Způsoby, jak ušetřit materiály při použití chemických čerpadel


1. Vylepšete proces údržby prochemické čerpadlo, snížit třecí kolizi a ztrátu víru mezi vodou a stěnou průtokového kanálu a vyleštit a vyleštit klíčové části, které mají větší dopad na účinnost. Lesk na kov je vidět leštěním a původní průtokový kanál nesmí být poškozen. Zadejte řádek.

2. Reduce the leakage loss in the chemické čerpadlo, improve the processing accuracy and assembly quality of the parts, reduce the radial clearance of the throttle sleeve in front of the balance disc and the radial clearance of the front and rear seal rings of the impeller and the guide vane seal ring, and reduce the liquid in the chemické čerpadlo Pressure energy loss caused by leakage from the high-pressure side to the low-pressure side. For the impeller sealing ring, guide vane sleeve, front throttling of the balance disc and other parts, materials with higher hardness should be selected, and heat treatment to improve wear resistance should be carried out.

3. When starting the chemické čerpadlo in cold state, the chemické čerpadlo should be fully warmed according to the requirements of the regulations. If the chemické čerpadlo is not warmed enough, a large thermal temperature difference between the upper and lower sides of the chemické čerpadlo is likely to occur, causing the rotor to be bow-shaped. It is easy to start the chemické čerpadlo at this time The internal sealing gap wears large, causing internal leakage and increased volume loss of reflux. When adjusting the load, it must be stable to avoid large fluctuations in feed water pressure, maintain continuous and stable operation of the chemické čerpadlo, and reduce the axial movement of the chemické čerpadlo to avoid wear of the seal gap.

4. Under normal operating conditions, the water discharge door, drain door and chemické čerpadlo body discharge door of the water supply system, the boiler's regular sewage discharge door, and the accident discharge door should be closed tightly, and the door should be cold after touching the inspection door. If the valve is not tight, it should be dealt with in time.

5. The recirculation device for the chemické čerpadlo is used to maintain a minimum flow for the chemické čerpadlo when it is started, just put into operation, and when the boiler water supply is stopped, so as to prevent the small flow and heat generation during operation and the vaporization of the water supply and cause accidents. The recirculation door should be closed tightly during normal operation.
