Titanium alloy centrifugal pump about how to choose the smooth oil

titanium alloy centrifugal pump sliding bearing smooth method and smooth oil pick

titanium alloy centrifugal pump is commonly used for liquid transport equipment in the chemical industry, the titanium alloy centrifugal water pump type many, different using requirements, smooth way what about titanium alloy centrifugal pump bearing, smooth oil selection criteria?

choose smooth oil general guidelines

1, should choose smooth oil of high viscosity high work temperature. Temperature is too high to use carbon small smooth oil of high flash point, the temperature is too low to choose the smooth oil with low freezing point.

2, processing roughness or worn appearance smooth oil of high viscosity should be chosen.

4, low-speed overloading, the impact of variable load operation under the condition of using smooth oil of high viscosity, high speed light load is smooth selection of low viscosity oil, reducing conflict lost.

smooth way of titanium alloy centrifugal pump sliding bearing

1, the drops of oil slick: roughly from the container through hole and valve supply quantitative smooth oil, classic is drip oil cup. Smooth drops of oil varies with oil viscosity and bearing clearance and oil hole position differs significantly change.

2, manual smooth: lack of smooth oil bearing was found, in season with oiler oil supply, it is the original way, this way is difficult to maintain a certain oil and set on the oil-way dust cover or ball valve, and felt, wool and other filtration equipment.

4, pressure oil supply smooth: by smooth and the pressure of the pump to the bearing oil, smooth oil recovery will be flowed from bearing into the oil pool to use again, is the number of oil, and safe way to smooth, suitable for high speed sliding bearing.

titanium alloy centrifugal pump instrument fault reason and treatment method of

titanium alloy centrifugal pump is now a common pump used in chemical industry, the type of titanium alloy centrifugal pump also many, generally speaking, there are vertical and horizontal two forms, the instrument fault reasons of the problem of how to deal with? Below according to the analysis of a fault reason:

1, the liquid level detection problem: level indicator is not normal, high or low, or not to change

view: float level gauge zero and range; Float liquid level gauge pressure valve is blocked, at the top of the exhaust valve leakage.

2, traffic detection problem: flow indicator is not normal, high or low, or change slowly or not.

view: traffic actual condition deviates from the planning conditions is very big, the titanium alloy centrifugal pump outlet pressure instability, process gas liquid two phase medium, process piping with jam phenomenon, formation of local vortex.

3, temperature detection problem: temperature indication is not normal, high or low, or change slowly or not.

view: thermocouple, thermal resistance box is water, if there is a short circuit, terminal titanium alloy centrifugal pump corrosion, temperature safety barrier is out of order, no output or output is not correct.
