Structural design and configuration
Rain test device It is composed of rain swing pipe splashing device, flushing device, swing pipe bracket, swing pipe transmission mechanism, working rotary table, electrical control and other parts. The swing tube rain test device is made of high-quality stainless steel and angle iron. The equipment consists of the electrical control part of the working rotating table of the column swing tube swing tube transmission mechanism. The swing tube bracket, box, etc. are all made of stainless steel plates. The swing tube does not shake when swinging. The flange joints of the sample holder of the rotating stage and other accessories of the equipment are made of stainless steel. The surface of the rotating stage is made of aluminum plate or hard material.
This equipment is designed to install a swing tube with a radius of mm to meet the needs of large-size specimen testing. The nozzle is a detachable special nozzle. The nozzle hole can be replaced and the direction of the water spray can be adjusted. The water droplets ejected have a uniform flow rate and sufficient flow. The transmission device of the swing tube is reasonably designed and made with precision. It is driven by an advanced stepper motor acceleration and decelerator. The swing angle frequency can be directly set on the instrument device. It is controlled by a controller and is simple to operate, avoiding the inaccuracy and cumbersome manual adjustment by feeling of similar equipment in the past.
The swing tube and bracket are connected by flange, which is very convenient to install and disassemble. The swing tube is made of an industrial stainless steel pipe with an inner diameter and can swing back and forth. At the same time, water controlled at a certain flow rate and pressure is sprayed through the nozzle on the swing tube to conduct water tests on the test samples.
The swing of the pendulum tube is completed by an advanced stepper motor. The rotation frequency and angle and the speed of the turntable are automatically controlled by a programmable liquid crystal controller. After setting the pendulum tube swing speed and angle, the screen will run according to the set value. easy to use. The sample rack turntable rotates horizontally. The entire equipment is reasonably designed and durable. On the premise that the equipment meets national standards and has stable performance in all aspects, it is more practical and easy to control, avoiding the inaccuracy and cumbersome manual adjustment of similar equipment in the past.
The equipment is equipped with a set of water storage tanks of considerable capacity to supply the swing pipe water spray required for the test, which is resistant to pressure and corrosion. The water tank is covered to prevent dust and debris from entering. Equipped with water quality filter, water inlet float valve and drain valve.
Rotary workbench The rotary workbench is made of hard aluminum plate and hard materials to facilitate the installation of test specimens. The turntable is equipped with test specimen fixing bolts. The reducer is used to drive and adjust the speed to the rated speed. The rotating tabletop supports a weight of approx.
The electrical control cabinet is an independent control cabinet. Above it is the control panel. The touch screen button switches are placed here for easy operation and the working status is clear at a glance. Below is the strong and weak current distribution cabinet where various executive components are installed. Reasonable arrangement, clear direction and easy maintenance. The AC contactors and relays are all French Schneider brand products. Other components such as push buttons and switches are from well-known brands.
Waterway filter All sprayed water must be filtered before returning to the water storage tank to prevent impurities from entering the water storage tank. All test water uses local clean tap water sources. Before the water in the water storage tank enters the drip tray, a filtering device is added to ensure that the drip holes are not easily blocked.
The water pump adopts stainless steel multi-stage centrifugal pump to meet the needs and pressure requirements of different test water.
The flow meter uses a glass rotor flow meter to control the flow of water in real time.
The current water source pressure is displayed by a pressure gauge that displays the actual pressure.
The splash test device and the flush test device are controlled by the built-in electrical appliances, high-pressure water pump flow controller and manual valve of the swing pipe rain test device.
Control system
This set of swing tube rain shower equipment uses a programmable liquid crystal controller to control the swing angle of the swing tube, swing speed, rotation speed, pressure, flow time of the turntable, etc. to effectively ensure that the test operates according to standards. The control system is equipped with Schneider actuators. The device
is composed of a measurement control system. This operating system is developed by our company and has the advantages of simple operation, stable performance and intuitive interface. Its perfect combination with the control system of the splash test device and flush test device can meet the test requirements to the greatest extent and effectively save costs.
This operating system is developed by our company. The independent control system of the swing tube water inlet turret has the advantages of simple operation, stable performance, and intuitive interface. Its perfect combination with the actuator can meet the test requirements to the greatest extent.
Operation mode: program controlled operation, single manual operation, scheduled shutdown, etc.
Human-machine interface Chinese interface menu color touch screen.
Controller analog acquisition module.
Set precision time seconds for worktable speed/water flow/swing tube swing angle and swing speed, etc.
The speed control method achieves the required speed through the reducer.
The angle control method drives the reducer through a stepper motor and changes the number of pulses of the stepper motor to achieve the required angle control.
The actuating components are AC contactor relays from Schneider of France.
The test water pressure turntable speed, swing tube swing amplitude and swing speed test time required for the test can all be set and controlled on the human-machine interface.
The controller has set up an unexpected power outage memory function for the device. After an unexpected power outage is restored, it can perform power restoration, stop cold start and restore, or hot start and restore.
