dosing device

Product description:

Complete dosing system is a new concept of chemical water treatment dosing device, already in the domestic and international power, male workers, municipal water treatment field such as extensive application. It is will metering pump, dissolve yuexiang, control system and pipe valve and all equipment, components installed in the same base platform, the realization of liquids, measuring dissolve worthy of a functional unit dosing overall combination, with compact structure, cover an area of an area small and easy to transport installation etc. Characteristics.

Application:
1, coal-fired power industry boiler water processing system, circulation cooling system, raw water pretreatment and wastewater treatment system;
2, petroleum, chemical industry furnace water treatment system, circulation cooling system, the chemical additive dosing system, wastewater treatment system;
3, municipal water supply, sewage treatment system;
4, and other related industries

2.Phosphate dosing device

Process principle:

In order to prevent produced in the boiler scale and alkaline corrosion, calcium phosphate, adding water in to make the water into the furnace with calcium ion won't form scale, but produce water residue, and through the boiler sewage shall be excluded. This to the boiler water dosing phosphate processing method called boiler water phosphate processing, in the oven, water with phosphate solution control a certain amount of phosphoric acid root, in alkaline conditions, produce the following response:

Ca10(OH)2(PO4)3-+2OH------Ca10(OH)2(PO4)6

Generated Ca10 (OH) 2 (PO4) 6 called alkali type calcium phosphate, is a kind of soft water boiler slag, very easy with emission and eliminate.

3.Installation operation caution and common troubleshooting methods

1, check the dosing device at the same level whether Israel platform online (don't be fitted with anchor bolts), pump liquid mouth have silk buckle connection head, fast connection, flange adapter, the corresponding pick good, connect the power connector.
2, good preparation before operation, metering pump body, deceleration conveying rate into the right amount of SBJ - 20 and SBJ - 30, with oil level JiXieYou horizontal shall prevail.

3, close the drain valve and pipe valves, manually or automatically according to the power of liquids, filling, electric control cabinet, power indicator says the power is connected. Press the button, the blender mixing tanks start work 3-5 minutes, open pipe valves, open flow control valves, press metering pump launch button, metering pump and began to work.
4, to regularly check whether metering pump feeding port of pipelines, filter jams, regular cleaning, jam in case.
5, regular check agitator, check whether flexible rotation, stirring shaft of impeller whether distortion, united side weeks whether loose sleeves, excessive, consume mixing power torque. Theory is broken it needs to be replaced immediately.

 6.Using two or more pump dosing pump should be used alternately, avoid long-term start or disable a pump.
