中文Rotary pump: The advantages of using rotary pumps compared to long axis submerged pumps
2020-10-09
Rotary pump. The transportation of oily wastewater and oily sludge is a common problem in the crude oil and petrochemical industry's transfer stations, storage tank areas, and sewage tanks. The composition is very complex and has serious erosion and wear. Choosing a long axis submersible pump can transfer the material to the road surface normally. However, in the long run, the weak points of unstable total flow rate, poor self suction capacity, and increased maintenance costs are reflected.
1. Due to the weak corrosion resistance of underwater installation, the electric motor and other components are prone to damage, and maintenance must be lifted onto the road surface. If the indoor space for maintenance is limited, combined with the damage caused by shutdown, the cost of comprehensive application is too high.
2. The total flow rate is unstable and the self suction capacity is poor. This process can be named as an oil content sewage lifting device according to its application. If the total flow rate cannot reach the required level and the self suction capacity is poor, the process regulations should not be followed. Later, the self suction centrifugal water pump was replaced, but the actual effect was not satisfactory.
Vulcanized rubber cam rotor pump is a type of capacity pump. Vulcanized rubber camshaft motor rotor is generally used with spiral motor rotor, fluorine rubber coating, acid and alkali resistance, corrosion resistance, and wear resistance. Because the gap between the motor rotor and the pump body is small, the pump itself has good self suction working ability.
The self suction type of vulcanized rubber cam rotor pump does not necessarily lead to a canal irrigation pump
The installation method is dry trial installation, which occupies a small area.
The maintenance method is to use online maintenance, and the pipeline and its motor do not need to be separated from the water pump impeller. Simply open the pump cover. A single person can perform disassembly and replacement work in 25 minutes.
The purchase cost of cam rotor pump is relatively low, but there is no need to replace spare parts within 2 years. On the other hand, the purchase price of long shaft submerged pump is cheap, but the actual application effect is not good, there are many common faults, the maintenance process is inconvenient, and the cost of maintenance is too high.
Therefore, with the development trend of branding and intelligent systems required for weapons and equipment, sulfurized rubber cam rotor pumps can be selected as a replacement for submerged pumps in oil containing wastewater lifting devices.
