What do you know about the pressure gauge set?

Publish Time: 2023-05-01     Origin: Site

pressure gauge set refers to an instrument that uses elastic elements as sensitive elements to measure and display a higher pressure than the ambient pressure. It is widely used and covers almost all industrial processes and scientific research fields.It can be used anywhere in the fields of heat pipe network, oil and gas transportation, water supply and gas supply, vehicle maintenance and repair workshops, etc. are used.

What are the main structures of the pressure gauge set?

Overflow Hole: In an emergency where the tube spring bursts, the internal pressure is discharged through the overflow hole outwards to prevent the glass pane from bursting. Note: To maintain the normal performance of the overflow hole, a distance of at least 10mm should be reserved behind the table, and the overflow hole must not be modified or closed.

Hands: In addition to standard hands, other hands are optional.

Glass pane: In addition to standard glass, other special glass materials such as tempered glass and non-reflective glass are optional.

Performance classification: ordinary type (standard), ordinary type for steam (M), heat resistant type (H), vibration resistant type (V), vibration resistant type for steam (MV), heat resistant and vibration resistant type (HV).

Treatment method: Oil-free and waterproof treatment Remove the water or oil remaining in the wetted part during manufacture.

Description of the exterior: In addition to the standard color, the shell color should be specified.

Throttle valve (optional): A throttle valve is installed at the pressure input to reduce pulsating pressures.


What do I need to pay attention to when using the pressure gauge set?

1.The meter must be vertical: use a 17-mm wrench to tighten it during installation, and the housing should not be twisted; Collisions should be avoided during transport;

2.The instrument should be used at an ambient temperature of -25~55℃;

3.The vibration frequency of the working environment is less than 25 Hz and the amplitude no more than 1 mm.

4.If the indicator value of the instrument does not return to zero during use due to the high ambient temperature, or the indicator value is outside the tolerance, the sealing rubber plug on the upper part of the housing can be cut off to prevent this from happening, interior of the instrument communicating with the atmosphere.


What measuring range does the pressure gauge set have?

The pressure gauge set is divided into vacuum meters, pressure vacuum meters, micromanometers, low pressure manometers, medium pressure manometers and high pressure manometers depending on the measuring range. Vacuum meters are used to measure pressure values smaller than atmospheric pressure; Overpressure vacuum meters are used to measure pressure values smaller and greater than atmospheric pressure; Micromanometers are used to measure pressure values below 60000 Pa; Low pressure gauges are used to measure pressure values of 0 to 6 MPa; Medium pressure gauges are used to measure the pressure value of 10.60 MPa.

    What is a gear pump?

    ​The gear pump consists of two gears, the pump body and the front and rear covers to form two enclosed spaces. As the gears rotate, the volume of space on the side of the gear displacement increases from small to large, creating a vacuum to suck in the liquid, and the volume of space on the side of the gear engagement increases the larger it becomes smaller, and the liquid is pushed into the pipeline. The intake cavity and the ejection cavity are separated by the engagement line of the two gears. The pressure at the output of the gear pump depends solely on the resistance at the pump output.

    What do you know about the use of gear pumps?

    ​The gear pump is simple and compact in construction, small, light, good in manufacturability, cheap in price, strong in self-priming, insensitive to oil pollution, large in speed range, able to withstand shock loads, convenient in maintenance and reliable in operation. The gear pump is a rotary pump that depends on the change and movement of the work volume formed between the pump cylinder and the combing gear to transport liquid or put pressure on it.

    How to select a control valve?

    ​The control valve consists of two main assemblies: valve body assembly and actuator assembly (or actuator system), which are divided into four series: single seat series regulating valve, double seat series regulating valve, sleeve cylinder series regulating valve and automatic series regulating valve.

    How can we use the regulator correctly?

    The regulator compares the measured value of the parameters of the production process with the given value, and after the deviation is obtained, an output signal is generated according to a certain adjustment rule to push the actuator to eliminate the deviation, so that the parameter is kept near the given value or changes according to a predetermined rule. controller.
