Haomei concrete pump how to achieve the goal of large displacement, high lift

Haomei concrete pump how to achieve the goal of large displacement, high lift
Concrete pump concrete pump pipe inner surface quenching equipment, heat treatment process, concrete pump pipe is made of special material steel tube, through inner surface hardening, infiltration of carbon processing, flange bushings hardness of 58 and 60 degrees, the pipe service life is 3-5 times, the user saves time and cost, removes often in for trouble, improve the production efficiency.No hardening of concrete pump pipe and hardening of concrete pump pipe its performance and life are not the same, after hardening of concrete pump pipe can be transmitted more nearly thousands of cubic meters of concrete.According to the directional button several times, check the pressure of the accumulator value (see numerical value on pump certificate). When the hydraulic oil temperature over 90 ℃, the oil temperature sensor connected, indicator, relay action, power of electromagnetic valve, the pump automatically stops.When the diesel engine oil pressure is lower than 0.04 MPa, indicator, relay...

Concrete pump tube four considerations

Concrete pump tube four considerations
H aomei   remind you when the concrete pump tube shall be carried out according to its technical parameters and specific situation, here we introduce for everybody four precautions: concrete pump tube A, vertical tube 1. The vertical tube, to reduce concrete pump outlet pressure, appropriate ground horizontal tube length is not less than a quarter of the vertical tube length, usually should not be less than 15 meters.Such as constraints can increase the bend or circular tube meet the demand. 2. When the vertical conveying distance, should be in a concrete pump machine Y tube discharging mouth 3-5 metres of conveying pipe root set pin valve to prevent concrete mixture reflux. Second, the down side tube 1. The down side cloth tube, when the elevation difference is greater than 20 meters, should be in the lower inclined tube set 5 times the length of the elevation difference of horizontal tube;Such as constraints, can increase the bend or annular pipe to meet the requirements of elevation difference length of 5 times. 2. When the slope is greater than 20 째, should first open the discharge valve, stay under the pipeline section concrete with a certain pressure, can close the discharge valve. Third, summer construction Hot season construction, should be cover with a damp cloth and straw bag to cover the conveying pipe, in order to avoid direct sunlight, tube concrete slump loss, transportation difficulties. Fourth, winter construction Cold season construction, appropriate USES heat preservation material in the conveying pipe, prevent concrete seas, and guarantee the concrete into the mold temperature. Above is the concrete pump tube four considerations.
