Why more and more people choose rail lifts

Rail-type elevators are mainly used for transporting goods between various working layers. However, when they are used, there will be a slow rise. When the equipment is working, it is mainly a hydraulic pump that uses hydraulic motors to drive. What causes the slowness? Rail lift

1. The hydraulic system pressure should be checked only when the hydraulic rail type ascends and descends the freight elevator with load and can not start working. If the pressure is lower than the normal range, the capacity can be adjusted to set the relief valve.

2. The hydraulic oil has deteriorated or has impurities. After the hydraulic oil is used for a long time, there may be impurities or deterioration in the hydraulic oil. Sampling and inspection should be carried out to see if it contains solid particles, discoloration and odor. If it is indispensable, it should be changed to hydraulic oil. Rail lifting machine

3. There may be congestion in the hydraulic lines. The hydraulic line is also a very tight link to check whether the hydraulic line is smooth. Zhenyang rise and fall machine prompts everyone to focus on whether the hydraulic valves cover one-way shut-off valves, electromagnetic reversing valves, proportional control valves, relief valves, etc., whether there is congestion or jam. If there is a problem, the hydraulic valve should be cleaned or changed as soon as possible. Rail lifting machine

4. There may be leakage in the hydraulic system . Investigate whether there is leakage in the hydraulic system, and focus on checking the joints of hydraulic pipes and joints, cylinders and hydraulic valves. If the leakage of hydraulic oil is revealed, change the composite mat or disturb the raw material belt.

5. The hydraulic pump is also a key factor affecting the flow of hydraulic oil. If the hydraulic pump is used for a long time, it is easy to reveal the problem. When the hydraulic pressure rises and falls, the platform speed is slowed down, it should be checked whether the hydraulic pump oil supply flow is stable. If you find that the problem is early combined with the manufacturer, you will not be covered.

6. It is not possible to debug the relief valve by yourself. Rail lifting machine

The reason for the slow occurrence of the rail-type elevators is mainly caused by the later man-made, so it is very important to carry out maintenance and maintenance work when used normally, thereby reducing the occurrence of accidents and improving work efficiency.

1. The rise and fall speed of the hydraulic rail type ascending and descending freight elevator is slowed down, and the overflow valve is self-tuned. After the relief valve is commissioned, the speed is not increased, and the reverse rail-type ascending and descending freight elevator reveals the fault stop operation. Rail lifting machine

2. After the installation of the facility, the use of hydraulic rail-type ascending and descending freight elevators caused by the use of inappropriate or aging and dirt has slowed down. After the speed is slowed down, first consider the factors of the problem hydraulic oil flow. Factors affecting hydraulic oil flow are: hydraulic lines, hydraulic valves, hydraulic oil pumps, motor speed control devices, etc. Rail lifting machine

3. The relief valve is normally placed inside the pump station and has a commissioning valve on one side. Its utility is to avoid excessive pressure in the hydraulic system and to take care of the hydraulic system settings. It is dangerous to set up the relief valve innocently. If the pressure in the cylinder or oil pipe is too large, it is likely to reveal a serious fault of blasting. The rail elevator customer stopped the operation due to the self-tuning of the relief valve.
