致动缸的缸体及其制造方法和混凝土泵送设备
摘要：
本发明公开了一种致动缸的缸体，该缸体包括内衬层（1）和结合在该内衬层（1）的外部的第一纤维复合材料层（2），所述第一纤维复合材料层（2）由第一纤维材料和基体树脂复合而成，并且所述基体树脂为聚氨酯。还公开了一种具有上述致动缸的缸体的混凝土泵送设备。还公开了一种致动缸的缸体的制造方法，该方法包括：形成内衬层步骤：形成内衬层（1）；以及结合步骤：采用第一纤维材料和基体树脂形成第一纤维复合材料层（2）并将该第一纤维复合材料层（2）结合到所述内衬层（1）的外部，并且所述基体树脂为聚氨酯。上述致动缸的缸体不仅强度较大、重量较轻、耐疲劳性和耐腐蚀性较好，而且在作业过程中不易受到损伤，使用性能较好。
摘要（英）：

The invention discloses a cylinder body of an actuating cylinder. The cylinder body comprises an inside liner (1) and a first fiber composite layer (2) combined outside the inside liner (1), wherein the first fiber composite layer (2) is compounded by a first fiber material and matrix resin, and the matrix resin is polyurethane. The invention also discloses concrete pumping equipment with the cylinder body of the actuating cylinder. The invention further discloses a manufacturing method of the cylinder body of the actuating cylinder. The manufacturing method comprises the following steps of: forming the inside liner (1); and combining: forming the first fiber composite layer (2) from the first fiber material and the matrix resin, and combining the first fiber composite layer (2) to the outside of the inside liner (1), wherein the matrix resin is the polyurethane. The cylinder body of the actuating cylinder is larger in strength, higher in weight, better in fatigue resistance and corrosion resistance, not easy to damage in the operation process and better in using performance.
