In the blink of an eye to the big cold, this winter is particularly long and cold. In winter, the maintenance of high-pressure water equipment is very important, if the equipment is not maintained in place, the temperature reaching the freezing point may cause serious damage to the equipment. The packing box may also freeze due to water retention, resulting in damage to the packing box, combination valve, plunger, and valve block.
In order to prevent the system from freezing, it is necessary to drain all the pipes, the booster pump and the water tank, and add antifreeze liquid to the stuffing box. If the equipment will be idle in winter, then the following steps of the plunger pump and pipeline antifreeze maintenance measures.
Equipment winter maintenance procedures
1. Drain the water tank
2. Disconnect the water supply pipe and high pressure drainage pipe connected to the hydraulic end valve block.
3, the hydraulic end valve block to empty the water, and then close the drain.
4. Connect a funnel device at the pipe connector.
5, the funnel device is installed in the hydraulic end of the valve block into the water end.
6. Pour glycol antifreeze into the funnel. Total pour about 0.5 gallons (2 L).
7. Adjust the reset switch to the ON position and turn off the state with the bypass low water level.
8. Before restarting the engine, check the drain end connector of the hydraulic end valve block to ensure that this end is smooth. The antifreeze is discharged from this end.
9. Start the engine.
10, gently flick the clutch, boot direction gently pressure. Observe the plunger moving back and forth and the antifreeze slowly discharging from the end of the valve block.
11. After the antifreeze is drained from the drainage end, turn off the clutch and shut down the engine.
12. Remove the funnel at the water inlet and reconnect the water inlet pipe.
13. Cut off the water lubrication pipe from the stuffing box and drain the pipe.
14, (for equipment equipped with additional pumps) disconnect the drainage pipe on the booster pump, drain the water in the pipeline, and then reconnect the pipeline.
15. Flush the antifreeze through the system.
16, ensure that the water supply pipeline can also be subject to anti-freezing treatment.
