the inner sidewall of the snap ring is disposed on the snap block, and the sidewall of the pump body is provided with a snap groove, which is used to snap into the snap block.

[0012] By adopting the above technical solution, the snap-fit ​​block engages with the snap-fit ​​groove on the pump body, reducing the possibility of the pump body rotating during operation.

[0013] Optionally, the soundproof enclosure is further provided with a balancing component to reduce pump body tilt. The balancing component includes a sleeve, a first sliding rod, and a second sliding rod. The length direction of the first sliding rod is parallel to the sliding direction of the sliding plate, and the first sliding rod is slidably connected to the inner wall of the soundproof enclosure. The length direction of the second sliding rod is parallel to the sliding direction of the mounting plate, and the second sliding rod is slidably connected to the inner wall of the soundproof enclosure. The sleeve is connected to the first sliding rod and the second sliding rod, and the pump body is sleeved inside the sleeve.

[0014] By adopting the above technical solution, the pump body may detach from the locking ring during vibration. The balance component and the locking ring keep the pump body in a vertical position. The sleeve is fitted onto the pump body, and the first sliding rod and the second sliding rod realize the horizontal movement of the sleeve, which better matches the vibration of the pump body.

[0015] Optionally, the inner wall of the sleeve is provided with a plurality of balls, which are used to abut against the pump body.

[0016] By adopting the above technical solution, the vibration of the pump body during movement will have a vertical displacement. The relative sliding between the pump body and the sleeve is achieved by the ball bearings, thereby reducing the wear of the pump body.

[0017] Optionally, the soundproof enclosure includes a housing, a cover, and several bolts. The cover is used to seal the opening of the housing, and the bolts are used to connect the cover to the housing.

[0018] By adopting the above technical solution, the structure of the box and cover is simple, enabling the pump body to be placed inside the soundproof box. The box and cover are connected by bolts, which reduces the noise generated by the pump body from spreading outside the box.

[0019] Optionally, the pump body is provided with two water pipes, which are an inlet pipe and an outlet pipe, respectively. Both water pipes pass through the cover and are provided with corrugated sections.

[0020] By adopting the above technical solution, two water pipes are used for water inlet and outlet respectively. The structure is reasonable. Since the pump body will vibrate, the corrugated section on the water pipe absorbs the vibration of the pump body, ensuring that the water pipe can be stably connected to the equipment.

[0021] Optionally, the water pipe is provided with a connector for connecting to the cover. The connector includes an abutment plate and a connecting nut. The abutment plate abuts against one side of the cover, and the connecting nut is threaded onto the water pipe and abuts against the other side of the cover.

[0022] By adopting the above technical solution, the connector is used to connect the water pipe to the cover. The abutment plate on the water pipe abuts against the cover, and then the bolt is tightened onto the water pipe to fix the water pipe to the cover. The structure is simple and easy to operate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The buffer assembly reduces the transmission of pump body vibration to the soundproof enclosure, thereby reducing the vibration of the soundproof enclosure and thus reducing the noise of the soundproof enclosure;

[0025] 2. The balancing component is used to keep the pump body in a vertical position and improve the balance of the pump body during vibration;

[0026] 3. The water pipe on the pump body has a corrugated section, which allows the water pipe to move relative to the pump body. Attached Figure Description
