Time: May 12, 2020 15:48 source: unknown author: Guangyuan cleaning equipment

Use High pressure cleaning machine Before operation, it is necessary to strictly follow the operation process on the instructions to ensure correct operation.
1、 Basic operation process
1. Press the start button, rotate for a while, and then press the stop button; check whether the rotation direction of the motor is consistent with the direction indicated on the coupling; if it is consistent, it can continue to operate; if the rotation direction is opposite to the direction indicated by the coupling, change the wiring positions of any two live wires of the cable, and ensure that the rotation direction is consistent;
2. Press the start button, and the machine will make a sound four or five seconds later; after hearing the sound, it will indicate the water gun holder to hold the gun handle and start to adjust the pressure; while adjusting, observe the pressure gauge; adjust the pressure to the required pressure and stop the adjustment; lock the pressure regulating valve; start the normal operation of the equipment;
3. Observe the water level of water tank at any time during operation, and supply water timely;
4. If there is a pause in the middle, just release the handle of the water gun without adjusting the pressure regulating valve; when cleaning again, hold the handle tightly to continue the operation;

2、 Faults and maintenance methods
1. The high pressure cleaning machine is noisy and has impact sound
Maintenance methods: remove the plunger locking screw, tighten the screw sleeve and then fix the locking screw; replace the bearing bush; if there is foreign matter in the plunger pump, stop the machine to check and remove the foreign matter.
2. The temperature of high-pressure cleaning cabinet is too high
Maintenance method: first of all, check whether the lubricating oil of the equipment is too much, too little or too dirty; the second is to replace the new oil.
3. The spray gun of high-pressure cleaning machine does not spray water
Maintenance method: the first reason is that the nozzle is blocked; the second reason is that the water inlet and filter are blocked.
1. The outlet pressure of washing machine is insufficient
Maintenance methods: the first reason is the aging of the relief valve; the second is the leakage of the high-pressure water seal and inlet and outlet single valve; the third reason is the internal failure of the high-pressure pump, wear of vulnerable parts, and blockage in the pipeline. The maintenance method for the above reasons is to replace the accessories; the fourth reason is that the nozzle aperture wear becomes larger, so the nozzle needs to be replaced.
2. The cleaning effect is not ideal
New purchase High pressure cleaning machine The reason for the unsatisfactory effect of cleaning equipment under good performance is that the selection of equipment is not appropriate. For example, 350 kg pressure equipment can only clean general soft scale, 500-700 kg pressure can clean hard scale, 700-1400 kg pressure can clean hard scale, 1400-2000 kg pressure can clean alumina scale, etc.
