Axial piston pump ka working principle

④ Cylinder bore and plunger pair Ukuze ugweme ukuhlanganiswa kwengcindezi, umphetho we-cylinder bore kufanele uhlanzwe futhi ube nekhono; ukuze wandise impilo yesevisi ye-cylinder, ezinye ze-piston bore zifakwe i-wear-resistant alloy cylinder liner (Fig. f), kanti ezinye zifakwe i-wear-resistant layer ngokusinyathelisa noma ezinye izindlela; ukuze kuncishiswe amandla aseduze, ubuso be-piston bukhululekile ukuvula i-annular groove [Fig. g (a)], kodwa manje kubonakala kulula ukuholela ekubanjweni kwe-plunger, ngakho-ke i-plunger elula ivamise ukusetshenziswa njengamanje. Ukuze kuncishiswe isisindo, kuncishiswe amandla e-inertia kanye ne-centrifugal force, futhi kuthuthukiswe izici zokunyakaza ze-pump, i-plunger ivamise ukwenziwa ibe ifomu elingenalutho elinokwakheka okulula. Nokho, i-hollow cylinder ikhulisa ivolumu engasebenzi "efile" ebhakedeni le-cylinder, okungasizi ekuthuthukiseni ukusebenza kwe-volumetric nasekunciphiseni umsindo, ngakho-ke ivamise ukugcwaliswa ngensimbi elula noma ipulasitiki elula [Fig. g (b)].

此外，为了减少活塞与气缸孔之间环形间隙的泄漏，活塞孔的间隙通常控制在0.02 ~ 0.04mm之间。

⑤ Khi phân phối dầu vào và ra, tấm van và tấm van phụ trên mặt đầu của khối xi lanh nên chịu tải trọng lệch tâm của khối xi lanh do sai số độ chính xác khi thêm T và mô-men xoắn nghiêng trong quá trình hoạt động. Nếu khoảng cách giữa mặt đầu của xi lanh và tấm van quá lớn, sự rò rỉ sẽ tăng lên và hiệu suất thể tích sẽ giảm, ngược lại, sự mài mòn của tấm van sẽ gia tăng. Điều kiện tiếp xúc lý tưởng là khối xi lanh được treo trên tấm phân phối dầu.

If the gap between the valve plate and the cylinder block is not uniform, it will aggravate the wear of the end face pair of the valve plate and the cylinder block, and affect the performance and service life of the pump. In order to control the uneven clearance, the following measures are taken on the structure of valve plate or cylinder block.

a. Plane distribution is called plane distribution because the combination of valve plate and cylinder block is plane. This structure has the advantages of easy processing and maintenance, axial compensation and so on. Therefore, this structure is widely used in small and medium displacement pumps and motors. For pumps and motors with large displacement, one of the following three measures is usually taken to make up for the uneven gap: one is to use the floating valve plate [Fig. H (a)] to automatically compensate the relative floating of valve plate 1 and flow sleeve 5; the other is to use the floating cylinder block [Fig. H (b)] to automatically compensate the relative floating of cylinder block 2 and flow sleeve 5 In comparison, it is convenient to process and easy to select the compression ratio, but the motion inertia of the cylinder block increases, the self-aligning performance is poor, and the self-priming performance of the pump is affected; third, the floating transition plate [Fig. H (c)] is used to compensate automatically by the relative floating of the transition plate 7 and the cylinder block 2, which is convenient for processing and maintenance, but with less compensation.

Ku plane valve distribution, sometimes a layer of bronze and other antifriction materials (Fig. f) is used to cover the bottom end face of the cylinder block to reduce the wear of the joint surface between the valve plate and the cylinder block.

b. Iphothi ye-spherical iboniswa kwiMifanekiso I. ukusukela kokuhlangana kwephothi yeplate 1 kunye necilindrical block 2 kuyispherical, ibizwa ngokuba yi-spherical port. Le ndlela inendawo ezilungileyo yokuzimela kwaye ingakwazi ukuzilungisa ngokuzenzekelayo. Kodwa ukucubungula ubuso be-spherical kudinga imishini ekhethekileyo, ukunemba okuphezulu kunye nokugcinwa okungafanelekanga.
