1、打开折叠式水桶，注入介质为5-100℃的清水，然后接通电源待机。2

1. Open the collapsible bucket, inject clean water with a medium of 5-100°C, and then turn on the power and wait. <br>2. Connect the self-locking joint of the inlet pipe to the inlet seat of the pressure test pump, insert the return pipe into the outlet of the pressure regulating valve, and put the inlet pipe and the return pipe into the bucket. <br>3. Press the "Start" switch, stop the machine after the outlet has normal water flow, tighten the copper pressure relief knob under the pressure gauge, and connect the outlet high-pressure pipe. <br>4. After starting up and pressurizing the pipeline under test, slowly turn down the red knob on the pressure regulating valve. When the pressure value of the gauge reaches the required pressure of the pipeline (0-1.2MPA), lock the pressure-holding lock piece. Stop and keep pressure. <br>5. After the pressure is shut down, observe whether the pressure value drops. If the pressure value is lower than the required test value, the pressure can be restarted after starting. If there is still a pressure drop after the pressure compensation, check the connections and the measured value. Are there any leaks in the pipeline? <br>6. After the test is completed, disconnect the power supply, open the pressure relief valve switch to discharge the pressure, and loosen the pressure adjustment knob to reset. <br>7. Please use the pressure regulating knob correctly. Do not turn the pressure regulating knob to the end first, otherwise high pressure will cause the phenomenon of high pressure damage. <br>8. This product is suitable for the detection and maintenance of various types of pressure vessels, heating pipelines, home improvement pipelines, fire protection pipelines and fire protection sprinkler systems.

1, open the folding bucket, inject the media for 5-100 degrees C of clean water, and then turn on the power standby.<br>2, the inlet water pipe self-locking connector connected to the test pressure pump into the water base, the return pipe plug in the regulator valve out of the water outlet, and the inlet and back pipe into the barrel.<br>3, press the "start" switch, wait ingest the outlet has normal water flow out of the stop, tighten the pressure gauge under the copper discharge knob, and connect the water high-pressure pipe.<br>4, after the start to the pipe under test pressure, the pressure control valve on the red knob slowly screwed down, the pressure value of the table to reach the required pressure of the pipe (0-1.2MPA), lock hold pressure lock plate, stop the pressure.<br>5, after the shutdown of the pressure, observe whether the pressure value has decreased, such as the pressure value is lower than the required test value can be then start-up replenishment, after the replenishment, if there is still a pressure drop, to check the connections and the pipeline under test whether there is a leak.<br>6, after the test is completed, disconnect the power supply, open the discharge valve switch drain discharge pressure, and loosen the pressure control knob reset.<br>7, please use the control knob correctly, do not first turn the pressure knob to the end, otherwise high pressure will cause high-pressure loss of the meter phenomenon.<br>8, this product is suitable for all types of pressure vessels, heating pipes, home pipes and fire pipes and fire-fighting self-injection system detection and maintenance.

1. Open the folding bucket, inject 5-100 ℃ clean water, and then connect the power supply for standby.<br>2. Connect the self-locking joint of the water inlet pipe to the water inlet seat of the pressure test pump, insert the return pipe into the water outlet of the pressure regulating valve, and put the water inlet pipe and return pipe into the barrel.<br>3. Press the "start" switch, and stop the machine when there is normal water flowing out of the water outlet. Tighten the copper pressure relief knob under the pressure gauge, and connect the high-pressure pipe of the water outlet.<br>4. After starting the machine and pressurizing the pipeline under test, slowly screw down the red knob on the pressure regulating valve. When the pressure value of the gauge reaches the required pressure (0-1.2mpa) of the pipeline, lock the pressure retaining locking tab and stop the machine for pressure retaining.<br>5. After shutdown and pressure maintaining, observe whether the pressure value drops. If the pressure value is lower than the required test value, start up the machine for pressure compensation. If there is still pressure drop after pressure compensation, check whether there is leakage at each connection and the pipeline under test.<br>6. After the test, disconnect the power supply, turn on the relief valve switch to drain the water and relieve the pressure, and loosen the pressure regulating knob to reset.<br>7. Please use the pressure regulating knob correctly. Do not turn the knob to the end first, otherwise the high pressure will cause the phenomenon of high pressure loss.<br>8. This product is suitable for the inspection and maintenance of all kinds of pressure vessels, heating pipes, domestic pipes, fire pipes and fire sprinkler system.<br>
