What are the characteristics of the pressure of industrial water chillers

Industry News News 1190

Industrial water chillers are one of the
most popular equipment in the machinery and equipment industry. For this
reason, the editor of LNEYA specially compiled relevant pressure instructions
to help everyone better understand industrial water chillers.

The reference value related to the pressure
resistance of industrial water coolers and piping system components refers to
the design given pressure related to the mechanical strength of the piping
components. The nominal pressure is generally expressed by PN. The nominal
pressure of the special chiller for the laboratory-the compressive strength of
the product at the reference temperature, expressed in PN, the unit: MPa, the
reference temperature: the reference temperature is different for different materials,
for example, the reference temperature of steel is 250
°C, The
nominal pressure is 1.0Mpa, which is recorded as: PN 1.0 Mpa.

The working pressure of the industrial
water chiller refers to the large pressure required for the operation of the
pipeline system according to the high working temperature of the pipeline
conveyed by the medium at all levels. The working pressure is generally
expressed in Pt.

The design pressure of an industrial water
chiller refers to the large instantaneous pressure that the water supply piping
system acts on the inner wall of the pipe. Generally, the sum of the working
pressure and the residual water hammer pressure is used, and the design
pressure is generally expressed in Pe.

The test pressure of an industrial water
cooler refers to the pressure that the pipeline, container or equipment must
reach for the pressure resistance and air tightness test requirements. The test
pressure is generally expressed by Ps.

The nominal pressure of industrial water
chillers is for the convenience of design, manufacture and use, and is a
nominal pressure artificially specified. The unit of this nominal pressure is
actually the pressure, and the pressure is the common name in Chinese, and the
unit is “Pa” instead of “N”. The nominal pressure of the
pressure vessel refers to the nominal pressure of the pressure vessel flange.
The nominal pressure of the pressure vessel flange is generally divided into 7
levels, namely 0.25, 0.60, 1.00, 1.60, 2.50, 4.00, 6.40MPa.

Summarize

Generally speaking, the pressure of
industrial water chillers can be divided into: test pressure>nominal
pressure>design pressure>working pressure. If you have any other
