To express in writing, you can add appropriate pictures (composition form, preferably 600 or more, not enough, OK, I put together a bit, will give points!) What kind of person would you help me with?
The main flow of water pump (take centrifugal pump as an example):Technical determination of Drawing > raw material storage > mold preparation > casting moulding > machining > parts experiment > Assembly > performance experiment > painting packing > storage.Here are a few key steps:1) the technique determines the graphMainly the work of designers. Generally according to the parameters of the pump (flow, lift, cavitation, efficiency, etc.) to determine the specific speed of pumps, impeller form, impeller size, impeller material, pump body, pump shaft and so on. One of the most important thing is to draw the impeller woodenpatterns.2) die preparationThe mold is mainly composed of workers according to the water pump impeller woodenpatterns production model.3) casting moldingThe casting molding sand is made on the base of the mould.4) machiningWater pump parts processing, because it has hydraulic flow channel, in considering the positioning clamping standard, must find the correct flow channel of the correct position. Avoid assembly, resulting in water pressure chamber and impeller flow channel skew, dislocation, uneven gap, or even rub, affecting product quality. In order to ensure the accuracy of parts manufacturing, it is necessary to design the appropriate tooling, and reasonable arrangements for technological processes, control process factors.
The selection of water culture equipment: processing and improvement of mineral water bottles, coke bottles, plastic barrels, glass bottles and so on. Design and manufacture of pipeline circulation device;From the hydroponics: root washing water method, interpolation method, clipping rhizome plant method, cutting method of tiller buds;The disinfection of plant roots or wound: 0.05 - 0.1% of the Potassium Permanganate solution soak for 10 minutes;Scientific cultivation: rooting and domestication, bottling and maintenanceB, a general management method for hydroponic plants:The root of the reasonable fertilization for washing the water to wash the leaves and proper ventilation timely pruning maintains health2, cultivars and quantities:A, selection of cultivated species: Based on the adaptability of plants to local environmental temperatureThe main products: green, Chlorophytum, iris, reineckea and other 5 - 8 pots, used to decorate the classroom office.Product development: Canna, jiupinglan, geranium leaves, Jasper, Calla, life Rong, money tree, pocket coconut, Schefflera, lotus and other stone 1 - 2 pots.B, the source of seedlings:(1) encourage students to actively participate in and prepare for saplings, such as iris, reineckea, Canna.(2) the market to buy a part, such as: Scindapsus, Chlorophytum, jiupinglan, geranium leaves, Jasper, Calla, life Rong, money tree, pocket coconut.
You should go to the water pump factory visit, than to a vivid books. General settings are specific parameters - three view - model making - modification - Roughing - semi finishing - finishing - material quenching - heat treatment - carburizing - Black - assembly - spray painting - Inspection - Labelling - packaging.
