Sometimes when the customer buys back the pressure controller, due to the carelessness of the construction unit causing the pressure controller to install is not vertical, it will affect the vertical movement of the pressure pointer along the scale (the realization of which has basically avoided this problem in the presence of a digital pressure controller), Can not move very well, so that the sensitivity is affected. What is the correct installation? (1) Open the cover and hold the controller vertically on the instrument bracket. To prevent changing the performance, avoid using the tool or hand to dial the arm. (2) Remove the lock nut and rotate the adjustment lever. Point the pointer to the desired pressure setting position and tighten the lock nut. (3) Rotate the switch differential knob to obtain the required switching difference. This switch can be adjusted in addition to the operating pressure, and the differential value of the switch recovery can also be adjusted within a certain range. For example, the pressure controller's T. for pressure adjustment range is 0-1.47MPa. The switch's action pressure value can be adjusted within this range 114. The differential value between the action switch and switch recovery can be 0.1-0.27MPa. Inter-regulation. This shows that a switch can achieve two-state pressure control. (4) Unscrewing the joint, the metal pressure pipe with a diameter of 6mm will be brought along with the device and one end is soldered to the sleeve. After soldering, the joint is rotated and the connecting pipe is sealed. The controlled medium is composed of a metal pressure guiding pipe. Enter the ripple chamber of the controller. In order to avoid the access. Pipe connection should pay attention to the size of the pipe fittings and the pressure pipe match. (5) Check if the pressure controller is installed correctly. After the cover is installed, turn on the power supply. Perform calibration according to the pressure controller. After the adjustment is completed, the rotary knob must not be turned again. (6) Membrane pressure gauges, also known as wind pressure gauges or micro-pressure gauges, are used to measure the arrogance and micro-negative pressure of blast, induced draft, flue gas and pulverizing systems. They can also be realized by electric contact pressure gauges. Control pressure and protection functions. Before installation, check if the diaphragm pressure gauge is intact. The above does not outline all the on-site installations. Some installations also need to combine actual needs with process requirements in order to achieve better results.
