1. The pressure of the measured medium is large;
2. The installation position of the pressure gauge is large.

Second, the seismic pressure gauge has no indication:

1. The shut-off valve on the pressure guiding tube is not open;

2. The pressure guiding tube is blocked;

3. The dirt in the spring pipe joint is too much and blocked;

4, the spring tube splits;

5. The center tooth and the fan tooth wear too much, so that it cannot be engaged.

Third, the seismic pressure gauge pressure indication error is uneven:

1. The spring tube deformation is invalid;

2. The free end of the spring tube and the sector gear, the gear ratio of the connecting rod is improperly adjusted.

Fourth, the shock gauge pointer has a beating or sluggish phenomenon:

1. The pointer touches the surface glass or the scale to have a friction;

2. The center gear shaft is bent;

3. The two gears are meshed with dirt;

4. The movable screw between the connecting rod and the fan gear is not flexible.

5. After the pressure of the seismic pressure gauge is removed, the pointer cannot be restored to zero:

1, the pointer is bent;

2, short hair loss is insufficient;

3, the pointer is loose;

4. The transmission gear has a friction.

Sixth, the transmission ratio is out of adjustment.

7. The indication of the seismic pressure gauge is low:

1. Gear ratio imbalance;

2. The spring tube has leakage;

3. The pointer or the transmission mechanism has a friction;

4. The pressure guiding pipeline is leaking.

8. The shock gauge pointer cannot indicate the upper limit scale:

1. The transmission ratio is small;

2. The movement is fixed at the position of the machine base;

3. The spring tube is not properly welded.

Steel Wire Take-up Machine

A.The input power supply is three-phase 380V50HZ. The voltage waveform is sinusoidal, and the amplitude fluctuation is not greater than+5~- 10%.

LZ600 wire drawing machine

1. 1 Professional and technical personnel are required to carry out installation and commissioning. Before use, it is necessary to carefully read this manual and the relevant electrical instructions provided.

1. 2 Each machine and electric control cabinet shall be reliably grounded with a grounding resistance not more than 4Ω.

1. 3 There should be no accumulated water on the table top, especially near the operation box, as it can easily lead to circuit failure due to water infiltration.

1.4 It is prohibited for multiple people to operate the same equipment at the same time to avoid accidents.

1. 5 The electric control cabinet should be placed in a clean and dry room, and the door should be closed when working to prevent dust intrusion from causing device performance degradation or failure. Air conditioning is used to maintain the ambient temperature of the electric control cabinet. Frequently check the operation of the cooling fan on the top of the electric control cabinet.

1. 6 Before starting the machine, check whether the safety device is normal.

1. 7 Do not operate the components in the electrical cabinet with power. After cutting off the main power supply, wait at least five minutes, and wait until the intermediate circuit capacitance is discharged before operating the frequency converter, motor, or motor cable.

1.8 Do not touch the IC circuits on the inverter control interface board and motor control board, as static electricity may damage these circuits.

1.9 Please provide the power supply and operating environment according to the technical requirements of Section 3.2. It is not allowed to arbitrarily change the parameters of the frequency converter and PLC. The user shall be responsible for any damage to electrical components caused by human factors.

The second Delivery inspection

2. 1. Check whether the equipment is damaged and complete upon delivery (according to the packing list). If there is any damage or inconsistency with the contract, please contact the dealer or manufacturer immediately.

2. 2 The manufacturer is only responsible for quality issues arising during production, and is not responsible for damage caused during unpacking, improper installation and use, or damage caused by overload operation.

2. 3 After unpacking, the accompanying documents should be properly kept, as they are necessary during equipment installation, commissioning, and use.
