Plastic with synthetic resin and synthetic rubber, synthetic fibre new profile of high polymer of 3 kinds of big synthesis expects, had made the material of 4 large bases in modern society together with steely, lumber, cement, it is information, the sources of energy, industry, agriculture, traffic is carried and even the national economy such as astrospace and marine development the new-style material with each indispensable domain. Industry of plastic products treatment is light industrial one of development rate is rapidder in last few years industries in the industry, as the grow in quantity of plastic industry measure, reduce manufacturing cost, raise product competition ability to become the issue that a lot of plastic products plants care jointly. In finished cost, charge of electricity held quite large proportion, and the machine noting model with numerous amount is the equipment with bad news most report, accordingly, energy-saving to noting model machine to undertake technical reformation appears very pressing and necessary. On the machine that note model promotion application transducer can achieve managing electric energy, improve productivity and product quality, reduce oily pollution and noise pollution, lengthen machine service life to wait for an advantage. Accordingly will progressively promotion is used.

The 1 machine that note model the plan of frequency control system
The work of the 1.1 machine that note model is as follows circularly:
1.1.1 locks combine a model: Fei of pancreas of 0 Dan ¬Ç holds ¨Ä of the ü¶ of Pai of 0 Jian stew that chant banter of Bi of Tuan burnt Californium protects «Ä of ¬½ of stalk of crash of ª¸ of ªÎ of ¬Ï low spoon 0 Hou øº is rare
Reach of 1.1.2 inject stage: Qian warmths ablaze ù¡ of Xian of peptide £¾ talk in one's sleep
1.1.3 inject: ¢É Guan showing disrespect or contempt break ¦º of joyous ¨µ hard sell to retreat bank of virtuous pay attention to of Yu Ran «Á to say graceful Ge displays arc of ¢È peptide G
1.1.4 protect pressure, cooling: Closely question of barren of G of beat of ¬Ê of sole of ¯× of ¨¹ ý´ large ancients name for a water catltrop to be defeated now therefore prevent Cong to enter Shang Wei
1.1.5 beforehand model:
1.1.6 inject stage is regressive, fly a model
1.1.7 give product
These movements are in above is finished on the traditional engine that note model with hydraulic pressure system. By the cooperates generation to differ pressure direction of oil pump and different valve and discharge, offer oil cylinder and the impetus that hydraulic pressure motor asks and floating rate.
Well-known, the output power of oil pump
N of ¡Á of V of ¡Á of Pt=p ¡Á Qt=p (1)
And the academic torsion of oil pump:
V of ¡Á of P of Tt=1/2 ¦Ð ¡Á (2)
The P in type is pressure, qt is discharge, v discharges an amount for oil pump (oil pump every turn the oily quantity of eduction) , n is oil pump rotate speed
Will (2) type takes the place of (1) type gets:
N of ¡Á of Tt of Pt=2 ¦Ð ¡Á (3)
