1、自動上料混凝土攪拌車液壓缸裝配時端蓋裝偏,活塞桿和缸筒不同心,導致活塞桿伸出困難,加速密封件磨損??梢圆痖_檢查,重新裝配。
1. When the hydraulic cylinder of automatic feeding concrete mixer is assembled, the end cover is biased, and the piston rod and cylinder are not concentric, which makes it difficult for the piston rod to extend and accelerates the wear of the seal. It can be disassembled for inspection and reassembled.
2、密封件安裝差錯:例如密封件裝錯或漏裝。
2. Seal installation error: for example, the seal is installed wrong or missing.
①密封壓蓋未裝好,不能壓緊:如壓蓋安裝有偏差、緊固螺釘受力 不均、緊固螺釘過長等。應該按對角順序擰緊各螺釘,擰緊各螺釘時要受力均勻一致,按找螺孔深度合理選配螺釘長度。
① If the gland is not installed properly, it cannot be pressed tightly: for example, the gland is installed with deviation, the fastening screw is stressed unevenly, and the fastening screw is too long. The screws should be tightened in diagonal order, the force should be uniform when tightening the screws, and the screw length should be selected according to the depth of the screw hole.
②査密封件質量是否有問題:當反復更換新密封圈均解決不了 漏油問題時可能屬于這種情況。此時應確認密封圈是否購自非正規廠家的產品,密封材質尺寸是否有問題密封件是否保管不善自然老化 變質。
② Check whether there is a problem with the quality of the seal: this may be the case when the oil leakage can not be solved by repeatedly replacing the new seal ring. At this time, it should be confirmed whether the seal ring is purchased from the irregular manufacturer's products, whether there is a problem with the size of the seal material, and whether the seal is not properly kept and naturally aged.

③查密封部位的加工質量是否符合要求:如溝槽尺寸及精度不 符合要求、密封表面粗糙、未倒角等,應按有關標準設計加工溝槽尺寸,不符合要求的要修正到要求的尺寸,修正并去毛刺。
③ Check whether the processing quality of the sealing part meets the requirements: if the groove size and accuracy do not meet the requirements, the sealing surface is rough, and there is no chamfer, the groove size shall be designed and processed according to the relevant standards. If the groove size does not meet the requirements, it shall be corrected to the required size, corrected and deburred.
④查自動上料混凝土攪拌車液壓缸密封件的使用條件:如油不清潔、黏度過低、油溫過高、周圍環境溫度太高等,分別采取更換適宜的干凈油液、査明溫升原因,采取隔熱、設置油冷卻裝置等措施。
④ Check the service conditions of the hydraulic cylinder seal of the automatic feeding concrete mixer: if the oil is not clean, the viscosity is too low, the oil temperature is too high, and the ambient temperature is too high, the appropriate clean oil shall be replaced, the cause of temperature rise shall be found out, and the measures such as heat insulation and oil cooling device shall be taken.
3、選擇液壓油缸的時侯,根據實際需要,在滿足內徑、行程、使用壓力和安裝形式的基本要求后,還應特別注意:
3. When selecting the hydraulic cylinder, according to the actual needs, after meeting the basic requirements of inner diameter, stroke, service pressure and installation form, special attention should be paid to:
①液壓油缸承受負載后,如果其輸出速度達到一定的標準,為了減少液壓缸高速運動中忽然停止所產生的液壓沖擊,則必須選用帶有緩沖裝置的液壓缸;速度更高的,還需在液壓缸外加減速閥。
① If the output speed of the hydraulic cylinder reaches a certain standard after bearing the load, the hydraulic cylinder with buffer device must be selected in order to reduce the hydraulic shock caused by the sudden stop in the high-speed movement of the hydraulic cylinder; Higher speed, but also in the hydraulic cylinder speed valve.
②對于行程超過lOOOmm的液壓缸,為了防止活塞桿過載及活塞過快磨損,應該使用支撐環。
② For the hydraulic cylinder with stroke more than 100 mm, in order to prevent overload of piston rod and rapid wear of piston, support ring should be used.
③一般來說,不同的液壓油適用于不同材質的油封,選擇液壓油或油封時應注意密封材料與液壓油和工作溫度的關系,從而保障自動上料混凝土攪拌車液壓缸的壽命。
③ Generally speaking, different hydraulic oils are suitable for oil seals of different materials. When selecting hydraulic oil or oil seal, attention should be paid to the relationship between sealing material, hydraulic oil and working temperature, so as to ensure the service life of hydraulic cylinder of automatic feeding concrete mixer.
