As a special vehicle for the industry, a refrigerated truck should pay special attention to its daily maintenance, delay its service life, and better play its cooling and preservation role. Therefore, before driving, a thorough inspection must be conducted to prevent unnecessary troubles during the journey. Each time the goods are loaded, the following items must be carefully inspected:
1. The refrigerated vehicle fuel diesel or gasoline must be sufficient to ensure that the engine runs at least to the next inspection point.
2. The refrigerated car engine oil level should be at the full mark, do not over-fuel and change once a year.
3. The refrigerated truck should check the coolant level gauge to see if the coolant volume is within the specified range, and the pointer should be within the white range. If the coolant level is in the red range, add coolant to the coolant tank.
4. The battery terminal of the refrigerated truck must be firm and non-corrosive. The electrolyte should be at the full mark.
5. Belt straps must be well adjusted and adjusted to the appropriate degree of swell. The 13mm sag across the center between the pulleys. 6. Check all electrical connections in the electrical control circuit to ensure that they are secure and do not corrode.
7. Visually inspect the unit for leaks, loose parts, or breakage or damage.
8. Gaskets The washers installed in the unit should be firmly clamped.
9. Refrigerated car coil condenser and evaporator coil should be clean and free of dirt.
10. Defrost Drain Check the defrost drain hoses and fittings to ensure they are clear.
11. The cargo cannot cover the outlet and back of the evaporator when the cargo compartment is loaded to ensure that the cold air circulation in the cargo compartment is smooth and there is no hot spot.
All maintenance and dismantling of refrigerated truck equipment must be carried out at the repair station. Pay attention to safety when performing repairs or disassembly work, and prevent accidents such as bruising or bruising caused by the use of tools or improper use of tools. Make sure that the diesel engine is always in a clean and sound condition. Before disassembling the parts, clean the parts or wipe them clean before assembling the parts to ensure that the parts are tidy and ensure assembly quality. More complicated maintenance adjustments should be carried out in the service station to prevent the pollution of the diesel environment!
Ultrasonic water meter is a new type of water flow meter, by detecting the ultrasonic beam propagation in the water and tide by speed changes generated, which analyze and process water flow rate. Ultrasonic water meter is the use of ultrasonic time difference principle, the use of industrial grade.
Ultrasonic Water Meters have the following features: low initial flow rate, wider measuring range, higher measuring accuracy, good stability and no need to set parameters installed at any angle. No moving parts inside the unimpeded flow element, is not affected by impurities in the water, and long service life.
The ultrasonic Water Meters have excellent low flow detection capabilities, which can solve the problem of many traditional water meters, more suitable for water gradient charge, more for conservation and rational use of water resources and have broad market prospects and use,is a good product to as Home Water Meter.
