Description

Technical Field

[0001] This utility model belongs to the field of metering pump calibration technology, and in particular relates to a calibration device for spinning metering pumps that can calibrate multiple pumps simultaneously. Background Technology

[0002] The spinning metering pump calibration device is a specialized piece of equipment used to test and calibrate the performance of spinning metering pumps. It is primarily used in the chemical fiber spinning industry to ensure that the metering pump can accurately control the delivery volume and stability of melts (such as polyester and nylon). This device tests the flow accuracy, pressure stability, repeatability, and durability of the metering pump by simulating actual spinning process conditions, thereby ensuring its reliability and consistency in the production process. However, the spinning metering pump calibration device still has the following drawbacks in practical use: During the operation of the spinning metering pump calibration device, the oil is directly transported to the receiving equipment through the pipeline. After a given time, the transport is stopped and the oil content is measured. However, during the transport of the oil, air bubbles may exist in the pipeline, which may affect the accuracy of the measurement. Secondly, during the calibration process of the spinning metering pump calibration device, when the metering pump has multiple output ends, multiple installation structures are required to cooperate. After metering, it is necessary to measure the flow rate of multiple output ends separately multiple times, which is not convenient. Utility Model Content

[0003] The purpose of this invention is to provide a calibration device for multiple spinning metering pumps that can be calibrated simultaneously. By setting up a mounting frame, mounting plate and oil receiving assembly, it solves the problems that the calibration process of metering pumps is prone to errors due to air in the pipeline, and that it is not convenient to calibrate metering pumps with multiple output ends.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a calibration device for multiple spinning metering pumps that can be calibrated simultaneously. It includes a mounting frame, a mounting plate, and an oil receiving assembly. Several parallel mounting plates are fixed to the front side of the mounting frame. An oil receiving assembly is symmetrically arranged through the upper part of each mounting plate. Several connectors are equally spaced through the upper part of each mounting plate. The connectors are located above the oil receiving assembly in the mounting plate where the connectors are fixed. An oil receiving box is fixed at the lower long edge of the front side of each mounting plate. During operation, the mounting plate is fixed on the mounting frame, and the equipment for testing the pumping efficiency of the metering pump is installed on the mounting plate. During operation, the oil receiving assembly collects the unevenly sprayed oil from the spray bend.

[0005] Furthermore, a reinforcing plate is symmetrically fixed to the rear side of the mounting frame, and a base is fixed to the bottom of the mounting frame and the reinforcing plate together. The reinforcing plate on the rear side of the mounting frame and the bottom base together form a stable support structure. The symmetrically distributed reinforcing plates enhance the anti-overturning ability of the mounting frame, while the base provides a fixed contact surface between the overall equipment and the working plane, ensuring the structural stability during operation.

[0006] Furthermore, each of the connectors is fixedly connected to a spray bend at its front end. The output end of the spray bend bends downwards. The spray bend connected to the front end of the connector adopts a downward bend design, which uses gravity to guide the flow of oil and ensures that the oil can fall accurately and vertically into the oil receiving container (measuring cup or oil receiving box 2) below, avoiding splashing.

[0007] Furthermore, a support frame is fixed at equal intervals on the lower part of the front side of the mounting plate. The support frame corresponds one-to-one with the connector. A measuring cup is movably connected to the top of the support frame. The measuring cup is positioned above the oil receiving box and below the oil receiving assembly. The support frame serves as the positioning mechanism for the measuring cup. Its equal-interval arrangement achieves precise alignment with the connector. The measuring cup adopts a movable connection method for easy and quick assembly and disassembly.

[0008] Furthermore, the top of the oil receiving box is open, a guide strip is fixed to the bottom of the oil receiving box, and an output pipe is fixedly connected to a corner of the bottom of the oil receiving box. The oil receiving box adopts a fully open top design to expand the oil receiving range. The internal guide strip guides the overflowing oil to the output pipe for centralized recovery through a sloping structure. The design of the output pipe at the corner optimizes the drainage efficiency and forms a closed oil recovery channel by directly connecting it to the recovery equipment.

[0009] Furthermore, the oil receiving assembly includes an oil receiving box II, a cylinder, and an oil outlet pipe. A cylinder is symmetrically arranged at the rear of the oil receiving box II. The cylinder is fixed to the rear side of the mounting plate, and its telescopic end passes through the mounting plate and extends outwards. The telescopic ends of the two cylinders included in the same oil receiving assembly are respectively fixed to the rear side of the oil receiving box II. Guide strips are symmetrically fixed to the bottom of the two oil receiving boxes II in front of the same mounting plate. An oil outlet pipe is fixedly connected to the bottom of the oil receiving box II outside the guide strips. The oil receiving assembly uses the cylinder-driven oil receiving box II as a transition container. The horizontal movement stability is ensured by the synchronous push of the two cylinders. The symmetrical guide strips inside the oil receiving box II enable the oil to quickly collect into the oil outlet pipe.

[0010] This utility model has the following beneficial effects: This invention solves the problem of calibration errors caused by air in the pipeline during the metering pump calibration process by setting up a mounting bracket, mounting plate, and oil receiving assembly. The cylinder is activated, driving the second oil receiving box to move until it is pushed below the output end of the spray bend. The connector is then connected to the output end of the metering pump, and the metering pump is started. The pump outputs oil into the connector, which then sprays it into the second oil receiving box through the spray bend at the front end of the connector. During operation, once the spray bend has stabilized its oil output, the cylinder is activated, driving the second oil receiving box to return to its original position. This design minimizes calibration errors during the metering pump calibration process.

