When the high-pressure cleaner is running under high pressure, all the over-current parts are in high-pressure energy storage state from the high-pressure cylinder of the pump to the cleaning nozzle. The shock wave will inevitably damage the surrounding equipment in case of failure due to the rapid expansion of the fluid. And injuries. The water jet itself has a great destructive force, which is enough to damage any part of the human body, so it is very important to ensure the safety of cleaning operation. Of course, the water jet manufacturer is manufactured according to the relevant product standards and can ensure the safety of the device itself, but the potential safety hazards of users in the process of system installation must be avoided.
The danger and harmfulness of water spray of high pressure washer exist in equipment and operation. High pressure cleaning machine is the key to safe operation in cleaning operation.
The danger and harm of water jet in high pressure washing machine are in two aspects: equipment and operation. The key points of safety operation for high pressure washing machine in cleaning operation are as follows:
1. The operator must be trained to verify that he has the skills of installing, operating and repairing equipment, and wear labor protection articles in accordance with the operation safety specifications during operation.
2. The recoil force of the gun and nozzle operator shall not exceed 1/3 of its weight, and the design reverse force of the handheld gun or nozzle shall not be greater than 200N.
3. Under pressure condition, screw connection parts of any part of high pressure water system shall not be fastened, and all hose joints must be protected by flexible buckle.
4. The hose and nozzle assembly are cleaned in the pipeline. The nozzle enters by its backward jet. A rigid pipe of sufficient length must be set between the nozzle and the hose to prevent the nozzle from turning over in the pipe and hurting people.
