Intelligent water meter common fault causes and troubleshooting methods: Fault phenomenon cause Method of exclusion The clamping mechanism moves too slowly or the clamping force is too low 1. Water pressure is too low. 2. Two-position four-way clamp switch seal leak is too big. 3. Leakage of the seal in the clamping mechanism. 1. Water pressure must be 2.5-4MPa. 2. Replace the two-position four-way clamp switch seal (usually two "O" rings on the valve stem). 3. Replace the seal again. Gauge drain valve leak 1. Drain valve cone rubber cover variant or foreign body. 2. The drain valve seal wears. 3. Two-position four-way drain switch seal Worn circle. 1. Replace the tapered rubber cover or remove foreign objects. 2. Replace the seal of the drain valve. 3. Replace the two-position four-way drain switch seal (usually two "O" rings on the valve stem). Solenoid valve does not move 1. Solenoid valve power cable connector loosen 2. Solenoid valve coil open circuit 1. Check the power cord reconnect 2. Replace solenoid valve coil Can't beat 1, hydraulic pump seal leakage 2, pipeline leakage 3. There is air in the tube 1, replace the seal ring 2, replace the seal ring 3, pressure booster handle turn left and right several times Plastic Fruit Box Making Machines
Meticulous division of labour, consecutive processes, professional of manufacture and high standard equipment ensure the high quality of the machine.
Factory introduced high precision maching tools, with the equipment of cutting machine tools, heattreating facilities, check out test sets and painting facilities, the processing ability for middle and large size machine, reach a high level in plastic industry while the quality if the machine is ensured at the same time.
All kinds of fruit and vegetables containers can be designed and produced by this machine.
All production line can be provided.
Vertification of many year's market application, optimal combination configuration, stable, reliable and durable system with the characteristics of high efficiency, energy saving, low voice and strong power.
The strengthening design of template is carried out through multiple times of optimization design of major components such as template, based on the analysis of finite element software, which both guarantee the lifetime of template and protected mould.
High rigid template adopts the structure with coexistence of installation screw hole and T-shaped groove.
The tie rod of each machine model has passed the test by professional testing organization, which means that, the deflection of tie rod is within reasonable scope while guaranteeing the operation of machine.

Intelligent water meter installation and common faults
Smart meter installation requirements:
1. In order to ensure the most accurate measurement, install a straight pipe section with at least 5 times the surface diameter of the pipeline and the same section in front of the water meter inlet, and install at least 2 times the straight pipe section of the water meter outlet at least.
2. The connecting pipes at the upstream and downstream of the water meter cannot be reduced in diameter;
3. It is recommended to install flow control equipment (such as valves) and filter equipment;
4. The flange sealing ring must not protrude into the pipe or be misaligned;
5, must be thoroughly cleaned before installing the water meter to avoid damage to the water meter debris;
6. The flow direction of the water meter should be the same as the flow direction of the pipeline;
7. After the water meter is installed, slowly discharge water to fill the pipeline to prevent the high-speed air flow from crashing the meter.
8, the installation location should ensure that the pipeline is full of water, air bubbles will not be concentrated in the table, should avoid the water meter installed in the highest point of the pipeline;
9. Water meters should be protected from water pressure shocks;
10. Small-caliber rotor-type water meters must be installed horizontally. Tilting forward and backward or left and right will result in reduced sensitivity.
