Earth pumpIt is a construction equipment that relies on pressure to convey concrete through pipelines. It is equipped with special pipes, which can continuously carry out horizontal and vertical transportation along concrete pipes. It is an ideal one in existing concrete conveying equipment. It combines the production of ready mixed concrete with pumping construction, and uses concrete mixing truck to carry out intermediate operation, so that concrete connections can be realized.Continue pumping and pouring.It is used for conveying concrete in large concrete projects.
Effect of cleanliness on performance of ground pump:
During construction, the dust on the site is very large, and the wind blows in the sun. It is still in continuous use.天天看高清影视官网
trucks will inevitably have maintenance costs.How much cleanliness of concrete pump truck has on performance?
If the concrete pump truck does not clean the concrete in time, it will cause the gearbox, reducer, hydraulic oil tank, hydraulic radiator, main valve and other important components to be covered by concrete, thus affecting various properties.
When the concrete pump truck works, the power will generate partial high temperature and high pressure, and the thermal conductivity of the equipment needs heat dissipation.If the concrete blocks are not cleaned in time, the thermal conductivity of these components will be affected.
The gearbox will produce water vapor in the course of work.When a large amount of gas is collected, the internal pressure rises.There is a vent at the top of the gearbox.The ventilation holes are one-way valves.Under normal circumstances, the valve is closed and the internal pressure remains unchanged.When rising, stop check valve to stop steam.
Inspection of ground pump products:
(1) fuel, lubricating oil, hydraulic oil and water tank are all added. Tire pressure meets the requirements, and lighting and signal indicators are well equipped.
(2) the hydraulic system works normally, the pipeline has no leakage; the washing pump is well equipped.
(3) there is no sundries in the mixing drum, and the protection net on the hopper is intact.
(4) the transmission line is firmly connected and sealed.
Pipes and hoses for cloth arms shall be selected according to the requirements of the factory manual.No pipe shall be used in excess of specified diameter.The hose to be connected should be fixed on the seat belt.
The boom should be arranged in the order specified by the factory.When the boom is lifted from the support, it can swing.Do not use arm lever to lift or drag objects.
Do not move the body when the boom is fully stretched.When moving the body, you should fold and fix the upper arm. The speed should not exceed 10km / h.
Do not pull the hose on the front end of the boom to the ground; do not extend the fabric pipes and suspender.When the wind force reaches 6 or above, the boom should not be used to convey concrete.
(1) the horizontal pump tube should be buried in a straight line.
(2) the vertical pump shall not be directly installed on the output port of the pump.The vertical pipe should be installed at the front end of the horizontal pipe not less than 20m, and the check valve should be installed on the pump near the horizontal pipe.
(3) when the inclined pipe is laid, the horizontal pipe should be installed at the outlet, and its length should not be less than 5 times of the height of the inclined pipe.When the inclination is large, the exhaust valve should be installed at the upper end of the slope.
(4) pump piping should be supported and fixed.Wooden pads should be provided between pipes and fixed objects for cushioning.It shall not be directly connected with steel bars or formwork.The pipes and pipes should be firmly connected; the joints and clamps should be tightened and sealed.No leakage is allowed; worn pipes must not be installed in the high pressure area at the rear end.
(5) pressure test should be carried out after laying the pump pipe.
