Description

Technical Field

[0001] The invention relates to the field of mechanical pumps, in particular to a novel pump head structure of a high-pressure cleaning pump. Background Art

[0002] This device is a high-pressure cleaning pump used on ships. The high-pressure cleaning pump is the core component of the ship's high-pressure cleaning machine. The structural design and working principle of its pump head are directly related to the performance and efficiency of the cleaning machine. The pump head of the high-pressure cleaning pump is the core component of the high-pressure cleaning machine, responsible for pressurizing water or other cleaning agents and spraying them out. The pump head is usually composed of key components such as a water inlet, a water outlet, a piston, a sealing ring, a one-way valve, etc. When in use, the efficiency of the high-pressure cleaning pump can be increased by improving the above components;

[0003] Comparative Document 1: The existing Chinese patent with the publication number CN108518328B discloses a high-pressure pump head for a mud pump, including a pump head housing, a piston rod and a ball. A fixed seat is arranged on the right outer side of the pump head housing, and a linear bearing is installed on the right side of the pump head housing. A pipe connection seat is installed in front of the pump head housing outside the water delivery hole through a second sealing ring for sealing. A bracket is installed inside the pipe connection seat at the front end of the water inlet pipe connector, and a ball is placed inside the space between the bracket and the water delivery hole. A pipe connection seat is installed behind the pump head housing outside the water delivery hole, and a water delivery pipe connector is installed inside the pipe connection seat. The high-pressure pump head of the mud pump adopts a rotatable and adjustable adjusting bolt fixed to the rear of the pump head and connected to the piston cavity to form an adjustable piston chamber, forming a pressure adjustment change, ensuring that the equipment can move under high pressure, and can better carry out the mud pump's transportation work, promoting the development of the mud pump industry;

[0004] However, the new high-pressure cleaning pump head structure still has the following defects:

[0005] 1. It is not possible to detect the changes in the internal liquid pressure of the high-pressure cleaning pump in time. The core requirement of the high-pressure pump is that the output pressure must not be lower than 250MPa. However, in actual work, the high-pressure stress borne by parts at different altitudes is also different. When the high-pressure cleaning pump is in water, the water pressure will also increase the actual pressure borne by the pump body. Excessive pressure on the pump body and uneven pressure on the pump body will cause wear of the pump head and affect the life of the pump head.

[0006] 2. The pump head of the cleaning pump is in contact with water, air and chemical cleaning agents for a long time, which is prone to oxidation, corrosion and rust. Traditional sandblasting for rust removal is costly, not environmentally friendly, and highly toxic, which has an impact on the user's health. Summary of the invention

[0033] The present invention provides a novel high-pressure cleaning pump head structure through improvement, which has the following improvements and advantages compared with the prior art:

[0034] Firstly, by starting the first motor to drive the pulley transmission, the connecting rod drives the transmission gear and the connecting rack transmission, and the meshing transmission drives the connecting sliding rods on both sides of the connecting rack to slide and retract in the high-pressure pump head, and by pushing the piston to make reciprocating motion in the high-pressure pump head, the volume of liquid in the pump chamber changes continuously during the movement of the piston, thereby realizing the functions of suction and discharge while increasing the water pressure, thereby increasing the flow rate of the cleaning pump, so that the high-pressure water inside the cleaning pump can pass through the high-pressure pump head to repeatedly flush the high-pressure pump head and the pump head cover to clean the pump head and the rust caused by seawater oxidation, thereby achieving a self-cleaning effect. In addition, the second detection pressure gauge and the first detection pressure gauge can timely detect the pressure value of the liquid when passing through the pump head cover and the high-pressure pump head, and can timely control the pressure of the liquid when passing through the pump head cover. The installation of two sets of pressure regulating valves can help finely control the pressure to avoid excessive pressure. Waste of resources and damage to equipment, and the second regulating valve and the first regulating valve are convenient for timely adjusting the water outlet pressure according to actual needs. In addition, the pressure value of the single-side high-pressure pump head can be measured and controlled through the first pressure outlet pipe. Because the second regulating valve is connected, the second pressure outlet pipe measures the total pressure of the pump chamber when the liquid passes through. The other two groups of side main cavity connectors are connected to the two groups of high-pressure pump heads through the diversion connecting pipe. The purpose is also to timely adjust the pressure on the pump heads on both sides. Because the damage of the pump is generally not due to excessive pressure, but the uneven pressure inside the pump body causes cracks due to pressure difference. The first detection pressure gauge and the second detection pressure gauge are used to increase the intelligence of the device, realize automatic control and fault warning intelligent modification, thereby improving work efficiency and safety, reducing errors and risks of manual operation, and adding a booster pump to the water inlet pipeline to ensure stable and sufficient water inlet and reduce wear caused by water quality problems.

[0035] Secondly, the heat dissipation component is used to assist in heat dissipation. The height of one side of the supporting base plate is adjusted by adjusting the position of the connecting nut, so that the first motor and the pump body at the bottom are separated to facilitate further heat dissipation.

[0036] Thirdly, by improving the installation of multiple sets of sealing rings and springs inside the liquid cylinder body, the sealing effect of the pump head can be improved. The function of the low-pressure disk sealing ring is to ensure the sealing of the pump chamber and prevent pressure water leakage. The function of the V-shaped sealing ring is to further strengthen the sealing of the alloy plunger during activity, and the one-way valve ensures the correct direction of water flow to prevent backflow.

[0076] Among them, an alarm sounder 6 is installed on one side of the top of the pump head cover plate 411.

[0077] Working principle: First, the booster pump 205 at the middle position of the air pressure balance conduit 204 is connected to the water inlet, and the channel through which the cleaning agent enters the pump head is connected to the water source. Then the water source passes through the first regulating valve 202 and the pressure inlet pipe 203. At this time, the first detection pressure gauge 201 displays the water pressure, and the water flows from the high-pressure pump head 410 into the main reaction pump housing 418. The first motor 401 is driven by a pulley, and the connecting rod 406 drives the transmission gear 416 and the connecting rack 417. The connecting sliding rods 415 on both sides of the connecting rack 417 are driven to slide and retract in the high-pressure pump head 410 through the meshing transmission. The piston is pushed to make reciprocating motion in the high-pressure pump head 410. During the movement of the piston, the volume of liquid in the pump chamber changes continuously, thereby realizing the functions of suction and discharge while increasing the water pressure.

[0078] Then, the water flows through the high-pressure pump head 410 on the other side and is discharged from the second pressure outlet pipe 305, and then enters the second regulating valve 302. The second detection pressure gauge 301 at the top of the second regulating valve 302 detects the pressure of the water, and then re-enters the cavity from the first pressure outlet pipe 304 on the other side. When the cleaning pump completes the work, the liquid is discharged from the support base 303. The function of the first pressure outlet pipe 304 is to detect the water pressure of the high-pressure pump head 410 on one side after closing the second pressure outlet pipe 305 on one side. The water flows in the main reaction pump housing 418 through the second detection pressure gauge 301 and the first detection pressure gauge 201, so as to achieve the function of cleaning the high-pressure pump head 410. The water outlet connected to the bottom end of the support base 303 is the channel for spraying the pressurized cleaning agent, which is connected to a high-pressure hose or a spray gun.

[0079] Finally, the heat dissipation component 5 is used to assist in heat dissipation. The support base plate 501 is adjusted by adjusting the position of the connecting nut 503 to adjust the height of one side of the support base plate 501, so that the first motor 401 and the pump body at the bottom are separated to facilitate further heat dissipation.
