A concrete pump is a kind of construction equipment commonly used by construction parties. It can greatly improve the efficiency of construction and is deeply welcomed by construction parties. However, in order to prolong the service life of the concrete pump, it is very important to maintain certain concrete pump maintenance skills.

So how should the maintenance of the concrete pump be carried out?

Specifically, we can start from the following aspects.

1. Hydraulic oil

Hydraulic oil is a working medium that requires a high degree of cleanliness. The upper cover of the hydraulic oil tank cannot be opened casually, so as to prevent impurities from mixing into the hydraulic oil. It should be reminded that the hydraulic oil should be replaced after 300 hours of work for the first time, and the hydraulic oil should be replaced every 600 hours after the work.

2. Thermometer

Under normal circumstances, the thermometer usually displays the oil temperature of the hydraulic oil, and the normal working temperature of the hydraulic oil is generally 30℃-60℃, and the highest oil temperature generally does not exceed 70℃.

3. Oil level gauge

The oil level gauge can generally be used to observe the amount of oil in the oil tank. Usually, the oil level of the oil level gauge must be located above the specified scale during operation. If it is missing, add hydraulic oil immediately.

4. Drain valve

The use of drain valve can generally be used to open the tank when cleaning, usually, the drain valve is closed. The drain valve can be opened once a week after 24 hours of the shutdown to remove the water deposited at the bottom of the fuel tank.

5. Air filter (on the hydraulic oil tank)

The air filter can prevent foreign debris from mixing in and filtering the air, and it is recommended to replace it every six months.

6. High-pressure oil filter (one for the main system and one for boom system)

When the prismatic pointer on the oil filter points to the green mark, it means that the work is normal and the filter element is not blocked; when the pointer points to the yellow color mark, it means that the filter element is blocked, but it can continue to work; when the pointer points to the red mark, indicating that the filter element is seriously blocked and cannot continue to work, and the filter element must be replaced immediately, and the filter element should be replaced at the same time every time the hydraulic oil is replaced.

7. Fastening elements

Before starting the machine every day, check whether the fasteners are loose. If they are loose, they should be tightened before proceeding to the next step.

8. Cylinder seals

Cylinder seals should be replaced every 1000 hours of operation.

9. Electrical components

Before starting the machine every day, check whether the electrical components and connections are abnormally loose.9. Electrical components

10. Swing valve cylinder ball head and upper and lower spherical bearings

The ball head of the swing valve cylinder and the upper and lower spherical bearings should be checked once every 500 hours of operation, and if the wear is serious, it should be replaced in time.

A concrete pump is a kind of construction equipment commonly used by many construction parties at present. Good maintenance of concrete pumps in daily life can prolong their service life. Through the above introduction, I believe that the majority of users have already understood the maintenance skills of concrete pumps.
