A fully re-equipped lab sieve at Chenwei Corporation contains a full range of screening and fluid bed processing equipment that is readily reconfigured to simulate customer installations for trials using supplied materials. All models of laboratory sieve are quick-clean designs allowing easy access to interior components for rapid inspection, disassembly, screen changes and cleaning. Most notable is the lab's new, full scale, fluid bed processing equipment for drying, cooling and moisturizing of bulk solid materials. The exclusive, circular vibratory design enables entire systems consisting of fluid bed processor, heater/cooler/moisturizer, blower and dust collector, to be self-contained on mobile frames with casters, offering testing flexibility not practical with larger, heavier, rectangular units of equivalent capacity.
There are two Test Sieve for lab,one is standard test sieve,the other is electromagnetic vibration sieve.In comparison,the electromagnetic vibration sieve has mush higher accuracy for particles size distribution test. Up to 600 mesh sieve can be used on it.
Feature
* Lab use for particle size analysis.
* High efficiency and high precision,
* Tight Structure and low noise
* Precise timer function
* Up to 600mesh can be test

It is important to note that when fuel tanks with fuel dispensers are metered outwards, the idle speed must not be too high to prevent excessive pressure from damaging the oil pumps and dispensers.
Recently, the sales of mobile refueling vehicles have become increasingly popular. Many users have for the first time been exposed to fuel tanker special equipment such as computer tax-controlled mobile fuel dispensers. Therefore, some considerations in the use of fuel dispensers are not well understood:
1, the flow operation method of computer tax-tanker refueling vehicle: when the mobile tanker truck refueling, lift oil gun, the switching signals fed to computer apparatus, the computer device the start-up signal to start the motor, the solenoid valve is opened, the original display panel The data is cleared. After the motor drives the oil pump to pressurize, it is sent to the oil separator to separate the oil and gas. The gas is discharged into the atmosphere. The pressure oil enters the measuring transducer and is injected into the oil receiving container through the electromagnetic valve, the conductive rubber hose and the oil gun. At the same time, after the pressure oil is measured by the measuring transducer, the mechanical motion is replaced by the sensor with an electric pulse signal. If it is preset refueling, input the preset number from the keyboard first, and then raise the gun and add fuel. When the added quantity reaches the preset value, close the solenoid valve and the motor and stop the refueling.
 Â
2. When supplying power to the refueling tanker, ensure that the voltage is within the range of DC10V~DC30V so as not to damage the computer components by the peak voltage.
 Â
3, because the pump to the tanker is provided by the car, in order to ensure stable pressure, the car pipeline should be equipped with an overflow valve, if not, should be specified in the order, requiring the tanker with a relief valve to avoid damage Tanker.
 Â
4. When using the oil gun (oil dispenser automatic return reel), avoid using the oil gun's oil filling pipe to knock on the oil receiving container, press the switch and other incorrect operation, this operation may damage the root of the oil filling pipe and cause oil leakage. To check regularly, tighten the stop screw on the fill tube to prevent loosening or damage to the root of the fill tube.
 Â
5, the tank should be regularly cleaned to keep the oil clean.
6. The metering verification of fuel dispensers shall be conducted in accordance with the relevant provisions of JJG443-2006 "Measurement Regulations for Measurement of Fuel Refueler".
 Â
7. The filter is installed in front of the oil inlet of the tanker. Since the conditions of the oil products are not the same everywhere, the replacement cycle of the filter cannot be clearly defined; when the flow of the tanker suddenly decreases, replace the filter; if after the replacement, replace the filter; The traffic is still abnormal. Check whether other components affect the traffic. If the traffic is affected, replace the traffic.

Refueling vehicle users should be familiar with the use of fire extinguishers and inspect and maintain them in accordance with their instructions.
