Repair method for poor operation of hydraulic motor of concrete transport vehicle

Release date: 2019-04-23 Article source: Zhengzhou Changli Construction Machinery

The operation of the concrete mixing plant breakdown vehicle is as follows:

Two methods:

1. Set the oil pump operation handle to the "neutral" position and stop the engine.

2. Remove the original high-pressure hose and oil return pipe from the motor, and connect the high-pressure hose and oil return pipe for rescue. Pay attention to plugging the original high-pressure hose to prevent oil leakage from the high-pressure hose.

The operation of the rescue vehicle is as follows:

1. Set the oil pump operation handle to the "neutral" position and stop the engine.

2. Remove the original high-pressure hose and the return pipe from the oil pump, and plug it with a pipe to prevent oil leakage from the oil pipe. At the same time, connect the high-pressure hose and the return pipe for rescue to the oil pump.

3. Start the engine. (At this time, ensure that the hydraulic oil in the fuel tank of the rescue vehicle is sufficient)

4. Set the operation handle to the "reverse discharge" position, so that the concrete inside the car is discharged.

After the emergency rescue was completed, the two cars were restored to their original state.

Two methods:

Open the cover of the mixing tank inspection hole, unscrew the pipe joint of the high-pressure hose, make the inspection hole of the mixing cylinder downward, and discharge the concrete from the inspection hole of the mixing cylinder.

Second, the method that can be used when the hydraulic motor fails:

a way:

1. Remove the hydraulic motor of the rescue vehicle and install it on the faulty vehicle. At the same time, connect the high-pressure hose and oil return pipe for rescue to the fuel pump of the rescue vehicle and the newly installed motor of the faulty vehicle. Put it in the "reverse discharge" position to make the concrete inside the car discharged. After the emergency rescue, the two vehicles were restored to their original state.

2. Replace with a new hydraulic motor to return the mixer to normal operation.

Two methods:

Open the cover of the mixing tank inspection hole, unscrew the pipe joint of the high-pressure hose, make the inspection hole of the mixing cylinder downward, and discharge the concrete from the inspection hole of the mixing cylinder.

Note: When loosening the high-pressure pipe joint, the mixing drum often rotates quickly. Therefore, before operation, put a wooden wedge between the mixing drum and the mixing drum track to prevent the mixing drum from rotating.

Questions and answers about concrete machinery and equipment

Question: What equipment are included in the general configuration of HZS60 concrete mixing station?

Answer: The standard configuration is: one JS1000 mainframe, one frame, one PLS1600 four-bin separate metering and batching machine, one water metering, one cement metering, one additive metering, fly ash metering, 100T powder tank Two, two sets of LSY273 * 8M delivery pumps, one set of pneumatic system and one set of fully automatic computer control system.

Q: What is the price of JDC350 concrete mixer? I do n’t use much

Answer: This type of mixer is mostly used in temporary construction sites, prefabricated parts factories, and the amount of concrete is not a special item. A JDC350 is generally sold below 25,000.

Question: What is the net floor area of HZS90 concrete mixing station equipment?

Answer: If the device is placed in a linear pattern, the approximate area (length × width) is: 53 meters × 13 meters.

Question: How much does it cost to invest in the equipment of the HZS180 concrete mixing plant production line?

Answer: A: This type of mixing station is a medium-sized mixing station. Different manufacturers and different configuration requirements will cause the equipment input price to fluctuate. Reasonable price, I think it should be around 1.8 million.

Q: How is the treatment of the concrete mixing station? Want to go to work

Answer: The income situation of different posts at the mixing station is obviously different. This depends on the ability.

Q: What is the reason for the non-operation of the electric actuator? How to eliminate it?

Answers: (1) Overload (2) Limit switch in the junction box (3) The push rod reaches the limit position

Remove the mechanical overload fault and reset the limit switch; replace the limit switch with a new one; remove and loosen the nut.

Question: How to choose the batching machine of HZS120 concrete mixing station?

Answer: At present, according to industry standards, the sand and stone batching machine used at the HZS120 station basically uses a PLS3200 four-bin batching batching machine. However, it is recommended that users choose equipment from large manufacturers with the scale and strength. There is a guarantee that no one wants to be small and cheap, affecting the daily production of their own mixing station.

Question: Which is better for HZS60 concrete mixing plant? Reliable manufacturers with guaranteed product quality

A: At present, there are many professional manufacturers of concrete mixing equipment in China, such as well-known domestic manufacturers: Sany, 28 Group, Zhengzhou Changli, Changli Construction Machinery, Shan Dongfangyuan, etc.

Question: How to install HZS120 concrete mixing station?

Answer: I don't recommend users to install this type of mixing station by themselves. Generally speaking, the manufacturer of the equipment should arrange technicians to guide the installation and commissioning at the user's site.

Choose the right type of forced mixer according to your own needs. Different concrete mixers choose different types of concrete mixers. It is also a principle to purchase mixers based on production and demand.

Good authentic service, fast production speed and high efficiency of the factory.

Friends from Xiushan County

The appearance of the concrete mixer is also very important. The first is the quality of the appearance. If the quality of the appearance is good, the wear resistance of the concrete mixer will be better.
