Circuit design of Yuhuan CDR-30A electric water heater

According to the water storage method, the electric water heater can be divided into three types: instant type, volume type and speed type. The volume type is the main form of electric water heater. According to different installation methods, it can be further divided into vertical, horizontal and floor type. According to the pressure or not, it can be divided into simple type and pressure type, and can be divided into large volume and small volume according to the volume.
The electric water heater generally needs a current of 20 or even 30 amps or more, that is, the heat is opened, the water temperature is constant, the heating efficiency is high, and the installation space is small. The high-quality instant electric water heater with internal low-pressure treatment can increase the shunt at the time of installation, and can supply water for multiple faucets. The higher-power products are installed in the bathroom, which can be used for showers, and can also be used for washing, general households. Use energy saving and environmental protection. According to the needs of the market, electric water heaters are further divided into shower and kitchen types. As shown in the figure, the circuit design of Yuhuan CDR-30A electric water heater.

Agricultural Machinery Accessories Parts

Agricultural machinery parts more generally summarizes the machinery parts associated with agricultural production, the coverage is very wide. Such as: tractor power mechanical parts, tires, bucket, etc., harvester including potato harvester, peanut harvester, agricultural machinery and tools (pear. Take the plough as an example, the plough includes the disc plough, moldshare plough, animal force plough, the component of the whole machine includes the plow tip, the plow leg, the plow share, the plow piece and so on. Related industries, the production of supporting products accessories can be called agricultural machinery accessories.

What are common agricultural machinery accessoriesNow rural use of agricultural machinery is common, in the job, because of farmland environment is bad, so most of farm machinery accessories used are consumables, need to change regularly, in order to avoid failure, farm machinery accessories usually used are:1, agricultural tiresQualified agricultural tires tues both sides have the trademark, model, specification, layer number and the cord material etc, and clear, eye-catching, some still carries with production and inspection chapter; Inner surface should be smooth with brightness, the hand has the elasticity. If the tyre surface identification is not complete or fuzzy, inner tube lacklustre, tire body thin and uneven thickness, hand inelastic, is defective.2, threadProduct appearance should be bright and clean without rust, without defects, continuous spiral arm, no burr, no crack. Will be specimen and standard accessories spinning together, should be able to spin to the terminal, and no card lag phenomenon in the process of precession; Spin after flipping the fittings should be without shaking and sound, and if the thread has defects such as corrosion, crack, burr, spin the move after fitting will shake, for inferiority of quality.3, the gearQualified gear packing should be in good condition, tooth surface should be smooth and no cutting marks, no burr, and coated with anti-rust oil or wax, gear profile usually have code, with a hacksaw blade broken crop row gear face, should be no scratches or only a fine scratches. If the gear surface have burr, notching, rust, sharp strokes with sawdust and Nick (insufficient hardness), the poor quality.4, V beltQualified V belt surface is smooth, seamless joint glue, outside the circle on a clear trademark, specification, manufacturer name and logo, the length of the same type of V belt should be consistent.If the V belt look rough, uneven glue joint or openings, shade thrum exposed edges, no marks or blur, the V belt length is differ, it is false and inferior product.5, V belt wheelQualified V belt wheel surface porosity, crack, grooved smooth, V belt buckle grooved, V belt is slightly higher than that of slot and the bottom of the V belt is not drain contact. If discover wheel blowhole defects such as trough, the groove surface shape and qualified V belt do not form a complete set, it is bad.
