Shandong Sheng Machinery Co., Ltd specializes in producing various types of brick, brick machine, brick machine, hollow brick, brick pavement and other equipment of the old brick factory.
    In plc programming block brick program by setting the value of P, I and D of these three parameters you can use to adjust the proportional valve valve opening, the control system flow requirements at each stage. As a result of proportional control, precision fluid through the addition of a suitable filter control.
Proportional throttle valve opening control will achieve its control signal. Proportional throttle characteristic decision: it is not a control signal is a digital signal, but an analog signal. Each analog signal values corresponding to a valve opening, brick-making machine that passage orifice area
Put a new term electromagnetic proportional throttle introduce to you. Yesterday, speaking on proportional relief valve and electromagnetic relief valve function is not much difference, is open relief overflow when the system pressure exceeds the set value; the difference is that the ratio of adjusted proportional relief valve can be set overflow traffic, more precise control of the system. General relief is both open and closed positions, the proportion of the overflow valve in the open position can have more than one.
In the proportional valve Importers difference is constant, the opening degree of the valve port cement brick directly determines orifice cross-sectional area, so that the respective desired flow rate by the control signal determines. Thus, the proportion of the throttle in its adjustment range, can achieve anything we need to adjust the flow through the control signal, the actuator to meet the requirements of the various stages of the work. Also, because we can control the input signal to the valve port opening, so the valve commutation process, we can reasonably control the signal to reduce the cement brick machine hydraulic system commutation shock.
Shandong Sheng Machinery Co., Ltd has been committed to cement machinery products development, production and sales, with advanced equipment, professional and technical skills, and two decades of experience, the company has always been at the forefront of research and development center block molding machine market development Follow the advanced technology at home and abroad, to develop products for different investment needs of the user, the main block making machine, hydraulic tile machine, cement pipe machine, mixer, hanging roller machine, wire rod machine equipment.
