Three-cylinder piston pump is mainly used for acidizing, cementing, fracturing, sealing and other operations intermittent homework work. Three-cylinder piston pump has the following characteristics: 1. Three-cylinder piston pump reducer can be installed in 17 positions, making it suitable for different drive circuit pump unit. 2. Two different pump head body to fit the different size of the plunger (due to different pressure and displacement requirements). 3. Optional packing assembly, valve assembly, discharge flange, suction manifold, etc., to meet and meet the different layouts, different media, different environmental requirements. 4. Three-cylinder piston pump structure lightweight and simple, light weight, maximum displacement, maximum pressure.
Auxiliary Agent For Concrete Retarder
Classification by structure:
(1) Sugar: sugar calcium, gluconate, etc
(2) Citric acid, tartaric acid and their salts
(3) Zinc salt and phosphate
(4) lignosulfonate
Hardening effect
(1) Influence on strength, excessive incorporation will cause the concrete to remain unsolidified for 24 hours or even 72 hours, thus affecting the need for early strength of concrete and delaying the construction progress. No obvious effect was found on the concrete of suitable age.
(2) The effect on contraction, the appropriate use of the contraction has no significant effect. Excessive use will cause the top concrete to dry and shrink due to excessive water evaporation and shrinkage cracks.
(3) The effect on frost resistance durability is similar to that of concrete without adding retarder. [1]
