Reciprocating pump overhauling procedure Ridges will eventually develop at the limits of the piston ring travel and these must be removed. Later on two or three pistons were provided to raise compression speeds and give greater capacity. 2 The Pump The conventional compressor pump was a piston in a cylinder. A mechanic who is going to overhaul a pump must be familiar with the pump's specifications and any is usually indicated by excessive pump shock and noise. 4 Reciprocating pumps 4 1. Many pump problems and many packing or cup failures are directly traceable to a starved suction condition. Figure 1: Pump Overhaul Preparations A pump overhaul begins the same way that any other type of mechanical maintenance work begins: with careful preparation. 7 Mechanical seals and seal housings 38 The overhaul procedure for a reciprocating compressor involves several steps to ensure a comprehensive revamp. Copyrightdisclaimer under section 107 of the copyright1976, allowance is made for Aug 27, 2015 ยท Most of the moving parts in the pump will require examination during overhaul. 5 Shaft 34 2. Next, open inspection doors and loosen nut 1. 3 Types of pumps 3 1. Consult Myers Reciprocating Pump Manual or factory for temperature and speed limitations. When pumping liquids that are heated, reduce pump speed to avoid suction problems. 1. 1 Introduction 19 2. First, disconnect all auxiliary lines and decouple the coupling to remove the crankcase foundation bolts, allowing the total unit to be transferred to a workshop for carrying out the overhaul. 4 Wearing rings 31 2. 4. 6 Stuffing boxes 35 2. References pump. A few compressor manufacturers suggest rotary pumps, which are usually much faster and very much quieter than reciprocating pumps. A good first step is to check the pump manufacturer's instruction manual. The pump piston, rings and cylinder liner must also be thoroughly checked. 5 Other types of pumps 11 1. 3 Pump casings 25 2. 6 Centrifugal pumps 12 2 Centrifugal Pumps: Design and Construction 19 2. 2 Impellers 19 2. The suction and discharge valves must be refaced or ground in as required. . #Saheemkhan#marinehelpbot-***Disclaimervideo is for education purpose only. sidtvppvemfcvndvlelqbdigzboylqfeluomoffuyffairdaqd
