价格由什么来进行决定的?

气液增压泵由恒流电源供电,以减少环境温度的影响。当压力变化时,由于桥臂电阻值的变化,输出电压也随之变化。差分化放大器经过放大转换后,将输出电压转换为相应的电流信号。通过非线性整流回路对电流进行补偿后,将输入压力信号生成近似线性关系的直流4-20ma标准输出信号。
The gas-liquid booster pump is powered by constant current power supply to reduce the influence of ambient temperature. When the pressure changes, due to the change of bridge arm resistance value, the output voltage of gas-liquid booster pump also changes. After amplification and conversion, the differential amplifier converts the output voltage into the corresponding current signal. After the current is compensated by the nonlinear rectifier circuit, the input pressure signal is generated into a standard DC 4-20mA output signal with approximately linear relationship.
一、缸径、行程;是大家可以直观的看出气液增压泵的体积大小,一般缸径越大的情况下,气液泵的价格就会越高,缸径、行程大的增压泵他的输出流量较大,也很好的决定了泵的稳定性,但是泵的缸径是取决于客户对现场使用工况的要求;
1、 Cylinder diameter and stroke: you can intuitively see the volume of the gas-liquid booster pump. Generally, the larger the cylinder diameter is, the higher the price of the gas-liquid pump will be. The output flow of the booster pump with large cylinder diameter and stroke is larger, which also determines the stability of the pump, but the cylinder diameter of the pump depends on the customer's requirements for on-site operating conditions;
二、另外一个决定性因素是气液增压泵的增压比。增压比越高的情况下,压力输出就越大,对密封圈及材质的要求因素就更加严格,客户选择气液泵的时候一定要注意对泵的输出压力的需求,选型要留有余量,切不可过大,或者偏小;
2、 Another decisive factor is the pressure ratio of gas-liquid booster pump. The higher the pressure ratio is, the greater the pressure output will be, and the requirements for sealing ring and material will be more stringent. When customers choose gas-liquid pump, they must pay attention to the demand for the output pressure of the pump, and the type selection should leave a margin, which must not be too large or too small;
三、由于被增压介质的特殊性(腐蚀性、稠粘度等等)的制约,需要特殊定制,基础这种情况,需要投入的人工、成本就较大,那么气液泵的价格就会偏高。一般就以非标定做的价格进行报价;
3、 Some gas-liquid booster pumps need special customization due to the particularity of the pressurized medium (corrosiveness, viscosity, etc.). In this case, the labor and cost will be large, so the price of gas-liquid pump will be on the high side. Generally, the quotation is based on the non-standard price;
