Description

TECHNICAL FIELD

[0001] The present application relates to the field of plunger pumps, in particular, to a cleaning device of a plunger pump. BACKGROUND

[0002] The plunger pump is an important device of the hydraulic system, which relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working cavity to realize oil suction and oil compression. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow regulation, and is widely used in high-pressure, large-flow and flow-regulated occasions, such as hydraulic machines, engineering machinery and ships. The existing plunger pump connecting pipeline is a closed structure. In the process of conveying water, impurities in the water deposit inside the connecting pipeline, causing blockage. For example, a plunger pump capable of effectively cleaning the pump body connecting pipeline in Chinese patent application No. CN202222523022.9 includes a plunger pump body. A plunger movable pipeline is arranged on one side outer wall of the plunger pump body. A pump body connecting pipeline is fixedly connected to the outer wall of the plunger movable pipeline away from the plunger pump body through bolts. A first stop valve and a second stop valve are arranged at the bottom of the pump body connecting pipeline. The first stop valve is located on one side of the second stop valve, and a cleaning pipe is arranged between the first stop valve and the second stop valve. The plunger pump capable of effectively cleaning the pump body connecting pipeline can clean the impurities by disassembling and assembling the sealing screw cap. The sealing screw cap can ensure its sealing property by single multi-thread screwing, and the connection is more closely fitted, reducing the gap during disassembly and assembly, thereby reducing the problem of reducing the internal negative pressure of the pump body connecting pipeline and the plunger movable pipeline, and ensuring the stable conveying of water flow.

[0003] However, the above-mentioned scheme still has certain defects. First, the filter screen is arranged inside the pump body connecting pipeline. The filter screen needs to be cleaned after long-term use, otherwise the filtering effect will be affected. Special tools are needed to disassemble the pump body connecting pipeline, and the disassembly and assembly process is relatively cumbersome, thereby reducing the practicability.

The cleaning pipe 140 is connected to the connecting pipe 130. An arc groove 131 is provided on one side of the connecting pipe 130, and a sealing arc plate 210 is slidably connected to the arc groove 131. The arc groove 131 can serve as a limit. A one-way inlet valve 132 and a one-way outlet valve 133 are provided on one side of the connecting pipe 130. The one-way inlet valve 132 is connected to an external water inlet pipe, and the one-way outlet valve 133 is connected to an external drain pipe. When the plunger pump body 110 is powered on, liquid passes through the one-way inlet valve 132 and enters the connecting pipe 130, which can serve as a control function.

[0032] In some specific implementations, a first shut-off valve 141 is provided on one side of the cleaning pipe 140, and a second shut-off valve 142 is provided on the other side of the cleaning pipe 140. When it is necessary to clean the impurities in the cleaning pipe 140, the first shut-off valve 141 and the second shut-off valve 142 are closed, cutting off the connection between the cleaning pipe 140 and the connecting pipe 130. A sealing threaded cap 143 is provided on one side of the cleaning pipe 140. By unscrewing the sealing threaded cap 143, the impurities deposited in the cleaning pipe 140 can be cleaned, and the plunger pump body 110 can continue to work.

[0033] Please see Figure 1 , Figure 3 and Figure 4 The filter assembly 200 includes a sealing arc plate 210, a filter plate 220, an elastic bracket 230, and a fixed shell 240. The sealing arc plate 210 is slidably connected to the connecting pipe 130, and the filter plate 220 is fixedly connected to the sealing arc plate 210. The filter plate 220 is slidably connected to the connecting pipe 130. The elastic bracket 230 is disposed at both ends of the sealing arc plate 210, and the fixed shell 240 is disposed on both sides of the connecting pipe 130. The elastic bracket 230 and the fixed shell 240 are slidably engaged. The sealing arc plate 210 includes an arc plate 211, a fixed plate 212, and a sealing strip 213. The fixed plate 212 is fixedly connected to the arc plate 211, and the sealing strip 213 is disposed on both sides of the fixed plate 212 and contacts the arc groove 131. The fixed plate 212 can play a connecting role, and the sealing strip 213 can play a sealing role.

[0034] In some specific implementations, the filter plate 220 includes a circular plate 221 and a filter screen 222. The filter screen 222 is disposed on one side of the circular plate 221 and can be connected through the circular plate 221. The filter screen 222 can filter impurities. The elastic bracket 230 includes a connecting plate 231, a cylinder 232, an arc block 233, and a spring 234. The cylinder 232 is disposed at both ends of the connecting plate 231, and the arc block 233 is slidably connected to the cylinder 232. The spring 234 is disposed at... Placed inside the cylinder 232, the spring 234 is fixedly connected to the arc block 233. When the filter screen 222 needs to be disassembled and cleaned, the arc plate 211 is pulled, and the upward force causes the fixed shell 240 to squeeze the arc block 233, causing the arc block 233 to move into the cylinder 232. Then the arc block 233 and the groove inside the fixed shell 240 are misaligned, and the filter screen 222 can be taken out from the inside of the connecting pipe 130. The reverse operation can be used to install it.

[0035] The working principle of the plunger pump cleaning device is as follows: Connect the plunger pump body 110 to an external power source, connect the one-way inlet valve 132 to an external water inlet pipe, and connect the one-way outlet valve 133 to an external drain pipe. When the plunger pump body 110 is powered on, liquid passes through the one-way inlet valve 132 into the connecting pipe 130. The filter plate 220 filters impurities in the liquid within the connecting pipe 130, preventing impurities from entering the moving pipe 120 and causing plunger wear. Impurities in the connecting pipe 130 are deposited at the bottom of the cleaning pipe 140. The cleaning pipe 140 provides a deposition space for impurities in the liquid. Unscrew the sealing threaded cap 143. Impurities deposited inside the cleaning pipe 140 can be cleaned, ensuring the continuous operation of the plunger pump body 110. When the filter screen 222 needs to be disassembled and cleaned, the upward force of pulling the arc plate 211 causes the fixed shell 240 to squeeze the arc block 233, causing the arc block 233 to move into the cylinder 232. Subsequently, the arc block 233 and the groove inside the fixed shell 240 are misaligned, allowing the filter screen 222 to be removed from the connecting pipe 130. The reverse operation can be performed to install it. Thus, the filter plate 220 can be disassembled and installed without the use of special tools, making the disassembly and installation process more convenient and improving its practicality.
