Problems solved by technology
[0003] At present, flow and pressure sensors are usually used to measure the flow and outlet pressure of the pump, and torque and speed sensors are used to measure the power of the pump. However, the flow rate of the three-cylinder pump is small, and the measurement error of the flowmeter is large. The price is expensive, and it can only be measured after a steady flow, and the real-time performance is not good
In addition, due to the different types of applied products, the dimensions of the three-cylinder pumps vary greatly, and there is a lack of a common installation platform for testing

Embodiment Construction
[0016] In order to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, see Figure 1 to Figure 4 :
[0017] In order to test the pressure, flow, power, efficiency and other performance indicators of the three-cylinder pump, a test system with high degree of automation and strong versatility is developed by using technologies such as sensors, computer control and mechatronics. The system mainly includes the following three parts:
[0018] 1. Four degrees of freedom pump installation platform
[0019] The currently used three-cylinder pump installation platform can only adjust the degree of freedom in the height direction, and the adjustable height is limited, and the left and right and front and rear directions can only be adjusted by pressing blocks. In the actual detection work, this structure greatly limits the number of triplex pump ...

The invention relates to automatic test technology, in particular to a three cylinder pump test device. A three cylinder pump is mounted in a pump mounting platform with multiple freedom degrees and is driven through a frequency conversion motor; a rotating speed and torque tester is arranged between the three cylinder pump and the frequency conversion motor; the water sucking pipe of the three cylinder pump is communicated with a water pond through an overflow pipe, the water discharging pipe of the three cylinder pump is communicated with a water incoming pipe of a weighting flow testing mechanism, and the water outlet of the three cylinder pump is provided with a pressure sensor and a temperature sensor through a buffering tank. According to the device, the pump mounting platform with four freedom degrees, and the platform has adjusting functions of vertical height, transverse positions and rotating angles; the flow testing system meters by the weighting method, the mass measuring error rarely exceeds 0.05%, the metering accuracy is higher than that of an ordinary meter, and cost is low; the entire device controls and acquires pump performance parameters automatically, original manual operation, control, metering and calculation are completed by a computer, and intelligence of the system is realized.
Description
technical field [0001] The invention relates to the technical field of electromechanical testing, in particular to a device for testing the performance index of a three-cylinder pump for a sprayer and a washing machine. Background technique [0002] Three-cylinder pumps are divided into three-cylinder plunger pumps and three-cylinder piston pumps, which have been widely used in sprayers, cleaning machines, cleaning pumps, plunger pumps, motorized sprayers and other products. It is used for cleaning and maintenance of automobiles, trains, tanks, ships and other motor vehicles, construction machinery and agricultural machinery, and can be used for livestock, poultry farms, zoos, commercial centers, vegetable markets, swimming pools, gymnasiums, etc. As well as garden watering, sanitation and epidemic prevention, etc. The main parameters that affect the quality of these products are pressure, flow and power, etc., so it is very necessary to sample the pressure, flow, power and...
