![]() ![]() Safety valve is used to discharge excess compressed air inside the It prevents equipment damages due to excessive pressure in filled by cement trailer or pneumatic conveying system.Īudible and illuminated alarm is activated if the system needs to warn the user. ![]() System does not operate if there is no air pressure. Safety System Componentsįilter is a cylindrical shaped dust collector used for ventilation of pneumatically filled Dust, separated from the air by special filter elements, drops back into the after an integrated automatic reverse air jet cleaning system inside the weather protection cover removes it from the filter elements.įor safety purposes, the filter and the pinch valve control the required air pressure. Elimination of possibility of faulty filling. Tracking of the raw material level inside the Contribution to work safety of the plant. Left cement is cleaned up by pushing “SYSTEM START” button. To open Pinch Valve of the related “VALVE OPENED” button must be pushed.ġ0. To clean up cement left in the pipe, “MANUAL OPERATION” must be switched to position “1” while “ FILTER” is active. To reset the filling alarm, “ALARM MUTE” button must be pushed.ĩ. Audible and illuminated alarm goes on after 45 seconds and system automatically deactivates Pinch Valve.Ĩ. Whenever required, “SYSTEM STOP” button must be pushed to stop the process.ħ.FULL” light becomes active when cement reaches the level indicator. For initiating filling process, “SYSTEM START” button must be pushed.Ħ. “FILLING START” light will become active when pinch valve is opened.ĥ. ![]() Pinch Valve of the to be filled must be opened by “VALVE OPENED” button.Ĥ. Filter of the to be filled must be activated by “FILTER” button.ģ. “AIR FULL” light will be on if there is an air pressure.Ģ. Air pressure required to run the system must be checked. Preventing Cement Overpressure in 10 stepsġ. Moreover, they can be installed as a locking device for filling pipes. VM and VMM-type Pinch Valves are used for interception of material flow in pneumatic conveying systems or in other pipelines. The sleeve support bushes are either made from aluminum alloy, hardened carbon steel or 304/316 stainless steel. The body of VM/VMM Pinch Valve is manufactured from aluminum alloy while the sleeves come in fabric-reinforced material. The top or side-mounted indicators are commonly used in powdery and granular material applications. When material level reaches the measuring paddle rotation is blocked and when level sinks below the paddle radius rotation restarts and activates other system components. One of the main reasons of flawless operation of Safety System is the preference of WAMGROUP Level Indicator and Pinch Valve in our system. Our control system, which is targeted to minimize component damages, automatically takes necessary precautions during the filling process, operates related equipment and alerts user when needed. Insufficient ventilation and level gauge errors, which cause excessive pressure, can lead to serious damages in MEKA’s Filling Control System prevents both excessive pressure and ventilation filter and equipment damages which can be arisen from overfilling. The main reason of damage in and equipment is an overfill and excessive pressure occurring during the filling. This system, which is used particularly in which are being filled with cement trailer, has been designed in a customizable way in order to fit conditions in the field. MEKA, who has made a name as a company providing cutting-edge automatization solutions, owns an advanced Control System consisting of WAMGROUP components which can be integrated with equipment. ![]()
