The hydraulic baler is equipped with an electrical self-locking circuit, which can protect the motor from overload, short circuit, voltage loss, and undervoltage.
1. Overload protection: The thermal relay is mainly used to protect the asynchronous motor from overload. Its working principle is that after the overload current passes through the thermal element, the bimetal is heated and bent to push the action mechanism to drive the contact action, thereby controlling the motor circuit Disconnect, realize the motor power off and stop, play the role of overload protection.

2. Short circuit protection: The air switch is a switch that trips as long as there is a short circuit and the switch forms a loop.

3. The principle of the air switch is that when the line is short-circuited or severely overloaded, the short-circuit current exceeds the instantaneous tripping setting current value, and the electromagnetic tripping device generates enough suction force to attract the armature and hit the lever to make the hook around the shaft seat Rotate upwards to release the lock, and the lock breaks the three main contacts under the action of the reaction spring to cut off the power supply.

4. Loss of voltage protection Undervoltage protection: The coil of the contactor is generally connected in parallel with the electrical equipment. If there is a voltage loss or undervoltage, the electrical equipment will be burnt due to lack of phase, and the contactor has loss of voltage and undervoltage During protection, if the voltage is not enough or the phase is missing, the contactor will trip and use electrical equipment to disconnect. So as to protect the electrical equipment from burning due to lack of phase or undervoltage.

Therefore, the electrical self-locking circuit of the hydraulic baler is particularly important and requires key protection.

Nick brand hydraulic baler is safe and reliable, low power consumption, economical and reasonable, convenient to use, simple to maintain and operate. It is a good helper for your production.

The work of the hydraulic system is reliable, but some failures may occur due to poor maintenance, damage to hydraulic components or unreasonable design, improper assembly adjustments, etc. during use and the test of new hydraulic equipment.

In the hydraulic system, most of the mechanisms and oils of various hydraulic components and auxiliary devices are in the enclosed shell and pipeline, which cannot be directly observed from the outside. It is not as clear as the mechanical rotation, and it is not as good as the measurement and pipeline connection. The circuit is so convenient, so it often takes more time to find the cause when a fault occurs.

When the hydraulic baler is used, some of these failures of the hydraulic system are caused by the failure of a certain hydraulic system component, some are caused by the comprehensive factors of multiple hydraulic components in the hydraulic system; some are caused by hydraulic oil pollution, even if the same A failure phenomenon, the cause of the failure is also different, especially the current hydraulic equipment, which is a common combination of mechanical, hydraulic, electrical, and even microcomputers, and the resulting failures are manifold.
Therefore, Nick Machinery reminds you: After a hydraulic failure occurs, the hydraulic system of the hydraulic baler must be diagnosed to determine the location of the hydraulic equipment failure and the nature and cause of the failure, and take corresponding measures to ensure the normal operation of the equipment.

Nick brand waste paper baler is easy to operate, safe and energy saving, it is your best helper
The last article talked about what the gear pump of the waste paper baler is. Now Nick Machinery will tell you the precautions for the installation of the gear pump.
1. When replacing and installing the gear pump of the waste paper baler, first distinguish the direction of the oil inlet and outlet of the oil pump, and it cannot be installed reversely. The center height and concentricity of the main shaft of the transmission motor (or internal combustion engine) and the oil pump should be the same, and the installation deviation should not be greater than 0.1mm. At the same time, there should be an axial gap at the shaft ends to prevent collisions during axial movement. Generally, flexible couplings should be used.

2. The installation position of the pump relative to the height of the fuel tank should not exceed the specified oil suction height, generally should be less than 0.5m. The suction pipe of the pump should not leak air. The suction pipe should not be too long or too thin, and the elbow should not be too many.

3. The viscosity and oil temperature of the hydraulic oil of the waste paper baler system should be selected according to the brand specified in the sample or regulations. The working oil temperature is generally around 40 degrees.
4. When the oil pump is started, start it with no load for several times. If the air is not drained, the pump will produce vibration and noise. At this time, the connection of the oil outlet should be slightly loosened, so that the gas in the pump is completely removed and the movement is stable. Then, slowly load and run from no-load until it is stable before it can be put into normal operation.
5. After the hydraulic oil pump of the waste paper baler enters into work, it is necessary to check the operation of the pump frequently. If any abnormality is found, the cause should be found out immediately and the fault is eliminated.

The working oil of the gear pump should also be checked regularly, and the hydraulic oil of the waste paper baler is usually tested every 3 months.

The Nick brand hydraulic baler is recognized by many customers with its high-quality qualifications and professional craftsmanship according to everyone's actual needs and is trustworthy.
In today's society, people have a deeper and deeper understanding of noise, and it is imperative to reduce the noise of hydraulic equipment. The hydraulic pump is one of the main noise sources of hydraulic equipment. The research on the noise fundamentals of hydraulic pumps has attracted wide attention at home and abroad.
The noise of hydraulic pumps can be divided into three aspects: hydraulic noise, mechanical vibration noise, and liquid-gas mixed noise. What is the cause of sudden noise in the plunger pump during use?
1. The inherent noise of hydraulic plunger pumps
2. Cavitation noise
3. Mechanical noise
4. Sudden noise
5. The noise generated by the hydraulic plunger pump after maintenance
6. The hydraulic plunger pump makes noise after replacing the hydraulic oil

7. Gradual noise

These seven aspects are the source of noise generated by the plunger pump of the hydraulic baler, and the maintenance personnel can repair it after confirming the cause of the noise.

The machine has been running for a long time, and there will always be various faults. Many people don’t know how to solve it. Our maintenance personnel at Nick Machinery, combined with their years of maintenance experience, put forward a set of query techniques to determine the specifics. Where is the problem?
1. Ask the equipment operator to understand the operating status of the equipment.
2. Ask whether the hydraulic pump is abnormal.
