Antique Bronze Bathroom Faucet
Antique Bathroom Faucet
Oil rubbed bronze Bathroom Faucet is one kind of antique bathroom faucets, which is a beautiful finished metal used for many home fixtures and hardware. Its nature as a [living finish",
so it is susceptible to some natural change and wear over time, including hard water spots if the fixture is exposed to moisture. Often clean and care for oil rubbed bronze bathroom
faucets with right method to keep it looking good for generations.

(1) Pre-start preparation a. Check the name, model, main performance and filling number of the lubricating oil before starting whether the requirements of technical documents are met; whether the bearing lubrication system, sealing system and cooling system are intact, Whether the waterway is smooth; circling the pump rotor 1 ~ 2 turn, check the rotor for friction or stuck phenomenon; in the vicinity of the coupling or belt guard, etc., whether there is interference with rotation of debris; pumps, housings, motors Of the foundation anchor bolts are loose; pump working system valves or ancillary devices should be in the pump load minimum position, the outlet valve should be closed; point pump to see whether the impeller steering steering with the design, if inconsistent, Impeller must be completely stopped turning, adjust the motor wiring, before starting again. b. Filling the water pump Prior to start-up, the pump housing and suction pipe must be filled with water, because of the presence of air, the suction port vacuum can not be formed and maintained. c. Warm pumps Pumps that deliver hot liquids, such as boiler feed pumps in power plants, must be warmed up before starting. This is because when the feed water pump is started, the high-temperature feed water flows through the pump, causing the temperature of the pump body to rise quickly from room temperature to 100-200 ° C, which causes the temperature difference between the inside and outside of the pump and between the components. If there is not enough Heat transfer time and appropriate measures to control the temperature rise will cause uneven expansion of the pump around, resulting in deformation of the various parts of the pump, wear, vibration and axle suspension accidents. (2) Start the program Centrifugal pump pump cavity and suction pipe all filled with water and no air, the outlet pump is closed. Pump to warm the pump is completed. For forced lubrication of the pump, start the oil pump to the bearings. Start the cooling water pump or turn on the cooling water valve. Closing start, pump idle time after starting does not allow more than 2 ~ 4min, the speed reaches the rated value, and gradually open the outlet valve of the centrifugal pump to increase the flow and achieve the required load. (3) Precautions in operation Pump manufacturers have provisions on the temperature of the bearing Rolling temperature rise is generally not more than 40 ℃, the surface temperature does not exceed 70 ℃, otherwise it shows the rolling bearing internal problems, stop checking. If it continues to run, it may cause an accident. For the temperature regulation of plain bearings, reference should be made to the technical documentation of the pump in the same way as rolling bearings.
