What are the selection skills of plate heat exchanger units

Date:2020-09-07

Which key points should be paid attention to when selecting plate heat exchanger units? I believe this problem has made people a little heady! Plate heat exchanger units have become one of the indispensable equipment for our daily heating equipment. The scope of application is also relatively wide. Whether it is food cooling, district heating, or industrial fields, the existence of heat exchanger units is indispensable. What is the method for selecting plate heat exchanger units?

The selection of plate heat exchanger units mainly depends on the following aspects!

One, understand the equipment

1. Materials

Look at the material first, because the material is very important to the equipment and is related to its own process. In addition, the material of the plate heat exchanger unit is also related to the price. The price of titanium is higher than the quality and price of stainless steel. However, the specific situation still depends on its own process. For example, some customers want to use stainless steel for centralized heating. Good satisfaction! And stainless steel is of high quality and durable.

2. Specifications

To understand the material, almost start to look at the specifications and perform experimental calculations. To have sufficient understanding of the size of the equipment. Check carefully whether part of the control system and each component, valve, sensor, etc. are qualified, and carefully check the temperature controller, transmitter, switch machine and other parts.

Second, equipment standards

When selecting plate heat exchanger units, you need to understand the basic conditions of the equipment of Zhejiang Forwon Plate Heat Exchanger Co., Ltd :

 

 

1. Area

Consider the land occupation requirements of the equipment according to its own factors. A certain distance should be left around the equipment to facilitate subsequent operations. For the equipment, our rated power needs to meet the system parameters.

2. Layout pipeline

The make-up pump and the circulating pump must not only be equipped with softening joints, but also with a shock-absorbing design. The pipeline should be reasonably arranged to facilitate maintenance, repair and cleaning in the later period, and reduce a certain operating resistance, reduce the distance of the pipeline, and increase the heat exchange efficiency.

3. Temperature

General temperature is also a key consideration. The user's operating temperature will generally not exceed 75°C. If it is used in the chemical industry, the temperature may reach 300°C.

Third, the appearance of the equipment

The appearance of the equipment is also a point we should pay attention to. It does not depend on the "appearance" of the equipment, but the appearance is also closely related to our craftsmanship. There must be no bubbles, wrinkles, defects, impurities, etc., and there must be no damage or breakage. Check whether the nameplate is worn or unclear, which will affect our later use.

Check whether the equipment has protective components, leaks, etc., try to extend our service life, and protect the process environment from being affected.
