What is the difference between a hydrostatic pump and a hydraulic pump?

The Main Difference Between A Static Hydraulic Pump And A Hydraulic Pump Lies In Their Working State And Application Scenarios

Working Condition

1‌. Static hydraulic pump: In a static hydraulic system, the liquid is in a stable static state, and energy conversion occurs in a static state. In this state, the operating speed of hydraulic components is slow and the noise generated is extremely low.

2. Hydraulic pump: In the power hydraulic system, the liquid is in a dynamic state, the liquid flow speed is fast, and the noise generated is relatively high.

Application scenarios

1. Hydrostatic pump: Suitable for applications that require low noise and high precision, such as precision instruments, laboratory equipment, etc. Due to its low noise and high precision, static hydraulic pumps are widely used in various fields such as metallurgy, aviation, railway, engineering machinery, and automobiles

2. Hydraulic pump: suitable for general industrial applications, such as engineering machinery, metallurgy, papermaking, petroleum and other fields. Power hydraulic pumps exhibit high efficiency and applicability in these fields

Comparison of advantages and disadvantages

Hydrostatic pump:

Advantages: Low noise, high precision, suitable for situations that require precise control.

Disadvantage: The power output is relatively low, making it suitable for situations with static or low dynamic requirements.

Hydraulic pump:

Advantages: High power output, suitable for high dynamic demand scenarios.

Disadvantages: High noise and relatively low accuracy

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
