Small excavators can be used to dig greenhouses and ditches. This is a small excavator that can be used indoors. Saving labor and space is a rare advantage. It is widely used in the water business. Low cost purchase and high survival rate is everyone's evaluation. Not surprisingly, microshovels are also being used to build power projects. Filling the rod was previously a difficult task, as one had to use manual drilling and it was inefficient. Now everyone is using small excavators, nearly ten times faster than before. The other is called a multi-purpose mini excavator: not only does it have a bucket, it can also damage the ground and be equipped with a crushing hammer to tear down the house. Adding an auger can be a great aid in gardening tree holes and planting. Compared with ordinary excavators, micro drilling machines are small in size, easy to operate, and choose the built environment that many people like. Today, Xiaobian introduces how micro-drilling machines can help orchard construction in order to better understand micro-drilling machines.

The direct-acting solenoid valve is used for small-caliber and low-pressure fluid media. When the structure of the direct-acting solenoid valve is opened, it does not require the opening pressure of the medium and can achieve zero-pressure start. To extend its service life, it is recommended to install it horizontally with the coil facing upward. The direct-acting solenoid valve features a small size, large flow rate and fast response speed. It is particularly suitable for occasions requiring high opening and closing frequency or rapid shut-off.

The zero-differential-pressure solenoid valve combines the principles of direct-acting and pilot-type. When there is no pressure difference between the inlet and outlet, after energization, the electromagnetic force directly lifts the pilot small valve and the main valve closing part upward in sequence, opening the valve. The zero-differential-pressure direct-acting solenoid valve can also operate at zero differential pressure, but it has higher power and must be installed horizontally.
