The majority of composite oil composting presses need to be equipped with a server hydraulic system, also known as a server. Special features of energy efficiency, efficiency, low noise, low heat, high control accuracy and ease of repair, as follows:
Features of the server system:
(i) energy efficiency:
The energy efficiency of this liquid server drive is significant compared with traditional hydraulic presses, which can save 20 to 60 per cent of electricity depending on the process and production rhythm。
(1) when the slider is fast and the slider is still at the upper limit, the server does not move and therefore does not consume power. Traditional hydraulic presses continue to rotate at a rated rate and still require energy consumption of 20-30% of the rated power (including electric cable, friction of oil pumps, hydraulic channel resistance, pressure-relief valves, mechanical transmission connections, etc.)。
(2) the servo-driving hydraulic presses, during the pressure-push phase, are converted at speeds only to supplement leakage of the pumps and systems, usually between 100rpm and 1500rpm, with a power consumption of only 1-10% of the rated power. Traditional hydraulic presses, depending on how they are protected, actually consume 30-100 per cent of the rated power during the pressure phase。
(3) the efficiency of the server and the average electric power is about 1 to 3 per cent higher, which determines greater energy efficiency for the server-driven hydraulic press。
(ii) low noise:
The oil pumps of this liquid server drive are low noise pumps, the traditional hydraulic presses are typically axle-directional pistons, and the noise ratio of the low noise pump is 5db-10db. The server is 5db-10db. Less than the pole pump under the same flow and pressure, and the server hydraulic press is operating at a rated turn-off speed at the time of suppression and return, and its noise is 5db-10db. It is less than that of the traditional hydraulic press. When the slider fast-down hydraulic press is static, the server turns zero, so there is little noise in the server. The noise of the server hydraulic presses is generally less than 80 db during the pressure-push phase due to the low speed of the electric press, whereas the noise of the traditional hydraulic presses is 80 db-100 db。
(iii) low fever:
Reducing the costs of refrigeration, reducing the costs of hydraulic fluids, servulating the hydraulic system of the hydraulic press without spilling heat, and no flow flow during the stationary flow of the slide block, so that it does not have hydraulic resistance to heat, which generally amounts to 10-30 per cent of the conventional hydraulic press. Due to the low heating of the system, the general server-driven hydraulic presses may not have hydraulic oil cooling systems, and some of the larger heat-producing systems may have small power cooling systems。
The amount of oil used and the tanks are smaller than the normal hydraulic presses: because the pumps are mostly of a zero-rotation rate and a small heat point, the tanks that serve the hydraulic presses can be smaller or longer than the conventional hydraulic presses, so the hydraulic fluids that are consumed by the driver are generally only about 50 per cent of the conventional hydraulic presses. A high degree of automation, a high degree of flexibility, a high degree of accuracy, a high level of server-driven hydraulic pressure, speed, position of full closed circle digital control, a high degree of automation and precision. The pressure is also programmable to meet various process requirements。
(iv) efficiency:
Through appropriate speed-reducing controls and energy optimization, the speed of the servicing of the control hydraulic press can be significantly increased and the work beat can be increased several times more than the traditional hydraulic press, to 10/min-15/min。
(v) control accuracy:
The pressure control chain of the servo-pump system is closed-ring control, with pressure sensors measuring the pressure of the system, which does not vary depending on the fluid viscosity of the oil temperature, so the pressure control is high, repetitive and improves the quality stability of the product。
(vi) maintenance facilities:
As a result of the removal of the proportional server hydraulic valves from the hydraulic system, the speed of the circuits, and the pressure circuits, the hydraulic system was considerably simplified. Cleanness requirements for hydraulic fluids are much smaller than the hydraulic ratio server system, reducing the impact of hydraulic oil pollution on the system。
