Description

Technical Field

[0001] The present application relates to the field of plunger pumps, and in particular to a plunger pump with electric heating and heat preservation. Background Art

[0002] The plunger pump is an important device in the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve oil suction and oil pressure. It has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment.

[0003] The plunger pump mentioned in the existing Chinese public patent (authorization announcement number: CN220285955U) includes: a frame, a rotating shaft is provided in the middle of the frame, two involute wheels are provided on the rotating shaft, and the protruding parts of the two involute wheels are arranged in reverse, and a volume shell is provided on the right side of the frame; a connecting rod, one end of the connecting rod is connected to the involute wheel, and the other end is provided with an elastic component located inside the volume shell; a plunger pump is provided, which drives the connecting rod to operate through the rotating shaft, simplifies the transmission structure, and has stable transmission. At the same time, the elastic component is used to eliminate the pulse force, ensure the stable operation of the structure, and extend the service life.

[0004] In order to meet the needs of existing plunger pumps, a hydraulic solenoid valve is often installed inside for pressure relief. However, the brittle material structural characteristics of the static iron core and the moving iron core in the hydraulic solenoid valve determine the pressure relief pressure of the plunger pump, which is easily damaged under a large pressure, resulting in a small pressure relief pressure of the plunger pump. When the pressure relief pressure is small, the plunger pump continues to operate, and a high temperature will be generated inside, which may easily cause the plunger pump to malfunction.

[0005] The purpose of the present application is to solve the problem in the above background technology that brittle materials such as the static iron core and the moving iron core in the existing hydraulic solenoid valve are easily damaged under high pressure. The present application provides a plunger pump with electric heating and heat preservation.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

After preparation, it will be put into use. During use, the buffer device will move accordingly to reduce the vibration frequency. At the same time, when the air pressure inside the plunger pump is too high, the pressure relief device will automatically relieve the pressure, thereby reducing the damage to the internal components of the plunger pump.

[0011] Furthermore, a restraining plate is fixedly installed inside the sliding tube, a sliding groove is provided on the surface of the restraining plate, and a diameter of the sliding groove is smaller than a diameter of the limiting plate.

[0012] By adopting the above technical solution, since the diameter of the constraint plate is smaller than the diameter of the limit plate, the limit plate can be limited to prevent the limit plate from falling into the interior of the plunger pump due to insufficient air pressure.

[0016] By adopting the above technical solution, the vibration frequency can be reduced by using a buffer device, thereby reducing the situation where the pipeline is loosened or falls off due to being at the vibration frequency for a long time.

[0017] Furthermore, a circular plate for connection is provided at the connection between the arc-shaped connection plate and the mounting track, and the upper surface of the circular plate is fixedly connected to the bottom of the mounting track.

[0018] By adopting the above technical solution, the buffer device and the mounting rail can be connected by using a circular plate, and at the same time, the buffer device is protected to prevent the mounting rail from directly contacting the buffer device and causing damage to the buffer device.

[0021] Furthermore, both sides of the surface of the pump body mounting platform are provided with limiting grooves, and the internal threads of the limiting grooves are penetrated by fixing cones.

[0022] By adopting the above technical solution and setting the fixing cone inside the limiting groove, it is convenient for personnel to fix the pump body mounting platform.

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

[0024] 1. In the present application, by setting up a plunger pump and a pressure relief device, when the internal air pressure of the plunger pump is relatively high, the air pressure will enter the sliding tube along the guide cover. When the gas enters the sliding tube, an upward force will be generated along the sliding tube to push the plug. When the plug moves, a gap will be generated between it and the sliding rod, and the gas will flow out through the gap between the sliding rod and the plug, thereby achieving the purpose of reducing the damage to the original hydraulic solenoid valve inside the plunger pump due to excessive air pressure, thereby improving the service life of the hydraulic solenoid valve.

[0025] 2. In the present application, by installing a buffer device at the bottom of the mounting track, the plunger pump will generate a certain vibration frequency during use. When vibrating, the pipe connected to the oil outlet pipe will vibrate accordingly. When the vibration frequency reaches a certain time, it is easy to cause the pipe connected to the oil outlet pipe to loosen or fall off. Installing a buffer device at the bottom of the mounting track can reduce the vibration frequency and reduce the occurrence of pipe falling off. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a plunger pump with electric heating and heat preservation.

[0034] Reference Figure 1 and Figure 2 A plunger pump with electric heating and heat preservation comprises a pump body mounting platform 1, a mounting groove is provided on one side in the middle of the surface of the pump body mounting platform 1, buffer devices 2 are provided on both sides of the interior of the mounting groove, plunger pumps 4 are fixedly installed on both sides of the surface of the pump body mounting platform 1 through mounting rails 3, a through groove is provided on the surface of the plunger pump 4, a pressure relief device 5 is fixedly installed inside the through groove, an electric heating pump 6 for heating is provided on one side of the surface of the plunger pump 4, an oil inlet pipe 7 is provided on one side of the top of the plunger pump 4, and an oil outlet pipe 8 for output is provided at one end of the plunger pump 4.

[0035] A heat dissipation frame is fixedly mounted on the surface of the electric heat pump 6 , a groove is provided on the surface of the heat dissipation frame, and a plurality of heat conducting plates are provided inside the groove.

[0036] In addition, both sides of the surface of the pump body mounting platform 1 are provided with limiting grooves, and the internal threads of the limiting grooves are penetrated and fixed.

