The hydraulic valve can be remanufactured by recollection and using professional technology.
Hydraulic oil mixed with water or too much acid, after a long time of use, some parts of the surface will produce corrosion, and then lose their accuracy or the sealing effect leads to failure.
Hydraulic valve manufacturing process The loader flow amplifying valve as an example to introduce the hydraulic valve manufacturing process: 2.1 disassembling Disassemble front with high-pressure water flushing and the old paint removal by physical or chemical method.
Every year by remanufacturing repair 2000 flow amplifying valve and the distribution valve material, can save 90%, nearly 70 tons; save fuel, water, electricity and other energy about 85%.
Hydraulic valve positive production stage, mainly the production of raw materials are iron, copper, rubber, and these materials consume large amounts of resources in the production process at the same time, also produce atmospheric pollutants, water pollutants, large amount of solid waste, the greater negative impact on the environment.

Research on self-cleaning organic Ti-Si compound material Yanwen Feng The School of biology and environmental engineering, Tianjin Professional College, Tianjin, China NO.2,Fengchan Road, Beichen District, TianJin, China.
The viscosity of the compound materials which were mutually soluble with water at any ratio is 40.9 S and the contact angle of water against composite films based glass which are made by pulling method is less than 5°.
Experiment Preparation Technology Take SG-Si900, tetrabutyl titanate, aceticacid, absolute ethyl alcohol, TEOS, Hydrochloric acid and deionized water by a certain mole ratio, lights-Si900, through hydrolysis, constant temperature polycondensation, distillation and remove by-products ,recover ethanol, get light yellow titanium-silane compound materials (ethanol content lower than 1%), put it diluted by certain proportion of deionized water, leave for a moment.
Use JY-82 type contact angle tester to measure the contact angle of water against thin film, after 2s measure when water-drop falls to the film surface.
From the figure 2 we can see that when SG-Si900/TEOS is constant, the contact angle of composite film against water gradually decreases with Si/Ti increasing, while Si/Ti doesn’t change, the contact angle of composite film against water gradually increases with SG-Si900/TEOS increasing.

The water quality parameters detection device equipped with T, pH, DO, NH3-N and S sensors can detect water quality parameters such as water temperature, pH, dissolved oxygen content, ammonia nitrogen content and salinity; the automatic bait casting device is driven by a control platform, and the automatic bait casting device can control the bait casting direction by adjusting electric turntable Ⅲ.
ARM11 equipped on the aquaculture workboat can detect the biological population distribution in the water by underwater detection device and water quality parameters detection device and provide sailing or operation information for the workboat.

Introduction Tidal energy, water potential energy formed by high tide and ebb flow of seawater, is proportional to tidal capacity and tidal range, and its development and utilization of the principle is similar to hydroelectric power.
Besides, professionals believe that the development of tidal energy can not only alleviate the shortage of energy, but also have good comprehensive utilization benefit around the reservoir.
Statistics of Jiangxia power station in 1999 showed that gross output reached 36.8 million Yuan, only plantings in the reservoir area, reclamation ponds, beaches and water aquaculture, net income to 755 million.
On hydropower calculation, Liu (1999) got a reasonable calculation of the maximum flood level with view of the most unfavorable combination of the operation of tidal power plant( generating power and filling water) meeting the flooding peak—the High tide’s effects on the flood backwater.

Technological process Laying seedling carrier→loading bed soil→watering→seeding→soil covering Determine the seeding period Push back the suitable sowing period according to the age of the proper machine transplanting seedling and the local conventional planting time.
If there is heavy rain or drain water, stagnant water should be avoided in the seedbed.
Control water before transplanting to promote seedling packing.
With the rice transplanter as carrier, Machine operator or transplanting machine company, professional cooperatives carry out unified service forms of unified seedling varieties seedling, transplanting to promote the new technologies and the new varieties of rice, the rice regional distribution, scale and standardization production.
It also opens up a channel of increasing income for the machine operators or seedling company and professional cooperatives.

It can also work as a stand-alone water dispenser.
A mason jar was used as the water container, with the water tank HC-SR04 attached to the lid.

Fig. 1 Automatic industrial washing machine (uncovered) According to the information provided by the sponsor, the podávacom devices are malfunctioning for the following reasons: - In the bowels of the drive gets water from the scrubbers, resulting in increased wear and stress on the pneumatic actuator
Fig. 4 The main force and torque load on the main drive Festo DGPL Equally serious is the already mentioned water condensing from water vapor along with chemicals that are found in the cleaning equipment in the industrial washing machine.
The fact that winch is located at the top of the motor cylinder, when the movement often has been the case, that is part of the condensation of water vapor, along with chemical solids get into the bowels of the actuator.
On the basis of the measured data and the views of experienced professionals who can carry out measurements to conclude that the test samples to maintain their properties and the mechanical point of view, there has been no significant change in the structure of the surface, or mechanical properties of the test material.

Test devices and arrangement Water Circulation System.
Groundwater reservoir pumping water through the water pump to the pump room of high level water tank at the top of, control valves for water supply pipe into the Weir, before entering the Import pool, flows through the model back to the underground reservoir, forming water circulation system.
Water circulation system are shown in Figure 2.1 Figure 2.1 Diagram of the water circulation system Test Measurement Instruments.

The window sashes should be glazed, heating, water and electricity should be connected.
In fact, to become a professional mechanized spraying plaster compositions is not difficult.
As a rule, even if the company leases machines with guide, after two or three days plasterers of this company themselves become professionals and subsequently lease only technique.

According to the test of professional departments, performances of GT materials (GT flexible waterproof material type Ⅱas an example) are shown in table 1 [1].
Preparation of GT rigid coating mixture ratio is the weight ratio ( paint: water = 1: 0.7), preparation of GT flexible coating mixture ratio is the weight ratio ( paint: water: GT slurry = 1: 0.5: 1.5), workers should reduce or increase the weight of water appropriately according to the climate and environment, stirring time shall not be less than 5min.
Powder and GT main liquid should be no water or rain, to prevent failure after water reaction.
