Features: small size, light weight, compact, simple operation, high pressure, low flow, low-pressure pump can be prepared in order to improve efficiency. On the basis of the crude way, increase the variety of hydraulic components. Such as solenoid valve, pressure relays, remote control switches sbd14e hand pumps, hydraulic lock. It can be used at any pressure within the rated pressure. Application: The company's products can directly pressure test on pressure vessel, equipped with special tools for lifting, bending, straightening, pressing, cutting, riveting, lifting, stretching, removable, perforated metal and other kind of job. Hydraulic hand pump glitch prevention when used hydraulic hand pump or the installation process will use some common faults, if these common faults that you know in advance, then the installation is again able to prevent the advance, which is a hydraulic hand pump installation, use definitely a good thing single-acting hydraulic hand pump, today Xiaobian put these common problems you summed up: Grades according to the season to add or replace the oil to meet the requirements of the provisions of the sbd20d manual pump oil, remove oil foreign body within the tube, tighten the bolt or nut joints; hydraulic hand pump replacement of aging or damaged oil seal or "O" ring seal gasket; hydraulic hand pump to replace worn gear pump or pump bushings, wear light in flat end mill will be smooth. Its flatness tolerance 0.03mm; lower than the upper end surface of the sleeve hydraulic hand pump plane (normal less than 2.5 ~ 2.6mm), such as ultra-poor should be the next bushes plus 0.1 ~ 0.2mm copper to compensate for installation when it should be put into the sleeve at the rear axle; unloading film and seal rings must be put into the oil chamber, two sleeves in order to maintain balance. Unloading piece seal ring should have a 0.5mm preload amount; the guide wire should be able to simultaneously stretch the upper and lower sleeve toward the direction of rotation of the driven gear to reverse a slight angle, so that the main, two driven gear sleeve machining plane closely fit; lorry tools | Weinan hand pumps | hydraulic force provided by the Texas Lu Lu of the hydraulic machinery plant.
