Pump industry suppliers to tell you: self-priming pump maintenance should be paid attention to when several main parts

general maintenance self-priming pump should pay attention to a few main parts:

1, the rolling bearing: after the long run, bearing wear to a certain extent, must be replaced.

2 before and after sealing ring, sealing ring: when the ring is worn to a certain degree, must be replaced.

3, mechanical seal, mechanical seal in the case of no leakage, generally should not open it to check. If the lower bearing body leak mouth have serious leakage, overhauling should be made for mechanical seal. Mechanical seal installation, it must be light, the only, pay attention to cooperate with the clean, protect the static ring and the ring of the mirror, it is forbidden to tap on a collision. Due to mechanical seal leakage reason mainly is the hair by friction pair mirror. The repair method: can be recovery of friction pair end face grinding to a mirror. Leakage of mechanical seal products, another is caused by the improper o-ring installed, or become aging may go. At this time will be expected to replace the o-ring to reassemble.

self-priming pump has the advantage of how

self-priming sewage pump is a common type of self-priming pump, can the so-called sewage pump use, because it has both the function of self-priming pump, use more convenient than other pump type, and the pump has excellent properties such as corrosion resistant, corrosion resistant self-priming pump is a veritable. So, in the urban sewage or other special widely applied in wastewater treatment.

1, blowdown ability: special impeller block design, ensure the pump efficiency and no blockage.

2, high efficiency and energy saving: with excellent hydraulic model, the efficiency is higher than general self-priming pump 3 ~ 5%.

3, good self-priming performance, higher than average self-priming pump self-priming height 1 meter, and with a shorter time.

so the ZW self-priming sewage pump is a kind of ZW type self-priming non-clog sewage pump, very suitable for chemical, petroleum, pharmaceutical, mining, paper, fiber, pulp, textile, food, power plants and municipal drainage project, public facilities, sewage, digging of aquaculture and other industries.

pump industry suppliers is the collection scientific research, design, production, management, services for the integration of production enterprises, the products are widely used in petroleum, chemical industry, metallurgy, electric power, mining, coking, medicine, printing and dyeing, food, paper making, environmental protection and other fields. The company has a modern pump performance testing means, equipment is excellent. Main production ZA self-priming pump, ZAO, ZE petrochemical pump, CZ chemical process pump, IH chemical centrifugal pump, forced circulation water pump, SPP chemical mixed-flow pump of 28 kinds of material, 30 series more than 1000 specifications special alloy chemical pumps, valves, stainless steel pipe, fluorine pipe parts.
