Can the flow rate of a magnetic centrifugal pump be adjusted? Many people want to know this question. In the process of selection, there will inevitably be improper selection resulting in a large or small error in the flow rate. Directly without an economic loss will be very large, with and can not use, this situation should be how to do? Do not be too anxious, the flow rate of magnetic centrifugal pumps can be adjusted, the following teach you the operation.
General situation magnetic centrifugal pump model may be matched with a large, or their own process required flow is small, there is no suitable model can meet the need to adjust the flow, which is a lot of practical magnetic pump users often encounter problems, but many users do not know much about the use of a magnetic centrifugal pump, misuse of the situation more, resulting in a decline in the service life of the pump or simply damaged. Whether magnetic pump or centrifugal pump, flow and head design are certain standards, parameters, in general, cannot be adjusted at will, but today we will tell you how to adjust and then operate to ensure the normal operation of magnetic centrifugal pump.
The bypass pipeline is used to connect the discharge pipeline with the suction pipeline so that the discharged liquid partially flows back to the suction pipeline for flow adjustment. There is a bypass adjustment valve in the bypass line, which can be used to simply adjust the amount of return flow to achieve the purpose of flow regulation. This regulation method has power consumption loss, so the economy is poor.
For magnetic centrifugal pump can use a tower wheel or gearbox to change the pump shaft speed, so that the number of piston reciprocation changes. But it should be noted that when the speed becomes large, the power of the prime mover, the strength of the pump parts, and the limit speed should meet the requirements. For the direct action of steam reciprocating pump, as long as the control into the steam valve opening can change the piston stroke, so as to adjust the flow of the corrosion-resistant magnetic pump.
The common method is to change the piston stroke by changing the position of the crankpin, adjusting the clearance between the plunger and the crosshead connection, or using a piston stroke adjustment mechanism. The piston stroke adjustment mechanism can be steplessly adjusted, and the stroke can be adjusted to zero so that the flow of the acid and alkali resistant magnetic pump can be adjusted arbitrarily between the two.
The above three methods can adjust the flow of the magnetic centrifugal pump, whether it is used now or not, do a good job of knowledge reserve, in the event of a similar situation will not be overwhelmed.
Taicang magnetic pump Co., Ltd. was born in 1979. It cooperated with Shanghai Chemical Design Institute to form a unique core research project with magnetic drive pump, and achieved great success. It has become the professional company in China to comprehensively design and produce magnetic drive pump. Today, Taicang magnetic pump Co., Ltd. has become a leading manufacturer of magnetic drive pumps in China, with many patents and 12 utility model patents.
