Working principle of concrete pump

The first generation of pumping principle: electric control reversing technology, PLC control solenoid valve reversing to realize pumping and S-pipe distribution reversing.

The second generation pumping principle: hydraulic reversing technology, which completely relies on the change of hydraulic signals of master cylinder and distribution cylinder to realize action reversing.

Main structure: PLC electrical components, constant pressure pump, control box, nitrogen storage tank, water tank, pipe joint, control rod, cock, etc.

Features:

1, with anti-pumping function, which is conducive to timely troubleshooting of pipeline blockage and can stop for a short time.

2. It can automatically compensate the wear gap and has good sealing performance.

3. Wear-resistant alloy glasses plate and floating cutting ring are adopted, which has long service life.

4. Long-stroke cylinder prolongs the service life of cylinder and piston.

Precautions for use:

1, because the workability of concrete has a great influence on the conveying effect. In the process of construction, attention should be paid to accurate ingredients and moderate mixing, and segregation should not be caused by transportation and pouring.

2. Pumping concrete needs continuous operation, but some accidents will inevitably happen. This is the time to deal with the aftermath. For example, do a good job of radiation surface, reinforce the steel bar in insert link at the construction joint, and clean the template again without pouring concrete or brushing release agent.

3. Pumped concrete has great fluidity, so when pouring mass concrete, the requirements for formwork reinforcement are more stringent, especially in places where concrete appearance requirements are more stringent, such as bridge construction and tunnel lining construction.