[0011] This invention solves the problem of inconvenient calibration of metering pumps with multiple output ends during the calibration process by setting up a mounting bracket and mounting plate. After the mounting heads and rear ends of the connectors of each output end of the metering pump are installed and connected, and after a continuous and stable output of oil in the spray bend is achieved, the oil is output into a measuring cup and timing is started. After the set output time, the metering pump is turned off, and the measuring cups corresponding to each spray bend are removed to determine the amount of oil sprayed from the corresponding spray bend and measure the oil injection efficiency of the metering pump. This makes the calibration of metering pumps with multiple output ends more convenient. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0016] Please see Figure 1-4 This utility model is a calibration device for multiple spinning metering pumps that can be calibrated simultaneously. It includes a mounting frame 1, mounting plates 2, and oil receiving components 3. Several parallel mounting plates 2 are fixed to the front of the mounting frame 1, which mounts and fixes the mounting plates 2 on them. The mounting plates 2 support and fix the structure of the small-scale metering pump. Each mounting plate 2 has a symmetrically arranged oil receiving component 3 in its upper part, which holds the initially output oil. Several connectors 201 are also fixedly arranged at equal intervals in the upper part of each mounting plate 2. During operation, connector 201 connects to each output end of the metering pump, allowing the oil pumped by the metering pump to be delivered to the oil receiving assembly 3 or the measuring cup 203. Connector 201 is located above the oil receiving assembly 3 inside the mounting plate 2 on which connector 201 is fixed. Each mounting plate 2 has an oil receiving box 204 fixed at the lower long edge of its front side. During operation, the oil receiving box 204 receives the oil overflowing from the measuring cup 203, preventing the oil overflowing from the measuring cup 203 from leaking onto the front side of the mounting plate 2 located below the oil receiving box.

[0017] Specifically, a reinforcing plate 101 is symmetrically fixed to the rear side of the mounting frame 1, and a base 102 is fixed to the bottom of the mounting frame 1 and the reinforcing plate 101. The mounting frame 1 increases the stability of the support through the reinforcing plate 101, and the mounting frame 1 is supported and set on the working plane through the base 102.

[0018] Furthermore, each connector 201 is fixedly connected to a spray bend 2011 at its front end. The output end of the spray bend 2011 is bent downwards. When the connector 201 is in operation, the oil output from the connector 201 is output through the spray bend 2011.

[0019] Furthermore, support frames 202 are fixed at equal intervals on the lower front side of the mounting plate 2. The support frames 202 correspond one-to-one with the connectors 201. A measuring cup 203 is movably connected to the top of the support frame 202. The measuring cup 203 is located above the oil receiving box 204 and below the oil receiving assembly 3. The mounting plate 2 is supported by the support frame 202 and movably connected to the measuring cup 203 on the mounting plate 2. The measuring cup 203 receives the oil output from the metering pump output end mounting head sprayed from the spray bend 2011 and measures the amount of oil output within a given working time.

[0020] The operation process of this embodiment is as follows: During operation, firstly, the mounting heads of each output end of the metering pump are installed and connected to the rear end of the connector 201. After the continuous and stable oil is output from the spray bend 2011, the oil is output into the measuring cup 203 and the timing is started. After the set time is output, the metering pump is turned off, the measuring cup 203 corresponding to each spray bend 2011 after oil injection is removed, the amount of oil sprayed from the corresponding spray bend 2011 is determined, and the oil injection efficiency of the metering pump is measured. Specific Implementation Example 2

[0021] Please see Figure 1 , 3 4, 5. Based on the specific embodiment one, the top of the oil receiving box 204 is open, the bottom of the oil receiving box 204 is fixed with a guide strip 205, and an output pipe 206 is fixedly connected to a corner of the bottom of the oil receiving box 204. When the oil receiving box 204 is working, the guide strip 205 guides the oil falling into it to the output pipe 206. The bottom end of the output pipe 206 is connected to the oil recovery equipment to output the oil falling into the oil receiving box 204.

[0022] Specifically, the oil receiving assembly 3 includes an oil receiving box 301, a cylinder 302, and an oil outlet pipe 303. The cylinder 302 is symmetrically arranged behind the oil receiving box 301 and is fixed to the rear side of the mounting plate 2. The telescopic end of the cylinder 302 passes through the mounting plate 2 and extends outwards. The telescopic ends of the two cylinders 302 included in the same oil receiving assembly 3 are respectively fixed to the rear side of the oil receiving box 301. Guide strips 205 are symmetrically fixed to the bottom of the two oil receiving boxes 301 in front of the same mounting plate 2. The bottom of the oil receiving box 301 outside the guide strips 205 is fixedly connected to the oil outlet pipe 303. The bottom end of the oil outlet pipe 303 at the bottom of the oil receiving box 301 is connected to the oil recovery equipment. The oil entering the oil receiving box 301 is concentrated into the oil outlet pipe 303 through the guide strips 205. The oil receiving box 301 is driven by the cylinder 302 to a position below the output end of the spray bend pipe 2011 to receive the oil.

[0023] The operation process of this embodiment is as follows: During operation, cylinder 302 is started, and cylinder 302 drives oil receiving box 301 to move until the oil receiving box is pushed below the output end of the spray bend 2011. Then, connector 201 is connected to the output end of metering pump, metering pump is started, metering pump outputs oil into connector 201, and sprays it into oil receiving box 301 through the spray bend 2011 at the front end of connector 201. During operation, after the spray bend 2011 stably outputs oil, cylinder 302 is started, and cylinder 302 drives oil receiving box 301 to move back to its original position (the rear side of oil receiving box 301 contacts the front side of mounting plate 2), exposing the output position of spray bend 2011, so that the oil sprayed from spray bend 2011 falls into the corresponding measuring cup 203. For different metering pumps, multiple structures on mounting plate 2 are used to cooperate to perform multiple metering pump metering.
