Wear glasses plate nose at the middle of its first occurrence, the greater the gap between the glasses, plates and cutting ring, wear faster. Therefore you must always pay attention to the gap between the price of a small concrete pump glasses, plates and cutting ring, once found the gap increases, the need to immediately tighten shaped nut or replace worn parts, to prevent mortar into the friction surface. When the rubber spring loses its elasticity, to be replaced immediately. You can fix the glasses plate cutting ring and technical specification for concrete pumping construction, continue to use the available electrode welding. Luoyang Great Locomotive Equipment Co., Ltd. is the first professional, focus on the production of fine aggregate concrete pump concrete pump manufacturers, with advanced production equipment fine aggregate concrete pump, senior engineer of the R & D team and perfect after-sales service team. Welcome friends to guide field trips! Luoyang Great Locomotive Equipment Co., Ltd. is the first professional, focus on the production of fine aggregate concrete pump manufacturers, production, sales and leasing of fine aggregate concrete pump 20L, 30L, 40L; sales of fine aggregate concrete pipes, fasteners, and change diameter pipe, elbow, pipe clamps and apron, etc; undertake research curious equipment machinery manufacturing, deep foundation reinforcement works, slope supporting engineering, anchor reinforcement works. Following by us to provide you with: the need to preheat fine stone pump tops for fine stone pump, in must be carried out before the road is preheated coat, do not underestimate this link. Because the fine stone pump reach the construction site, upload the pumping system is also to be part of the warm-up, otherwise it can not be normal construction. Usual practice of fine stone pump tops preheated in the case of the engine running, turn coat PTO. When the pump passive operation for some time, hydraulic oil temperature rises to a predetermined value, the fluid viscosity is attained normal working condition, so preheat upload is complete. Technical specification for concrete pumping construction, Luoyang Great (certified), concrete pumps and equipment provided by the Luoyang Great Locomotive Company. Luoyang Great Locomotive Equipment Co. (www.lybotxsb.com) is Luoyang, machining leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
