Maintenance method of metering pump
There are three components of a metering pump mainly power drive, fluid delivery and regulation control. The power drive device drives the fluid delivery diaphragm to achieve reciprocating motion via a mechanical linkage system. Classification of metering pumps: According to the flow part, metering pumps can be divided into plunger piston type, mechanical diaphragm type, and hydraulic diaphragm type; according to the driving mode, it can be divided into motor drive, electromagnetic drive, and pneumatic; according to the working mode, it can be divided into Reciprocating, rotary, gear type. Currently, metering pumps are mainly divided into two types: plunger type and diaphragm type due to their different power drive and fluid delivery methods. Components of a metering pump and classification will play a great role.
Overhaul of metering pump (take mechanical diaphragm metering pump as an example). Due to its high heat dissipation performance and light overall weight, it is suitable for various acid and alkali liquids, non-toxic and tasteless; there is no leakage on the whole, and can be placed on a medicine tank or pipeline; the contact medium pump head is made of PVC, PTFE and stainless steel; High, generally applicable to the water treatment industry with low pressure requirements; when the pump is running or stopped, the flow can be adjusted arbitrarily and the output can be quantitative. It is precisely because the metering pump is a relatively sophisticated device. In the process of adding chemicals, impurities and particles often enter the pump body or other factors cause the metering pump to fail to work normally, so it is necessary to check the Overhaul of metering pump frequently.
Before performing maintenance, we must first determine what caused the fault based on Condition of metering pump and Components of a metering pump. Carry out maintenance according to the content of the fault. The general maintenance steps are as follows: (1) Turn off the power, check the seal of the mechanical part, and see if there is any leakage of liquid medicine in the pump body; (2) Close the valve at the inlet and outlet of the pump body, and check whether there is any damage on site Factors of maintenance; (3) Disassemble the pump body; (4) Perform corresponding maintenance according to the fault; for example, the most common fault in daily operation is the blockage of the suction pipe, first clean the one-way valve, clean up the impurities in the pipeline, and then Remove the check valve assembly, clean it with clean ethanol or gasoline, and scrub with a brush; do not touch the blade and flat surface of the valve seat with hard objects (such as tweezers, etc.), and do not damage the valve ball to avoid accuracy Affected or unable to inhale liquid medicine. (5) Be very careful when installing. The removed parts must be installed in strict accordance with the original position, especially the direction. After installation, tighten the bolts. The tightening bolts must be synchronized and gradual, and not tightened too tightly. , So as to avoid damage to the equipment or leakage.
Solve the problem that operators do not have time for maintenance. In the production process of water treatment, how to deal with the relationship between operation, maintenance and operation personnel. Although each operation has its own different job responsibilities, and the work schedule is relatively full, if there is equipment that needs to be overhauled and maintained, the operating personnel must cooperate and assist each other, so that some operating personnel can have time to deal with it. The equipment is overhauled. Overhaul of metering pumps need to cooperate with each other to achieve the best.
Depending on the Condition of metering pump, simple mechanical knowledge training is required for operators. While training the mechanical knowledge, it is necessary to train the Overhaul of metering pump and maintenance content for the operating personnel. People who do not understand mechanical knowledge often make such mistakes: when disassembling the equipment, the parts are placed everywhere, without classification, when the parts are not found or the parts are not numbered during the installation, and when the bolts are tightened, Failure to follow the principle of gradual and orderly approach can easily damage the equipment. Operators not only manage the operation but also part of the equipment, so that they can understand the knowledge of the operation, have the ability to understand the equipment, broaden their horizons, exercise the operators, and continuously improve their own quality, which is conducive to the personal career development of the operators. And planning.
