The three-wheel suction truck is a device widely used in rural methane tanks, manure pools, fish ponds, etc. It can also be used to clean up wastes and urban sewage. It is easy and flexible to use and has high work efficiency. The working principle of the three-wheel suction truck can be understood from the following aspects.
First, the workflow. The operation of the three-wheel suction vehicle is to discharge the air in the sealed tank to form a vacuum inside the tank. The pressure inside the tank is less than the atmospheric pressure. A connected pipe can be used to put the excrement pool, digester or fish pond. The waste inside allows the atmospheric pressure to propel the tank, thus achieving the purpose of the suction truck operation. The core of this process is the use of a vacuum pump. It can be mounted on a tricycle to drive the air inside the tank through the engine, and it can also be operated by an electric motor.
Second, the suction pump vacuum pump works. The vacuum pump is the core equipment of the suction truck. Let's take a look at how it works. The rotor inside the vacuum pump rotates at a relatively high speed. The blades in the pump will slide against the inner wall of the pump under the effect of centrifugal force. This will increase the capacity of the suction, and the gas withdrawn from the tank will enter. To the inside. As the rotor continues to rotate, the extracted air is gradually compressed, which creates a high pressure. When this pressure exceeds the pressure at the exhaust port, these gases can be discharged. After a certain period of time, the air inside the tank can be discharged to form a vacuum. Afterwards, the suction truck can start working until the entire work is completed.
Third, the problem that should be paid attention when using a three-wheel suction truck. When working with a suction truck, pay attention to the installation and use of the vacuum pump. If the tricycle itself cannot provide powerful power, then an external engine is required so that the effect of pumping the air out of the tank can be achieved. In addition, the vacuum pump of the suction truck is generally an oil pump. Pay attention to adding oil and antifreeze oil to ensure that the equipment can be used normally.
We can supply big range of such stainless steel Casting Parts, including investment casting and Sand Casting
Sand Casting method (Sand Casting)
Using Sand as Mold material, according to the different components of Sand can be subdivided into wet Sand casting method of Green Sand Mold), surface Dry Sand casting method (Dry Sand Mold), and so on, but not all are available in the casting.
Advantage is lower cost, because the sand mold use reusable;
Lost wax Casting, Investment Casting
This method can be as the outer membrane casting method and the solid casting method.
To copy wax casting items required first, and then into the pool with ceramic and stay dry, make with wax replica is covered a layer of ceramic outer membrane, repeat steps until enough to support outer membrane casting process (about 1/4 inch to 1/8 inch), then the wax melting mould, and out of mold. Then mold need to high temperature for many times, enhance behind the hardness could be used in the casting.
This method has good accuracy, can be used as a high melting point metal, such as titanium casting.
