Oil Pumps-High Temperature Oil Pump Selection Note
Group Details
Détails |
The high temperature oil pump is an ideal hot oil circulation pump or a heat carrier transfer pump, and is an ideal matching pump for heat exchange equipment. The heat oil pump has a reasonable structure, excellent performance and reliable use. Suitable for conveying high temperature liquids without solid particles. So what are the selection methods for high temperature oil pumps? First, the lift required by the device system is another important performance data of pump selection. Generally, the lift is selected by 5% -10% of the margin. Second, liquid properties, including the name of the liquid medium, physical properties, chemical properties and other properties, physical properties include temperature c density d, viscosity u, solid particle diameter and gas content in the medium, etc. This involves the system head, effective gas Erosion calculation and suitable pump types: Chemical properties, mainly refers to the chemical corrosivity and toxicity of liquid media, are the important basis for selecting high-temperature heat-conducting oil pump materials and which type of shaft seal. 3. Flow is one of the important performance data of the selected heat transfer oil pump, which directly affects the production capacity and conveying capacity of the entire device. For example, the normal, minimum, and maximum flow rates of the pump can be calculated in the process design of the Design Institute. When selecting a pump, take the maximum flow as the basis and take into account the normal flow. When there is no maximum flow, usually 1.1 times the normal flow can be taken as the maximum flow. Fourth, there are many operating conditions, such as liquid operation T saturated steam force P, suction side pressure PS (absolute), discharge side container pressure PZ, altitude, ambient temperature operation is gap or continuous, high temperature heat transfer oil pump position Whether it is fixed or removable. Fifth, the pipeline layout conditions of the device system refer to the liquid delivery height, the liquid delivery distance, and the liquid delivery direction. Some data such as the minimum liquid level on the suction side and the maximum liquid level on the discharge side and the pipe specifications and their lengths, materials, and pipe specifications Etc. in order to perform system head calculation and check of cavitation allowance. The Oil Pumps works by circulating oil under pressure to the engine's rotating bearings, sliding pistons and camshafts. Large-capacity fluid bearings can be used to help cool the engine.
