A big manufacturer of packaging systems made of plastic uses 30 injection molding machines. The manufacturer of the injection molding machines recommends to change the hydraulic oil once per year although the machines are equipped with hydraulic filter systems. Because of the big oil volume 1000 l – 3000 l per injection molding machine the company decided to change the oil only once every ...
In order to drive the hydraulic cylinder normally several pumps, servo valves and a hydraulic tank with a volume between 10000 l and 40000 l of hydraulic oil is necessary. ...
The four existing presses are therefore equipped with very high-quality servo valve ...
Electrostatic oil cleaning from FRIESS In a mill for the cement industry, a lot of dust is produced as a result of the process. The control hydraulics regularly fail due to the immense amount of contamination caused by the manufacturing process. ...
One Electronic Valve Performs Better Than Two Hydraulics As part of its efforts to upgrade control of its compressor systems. ...
The valve design is capable of metering kerosene, Jet A, Diesel Fuel #2 and other similar liquid fuels (including various bio-fuels) with a closed-loop servo valve. ...
A mass flow controller consists of a mass flow monitor (MFM) and a servo-control valve. In operation, to be described in rrvore detail later, an output signal from the MFM is compared to a previously esiabhsned command signal to automatically open or close the servo-control valve. ...
The SideTrak® 830 is engineered to precisely measure the mass flow rate of process gases, and the 840's powerful servo-control valve offers precise, instantaneous control of gas delivery to a batch—as much as you need for as long as you require. ...
Monitoring the lubrication systems of plant equipment is critical for optimizing performance and reducing machinery downtime. On-site oil analysis supports condition monitoring by providing immediate answers regarding the condition of any lubricated equipment. It ensures the proper lubrication of equipment and it provides early detection of wear and helps with contamination ...
Tolerances in a hydraulic system are typically very tight. The clearances on servo valves are often on the order of 40-80 microns and the clearances on actuators can be as small as 10 microns, so particles larger than 4 microns can cause serious problems in hydraulic systems. ...
Slave devices are the instruments: the sensors, transducers, valves, servos, etc., that collect or act on the conditions in your process system. ...
This solution help you integrate four major elements including the injection molding machine, label feeding system, mold, and labels, which prevents from the risks of buying separately, and with features as below: a)Injection Molding Machine b)Material feeding driven by AC-servo motor, lessening energy consumption and feeding precisely. Adopting close-loop ...
Since the mid 1960's turbine hydraulic fluid systems have been using Fire Resistant Fluid (FRF) to control their turbine inlet valves. It is a known “FACT” that low fluid resistivity adversely affects the internal components of servo valves within the hydraulic fluid system. ...