[0037] When in use, after installing the plunger pump 4 in a suitable position, connect the surface of the oil outlet pipe 8 to the pipeline. During use, the buffer device 2 will move accordingly to reduce the vibration frequency. At the same time, when the air pressure inside the plunger pump 4 is too high, the pressure relief device 5 will automatically relieve pressure, thereby reducing the damage to the internal components of the plunger pump 4. Because different media will have different states and physical properties at different temperatures, the electric heating pump 6 keeps the transmission medium within the set temperature range to ensure the quality and efficiency of the production process. At the same time, the viscosity of some media will change when the temperature changes. The electric heating pump 6 can control the temperature of the medium, thereby maintaining the viscosity unchanged and improving the flow and efficiency of the pump. The heat dissipation frame on the surface of the electric heating pump 6 will export the heat energy generated by the electric heating pump 6 during working time.

[0038] Reference Figures 1 to 3 The pressure relief device 5 includes a sliding tube 501 fixedly installed inside the groove, one end of the sliding tube 501 is provided with a deflector 502, the interior of the sliding tube 501 is slidably connected with a plug 503, the interior of the plug 503 is rotatably connected with a fan 505 through a connecting rod 504, and limit plates 506 are fixedly installed on both sides of the surface of the plug 503.

[0039] A restraining plate 9 is fixedly installed inside the sliding tube 501 , and a sliding groove is provided on the surface of the restraining plate 9 . The diameter of the sliding groove is smaller than the diameter of the limiting plate 506 .

[0040] In addition, a rotation groove is provided inside the plug 503 , the size of which matches the size of the connecting rod 504 , and the rotation groove is T-shaped.

[0041] When the pressure inside the plunger pump 4 is too high, the air pressure inside the plunger pump 4 will enter the sliding tube 501 through the guide cover 502. When the air pressure enters the sliding tube 501, it will blow the fan 505. The fan 505 will rotate inside the plug 503 through the connecting rod 504. When rotating, the speed of the air pressure flow can be increased. The air pressure enters the bottom of the plug 503 through the sliding tube 501. The air pressure pushes the plug 503. When pushing, the plug 503 will The tube 501 slides, and during sliding, the air pressure will flow out through the gap between the sliding tube 501 and the plug 503. At the same time, the limit plates 506 installed on both sides of the plug 503 can limit the plug 503 through the constraint plate 9, thereby preventing the plug 503 from falling into the plunger pump 4 due to insufficient air pressure inside the plunger pump 4. In this way, the air pressure inside the plunger pump 4 can be eliminated, thereby reducing the damage of the original hydraulic solenoid valve inside due to excessive pressure.

[0042] Reference Figure 1 and Figure 4The buffer device 2 includes an arc-shaped connecting plate 201 fixedly installed at the bottom of the mounting track 3, the middle part of the arc-shaped connecting plate 201 is hinged, and damping rods 202 are fixedly installed at the bottom and the middle of both sides of the arc-shaped connecting plate 201, and the surface of the damping rod 202 is sleeved with a spring 203.

[0043] A circular plate 10 for connection is provided at the connection between the arc-shaped connection plate 201 and the mounting track 3 , and the upper surface of the circular plate 10 is fixedly connected to the bottom of the mounting track 3 .

[0044] During the operation of the plunger pump 4, the strong vibration frequency will be transmitted to the arc connecting plate 201 through the circular plate 10 at the bottom of the mounting track 3. When the arc connecting plate 201 is subjected to the vibration frequency, the damping rod 202 and the spring 203 at the bottom of the arc connecting plate 201 will expand and contract with the vibration frequency. During expansion and contraction, the spring 203 on the damping rod 202 will rebound accordingly. During rebound, the vibration frequency received will be buffered. At the same time, because the middle part of the arc connecting plate 201 is hinged, the arc connecting plate 201 will open to both sides. When opening, the damping rod 202 in the middle will be lifted up, and the damping rod 202 will contact the bottom of the mounting track 3. When in contact, the vibration frequency can be buffered, thereby reducing the loosening or falling off of the pipe on the plunger pump 4.

[0045] Working principle: When using the plunger pump 4, the plunger pump 4 is installed through the pump body mounting platform 1, and then the plunger pump 4 is connected to the power supply, and the plunger pump 4 will operate. During the operation, the vibration received will be transmitted to the buffer device 2 through the circular plate 10 at the bottom of the mounting track 3;

[0046] When the buffer device 2 is vibrated, the damping rod 202 and the spring 203 at the bottom of the arc-shaped connecting plate 201 will expand and contract with the vibration frequency. When expanding and contracting, the spring 203 on the damping rod 202 will rebound accordingly. When rebounding, the vibration frequency is buffered. At the same time, because the middle part of the arc-shaped connecting plate 201 is hinged, the arc-shaped connecting plate 201 will open to both sides. When opening, the damping rod 202 in the middle will be lifted up. The damping rod 202 will contact the bottom of the mounting track 3. When in contact, the vibration frequency can be buffered. When the plunger pump 4 works for a long time, the internal air pressure is too large, and the air pressure will be released through the pressure relief device 5.

[0047] When the pressure in the plunger pump 4 is released, the air pressure inside the plunger pump 4 will enter the sliding tube 501 through the air guide cover 502. When the air pressure enters the sliding tube 501, it will blow the fan 505, and the fan 505 will rotate inside the plug 503 through the connecting rod 504. During the rotation, the speed of the air pressure flow can be increased, and the air pressure enters the bottom of the plug 503 through the sliding tube 501. The air pressure pushes the plug 503. During the pushing, the plug 503 will slide through the sliding tube 501. During the sliding, the air pressure will flow out through the gap between the sliding tube 501 and the plug 503. At the same time, the limit plates 506 installed on both sides of the plug 503 can limit the plug 503 through the constraint plates 9, thereby reducing the situation where the plug 503 falls into the plunger pump 4 due to insufficient air pressure inside the plunger pump 4.
