1. Technical parameters:

Medium: material a: composite polyether (POL)

Material B: carbon dioxide

Viscosity: pol: 2000cp

20 ml / ml: 10 min

Temperature and pressure: normal temperature. Pressure: 150kg

Power source: pressure tank (inserted by plunger pump)

Detection method: flow monitoring (control the proportion of AB component)

Display: do not need to display, receive a pulse signal.

Specific working condition: how to realize the ratio monitoring and control of two components on the high pressure foaming machine of polyurethane applied by customers? The two-component flow is transmitted to the PLC on site through the pulse signal of the flowmeter. When the set flow rate is different from the actual flow rate (the flow value monitored by the flowmeter), adjust the pump or valve on site to achieve proportional control.

2. Why flowmeter is used

A. because the national requirements for environmental protection are higher and higher, freon was used as foaming agent in this industry before. This kind of medium is not environmentally friendly and needs to be banned by the state. Replacing Freon with carbon dioxide is not only environmentally friendly but also cost-effective. However, there is a problem. Freon can be produced by mixing it in proportion in advance. However, carbon dioxide can not be controlled and can only be used to accurately measure the specific gravity through the flowmeter.

More or less B, a and ab materials can not be found in time, resulting in more equipment scrapping.

In case of uneven dispensing, the staff can not receive the alarm signal in time, which will disrupt the original work plan. What's more, if the goods are handed over to the customers, they will find that it will bring huge negative impact on the cooperation and damage the professional image of the company.
