Heat conduction oil pump selection considerations and the cause of the time? _

matters needing attention in the selection of heat conduction oil pump

heat conduction oil pump, magnetic pump, acceptance of self heating radiator layout, changed the traditional water cooling layout, the layout is simple, small volume, saves the operation capability, good performance, the use of reliable, is China's digest absorb WaiYang pump developed on the base of the second generation product, the pump inlet is axial suction, exports to the middle vertical, with motor mounted on the base.

heat conduction oil pump selection basis, should be the credential process, water supply and drainage requirements, from five aspects to consider, both liquid transport quantity, unit head, temper, pipeline deployment and manipulation of the operating conditions, etc.

a, the required lift device system is another important performance data, selection of heat conduction oil pump usually takes zoom - 5% Head to selection after 10% allowance.

2, fluid properties, mainly refers to the name of the liquid medium, physical properties, chemical properties and other properties, physical properties with temperature c d density, viscosity, u, medium content of solid particles diameter harmonious body, etc. , which involves the system of the head, with gas corrosion allowance calculations and comply with the example of pump: chemical characteristics, important refers to the chemistry corrupt and toxicity of liquid medium, is to choose material of high temperature heat conduction oil pump and choose the kind of shaft seal type of important basis.

three, flow is one of the important performance data of heat conduction oil pump, it directly affects the entire plant production ability and the transport ability. If a court process the scheme can calculate normal, minimum, maximum three flow pump. Choosing a pump, based on maximum flow, double normal traffic, when there is no maximum flow, 1 is usually desirable to normal flow. 1 times as the maximum flow.

4, manipulating the contents of many conditions, such as liquid control T p, suction side pressure saturated steam force PS ( Absolute) , crowd out side pressure container PZ, altitude, temperature control is gap remains the same in a row, the location of the high temperature heat conduction oil pump is the firm continues to move.

5, device system pipeline deployment condition refers to send liquid height conveying fluid between liquid, such as absorption side the lowest level, crowd out side the highest level and some other data length, material, pipe fittings and pipe specifications and number of specifications, etc, in order to hold the comb head calculation and checking of NPSH.

the cause of the heat conduction oil pump fit?

there are two main types of result in hot oil pump fit condition, the cavitation in the composition of time and gas leaking time.

at the time of cavitation conditions, as long as the transport medium pressure in the operating temperature is lower than the saturated vapor pressure, the will, a time, and all is not a vacuum. A typical such as light hydrocarbon water pump seal fit.

in the gas leaking time conditions, consisting of gas leaking basically has the following several paths: one is the internal gas into the centrifugal heat pump, such as collection of pyrolysis gas inside the pipeline, etc. ; Another kind is outside air into the centrifugal heat pump, mainly is the relief system, air pump and the pipe flange or gland into the pump; Under this situation, a possible negative pressure inside the pump. But in fact, even a negative pressure, the exterior differential pressure of the pump would not exceed 1 kg/cm2 ( Trunnion for Φ 45 ~ 70 mm) , considering the time, the atmospheric pressure may effect on the projection area for static ring, but after the specific accounting, exterior differential pressure could not be greater than the spring push the sealing surface.
