The configuration structure of prior art horizontal screw centrifuge, its layout is through the long-term test structure relative fixed of using, compact, operate steadily, bigger change is done in inconvenience, otherwise not only cost will have bigger rising, and can bring problem to job stability, the reliability of other parts, so the present invention designs and layout centrifuge, Hydraulic Station on the prior art basis as far as possible.But distinct issues are in transformation: 1. two oil inlet pipes of prior art are respectively by two oil pump feeds, than being easier to control oil circuit, reach the pressure at two ends, and the present invention is in order to be configured in Hydraulic Station on the frame of centrifuge, for compact conformation, what reduce cost use is single pump configuration.Hydraulic Station is to be configured in the motor back space of frame, depart from the center with respect to centrifuge, therefore the relative centrifuge of pipeline is an asymmetric arrangement, the oil-out of single pump is difficult to be positioned at the centre position of centrifuge two end axles bearing, the difference of pipeline length certainly will cause two-way fuel delivery inequality, and one road fuel feeding is too many, and another road very little, influence the uniform distribution of thin oil, both of these case all is unfavorable for the stable operation of thin oil lubricant bearing; 2. owing to be subjected to placing restrictions on of installing space, consider the stability of device, also for attractive in appearance, Hydraulic Station bottom fuel tank volume is as far as possible little, and is low as far as possible, but for oil return is unobstructed the space of oil sump tank top increased, and highly increases, and has contradiction around here.
In technical scheme of the present invention, adopted oil-feed flow speed control valve element, it is the opening and closing that come by-pass valve control according to both sides, front and back input pressure, makes the oil pressure of centrifuge rear and front end reach mutually degree stably.Therefore, even Hydraulic Station departs from center configuration with respect to centrifuge, centrifuge two ends pipeline length difference, but by the technical program, still can guarantee the pressure unanimity at two ends.
Secondly, fuel tank of the present invention has adopted oil feeding reservoirs and two branch fuel tanks of oil sump tank, is configured in the bottom of device side by side, and the bottom of two fuel tanks is interconnected, and connects vavuum pump on the top of oil feeding reservoirs.Hydraulic Station bottom oil tube adopts two box structure designs, with plate fuel tank is divided into oil feeding reservoirs and two cavitys of oil sump tank, and certain interval is arranged at the bottom, and two cavitys are communicated with, and connects vavuum pump on the top of oil feeding reservoirs.It is poor that this structure Design can increase between bearing block oil return opening and the Hydraulic Station oil return opening level height, make oil return smooth and easy, its operation principle is: behind charge of oil in the fuel tank, oil mass is approximately the 1/2-3/4 of oil cylinder volume, then negative pressure state is pumped into by vavuum pump in oil feeding reservoirs top, and oil sump tank is communicated with atmosphere, there is pressure differential in pasta in two cavitys, form difference in height, oil feeding reservoirs oil level H is higher than oil sump tank oil level h, level height difference Δ H=H-h.When Hydraulic Station was worked, the oil in the oil feeding reservoirs was constantly extracted out by pump, sends into bearing block, H reduces, because upper space is a negative pressure, by the atmospheric effect in oil sump tank top, the oil in the oil sump tank constantly is pressed into oil feeding reservoirs, make H get back to the origin-location, Δ H does not change simultaneously, and so circulation just can be kept h at lower position, make the outlet of oil return pipe that bigger drop be arranged, keep the unimpeded circulation and the operation of system.For guaranteeing effective operation of twin-tub structure, increase minipump, and adopt logic control, stablize negative pressure to keep the oil feeding reservoirs upper chamber, rely on simultaneously and regulate vacuum magnitude, control the oil sump tank level height.
Advantage of the present invention and superiority: the Hydraulic Station of the technical program is installed on the horizontal screw centrifuge frame, and Hydraulic Station is connected with oil pipe with bearing block, forms the thin oil closed circuit.This design has made full use of remaining space on the frame, saves site space, has saved transportation and the problem that trouble is installed in the split-type structural simultaneously, speeds up the work, and raises the efficiency.
Single pump two-way double-cylinder hydraulic station and horizontal screw centrifuge integral structure can improve engineering efficient, reduce cost.Adopted oil-feed flow speed control valve element, it is the opening and closing that come by-pass valve control according to both sides, front and back input pressure, makes the oil pressure of centrifuge rear and front end reach mutually degree stably.And vavuum pump is set above oil feeding reservoirs, utilized principle of negative pressure dexterously, the below of oil feeding reservoirs and oil sump tank is interconnected, guarantee that oil sump tank has bigger drop, guarantee the smooth and easy of oil return, reduced the whole height of fuel tank again, solved the problem that the integral type design brings, for good condition has been created in the stable operation of thin oil lubricant bearing.
