The invention provides a pressure boosting device of a hydraulic system. The pressure boosting device comprises a hydraulic motor, a hydraulic pump, an oil tank and an energy accumulator, wherein oil flows into the motor from a pipeline to drive the motor to rotate; the pump pumps the oil from the oil tank into the energy accumulator, a certain amount of pressure is inflated into the energy accumulator in advance, an output shaft of the motor is connected with an input shaft of the pump, the hydraulic motor rotates to drive the hydraulic pump to rotate, and the discharge capacity of the hydraulic motor is larger than that of the hydraulic pump so that the large discharge capacity motor drives the small discharge capacity pump to convert low-pressure oil from a pipeline into high-pressure oil to be stored in the energy accumulator. By means of the pressure boosting device of the hydraulic system, surplus energy such as potential energy in the system can be conveniently converted into hydraulic energy to be stored, and the hydraulic energy is supplied to the system when the system needs more energy, so that environment-friendly and economical effects are achieved; the stored energy can be used as a high-pressure source to provide high-pressure oil for the hydraulic system, so that addition of a single high-pressure pump is avoided, the size of the system is reduced, and costs are reduced.

The invention discloses a capsaicin-like compound and a preparation method and use thereof. The capsaicin-like compound has a molecular formula of C27H21N2O9F3ClBrR. 4-bromo-2-(4-chlorophenyl)-5-trifluoromethylpyrrole-3-nitrile, capsiate and glucurnic acid as raw materials are dissolved in a benzene solvent, the solution undergoes a catalytic backflow reaction for 4-8h, the reaction product is washed and dried, and the dried product is subjected to distillation and recrystallization. The preparation method utilizes the easily-available raw materials and has a low cost and a high yield. The capsaicin-like compound as an antifouling agent can be fast degraded in a seawater environment, has small influence on marine organisms, is difficultly accumulated in organism, and has low toxicity, good antifouling effects and a long service life.

The traditional Chinese medicine raw material dicing device capable of reducing the breakage rate is stable in structure, reasonable in layout, stable in running, capable of achieving continuous dicing processing for traditional Chinese medicine raw materials, and capable of effectively reducing the dicing breakage rate, and meets current use requirements.

A hydraulic pressure boost energy recovery system and control device, wherein the hydraulic pressure boost energy recovery system has two groups, the first group consists of a first solenoid valve, a first hydraulic pressure booster, a first one-way valve, a second one-way valve, the third one-way valve, the fourth one-way valve, the second group consists of the second solenoid valve, the second hydraulic booster, the fifth one-way valve, the sixth one-way valve, the seventh one-way valve, the It is composed of eight one-way valves; the control device of the hydraulic booster energy recovery system includes an electronic control unit and a flow sensor; the rest of the hydraulic devices include an accumulator and a fuel tank. The low-pressure oil passes through the first pressure booster and the second pressure booster, and is transformed into high-pressure oil and stored in the accumulator to complete the recovery of pressurized energy. The electronic control unit adjusts the working positions of the first solenoid valve and the second solenoid valve to be opposite according to the signal of the flow sensor, and controls the movement direction of the first pressure booster and the second pressure booster to be opposite to avoid hydraulic shock.

The invention discloses a geotechnical centrifuge driven by a synchronous belt transmission device. The geotechnical centrifuge driven by the synchronous belt transmission device comprises a main shaft and a motor which are mounted vertically; a rotating arm is horizontally arranged at the upper end of the main shaft; a large belt wheel is arranged at the lower end of the main shaft; a rotating shaft of the motor is provided with a small belt wheel; the small belt wheel is in transmission connection with the large belt wheel through a synchronous belt; two tensioning wheels are arranged on the outer side of the synchronous wheel. According to the geotechnical centrifuge driven by the synchronous belt transmission device, a layered construction structure which is driven by adopting the motor or driven by the motor and a speed reducer in the prior art is changed, and the construction cost is lowered; the requirement on continuously supplying a large amount of water, oil and gas to the rotating arm through an inner hole of the main shaft when the centrifuge operates can be met; the synchronous belt has certain effects on vibration damping and noise reducing; an additional acting force generated by imbalance of the rotating arm or vibration of a vibrating table can be absorbed to a certain degree, and the impact on a construction foundation caused by the additional acting force is reduced; the synchronous belt is reliable in work, simple in structure, and convenient to maintain and replace.

PURPOSE: The addition of the separate tool is avoided to the border of the tubular knitting fabric. Stitch is not included. It can prevent that stitch is destroyed. CONSTITUTION: In the weft knitting machine for the tubular knitting fabric knitting. It digs the jack guide. It is close to of the jack passes through to the reverse direction(23R) path. The difference of ΔL in amount of the knitting needle it returns is occurred. The difference of the high-to-low in the projection amount from the needle groove is formed.
