Daily maintenance and troubleshooting strategies for water hammer pulse testing machine

　　Water hammer pulse testing machineIt is a professional testing equipment used to simulate transient pressure changes (such as water hammer effect) in pipeline systems, widely used for pressure resistance testing of valves, pipes, hydraulic components and other products. In order to ensure its long-term stable operation and obtain accurate and reliable test data, it is necessary to carry out scientific and reasonable daily maintenance of the equipment and master the troubleshooting methods for common faults.

1、 Daily maintenance strategy

1. Regularly clean the surface and internal components of the equipment

Keep the appearance of the equipment clean and prevent dust from entering the control system; Regularly clean impurities in hydraulic cylinders, sensors, and connecting pipelines to avoid blockages or wear that may affect testing accuracy.

2. Check the status of the hydraulic system

Regularly observe whether the hydraulic oil level is normal, whether the oil quality has deteriorated or emulsified, and replace it in a timely manner if necessary; Check for any leakage at each joint to ensure good sealing of the hydraulic system.

3. Verify key components

Key components such as pressure sensors and pulse generators should be calibrated according to the manufacturer's recommended cycle to ensure the accuracy of test data.

4. Lubricate moving parts

For components with sliding or rotating structures, such as guide rails, screws, etc., lubricating oil or grease should be regularly applied to reduce friction loss and extend service life.

5. Electrical system inspection

Regularly check whether the wiring connections inside the control cabinet are secure, and whether the relays, PLC modules, and other components are working properly to prevent misoperation or shutdown caused by electrical faults.

2、 Common faults and troubleshooting methods

1. The pressure cannot rise or fluctuates greatly

Possible reasons: Insufficient supply pressure of hydraulic pump, improper setting of relief valve, blocked oil circuit or damaged sensor.

Solution: Check the operating status of the hydraulic pump, adjust or replace the relief valve, clean the oil circuit, and verify or replace the sensor.

2. Unstable pulse frequency

Possible reasons: incorrect control system parameter settings, unstable gas or power supply voltage.

Solution: Reset the control parameters and use a regulated power supply or gas source adjustment device.

3. The equipment operates with loud noise

Possible reasons: Hydraulic system intake, bearing wear, or loose fasteners.

Solution: Exhaust treatment, replace worn parts, and tighten all connection parts.

4. The touch screen has no display or operation failure

Possible reasons: power failure, poor contact of communication cables, or damage to the touch screen.

Solution: Check the power supply status, unplug the communication cable, and replace the screen if necessary.

Good daily maintenance can not only prolongWater hammer pulse testing machineThe service life can also effectively improve the accuracy and repeatability of test results. Meanwhile, establishing a rapid response mechanism for common faults can help improve the operational efficiency of equipment and ensure the smooth progress of product quality inspection work. For operators, familiarity with equipment structure and basic maintenance skills is also an important guarantee for ensuring efficient operation of equipment.
