Changzhou Liangbang Instrument Co., Ltd. is a company that has many years of experience in manufacturing, design, R&D, sales and processing. The glass rotor flowmeters, metal tube float flowmeters, electromagnetic flowmeters, smart turbine flowmeters, vortex flowmeters, magnetic flap level gauges, pressure gauges, bimetal thermometers, and other best-selling consumer markets are produced . Here focuses on the pressure gauge
A pressure gauge is an instrument that uses an elastic element as a sensitive element to measure and indicate that it is above ambient pressure .
The structure of the pressure gauge:
Overflow hole: In the event of an emergency in the Bourdon tube burst, the internal pressure will be released to the outside through the overflow hole to prevent the glass panel from bursting. Note: In order to maintain the normal performance of the overflow hole, leave at least 10mm behind the table and do not modify or plug the overflow hole.
Pointer: In addition to the standard pointer, other pointers are optional. (Zero pointer maximum pointer or setting pointer) Please list in the selection table.
Glass panels: In addition to standard glass, other special materials such as tempered glass and non-reflective glass are optional.
Performance classification: normal type (standard), steam type (M), heat resistant (H), vibration resistant (V), steam resistant (MV) heat and vibration resistant (HV).
Treatment method: Oil-free or water-repellent treatment Remove water or oil remaining in the wetted part during production.
Exterior Designation: Shell Color In addition to the standard colors, please specify.
Throttle valve: (optional) In order to reduce the pulsating pressure, the throttle valve is installed at the pressure inlet.
Pulsating pressure: Due to the pulsating nature of the pump in the generator, the amplitude of the special curve of the pressure gauge is larger. This is very harmful to the pressure gauge.
Pressure gauge selection notes:
1 Instrument name: To be clear is the general pressure gauge, oxygen pressure gauge, electrical contact pressure gauge, ammonia pressure gauge;
2 instrument model: There are different models for different manufacturers, but clearly written in the contract;
Accuracy grade: 1.0; 1.6; 2.5; 4.0
The outer diameter of the instrument: Φ40, Φ60, Φ100, Φ150, Φ200, Φ250.
5. Installation: radial, axial, with front, with back.
6. Measurement range: vacuum gauge - -0.1MPa
Pressure gauge - measuring upper pressure vacuum - measuring range
7. Connector thread: M10X1; M14X1.5; M20X1.5
Under special circumstances, the following points should be clearly defined according to different pressure gauges:
1. Instrument name: Diaphragm pressure gauge, antiseptic pressure gauge, shock pressure gauge, diaphragm pressure gauge, etc.
2. Diaphragm pressure gauge:
a. According to different uses, the filling liquid in the spring tube (silicone oil, glycerin, edible oil, fluorine oil, etc.) should be clearly defined
b. According to the corrosion of the measured medium, the material of the diaphragm (such as SUS316, Tantalum, titanium, Monel, Hastelloy, coating, etc.) should be clearly defined.
c. If it is a flange connection, the implementation standard, size, material, etc. of the flange should be clarified
3. The shock-absorbing pressure gauge should be clear in the case of vibration damping fluid (silicone, glycerin, etc.)
4. Corrosion pressure gauges shall be based on the corrosiveness of the measured medium or the corrosiveness of the working environment, and the materials of the joints, spring tubes, and watchcases shall be clearly defined.
Changzhou Liangbang Instrument Co., Ltd. is located in Tianning Economic Development Zone, Changzhou City, Jiangsu Province. It is close to Shanghai-Nanjing Expressway and Beijing-Shanghai high-speed railway. It is only 30 kilometers away from Changzhou Airport and Yangtze River Terminal.
