Embodiment Construction

[0012] The invention provides a method for measuring the water volume of each wall-attached signal of a full-jet nozzle. In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, first, a full-jet sprinkler head with external signal water was selected as the test prototype. To the signal water, set the working pressure of the nozzle to 250kPa, so that the full-jet nozzle can be kept in a stable working state. After the nozzle has been working stably for 20 minutes, the test data is measured.

[0014] Next, read the total number of times of wall attachment during the working process of the full-jet nozzle 100 times, and record the time spent, repeat the above measurement work 3 times, and measure the time spent as 56.73s, 60.26s, and 58.65s respectively. According to the meas...

Abstract

The invention relates to a complete fluidic sprinkler parameter measurement method, in particular to a method for measuring the each-time wall attachment signal water flow rate of a complete fluidic sprinkler. The method comprises the following steps of: firstly connecting the signal nozzle of the complete fluidic sprinkler with a water inlet nozzle via a conduit to keep the complete fluidic sprinkler at the stable working state; then, reading the total wall attachment time n of the complete fluidic sprinkler in the working process, meanwhile, recording time t cost by the complete fluidic sprinkler, repeating the measurement work for m times to obtain average time t', and obtaining time T for carrying out wall attachment each time; keeping the connection of the conduit and the signal nozzle, disconnecting the conduit and the water inlet nozzle, and measuring signal water amount q which can be received in the corresponding time t'; and dividing the received signal water amount q by the read total wall attachment time n of the complete fluidic sprinkler, and then dividing by the time T for carrying out wall attachment each time, wherein the obtained q'=q / (nT) is the each-time wall attachment signal water flow rate of the complete fluidic sprinkler.

Description

technical field [0001] The invention relates to a method for measuring parameters of a full-jet nozzle, in particular to a method for measuring the water flow rate of each wall-attached signal of a full-jet nozzle. Background technique [0002] The full-jet nozzle is a new type of water-saving irrigation equipment with a new structure and a new working principle. It includes two states of direct spraying and wall attachment during the working process. The initial state of the full-jet sprinkler head is in a direct state. When one side of the sprinkler head obtains sufficient signal water flow, a low pressure is formed on the side, and a pressure difference is formed on both sides of the sprinkler head, so that the water flow is in a wall-attached state to promote the rotation of the sprinkler head. [0003] For full-jet nozzles, the amount of signal water flow determines whether the nozzle can successfully complete the rotation work, and directly affects its important hydrau...
